against Sclerotinia sclerotiorum, which were close to that of the positive control pyraclostrobin (0.18 μg/mL and 0.15 μg/mL). Other compounds 5f, 5k-II, 5j, 5m and 5s also exhibited strong antifungal activity. Further enzymatic assay demonstrated compound 5s inhibited porcine bc1 complex with IC50 value of 0.95 μM. The statistical results from an integrated computational pipeline demonstrated the predicted
