Hansch analysis of veratric acid derivatives as antimicrobial agents
The synthesis, characterization and antimicrobial evaluation of a new series of veratric acid derivatives are presented. Preliminary in vitro antimicrobial activity of the title compounds was assessed against a panel of microorganisms including Gram-positive and Gram-negative bacteria and fungi. Some of the veratric acid derivatives exhibited significant in vitro antimicrobial activity. QSAR investigation applied to find a correlation between different physicochemical parameters of the veratric acid derivatives and their antimicrobial activity indicated the importance of topological parameters in describing the antimicrobial activity.
Reaction of Sulphuryl Chloride with Some Schiff Bases
The reaction of sulphuryl chloride with schiff bases has been studied.In each case, pure crystalline products have been isolated, and their structures elucidated on the basis of IR, PMR and mass spectral data.A plausible mechanism is advanced for the formation of observed products.
