Interleukin-6 (IL-6) is a cytokine produced by a large variety of cell types and can exert its effects on virtually all cells. IL-6 is involved in a broad array of biological activities such as immune responses, apoptosis, and proliferation [Kishimoto T, Akira S, Taga T. Interleukin-6 and its receptor: a paradigm for cytokines. Science 1992, 258, 593-597]. However, when IL-6 is dysregulated or constantly expressed at a high level, it will cause numerous pathological conditions (
IL-6 was first identified by its ability to activate the maturation of B cells to antibody-secreting plasma cells [Okada M. B cell growth factors and B cell differentiation factor from human T hybridomas. Two distinct kinds of B cell growth factor and their synergism in B cell proliferation. J Exp Med 1983, 157, 583-590]. It has been referred to by several names such as B-cell stimulatory factor-2 (BCSF-2), interferon-2 (IFN-2), hepatocyte stimulating factor (HSF), macrophage granulocyte inducer type 2 (MGI-2A) or thrombopoietin [Kishimoto T. The biology of interleukin-6. Blood 1989, 74, 1-10], which also illustrates its versatile functions. A 1.9 Å crystal structure of IL-6 was reported by Somers and his coworkers in 1997 [Somers W, Stahl M, Seehra, J. 1.9 Å crystal structure of interleukin 6: implications for a novel mode of receptor dimerization and signaling. The EMBO Journal 1997, 16, 989-997; Xu G-Y, Yu H-A, Hong J, et al. Solution structure of recombinant human interleukin-6. J Mol Biol 1997, 268, 468-481]. It is a 26-kDa glycoprotein that contains 212 amino acids arranged in a five helix bundle, with four of them forming a classical four-helix bundle with a conformation termed “up-up-down-down” [Zaccaro L, Bucci E, Vitale M, et al. Synthetic peptides mimicking the interleukin-6/gp 130 interaction: a two-helix bundle system. Design and conformational studies. J Pept Sci. 2003, 9, 90-105; Boulanger M J, Chow D C, Brevnova E E, et al. Hexameric structure and assembly of the interleukin-6/IL-6 alpha-receptor/gp130 complex. Science 2003, 300, 2101-2104].
Il-6 activates a cell surface signaling assembly composed of IL-6, the IL-6 α-receptor (IL-6Ra), and the shared signaling receptor gp130. IL-6 first binds to IL-6Ra to form a binary complex, then recruits gp130 to form the IL-6/IL-6Ra/gp130heterotrimer. Furthermore, homodimerization of the IL-6/IL-6Ra/gp130 heterotrimer occurs by interactions between IL-6 of one trimer and the D1 domain of gp130 of the other trimer, forming a hexamer [Boulanger M J, Chow D C, Brevnova E E, et al. Hexameric structure and assembly of the interleukin-6/IL-6 alpha-receptor/gp130 complex. Science 2003, 300, 2101-2104; Eric A, Marie-Christophe B, Jean-Michel D. Interleukin-6: From identification of the cytokine to development of targeted treatments. Joint Bone Spine 2010, 77, 532-536]. The reciprocal homodimerization of the IL-6/IL-6Ra/gp130 trimer triggers the activation of associated Janus kinase (JAK). Then, JAK causes autophosphorylation as well as the phosphorylation of gp130. After that, the phosphorylated positions on JAK and gp130 serve as the docking sites of downstream effector signal transducer and activator of transcription 3 (STAT3) SH2 domain, followed by reciprocal dimerization of phosphorylated STAT3, nuclear translocation, DNA binding and cancer gene transcription [Darnell J E. STATs and gene regulation. Science, 1997, 277, 1630-1635; Jinxia D, Fedora G, Nouri N. Small Molecule Inhibitors of Stat3 Signaling Pathway. Curr Cancer Drug Targets, 2007, 7, 91-107]. Other than the IL-6/gp130/STAT3 signaling pathway, IL-6 can also activate the PI3K/AKT pathway and the Raf/MEK/ERK pathway. The existence of these different pathways activated by IL-6 appears to be highly cell type-dependent [Haegeman G. Structural analysis of the sequence coding for an inducible 26-kDa protein in human fibroblasts. Eur J Biochem 1986, 159, 625-632; Yamasaki K. Cloning and expression of the human interleukin-6 (BSF-2/IFN beta 2) receptor. Science 1988, 241, 825-828].
The extracellular structure and assembly of the IL-6/IL-6Ra/gp130complex was solved in 2003 by the Garcia group [Boulanger M J, Chow D C, Brevnova E E, et al. Hexameric structure and assembly of the interleukin-6/IL-6 alpha-receptor/gp130 complex. Science 2003, 300, 2101-2104], and the full-length transmembrane IL-6/IL-6Ra/gp130 cytokine receptor complex was solved by the same group in 2011 [Patrick J, Georgios S, Amanda J, et al. structural snapshots of full-length Jak1, a transmembranegp130/IL-6/IL-6Ra cytokine receptor complex, and the receptor-Jak1 holocomplex. Structure 2011, 19, 45-55]. The IL-6 extracellular signaling portion is a symmetric hexamer, which contains two IL-6, two IL-Ra and two gp130 subunits assembling sequentially and cooperatively. There are five main binding epitopes involved in this complex, namely site I, site II (IIa and IIb) and site III (IIIa and IIIb). [Boulanger M J, Chow D C, Brevnova E E, et al. Hexameric structure and assembly of the interleukin-6/IL-6 alpha-receptor/gp130 complex. Science 2003, 300, 2101-2104].
