在全球天然产物社交 (GNPS) 分子网络平台的指导下,从南极海洋来源的放线菌埃及诺卡氏菌 HDN19-252 中获得了四种新的蒽醌衍生物,即盐醌 G−I (1–3) 和赫拉霉素 E (4)。通过广泛的 NMR、MS 和 ECD 分析阐明了它们的结构,包括绝对构型。化合物 1 和 2 对 6 种测试的细菌菌株(包括耐甲氧西林凝固酶阴性葡萄球菌 (MRCNS))表现出良好的抑制活性,MIC 值范围为 3.1 至 12.5 μM。
Four new anthraquinone derivatives, namely saliniquinones G−I (1–3) and heraclemycin E (4), were obtained from the Antarctic marine-derived actinomycete Nocardiopsis aegyptia HDN19-252, guided by the Global Natural Products Social (GNPS) molecular networking platform. Their structures, including absolute configurations, were elucidated by extensive NMR, MS, and ECD analyses. Compounds 1 and 2 showed promising inhibitory activity against six tested bacterial strains, including methicillin-resistant coagulase-negative staphylococci (MRCNS), with MIC values ranging from 3.1 to 12.5 μM.
