The present disclosure is directed to small molecule tyrosine kinase inhibitors.
Rheumatoid arthritis (“RA”) is a chronic, autoimmune, inflammatory disorder that affects the lining of the joints, causing painful swelling that can result in bone erosion and joint deformation. RA presents a significant societal impact—it has a relatively high prevalence (about 1% of the United States population suffers from RA), produces irreversible joint damage, and has a widespread occurrence of co-morbities. While many patients benefit from currently marketed biologic and small molecule medicines, most patients still suffered from the chronic pain and inflammation of the disease.
Cancer, in particular mantle cell lymphoma, chronic lymphocytic leukemia, macroglobulinemia, and multiple myeloma, continues to afflict patients. Alternative, effective treatments of cancer are still needed.
Human Bruton's tyrosine kinase (“Btk”) is a ˜76 kDa protein belonging to the Tec family of non-receptor tyrosine kinases. Tec kinases form the second largest family of cytoplasmic tyrosine kinases in mammalian cells, which consists of four other members in addition to BTK: the eponymous kinase TEC, ITK, TXK/RLK and BMX. Tec kinases are evolutionarily conserved throughout vertebrates. They are related to, but structurally distinct from, the larger Src and Syk kinase families. Tec family proteins are abundantly expressed in hematopoietic tissues and play important roles in the growth and differentiation of blood and endothelial cells in mammals.
Based upon Btk expression from IHC studies described in the art, Btk inhibition has the potential to modulate biology associated with B cells, macrophages, mast cells, osteoclasts, and platelet microparticles. Corneth, O. B., et al. Curr. Top. Microbiol. Immunol. BTK Signaling in B Cell Differentiation and Autoimmunity. 2015 Sep. 5. The role of B cells in RA is supported by the therapeutic benefit exhibited in the clinic upon B cell depletion with Rituximab™. Since auto-reactive antibodies play such a critical role in synovial inflammation, therapeutic modulation of the B cell compartment is an attractive mechanism to treat early RA and potentially modulate disease at the earliest stages. B cell depletion in murine models such as collagen-induced arthritis (CIA) prevents arthritis development. Svensson, et al. (1998) B cell-deficient mice do not develop type II collagen-induced arthritis (CIA). Clin Exp Immunol 111, 521-526.

Examples of excipients include calcium carbonate, calcium phosphate, various sugars and types of starch, cellulose derivatives, gelatin, vegetable oils, and polyethylene glycols.
“Subject” includes humans. The terms “human,” “patient,” and “subject” are used interchangeably herein.
“Treating” or “treatment” of any disease or disorder refers, in one embodiment, to ameliorating the disease or disorder (i.e., arresting or reducing the development of the disease or at least one of the clinical symptoms thereof). In another embodiment “treating” or “treatment” refers to ameliorating at least one physical parameter, which may not be discernible by the subject. In yet another embodiment, “treating” or “treatment” refers to modulating the disease or disorder, either physically, (e.g., stabilization of a discernible symptom), physiologically, (e.g., stabilization of a physical parameter), or both. In yet another embodiment, “treating” or “treatment” refers to delaying the onset of the disease or disorder.
“Compounds of the present disclosure,” and equivalent expressions, are meant to embrace compounds of the Formula (I) as described herein, which expression includes the pharmaceutically acceptable salts, and the solvates, e.g., hydrates, where the context so permits. Similarly, reference to intermediates, whether or not they themselves are claimed, is meant to embrace their salts, and solvates, where the context so permits.
As used herein, the term “isotopic variant” refers to a compound that contains unnatural proportions of isotopes at one or more of the atoms that constitute such compound. For example, an “isotopic variant” of a compound can be radiolabeled, that is, contain one or more non-radioactive isotopes, such as for example, deuterium (2H or D), carbon-13 (13C), nitrogen-15 (15N), or the like. It will be understood that, in a compound where such isotopic substitution is made, the following atoms, where present, may vary, so that for example, any hydrogen may be 2H/D, any carbon may be 13C, or any nitrogen may be 15N, and that the presence and placement of such atoms may be determined within the skill of the art. Likewise, the disclosure may include the preparation of isotopic variants with radioisotopes, in the instance for example, where the resulting compounds may be used for drug and/or substrate tissue distribution studies. Radiolabeled compounds of the disclosure can be used in diagnostic methods such as Single-photon emission computed tomography (SPECT). The radioactive isotopes tritium, i.e. 3H, and carbon-14, i.e. 14C, are particularly useful for their ease of incorporation and ready means of detection. Further, compounds may be prepared that are substituted with positron emitting isotopes, such as 11C, 18F, 15O and 13N, and would be useful in Positron Emission Topography (PET) studies for examining substrate receptor occupancy.
All isotopic variants of the compounds of the disclosure, radioactive or not, are intended to be encompassed within the scope of the disclosure.
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,” for example, diastereomers, enantiomers, and atropisomers.
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.”
“Atropisomers” refer to stereoisomers that arise because of hindered rotation around a single bond.
“Tautomers” refer to compounds that are interchangeable forms of a particular compound structure, and that vary in the displacement of hydrogen atoms and electrons. Thus, two structures may be in equilibrium through the movement of π electrons and an atom (usually H). For example, enols and ketones are tautomers because they are rapidly interconverted by treatment with either acid or base. Another example of tautomerism is the aci- and nitro-forms of phenyl nitromethane, that are likewise formed by treatment with acid or base.
Tautomeric forms may be relevant to the attainment of the optimal chemical reactivity and biological activity of a compound of interest.
The compounds of this disclosure may possess one or more asymmetric centers; such compounds can therefore be produced as individual (R)- or (S)-stereoisomers or as mixtures thereof.
Unless indicated otherwise, the description or naming of a particular compound in the specification and claims is intended to include both individual enantiomers and mixtures, racemic or otherwise, thereof. Within the present disclosure, any open valency appearing on a carbon, oxygen, or nitrogen atom in any structure described herein indicates the presence of a hydrogen atom. Where a chiral center exists in a structure, but no specific stereochemistry is shown for that center, both enantiomers, separately or as a mixture, are encompassed by that structure. The methods for the determination of stereochemistry and the separation of stereoisomers are well-known in the art.

BTK Kinase Lanthascreen Binding Assay:
A BTK kinase lanthascreen binding assay monitors compound binding to unphosphorylated-BTK kinase domain (UP-BTK), by competing with a fluorescent labeled tracer. UP-BTK, consisting of the kinase domain of non-phosphorylated BTK protein (389-659aa), was produced in a Baculovirus/insect cell expression system. Into a 384-well plate, 2 ng of GST-tagged human BTK (389-659aa) was incubated with compound, 50 nM of Tracer 236 and 2 nM anti-GST antibody for 60 minutes using an optimized Lanthascreen™ assay. After 60 minutes, plates were read at 340 nM and 615/665 nM in an Infinite F500 (Tecan). Data were analyzed using Xlfit™ version 5.3 from ID Business Solutions (Guildford), Microsoft Excel add-in. pIC50 refers to the negative log of the IC50 in molar.