Site I is formed when IL-6 binds to IL-6Ra. Binding occurs between the D3 domain of IL-6Ra and the A and D helices of IL-6. It covers an area of 1200 Å2. The key residues in this binding site are Phe229 and Phe279 on the IL-6Ra D3 domain, Arg179 and Lys171 on IL-6. Site II is formed when the IL-6/IL-6Ra complex binds to gp130. Site IIa consists of the elbow region of D2 and D3 on gp130 and the A and C helices on IL-6. It covers an area of 1272 Å2, where Phe169 on the gp130 elbow region and Arg24, Lys27, Arg30 and Asp34 contribute the most to the binding surface. Site IIb consists of the D3 domain on IL-6Ra and the D3 domain on gp130, which covers a surface area of 1078 Å2. Site III is formed when two IL-6/IL-6Ra/gp130 trimers dimerize with each other. Site IIIa consists of the tip of the IL-6 four-helix bundle and the bottom R sheet of the D1 domain of gp130, which covers an area of 1276 Å2. The N-terminal peptide of gp130 (from Leu2 to Cys6) is solvent-exposed and inserts in a groove on the surface of IL-6 formed by the A, B and C, D inter-helical loops. Trp157 on IL-6 is also found to be critical, contributing 21% of the total buried surface area. This finding is consistent with previous results obtained through mutagenesis that this aromatic signature residue is of great importance in Site IIIa [Paonessa G. Graziani R, De S A, et al. Two distinct and independent sites on IL-6 trigger gp 130 dimer formation and signaling. EMBO J 1995, 14, 1942-1951; Barton V A, Hudson K R, Heath J K. Identification of Three Distinct Receptor Binding Sites of Murine Interleukin-11. J Biol Chem 1999, 274, 5755-5761]. Site IIIb involves the interaction between the tip of D1 domain on gp130 and the D2 domain of IL-6Ra, which covers a surface area of 473 Å2.
Other than IL-6, there are seven other members in the IL-6 family of cytokines, which are IL-11, leukemia inhibitory factor (LIF), oncostatin M (OSM), cardiotrophin-1 (CT-1), ciliary neurotrophic factor (CNTF), cardiotrophin-like cytokine (CLC) and IL-27 [Ursula A W, Jacqueline M S. The gp130 Receptor Cytokine Family: Regulators of Adipocyte Development and Function. Curr Pharm Des. 2011, 4, 340-346]. They are grouped together because all of these cytokines require the signal receptor subunit gp130 in the signal transduction process, so they are also referred to as gp130 related cytokines. These cytokines act in a pleiotropic manner, and are also redundant in regulating various biological processes [Ernst M, Jenkins B J. Acquiring signalling specificity from the cytokine receptor gp130. Trends in genetics 2004, 20, 23-32]. The IL-6 family of cytokines participate in signal transduction mainly through the JAK/STAT pathway and the most common STAT activated is STAT3 [Heinrich P C, Behrmann I, Haan S, et al. Principles of interleukin (IL)-6-type cytokine signalling and its regulation. Biochem J 2003, 374, 1-20].
As mentioned above, as all members in the IL-6 family of cytokines transduce their signals through glycoprotein 130 (gp130), they still require other receptors to form the signal transduction complex and the stoichiometry varies. For IL-6 and IL-11, both initially bind to the IL-6 receptor a or IL-11 receptor a [White U A, Stewart W C, Mynatt R L, et al. Neuropoietin attenuates adipogenesis and induces insulin resistance in adipocytes. J Biol Chem 2008, 283, 22505-22512], respectively. The dimer then recruits and associates with gp130 to form a trimer, followed by homodimerization of two of these trimers for signal transduction. For LIF and CT-1, both require the LIF receptor (LIFR) to form a complex with gp130 to mediate signal transduction [Gearing D P, Thut C J, VandeBos T, et al. Leukemia inhibitory factor receptor is structurally related to the IL-6 signal transducer, gp130. EMBO J 1991, 10, 2839-2848; Pennica D, Shaw KJ, Swanson T A, et al. Cardiotrophin-1. Biological activities and binding to the leukemia inhibitory factor receptor/gp130 signaling complex. J Biol Chem 1995, 270, 10915-10922]. In addition to LIFR, CT-1 has also been reported to recruit another as yet unidentified alpha receptor [Robledo O, Guillet C, Chevalier S, et al. Hepatocyte-derived cell lines express a functional receptor for cardiotrophin-1. Eur Cytokine Netw 1997, 8, 245-52]. For CNTF and CLC, both require CNTFRa and LIFR to form a complex with gp130 for signal transduction [Davis S, Aldrich T H, Stahl N, et al. LIFR beta and gp130 as heterodimerizing signal transducers of the tripartite CNTF receptor. Science 1993, 260, 1805-1808; Elson G C, Lelievre E, Guillet C, et al. CLF associates with CLC to form a functional heteromeric ligand for the CNTF receptor complex. Nat Neurosci 2000, 3, 867-872]. For OSM, it has been reported to either utilize the LIFR complex or alternatively utilize an OSM receptor (OSMR) to form a complex with gp130 during signaling [Ichihara M, Hara T, Kim H, et al. Oncostatin M and leukemia inhibitory factor do not use the same functional receptor in mice. Blood 1997, 90,165-173], although some studies indicate that OSM primarily signals via the OSMR and not the LIFR. For IL-27, its cell signaling engages a gp130/WSX-1 heterodimeric receptor complex [Pflanz S, Hibbert L, Mattson J, et al. WSX-1 and glycoprotein 130 constitute a signal-transducing receptor for IL-27. J Immunol 2004, 172, 2225-2231].
From this discussion, it is apparent that IL-6 and IL-11 signal transduction require the dimerization of two gp130 subunits, while in signaling by other IL-6 family members, only one gp130 is involved. As a result, the binding site III in IL-6 signaling is unique from LIF, CNTF, CLC, CT-1, OSM and IL-27. It may share some similarity with IL-11 signaling, although the complex crystal structure of this signaling complex remains unknown.
