tropica KWH23 parasite, and the cytotoxicity level was also measured on human macrophage blood cells. It was observed that IC50 of the antimonials was 100‐fold superior as compared with the standard antimonial drug used. Cytotoxicity results showed that these antimonials are highly active even at low concentrations and are biocompatible with human macrophages, making them highly promising drug candidates
为了寻找可安全治疗利什曼病等寄生虫病的新药,合成了一系列[SbR 3(OOCR')2 ]型杂合五价
锑,并使用元素分析,傅里叶变换红外光谱和多核(1 H和13 C)NMR光谱。
羧酸根部分主要是取代的
苯甲酸酯,带有一些适合于乙酰或
尼古丁配体的配合物。[Sb(p- Tol)3(p- CH 3 C 6 H 4 COO)2 ],[Sb(p- Tol)3(3,5-Cl 2 C 6 H 3 COO)2 ]和[Sb(p- Tol)3(3-nicotinato)2 ]的晶体学测定结果表明,采用的几何形状介于三角锥和方形锥之间,基本上是单体具有五个协调的Sb中心。评估了对热带利什曼原虫KWH23寄生虫的杀利什曼活性,并且还测定了对人巨噬细胞血细胞的细胞毒性
水平。观察到IC 50与所使用的标准
锑药相比,这种抗生素的使用率高出100倍。细胞毒性结果表明,即使在低浓度下,这些
锑也具有很高的活性,并且与人巨噬细胞具有
