摘要
在微波辐射条件下,甾酮与取代单缩二氨基硫脲经缩合反应合成了12个新型的胆酸不对称双缩二氨基硫脲衍生物(3a^3l),其结构经1H NMR,IR,ESI-MS和元素分析表征。初步抗菌活性测定结果表明:部分化合物对枯草芽孢杆菌、金黄色葡萄球菌、大肠杆菌及绿脓杆菌有一定的抗菌活性,其中,1-(2-羟基苯苄叉基)-5-[3-(3,7-二氧代-24-胆烷酸甲酯)亚甲基]二氨基硫脲(3f)对大肠杆菌的抑菌活性(IC507.40)与阿莫西林(IC507.30)相当。
Twelve novel cholic acid asymmetric bis thiosemicarbazone derivatives(3a-31) were syn- thesized by condensation of steroidal ketones with substituted thiosemicarbazides under microwave ir- radiation. The structures were characterized by 1H NMR, IR, ESI-MS and elemental analysis. Pre- liminary antibacterial activities tests indicated)that some compounds exhibited certain inhibitory activi- ties against Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomanus aeroginosa. 1- (2-Hydroxybenzylidene) -5- [ 3- (7,12-dioxo-24-cholanate) methylene ] thiocarbohydrazide (3f) showed inhibitory activities( IC50 7.40) as same as Amoxicillin( IC50 7.30) against Escherichia coli.
