During mammalian cell growth and differentiation, the unfolded protein response (UPR) homeostatically adjusts endoplasmic reticulum (ER) protein-folding capacity to match changing cellular secretory demands. However, under high/chronic ER stress conditions the UPR triggers apoptosis. This dichotomy is promoted by differential activation levels of the ER transmembrane kinase/endoribonuclease (RNase) IRE1α. IRE1α kinase auto-phosphorylation operates as a rheostat to control downstream RNase-induced outputs that either sustain adaptive ER protein-folding or cause apoptosis. The IRE1α RNase can be controlled allosterically by kinase inhibitors that at maximal occupancy either fully inactivate or activate the RNAse. Overwhelming of protein folding and structural maturation in the early secretory pathway leads to accumulation of misfolded and immature secretory proteins in the endoplasmic reticulum (ER) (PMIDs: 22116877). Eukaryotic cells evolved intracellular signaling pathways to respond to such “ER stress”. These “Unfolded Protein Response” (UPR) pathways maintain cellular secretory function and physiological health in the face of remediable ER stress (PMIDs: 29107536). First discovered in unicellular eukaryotes, UPR pathways promote homeostatic/adaptive outputs through transcriptional upregulation of ER protein-folding and quality-control factors that extract terminally misfolded proteins back to the cytosol for degradation. However, in mammalian cells experiencing ER stress levels that cannot be mitigated by these adaptive arms, the UPR triggers programmed cell death (PCD), typically through mitochondrial apoptosis (PMIDs: 29107536). Multi-cellular organisms may benefit from culling irreversibly ER-stressed cells because the protein cargo that surviving cells continue to secrete is more likely to be pristine. However, in chronic states of such “terminal” UPR activation, the large-scale decrement of cells through unchecked PCD may actively promote cell degenerative diseases, such as diabetes mellitus (PMCID 5568783). One critical life-death switch in the UPR is governed by the ER transmembrane multi-domain sensor protein, IRE1α. IRE1α is activated upon ER stress elevation, causing this sensor to self-associate in the ER membrane. This event causes IRE1α's cytosolic Ser/Thr kinase to trans auto-phosphorylate, which results in subsequent activation of its C-terminal endoribonuclease (RNase) catalytic domain. The range of available IRE1α RNase activation states runs a gamut from the inactive, the active, to the hyperactive, with the level of activity controlled rheostatically by the upstream kinase module. From its inactive monomeric state, low-level kinase/RNase activation (caused by dimerization) initiates (adaptive) XBP1 mRNA transcription factor frame-shift splicing, while high-level kinase/RNase hyperactivation (due to homo-oligomerization) expands the RNase substrate repertoire to myriad ER-localized mRNAs that become endonucleolytically cleaved (in a process termed RIDD), (PMCIDs: 2762408, 4244221), thus initiating apoptosis. Thus, for maintaining cellular homeostasis, a priori, the “sweet spot” for IRE1α RNase activation may lie at a level wherein XBP1 mRNA splicing remains permissible, but without the initiation of RIDD. The cellular effects of such a meta-stable activation state have even been demonstrated with IRE1α mutants (some found naturally as somatic mutations in cancers that act as RNase hypomorphs) and chemical-genetic (“bumped inhibitor/holed kinase”) systems (PMIDs: 25018104 and 19665977). But while it has been established that ATP-competitive inhibitors can control endogenous IRE1α's RNase activity through the kinase domain, these allosteric modulators have largely been shown to enforce opposite extremes of activation states (PMID 23086298). Therefore, an optimal mode of engaging endogenous IRE1α's ATP-binding site has hitherto been unachievable. Disclosed herein, inter alia, are solutions to these and other problems known in the art.

The terms “halo” or “halogen,” by themselves or as part of another substituent, mean, unless otherwise stated, a fluorine, chlorine, bromine, or iodine atom. Additionally, terms such as “haloalkyl” are meant to include monohaloalkyl and polyhaloalkyl. For example, the term “halo(C1-C4)alkyl” includes, but is not limited to, fluoromethyl, difluoromethyl, trifluoromethyl, 2,2,2-trifluoroethyl, 4-chlorobutyl, 3-bromopropyl, and the like.

A fused ring aryl refers to multiple rings fused together wherein at least one of the fused rings is an aryl ring and wherein the multiple rings are attached to the parent molecular moiety through any carbon atom contained within an aryl ring of the multiple rings. The term “heteroaryl” refers to aryl groups (or rings) that contain at least one heteroatom such as N, O, or S, wherein the nitrogen and sulfur atoms are optionally oxidized, and the nitrogen atom(s) are optionally quaternized. Thus, the term “heteroaryl” includes fused ring heteroaryl groups (i.e., multiple rings fused together wherein at least one of the fused rings is a heteroaromatic ring and wherein the multiple rings are attached to the parent molecular moiety through any atom contained within a heteroaromatic ring of the multiple rings). A 5,6-fused ring heteroarylene refers to two rings fused together, wherein one ring has 5 members and the other ring has 6 members, and wherein at least one ring is a heteroaryl ring.

Spirocyclic rings are two or more rings wherein adjacent rings are attached through a single atom. The individual rings within spirocyclic rings may be identical or different. Individual rings in spirocyclic rings may be substituted or unsubstituted and may have different substituents from other individual rings within a set of spirocyclic rings. Possible substituents for individual rings within spirocyclic rings are the possible substituents for the same ring when not part of spirocyclic rings (e.g., substituents for cycloalkyl or heterocycloalkyl rings). Spirocylic rings may be substituted or unsubstituted cycloalkyl, substituted or unsubstituted cycloalkylene, substituted or unsubstituted heterocycloalkyl or substituted or unsubstituted heterocycloalkylene and individual rings within a spirocyclic ring group may be any of the immediately previous list, including having all rings of one type (e.g., all rings being substituted heterocycloalkylene wherein each ring may be the same or different substituted heterocycloalkylene). When referring to a spirocyclic ring system, heterocyclic spirocyclic rings means a spirocyclic rings wherein at least one ring is a heterocyclic ring and wherein each ring may be a different ring. When referring to a spirocyclic ring system, substituted spirocyclic rings means that at least one ring is substituted and each substituent may optionally be different.

The term “alkylarylene” as an arylene moiety covalently bonded to an alkylene moiety (also referred to herein as an alkylene linker). In embodiments, the alkylarylene group has the formula:
An alkylarylene moiety may be substituted (e.g., with a substituent group) on the alkylene moiety or the arylene linker (e.g., at carbons 2, 3, 4, or 6) with halogen, oxo, —N3, —CF3, —CCl3, —CBr3, —CI3, —CN, —CHO, —OH, —NH2, —COOH, —CONH2, —NO2, —SH, —SO2CH3, —SO3H, —OSO3H, —SO2NH2, —NHNH2, —ONH2, —NHC(O)NHNH2, substituted or unsubstituted —C1-C5 alkyl or substituted or unsubstituted 2 to 5 membered heteroalkyl).

Each of the above terms (e.g., “alkyl,” “heteroalkyl,” “cycloalkyl,” “heterocycloalkyl,” “aryl,” and “heteroaryl”) includes both substituted and unsubstituted forms of the indicated radical. Preferred substituents for each type of radical are provided below.
Substituents for the alkyl and heteroalkyl radicals (including those groups often referred to as alkylene, alkenyl, heteroalkylene, heteroalkenyl, alkynyl, cycloalkyl, heterocycloalkyl, cycloalkenyl, and heterocycloalkenyl) can be one or more of a variety of groups selected from, but not limited to, —OR′, ═O, ═NR′, ═N—OR′, —NR′R″, —SR′, -halogen, —SiR′R″R′″, —OC(O)R′, —C(O)R′, —CO2R′, —CONR′R″, —OC(O)NR′R″, —NR″C(O)R′, —NR′—C(O)NR″R′″, —NR″C(O)2R′, —NR—C(NR′R″R′″)═NR″″—, —NR—C(NR′R″)═NR′″, —S(O)R′, —S(O)2R′, —S(O)2NR′R″, —NRSO2R′, —NR′NR″R′″, —ONR′R″, —NR′C(O)NR″NR″R″″—CN, —NO2, —NRSO2R″, —NR′C(O)R″, —NR′C(O)—OR″, —NR′OR″, in a number ranging from zero to (2m′+1), where m′ is the total number of carbon atoms in such radical. R, R′, R″, R′″, and R″″ each preferably independently refer to hydrogen, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl (e.g., aryl substituted with 1-3 halogens), substituted or unsubstituted heteroaryl, substituted or unsubstituted alkyl, alkoxy, or thioalkoxy groups, or arylalkyl groups. When a compound described herein includes more than one R group, for example, each of the R groups is independently selected as are each R′, R″, R′″, and R″″ group when more than one of these groups is present. When R′ and R″ are attached to the same nitrogen atom, they can be combined with the nitrogen atom to form a 4-, 5-, 6-, or 7-membered ring. For example, —NR′R″ includes, but is not limited to, 1-pyrrolidinyl and 4-morpholinyl. From the above discussion of substituents, one of skill in the art will understand that the term “alkyl” is meant to include groups including carbon atoms bound to groups other than hydrogen groups, such as haloalkyl (e.g., —CF3 and —CH2CF3) and acyl (e.g., —C(O)CH3, —C(O)CF3, —C(O)CH2OCH3, and the like).
Similar to the substituents described for the alkyl radical, substituents for the aryl and heteroaryl groups are varied and are selected from, for example: —OR′, —NR′R″, —SR′, -halogen, —SiR′R″R′″, —OC(O)R′, —C(O)R′, —CO2R′, —CONR′R″, —OC(O)NR′R″, —NR″C(O)R′, —NR′—C(O)NR″R′″, —NR″C(O)2R′, —NR—C(NR′R″R′″)═NR″″, —NR—C(NR′R″)═NR′″, —S(O)R′, —S(O)2R′, —S(O)2NR′R″, —NRSO2R′, —NR′NR″R′″, —ONR′R″, —NR′C(O)NR″NR′″R″″, —CN, —NO2, —R′, —N3, —CH(Ph)2, fluoro(C1-C4)alkoxy, and fluoro(C1-C4)alkyl, —NR′SO2R″, —NR′C(O)R″, —NR′C(O)—OR″, —NR′OR″, in a number ranging from zero to the total number of open valences on the aromatic ring system; and where R′, R″, R′″, and R″″ are preferably independently selected from hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl. When a compound described herein includes more than one R group, for example, each of the R groups is independently selected as are each R′, R″, R′″, and R″″ groups when more than one of these groups is present.
Substituents for rings (e.g., cycloalkyl, heterocycloalkyl, aryl, heteroaryl, cycloalkylene, heterocycloalkylene, arylene, or heteroarylene) may be depicted as substituents on the ring rather than on a specific atom of a ring (commonly referred to as a floating substituent). In such a case, the substituent may be attached to any of the ring atoms (obeying the rules of chemical valency) and in the case of fused rings or spirocyclic rings, a substituent depicted as associated with one member of the fused rings or spirocyclic rings (a floating substituent on a single ring), may be a substituent on any of the fused rings or spirocyclic rings (a floating substituent on multiple rings). When a substituent is attached to a ring, but not a specific atom (a floating substituent), and a subscript for the substituent is an integer greater than one, the multiple substituents may be on the same atom, same ring, different atoms, different fused rings, different spirocyclic rings, and each substituent may optionally be different. Where a point of attachment of a ring to the remainder of a molecule is not limited to a single atom (a floating substituent), the attachment point may be any atom of the ring and in the case of a fused ring or spirocyclic ring, any atom of any of the fused rings or spirocyclic rings while obeying the rules of chemical valency. Where a ring, fused rings, or spirocyclic rings contain one or more ring heteroatoms and the ring, fused rings, or spirocyclic rings are shown with one more floating substituents (including, but not limited to, points of attachment to the remainder of the molecule), the floating substituents may be bonded to the heteroatoms. Where the ring heteroatoms are shown bound to one or more hydrogens (e.g., a ring nitrogen with two bonds to ring atoms and a third bond to a hydrogen) in the structure or formula with the floating substituent, when the heteroatom is bonded to the floating substituent, the substituent will be understood to replace the hydrogen, while obeying the rules of chemical valency.
Two or more substituents may optionally be joined to form aryl, heteroaryl, cycloalkyl, or heterocycloalkyl groups. Such so-called ring-forming substituents are typically, though not necessarily, found attached to a cyclic base structure. In one embodiment, the ring-forming substituents are attached to adjacent members of the base structure. For example, two ring-forming substituents attached to adjacent members of a cyclic base structure create a fused ring structure. In another embodiment, the ring-forming substituents are attached to a single member of the base structure. For example, two ring-forming substituents attached to a single member of a cyclic base structure create a spirocyclic structure. In yet another embodiment, the ring-forming substituents are attached to non-adjacent members of the base structure.

