The design, synthesis and evaluation of 3-methylene-substituted indolinones as falcipain inhibitors and antiplasmodial agents are described. These compounds react readily with thiols via an addition-elimination mechanism, indicating their potential as cysteine protease inhibitors. Several indolinones containing a Leu-i-amyl recognition moiety were found to be moderate inhibitors of the Plasmodium falciparum
描述,设计和合成的3-亚甲基取代的吲哚啉酮作为falcipain抑制剂和抗疟原虫剂。这些化合物通过加成消除机制容易与硫醇反应,表明它们作为半胱氨酸蛋白酶抑制剂的潜力。含有具有Leu-几个吲哚满酮我发现戊识别部分是适度抑制剂的恶性疟原虫半胱氨酸蛋白酶falcipain-2,但不相关的蛋白酶falcipain-3,和针对抗氯喹显示抗疟原虫活性恶性疟原虫W2在低微摩尔范围内的应变。将7-氯喹啉部分偶联至3-亚甲基取代的吲哚酮骨架上导致抗血浆活性的显着改善。
