Aldose reductase (AR) is a crucial enzyme of the polyol pathway through which glucose is metabolized under conditions of hyperglycemia related to diabetes. A series of novel acetic acid derivatives containing quinazolin-4(3H)-one ring (1–22) was synthesized and tested for in vitro AR inhibitory effect. All the target compounds exhibited nanomolar activity against the target enzyme, and all compounds
醛糖还原酶(AR)是多元醇途径中的关键酶,在与糖尿病相关的高血糖条件下,葡萄糖通过该途径代谢。合成了一系列含有喹唑啉-4(3 H )-单环( 1-22 )的新型乙酸衍生物,并测试了其体外AR抑制作用。所有目标化合物均表现出针对目标酶的纳摩尔活性,并且与参比药物依帕司他相比,所有化合物均表现出更高的活性。其中,化合物19,命名为2-(4-[(2-[(4-甲基哌嗪-1-基)甲基]-4-氧代喹唑啉-3(4H ) -亚氨基)甲基]苯氧基)乙酸,显示出抑制作用最强,K I值为 61.20 ± 10.18 nM。此外,还使用 MTT 测定研究了这些化合物针对 L929(非肿瘤成纤维细胞)和 MCF-7(乳腺癌细胞)的活性。化合物16和19对正常L929细胞显示出较低的毒性。还评估了合成化合物(1-22)的吸收、分布、代谢和排泄特性。分子对接模拟被用来研究这些抑制剂对抗 AR 的可能结合机制。