In a recited claim or chemical formula description herein, each R substituent or L linker that is described as being “substituted” without reference as to the identity of any chemical moiety that composes the “substituted” group (also referred to herein as an “open substitution” on an R substituent or L linker or an “openly substituted” R substituent or L linker), the recited R substituent or L linker may, in embodiments, be substituted with one or more first substituent groups as defined below.
The first substituent group is denoted with a corresponding first decimal point numbering system such that, for example, R1 may be substituted with one or more first substituent groups denoted by R1.1, R2 may be substituted with one or more first substituent groups denoted by R2.1, R3 may be substituted with one or more first substituent groups denoted by R3.1, R4 may be substituted with one or more first substituent groups denoted by R4.1, R5 may be substituted with one or more first substituent groups denoted by R5.1, and the like up to or exceeding an R100 that may be substituted with one or more first substituent groups denoted by R100.1. As a further example, R1A may be substituted with one or more first substituent groups denoted by R1A.1, R2A may be substituted with one or more first substituent groups denoted by R2A.1, R3A may be substituted with one or more first substituent groups denoted by R3A.1, R4A may be substituted with one or more first substituent groups denoted by R4A.1, R5A may be substituted with one or more first substituent groups denoted by R5A.1 and the like up to or exceeding an R100A may be substituted with one or more first substituent groups denoted by R100A.1.

Thus, each numbered R group or L group (alternatively referred to herein as RWW or LWW wherein “WW” represents the stated superscript number of the subject R group or L group) described herein may be substituted with one or more first substituent groups referred to herein generally as RWW.1 or RLWW.1 respectively. In turn, each first substituent group (e.g., R1.1, R2.1, R3.1, R4.1, R5.1 . . . R100.1; R1A.1, R2A.1, R3A.1, R4A.1, R5A.1 . . . R100A.1; RL1.1, RL2.1, RL3.1, RL4.1, RL5.1 . . .

R100A.2, RL1.2, RL2.2, RL3.2, RL4.2, RL5.2 . . . RL100.2, respectively).

Finally, each second substituent group (e.g., R1.2, R2.2, R3.2, R4.2, R5.2 . . . R100.2; R1A.2, R2A.2, R3A.2, R4A.2, R5A.2 . . . R100A.2; RL1.2, RL2.2, RL3.2, RL4.2, RL5.2 . . . RL100.2) may be further substituted with one or more third substituent groups (e.g., R1.3, R2.3, R3.3, R4.3, R5.3 . . . R100.3, R1A.3, R2A.3, R3A.3, R4A.3, R5A.3, . . . R100A.3; RL1.3, RL2.3, RL3.3, RL4.3, RL5.3 . . . RL100.3; respectively). Thus, each second substituent group, which may alternatively be represented herein as RWW.2 as described above, may be further substituted with one or more third substituent groups, which may alternatively be represented herein as RWW.3. Each of the first substituent groups may be optionally different. Each of the second substituent groups may be optionally different. Each of the third substituent groups may be optionally different.
Thus, as used herein, RWW represents a substituent recited in a claim or chemical formula description herein which is openly substituted. “WW” represents the stated superscript number of the subject R group (1, 2, 3, 1A, 2A, 3A, 1B, 2B, 3B, etc.). Likewise, LWW is a linker recited in a claim or chemical formula description herein which is openly substituted. Again, “WW” represents the stated superscript number of the subject L group (1, 2, 3, 1A, 2A, 3A, 1B, 2B, 3B, etc.). As stated above, in embodiments, each RWW may be unsubstituted or independently substituted with one or more first substituent groups, referred to herein as RWW1; each first substituent group, RWW.1, may be unsubstituted or independently substituted with one or more second substituent groups, referred to herein as RWW.2; and each second substituent group may be unsubstituted or independently substituted with one or more third substituent groups, referred to herein as RWW.3. Similarly, each LWW linker may be unsubstituted or independently substituted with one or more first substituent groups, referred to herein as RLWW1; each first substituent group, RLWW.1, may be unsubstituted or independently substituted with one or more second substituent groups, referred to herein as RLWW.2; and each second substituent group may be unsubstituted or independently substituted with one or more third substituent groups, referred to herein as RLWW.3. Each first substituent group is optionally different. Each second substituent group is optionally different. Each third substituent group is optionally different. For example, if RWW is phenyl, the said phenyl group is optionally substituted by one or more RWW.1 groups as defined herein below, e.g., when RWW is RWW.2-substituted or unsubstituted alkyl, examples of groups so formed include but are not limited to itself optionally substituted by 1 or more RWW.2, which RWW.2 is optionally substituted by one or more RWW.3. By way of example when the RWW group is phenyl substituted by RWW1, which is methyl, the methyl group may be further substituted to form groups including but not limited to:

