Abstract

A series of 2-amino-3-cyano-4-alkyl-6-(2-hydroxyphenyl)pyridine derivatives was synthesized and evaluated as IkappaB kinase beta (IKK-beta) inhibitors. Substitution of an aminoalkyl group for the aromatic group at the 4-position on the core pyridine ring resulted in a marked increase in both kinase enzyme and cellular potencies, and provided potent IKK-beta inhibitors with IC(50) values of below 100 nM.
