title: Synthesis, spectral studies and in vitro antibacterial activity of steroidal thiosemicarbazone and their palladium (Pd (II)) complexes.
abstract: We investigated the antibacterial activity of some new steroidal thiosemicarbazone and their Pd(II) 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 Ia is better antibacterial agent as compared to amoxicillin.
