Definitions

  • This invention relates to compounds. More specifically, the invention relates to compounds useful as kinase inhibitors, along with processes to prepare the compounds and uses of the compounds. Specifically, the invention relates to inhibitors of Bruton's tyrosine kinase (BTK).
  • BTK Bruton's tyrosine kinase
  • Kinases are a class of enzyme that control the transfer of phosphate groups from phosphate donor groups, for example ATP, to specific substrates.
  • Protein kinases are a subset of kinases and BTK is one such protein kinase.
  • BTK is a member of the src-related Tec family of cytoplasmic tyrosine kinases. BTK plays a key role in the signalling pathways of B-cells, affecting B-cell development, activation, signalling and survival. In certain malignancies, B-cells overexpress BTK. These malignant B-cells and the overexpression of BTK by the cells has been associated with the increased proliferation and survival of tumor cells. Inhibition of BTK affects the B-cell signalling pathways, preventing activation of B-cells and inhibiting the growth of malignant B-cells.
  • BTK inhibitors that have been reported are Ibrutinib (PCI-32765) and CC-292.
  • CC-292 is manufactured by Avila Pharmaceuticals who have filed applications for protein kinases published as WO 201 1 /090760 and WO 2009/158571 .
  • Ibrutinib is disclosed in at least US 2008/0076921 .
  • Ibrutinib has found that it possesses a number of undesirable pharmacological features. For example, Ibrutinib is poorly soluble and is a weak inhibitor of hERG. Furthermore, rat pharmacokinetic data has shown that Ibrutinib has a low estimated fraction absorbed, poor bioavailability and a high clearance rate from the body, with a terminal T1 2 of 1 .5 hours.
  • WO 2013/010136 disclosed BTK inhibitors with a related structure to Ibrutinib.
  • BTK inhibitors e.g. Ibrutinib
  • Ibrutinib have presented gastrointestinal side effects. These side effects have been attributed to the EGFR inhibitory activity of the BTK inhibitors. It is therefore desirable to have a BTK inhibitor with high BTK inhibition and low EGFR inhibition to reduce or avoid the gastrointestinal side effects. Such high BTK inhibition and low EGFR inhibition is readily identified by a large "Fold Selectivity" value.
  • an aim of the present invention is to provide BTK inhibitors.
  • the invention aims to provide BTK inhibitors with high selectivity for BTK inhibition over EGFR inhibition.
  • the invention provides compounds capable of inhibiting Bruton's tyrosine kinase (BTK) and the use of these compounds in inhibiting BTK.
  • BTK Bruton's tyrosine kinase

Description

PYRAZOLO-PYRIMIDINES AS INHIBITORS OF BTK
[0001] This invention relates to compounds. More specifically, the invention relates to compounds useful as kinase inhibitors, along with processes to prepare the compounds and uses of the compounds. Specifically, the invention relates to inhibitors of Bruton's tyrosine kinase (BTK).
BACKGROUND
[0002] Kinases are a class of enzyme that control the transfer of phosphate groups from phosphate donor groups, for example ATP, to specific substrates. Protein kinases are a subset of kinases and BTK is one such protein kinase.
[0003] BTK is a member of the src-related Tec family of cytoplasmic tyrosine kinases. BTK plays a key role in the signalling pathways of B-cells, affecting B-cell development, activation, signalling and survival. In certain malignancies, B-cells overexpress BTK. These malignant B-cells and the overexpression of BTK by the cells has been associated with the increased proliferation and survival of tumor cells. Inhibition of BTK affects the B-cell signalling pathways, preventing activation of B-cells and inhibiting the growth of malignant B-cells.
[0004] A number of clinical trials have shown that BTK inhibitors are affective against cancer.
[0005] BTK inhibitors that have been reported are Ibrutinib (PCI-32765) and CC-292. CC-292 is manufactured by Avila Pharmaceuticals who have filed applications for protein kinases published as WO 201 1 /090760 and WO 2009/158571 . Ibrutinib is disclosed in at least US 2008/0076921 .
