Its structure was elucidated by detailed spectroscopic analysis. Compound 1 exhibited moderate inhibitory activity （IC50= 13.7 μmol·L^-1） against protein tyrosine phosphatase 1B （PTP1B）, a key target for the treatment of type 2 diabetes, representing the first report of PTP1B inhibitory activity for sarsolenane diterpenes. This discovery promotes computational prediction of binding mode between the enzyme and the metabolite, suggesting a crucial role of the residues Tyr46, Ser216 and Arg221 in the binding action.展开更多