IL-6 was first discovered as an inflammatory cytokine and plays an important role in the immune response. Tissue damage or pathogen invasion is always associated with inflammation, which is necessary to help remove necrotic debris. Macrophages are recruited to the infected area in the inflammatory response, which produces reactive oxygen species (ROS) and proteases [Ma J, Chen T, Mandelin J. Regulation of macrophage activation. Cell Mol Life Sci 2003, 60, 2334-2346]. This response helps to kill or degrade the pathogens. Under such a harsh microenvironment, normal cells would also be killed in the absence of a mediator to protect these cells. IL-6, together with various other inflammatory mediators, not only plays an important role in driving inflammatory mechanisms, but also acts as the protector for both cells in the immune system and the injured or infected tissues [Shinozaki M, Hirahashi J, Lebedeva T, et al. IL-15, a survival factor for kidney epithelial cells, counteracts apoptosis and inflammation during nephritis. J Clin Invest 2002, 109, 951-960; Tourbah A, Linnington C, Bachelin C, et al. Inflammation promotes survival and migration of the CG4 oligodendrocyte progenitors transplanted in the spinal cord of both inflammatory and demyelinated EAE rats. J Neurosci Res 1997, 50, 853-861]. However, this protection can go too far and, in some cases, it also extends to cells that strayed from normal cell cycle regulatory pathways [Hideshima T, Nakamura N, Chauhan D, et al. Biologic sequelae of interleukin-6 induced P13-K/Akt signaling in multiple myeloma. Oncogene 2001, 20, 5991-6000], which may eventually cause cancer. Strong support for the role of IL-6 in inflammation and cancer comes from research showing that IL-6 was produced by stroma and inflammatory cells within the tumor microenviroment. The abundant IL-6 then plays its role in activating JAK/STAT3 signal transduction and promotes cell proliferation. In inflammatory cells and tumor cells, extremely high levels of activated STAT3 were observed particularly at the invasive edge of tumors [Bromberg J, Wang T. Inflammation and Cancer: IL-6 and STAT3 Complete the Link. Cancer Cell 2009, 15, 79-80]. Another piece of evidence showing the role of IL-6 in protecting cancer cells comes from the fact that IL-6 is found to mediate many unwanted effects, such as making cancer cells resistant to chemotherapeutic drugs [Hodge D R, Xiao W, Wang L H, et al. Activating mutations in STAT3 and STAT5 differentially affect cellular proliferation and apoptotic resistance in multiple myeloma cells. Cancer Biol Ther 2004, 3, 188-194; Frassanito M A, Cusmai A, Iodice G, et al. Autocrine interleukin-6 production and highly malignant multiple myeloma: relation with resistance to drug-induced apoptosis. Blood 2001, 97, 483-489].
So far, researchers have found that there are numerous cell types which can respond to IL-6; the cell types include but are not limited to, lung, heart, ovary, kidney, liver, macrophages, astrocytes, endometrial stromal cells, monocytes, amnion-derived cells, Kupffer cells, osteoblasts, microglia, multiple myeloma, Leydig cell precursors (testes), mast cells, fibroblasts (dental pulp, gingival, nasal turbinate, polyps, synovial), human endothelial cells, and prostatic intraepithelial neoplasia cells [Suganuma M, Okabe S, Kurusu M, et al. Discrete roles of cytokines, TNF-alpha, IL-1, IL-6 in tumour promotion and cell transformation. Int J Oncol 2002, 20, 131-136]. Low level production of IL-6 typically occurs in these cells. However in a situation like inflammation, IL-6 is constantly expressed at a high level, which drives inflammation itself but also increases the risk of tumorigenesis in these types of cells, mainly through the IL-6/JAK/STAT3 signal transduction pathway. Indeed, various types of cancers are found to be associated with the IL-6/JAK/STAT3 signal transduction pathway, which includes multiple myeloma, chronic lymphocytic leukemia (CLL), acute myelogenous leukemia (AML), large granular lymphocyte leukemia (LGL), lung cancer, breast cancer, renal cancer, prostate cancer, pancreatic carcinoma, melanoma, colon carcinoma, gastric carcinoma, cervical cancer, ovarian cancer, liver cancer, and head and neck cancers [David R H, Elaine M H, William L F. The role of IL-6 and STAT3 in inflammation and cancer. Eur J Cancer 2005, 2502-2512].
As discussed above, IL-6 belongs to the gp130-related cytokine family. It plays an important role in the IL-6/gp130/STAT3 signaling pathway, which was found to be protumorigenic in many cancers. IL-6 first binds to the IL-6 receptor a (IL-6Ra), which recruits gp130 on the cell membrane; then dimerization of two of the IL-6/IL-6Ra/gp130 trimers allows signal transduction via gp130 cytoplasmic domains. This activates JAK then STAT3 (Tyr705 phosphorylation), leading to STAT3 nuclear translocation, DNA binding, and the transcription of multiple oncogenes. To date, very few small molecules have been identified as IL-6/gp130 inhibitors. MDL-A is a natural product that was found to specifically interfere with the IL-6/gp130 interaction surface. However, it's no longer produced in nature (due to mutation in the bacterial strain) and synthetic complexity together with its relatively low binding affinity limits its potential as a lead compound. Although some MDL-A analogues were designed and made, their tedious synthesis and relatively weak potency make them less promising. Raloxifene and bazedoxifene were found to be IL-6/gp130 inhibitors, but they are already FDA approved drugs known as selective estrogen receptor modulators (SERMs) used for the treatment of postmenopausal osteoporosis, which may cause side effects when used to treat cancer. SC144 is another potent small molecule found to bind to gp130, but it inhibits both IL-6 and LIF induced STAT3 nuclear translocation, indicating it may not be a specific IL-6/gp130 inhibitor. Therefore, looking for novel small molecule IL-6/gp130 inhibitors with high potency and specificity as anti-cancer agents is highly desirable.

