than 10 years, 1 had been considered as a promising new antibiotic compound, the reported MIC against methicillin-resistant Staphylococcus aureus (MRSA) being 37 ng/mL. After overcoming the limited availability of 1 by total synthesis (N. Slavov et al., 2010) we performed new biological tests, which did not confirm the expected degree of antibiotic activity. The observed activity of pestalone against
Pestalone(1)是由M. Cueto等人首先分离的重要海洋天然产物。在2001年,一种海洋真菌与一种海洋细菌共同发酵而来。十多年来,人们一直认为1是一种有前途的新抗生素化合物,据报道抗甲氧西林金黄色葡萄球菌(MRSA)的MIC为37 ng / mL。在通过全合成方法克服了有限的1可用性之后(N. Slavov等,2010),我们进行了新的生物学测试,该实验未能证实预期的抗生素活性。如在两个实验室中独立测定的,可观察到的鼠疫对不同的MRSA菌株的活性为3–10μg/ mL。许多合成的衍生物的1与1对MRSA和一系列植物病原体的抗性相比,包括杀虫草酰氯A和其他异吲哚啉酮(由1与胺反应形成)没有表现出更高的活性。
