preliminary knowledge about their possible mechanism of action, the inhibition of trypanothione reductase (TryR) was measured. Among these novel structures, compounds 1h (3,5-dimethyl-4-isoxazolyl selenocyanate) and 2d [3,3'-(diselenodiyldimethanediyl)bis(2-bromothiophene)] exhibited good association between TryR inhibitory activity and antileishmanial potency, pointing to 1h, for its excellent theoretical
合成了一系列带有有趣生物活性支架(喹啉,喹喔啉,a啶,色烯,呋喃,异is唑等)的新型硒代异氰酸酯和二硒化物,它们在体外对利什曼原虫amastigotes有杀菌作用,并在人类THP-1细胞中具有细胞毒性。被确定。有趣的是,大多数测试化合物在低微摩尔范围内均具有活性,这使我们鉴定出四种前导化合物(1h,2d,2e和2f),其50%有效剂量(ED50)值在0.45至1.27μM之间,并且选择性指数>所有这些都为25,远高于参考药物的观测值。对这些活性衍生物进行了抗感染巨噬细胞的评估,为了初步了解其可能的作用机理,测量了锥虫硫醚还原酶(TryR)的抑制作用。在这些新颖的结构中,化合物1h(3,5-二甲基-4-异恶唑基硒酸酯)和2d [3,3'-(二硒基二甲基二甲烷二基)双(2-溴噻吩)]表现出TryR抑制活性和抗菌性之间的良好联系,这表明1h,由于其优异的理论ADME(吸收,分布,代谢和排泄)特性