A “leaving group” (LG) is an art-understood term referring to an atomic or molecular fragment that departs with a pair of electrons in heterolytic bond cleavage, wherein the molecular fragment is an anion or neutral molecule. As used herein, a leaving group can be an atom or a group capable of being displaced by a nucleophile. See e.g., Smith, March Advanced Organic Chemistry 6th ed. (501-502). Exemplary leaving groups include, but are not limited to, halo (e.g., fluoro, chloro, bromo, iodo) and activated substituted hydroxyl groups (e.g., —OC(═O)SRaa, —OC(═O)Raa, —OCO2Raa, —OC(═O)N(Rbb)2, —OC(═NRbb)Raa, —OC(═NRbb)ORaa, —OC(═NRbb)N(Rbb)2, —OS(═O)Raa, —OSO2Raa, −OP(Rcc)2, −OP(Raa)3, —OP(═O)2Raa, —OP(═O)(Raa)2, —OP(═O)(ORcc)2, —OP(═O)2N(Rbb)2, and —OP(═O)(NRbb)2, wherein Raa, Rbb, and Rcc are as defined herein).

In some embodiments, the leaving group is a brosylate, such as p-bromobenzenesulfonyloxy. In some embodiments, the leaving group is a nosylate, such as 2-nitrobenzenesulfonyloxy. In some embodiments, the leaving group is a sulfonate-containing group. In some embodiments, the leaving group is a tosylate group. In some embodiments, the leaving group is a phosphineoxide (e.g., formed during a Mitsunobu reaction) or an internal leaving group such as an epoxide or cyclic sulfate. Other non-limiting examples of leaving groups are water, ammonia, alcohols, ether moieties, thioether moieties, zinc halides, magnesium moieties, diazonium salts, and copper moieties.
Use of the phrase “at least one instance” refers to 1, 2, 3, 4, or more instances, but also encompasses a range, e.g., for example, from 1 to 4, from 1 to 3, from 1 to 2, from 2 to 4, from 2 to 3, or from 3 to 4 instances, inclusive.
A “non-hydrogen group” refers to any group that is defined for a particular variable that is not hydrogen.

In some embodiments, the carbohydrate is a monosaccharide or a disaccharide. In some embodiments, the carbohydrate is made up of one or more monosaccharide units having at least 4, 5 or 6 carbon atoms (which may be linear, branched or cyclic) with an oxygen, nitrogen or sulfur atom bonded to each carbon atom; or a compound having as a part thereof a carbohydrate moiety made up of one or more monosaccharide units. Without limitations, the term “carbohydrate” is intended to include monomeric sugar alcohols, polysaccharides, oligosaccharides and other carbohydrate polymers.

As used herein, the term “salt” refers to any and all salts, and encompasses pharmaceutically acceptable salts. Salts include ionic compounds that result from the neutralization reaction of an acid and a base. A salt is composed of one or more cations (positively charged ions) and one or more anions (negative ions) so that the salt is electrically neutral (without a net charge). Salts of the compounds of this disclosure include those derived from inorganic and organic acids and bases. Examples of acid addition salts are salts of an amino group formed with inorganic acids, such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, and perchloric acid, or with organic acids, such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, or malonic acid or by using other methods known in the art such as ion exchange. Other salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate, hippurate, and the like.

Further salts include ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate, and aryl sulfonate.
The term “pharmaceutically acceptable salt” refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response, and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, Berge et al. describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1-19, incorporated herein by reference. Pharmaceutically acceptable salts of the compounds of this disclosure include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids, such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, and perchloric acid or with organic acids, such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, or malonic acid or by using other methods known in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate salts, and the like. Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium, and N+(C1-4 alkyl)4− salts.

Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate, and aryl sulfonate.
The term “solvate” refers to forms of the compound, or a salt thereof, that are associated with a solvent, usually by a solvolysis reaction. This physical association may include hydrogen bonding. Conventional solvents include water, methanol, ethanol, acetic acid, DMSO, THF, diethyl ether, and the like. The compounds described herein may be prepared, e.g., in crystalline form, and may be solvated. Suitable solvates include pharmaceutically acceptable solvates and further include both stoichiometric solvates and non-stoichiometric solvates. In certain instances, the solvate will be capable of isolation, for example, when one or more solvent molecules are incorporated in the crystal lattice of a crystalline solid. “Solvate” encompasses both solution-phase and isolatable solvates. Representative solvates include hydrates, ethanolates, and methanolates.
The term “hydrate” refers to a compound that is associated with water. Typically, the number of the water molecules contained in a hydrate of a compound is in a definite ratio to the number of the compound molecules in the hydrate. Therefore, a hydrate of a compound may be represented, for example, by the general formula R·x H2O, wherein R is the compound, and x is a number greater than 0. A given compound may form more than one type of hydrate, including, e.g., monohydrates (x is 1), lower hydrates (x is a number greater than 0 and smaller than 1, e.g., hemihydrates (R·0.5 H2O)), and polyhydrates (x is a number greater than 1, e.g., dihydrates (R·2 H2O) and hexahydrates (R·6 H2O)).
The term “tautomers” or “tautomeric” refers to two or more interconvertible compounds resulting from at least one formal migration of a hydrogen atom and at least one change in valency (e.g., a single bond to a double bond, a triple bond to a single bond, or vice versa). The exact ratio of the tautomers depends on several factors, including temperature, solvent, and pH. Tautomerizations (i.e., the reaction providing a tautomeric pair) may catalyzed by acid or base. Exemplary tautomerizations include keto-to-enol, amide-to-imide, lactam-to-lactim, enamine-to-imine, and enamine-to-(a different enamine) tautomerizations.
It is also to be understood that compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed “isomers”. Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers”.
