Abstract Heating a mixture of 2-(N-alkylamino)benzoic acids, triethyl orthoformate, and ammonium acetate under solvent-free conditions generated 1-substituted 4(1H)-quinazolinones in 73−99% yields. Moreover, a possible reaction pathway was proposed. GRAPHICAL ABSTRACT
the treatment of diabetic complications. However, most of the developed small molecule inhibitors lack selectivity or suffer from low bioactivity. To address this limitation, a novel series of quinazolin-4(1H)-one derivatives as potent and selective inhibitors of AKR1B1 were designed and synthesized. Aldose reductase inhibitory activities of the novel compounds were characterized by IC50 values ranging
抑制醛糖还原酶 (AKR1B1) 是治疗糖尿病并发症的一个很有前途的选择。然而,大多数已开发的小分子抑制剂缺乏选择性或生物活性低。为了解决这一局限性,设计并合成了一系列新的喹唑啉-4(1 H )-酮衍生物作为 AKR1B1 的有效和选择性抑制剂。新型化合物的醛糖还原酶抑制活性的特征在于 IC 50值范围为 0.015 至 31.497 μM。还记录了这些衍生物显着增强的选择性,对接研究进一步支持了这一点。在这些抑制剂中,化合物5g表现出最高的抑制活性,选择性指数达到1190.8。结构-活性关系突出了 N1-乙酸和 N3-苄基在 quinazolin-4(1 H )-one 支架上具有吸电子取代基对于构建高效和选择性 AKR1B1 抑制剂的重要性。