In the event that any R group recited in a claim or chemical formula description set forth herein (RWW substituent) is not specifically defined in this disclosure, then that R group (RWW group) is hereby defined as independently oxo, halogen, —CXWW3, —CHXWW2, —CH2XWW, —OCXWW3, —OCH2XWW, —OCHXWW2, —CN, —OH, —NH2, —COOH, —CONH2, —NO2, —SH, —SO3H, —OSO3H, —SO2NH2, —NHNH2, —ONH2, —NHC(O)NHNH2, —NHC(O)NH2, —NHC(NH)NH2, —NHSO2H, —NHC(O)H, —NHC(O)OH, —NHOH, —N3, RWW.1-substituted or unsubstituted alkyl (e.g., C1-C8, C1-C6, C1-C4, or C1-C2), RWW.1-substituted or unsubstituted heteroalkyl (e.g., 2 to 8 membered, 2 to 6 membered, 4 to 6 membered, 2 to 3 membered, or 4 to 5 membered), RWW.1-substituted or unsubstituted cycloalkyl (e.g., C3-C8, C3-C6, C4-C6, or C5-C6), RWW.1-substituted or unsubstituted heterocycloalkyl (e.g., 3 to 8 membered, 3 to 6 membered, 4 to 6 membered, 4 to 5 membered, or 5 to 6 membered), RWW.1-substituted or unsubstituted aryl (e.g., C6-C12, C6-C10, or phenyl), or RWW.1-substituted or unsubstituted heteroaryl (e.g., 5 to 12 membered, 5 to 10 membered, 5 to 9 membered, or 5 to 6 membered). XWW is independently —F, —Cl, —Br, or —I. Again, “WW” represents the stated superscript number of the subject R group (e.g., 1, 2, 3, 1A, 2A, 3A, 1B, 2B, 3B, etc.). RWW.1, RWW.2, and RWW.3 are as defined above.
In the event that any L linker group recited in a claim or chemical formula description set forth herein (i.e., an LWW substituent) is not explicitly defined, then that L group (LWW group) is herein defined as independently a bond, —O—, —NH—, —C(O)—, —C(O)NH—, —NHC(O)—, —NHC(O)NH—, —NHC(NH)NH—, —C(O)O—, —OC(O)—, —S—, —SO2—, —SO2NH—, RLWW.1-substituted or unsubstituted alkylene (e.g., C1-C8, C1-C6, C1-C4, or C1-C2), RLWW.1-substituted or unsubstituted heteroalkylene (e.g., 2 to 8 membered, 2 to 6 membered, 4 to 6 membered, 2 to 3 membered, or 4 to 5 membered), R-substituted or unsubstituted cycloalkylene (e.g., C3-C8, C3-C6, C4-C6, or C5-C6), RLWW.1-substituted or unsubstituted heterocycloalkylene (e.g., 3 to 8 membered, 3 to 6 membered, 4 to 6 membered, 4 to 5 membered, or 5 to 6 membered), RLWW.1-substituted or unsubstituted arylene (e.g., C6-C12, C6-C10, or phenyl), or RLWW.1-substituted or unsubstituted heteroarylene (e.g., 5 to 12 membered, 5 to 10 membered, 5 to 9 membered, or 5 to 6 membered). Again, “WW” represents the stated superscript number of the subject L group (1, 2, 3, 1A, 2A, 3A, 1B, 2B, 3B, etc.). RLWW.1, as well as RLWW.2 and RLWW.3 are as defined above.
Certain compounds of the present disclosure possess asymmetric carbon atoms (optical or chiral centers) or double bonds; the enantiomers, racemates, diastereomers, tautomers, geometric isomers, stereoisometric forms that may be defined, in terms of absolute stereochemistry, as (R)- or (S)- or, as (D)- or (L)- for amino acids, and individual isomers are encompassed within the scope of the present disclosure. The compounds of the present disclosure do not include those that are known in art to be too unstable to synthesize and/or isolate. The present disclosure is meant to include compounds in racemic and optically pure forms. Optically active (R)- and (S)-, or (D)- and (L)-isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. When the compounds described herein contain olefinic bonds or other centers of geometric asymmetry, and unless specified otherwise, it is intended that the compounds include both E and Z geometric isomers.
As used herein, the term “isomers” refers to compounds having the same number and kind of atoms, and hence the same molecular weight, but differing in respect to the structural arrangement or configuration of the atoms.
The term “tautomer,” as used herein, refers to one of two or more structural isomers which exist in equilibrium and which are readily converted from one isomeric form to another.
It will be apparent to one skilled in the art that certain compounds of this disclosure may exist in tautomeric forms, all such tautomeric forms of the compounds being within the scope of the disclosure.
Unless otherwise stated, structures depicted herein are also meant to include all stereochemical forms of the structure; i.e., the R and S configurations for each asymmetric center. Therefore, single stereochemical isomers as well as enantiomeric and diastereomeric mixtures of the present compounds are within the scope of the disclosure.
Unless otherwise stated, structures depicted herein are also meant to include compounds which differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures except for the replacement of a hydrogen by a deuterium or tritium, or the replacement of a carbon by 13C- or 14C-enriched carbon are within the scope of this disclosure.
The compounds of the present disclosure may also contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute such compounds. For example, the compounds may be radiolabeled with radioactive isotopes, such as for example tritium (3H), iodine-125 (125I) or carbon-14 (14C). All isotopic variations of the compounds of the present disclosure, whether radioactive or not, are encompassed within the scope of the present disclosure.
It should be noted that throughout the application that alternatives are written in Markush groups, for example, each amino acid position that contains more than one possible amino acid. It is specifically contemplated that each member of the Markush group should be considered separately, thereby comprising another embodiment, and the Markush group is not to be read as a single unit.
As used herein, the terms “bioconjugate” and “bioconjugate linker” refers to the resulting association between atoms or molecules of “bioconjugate reactive groups” or “bioconjugate reactive moieties”. The association can be direct or indirect. For example, a conjugate between a first bioconjugate reactive group (e.g., —NH2, —C(O)OH, —N-hydroxysuccinimide, or -maleimide) and a second bioconjugate reactive group (e.g., sulfhydryl, sulfur-containing amino acid, amine, amine sidechain containing amino acid, or carboxylate) provided herein can be direct, e.g., by covalent bond or linker (e.g., a first linker of second linker), or indirect, e.g., by non-covalent bond (e.g., electrostatic interactions (e.g., ionic bond, hydrogen bond, halogen bond), van der Waals interactions (e.g., dipole-dipole, dipole-induced dipole, London dispersion), ring stacking (pi effects), hydrophobic interactions and the like). In embodiments, bioconjugates or bioconjugate linkers are formed using bioconjugate chemistry (i.e., the association of two bioconjugate reactive groups) including, but are not limited to nucleophilic substitutions (e.g., reactions of amines and alcohols with acyl halides, active esters), electrophilic substitutions (e.g., enamine reactions) and additions to carbon-carbon and carbon-heteroatom multiple bonds (e.g., Michael reaction, Diels-Alder addition). These and other useful reactions are discussed in, for example, March, ADVANCED ORGANIC CHEMISTRY, 3rd Ed., John Wiley & Sons, New York, 1985; Hermanson, BIOCONJUGATE TECHNIQUES, Academic Press, San Diego, 1996; and Feeney et al., MODIFICATION OF PROTEINS; Advances in Chemistry Series, Vol. 198, American Chemical Society, Washington, D.C., 1982. In embodiments, the first bioconjugate reactive group (e.g., maleimide moiety) is covalently attached to the second bioconjugate reactive group (e.g., a sulfhydryl). In embodiments, the first bioconjugate reactive group (e.g., haloacetyl moiety) is covalently attached to the second bioconjugate reactive group (e.g., a sulfhydryl). In embodiments, the first bioconjugate reactive group (e.g., pyridyl moiety) is covalently attached to the second bioconjugate reactive group (e.g. a sulfhydryl). In embodiments, the first bioconjugate reactive group (e.g., —N hydroxysuccinimide moiety) is covalently attached to the second bioconjugate reactive group (e.g., an amine). In embodiments, the first bioconjugate reactive group (e.g., maleimide moiety) is covalently attached to the second bioconjugate reactive group (e.g., a sulfhydryl). In embodiments, the first bioconjugate reactive group (e.g., -sulfo-N-hydroxysuccinimide moiety) is covalently attached to the second bioconjugate reactive group (e.g., an amine).
Useful bioconjugate reactive moieties used for bioconjugate chemistries herein include, for example:
The bioconjugate reactive groups can be chosen such that they do not participate in, or interfere with, the chemical stability of the conjugate described herein. Alternatively, a reactive functional group can be protected from participating in the crosslinking reaction by the presence of a protecting group. In embodiments, the bioconjugate comprises a molecular entity derived from the reaction of an unsaturated bond, such as a maleimide, and a sulfhydryl group.
“Analog,” or “analogue” is used in accordance with its plain ordinary meaning within Chemistry and Biology and refers to a chemical compound that is structurally similar to another compound (i.e., a so-called “reference” compound) but differs in composition, e.g., in the replacement of one atom by an atom of a different element, or in the presence of a particular functional group, or the replacement of one functional group by another functional group, or the absolute stereochemistry of one or more chiral centers of the reference compound. Accordingly, an analog is a compound that is similar or comparable in function and appearance but not in structure or origin to a reference compound.
The terms “a” or “an,” as used in herein means one or more. In addition, the phrase “substituted with a[n],” as used herein, means the specified group may be substituted with one or more of any or all of the named substituents. For example, where a group, such as an alkyl or heteroaryl group, is “substituted with an unsubstituted C1-C20 alkyl, or unsubstituted 2 to 20 membered heteroalkyl,” the group may contain one or more unsubstituted C1-C20 alkyls, and/or one or more unsubstituted 2 to 20 membered heteroalkyls.
Moreover, where a moiety is substituted with an R substituent, the group may be referred to as “R-substituted.” Where a moiety is R-substituted, the moiety is substituted with at least one R substituent and each R substituent is optionally different. Where a particular R group is present in the description of a chemical genus (such as Formula (I)), a Roman alphabetic symbol may be used to distinguish each appearance of that particular R group. For example, where multiple R13 substituents are present, each R13 substituent may be distinguished as R13.A, R13.B, R13.C, R13.D, etc., wherein each of R13.A, R13.B, R13.C, R13.D, etc. is defined within the scope of the definition of R13 and optionally differently.
A “detectable agent” or “detectable moiety” is a composition, substance, element, or compound; or moiety thereof; detectable by appropriate means such as spectroscopic, photochemical, biochemical, immunochemical, chemical, magnetic resonance imaging, or other physical means. For example, useful detectable agents include 18F, 32P, 33P, 45Ti, 47Sc, 52Fe, 59Fe, 62Cu, 64Cu, 67Cu, 67Ga, 68Ga, 77As, 86Y, 90Y, 89Sr, 89Zr, 94Tc, 94Tc, 99mTc, 99Mo, 105Pd, 105Rh, 111Ag, 111In, 123I, 124I, 125I, 131I, 142-Pr, 143Pr, 149Pm, 153Sm, 154-1581Gd, 161Tb, 166Dy, 166Ho, 169Er, 175Lu, 177Lu, 186Re, 188Re, 189Re, 194Ir, 198Au, 199Au, 211At, 211Pb, 212Bi, 212Pb, 213Bi, 223Ra, 225Ac, Cr, V, Mn, Fe, Co, Ni, Cu, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, 32P, fluorophore (e.g. fluorescent dyes), electron-dense reagents, enzymes (e.g., as commonly used in an ELISA), biotin, digoxigenin, paramagnetic molecules, paramagnetic nanoparticles, ultrasmall superparamagnetic iron oxide (“USPIO”) nanoparticles, USPIO nanoparticle aggregates, superparamagnetic iron oxide (“SPIO”) nanoparticles, SPIO nanoparticle aggregates, monochrystalline iron oxide nanoparticles, monochrystalline iron oxide, nanoparticle contrast agents, liposomes or other delivery vehicles containing Gadolinium chelate (“Gd-chelate”) molecules, Gadolinium, radioisotopes, radionuclides (e.g., carbon-11, nitrogen-13, oxygen-15, fluorine-18, rubidium-82), fluorodeoxyglucose (e.g., fluorine-18 labeled), any gamma ray emitting radionuclides, positron-emitting radionuclide, radiolabeled glucose, radiolabeled water, radiolabeled ammonia, biocolloids, microbubbles (e.g., including microbubble shells including albumin, galactose, lipid, and/or polymers; microbubble gas core including air, heavy gas(es), perfluorcarbon, nitrogen, octafluoropropane, perflexane lipid microsphere, perflutren, etc.), iodinated contrast agents (e.g., iohexol, iodixanol, ioversol, iopamidol, ioxilan, iopromide, diatrizoate, metrizoate, ioxaglate), barium sulfate, thorium dioxide, gold, gold nanoparticles, gold nanoparticle aggregates, fluorophores, two-photon fluorophores, or haptens and proteins or other entities which can be made detectable, e.g., by incorporating a radiolabel into a peptide or antibody specifically reactive with a target peptide. A detectable moiety is a monovalent detectable agent or a detectable agent capable of forming a bond with another composition.
Radioactive substances (e.g., radioisotopes) that may be used as imaging and/or labeling agents in accordance with the embodiments of the disclosure include, but are not limited to, 18F, 32P, 33P, 45Ti, 47Sc, 52Fe, 59Fe, 62Cu, 64Cu, 67Cu, 67Ga, 68Ga, 77As, 86Y, 90Y, 89Sr, 89Zr, 94Tc, 94Tc, 99mTc, 99Mo, 105Pd, 105Rh, 111Ag, 111In, 123I, 124I, 125I, 131I, 142Pr, 143Pr, 149Pm, 153Sm, 154-1581Gd, 161Tb, 166Dy, 166Ho, 169Er, 175Lu, 177Lu, 186Re, 188Re, 189Re, 194Ir, 198Au, 199Au, 211At, 211Pb, 212Bi, 212Pb, 213Bi, 223Ra, 225Ac. Paramagnetic ions that may be used as additional imaging agents in accordance with the embodiments of the disclosure include, but are not limited to, ions of transition and lanthanide metals (e.g. metals having atomic numbers of 21-29, 42, 43, 44, or 57-71). These metals include ions of Cr, V, Mn, Fe, Co, Ni, Cu, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu.
Descriptions of compounds of the present disclosure are limited by principles of chemical bonding known to those skilled in the art. Accordingly, where a group may be substituted by one or more of a number of substituents, such substitutions are selected so as to comply with principles of chemical bonding and to give compounds which are not inherently unstable and/or would be known to one of ordinary skill in the art as likely to be unstable under ambient conditions, such as aqueous, neutral, and several known physiological conditions. For example, a heterocycloalkyl or heteroaryl is attached to the remainder of the molecule via a ring heteroatom in compliance with principles of chemical bonding known to those skilled in the art thereby avoiding inherently unstable compounds.
