title: Second generation 4-(4-methyl-1H-indol-5-ylamino)-2-phenylthieno[2,3-b]pyridine-5-carbonitrile PKCtheta inhibitors.
abstract: Thieno[2,3-b]pyridine-5-carbonitrile 16 with a 4-methyl-5-indolylamine at C-4 and a 5-methoxy-2-(dimethylamino)-methylphenyl group at C-2 had an IC(50) value of 16 nM for the inhibition of PKCtheta. While moderate inhibition of PKCdelta was also observed (IC(50)=130 nM), 16 had IC(50) values of greater than 5 microM against Lyn and other members of the Src kinase family.
