N-substituted (S)-5-[1-(2-methoxymethylpyrrolidinyl)sulfonyl]isatin derivatives has been synthesized and tested as inhibitors of caspases-3 and -7, which are known to be downstream enzymes critical in the execution of apoptosis. N-Propyl- and N-butyl isatins, as well as the corresponding terminal alcohols and regioisomeric fluorobutyl derivatives were shown to be excellent inhibitors having different binding
已合成并测试了一系列新的N-取代的(S)-5- [1-(2-(甲氧基甲基吡咯烷基)磺酰基] isatin衍生物,作为caspases-3和-7的抑制剂,已知它们是caspase-3和-7的关键酶。执行细胞凋亡。N-丙基-和N-丁基靛红,以及相应的端基醇和区域异构的氟丁基衍生物被证明是优秀的抑制剂,对caspases-3和-7具有不同的结合力。相反,相应的氟乙基和氟丙基化合物的活性低约100-1000倍。氟化的N-苄基靛红以及三氟烷基和二氟烷基衍生物是中等抑制剂。但是,在以下位置带有不同烷基醚基的isatinsN -1作为半胱氨酸蛋白酶3和-7的抑制剂非常弱或没有活性。
