A series of heteroaryl-pyridine containing inhibitors of Akt are reported. The synthesis and structure-activity relationships are discussed, leading to the discovery of a indazole-pyridine analogue (Ki = 0.16 nM). These compounds bind in the ATP binding site, are potent, ATP competitive, and reversible inhibitors of Akt activity. No selectivity amongst the Akt isoforms is observed for this analogue, but there is good selectivity against an panel of other kinases. It is least selective for other members of the AGC family of kinases but is nonetheless 40-fold selective for Akt over PKA. The compound shows cellular activity and significantly slows tumor growth in vivo.

The structure-activity relationships of a series of isoquinoline-pyridine-based protein kinase B/Akt antagonists have been investigated in an effort to improve the major short-comings of the lead compound 3, including poor pharmacokinetic profiles in several species (e.g., mouse iv t1/2 = 0.3 h, po F = 0%). Chlorination at C-1 position of the isoquinoline improved its pharmacokinetic property in mice (iv t1/2 = 5.0 h, po F = 51%) but resulted in >500-fold drop in potency. In a mouse MiaPaCa-2 xenograft model, an amino analog 10y significantly slowed the tumor growth, however was accompanied by toxicity.
