A series of steroid-polyamine conjugates were synthesized and evaluated for their antimicrobial activity. This study was focused on the effect of stereochemistry at the C-3 and C-5 of steroids and types of polyamine at C-3 on activity against various human pathogens. All the conjugates exhibited strong antimicrobial activities against Gram-positive strains. Compound 18 was found to be the most potent in these series with a MIC value as low as 1 μg/mL against the bacterium Staphylococcus aureus ATCC6538P.
合成了一系列甾体-多胺缀合物，并评估了它们的抗菌活性。本研究重点研究了甾体 C-3 和 C-5 立体化学以及 C-3 位多胺类型对各种人类病原体活性的影响。所有缀合物均表现出对革兰氏阳性菌株的强抗菌活性。在这些系列中，化合物 18 的活性最强，对金黄色葡萄球菌 ATCC6538P 的 MIC 值低至 1μg/mL。
