Abstract
A series of novel 4-aryl-8-arylidene-5,6-dihydro-2-imino-6-methoxy-4H,7H-[3,1] benzothiazines were synthesized and structures were elucidated by UV, IR, 1H NMR and Mass spectral data. These compounds were screened for their antibacterial activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa. The compounds were also screened for their antifungal activity against Aspergillus niger and Candida albicans. The antibacterial and antifungal results are compared against standard reference Ampicillin and Amphotericin B respectively.
