The first synthesis of octapeptin C4 was achieved using a combination of solid phase synthesis and off-resin cyclisation. Octapeptin C4 displayed antibiotic activity against multi-drug resistant, NDM-1 and polymyxin-resistant Gram-negative bacteria, with moderate activity against Staphylococcus aureus. The linear analogue of octapeptin C4 was also prepared, which showed reduced activity.
八肽菌素C4的首次合成是通过固相合成和脱树脂环化相结合的方法实现的。八肽菌素C4对多重耐药、NDM-1和耐多粘菌素的革兰氏阴性菌具有抗菌活性,对金黄色葡萄球菌具有中等活性。还制备了八肽菌素C4的线性类似物,其活性有所降低。
