  Discovery and optimization of 1,7-disubstituted-2,2-dimethyl-2,3-dihydroquinazolin-4(1H)-ones as potent and selective PKCθ inhibitors

  摘要：

  A high-throughput screening campaign helped us to identify an initial lead compound (1) as a protein kinase C-theta (PKC theta) inhibitor. Using the docking model of compound 1 bound to PKC theta as a model, structure-based drug design was employed and two regions were identified that could be explored for further optimization, i.e., (a) a hydrophilic region around Thr442, unique to PKC family, in the inner part of the hinge region, and (b) a lipophilic region at the forefront of the ethyl moiety. Optimization of the hinge binder led us to find 1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one as a potent and selective hinge binder, which resulted in the discovery of compound 5. Filling the lipophilic region with a suitable lipophilic sub-stituent boosted PKC theta inhibitory activity and led to the identification of compound 10. The co-crystal structure of compound 10 bound to PKC theta confirmed that both the hydrophilic and lipophilic regions were fully utilized. Further optimization of compound 10 led us to compound 14, which demonstrated an improved pharmacokinetic profile and inhibition of IL-2 production in a mouse. (C) 2016 Elsevier Ltd.
