  Synthesis and biological activity of 3,4-dihydroquinazolines for selective T-type Ca2+ channel blockers

  摘要：

  We have synthesized 3,4-dihydroquinazoline derivatives for the potent and selective T-type Ca2+ channel blockers and evaluated for their inhibitory activities against two subtypes T-type Ca2+ channels and N-type Ca2+ channels. Among them, 5b (KYS05044, IC50 = 0.56 +/- 0.10 muM) was identified as potent T-type Ca2+ channel blocker with in vitro selectivity profile at meaningful level (T/N-type, SI = >100).

  3,4‐Dihydroquinazoline derivatives have been known to be the novel and potent T‐type calcium channel blockers. From a systematic variation of 3,4‐dihydroquinazoline derivative 5c (KYS05043), plausible SAR results were established. It was revealed that a 5‐(dimethylamino)pentylamino group at R1, a biphenyl group at R2, and a benzyl amido group at R3 in the 3,4‐dihydroquinazoline backbone are closely

  已知 3,4-二氢喹唑啉衍生物是新型有效的 T 型钙通道阻滞剂。根据 3,4-二氢喹唑啉衍生物 5c (KYS05043) 的系统变异，建立了合理的 SAR 结果。结果表明，3,4-二氢喹唑啉骨架中R1的5-(二甲氨基)戊氨基、R2的联苯基和R3的苄基氨基与通道选择性(T/N型)密切相关。以及基于 6k (KYS05090) 发现的效力。

  In order to further clarify the role of T-type Ca2+ channels in cell proliferation, we have measured the growth inhibition of human cancer cells by using our potent T-type Ca2+ channel blockers. As a result, KYS05090, a most potent T-type Ca2+ channel blocker, was found to be as potent as doxorubicin against some human cancer cells without acute toxicity. Therefore, this letter provides the biological results that T-type calcium channel is important in regulating the important cellular phenotype transition leading to cell proliferation, and thus novel T-type Ca2+ channel blocker presents new prospects for cancer treatment.