A person of ordinary skill in the art will understand when a variable (e.g., moiety or linker) of a compound or of a compound genus (e.g., a genus described herein) is described by a name or formula of a standalone compound with all valencies filled, the unfilled valence(s) of the variable will be dictated by the context in which the variable is used. For example, when a variable of a compound as described herein is connected (e.g., bonded) to the remainder of the compound through a single bond, that variable is understood to represent a monovalent form (i.e., capable of forming a single bond due to an unfilled valence) of a standalone compound (e.g., if the variable is named “methane” in an embodiment but the variable is known to be attached by a single bond to the remainder of the compound, a person of ordinary skill in the art would understand that the variable is actually a monovalent form of methane, i.e., methyl or —CH3). Likewise, for a linker variable (e.g., L1, L2, or L3 as described herein), a person of ordinary skill in the art will understand that the variable is the divalent form of a standalone compound (e.g., if the variable is assigned to “PEG” or “polyethylene glycol” in an embodiment but the variable is connected by two separate bonds to the remainder of the compound, a person of ordinary skill in the art would understand that the variable is a divalent (i.e., capable of forming two bonds through two unfilled valences) form of PEG instead of the standalone compound PEG).
The terms “bind” and “bound” as used herein is used in accordance with its plain and ordinary meaning and refers to the association between atoms or molecules. The association can be direct or indirect. For example, bound atoms or molecules may be bound, e.g., by covalent bond, linker (e.g., a first linker or second linker), or non-covalent bond (e.g., electrostatic interactions (e.g., ionic bond, hydrogen bond, halogen bond), van der Waals interactions (e.g., dipole-dipole, dipole-induced dipole, London dispersion), ring stacking (pi effects), hydrophobic interactions and the like).
The term “capable of binding” as used herein refers to a moiety (e.g., a compound as described herein) that is able to measurably bind to a target. In embodiments, where a moiety is capable of binding a target, the moiety is capable of binding with a Kd of less than about 10 μM, 5 μM, 1 μM, 500 nM, 250 nM, 100 nM, 75 nM, 50 nM, 25 nM, 15 nM, 10 nM, 5 nM, 1 nM, or about 0.1 nM.
As used herein, the term “salt” refers to acid or base salts of the compounds used in the methods of the present invention. Illustrative examples of acceptable salts are mineral acid (hydrochloric acid, hydrobromic acid, phosphoric acid, and the like) salts, organic acid (acetic acid, propionic acid, glutamic acid, citric acid and the like) salts, quaternary ammonium (methyl iodide, ethyl iodide, and the like) salts.
The term “pharmaceutically acceptable salts” is meant to include salts of the active compounds that are prepared with relatively nontoxic acids or bases, depending on the particular substituents found on the compounds described herein. When compounds of the present disclosure contain relatively acidic functionalities, base addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired base, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable base addition salts include sodium, potassium, calcium, ammonium, organic amino, or magnesium salt, or a similar salt. When compounds of the present disclosure contain relatively basic functionalities, acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired acid, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include those derived from inorganic acids like hydrochloric, hydrobromic, nitric, carbonic, monohydrogencarbonic, phosphoric, monohydrogenphosphoric, dihydrogenphosphoric, sulfuric, monohydrogensulfuric, hydriodic, or phosphorous acids and the like, as well as the salts derived from relatively nontoxic organic acids like acetic, propionic, isobutyric, maleic, malonic, benzoic, succinic, suberic, fumaric, lactic, mandelic, phthalic, benzenesulfonic, p-tolylsulfonic, citric, tartaric, oxalic, methanesulfonic, and the like. Also included are salts of amino acids such as arginate and the like, and salts of organic acids like glucuronic or galactunoric acids and the like (see, for example, Berge et al., “Pharmaceutical Salts”, Journal of Pharmaceutical Science, 1977, 66, 1-19). Certain specific compounds of the present disclosure contain both basic and acidic functionalities that allow the compounds to be converted into either base or acid addition salts.
Thus, the compounds of the present disclosure may exist as salts, such as with pharmaceutically acceptable acids. The present disclosure includes such salts. Non-limiting examples of such salts include hydrochlorides, hydrobromides, phosphates, sulfates, methanesulfonates, nitrates, maleates, acetates, citrates, fumarates, proprionates, tartrates (e.g., (+)-tartrates, (−)-tartrates, or mixtures thereof including racemic mixtures), succinates, benzoates, and salts with amino acids such as glutamic acid, and quaternary ammonium salts (e.g., methyl iodide, ethyl iodide, and the like). These salts may be prepared by methods known to those skilled in the art.
The neutral forms of the compounds are preferably regenerated by contacting the salt with a base or acid and isolating the parent compound in the conventional manner. The parent form of the compound may differ from the various salt forms in certain physical properties, such as solubility in polar solvents.
In addition to salt forms, the present disclosure provides compounds, which are in a prodrug form. Prodrugs of the compounds described herein are those compounds that readily undergo chemical changes under physiological conditions to provide the compounds of the present disclosure. Prodrugs of the compounds described herein may be converted in vivo after administration. Additionally, prodrugs can be converted to the compounds of the present disclosure by chemical or biochemical methods in an ex vivo environment, such as, for example, when contacted with a suitable enzyme or chemical reagent.
Certain compounds of the present disclosure can exist in unsolvated forms as well as solvated forms, including hydrated forms. In general, the solvated forms are equivalent to unsolvated forms and are encompassed within the scope of the present disclosure. Certain compounds of the present disclosure may exist in multiple crystalline or amorphous forms. In general, all physical forms are equivalent for the uses contemplated by the present disclosure and are intended to be within the scope of the present disclosure.
“Pharmaceutically acceptable excipient” and “pharmaceutically acceptable carrier” refer to a substance that aids the administration of an active agent to and absorption by a subject and can be included in the compositions of the present disclosure without causing a significant adverse toxicological effect on the patient. Non-limiting examples of pharmaceutically acceptable excipients include water, NaCl, normal saline solutions, lactated Ringer's, normal sucrose, normal glucose, binders, fillers, disintegrants, lubricants, coatings, sweeteners, flavors, salt solutions (such as Ringer's solution), alcohols, oils, gelatins, carbohydrates such as lactose, amylose or starch, fatty acid esters, hydroxymethycellulose, polyvinyl pyrrolidine, and colors, and the like. Such preparations can be sterilized and, if desired, mixed with auxiliary agents such as lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring, and/or aromatic substances and the like that do not deleteriously react with the compounds of the disclosure. One of skill in the art will recognize that other pharmaceutical excipients are useful in the present disclosure.
The term “preparation” is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component with or without other carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid dosage forms suitable for oral administration.
As used herein, the term “about” means a range of values including the specified value, which a person of ordinary skill in the art would consider reasonably similar to the specified value. In embodiments, about means within a standard deviation using measurements generally acceptable in the art. In embodiments, about means a range extending to +/−10% of the specified value. In embodiments, about includes the specified value.
“Contacting” is used in accordance with its plain ordinary meaning and refers to the process of allowing at least two distinct species (e.g., chemical compounds including biomolecules or cells) to become sufficiently proximal to react, interact or physically touch. It should be appreciated; however, the resulting reaction product can be produced directly from a reaction between the added reagents or from an intermediate from one or more of the added reagents that can be produced in the reaction mixture.
The term “contacting” may include allowing two species to react, interact, or physically touch, wherein the two species may be a compound as described herein and a protein or enzyme. In some embodiments contacting includes allowing a compound described herein to interact with a protein or enzyme that is involved in a signaling pathway.
As defined herein, the term “activation”, “activate”, “activating”, “activator” and the like in reference to a protein-inhibitor interaction means positively affecting (e.g., increasing) the activity or function of the protein relative to the activity or function of the protein in the absence of the activator. In embodiments activation means positively affecting (e.g., increasing) the concentration or levels of the protein relative to the concentration or level of the protein in the absence of the activator. The terms may reference activation, or activating, sensitizing, or up-regulating signal transduction or enzymatic activity or the amount of a protein decreased in a disease. Thus, activation may include, at least in part, partially or totally increasing stimulation, increasing or enabling activation, or activating, sensitizing, or up-regulating signal transduction or enzymatic activity or the amount of a protein associated with a disease (e.g., a protein which is decreased in a disease relative to a non-diseased control). Activation may include, at least in part, partially or totally increasing stimulation, increasing or enabling activation, or activating, sensitizing, or up-regulating signal transduction or enzymatic activity or the amount of a protein.
The terms “agonist,” “activator,” “upregulator,” etc. refer to a substance capable of detectably increasing the expression or activity of a given gene or protein. The agonist can increase expression or activity 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% or more in comparison to a control in the absence of the agonist. In certain instances, expression or activity is 1.5-fold, 2-fold, 3-fold, 4-fold, 5-fold, 10-fold or higher than the expression or activity in the absence of the agonist.
As defined herein, the term “inhibition”, “inhibit”, “inhibiting” and the like in reference to a protein-inhibitor interaction means negatively affecting (e.g., decreasing) the activity or function of the protein relative to the activity or function of the protein in the absence of the inhibitor. In embodiments inhibition means negatively affecting (e.g., decreasing) the concentration or levels of the protein relative to the concentration or level of the protein in the absence of the inhibitor. In embodiments, inhibition refers to reduction of a disease or symptoms of disease. In embodiments, inhibition refers to a reduction in the activity of a particular protein target. Thus, inhibition includes, at least in part, partially or totally blocking stimulation, decreasing, preventing, or delaying activation, or inactivating, desensitizing, or down-regulating signal transduction or enzymatic activity or the amount of a protein. In embodiments, inhibition refers to a reduction of activity of a target protein resulting from a direct interaction (e.g., an inhibitor binds to the target protein). In embodiments, inhibition refers to a reduction of activity of a target protein from an indirect interaction (e.g., an inhibitor binds to a protein that activates the target protein, thereby preventing target protein activation).
The terms “inhibitor,” “repressor” or “antagonist” or “downregulator” interchangeably refer to a substance capable of detectably decreasing the expression or activity of a given gene or protein. The antagonist can decrease expression or activity 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% or more in comparison to a control in the absence of the antagonist. In certain instances, expression or activity is 1.5-fold, 2-fold, 3-fold, 4-fold, 5-fold, 10-fold or lower than the expression or activity in the absence of the antagonist.
The term “expression” includes any step involved in the production of the polypeptide including, but not limited to, transcription, post-transcriptional modification, translation, post-translational modification, and secretion. Expression can be detected using conventional techniques for detecting protein (e.g., ELISA, Western blotting, flow cytometry, immunofluorescence, immunohistochemistry, etc.).
The term “modulator” refers to a composition that increases or decreases the level of a target molecule or the function of a target molecule or the physical state of the target of the molecule relative to the absence of the modulator.
The term “modulate” is used in accordance with its plain ordinary meaning and refers to the act of changing or varying one or more properties. “Modulation” refers to the process of changing or varying one or more properties. For example, as applied to the effects of a modulator on a target protein, to modulate means to change by increasing or decreasing a property or function of the target molecule or the amount of the target molecule.
The term “associated” or “associated with” in the context of a substance or substance activity or function associated with a disease means that the disease (e.g., cancer, cell degeneration disease) is caused by (in whole or in part), or a symptom of the disease is caused by (in whole or in part) the substance or substance activity or function.
The term “aberrant” as used herein refers to different from normal. When used to describe enzymatic activity or protein function, aberrant refers to activity or function that is greater or less than a normal control or the average of normal non-diseased control samples. Aberrant activity may refer to an amount of activity that results in a disease, wherein returning the aberrant activity to a normal or non-disease-associated amount (e.g., by administering a compound or using a method as described herein), results in reduction of the disease or one or more disease symptoms.
The term “signaling pathway” as used herein refers to a series of interactions between cellular and optionally extra-cellular components (e.g., proteins, nucleic acids, small molecules, ions, lipids) that conveys a change in one component to one or more other components, which in turn may convey a change to additional components, which is optionally propagated to other signaling pathway components.
In this disclosure, “comprises,” “comprising,” “containing” and “having” and the like can have the meaning ascribed to them in U.S. Patent law and can mean “includes,” “including,” and the like. “Consisting essentially of” or “consists essentially” likewise has the meaning ascribed in U.S. Patent law and the term is open-ended, allowing for the presence of more than that which is recited so long as basic or novel characteristics of that which is recited is not changed by the presence of more than that which is recited, but excludes prior art embodiments.

