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.
Production of chlorflavonin, a new antifungal antibiotic, by strains of Aspergillus candidus is described. Two wild strains of the fungus had distinctly different chlorflavonin-producing capabilities. One strain produced 25 mug of chlorflavonin per ml per 4 to 5 days in

The fungal genus of Aspergillus is highly interesting, containing everything from industrial cell factories, model organisms, and human pathogens. In particular, this group has a prolific production of bioactive secondary metabolites (SMs). In this work, four diverse Aspergillus species (A.
The flavonoid natural compound chlorflavonin was isolated from the endophytic fungus Mucor irregularis, which was obtained from the Cameroonian medicinal plant Moringa stenopetala. Chlorflavonin exhibited strong growth inhibitory activity in vitro against Mycobacterium tuberculosis (MIC90 1.56 μM) while exhibiting no
