Siccanin 화학적 특성, 용도, 생산

• 개요

  Siccanin is an inhibitor of mitochondrial complex II (succinate dehydrogenase; IC₅₀s = 0.87 and 9.3 μM for P. aeruginosa and rat mitochondria, respectively). It inhibits the growth of T. mentagrophytes (IC₅₀ = 0.3 μg/ml) via inhibition of succinate oxidation in the mitochondria. It also inhibits the growth of C. albicans strains with IC₅₀ values ranging from 5-40 and 80-90 μg/ml for aerobic and anaerobic conditions, respectively.

• 용도

  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.

• Origin

  Siccanin was found in the culture broth of Helminthosporium siccans by Sankyo Co. in 1962.