As used herein, the terms “metastasis,” “metastatic,” and “metastatic cancer” can be used interchangeably and refer to the spread of a proliferative disease or disorder, e.g., cancer, from one organ or another non-adjacent organ or body part. “Metastatic cancer” is also called “Stage IV cancer.” Cancer occurs at an originating site, e.g., breast, which site is referred to as a primary tumor, e.g., primary breast cancer. Some cancer cells in the primary tumor or originating site acquire the ability to penetrate and infiltrate surrounding normal tissue in the local area and/or the ability to penetrate the walls of the lymphatic system or vascular system circulating through the system to other sites and tissues in the body. A second clinically detectable tumor formed from cancer cells of a primary tumor is referred to as a metastatic or secondary tumor. When cancer cells metastasize, the metastatic tumor and its cells are presumed to be similar to those of the original tumor. Thus, if lung cancer metastasizes to the breast, the secondary tumor at the site of the breast consists of abnormal lung cells and not abnormal breast cells. The secondary tumor in the breast is referred to a metastatic lung cancer. Thus, the phrase metastatic cancer refers to a disease in which a subject has or had a primary tumor and has one or more secondary tumors. The phrases non-metastatic cancer or subjects with cancer that is not metastatic refers to diseases in which subjects have a primary tumor but not one or more secondary tumors. For example, metastatic lung cancer refers to a disease in a subject with or with a history of a primary lung tumor and with one or more secondary tumors at a second location or multiple locations, e.g., in the breast.
The terms “cutaneous metastasis” and “skin metastasis” refer to secondary malignant cell growths in the skin, wherein the malignant cells originate from a primary cancer site (e.g., breast). In cutaneous metastasis, cancerous cells from a primary cancer site may migrate to the skin where they divide and cause lesions. Cutaneous metastasis may result from the migration of cancer cells from breast cancer tumors to the skin.
The term “visceral metastasis” refers to secondary malignant cell growths in the internal organs (e.g., heart, lungs, liver, pancreas, intestines) or body cavities (e.g., pleura, peritoneum), wherein the malignant cells originate from a primary cancer site (e.g., head and neck, liver, breast). In visceral metastasis, cancerous cells from a primary cancer site may migrate to the internal organs where they divide and cause lesions. Visceral metastasis may result from the migration of cancer cells from liver cancer tumors or head and neck tumors to internal organs.
The terms “treating”, or “treatment” refers to any indicia of success in the therapy or amelioration of an injury, disease, pathology or condition, including any objective or subjective parameter such as abatement; remission; diminishing of symptoms or making the injury, pathology or condition more tolerable to the patient; slowing in the rate of degeneration or decline; making the final point of degeneration less debilitating; improving a patient's physical or mental well-being. The treatment or amelioration of symptoms can be based on objective or subjective parameters; including the results of a physical examination, neuropsychiatric exams, and/or a psychiatric evaluation. The term “treating” and conjugations thereof, may include prevention of an injury, pathology, condition, or disease. In embodiments, treating is preventing. In embodiments, treating does not include preventing.
“Treating” or “treatment” as used herein (and as well-understood in the art) also broadly includes any approach for obtaining beneficial or desired results in a subject's condition, including clinical results. Beneficial or desired clinical results can include, but are not limited to, alleviation or amelioration of one or more symptoms or conditions, diminishment of the extent of a disease, stabilizing (i.e., not worsening) the state of disease, prevention of a disease's transmission or spread, delay or slowing of disease progression, amelioration or palliation of the disease state, diminishment of the reoccurrence of disease, and remission, whether partial or total and whether detectable or undetectable. In other words, “treatment” as used herein includes any cure, amelioration, or prevention of a disease. Treatment may prevent the disease from occurring; inhibit the disease's spread; relieve the disease's symptoms (e.g., ocular pain, seeing halos around lights, red eye, very high intraocular pressure), fully or partially remove the disease's underlying cause, shorten a disease's duration, or do a combination of these things.
“Treating” and “treatment” as used herein include prophylactic treatment. Treatment methods include administering to a subject a therapeutically effective amount of an active agent. The administering step may consist of a single administration or may include a series of administrations. The length of the treatment period depends on a variety of factors, such as the severity of the condition, the age of the patient, the concentration of active agent, the activity of the compositions used in the treatment, or a combination thereof. It will also be appreciated that the effective dosage of an agent used for the treatment or prophylaxis may increase or decrease over the course of a particular treatment or prophylaxis regime. Changes in dosage may result and become apparent by standard diagnostic assays known in the art. In some instances, chronic administration may be required. For example, the compositions are administered to the subject in an amount and for a duration sufficient to treat the patient. In embodiments, the treating or treatment is not prophylactic treatment (e.g., the patient has a disease, the patient suffers from a disease).
The term “prevent” refers to a decrease in the occurrence of disease symptoms or disease in a patient. As indicated above, the prevention may be complete (no detectable symptoms) or partial, such that fewer symptoms are observed than would likely occur absent treatment.
“Patient” or “subject in need thereof” refers to a living organism suffering from or prone to a disease or condition that can be treated by administration of a pharmaceutical composition as provided herein. Non-limiting examples include humans, other mammals, bovines, rats, mice, dogs, monkeys, goat, sheep, cows, deer, and other non-mammalian animals. In some embodiments, a patient is human.
An “effective amount” is an amount sufficient for a compound to accomplish a stated purpose relative to the absence of the compound (e.g., achieve the effect for which it is administered, treat a disease, reduce enzyme activity, increase enzyme activity, reduce a signaling pathway, or reduce one or more symptoms of a disease or condition). An example of an “effective amount” is an amount sufficient to contribute to the treatment, prevention, or reduction of a symptom or symptoms of a disease, which could also be referred to as a “therapeutically effective amount.” A “reduction” of a symptom or symptoms (and grammatical equivalents of this phrase) means decreasing of the severity or frequency of the symptom(s), or elimination of the symptom(s). A “prophylactically effective amount” of a drug is an amount of a drug that, when administered to a subject, will have the intended prophylactic effect, e.g., preventing or delaying the onset (or reoccurrence) of an injury, disease, pathology or condition, or reducing the likelihood of the onset (or reoccurrence) of an injury, disease, pathology, or condition, or their symptoms. The full prophylactic effect does not necessarily occur by administration of one dose, and may occur only after administration of a series of doses. Thus, a prophylactically effective amount may be administered in one or more administrations. An “activity decreasing amount,” as used herein, refers to an amount of antagonist required to decrease the activity of an enzyme relative to the absence of the antagonist. A “function disrupting amount,” as used herein, refers to the amount of antagonist required to disrupt the function of an enzyme or protein relative to the absence of the antagonist. The exact amounts will depend on the purpose of the treatment, and will be ascertainable by one skilled in the art using known techniques (see, e.g., Lieberman, Pharmaceutical Dosage Forms (vols. 1-3, 1992); Lloyd, The Art, Science and Technology of Pharmaceutical Compounding (1999); Pickar, Dosage Calculations (1999); and Remington: The Science and Practice of Pharmacy, 20th Edition, 2003, Gennaro, Ed., Lippincott, Williams & Wilkins).
For any compound described herein, the therapeutically effective amount can be initially determined from cell culture assays. Target concentrations will be those concentrations of active compound(s) that are capable of achieving the methods described herein, as measured using the methods described herein or known in the art.
As is well known in the art, therapeutically effective amounts for use in humans can also be determined from animal models. For example, a dose for humans can be formulated to achieve a concentration that has been found to be effective in animals. The dosage in humans can be adjusted by monitoring compounds effectiveness and adjusting the dosage upwards or downwards, as described above. Adjusting the dose to achieve maximal efficacy in humans based on the methods described above and other methods is well within the capabilities of the ordinarily skilled artisan.
The term “therapeutically effective amount,” as used herein, refers to that amount of the therapeutic agent sufficient to ameliorate the disorder, as described above. For example, for the given parameter, a therapeutically effective amount will show an increase or decrease of at least 5%, 10%, 15%, 20%, 25%, 40%, 50%, 60%, 75%, 80%, 90%, or at least 100%. Therapeutic efficacy can also be expressed as “-fold” increase or decrease. For example, a therapeutically effective amount can have at least a 1.2-fold, 1.5-fold, 2-fold, 5-fold, or more effect over a control.
Dosages may be varied depending upon the requirements of the patient and the compound being employed. The dose administered to a patient, in the context of the present disclosure, should be sufficient to effect a beneficial therapeutic response in the patient over time. The size of the dose also will be determined by the existence, nature, and extent of any adverse side-effects. Determination of the proper dosage for a particular situation is within the skill of the practitioner. Generally, treatment is initiated with smaller dosages which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small increments until the optimum effect under circumstances is reached. Dosage amounts and intervals can be adjusted individually to provide levels of the administered compound effective for the particular clinical indication being treated. This will provide a therapeutic regimen that is commensurate with the severity of the individual's disease state.
As used herein, the term “administering” means oral administration, administration as a suppository, topical contact, intravenous, parenteral, intraperitoneal, intramuscular, intralesional, intrathecal, intranasal or subcutaneous administration, or the implantation of a slow-release device, e.g., a mini-osmotic pump, to a subject. Administration is by any route, including parenteral and transmucosal (e.g., buccal, sublingual, palatal, gingival, nasal, vaginal, rectal, or transdermal). Parenteral administration includes, e.g., intravenous, intramuscular, intra-arteriole, intradermal, subcutaneous, intraperitoneal, intraventricular, and intracranial. Other modes of delivery include, but are not limited to, the use of liposomal formulations, intravenous infusion, transdermal patches, etc. In embodiments, the administering does not include administration of any active agent other than the recited active agent.
“Co-administer” it is meant that a composition described herein is administered at the same time, just prior to, or just after the administration of one or more additional therapies. The compounds provided herein can be administered alone or can be coadministered to the patient. Coadministration is meant to include simultaneous or sequential administration of the compounds individually or in combination (more than one compound). Thus, the preparations can also be combined, when desired, with other active substances (e.g., to reduce metabolic degradation). The compositions of the present disclosure can be delivered transdermally, by a topical route, or formulated as applicator sticks, solutions, suspensions, emulsions, gels, creams, ointments, pastes, jellies, paints, powders, and aerosols.
A “cell” as used herein, refers to a cell carrying out metabolic or other function sufficient to preserve or replicate its genomic DNA. A cell can be identified by well-known methods in the art including, for example, presence of an intact membrane, staining by a particular dye, ability to produce progeny or, in the case of a gamete, ability to combine with a second gamete to produce a viable offspring. Cells may include prokaryotic and eukaryotic cells. Prokaryotic cells include but are not limited to bacteria. Eukaryotic cells include but are not limited to yeast cells and cells derived from plants and animals, for example mammalian, insect (e.g., spodoptera) and human cells. Cells may be useful when they are naturally nonadherent or have been treated not to adhere to surfaces, for example by trypsinization.
“Control” or “control experiment” is used in accordance with its plain ordinary meaning and refers to an experiment in which the subjects or reagents of the experiment are treated as in a parallel experiment except for omission of a procedure, reagent, or variable of the experiment. In some instances, the control is used as a standard of comparison in evaluating experimental effects. In some embodiments, a control is the measurement of the activity of a protein in the absence of a compound as described herein (including embodiments and examples).
The term “Ire1” or “Ire1α” or “ERN1” refers to the protein “Serine/threonine-protein kinase/endoribonuclease IRE1” a.k.a. “Endoplasmic reticulum to nucleus signaling 1”. In embodiments, “Ire1” or “Ire1α” or “ERN1” refers to the human protein. Included in the term “Ire1” or “Ire1α” or “ERN1” are the wildtype and mutant forms of the protein. In embodiments, “Ire1” or “Ire1α” or “ERN1” refers to the protein associated with Entrez Gene 2081, OMIM 604033, UniProt O75460, and/or RefSeq (protein) NM 001433. In embodiments, the reference numbers immediately above refer to the protein, and associated nucleic acids, known as of the date of filing of this application. In embodiments, “Ire1” or “Ire1α” or “ERN1” refers to the wildtype human protein. In embodiments, “Ire1” or “Ire1a” or “ERN1” refers to the wildtype human nucleic acid.
The compounds described herein can be used in combination with one another, with other active agents known to be useful in treating a disease associated with cells expressing a disease associated cellular component, or with adjunctive agents that may not be effective alone, but may contribute to the efficacy of the active agent.
In some embodiments, co-administration includes administering one active agent within 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 20, or 24 hours of a second active agent. Co-administration includes administering two active agents simultaneously, approximately simultaneously (e.g., within about 1, 5, 10, 15, 20, or 30 minutes of each other), or sequentially in any order. In some embodiments, co-administration can be accomplished by co-formulation, i.e., preparing a single pharmaceutical composition including both active agents. In other embodiments, the active agents can be formulated separately. In another embodiment, the active and/or adjunctive agents may be linked or conjugated to one another.
As a non-limiting example, the compounds described herein can be co-administered with anti-cancer agents or conventional chemotherapeutic agents including alkylating agents (e.g., cyclophosphamide, ifosfamide, chlorambucil, busulfan, melphalan, mechlorethamine, uramustine, thiotepa, nitrosoureas, etc.), anti-metabolites (e.g., 5-fluorouracil, azathioprine, methotrexate, leucovorin, capecitabine, cytarabine, floxuridine, fludarabine, gemcitabine, pemetrexed, raltitrexed, etc.), plant alkaloids (e.g., vincristine, vinblastine, vinorelbine, vindesine, podophyllotoxin, paclitaxel, docetaxel, etc.), topoisomerase inhibitors (e.g., irinotecan, topotecan, amsacrine, etoposide (VP16), etoposide phosphate, teniposide, etc.), antitumor antibiotics (e.g., doxorubicin, adriamycin, daunorubicin, epirubicin, actinomycin, bleomycin, mitomycin, mitoxantrone, plicamycin, etc.), platinum-based compounds (e.g., cisplatin, oxaloplatin, carboplatin, etc.), and the like.
In therapeutic use for the treatment of a disease, compound utilized in the pharmaceutical compositions of the present invention may be administered at the initial dosage of about 0.001 mg/kg to about 1000 mg/kg daily. A daily dose range of about 0.01 mg/kg to about 500 mg/kg, or about 0.1 mg/kg to about 200 mg/kg, or about 1 mg/kg to about 100 mg/kg, or about 10 mg/kg to about 50 mg/kg, can be used. The dosages, however, may be varied depending upon the requirements of the patient, the severity of the condition being treated, and the compound or drug being employed. For example, dosages can be empirically determined considering the type and stage of cancer diagnosed in a particular patient. The dose administered to a patient, in the context of the present invention, should be sufficient to affect a beneficial therapeutic response in the patient over time. The size of the dose will also be determined by the existence, nature, and extent of any adverse side-effects that accompany the administration of a compound in a particular patient. Determination of the proper dosage for a particular situation is within the skill of the practitioner. Generally, treatment is initiated with smaller dosages which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small increments until the optimum effect under circumstances is reached.

