A new bafilomycin derivative () and another seven known bafilomycins (-) were isolated from feces-derived sp. HTL16. The structure of was elucidated by 1D and 2D NMR spectroscopic analysis. Biological testing demonstrated that these bafilomycins exhibited potent antiviral activities against the influenza A and SARS-CoV-2 viruses, with IC values in the nanomolar range, by inhibiting the activity of endosomal ATP-driven proton pumps.
从粪便来源的链霉菌属菌株HTL16中分离出一种新的巴弗洛霉素衍生物（）和另外七种已知的巴弗洛霉素（-）。通过一维和二维核磁共振光谱分析阐明了的结构。生物学测试表明，这些巴弗洛霉素通过抑制内体ATP驱动的质子泵的活性，对甲型流感病毒和SARS-CoV-2病毒表现出强大的抗病毒活性，IC值在纳摩尔范围内。
