Abstract

Schiff bases, such as nitrofurantoin or nifuroxazide, are commonly applied in medicine as antibacterial agents. They are well known for their biological application as antibacterial, antifungal, antiviral, anti- HIV, anti-protozoal, anti-cancer agents. The present paper describes the synthesis of Schiff‟s base 3,4,5-trimethoxy-N- [substituted(Aryl/Hetero-Aryl)methylene)benzenamine derivatives 5am from commercially available gallic acid. These derivatives were synthesized by condensation with 3,4,5-trimethoxyanline using various aromatic and hetero-aromatic aldehydes in presence of ZnO Nano particles at room temperature. Furthermore, the present paper describes the green metrics evaluation data for the synthesized Schiff‟s base derivatives (5a-m) and its associated intermediates. In addition to the above, these compounds were screened for their antibacterial activity.
