Description

Biochem/physiol Actions

Antifungal against certain species of mold fungi and a superior antibiotic than streptomycin against M. tuberculosis by targeting AHAS catalytic subunit IlvB1.

Originally isolated from Aspergillus candidus Link, Chlorflavonin is a non-cytotoxic (up to 100 μM; MRC-5 and THP-1) antibiotic with antifungal activity against certain species of mold fungi (MIC = 0.08 μg/mL against A. amstelodami, A. fumigalus, A. ochraceous; Paecilomyces variotii MIC = 2.5 μg/mL, Botrytis cinerea MIC = 5 μg/mL). Chlorflavonin also exhibits antibiotic activity against M. tuberculosis (MIC90 = 1.56 μM) by targeting acetohydroxyacid synthase (AHAS) catalytic subunit ilvB1. Chlorflavonin is superior to streptomycin against M. tuberculosis inside infected macrophages, synergizes with isoniazid and delamanid, leading to a complete sterilization in liquid cultures.
