Structure-based design of isoquinoline-5-sulfonamide inhibitors of protein kinase B

Structure-based drug design of novel isoquinoline-5-sulfonamide inhibitors of PKB as potential antitumour agents was investigated. Constrained pyrrolidine analogues that mimicked the bound conformation of linear prototypes were identified and investigated by co-crystal structure determinations with the related protein PKA. Detailed variation in the binding modes between inhibitors with similar overall conformations was observed. Potent PKB inhibitors from this series inhibited GSK3β phosphorylation in cellular assays, consistent with inhibition of PKB kinase activity in cells.

PHARMACEUTICAL COMPOUNDS

The invention provides compounds for the prophylaxis or treatment of a disease state or condition mediated by protein kinase A or protein kinase B, the compounds having the formula (I°), or being salts or solvates thereof. In formula (I°), n is 0 or 1; A and E are alkylene 2-3 carbon atoms in length optionally substituted by R11 and -X-CH(R6)(R7); G is hydrogen when n is 0 and, when n is 1, G is hydrogen or -X-CH(R6)(R7); R1 is an aryl or heteroaryl group having 5-12 ring members; R2 and R4 are selected from hydrogen, R7,R11 and CH(R6)(R7); R3, R3a and R5 are selected from hydrogen, R11 and -X-CH(R6)(R7); or any one pair or any two non-overlapping pairs selected from R2 and R3; R3 and R4; R2 and R5; R3 and R5; R4 and R5; R3 and R8; and R4 and R8 are linked together in a ring and together form an alkylene chain of 1-5 carbon atoms in length which may be optionally substituted by R11 and -X-CH(R6)(R7); or the pair R2 and R4 are linked together in a ring and together form an alkylene chain of 2-5 carbon atoms in length which may be optionally substituted by R11 and -X-CH(R6)(R7); and optionally R3 and R3a may be linked together in a ring and together form an alkylene chain of 1-6 carbon atoms in length which may be optionally substituted by R11 and -X-CH(R6)(R7); or R6 and R7 together with the carbon atom to which they are attached form a cyclic group having 5-12 ring members; X, R6, R7, R8, R9, R10 and R11 are each as defined in claim 1; and wherein the definitions of, A, E, G, X, n and R1 to R11 are subject to the provisos set ou in claim 1.
