Thirugnanaselvi, S. published the artcileStructural and biological activities of (4Z)-4-(3-phenyl allylidene amino)-3-hydroxy naphthalene-1-sulfonic acid (AC) and naphthalene-1-yl-thiophene-2-ylmethyleneamine (NT) as Schiff bases, Product Details of C10H9NO4S, the publication is International Journal of Chemical Sciences (2016), 14(2), 559-569, database is CAplus.
Schiff bases (4Z)-4-(3-Ph allylidene amino)-3-hydroxy naphthalene-1-sulfonic acid (AC) and naphthalene-1-yl-thiophene-2-ylmethylene-amine (NT) derived from the condensation reaction of Analar grade 1-amino-2-naphthol 4-sulfonic acid WITH Cinnamaldehyde and naphthalene-1-ylamine and thiophene-2-carboxaldehyde, resp. was prepared The synthesis was carried out under microwave condition. This Schiff base was analyzed by infra-red and UV. The all prepared compounds were assayed for antibacterial (Bacillus subtilis MTCC 441, Staphylococcus aureus MTCC 96, Echirichia coli MTCC 1689 and Proteus vulgaris MTCC 742) and antifungal (Aspergillus sp. and Candida albicans) activities by disk diffusion method. The results indicate that all tested compounds show antibacterial activity against E. coli, as gram pos. and neg. bacteria, and antifungal activity against C. albicans. But the compounds AC having 1-OH and 1-HSO3 substituted showed good inhibition against bacteria and fungi as compare to standard drugs.
