Synthesis, Characterisation and Biological Screening of s-Triazine Based Chalcones and its Derivatization into Phenyl Pyrazolines, Isoxazoles

Full Text PDF

Abstract:

Heterocyclic derivatives such as phenyl pyrazolines and isoxaxoles were prepared from s - triazine based chalcones. Chalcones (A1 - A5) are synthesised by the reaction of compound (V) with various aromatic aldehydes. Moreover, further reaction of chalcones with phenyl hydrazine hydrochloride and hydroxylamine hydrochloride in the presence of alkali gives phenyl pyrazolines (A6 - A10) and isoxazoles (A11 - A15) derivatives respectively. The structures of the newly synthesised compounds were confiremed by spectroscopic (IR, 1H NMR, 13C NMR) and elemental analysis. All the newly synthesised compounds have been screened for their antimicrobial activity against selected Gram - positive (S. aureus and S. pyogenus), Gram - negative (E. coli and P. aeruginosa) bacterial and fungal strains (C. albicans, A. niger and A. clavatus).