Studies on Ibrutinib have found that it possesses a number of undesirable pharmacological features. For example, Ibrutinib is poorly soluble and is a weak inhibitor of hERG. Furthermore, rat pharmacokinetic data has shown that Ibrutinib has a low estimated fraction absorbed, poor bioavailability and a high clearance rate from the body, with a terminal T1 2 of 1 .5 hours.
[0006] Since Ibrutinib was first disclosed there have been a number of patent applications concerned with structures closely related to Ibrutinib, for example see WO 2012/158843, WO 2012/158764, WO 201 1/153514, WO 201 1/046964, US 2010/0254905, US 2010/0144705, US 7718662, WO, 2008/054827 and WO 2008/121742.
[0007] Most recently, WO 2013/010136 disclosed BTK inhibitors with a related structure to Ibrutinib.
[0008] Known BTK inhibitors, e.g. Ibrutinib, have presented gastrointestinal side effects. These side effects have been attributed to the EGFR inhibitory activity of the BTK inhibitors. It is therefore desirable to have a BTK inhibitor with high BTK inhibition and low EGFR inhibition to reduce or avoid the gastrointestinal side effects. Such high BTK inhibition and low EGFR inhibition is readily identified by a large "Fold Selectivity" value.
[0009] Therefore, an aim of the present invention is to provide BTK inhibitors. In addition the invention aims to provide BTK inhibitors with high selectivity for BTK inhibition over EGFR inhibition. SU M MARY OF THE DISCLOSURE

Furthermore, the invention provides compounds capable of inhibiting Bruton's tyrosine kinase (BTK) and the use of these compounds in inhibiting BTK. In accordance with the invention there is provided a method of treating conditions modulated by BTK. The invention provides compounds for use in treating a condition which is modulated by BTK.
[0011] In a first aspect of the invention there is provided a compound according to formula (I):

[0097] The term "alkheteroaryl" refers to a heteroaryl group, as defined above, bonded to a
Ci-4 alkyl, where the alkyl group provides attachment to the remainder of the molecule. [0098] The term "halogen" herein includes reference to F, CI, Br and I. Halogen may be CI.
Halogen may be F.
[0099] A bond terminating in a " " represents that the bond is connected to another atom that is not shown in the structure. A bond terminating inside a cyclic structure and not terminating at an atom of the ring structure represents that the bond may be connected to any of the atoms in the ring structure where allowed by valency.
[00100] Where a moiety is substituted, it may be substituted at any point on the moiety where chemically possible and consistent with atomic valency requirements. The moiety may be substituted by one or more substituents, e.g. 1 , 2, 3 or 4 substituents; optionally there are 1 or 2 substituents on a group. Where there are two or more substituents, the substituents may be the same or different. The substituent(s) may be selected from: OH, NHR9, amidino, guanidino, hydroxyguanidino, formamidino, isothioureido, ureido, mercapto, C(0)H, acyl, acyloxy, carboxy, sulfo, sulfamoyl, carbamoyl, cyano, azo, nitro, halo, Ci-e alkyl, Ci-e alkoxy, Ci-e haloalkyl, C3-8 cycloalkyl, C2-6 alkenyl, C2-6 alkynyl, aryl, heteroaryl or alkaryl. Where the group to be substituted is an alkyl group the substituent may be =0. Where the moiety is substituted with two or more substituents and two of the substituents are adjacent the adjacent substituents may form a C4-8 ring along with the atoms of the moiety on which the substituents are substituted, wherein the C4-8 ring is a saturated or unsaturated hydrocarbon ring with 4, 5, 6, 7, or 8 carbon atoms or a saturated or unsaturated hydrocarbon ring with 4, 5, 6, 7, or 8 carbon atoms and 1 , 2 or 3 heteroatoms. [00101] Substituents are only present at positions where they are chemically possible, the person skilled in the art being able to decide (either experimentally or theoretically) without inappropriate effort which substitutions are chemically possible and which are not.
