Cercosporamide

Cercosporamide is a natural antifungal phytotoxin isolated from the Cercosporidium fungus, which infects the leaves of cassava plants. Its antifungal effect results from its selective and potent inhibition of fungal PKC-like 1 kinases (Pkc1), which are central to cell wall integrity (IC50 = 25 nM for Candida Pkc1). Cercosporamide less effectively inhibits human PKC isoforms PKCalpha, beta, and gamma (IC50s = 1.02, 0.35, and 5.8 µM, respectively), an action linked to lowering of plasma glucose in hyperglycemic mice. However, it potently inhibits MAPK-interacting kinases Mnk1 and Mnk2 (IC50 = 115 and 11 nM, respectively), reducing protein translation in cancer cells. Cercosporamide is orally bioavailable.Formal Name: (9aS)-8-acetyl-9,9a-dihydro-1,3,7-trihydroxy-9a-methyl-9-oxo-4-dibenzofurancarboxamide. CAS Number: 131436-22-1. Molecular Formula: C16H13NO7.
