Synthesis and antimicrobial activity of some new chalcones and flavones containing substituted naphthalene moiety
ABSTRACT:
Seven new chalcones and flavones containing substitued
naphthalene nucleus in their structure were synthesized and the structures of
these compounds were confirmed by spectral data. The newly synthesized
compounds were screened for antibacterial activity against Escherichia coli and
Stahylococcus aureus.
Introduction:
The flavoniods have
been reported to possess a wide range of biological activites such as antimicrobial,
anticancer, antioxidant, antinocicepative, anti-inflammatory, antihypertensive
and antifeedant. In view of these observations and in continuation of our work
on biologically active chalcones and their heterocycles, we have been planned
to synthesize the some new flavones (IIa-h) from chalcones (Ia-h) and also
studied their antibacterial activity against Escherichia coli (E. coli) and
Stahylococcus aureus (S. aureus) using Tetracycline as a standard drug.