Stereoisomers that are not mirror images of one another are termed “diastereomers” and those that are non-superimposable mirror images of each other are termed “enantiomers”. When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (−)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a “racemic mixture”. Preferred enantiomerically enriched compounds have an enantiomeric excess of 50% or more, more preferably the compound has an enantiomeric excess of 60%, 70%, 80%, 90%, 95%, 98%, or 99% or more. In preferred embodiments, only one enantiomer or diastereomer of a chiral compound is administered to cells or a subject.
The term “co-crystal” refers to a crystalline structure comprising at least two different components (e.g., a compound disclosed herein and an acid), wherein each of the components is independently an atom, ion, or molecule. In certain embodiments, none of the components is a solvent. In certain embodiments, at least one of the components is a solvent. A co-crystal of a compound disclosed herein and an acid is different from a salt formed from a compound disclosed herein and the acid. In the salt, a compound disclosed herein is complexed with the acid in a way that proton transfer (e.g., a complete proton transfer) from the acid to a compound disclosed herein easily occurs at room temperature. In the co-crystal, however, a compound disclosed herein is complexed with the acid in a way that proton transfer from the acid to a compound disclosed herein does not easily occur at room temperature. In certain embodiments, in the co-crystal, there is no proton transfer from the acid to a compound disclosed herein. In certain embodiments, in the co-crystal, there is partial proton transfer from the acid to a compound disclosed herein. Co-crystals may be useful to improve the properties (e.g., solubility, stability, and ease of formulation) of a compound disclosed herein.
The term “polymorph” refers to a crystalline form of a compound (or a salt, hydrate, or solvate thereof). All polymorphs have the same elemental composition. Different crystalline forms usually have different X-ray diffraction patterns, infrared spectra, melting points, density, hardness, crystal shape, optical and electrical properties, stability, and solubility. Recrystallization solvent, rate of crystallization, storage temperature, and other factors may cause one crystal form to dominate. Various polymorphs of a compound can be prepared by crystallization under different conditions.
The term “prodrug” includes compounds with moieties which can be metabolized in vivo. Generally, the prodrugs are metabolized in vivo by esterases or by other mechanisms to active drugs. Examples of prodrugs and their uses are well known in the art (See, e.g., Berge et al. (1977) “Pharmaceutical Salts”, J. Pharm. Sci. 66:1-19). The prodrugs can be prepared in situ during the final isolation and purification of the compounds, or by separately reacting the purified compound in its free acid form or hydroxyl with a suitable esterifying agent. Hydroxyl groups can be converted into esters via treatment with a carboxylic acid. Examples of prodrug moieties include substituted and unsubstituted, branch or unbranched lower alkyl ester moieties, (e.g., propionoic acid esters), lower alkenyl esters, di-lower alkyl-amino lower-alkyl esters (e.g., dimethylaminoethyl ester), acylamino lower alkyl esters (e.g., acetyloxymethyl ester), acyloxy lower alkyl esters (e.g., pivaloyloxymethyl ester), aryl esters (phenyl ester), aryl-lower alkyl esters (e.g., benzyl ester), substituted (e.g., with methyl, halo, or methoxy substituents) aryl and aryl-lower alkyl esters, amides, lower-alkyl amides, di-lower alkyl amides, and hydroxy amides. Preferred prodrug moieties are propionoic acid esters and acyl esters. Prodrugs which are converted to active forms through other mechanisms in vivo are also included. In aspects, the compounds of the disclosure are prodrugs of any of the formulae herein.
The terms “composition” and “formulation” are used interchangeably.
As used herein, “inhibiting” encompasses preventing, reducing, and halting progression. For example, in the context of IL-6, the term refers to a reduction in the activity of the cytokine. In some embodiments, the term refers to a reduction of the level of activity, e.g., IL-6 activity, to a level that is statistically significantly lower than an initial level, which may, for example, be a baseline level of activity. In some embodiments, the term refers to a reduction of the level of activity, e.g., IL-6 activity, to a level that is less than 75%, less than 50%, less than 40%, less than 30%, less than 25%, less than 20%, less than 10%, less than 9%, less than 8%, less than 7%, less than 6%, less than 5%, less than 4%, less than 3%, less than 2%, less than 1%, less than 0.5%, less than 0.1%, less than 0.01%, less than 0.001%, or less than 0.0001% of an initial level, which may, for example, be a baseline level of activity.
As used herein, “activating” encompasses permitting, increasing, and enhancing progression.
The term “modulate” refers to increases or decreases in the activity of a cell in response to exposure to a compound of the disclosure.
The terms “isolated,” “purified,” or “biologically pure” refer to material that is substantially or essentially free from components that normally accompany it as found in its native state. Purity and homogeneity are typically determined using analytical chemistry techniques such as polyacrylamide gel electrophoresis or high-performance liquid chromatography. Particularly, in embodiments the compound is at least 85% pure, more preferably at least 90% pure, more preferably at least 95% pure, and most preferably at least 99% pure.
The terms “polypeptide,” “peptide” and “protein” are used interchangeably herein to refer to a polymer of amino acid residues. The terms apply to amino acid polymers in which one or more amino acid residue is an artificial chemical mimetic of a corresponding naturally occurring amino acid, as well as to naturally occurring amino acid polymers and non-naturally occurring amino acid polymer.
A “peptide” is a sequence of at least two amino acids. Peptides can consist of short as well as long amino acid sequences, including proteins.
The term “amino acid” refers to naturally occurring and synthetic amino acids, as well as amino acid analogs and amino acid mimetics that function in a manner similar to the naturally occurring amino acids. Naturally occurring amino acids are those encoded by the genetic code, as well as those amino acids that are later modified, e.g., hydroxyproline, D-carboxyglutamate, and O-phosphoserine. Amino acid analogs refers to compounds that have the same basic chemical structure as a naturally occurring amino acid, i.e., an a carbon that is bound to a hydrogen, a carboxyl group, an amino group, and an R group, e.g., homoserine, norleucine, methionine sulfoxide, methionine methyl sulfonium. Such analogs have modified R groups (e.g., norleucine) or modified peptide backbones, but retain the same basic chemical structure as a naturally occurring amino acid. Amino acid mimetics refers to chemical compounds that have a structure that is different from the general chemical structure of an amino acid, but that functions in a manner similar to a naturally occurring amino acid.