Viruses are obligatory intracellular parasites that hijack and usurp cellular synthetic functions for their replications. The early secretory pathway (especially the ER) can be the site of both entry into the cytosol and an initial site for packaging and egress. Either non-enveloped viruses such as such as coxsackieviruses, rotavirus, or poliovirus, or enveloped viruses such as influenza virus, herpes simplex virus (HSV), human immunodeficiency virus (HIV), and SARS CoV-2 (the coronavirus that causes COVID-19) all are reported to exhibit high ER stress. In the case of SARS CoV-2, the viral replication cycle and maturation of both structural and non structural proteins leads to upregulation of ER stress signaling components (PMCID: PMC7431030). Original SARS (CoV-1) and MERS both led to UPR upregulation (PMCID: PMC1563899). Thus, the role of coronaviruses in causing ER stress is established.

Described herein are new IRE1α kinase inhibitors that at full occupancy of the kinase domain cause partial antagonism of the RNase.
Atomic level resolution co-crystal structures show that these small molecule kinase inhibitors—which we named ‘PAIR’s for (Partial Antagonists of IRE1α RNase)—bind ATP-competitively in the kinase to partially displace the IRE1α kinase helix αC, leading to stabilization of dimeric IRE1α species. In insulin-producing beta cells, PAIRs permit adaptive XBP1 mRNA splicing, while quelling destructive/terminal outputs from extra-XBP1 mRNA endonucleolytic decay, thus preventing apoptosis. Preservation of XBP1 splicing by PAIRs permits B-cells to differentiate into immunoglobulin-producing plasma cells.
In summary, an intermediate RNAse-inhibitory “sweet spot”, achieved by PAIR-bound IRE1α, may capture a structural conformation naturally available to IRE1α that could represent a desirable therapeutic state for drugging this master UPR sensor/effector.
Here, we demonstrate that it is possible to design ATP-competitive inhibitors, which we call Partial Antagonists of IRE1α RNase (PAIRs), that fully engage IRE1α's kinase domain but only partially inhibit its RNase activity. By systematically defining the structural features of PAIRs that lead to stabilization of the kinase domain of IRE1α in this “intermediate” activation mode, we highlight new understanding of both the structure-activity relationships of PAIRs while comparing these to previous activators and full inhibitors of IRE1α.
Through atomic-resolution, co-crystal structures, we decipher structural rules that govern the basis of this intermediate activation conformational state. We show that the degree of outward displacement of the helix αC in IRE1α's kinase domain is the key determinant of these differential RNase activation states. We further show that enforcing such an optimal IRE1α RNase activation state in cells allows partial activation of the RNase, sufficient to largely splice XBP1 mRNA, while mostly inhibiting RIDD. Finally, we show that PAIRs have the unique ability to segregate distinct biological outputs of IRE1α in cellular systems by chiseling away destructive (RIDD-dependent) cell fate outputs from adaptive (XBP1 splicing-dependent) outputs. In this regard, PAIRs may represent a new pharmacological modality for addressing cell degeneration-namely by preserving an adaptive, while blunting, a terminal-UPR.
In order to better understand how to achieve an optimal intermediate RNase activation state through engagement of IRE1α's kinase domain, we first established a quantitative in vitro framework for characterizing how ATP-binding site occupancy influences RNase activity. It has been demonstrated that IRE1α must form a dimer in order for its RNase domain to be catalytically active (
Using this assay, we found that IRE1α*, which is basally autophosphorylated on its activation loop, demonstrated a dimerization affinity in the high nanomolar range (Kdimer=140 nM). A quantitatively dephosphorylated IRE1α* construct (dpIRE1α*) (
Next, we tested how a class of ATP-binding site ligands-called kinase inhibiting RNase attenuators (KIRAs)—that inactivate IRE1α's RNase activity through the kinase domain affect dimerization affinity. We found that IRE1α* was unable to form RNase active dimers at any concentration tested when bound to the highly potent KIRA, KIRA8, or even to a lower affinity KIRA (
We speculated that it should be possible to identify ATP-competitive ligands that only intermediately weaken the dimerization affinity of IRE1α, and hence preserve some RNase outputs, rather than enforce a fully monomeric state with completely crippled RNase activity, like KIRAs do.
To better understand how to design such partial antagonists of IRE1α's RNase activity, we explored ATP-binding site ligands based on the pyridine-pyrimidine scaffold of KIRA8 (
We reasoned that ATP-binding site ligands that are capable of partially antagonizing the RNase activity of IRE1α will likely contain substituents at the R3 (R3 shown in the figures and described in the figure descriptions is not necessarily identical to R3 described elsewhere herein, for example aspects, embodiments, and/or claims) position that are smaller than the 3-trifluoropropyl sulfonamide group of 2. Indeed, we found that compound 4, which contains a 2-trifluoroethylsulfonamide group at the R3 (R3 shown in the figures and described in the figure descriptions is not necessarily identical to R3 described elsewhere herein, for example aspects, embodiments, and/or claims) position, was capable of quantitatively inhibiting the kinase activity of IRE1α* but only partially (˜80%) inhibiting RNase activity (
We obtained a 1.85 Å resolution co-crystal structure of 7 (PAIR1) bound to IRE1α* to provide mechanistic insight into the partial RNase antagonism of PAIRs. As expected, PAIR1 occupies the ATP-binding site of IRE1α*, with the pyrimidine-pyridine scaffold forming two hydrogen-bonding interactions with the hinge region. Additional interactions include a hydrogen-bonding interaction between the naphthyl sulfonamide group and the backbone of the DFG-motif and a salt bridge between the piperidine substituent of PAIR1 and Glu651 in the α-H helix (
We speculated that differences in how PAIRs and KIRAs influence the conformation of the αC-helix, which is a dynamic regulatory element that lines IRE1α*'s ATP-binding pocket, could explain the variable effects that they have on dimerization affinity. It has previously been demonstrated that when the αC-helix of IRE1α is in the active conformation it forms a significant portion of the RNase active back-to-back dimer interface. Consistent with the ability of PAIR1 to partially inhibit IRE1α*'s RNase activity, the αC-helix of the PAIR1-IRE1α* complex is rotated and displaced from the active conformation (
The differences that we observe between PAIRs and KIRAs in their modulation of IRE1α*'s dimerization affinity in solution are reflected in the oligomeric states of the PAIR1-IRE1α and AMG-16-IRE1α complexes in crystal structures. We observed that PAIR1-bound IRE1α crystallized as a back-to-back dimer, while the AMG-16-bound structure of IRE1α was monomeric (
Prior to conducting cellular studies with PAIRs, we first performed comprehensive kinome selectivity profiling using a chemical proteomic method (
We next tested PAIR1 and KIRA9 in an INS-1 rat insulinoma stable cell line where IRE1α activation can be achieved through conditional overexpression of a mouse IRE1α transgene (Han et al., 2009). We have previously demonstrated that this maneuver causes IRE1α to self-associate, trans-autophosphorylate, and triggers XBP1 mRNA splicing and extra-XBP1 endonucleolytic mRNA decay (RIDD) without the need for pleiotropic ER stress inducing agents. Using phostag-acrylamide gels, we found that both PAIR1 and KIRA9 were able to equivalently block the autophosphorylation induced by conditional overexpression of IRE1α at almost identical concentrations (
In contrast, we observed that PAIR1 largely preserved XBP1 mRNA splicing and expression of the frame-shifted Xbp1s transcription factor in this system, while KIRA9 more vigorously inhibited these outputs, despite the observation that kinase domain engagement was equivalent between the two compounds at the concentration tested (
Next, to systematically compare the transcriptomic effects of PAIR1 and KIRA9, we profiled INS-1 cells that conditionally overexpress IRE1α by RNA Seq. As above (
We next interrogated RIDD target gene expression in these cells (
A priori, if XBP1 mRNA splicing inhibition is irrelevant to entry of cells into apoptosis from IRE1α-mediated RNase hyperactivation, then PAIR1 and KIRA9 should perform equivalently to each other in cytoprotection assays, because they share the common feature that they cause equivalent rescue of extra-XBP1 ER-localized mRNA endonucleolytic decay, even though they diverge against the endpoint of inhibiting XBP1 mRNA splicing. Consistent with this notion, we observed that both PAIR1 and KIRA9 markedly reduced the generation of cleaved caspase 3 and showed significant cytoprotective efficacy in a mitochondrial apoptosis assay (Annexin-V positivity) (
We previously showed that IRE1α RIDD activity promotes apoptosis by upregulating TXNIP in INS-1 cells that overexpress IRE1α (PMCID 4014071, 4244221). TXNIP upregulation was blocked by both PAIR1 and KIRA9 (
Previous studies have demonstrated that plasma cell differentiation and function are highly dependent upon spliced XBP1 transcription factor function. Therefore, we sought to compare the sensitivity of this process to both KIRAs and PAIRs. To this end, we assessed how KIRA8, KIRA9, and PAIR1 affected the differentiation of lipopolysaccharide (LPS)-treated mouse splenocytes into antibody-secreting plasma cells. Total live number of CD19+ B-cells were assessed and plasma cells were quantified on the basis of B220 downregulation and CD138 expression by flow cytometry (
Finally, we confirmed that the LPS treatment of the splenocytes triggered elevations in XBP1 mRNA splicing, which were reversed with KIRA9, but not with PAIR1 (
Ire1 mediates a simple, linear UPR pathway through splicing of Hac1 mRNA in S. cerevisiae PMID: 9348528, PMID: 8898193, and appears to exclusively promote RIDD in S. pombe PMID: 23066505. In both these well studied models, Ire1 outputs restore ER secretory homeostasis. In contrast to these lower eukaryotes, multicellular eukaryotes—especially mammals—have evolved an expanded number of UPR outputs, and other UPR sensor/effectors; yet the widely-expressed IRE1α ortholog has preserved both non-conventional splicing features (through frameshift splicing of XBP1 mRNA) and RIDD PMID: 19651891, PMID: 19665977. The first studies to bifurcate these two outputs used allele-sensitized versions of IRE1α, which as with yeast Ire1 PMID: 14564015, can be activated through the provision of a designer kinase inhibitor—1NM-PP1—fulfills a “co-factor” requirement in the enlarged kinase domain nucleotide-binding pocket (1642G) to activate from a distance (allosterically) the XBP1 mRNA splicing feature of the RNase, while averting RIDD PMID: 18035051, 19651891, 19665977.
Furthermore, the scope of biological outputs of XBP1 mRNA and RIDD have been widely studied, but are still largely debated. The requirement of XBP1 transcription factor in de novo differentiation of progenitor cells to mature professional terminally differentiated cells was first discovered in the B-cell to plasma cell transition PMID: 11460154; IRE1α-mediated splicing of XBP1 mRNA is critical for this transition and for other examples in ontogeny PMID: 11780124. The role of RIDD has been studied in many contexts. In our previous studies, the pharmacological inhibition of RIDD using KIRAs prevents apoptosis. At maximal occupancy, KIRAs monomerize IRE1α and thereby quench XBP1 splicing. Here, we developed ATP-competitive ligands—PAIRs—that achieve an intermediate dimerization state of the kinase/RNase domain of IRE1α, which allows inhibition of RIDD while preserving XBP1 mRNA splicing. We were able to achieve this intermediate dimerization state by introducing substituents into PAIRs that only partially displace the helix αC of IRE1α from an active conformation. The helix αCs of protein kinases are dynamic structural features that are often allosterically coupled to distal binding interfaces. In most cases the conformation of helix αC has been defined as two conformational extremes; an active “in” form or an inactive “out” conformation. PAIRs stabilize an intermediate conformational state between these two extremes, which appears to mimic unphosphorylated apo IRE1α based on the similar Kdimers of PAIR-bound IRE1α and unphosphorylated apo IRE1α. As the helix αCs of many kinases are components of binding interfaces, it is likely that similar rheostatic control can be engineered into ATP-competitive inhibitors that target other kinases
The capability to bifurcate the two distinct cytosolic RNase outputs of IRE1α with a small molecule opens up the potential to drug the UPR in more nuanced ways. Thus, we compared KIRAs and PAIRs here in two distinct—even opposite—cell fate outcome settings: one destructive (IRE1α over-expression leasing to apoptosis), the other constructive (B-cell differentiation). The dismantling of an ER-stressed cell during its commitment to entering mitochondrial apoptosis has been studied by us and others. We have proposed that hyperactivation of IRE1α RNase and reduction of many ER-localized mRNAs is a sine quo none of this cell death entry step. In many biological contexts, we have reported this RIDD signature preceding entry into apoptosis; this set of events is hastened in INS-1 insulinoma cell lines (derived from an insulin-producing β-cell tumor) that demonstrate RIDD (on top of XBP1 mRNA splicing) through mere overexpression of IRE1α. If RIDD leads deterministically to apoptosis, without regard to XBP1 outputs, PAIRs should be non-inferior to KIRAs in these cellular systems.
Indeed, we found using these systems, in which we could largely preserve XBP1 mRNA splicing with PAIR1, yet extinguishing it with KIRA9, that PAIRs perform equivalently to KIRAs. The transcriptome of downregulated messages is largely superimposable between PAIR1 and KIRA9 treatment in INS-1 cells as apoptotic gene upregulation is equivalently quelled in these cell destructive systems.
By comparison, in a model of de novo—constructive—differentiation of B-cells into immunoglobulin-producing plasma cells (induced by LPS), we observed differential effects between PAIR1 and KIRA9. By inhibiting XBP1 mRNA splicing (an event that has been shown to be required for building and expanding the ER physically and functionally during terminal differentiation), KIRA9 had potent dose-dependent inhibitory effects on production of CD-138+ plasma cells. However, PAIR1 was largely permissive for plasma cell differentiation, even at maximal kinase occupancy, while retaining XBP1 mRNA splicing. And as in the β-cell models, reduction of Blos1 mRNA (a RIDD target) was rescued with either compound.
In summary, we propose that the ability to segregate IRE1α's synthetic UPR outputs (i.e, XBP1 transcription factor-driven) from its destructive RIDD outputs through applying PAIRs as comparators to monomerizing KIRAs will reveal the scope and diversity of distinct UPR biological outputs. Finally, such compounds may have the benefit of navigating a wider therapeutic window than existing IRE1α kinase inhibitors (such as KIRAs or the less-selective RNase inhibitors that work through covalent modification). The unique ability of PAIRs to preserve adaptive XBP1 splicing at full target engagement may thereby achieve a more desirable therapeutic modulation of IRE1α in myriad diseases caused by ER stress-induced premature cell death.

