Abstract:
Chaetoglocins A-D (1- 4), four new secondary metabolites, were isolated from the solid-fermentation culture of Chaetomium globosum (strain no. IFB-E036), an endophytic fungus residing inside the root of Cynodon dactylon. The structures of these compounds were elucidated on the basis of detailed spectroscopic evidence and by comparing spectroscopic data with those in the literature. Compounds 1 and 2 displayed antimicrobial activity against the gram-positive bacteria with minimum inhibitory concentrations (MIC) between 8 and 32 µg/mL.
