Resumen
A series of N-[(2-chloro-7-methylquinolin-3-yl)methyl]-(substituted)-aniline/butan-1-amine/cyclohexamine
derivatives (4a-n) & N-benzyl-1-(2-chloro-7-methylquinolin-3-yl)methanamine (4o) was designed and
synthesized based on the structural requirements essential for allylamine / benzylamine antimycotics. Compounds
(4a-o) were synthesized by nucleophilic substitution reaction of 2-chloro-3-(chloromethyl)-7-
methylquinoline with substituted aromatic/aliphatic primary amine in absolute ethanol in presence of triethylamine.
The structures of all new products were confirmed by IR, 1H & 13C-NMR and mass spectral data. The
newly synthesized compounds were screened in-vitro for their antifungal activity against Aspergillus niger
MTCC 281, Aspergillus flavus MTCC 277, Monascus purpureus MTCC 369 and Penicillium citrinum NCIM
768 by cup plate method. Preliminary screening of compounds (4a-o) revealed that compounds viz. 4a, 4b, 4e,
4g, 4j and 4l showed excellent antifungal activity. Dihalogen and benzyl substituted compounds 4j, 4l & 4o exhibited
potent antifungal activity. Replacement of phenyl ring with aliphatic groups like butyl or cyclohexyl
causes substantial decrease in antifungal activity and activity decreases when phenyl ring is substituted with electron
releasing groups. Colegio de Farmacéuticos de la Provincia de Buenos Aires
