SDH-IN-12 (compound 9b), a succinate dehydrogenase inhibitor, shows activity against S. sclerotiorum and C. arachidicola, with respective EC50 values of 0.97 and 2.07 μM. The compound demonstrates no significant herbicidal effects on monocotyledonous and dicotyledonous plants [1].

SDH-IN-12（50 μM）对S. sclerotiorum（98%）、Alternaria solani（71%）、B. cinerea（50%）、R. solani（90%）和C. arachidicola（90%）具有灭菌活性[1]。SDH-IN-12（10 μM）能够破坏S. sclerotiorum的超微结构，导致菌丝体表面收缩并出现明显塌陷[1]。此外，SDH-IN-12具有良好的生物利用度，血浆蛋白结合能力（PPB）< 90%[1]。