The term “protein” refers to series of amino acid residues connected one to the other by peptide bonds between the alpha-amino and carboxy groups of adjacent residues.
Amino acids may be referred to herein by either their commonly known three letter symbols or by the one-letter symbols recommended by the IUPAC-IUB Biochemical Nomenclature Commission.
As to amino acid sequences, one of skill will recognize that individual substitutions, deletions or additions to a peptide, polypeptide, or protein sequence which alters, adds or deletes a single amino acid or a small percentage of amino acids in the encoded sequence is a “conservatively modified variant” where the alteration results in the substitution of an amino acid with a chemically similar amino acid. Conservative substitution tables providing functionally similar amino acids are well known in the art.
Macromolecular structures such as polypeptide structures can be described in terms of various levels of organization. For a general discussion of this organization, see, e.g., Alberts et al., Molecular Biology of the Cell (3rd ed., 1994) and Cantor and Schimmel, Biophysical Chemistry Part I. The Conformation of Biological Macromolecules (1980). “Primary structure” refers to the amino acid sequence of a particular peptide. “Secondary structure” refers to locally ordered, three dimensional structures within a polypeptide. These structures are commonly known as domains. Domains are portions of a polypeptide that form a compact unit of the polypeptide and are typically 50 to 350 amino acids long. Typical domains are made up of sections of lesser organization such as stretches of D-sheet and D-helices. “Tertiary structure” refers to the complete three-dimensional structure of a polypeptide monomer. “Quaternary structure” refers to the three-dimensional structure formed by the noncovalent association of independent tertiary units. Anisotropic terms are also known as energy terms.
A “subject” to which administration is contemplated refers to a human (i.e., male or female of any age group, e.g., pediatric subject (e.g., infant, child, or adolescent) or adult subject (e.g., young adult, middle-aged adult, or senior adult)) or non-human animal. In certain embodiments, the non-human animal is a mammal (e.g., primate (e.g., cynomolgus monkey or rhesus monkey), commercially relevant mammal (e.g., cattle, pig, horse, sheep, goat, cat, or dog), or bird (e.g., commercially relevant bird, such as chicken, duck, goose, or turkey)). In certain embodiments, the non-human animal is a fish, reptile, or amphibian. The non-human animal may be a male or female at any stage of development. The non-human animal may be a transgenic animal or genetically engineered animal. The term “patient” refers to a human subject in need of treatment of a disease.
The term “biological sample” refers to any sample including tissue samples (such as tissue sections and needle biopsies of a tissue); cell samples (e.g., cytological smears (such as Pap or blood smears) or samples of cells obtained by microdissection); samples of whole organisms (such as samples of yeasts or bacteria); or cell fractions, fragments or organelles (such as obtained by lysing cells and separating the components thereof by centrifugation or otherwise). Other examples of biological samples include blood, serum, urine, semen, fecal matter, cerebrospinal fluid, interstitial fluid, mucous, tears, sweat, pus, biopsied tissue (e.g., obtained by a surgical biopsy or needle biopsy), nipple aspirates, milk, vaginal fluid, saliva, swabs (such as buccal swabs), or any material containing biomolecules that is derived from a first biological sample.
The term “target tissue” refers to any biological tissue of a subject (including a group of cells, a body part, or an organ) or a part thereof, including blood and/or lymph vessels, which is the object to which a compound, particle, and/or composition of the disclosure is delivered. A target tissue may be an abnormal or unhealthy tissue, which may need to be treated. A target tissue may also be a normal or healthy tissue that is under a higher than normal risk of becoming abnormal or unhealthy, which may need to be prevented. In certain embodiments, the target tissue is the liver. In certain embodiments, the target tissue is the lung.

It will be appreciated that dose ranges as described herein provide guidance for the administration of provided pharmaceutical compositions to an adult. The amount to be administered to, for example, a child or an adolescent can be determined by a medical practitioner or person skilled in the art and can be lower or the same as that administered to an adult.
A “proliferative disease” refers to a disease that occurs due to abnormal growth or extension by the multiplication of cells (Walker, Cambridge Dictionary of Biology; Cambridge University Press: Cambridge, UK, 1990). A proliferative disease may be associated with: 1) the pathological proliferation of normally quiescent cells; 2) the pathological migration of cells from their normal location (e.g., metastasis of neoplastic cells); 3) the pathological expression of proteolytic enzymes such as the matrix metalloproteinases (e.g., collagenases, gelatinases, and elastases); or 4) the pathological angiogenesis as in proliferative retinopathy and tumor metastasis. Exemplary proliferative diseases include cancers (i.e., “malignant neoplasms”), benign neoplasms, angiogenesis, inflammatory diseases, and autoimmune diseases.
The term “angiogenesis” refers to the physiological process through which new blood vessels form from pre-existing vessels. Angiogenesis is distinct from vasculogenesis, which is the de novo formation of endothelial cells from mesoderm cell precursors. The first vessels in a developing embryo form through vasculogenesis, after which angiogenesis is responsible for most blood vessel growth during normal or abnormal development. Angiogenesis is a vital process in growth and development, as well as in wound healing and in the formation of granulation tissue. However, angiogenesis is also a fundamental step in the transition of tumors from a benign state to a malignant one, leading to the use of angiogenesis inhibitors in the treatment of cancer. Angiogenesis may be chemically stimulated by angiogenic proteins, such as growth factors (e.g., VEGF). “Pathological angiogenesis” refers to abnormal (e.g., excessive or insufficient) angiogenesis that amounts to and/or is associated with a disease.
