optimization on phenyl ring at the R2 site on the pyrazole displayed promising antimycobacterial activity paired with low cytotoxicity. In particular, compound 10d displayed good activity (MIC = 5.69 μg/mL) with low inhibition of CYP 2C9 (IC50 > 10 μM), consequently low potential risk of drug-drug interaction. These promising results provide new insight into the combination regimen using sulfonamide
seriously threaten agricultural production. There is an urgent need to develop novel fungicides with low toxicity and high efficiency. In this study, we designed and synthesized 44 pyrazolo[3,4-d]pyrimidin-4-one derivatives and evaluated them for their fungicidal activities. The bioassay data revealed that most of the target compounds possessed moderate to high in vitro antifungal activities. Especially compound

that compounds C13 and C14 significantly destroyed the typical structure and morphology of S. scleotiorum hyphae. In the respiratory inhibition effect assays, compounds C13 (28.0%) and C14 (33.9%) exhibited a strong inhibitory effect on the respiration rate of S. sclerotiorum mycelia, which was close to boscalid (30.6%). The results of molecular docking indicated that compounds C13 and C14 could form strong
