Siccanin is an unusual, fused, phenolic pentacycle first isolated from Helminthosporium siccans and reported in 1962 as a potent antifungal agent. Siccanin inhibits succinate dehydrogenase in the terminal electron transport system. More recent studies note the proximity of the siccanin binding site to the quinone-binding site of the enzyme. Species-selective inhibition by siccanin is unique among succinate dehydrogenase inhibitors and offers a lead for new chemotherapeutics.

In Vitro Use Guide

The in vitro antifungal properties of the antibiotic siccanin were determined by the minimal inhibitory concentrations (MIC) values against 51 fungal strains (yeasts and filamentous fungi). The comparison was made with econazole, clotrimazole, 5-fluorocytosine and griseofulvin. The results show the useful antidermatophytic activity of siccanin
