Description


[0001] The present invention relates to a class of fused thiophene derivatives, and to their use in therapy. More particularly, the invention provides a family of 5,6-dihydro-1-benzothiophen-7(4H)-one derivatives, and analogues thereof, which are substituted in the 2-position by an optionally substituted morpholin-4-yl moiety. These compounds are selective inhibitors of phosphoinositide 3-kinase (PI3K) enzymes, and are accordingly of benefit as pharmaceutical agents, especially in the treatment of adverse inflammatory, autoimmune, cardiovascular, neurodegenerative, metabolic, oncological, nociceptive and ophthalmic conditions.

[0002] The PI3K pathway is implicated in a variety of physiological and pathological functions that are believed to be operative in a range of human diseases. Thus, PI3Ks provide a critical signal for cell proliferation, cell survival, membrane trafficking, glucose transport, neurite outgrowth, membrane ruffling, superoxide production, actin reorganization and chemotaxis (cf. S. Ward et al., Chemistry Biology, 2003, 10, 207-213; and S.G. Ward & P. Finan, Current Opinion in Pharmacology, 2003, 3, 426-434); and are known to be involved in the pathology of cancer, and metabolic, inflammatory and cardiovascular diseases (cf. M.P. Wymann et al., Trends in Pharmacol. Sci., 2003, 24, 366-376). Aberrant upregulation of the PI3K pathway is implicated in a wide variety of human cancers (cf. S. Brader & S.A. Eccles, Tumori, 2004, 90, 2-8). PI3K inhibitors are also described in the art, for example in WO 2006/046031.

[0003] The compounds of use in the present invention, being potent and selective PI3K inhibitors, are therefore beneficial in the treatment and/or prevention of various human ailments. These include autoimmune and inflammatory disorders such as rheumatoid arthritis, multiple sclerosis, asthma, inflammatory bowel disease, psoriasis and transplant rejection; cardiovascular disorders including thrombosis, cardiac hypertrophy, hypertension, and irregular contractility of the heart (e.g. during heart failure); neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, Huntington's disease, stroke, amyotrophic lateral sclerosis, spinal cord injury, head trauma and seizures; metabolic disorders such as obesity and type 2 diabetes; oncological conditions including leukaemia, glioblastoma, lymphoma, melanoma, and human cancers of the liver, bone, skin, brain, pancreas, lung, breast, stomach, colon, rectum, prostate, ovary and cervix; pain and nociceptive disorders; and ophthalmic disorders including age-related macular degeneration (ARMD).

[0004] In addition, the compounds of use in the present invention may be beneficial as pharmacological standards for use in the development of new biological tests and in the search for new pharmacological agents. Thus, the compounds of use in this invention may be useful as radioligands in assays for detecting compounds capable of binding to human PI3K enzymes.

[0005] The compounds of use in the present invention are potent and selective PI3K inhibitors having a binding affinity (IC50) for the human PI3Kα and/or PI3Kβ and/or PI3Kγ and/or P13Kδ isoform of 50 µM or less, generally of 20 µM or less, usually of 5 µM or less, typically of 1 µM or less, suitably of 500 nM or less, ideally of 100 nM or less, and preferably of 20 nM or less (the skilled person will appreciate that a lower IC50 figure denotes a more active compound). The compounds of the invention may possess at least a 10-fold selective affinity, typically at least a 20-fold selective affinity, suitably at least a 50-fold selective affinity, and ideally at least a 100-fold selective affinity, for the human PI3Kα and/or PI3Kβ and/or PI3Kγ and/or PI3Kδ isoform relative to other human kinases.

Moreover, if desired, a particular enantiomer may be obtained by using an appropriate chiral intermediate in one of the processes described above. Alternatively, a particular enantiomer may be obtained by performing an enantiomer-specific enzymatic biotransformation, e.g. an ester hydrolysis using an esterase, and then purifying only the enantiomerically pure hydrolysed acid from the unreacted ester antipode. Chromatography, recrystallisation and other conventional separation procedures may also be used with intermediates or final products where it is desired to obtain a particular geometric isomer of the invention.

[0100] During any of the above synthetic sequences it may be necessary and/or desirable to protect sensitive or reactive groups on any of the molecules concerned. This may be achieved by means of conventional protecting groups, such as those described in Protective Groups in Organic Chemistry, ed. J.F.W. McOmie, Plenum Press, 1973; and T.W. Greene & P.G.M. Wuts, Protective Groups in Organic Synthesis, John Wiley & Sons, 3rd edition, 1999. The protecting groups may be removed at any convenient subsequent stage utilising methods known from the art.

[0101] The following Examples illustrate the preparation of compounds according to the invention.

[0102] The compounds in accordance with this invention potently inhibit the activity of human PI3Kα and/or PI3Kβ and/or PI3Kγ and/or PI3Kδ.

Enzyme Inhibition Assays



[0103] Measurement of the ability of compounds to inhibit the lipid kinase activity of the four class 1 PI3 kinase isoforms (α, β, γ and δ) was performed using a commercially available homogeneous time-resolved fluorescence assay as described by Gray et al., Anal. Biochem., 2003, 313, 234-245, according to the manufacturer's instructions (Upstate). All assays were performed at 2 µM ATP and a concentration of purified class 1 PI3 kinase known to generate product within the linear range of the assay. Dilutions of inhibitor in DMSO were added to the assay and compared with assays run in the presence of 2% (v/v) DMSO alone (100% activity). The concentration of inhibitor required to inhibit the enzyme activity by 50% is quoted as the IC50.

[0104] When tested in the above assay, the compounds of the accompanying Examples were all found to possess IC50 values for inhibition of activity of human PI3Kα and/or PI3Kβ and/or PI3Kγ and/or PI3Kδ of 50 µM or better.

The solvent was removed in vacuo and the resulting boronic acid was combined with Example 73 (250 mg, 0.66 mmol), K3PO4 (80 mg, 0.38 mmol) and Pd(PPh3)4 (10 mg, 0.01 mmol) in DME (5.0 mL) and water (1.0 mL) and the reaction mixture was heated in a sealed tube at 140°C, under microwave irradiation, for 3 h. The reaction mixture was concentrated in vacuo and purified by column chromatography (SiO2, 20-100% EtOAc/heptane, then 15% MeOH/ DCM). The obtained solid was taken up in MeOH (5.0 mL) and was treated with a solution of HCl in Et2O (2N, 2.0 mL, 4.0 mmol). The reaction mixture was stirred at room temperature for 19 h and the solvent was removed in vacuo. The residue was partitioned between EtOAc (25 mL) and aqueous sodium hydroxide solution (2N, 25 mL). The organic phase was concentrated in vacuo and purified by column chromatography (SiO2 0-20% MeOH/DCM, 1% NH4OH) to give the title compound (61 mg, 17%) as a yellow glass. δH (DMSO-d6) 8.74 (1H, d, J 5.1 Hz), 8.04 (1H, s), 8.00 (1H, s), 7.66-7.31 (4H, m), 4.63 (2H, s), 4.01-3.98 (2H, m), 3.64-3.57 (4H, m), 3.57-3.50 (2H, m), 3.30-3.27 (2H, m), 3.02-2.93 (4H, m), 2.57 (2H, s), 2.38 (2H, s), 1.38 (9H, s), 0.96 (6H, s).
