PKC theta is a serine/threonine kinase involved in the regulation of IL2 production in T cells. It has recently become an attractive therapeutic target for a variety of immunological disorders. We describe the optimization of the enzymatic and cellular potency of a series of 5-vinyl-3-pyridinecarbonitrile inhibitors of PKC theta. A binding model was developed that explains much of the SAR observed for this series, including the enzymatic potency observed for 19. An analysis of functional potency against various physiochemical parameters suggests that cellular potency is correlated with Log D(7.4), but not with c Log P, PAMPA permeability, or TPSA.
