Discovery of 3-(1H-indol-3-yl)-4-[2-(4-methylpiperazin-1-yl)quinazolin-4-yl]pyrrole-2,5 -dione (AEB071), a potent and selective inhibitor of protein kinase C isotypes.
J Med Chem. 2009 Oct 22;52(20):6193-6.
A series of novel maleimide-based inhibitors of protein kinase C (PKC) were designed, synthesized, and evaluated. AEB071 (1) was found to be a potent, selective inhibitor of classical and novel PKC isotypes. 1 is a highly efficient immunomodulator, acting via inhibition of early T cell activation. The binding mode of maleimides to PKCs, proposed by molecular modeling, was confirmed by X-ray analysis of 1 bound in the active site of PKCalpha.
