The synthesis and pharmacological activities of a new series of piperazinyl quinazolin-4-(3H)-one derivatives acting toward the α2δ-1 subunit of voltage-gated calcium channels (Cavα2δ-1) are reported. Different positions of a micromolar HTS hit were explored, and best activities were obtained for compounds containing a small alkyl group in position 3 of the quinazolin-4-(3H)-one scaffold and a 3-m
报道了一系列作用于电压门控钙通道 (Ca v α2δ-1) α2δ-1 亚基的新系列哌嗪基喹唑啉-4-(3 H )-one 衍生物的合成和药理活性。探索了微摩尔 HTS 命中的不同位置,并获得了在 quinazolin-4-(3 H )-one 支架的位置 3 和 3-methyl-piperazin-1-yl- 中含有小烷基的化合物的最佳活性或位置 2 的 3,5-二甲基-哌嗪-1-基-丁基。活性显示在位置 2 的链的R对映异构体中,并且几个 eutomers 达到个位数纳摩尔亲和力。中央支架的最终修饰以降低亲脂性提供了吡啶并[4,3- d]pyrimidin-4(3 H )-one 16RR ,它对 Ca v α2δ-1 和 Ca v α2δ-2表现出高选择性,这可能与其在小鼠中比普瑞巴林提高的镇痛功效-安全比有关。
