ABSTRACT

A series of 5-vinyl-3-pyridinecarbonitriles were synthesized and evaluated as PKCtheta inhibitors. The systematic optimization of 4-[(4-methyl-1H-indol-5-yl)amino]-5-[(E)-2-phenylvinyl]-3-pyridinecarbonitrile 3 resulted in the identification of compound 23e as a potent PKCtheta inhibitor with good selectivity over PKCdelta.
