Synthesis and biological evaluation of oxazole derivatives as T-type calcium channel blockers
摘要:
T-type calcium channel is one of therapeutic targets for the treatment of cardiovascular diseases and neuropathic pain. In this study, as a part of our ongoing efforts to develop potent T-type calcium channel blockers, we designed oxazole derivatives substituted with arylpiperazinylalkylamines. The oxazoles were synthesized in a convenient convergent synthetic method, and biologically evaluated against alpha(1G) (Ca(V)3.1) T-type calcium channel. Among total 41 oxazole compounds synthesized, the most active one was the compound 10-35 with an IC(50) value of 0.65 mu M, which is comparable with that of mibefradil. (C) 2010 Elsevier Ltd.

Photocatalytic organic synthesis needs photocatalysts to initiate the reactions and to control the reaction paths. Available photocatalytic systems rely on electron transfer or energy transfer between the photoexcited catalysts and the substrates. We explore a concept based on the photopromoted catalyst coupling to the substrate and the phototriggered catalyst regeneration by elimination from the catalytic
