have been synthesized and evaluated for anti-leishmanial activities against L. donovani in vitro and cytotoxicity toward THP1 cells. All compounds exhibited obvious anti-leishmanial activities. Among the tested compounds, there were 10 maleimides with superior anti-leishmanial activities to standard drug amphotericin B, and 32 maleimides with superior anti-leishmanial activities to standard drug pentamidine
在本研究中,已经合成了45种马来酰亚胺,并评估了其对体外杜氏乳酸杆菌的抗利什曼活性和对THP1细胞的细胞毒性。所有化合物均表现出明显的抗利什曼活性。在所测试的化合物中,有10种具有比标准药物两性霉素B更高的抗利什曼活性的马来酰亚胺,和32种具有比标准药物戊tam具有更好的抗利什曼活性的马来酰亚胺,尤其是化合物16(IC50 <0.0128μg/ mL)和42(IC50 <0.0128μg/ mL),在体外测试中显示出非凡的功效,并且细胞毒性低(CC50> 10μg/ mL)。16和42的抗Leishmanial活性比两性霉素B强10倍。结构和活性关系(SAR)研究表明,3,与3-甲基-马来酰亚胺和3,4-二氯-马来酰亚胺相比,4-未取代的马来酰亚胺显示出最强的抗利什曼活性。与3-甲基-马来酰亚胺和3,4-非取代的马来酰亚胺相比,3,4-二氯-马来酰亚胺的细胞毒性最小。结果表明,一些已报道的
