level of aldose reductase inhibitor activity with IC50 values of 0.45-6.0 microM. Modification of the 1-acetic acid moiety by esterification, substitution of an alpha-methyl group, or insertion of an additional methylene unit results in reduced inhibitory potency. Structure-activity data also suggests that both the benzene and 2-oxopyridine rings of 9a-e contribute substantially toward activity and that
合成了许多包含在醛糖还原酶的几种已知抑制剂中的N-酰基甘氨酸片段的2-氧代喹啉-1-链烷酸,并在大鼠晶状体测定中进行了测试。通过将合适的2-氧代喹啉中间体与卤代酯烷基化,然后将中间体酯水解,可以制备所有目标化合物。在大鼠晶状体测定中,1-乙酸衍生物9a-e显示最高水平的醛糖还原酶抑制剂活性,IC50值为0.45-6.0 microM。通过酯化,α-甲基取代或插入额外的亚甲基单元来修饰1-乙酸部分会导致抑制效力降低。
