FR227673 and FR190293, novel antifungal lipopeptides from Chalara sp. No. 22210 and Tolypocladium parasiticum No. 16616

Abstract

Novel antifungal lipopeptides, FR227673 and FR190293, were isolated from the fermentation broths of fungal strains Chalara sp. No. 22210 and Tolypocladium parasiticum No. 16616, respectively. These compounds have the same cyclic peptide nuclear structure as FR901379, with different side chains, and showed antifungal activity against Aspergillus fumigatus and Candida albicans attributed to inhibition of 1,3-β-glucan synthesis. © Japan Antibiotics Research Association.
