Ru(II)类固醇金属配合物是通过二氯二羰基钌(II)[Ru(CO)2Cl2] n与类固醇硫代半氨基甲酮的反应合成的。通过硫代半碳zone的亚硫磺和偶氮甲氮原子与Ru(II)金属进行配位。通过硫代氨基脲与甾族酮得到甾族硫代氨基脲衍生物。FT-IR,1 H NMR,13 C NMR,Fab-Mass光谱和元素分析证实了甾族硫半脲和其金属配合物的结构。这些化合物的抗菌活性首先通过圆盘扩散试验在体外对两种革兰氏阳性和两种革兰氏阴性细菌进行了测试,然后确定了最低抑菌浓度(MIC)。

We investigated the antibacterial activity of some new steroidal thiosemicarbazone and their Pd(H) metal complexes. Metal complexes were prepared from the reaction of steroidal thiosemicarbazone with [Pd(DMSO)(2)Cl-2]. Coordination via the thionic sulphur and the azomethine nitrogen atom of the thiosemicarbazone to the metal ion, the thiosemicarbazone derivatives were obtained by the thiosemicarbazide with steroidal ketones. All the compounds have been confirmed by spectral data. The antibacterial activity of these compounds was first tested in vitro by the disk diffusion assay against two gram-positive and two gram-negative bacteria, and then the minimum inhibitory concentration (MIC) was determined. The results showed that steroidal complexes are better inhibit growth as compared to steroidal thiosemicarbazones of both types of the bacteria (gram-positive and gram-negative); compound la is better antibacterial agent as compared to amoxicillin.
