In this paper, a new series of isatin-sulphonamide based derivatives were designed, synthesised and evaluated as caspase inhibitors. The compounds containing 1-(pyrrolidinyl)sulphonyl and 2-(phenoxymethyl)pyrrolidin-1-yl)sulphonyl substitution at C5 position of isatin core exhibited better results compared to unsubstituted derivatives. According to the results of caspase inhibitory activity, compound
在本文中,设计,合成和评估了一系列新的基于isatin-sulphonamide的衍生物作为胱天蛋白酶抑制剂。与未取代的衍生物相比,在靛红核的C5位上含有1-(吡咯烷基)磺酰基和2-(苯氧基甲基)吡咯烷-1-基)磺酰基取代的化合物表现出更好的结果。根据caspase抑制活性的结果,与Ac-DEVD-CHO相比,化合物20d在体外显示出对caspase-3和-7的中等抑制活性(IC 50 = 0.016±0.002μM)。在研究的化合物中,鉴定出一些活性抑制剂,IC 50值在2.33–116.91μM之间。化合物20d的活性通过分子建模研究使之合理化,该研究展示了N-苯基乙酰胺取代的额外范德华相互作用以及有效的T形π-π和π-阳离子相互作用。具有良好的半胱天冬酶抑制活性的化合物20d的引入将有助于研究人员寻找更有效的药物。