[00102] Ortho, meta and para substitution are well understood terms in the art. For the absence of doubt, "ortho" substitution is a substitution pattern where adjacent carbons possess a substituent, whether a simple group, for example the fluoro group in the example below, or other portions of the molecule, as indicated by the bond ending in " ".
Figure imgf000037_0001
[00103] "Meta" substitution is a substitution pattern where two substituents are on carbons one carbon removed from each other, i.e with a single carbon atom between the substituted carbons. In other words there is a substituent on the second atom away from the atom with another substituent. For example the groups below are meta substituted.
Figure imgf000037_0002
[00104] "Para" substitution is a substitution pattern where two substituents are on carbons two carbons removed from each other, i.e with two carbon atoms between the substituted carbons. In other words there is a substituent on the third atom away from the atom with another substituent. For example the groups below are para substituted.
Figure imgf000037_0003
[00105] By "acyl" is meant an organic radical derived from, for example, an organic acid by the removal of the hydroxyl group, e.g. a radical having the formula R-C(O)-, where R may be selected from H, Ci-6 alkyl, C3-8 cycloalkyl, phenyl, benzyl or phenethyl group, eg R is H or C1-3 alkyl. In one embodiment acyl is alkyl-carbonyl. Examples of acyl groups include, but are not limited to, formyl, acetyl, propionyl and butyryl. A particular acyl group is acetyl.
[00106] Throughout the description the disclosure of a compound also encompasses
pharmaceutically acceptable salts, solvates and stereoisomers thereof. Where a compound has a stereocentre, both (R) and (S) stereoisomers are contemplated by the invention, equally mixtures of stereoisomers or a racemic mixture are completed by the present application. Where a compound of the invention has two or more stereocentres any combination of (R) and (S) stereoisomers is contemplated. The combination of (R) and (S) stereoisomers may result in a diastereomeric mixture or a single diastereoisomer. The compounds of the invention may be present as a single stereoisomer or may be mixtures of stereoisomers, for example racemic mixtures and other enantiomeric mixtures, and diasteroemeric mixtures. Where the mixture is a mixture of enantiomers the enantiomeric excess may be any of those disclosed above. Where the compound is a single stereoisomer the compounds may still contain other diasteroisomers or enantiomers as impurities. Hence a single stereoisomer does not necessarily have an enantiomeric excess (e.e.) or diastereomeric excess (d.e.) of 100% but could have an e.e. or d.e. of about at least 85%
[00107] The invention contemplates pharmaceutically acceptable salts of the compounds of formula (I). These may include the acid addition and base salts of the compounds. These may be acid addition and base salts of the compounds. In addition the invention contemplates solvates of the compounds. These may be hydrates or other solvated forms of the compound.
[00108] Suitable acid addition salts are formed from acids which form non-toxic salts. Examples include the acetate, aspartate, benzoate, besylate, bicarbonate/carbonate, bisulfate/sulfate, borate, camsylate, citrate, edisylate, esylate, formate, fumarate, gluceptate, gluconate, glucuronate, hexafluorophosphate, hibenzate, hydrochloride/chloride, hydrobromide/bromide, hydroiodide/iodide, isethionate, lactate, malate, maleate, malonate, mesylate, methylsulfate, naphthylate, 1 ,5- naphthalenedisulfonate, 2-napsylate, nicotinate, nitrate, orotate, oxalate, palmitate, pamoate, phosphate/hydrogen phosphate/dihydrogen phosphate, saccharate, stearate, succinate, tartrate, tosylate and trifluoroacetate salts. [00109] Suitable base salts are formed from bases which form non-toxic salts. Examples include the aluminium, arginine, benzathine, calcium, choline, diethylamine, diolamine, glycine, lysine, magnesium, meglumine, olamine, potassium, sodium, tromethamine and zinc salts. Hemisalts of acids and bases may also be formed, for example, hemisulfate and hemicalcium salts. For a review on suitable salts, see "Handbook of Pharmaceutical Salts: Properties, Selection, and Use" by Stahl and Wermuth (Wiley-VCH, Weinheim, Germany, 2002).