Expression and Purification of IRE1α* and dP-IRE1α*
A construct containing the cytosolic kinase and RNase domains of human IRE1α (residues 547-977, IRE1α*) was expressed in SF9 insect cells by using the Bac-to-Bac baculovirus expression system (Invitrogen) with a His6 tag at the N-terminus and purified with a nickel-nitriloacetic acid (Qiagen) column. To generate dP-IRE1α*, we removed basal phosphorylation sites by incubating IRE1α* with λ-PPase (New England Biolabs) at a molar ratio of 5:1 (IRE1α*: λ-PPase) in 50 mM HEPES pH 7.5, 100 mM NaCl, 1 mM MnCl2, 2 mM dithiothreitol (DTT) and 0.01% Brij 35 detergent (v/v) overnight at 4° C. Dephosphorylation was verified through western blotting using a universal phospho-protein detection agent (biotin-pIMAGO (Tymora Analytical Operations, Cat. No.: FL800) and imaged using a streptavidin-linked fluorophore.
Western Blotting and Antibodies
For protein analysis, cells were lysed into modified RIPA buffer (50 mM Tris, 150 mM NaCl, 10 mM NaF, 1% NP40 (v/v), 0.25% sodium deoxycholate (w/v), 5% glycerol (v/v), pH 7.8) containing protease inhibitor (Pierce Protease Inhibitor Tablets and 1 mM PMSF) and phosphatase inhibitor (Phosphatase inhibitor cocktail 2 and 3, Sigma Aldrich) prior to gel loading. Western blots were performed using Any kD™ Mini-PROTEAN® TGX™ Precast protein gels (BioRad). Gels were ran using Tris-Glycine running buffer (25 mM Tris pH 8.6, 192 mM glycine, 0.1% SDS (w/v)) at 180 V. Gels were transferred to nitrocellulose paper using the TransBlot Turbo System (BioRad) at 25 V, 2.5 A for 15 minutes. Nitrocellulose blots were blocked for 30 minutes at room temperature with Odyssey blocking buffer (Li-Cor). Primary antibodies were diluted into blocking buffer and incubated over night at 4° C. Blots were washed 2× with TBST (20 mM Tris pH 7.5, 150 mM NaCl, 0.1% Tween-20) and incubated with near-infrared-dye-conjugated secondary antibodies (Li-Cor) for 1 hour at room temperature. Blots were imaged using a Li-Cor Odyssey IR Imager and quantitated using ImageStudio. The following primary antibodies were used in this study: rabbit anti-IRE1α mAb #14C10 (Cell Signaling, no. 3294), mouse anti-FLAG (DYKDDDDK (SEQ ID NO:24) mAb (Sigma Aldrich, no. F3165), rabbit anti-spliced XBP1 (Cell Signaling, no. 12782), rabbit anti-caspase 3 (Cell Signaling, no. 9662), rabbit anti-cleaved caspase 3 (Cell Signaling, no. 9661), mouse anti-proinsulin (Santa Cruz Biotechnology, no. sc-9168), and rabbit anti-GAPDH (Santa Cruz Biotechnology, no. sc-25778).
In Vitro Kinase Activity Assay
Inhibitors (initial concentration of 10 or 60 μM, three-fold serial dilutions) were incubated with IRE1α* in cleavage buffer (20 mM HEPES, 0.05% Triton X-100 (v/v), 50 mM KCl, 1 mM MgCl2, 1 mM DTT, pH 7.5) for 30 min, followed by incubation with 10 μCi [γ32P] ATP (3,000 Ci mmol−1, PerkinElmer) at 23° C. for 3 hours. Samples were then spotted onto glass fiber paper (Easytab-C Glass Fiber Filter Paper, Perkin Elmer) and washed in twice with 0.5% phosphoric acid and autoradiographed using a GE Typhoon FLA 9000 Imager. Blots were quantitated using ImageQuant software. The percent inhibition was quantified by setting the background (no kinase well) as 0 and standardizing to IRE1α* without compound treatment (IRE1α*+DMSO). Dose-response curves were fit using “one-site fit log IC50” parameter using GraphPad Prism analysis software.
In Vitro RNase Activity Assay Inhibitor Titrations
50 nM IRE1α* was incubated with inhibitor (initial concentration of 10 or 60 μM, three-fold serial dilutions) or DMSO for 30 min in assay buffer (20 mM Tris, 50 mM NaCl, 1 mM MgCl2, 2 mM DTT, 0.05% Triton X-100 (v/v), pH 7.5). Assays were initiated by adding 10 μL of XBP1-mini substrate (5′-Alex647-CAUGUCCGCAGCGCAUG-IowaBlack-FQ-3′ (SEQ ID NO: 1); IDT) to the wells at a final concentration of 200 nM and a final well volume of 30 μL. Fluorescence was detected on a Perkin Elmer Envision Microplate Reader at excitation and emission wavelengths of 650 nm and 665 nm. Dose-response curves were fit using “one-site fit log IC50” parameter using GraphPad Prism analysis software.
In Vitro Kdimer Assay
IRE1α* or dPIRE1α* was titrated from either 2 μM or 4 μM in two-fold serial dilutions in assay buffer (20 mM Tris, 50 mM sodium chloride, 1 mM MgCl2, 2 mM DTT, 0.05% Triton X-100 (v/v), pH 7.5) and incubated with 50 μM inhibitor for 30 minutes at room temperature. Assays were initiated by adding 10 μL of XBP1-mini substrate (5′-Alex647-CAUGUCCGCAGCGCAUG-IowaBlack-FQ-3′ (SEQ ID NO:1); IDT) to the wells at a final concentration of 6 μM and a final well volume of 30 μL. Fluorescence was detected on a Perkin Elmer Envision Microplate Reader at excitation and emission wavelengths of 650 nm and 665 nm. Reaction process was monitored real time in 10-second intervals for at least 30 minutes. Initial rates of XBP1-cleavage were determined for each respective IRE1α* of dpIRE1α* concentration. Specific activity was then determined by dividing rate (RFU/s) by the respective IRE1α* of dpIRE1α* used (RFU/s*[IRE1α]). Kdimer values were determined by fitting these values using the non-linear regression ‘one-site total’ binding parameter in GraphPad Prism analysis software.
Crystallization of IRE1α*+PAIR1
Protein Production and Crystallization
Expression of IRE1α was performed according to previously established protocols. A purification protocol was established and homogeneous protein was produced in preparative amounts. The protein was purified comprising affinity and gel filtration chromatography steps. This procedure yielded homogenous protein with a purity greater 95% as judged from Coomassie stained SDS-PAGE. The purified protein was used in crystallization trials employing both, a standard screen with approximately 1200 different conditions, as well as crystallization conditions identified using literature data. Conditions initially obtained have been optimized using standard strategies, systematically varying parameters critically influencing crystallization, such as temperature, protein concentration, drop ratio, and others. These conditions were also refined by systematically varying pH or precipitant concentrations.
Data Collection and Processing
A cryo-protocol was established using PROTEROS Standard Protocols. Crystals have been flash-frozen and measured at a temperature of 100 K. The X-ray diffraction data have been collected from complex crystals of IRE1α with the ligand PAIR1 at the SWISS LIGHT SOURCE (SLS, Villigen, Switzerland) using cryogenic conditions. X-ray source was PXII/X10SA and wavelength was 1.0000 Å. The crystals belong to space group C 2. Data were processed using the programs: XDS and XSCALE.
Structural Modeling and Refinement
The phase information necessary to determine and analyze the structure was obtained by molecular replacement. A previously solved structure of IRE1α was used as a search model. Subsequent model building and refinement was performed according to standard protocols with the software packages CCP4 and COOT. For the calculation of the free R-factor, a measure to cross-validate the correctness of the final model, about 2.6% of measured reflections were excluded from the refinement procedure (see Table 1). TLS refinement (using REFMAC5, CCP4) has been carried out, which resulted in lower R-factors and higher quality of the electron density map. Automatically generated local NCS restraints have been applied (keyword “ncsr local” of newer REFMAC5 versions). The ligand parameterization and generation of the corresponding library files were carried out with CORINA. The water model was built with the “Find waters” algorithm of COOT by putting water molecules in peaks of the Fo-Fc map contoured at 3.0 followed by refinement with REFMAC5 and checking all waters with the validation tool of COOT. The criteria for the list of suspicious waters were: B-factor greater 80 Å2, 2Fo-Fc map less than 1.2σ, distance to closest contact less than 2.3 Å or more than 3.5 Å. The suspicious water molecules and those in the ligand binding site (distance to ligand less than 10 Å) were checked manually. The Ramachandran Plot of the final model shows 92.6% of all residues in the most favored region, 6.7% in the additionally allowed region, and 0.4% in the generously allowed region. The residues Met872(A) and Met872(B) are found in the disallowed region of the Ramachandran plot. They are either confirmed by the electron density map or could not be modelled in another sensible conformation.