The terms “neoplasm” and “tumor” are used herein interchangeably and refer to an abnormal mass of tissue wherein the growth of the mass surpasses and is not coordinated with the growth of a normal tissue. A neoplasm or tumor may be “benign” or “malignant,” depending on the following characteristics: degree of cellular differentiation (including morphology and functionality), rate of growth, local invasion, and metastasis. A “benign neoplasm” is generally well differentiated, has characteristically slower growth than a malignant neoplasm, and remains localized to the site of origin. In addition, a benign neoplasm does not have the capacity to infiltrate, invade, or metastasize to distant sites. Exemplary benign neoplasms include, but are not limited to, lipoma, chondroma, adenomas, acrochordon, senile angiomas, seborrheic keratoses, lentigos, and sebaceous hyperplasias. In some cases, certain “benign” tumors may later give rise to malignant neoplasms, which may result from additional genetic changes in a subpopulation of the tumor's neoplastic cells, and these tumors are referred to as “pre-malignant neoplasms.” An exemplary pre-malignant neoplasm is a teratoma. In contrast, a “malignant neoplasm” is generally poorly differentiated (anaplasia) and has characteristically rapid growth accompanied by progressive infiltration, invasion, and destruction of the surrounding tissue. Furthermore, a malignant neoplasm generally has the capacity to metastasize to distant sites. The term “metastasis,” “metastatic,” or “metastasize” refers to the spread or migration of cancerous cells from a primary or original tumor to another organ or tissue and is typically identifiable by the presence of a “secondary tumor” or “secondary cell mass” of the tissue type of the primary or original tumor and not of that of the organ or tissue in which the secondary (metastatic) tumor is located. For example, a prostate cancer that has migrated to bone is said to be metastasized prostate cancer and includes cancerous prostate cancer cells growing in bone tissue.
The term “cancer” refers to a class of diseases characterized by the development of abnormal cells that proliferate uncontrollably and have the ability to infiltrate and destroy normal body tissues. See e.g., Stedman's Medical Dictionary, 25th ed.; Hensyl ed.; Williams & Wilkins: Philadelphia, 1990. Exemplary cancers include, but are not limited to, breast cancer (e.g., adenocarcinoma of the breast, papillary carcinoma of the breast, mammary cancer, medullary carcinoma of the breast); brain cancer (e.g., meningioma, glioblastomas, glioma (e.g., astrocytoma, oligodendroglioma), medulloblastoma); head and neck cancer (e.g., head and neck squamous cell carcinoma, oral cancer (e.g., oral squamous cell carcinoma), throat cancer (e.g., laryngeal cancer, pharyngeal cancer, nasopharyngeal cancer, oropharyngeal cancer)); liver cancer (e.g., hepatocellular cancer (HCC), malignant hepatoma); and prostate cancer (e.g., prostate adenocarcinoma).
The terms “inflammatory disease” and “inflammatory condition” are used interchangeably herein, and refer to a disease or condition caused by, resulting from, or resulting in inflammation. Inflammatory diseases and conditions include those diseases, disorders or conditions that are characterized by signs of pain (dolor, from the generation of noxious substances and the stimulation of nerves), heat (calor, from vasodilatation), redness (rubor, from vasodilatation and increased blood flow), swelling (tumor, from excessive inflow or restricted outflow of fluid), and/or loss of function (functio laesa, which can be partial or complete, temporary or permanent. Inflammation takes on many forms and includes, but is not limited to, acute, adhesive, atrophic, catarrhal, chronic, cirrhotic, diffuse, disseminated, exudative, fibrinous, fibrosing, focal, granulomatous, hyperplastic, hypertrophic, interstitial, metastatic, necrotic, obliterative, parenchymatous, plastic, productive, proliferous, pseudomembranous, purulent, sclerosing, seroplastic, serous, simple, specific, subacute, suppurative, toxic, traumatic, and/or ulcerative inflammation. The term “inflammatory disease” may also refer to a dysregulated inflammatory reaction that causes an exaggerated response by macrophages, granulocytes, and/or T-lymphocytes leading to abnormal tissue damage and/or cell death. An inflammatory disease can be either an acute or chronic inflammatory condition and can result from infections or non-infectious causes.

An “autoimmune disease” refers to a disease arising from an inappropriate immune response of the body of a subject against substances and tissues normally present in the body. In other words, the immune system mistakes some part of the body as a pathogen and attacks its own cells. This may be restricted to certain organs (e.g., in autoimmune thyroiditis) or involve a particular tissue in different places (e.g., Goodpasture's disease which may affect the basement membrane in both the lung and kidney). The treatment of autoimmune diseases is typically with immunosuppression, e.g., medications which decrease the immune response. Exemplary autoimmune diseases include, but are not limited to, glomerulonephritis, Goodpasture's syndrome, necrotizing vasculitis, lymphadenitis, peri-arteritis nodosa, systemic lupus erythematosis, rheumatoid arthritis, psoriatic arthritis, systemic lupus erythematosis, psoriasis, ulcerative colitis, systemic sclerosis, dermatomyositis/polymyositis, anti-phospholipid antibody syndrome, scleroderma, pemphigus vulgaris, ANCA-associated vasculitis (e.g., Wegener's granulomatosis, microscopic polyangiitis), uveitis, Sjogren's syndrome, Crohn's disease, Reiter's syndrome, ankylosing spondylitis, Lyme disease, Guillain-Barré syndrome, Hashimoto's thyroiditis, and cardiomyopathy.

The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.
In order to prolong the effect of a drug, it is often desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This can be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution, which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form may be accomplished by dissolving or suspending the drug in an oil vehicle.
Compositions for rectal or vaginal administration are typically suppositories which can be prepared by mixing the conjugates described herein with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol, or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active ingredient.