[00110] Pharmaceutically acceptable salts of compounds of formula (I) may be prepared by one or more of three methods:
(i) by reacting the compound of formula (I) with the desired acid or base;
(ii) by removing an acid- or base-labile protecting group from a suitable precursor of the compound of formula (I) or by ring-opening a suitable cyclic precursor, for example, a lactone or lactam, using the desired acid or base; or
(iii) by converting one salt of the compound of formula (I) to another by reaction with an appropriate acid or base or by means of a suitable ion exchange column.
[0011 1] All three reactions are typically carried out in solution. The resulting salt may precipitate out and be collected by filtration or may be recovered by evaporation of the solvent. The degree of ionisation in the resulting salt may vary from completely ionised to almost non-ionised. [00112] The compounds of the invention may exist in both unsolvated and solvated forms. The term 'solvate' is used herein to describe a molecular complex comprising the compound of the invention and a stoichiometric amount of one or more pharmaceutically acceptable solvent molecules, for example, ethanol. The term 'hydrate' is employed when said solvent is water. [00113] Included within the scope of the invention are complexes such as clathrates, drug-host inclusion complexes wherein, in contrast to the aforementioned solvates, the drug and host are present in stoichiometric or non-stoichiometric amounts. Also included are complexes of the drug containing two or more organic and/or inorganic components which may be in stoichiometric or non- stoichiometric amounts. The resulting complexes may be ionised, partially ionised, or non- ionised. For a review of such complexes, see J Pharm Sci, 64 (8), 1269-1288 by Haleblian (August 1975).
[00114] Hereinafter all references to compounds of any formula include references to salts, solvates and complexes thereof and to solvates and complexes of salts thereof.
[00115] The compounds of the invention include compounds of a number of formula as herein defined, including all polymorphs and crystal habits thereof, prodrugs and isomers thereof (including optical, geometric and tautomeric isomers) as hereinafter defined and isotopically-labeled compounds of the invention.
[00116] Before purification, the compounds of the present invention may exist as a mixture of enantiomers depending on the synthetic procedure used. The enantiomers can be separated by conventional techniques known in the art. Thus the invention covers individual enantiomers as well as mixtures thereof.
[00117] For some of the steps of the process of preparation of the compounds of formula (I), it may be necessary to protect potential reactive functions that are not wished to react, and to cleave said protecting groups in consequence. In such a case, any compatible protecting radical can be used. In particular methods of protection and deprotection such as those described by T.W.
GREENE (Protective Groups in Organic Synthesis, A. Wiley- Interscience Publication, 1981) or by P. J. Kocienski (Protecting groups, Georg Thieme Verlag, 1994), can be used. All of the above reactions and the preparations of novel starting materials used in the preceding methods are conventional and appropriate reagents and reaction conditions for their performance or preparation as well as procedures for isolating the desired products will be well-known to those skilled in the art with reference to literature precedents and the examples and preparations hereto.
[00118] Also, the compounds of the present invention as well as intermediates for the preparation thereof can be purified according to various well-known methods, such as for example
crystallization or chromatography.

[00797] Example 48: TMD8 Growth Inhibition Assay
[00798] Compounds were assayed for effects on the growth of TMD8 human ABC-DLBCL cells that are dependent on NFKB signalling. TMD8 cells were grown in suspension in T225 flasks, centrifuged and re-suspended in 2.5% FBS containing media. Cells were then plated at 1 .0x104 cells per well in 96-well plates in varying concentrations of compound and incubated for 72 h at 37 °C. An additional plate of cells to be used as the Day 0 read was seeded without compound addition, Resazurin was added to each well, incubated for 5 hours and the fluorescence measured at 590 nm. After 72 h of compound treatment, Resazurin was added to each well of the compound treated plates, incubated for 5 h and the fluorescence measured at 590 nm. The IC50 was then calculated but subtracting the average Day 0 value from each well value from the treated plates, each treatment was then calculated as a percentage of the DMSO control and the percentages plotted against the inhibitor concentration to estimate the ICso from log[lnhibitor] vs response using the Variable Slope model in Graphpad prism from Graphpad software (SanDiego, Calif).
