A new bafilomycin derivative (1) and another seven known bafilomycins (2-8) were isolated from feces-derived Streptomyces sp. HTL16. The structure of 1 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 IC50 values in the nanomolar range, by inhibiting the activity of endosomal ATP-driven proton pumps.
