Description

Compounds [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 AlP, 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 AVL-292.

AVL-292 is manufactured by Avila Pharmaceuticals who have filed applications for protein kinases published as WO 2011/090760 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 hERO. 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 11,2 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 2012/156843, wa 2012/158764, WO 2011/153514, wa 2011/046964, US 201 0/0254905, US 2010/01 44705, US 7718662, wa, 2008/054827 and WO 2008/121742.

[0007] Most recently, Wa 2013/010136 disclosed BTK inhibitors with a related structure to Ibrutinib.

Off-Rate Assay [00188] The irreversible nature of compounds was determined using an off-rate assay utilising the TR-FRET based LanthascreenTM binding assay (Invitrogen) described above.

bnM Recombinant BTK kinase, inhibitor and 2nM LanthascreenTM Eu anti-His Antibody were incubated in a total volume of 30pl in lx LanthascreenTM Kinase Buffer A for one hour. The reaction was then diluted 33-fold into a saturating concentration of Kinase Tracer 236 in a half-area 96-well assay plate and the TR-FRET signal was measured at regular intervals over three hours. The concentration of inhibitor to be incubated with kinase was determined by calculating 40X Ki, where the Ki for each compound was calculated using the IC50 from the LanthascreenlM binding assay in the following equation, i(= (IC50)! (1+([Tracer]!Kd)) [00189] Controls were performed in the absence of inhibitor and in the absence of kinase and positive controls consisted of using 40X Ki of known reversible and irreversible BTK kinase inhibitors. The no kinase control values were then subtracted from each value for each time point and these values were calculated as a percentage of the no inhibitor control at each time point.

BTK In Vitro Inhibitory Activity [00190] The BTK kinase activity was determined using the Omnia® assay (Invitrogen) that utilises a chelation enhanced fluorophore (CHEF) incorporated into a peptide substrate.

Phosphorylation of the peptide by a kinase results in increased fluorescence and so the increase in fluorescence can be used as a measure of kinase activity. 1 5OnM recombinant BTK kinase (Invitrogen) and inhibitor were pre-incubated for 30mm in 1X Kinase Reaction Buffer before transferring lOp1 of this into 30pl of Omnia master mix to give final concentrations of 37.5nM BTK, 0.2mM DTT, 1 OpM Omnia® peptide and 0.1mM ATP (KmATP = 0.15mM). Measurements were performed in half-area 96-well assay plate and the fluorescence was read in a kinetic manner on a plate reader with an excitation wavelength of 360nm and detection wavelength of 485nm.Controls were performed in the absence of kinase and the fluorescence values from these wells were subtracted from each of the test wells at each time point. The initial velocity (0-1 5mm) was then determined from the slope of a plot of relative fluorescence units plotted against time (in seconds) and the velocities were then plotted against the inhibitor concentration to estimate the IC50 from log[lnhibitor] vs response using the Variable Slope model in Graphpad prism from Graphpad software (SanDiego, Calif).

BTK Cellular Assay [00191] Compounds were assayed in Ramos human Burkitt Lymphoma cells. Ramos cells were grown in suspension in 1225 flasks, centrifuged and re-suspended in serum-free media. Cells were then plated at 1.Sxl 06/ml in serum-free media and varying concentrations of compound and incubated for 2 hours at 37°C. Cells were then stimulated for 10 mm in 5pg/ml goat F(ab')2 Anti-Human 1gM (Invitrogen) to activate B-cell receptor signalling. The cells were then washed once in ice cold PBS and lysed on ice in lysis buffer consisting of 150mM NaCI, 50mM Tris pH8 containing freshly added Halt Protease and Phosphatase Inhibitor Cocktails (Pierce). 1 5pg total protein from lysates was loaded onto gels and blots were probed for Total BTK and phosphorylation of BTK at Y223 using antibodies from Cell signalling Technology #3533 and #5082.
