cholest-5-en-7-one-thiosemicarbazone with 2,3-dichloroquinoxaline at 80 degrees C in high yield. The thiosemicarbazone derivatives were obtained by the condensation of the thiosemicarbazide with steroidal ketones. All the compounds have been characterized by means of elemental analyses, IR, 1H NMR and mass spectroscopic data. The in vitro antibacterial activity was evaluated by disk diffusion method
通过胆甾-5-烯-7-一
硫代半碳酰胺与2,3-的反应合成了一些杂环体系,即胆甾-5-烯-7-
噻唑并[4,5-b]
喹喔啉-2-基-]在80摄氏度下高产二
氯喹喔啉。
硫代
氨基
脲衍
生物是通过使
硫代
氨基
脲与甾族酮缩合而获得的。所有化合物均已通过元素分析,IR,1H NMR和质谱数据进行了表征。通过圆盘扩散法评价体外抗菌活性,然后测定化合物对大肠杆菌培养物的最小抑菌浓度(MIC)。将结果与标准药物
氯霉素进行比较。结果表明,与
氯霉素相比,化合物7和8是更好的抗菌剂。