Kinome Profiling and Selectivity
Kinobead Enrichment Protocol
HEK293 and HCT116 cells were plated on 15 cm plates until 90% confluent and lysed into 750 μL modified RIPA buffer (50 mM Tris, 150 mM NaCl, 10 mM NaF, 1% NP40, 0.25% sodium deoxycholate, 5% glycerol, pH 7.8) containing protease inhibitor (Pierce Protease Inhibitor Tablets and 1 mM PMSF) and phosphatase inhibitor (Phosphatase inhibitor cocktail 2 and 3, Sigma Aldrich). Protein content was determined via Bradford assay. HEK293 and HCT116 lysates were combined in a 1:1 ratio and exogenous IRE1α* was added to the lysate at a final concentration of 33.3 nM. Lysate (300 μg per sample) was incubated and rotated end over end with 10 μM inhibitor or DMSO (1% v/v) for 1 hour at 4° C. For kinase enrichment, 10 μL of 50% kinobead slurry (in 20% ethanol) was prepared by washing twice with 500 μL Mod. RIPA buffer. DMSO or inhibitor treated lysates were then added to the washed kinobeads and rotated end over end for 3 hours at 4° C. After enrichment, the supernatant was aspirated off and the beads were washed twice with 500 μL ice cold Mod. RIPA buffer and three times with 500 μL ice cold TBS (50 mM Tris, 150 mM NaCl, pH 7.8) to remove detergent. Beads were resuspended in 25 μL of denaturing buffer (6M guanidinium chloride, 50 mM Tris containing 5 mM TCEP and 10 mM CAM, pH 8.5). The bead slurries in denaturing buffer were then heated to 95° C. for 5 min. After, the bead slurries were diluted 2-fold (add 25 μL) with 100 mM TEAB (triethylammonium bicarbonate buffer, pH 8.5). Then 0.4 μg of LysC (Wako) were added to the beads and the pH adjusted to 8-9 with 1 N NaOH. The mixture was agitated on a Thermomixer (Eppendorf) at 37° C. for 2 hr at 1400 rmp. After, the samples were diluted 2-fold (50 μL) with 100 mM TEAB and 0.4 μg of sequencing grade trypsin (Pierce) was added and the samples agitated for another 12 hr at 37° C. at 800 rpm in the Thermomixer. After the overnight trypsinization, samples were diluted 2-fold (100 μL) with Buffer A (5% ACN, 0.1% TFA) containing 1% formic acid and the pH adjusted to 2-3 with formic acid if necessary. Homemade StageTips were prepared by running 50 μL of Buffer B (80% ACN, 0.1% TFA, H2O) through them followed by 50 μL of Buffer A (5% ACN, 0.1% TFA, H2O).92 Beads were spun down and supernatant was added directly to StageTips. Following sample loading, StageTips were washed with 50 μL of Buffer A and eluted with 50 μL Buffer B. Samples were speed vacuumed until dry and re-suspend in Buffer A for injection onto LC-MS.79
LC-MS and Data Analysis
Tryptic peptides were separated using a nanoAcquity UPLC instrument with 10 cm fused silica capillary columns made in house and packed with 5 μm 120 Å reverse-phase C18 beads (ReproSil-Pur®, Maisch). Liquid chromatography was performed over 120 minutes using and initial 20 minute isocratic trapping of 3% Buffer B and a flow rate of 700 nL/min followed by a 100 minute gradient of 35% Buffer B to 80% Buffer B gradient at 350 nL/min. LC Buffer A solvent is 0.1% acetic acid and LC Buffer B is 99.9% ACN, 0.1% acetic acid. MS data was analyzed using a Thermo Orbitrap Fusion Tribrid. Raw files were analyzed using MaxQuant (Andromeda) Version 1.6.0.16. Files were analyzed further using Perseus (Version 1.6.0.7) by filtering LFQ intensity values only identified by site, reverse, or potential contaminant. Missing LFQ intensity values were imputed in Perseus from a standard distribution downshifted by 1.8 and having a width of 0.4. To determine kinases that were significantly competed by treatment with 10 μM of inhibitor we applied a two-tailed two-sample t-test in Perseus with an FDR of 0.05. Kinases were reported as being non-competed by an inhibitor if it had a Log2 LFQ ratio (Log2 Difference)<1.0. Kinome tree visualization plots were created using CORAL and heat maps were made using GraphPad Prism V.B.
Phostag Acrylamide Gels
Treatment Conditions for Phostag Gels
INS-1 or IRE1α-overexpressing isogenic INS-1 cells were plated onto a 24-well Poly-D-Lysine coated tissue culture plate and grown for 48 hrs. Inhibitor or DMSO were added to the media and incubated for 1 hour at 37° C. with 5% CO2 prior to addition of ER stress agents. After the 1 hour inhibitor incubation, cells were treated 200 μg/mL BFA (Sigma, Prod. No.: B6542) for 2 hours or 5 ng/mL doxycycline (Sigma) for 6 hours, with care to ensure the total DMSO concentration in the media did not exceed 1% (v/v). Cells were lysed directly into SDS loading buffer (50 mM Tris, 100 mM DTT, 2% SDS (w/v), 10% glycerol (v/v), and 0.1% bromophenol blue (w/v), pH 6.8) and boiled for five minutes prior to gel loading.
Phostag Acrylamide Gel Procedure
A phostag acrylamide gel recipe used to resolve phosphorylation of IRE1α has been previously established and this recipe was followed verbatim for this study.91 Resolving gels were allowed to solidify (˜1.5 hr) before adding the stacking gel and comb and allowed to solidify (˜1 hr). Gels were run using Tris-Glycine-SDS running buffer (25 mM Tris, 192 mM glycine, 0.1% SDS, pH 8.3) at 100 V for 3-3.5 hours. After the gels have ran, they were transferred onto nitrocellulose paper via rapid transfer using a Transblot Turbo and premade transfer packs. Gels were transferred at 25 V, 2.5 A for 15 minutes. Once transferred onto nitrocellulose, proceed with western blotting procedure as normal.
Tissue Culture
INS-1s (rat insulinoma beta cells) were grown in RPMI, 10% FBS buffer (v/v), 1 mM sodium pyruvate, 10 mM HEPES, 2 mM glutamine and 50 μM β-mercaptoethanol on Poly-D-Lysine coated tissue culture flasks. IRE1α (murine) was cloned into a pcDNA5/FRT/TO. INS-1 FRT/TO cells were grown following the protocol above. INS-1 FRT/TO cells were transfected with 2 μg IRE1α-pcDNA5/FRT/TO and 2 μg pOG44 using Lipofectamine 2000 (Thermo Fisher). Cell media was exchanged the next day and cells were allowed grow for another day before passaging. Selection was performed using 50 μg/mL Hygromycin-B (Thermo Fisher) over about two weeks until all un-transfected cells have died and colonies have appeared in transfected cells. Stably integrated cells were maintained in RPMI, 10% FBS buffer (v/v), 1 mM sodium pyruvate, 10 mM HEPES, 2 mM glutamine and 50 μM β-mercaptoethanol, 25 μg/mL Hygromycin-B. HEK293 cells were grown in DMEM High Glucose media (Gibco) supplemented with 10% FBS. HCT-116 cells were maintained in McCoy's 5A modified media (Gibco) supplemented with 10% FBS. All cells lines were maintained at 37° C. with 5% CO2.
RNA Isolation, Quantitative Real-Time PCR, and Primers
INS-1 or isogenic IRE1α-overexpressing INS-1 cells were plated onto Poly-D-Lysine coated tissue culture plate and grown for 48 hrs. Inhibitors or DMSO were added to the media and incubated for 1 hour at 37° C. with 5% CO2 prior to addition of ER stress agents or Dox as indicated. RNA was isolated from whole cells using either QIAGEN RNeasy Mini kits or Trizol (Invitrogen) and reverse transcribed as above to obtain total cDNA. Then, XBP-1 primers were used to amplify an XBP-1 amplicon spanning the 26 nt intron from the cDNA samples in a regular 3-step PCR. Thermal cycles were: 5 min at 95° C., 30 cycles of 30 s at 95° C., 30 s at 60° C., and 1 min at 72° C., followed by 72° C. for 15 min, and hold at 4° C. Primers used for XBP-1 mRNA splicing were as follows: sense primer XBP1.3 S (5′ AAACAGAGTAGCACAGACTGC-3′ (SEQ ID NO:2)) and antisense primer XBP1.2AS (5′-GGATCTCTAAGACTAGAGGCTTGGTG-3′ (SEQ ID NO:3)). PCR fragments were then digested by PstI, resolved on 3% agarose gels, stained with EtBr and quantified by densitometry using ImageJ (NIH). For standard mRNA detection, generally 1 mg total RNA was reverse transcribed using the QuantiTect Reverse Transcription Kit (QIAGEN). For qPCR, we used SYBR green (QIAGEN) and StepOnePlus Real-Time PCR System (Applied Biosystems). Thermal cycles were: 5 min at 95° C., 40 cycles of 15 sec at 95° C., 30 sec at 60° C. Gene expression levels were normalized to Beta Actin. Primers used for qPCR of RIDD targets were as follows: Beta Actin Fwd: 5′-GCAAATGCTTCTAGGCGGAC-3′ (SEQ ID NO:4), Beta Actin Rev: 5′-AAGAAAGGGTGTAAAACGCAGC-3′ (SEQ ID NO:5), Insulin 1 Fwd: 5′-GTCCTCTGGGAGCCCAAG-3′ (SEQ ID NO:6), Insulin 1 Rev: 5′-ACAGAGCCTCCACCAGG-3′ (SEQ ID NO:7), Insulin 2 Fwd: 5′-ATCCTCTGGGAGCCCCGC-3′ (SEQ ID NO:8), Insulin 2 Rev: 5′-AGAGAGCTTCCACCAAG-3′ (SEQ ID NO:9), Blos1 Fwd: 5′-CAAGGAGCTGCAGGAGAAGA-3′ (SEQ ID NO:10), and Blos1 Rev: 5′-GCCTGGTTGAAGTTCTCCAC-3′ (SEQ ID NO:11).
Annexin-V Staining
For assaying apoptosis by Annexin V staining, cells were plated in 12-well plates overnight. Cells were then treated with various reagents for indicated time periods. On the day of flow cytometry analysis, cells were trypsinized and washed in PBS and resuspended in Annexin V binding buffer with Annexin-V FITC (BD Pharmingen™). Flow cytometry was performed on a Becton Dickinson LSRII flow cytometer.
Ex Vivo Islet Studies and Glucose Stimulated Insulin Secretion
Non-diabetic human islets were obtained and cultured in supplemented Prodo Islet Medium (PIM(S) from Prodo Labs). Islets were pretreated with either DMSO, PAIR1, or KIRA9 for 2 hrs followed by treatment with 0.5 μg/mL tunicamycin for 16 hours. Approximately 50 islets were cultured for each condition in triplicate. PAIR1 or KIRA9 (20 μM) was added 2 hr before treating with Tm. In the GSIS assay, islets were preincubated in HEPES-buffered Krebs-Ringer bicarbonate solution (KRBH) (10 mM HEPES, 129 mM NaCl, 4.7 mM KCl, 1.2 mM KH2PO4, 1.2 mM MgSO4, 2 mM CaCl2, 5 mM NaHCO3, 0.1% BSA, pH 7.4) containing 2.5 mM glucose for 30 min at 37° C. Fifty islets per condition were incubated with either 2.5 mM or 16.7 mM glucose in KRBH at 37° C. for 30 min. Collected media were analyzed by anti-insulin ELISA (EMD Millipore) and insulin levels were normalized to total protein amount.
RNA Sequencing
RNA Isolation and Preparation
Isogenic IRE1α-overexpressing INS-1 cells were pre-treated with inhibitors for 1 h followed by addition of Dox 5 ng/mL for 4 h and 24 h as indicated. All conditions for RNAseq analysis were performed in three biological replicates. RNA was isolated from whole cells using Qiagen RNeasy with gDNA eliminator kit. RNA purity was determined using a NanaPhotometer spectrometer (IMPLEN, CA, USA). RNA integrity and quantitation were assessed using the RNA Nano 6000 Assay Kit of the Bioanalyzer 2100 system (Agilent Technologies, CA, USA).
Library Preparation
Library preparation for RNAseq was performed by Novogene. A total amount of 1 RNA per sample was used as input material for the RNA sample preparations. Sequencing libraries were generated using NEBNext® Ultra™ RNA Library Prep Kit for Illumina® (NEB, USA) following manufacturer's recommendations and index codes were added to attribute sequences to each sample. Briefly, mRNA was purified from total RNA using poly-T oligo-attached magnetic beads. Fragmentation was carried out using divalent cations under elevated temperature in NEBNext First Strand Synthesis Reaction Buffer (5×). First strand cDNA was synthesized using random hexamer primer and MMuLV Reverse Transcriptase (RNase H). Second strand cDNA synthesis was subsequently performed using DNA Polymerase I and RNase H. Remaining overhangs were converted into blunt ends via exonuclease/polymerase activities. After adenylation of 3′ ends of DNA fragments, NEBNext Adaptor with hairpin loop structure were ligated to prepare for hybridization. In order to select cDNA fragments of preferentially 150-200 bp in length, the library fragments were purified with AMPure XP system (Beckman Coulter, Beverly, USA). Then 3 USER Enzyme (NEB, USA) was used with size-selected, adaptor-ligated cDNA at 37° C. for 15 min followed by 5 min at 95° C. before PCR. Then PCR was performed with Phusion High-Fidelity DNA polymerase, Universal PCR primers and Index (X) Primer. At last, PCR products were purified (AMPure XP system) and library quality was assessed on the Agilent Bioanalyzer 2100 system.
Clustering and Sequencing
The clustering of the index-coded samples was performed on a cBot Cluster Generation System using PE Cluster Kit cBot-HS (Illumina) according to the manufacturer's instructions. After cluster generation, the library preparations were sequenced on an Illumina platform and 125 bp/150 bp paired-end reads were generated.
Quality Control and Genome Mapping
Raw data (raw reads) of fastq format were firstly processed using Novogene perl scripts. In this step, clean data (clean reads) were obtained by removing reads containing adapter, reads containing ploy-N and low quality reads from raw data. At the same time, Q20, Q30 and GC content the clean data were calculated. All the downstream analyses were based on the clean data with high quality. Reference genome and gene model annotation files were downloaded from genome website directly. Index of the reference genome was built using hisat2 2.1.0 and paired-end clean reads were aligned to the reference genome using HISAT2.
Quantification of Gene Expression Level
HTSeq v0.6.1 was used to count the reads numbers mapped to each gene. And then FPKM of each gene was calculated based on the length of the gene and reads count mapped to this gene. FPKM, expected number of Fragments Per Kilobase of transcript sequence per millions base pairs sequenced, considers the effect of sequencing depth and gene length for the reads count at the same time, and is currently the most commonly used method for estimating gene expression levels (Trapnell, C. et al. (2010). Transcript assembly and quantification by RNA-seq reveals unannotated transcripts and isoform switching during cell differentiation. Nat. Biotechnol.).
Differential Expression Analysis
Differential expression analysis of two conditions/groups (three biological replicates per condition) was performed using the DESeq R package (1.18.0). DESeq provide statistical routines for determining differential expression in digital gene expression data using a model based on the negative binomial distribution. The resulting P-values were adjusted using the Benjamini and Hochberg's approach for controlling the false discovery rate. Genes with an adjusted P-value<0.05 found by DESeq were assigned as differentially expressed.
GO and KEGG Enrichment Analysis of Differentially Expressed Genes
Gene Ontology (GO) enrichment analysis of differentially expressed genes was implemented by the GOseq R package, in which gene length bias was corrected. GO terms with corrected P-value less than 0.05 were considered significantly enriched by differential expressed genes. KEGG is a database resource for understanding high-level functions and utilities of the biological system, such as the cell, the organism and the ecosystem, from molecular-level information, especially large-scale molecular datasets generated by genome sequencing and other high-through put experimental technologies (http://www.genome.jp/kegg/). We used KOBAS software to test the statistical enrichment of differential expression genes in KEGG pathways.
Splenocyte Isolation and Differentiation
Splenocytes were isolated from a C57BL/6 mouse into single cell suspension in complete media: RPMI 1640, L-glutamine (Corning-Gibco), penicillin/streptomycin L-glutamine (Life Technologies), 10 mM HEPES buffer (Life Technologies), non-essential amino acids (Life Technologies), 1 mM sodium pyruvate (Life Technologies), 55 mM 2-mercaptoethanol (Gibco), and 10% heat inactivated fetal bovine serum (Omega Scientific). Red blood cells were lysed with ammonium chloride potassium buffer. Splenocytes were plated at 2.5×105 cells/well in a 96-well round bottom plate in complete media. The splenocytes were treated with or without 1 μg/ml LPS 026:b6 (Sigma). Two-fold serial dilutions of IRE1α inhibitors (20 μM-1.25 μM) were prepared in DMSO and added to the LPS treated cells at a final dilution of 1:1000. The splenocytes were incubated for three days in a 37° C., 5% CO2 humidified chamber before collection and staining for flow cytometry.
Flow Cytometry
Cells from the plasma cell assay were collected in a 96-well plate and washed with PBS followed by staining with LIVE/DEAD Fixable Near-IR Dead Cell Stain kit (Invitrogen). Reagent was reconstituted as per manufacturer's instructions, diluted 1:1000 in PBS, and cells were stained in 100 μL on ice for 20 minutes. The cells were then washed with FACS buffer, PBS (Corning), 2 mM EDTA and 2% heat inactivated fetal bovine serum (Omega Scientific). The cells were then stained with 50 μL antibody cocktail consisting of anti-CD19 (BioLegend), anti-CD45R (BD Pharmingen), and anti-CD138 (BioLegend) in FACS buffer on ice for 15 minutes. Cells were resuspended in FACS buffer and combined with an equal volume of 4% paraformaldehyde with 5000 Countbright Absolute Counting Beads (Thermofisher). Stained cells were analyzed on a Fortessa (Becton Dickinson). Data analysis was performed using FlowJo (v10) software (Treestar Inc.).
ELISA for Secreted IgM
Media supernatants from the in vitro plasma cell differentiation assay were measured for secreted IgM by ELISA. 96-well plates (Costar, #3690) were coated with 1 μg/ml goat anti-IgM (Southern Biotech, #1020-01) in PBS. Wash buffer (PBS with 0.05% Tween-20 (v/v)) was used for all washing steps and blocked with PBS-BB (PBS without Ca2+/Mg2+, 1% BSA (w/v), 0.05% Tween-20 (v/v)). Supernatants from LPS stimulated samples were diluted (1:100) and media only samples were diluted (1:10) in PBS-BB. IgM standard (Southern Biotech, #0101-01) was prepared in a 2-fold serial dilution in PBS-BB. IgM was detected with Goat anti-IgM-HRP (Southern Biotech, #1020-05) diluted (1:3000) in PBS-BB. ELISA plates were developed with TMB (Sigma) and stopped with 1N sulfuric acid. Absorbance was measured at 450 nm using spectrophotometer (Spectramax M5, Molecular Devices). Sample IgM concentration values were calculated with SoftMaxPro software.
XBP1 Splicing
RNA was extracted using Trizol (Invitrogen), DNaseI treated, and cDNA products encompassing the intron amplified by QuantiTect Reverse Transcription Kit (Qiagen). sense Primer rXBP Forward (5′-TGAAAAACAGAGTAGCAGCACAGA-3′ (SEQ ID NO:12)) and antisense primer rXBP Reverse (5′-AAGGGAGGCTGGTAAGGAAC-3′ (SEQ ID NO:13)) were used. PCR fragments were digested by PstI, resolved on 3% agarose gels, stained with EtBr, and quantified by densitometry.
XBP1 splicing for
Real-Time PCR
Real-Time PCR (Q-PCR) used SYBR green and Step OnePlus Real-Time PCR System (Applied Biosystems). Thermal cycles were: 5 min at 95° C., 40 cycles of 15 s at 95° C., 30 s at 60° C. Gene expression levels were normalized to GAPDH. Q-PCR Sense/antisense primers used: Rat GAPDH, 5′-AGTTCAACGGCACAGTCAAG-3′ (SEQ ID NO:14) and 5′-TACTCAGCACCAGCATCACC-3′ (SEQ ID NO:15); Rat Ins1, 5′-GTCCTCTGGGAGCCCAAG-3′ (SEQ ID NO:6) and 5′-ACAGAGCCTCCACCAGG-3′ (SEQ ID NO:7); Rat Pdia4, 5′-CGTCTCGCCCTGATTCGT-3′ (SEQ ID NO:16) and 5′-GGAAGTTCAGCCCGGTGATT-3′ (SEQ ID NO:17); Rat Blos1, 5′-TGGATTGGCATGGTGGAAAAC-3′ (SEQ ID NO:18) and 5′-TGTCCAGTTCGATGCTCCG-3′ (SEQ ID NO:19).
