SDH-IN-26

SDH-IN-26 (Compound C3) is a succinate dehydrogenase (SDH) inhibitor. SDH-IN-26 exhibits significant inhibitory activity against multiple phytopathogenic fungi, such as Rhizoctonia solani and Botrytis cinerea, with an EC50 value of 0.270 μg/mL against Rhizoctonia solani. SDH-IN-26 damages the integrity of the fungal cell membrane, increases membrane permeability, disrupts cell structure, and reduces the number of mitochondria, thus affecting the normal growth of mycelia. SDH-IN-26 leads to a decrease in mitochondrial membrane potential, and induces cell apoptosis. SDH-IN-26 is promising for research of plant diseases caused by fungi[1].
