Antifungal agent 129 (Compound 4g) is an inhibitor targeting Rhizoctonia solani, with an EC50 value of 4.27 mg/L. It has a good control effect against rice sheath blight in in vitro and in vivo experiments. Preliminary exploration through scanning electron microscopy, molecular docking, enzyme activity determination, and cytotoxicity experiments has revealed that Antifungal agent 129 may exert its inhibitory activity by affecting the cell structure or physiological processes of Rhizoctonia solani. Antifungal agent 129 can be used in the research of plant diseases in the agricultural field, such as rice sheath blight, which are caused by Rhizoctonia solani[1].
