A series of 5-vinyl-3-pyridinecarbonitriles were synthesized and evaluated as PKC theta 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 PKC theta inhibitor with good selectivity over PKC delta.

The key intermediate, 4-chloro-5-iodo-3-pyridinecarbonitrile, allowed for ready optimization of the PKC theta inhibitory activity of a series of 3-pyridinecarbonitriles. Analog 13b with a 4-methylindol-5-ylamino group at C-4 and a 4-(2-(4-methylpiperazin-1-yl)ethoxy) phenyl group at C-5 had an IC(50) value of 7.4 nM for the inhibition of PKC theta.
