We previously reported the antibacterial activity of CD437, a known antitumor compound. It proved to be a potent antimicrobial agent effective against both growing and persister cells of methicillin-resistant (MRSA). Herein, we report the synthesis of a panel of analogs and their effect on both MRSA and cancer cells. The hydrophobic group of the parent compound was varied in steric bulk, and lipid-mimicking analogs were tested. Biological assessment confirmed that the adamantane moiety is the most effective substitution for antibacterial activity, and some preferential action in cancer over MRSA was achieved.
我们之前报道了已知抗肿瘤化合物CD437的抗菌活性。事实证明它是一种有效的抗菌剂，对耐甲氧西林金黄色葡萄球菌（MRSA）的生长细胞和持留菌均有效。在此，我们报道了一系列类似物的合成及其对MRSA和癌细胞的作用。母体化合物的疏水基团在空间体积上有所变化，并对模拟脂质的类似物进行了测试。生物学评估证实，金刚烷部分是抗菌活性最有效的取代基，并且在癌细胞中相对于MRSA实现了一些优先作用。
