Antimicrobial and Antioxidant activities of substituted 4H-1, 4-benzothiazines

摘要

Antioxidant and antimicrobial activity of substituted benzothiazine was investigated. Antioxidant activity of 3,7-dimethyl-2-(4'-morpholinylcarbonyl)-4H-1,4-benzothiazine was tested by the use of 2-diphenyl-l-picrylhydrazyl radical(DPPH). In addition 3,7-dimethyl-2-(4'-morpholinylcarbonyl)-4H-1,4-benzothiazine was examined for its antimicrobial activity against bacteria, Bacillus subtilis, B. flexus, B. alkalophilus, as well as their antifungal activity against Aspergillus nigrum, A. Flexus and show potential antimicrobial activities.