Cells were harvested and lysed in cold radioimmunoprecipitation assay (RIPA) lysis buffer containing proteasome inhibitor cocktail and phosphatase inhibitor cocktail. The protein concentrations were determined using the BCA Protein Assay kit. After adding the loading buffer and boiling at 95° C. for 10 minutes, equivalent amounts of proteins were loaded on and separated by SDS-PAGE, and then were transferred to PVDF membranes. Membranes were probed with primary antibodies (1:1000) against gp130 and GAPDH. Membranes were analyzed using Enhanced Chemiluminescence Plus reagents and either scanned with the Storm Scanner (Amersham Pharmacia Biotech, Inc., Piscataway, NJ) or imaged with ChemiDoc MP imaging system (Bio-Rad, Hercules, CA).
MDA-MB-231 breast cancer cells or MIAPaCa2 pancreatic cancer cells were lysed in cold radioimmunoprecipitation assay (RIPA) lysis buffer containing proteasome inhibitor cocktail and phosphatase inhibitor cocktail. Then lysates were incubated with escalating concentrations (10-1000 μM) of LS-28-3 or bazedoxifene at room temperature for 1 h. Proteolysis was followed by adding protease pronase solution at a ratio of 1 mg of pronase to 1000 mg (or 2000 mg) of lysate protein for 20 min at room temperature. To stop proteolysis, 4 x SDS sample loading buffer was added at 1:3 ratio to each sample and boiled at 95° C. for 10 min. The resulted protein samples were separated by 8% SDS-PAGE gel and analyzed by western blotting.
The DARTS assay is a method for studying the specific protein-ligand binding interactions. It is based on the principle that the target protein structure might be stabilized and become less susceptible to proteolysis by proteases upon drug binding [Lomenick B, Jung G, Wohlschlegel J, et al. Target identification using drug affinity responsive target stability (DARTS). Curr Protoc Chem Biol 2011, 3, 163-180; Lomenick B, Olsen R, Huang J. Identification of direct protein targets of small molecules. ACS Chem Biol. 2011, 6, 34-46]. It can be used to find the targeting protein of a small molecule by running SDS-gel without purifying any specific protein. It can also be used to verify whether a small molecule is targeting a designated protein by western blotting. Recently, this method was successfully used to assess the direct binding of potential inhibitor SC144 to gp130 in human ovarian cells and raloxifene to gp130 in human RH30 sarcoma cells [Li H, Xiao H, Lin L, et al. Drug design targeting protein-protein interactions (PPIs) using multiple ligand simultaneous docking (MLSD) and drug repositioning: discovery of raloxifene and bazedoxifene as novel inhibitors of IL-6/GP130 interface. J Med Chem 2014, 57, 632-641; Xu S, Grande1 F, Garofalo A, et al. Discovery of a novel orally active small-molecule gp130 inhibitor for the treatment of ovarian cancer. Mol Cancer Ther 2013, 12, 937-949].
To investigate the binding of LS-28-3 to gp130, DARTS assays were performed using MDA-MB-231 breast cancer cell lysates or MIAPaCa2 pancreatic cancer cell lysates, following the protocol as previously described. In both MDA-MB-231 breast cancer cell lysates (
Cell viability of MDA-MB-231 breast cancer cells was evaluated by using the MTT assay in triple replicates in one experiment and repeated for three times (
Cell viability of AML-12 hepatocyte cells was evaluated by using the MTT assay in triple replicates in one experiment and repeated for three times (
Inhibition of downstream STAT3 phosphorylation was performed. T47D breast cancer cells, which lack endogenous IL-6, were treated with LLM418-MCBu for 2 hours. Then, cytokine was administered for 30 minutes (IL-6, INF, LIF, or OSM). Western blot conducted afterwards to assess dose-dependent inhibition of IL-6 signaling (or lack thereof) (
IL-6 is a pleiotropic cytokine produced by a wide variety of cells in the body and is involved in the regulation of many different cellular processes1,2. Due to this, it has a significant role in the progression of several disease states, including autoimmune diseases, inflammatory diseases, and cancer1,2. Its involvement in these disease states makes it an attractive target.
However, the only currently available drugs are engineered proteins or monoclonal antibodies3, indicating a potential demand for a small molecule alternative. Towards this effort, the natural product Madindoline A (MDL-A) was discovered to be a selective IL-6 inhibitor in 19995. However, later studies indicated that despite its great selectivity, MDL-A had poor activity and a low-yield total synthesis, making analogue development relatively undesirable3,6.
MDL-A was determined to bind to the extracellular domain of glycoprotein 130 (gp130) with a KD of 288 μM6. Of the different cytokines that bind to gp130, only IL-6 and IL-11 require two gp130 units and the formation of a hexameric structure for signaling, which is the driving force behind the selectivity of MDL-A3,9. In order to conduct a structure-based drug design approach to developing small molecules with identical selectivity and superior activity, the precise binding mode of MDL-A to gp130 had to be determined. Through the use of docking and molecular dynamics simulations, the binding mode of MDL-A was identified9. Three “hot spots” were identified as playing a significant role in the binding of MDL-A to gp1309. These include a hydrophobic pocket, which is seen interacting with the aliphatic chain of MDL-A, tyrosine 94, which engages in pi-pi interactions, and asparagine 92, which engages in hydrogen bonding9. By maximizing interactions between these hot spots, more effective IL-6 inhibitors can be developed.
Based on the identification of MDL-A as a selective IL-6/gp130 protein-protein interaction inhibitor, a thorough structure-based drug design study has been conducted. With the culmination of several generations of IL-6 signaling inhibitors as well as drug repositioning efforts, a current generation of selective inhibitors has been developed, with lead compounds possessing single-digit micromolar activity. Additionally, the groundwork has been laid for the design and synthetic approach towards future generations, both with a basis on LLM4/LLM418 as well as on indole alkaloid natural products.
