1-[5-(肼基甲基亚磺酰基)戊基]-3,5-二甲基异氰脲酸酯与钴(ii)、镍(ii)和铁(iii)在H2O-DMSO介质(60 vol.% DMSO)中的组成和热力学稳定性) 通过分光光度法、电位滴定法和数学建模(CPESSP 程序)进行研究。通过 MM2 分子力学方法优化所有研究结构的几何形状,以获得 1-[5-(肼基甲基亚磺酰基)戊基]-3,5-二甲基异氰脲酸酯与钴 (ii) 配合物的配位模式的主要目标数据(估计) 、镍 (ii) 和铁 (iii)。钴 (ii) 和镍 (ii) 形成 1:1 的配合物;而铁(iii)在排除氧化还原反应的实验条件下产生1:1和1:2配合物。所有复合物都含有中性形式的配体。
Synthesis and antimycobacterial activity of novel 1,3-dimethylisocyanurate derivatives
摘要:
A series of novel 1,3-dimethylisocyanurates has been synthesized as potential inhibitors of beta-ketoacyl synthase in mycobacteria. Most of the 25 compounds described and tested for their activity against M. tuberculosis have a bacteriostatic effect, comparable and even higher that of first-line antituberculosis drugs. These compounds are nontoxic, species-specific, exhibiting no activity against other bacterial species. (C) 2012 Elsevier Masson SAS. All rights reserved.
