Abstract:
A potent and highly selective inhibitor of protein kinase C alpha has been generated via the combinatorial modification of a consensus sequence peptide. The inhibitor displays a Ki of 800 pM versus variable peptide substrate and good selectivity versus other members of the PKC family, including PKCbeta (385-fold), PKCgamma (580-fold), PKCdelta (2730-fold), PKCepsilon (600-fold), PKCeta (1310-fold), PKCtheta (1210-fold), PKCiota (940-fold), and PKCzeta (640-fold). The parallel synthesis strategy employed is easily automated and straightforward to implement.
