based drug design approach is well known recent medicinal chemistry to design anti-parasitic agents. In the present study, we have designed a series of (1-phenyl-9H-pyrido [3,4-b]indol-3-yl) (4-phenylpiperazin-1-yl)methanone derivatives using molecular hybridization approach. Designed analogues were evaluated for cytotoxicity and inhibition activity against Leishmania infantum and Leishmania donovani
分子杂交是一种基于配体的药物设计方法,是近来众所周知的用于设计抗寄生虫剂的药物化学。在本研究中,我们使用分子杂交方法设计了一系列(1-苯基-9 H-吡啶并[3,4-b]吲哚-3-基)(4-苯基哌嗪-1-基)甲酮衍生物。评价设计的类似物对婴儿利什曼原虫和多形利什曼原虫的细胞毒性和抑制活性。在这些报告的类似物7b,7d,7e,7f和7m中显示出对婴儿乳酸杆菌和donovani乳酸菌的强力抑制作用。化合物7i和7k表现出对L. donovani的选择性抑制作用。特别地,化合物7e和7k分别显示出对婴儿乳杆菌和多诺氏乳杆菌的最有效的抗leishmanial活性。这些化合物的抗Leishmanial活性与标准药物miltefosine和pentamidine相当。SAR研究表明,建议将苯环上的给电子基团取代用于有效的抗Leishmanial活性。
