In the present work, antioxidant activity and antimicrobial activity of Morpholinyl-4H-1,4-benzothiazines was investigated. Free radical scavenging activity was evaluated using 1,1-diphenyl-2-picrylhydrazyl(DPPH).For antimicrobial activity, Morpholinyl-4H-1,4-benzothiazines were tested for its potent antimicrobial activity against bacteria, Bacillus alkalophilus (MTCC NO=7913), Bacillus subtilis (MTCC NO=411), Bacillus flexus (MTCC NO=7024), Bacillus subtilis (MTCC NO=121), Bacillus subtilis (MTCC NO=1305) as well as their antifungal activity against Aspergillus Nigrum, Aspergillus Flexus. Thus from the results, it has been found that morpholinyl- 4H-1,4-benzothiazines consider as bioactive compounds.
