  3,4-Dihydroquinazoline derivatives as novel selective T-type Ca2+ channel blockers

  摘要：

  For LVA T-type Ca2+ channel blockers, 3,4-dihydroquinazoline derivatives as new scaffolds were prepared and evaluated for the inhibitory activity against two members of the recombinant T-type Ca2+ channel family. Among them, 8a (KYS05001, IC50 = 0-9 muM) was nearly equipotent with mibefradil (IC50 = 0.84 muM) and inhibited LVA T-type Ca2+ channel with greater efficacy than HVA Ca2+ channel.

  日期：1997.12

  A novel, facile and efficient method for the synthesis of aryl iminophosphorane has been developed by treating a series of Ar-NH2 (1) attached to a solid support with Ph3P and diethyl azodicarboxylate at room temperature. The resulting solid-supported cinnamyl iminophosphorane (4) was treated with an aryl isocyanate to generate the corresponding solid-supported carbodiimide (5), which upon exposure to a secondary amine underwent 1,2-addition followed by an intramolecular Michael addition to afford the desired 3,4-dihydroquinazoline (7).
