A novel antifungal pyrrole derivative from Datura metel leaves
2004
Phytochemical investigation of the leaves of Datura metel Linn. led to the isolation of a new pyrrole derivative 1 which was characterised as 2β-(3,4-dimethyl-2,5-dihydro-1H-pyrrol-2-yl)-1'-methylethyl pentanoate on the basis of spectral data analyses and chemical reactions. Compound 1 was endowed with antifungal activity and its MIC was found to be 87.5 μg/ml. Two proteins having molecular weights of 42 and 58 kD of Aspergillus fumigatus are potential targets for compound 1.
