4FJZ: Crystal Structure Of Pi3k-Gamma In Complex With Pyrrolo-Pyridine Inhibitor 63
J. Med. Chem. (2012) 55 p.7667-7685
Structure-based rational design led to the synthesis of a novel series of potent PI3K inhibitors. The optimized pyrrolopyridine analogue 63 was a potent and selective PI3Kbeta/delta dual inhibitor that displayed suitable physicochemical properties and pharmacokinetic profile for animal studies. Analogue 63 was found to be efficacious in animal models of inflammation including a keyhole limpet hemocyanin (KLH) study and a collagen-induced arthritis (CIA) disease model of rheumatoid arthritis. These studies highlight the potential therapeutic value of inhibiting both the PI3Kbeta and delta isoforms in the treatment of a number of inflammatory diseases.
