|Abstract:||Condensation of 1,8-naphthyridin-2-one-3-carboxylic acid hydrazide 1 with different isatins 2 gives the corresponding isatin-β-(1,8-naphthyridin-2-one-3-carbonylhydrazones) 3, which on treatment with cone. H2SO4 undergo cyclodehydration to afford the desired 2-(1,8-naphthyridin-2-one-3-yl)-[1,3,4]oxadiazino[6,5-b] indoles 4. On the other hand, the reaction of 1 with different acetophenones furnished the respective acetophenone 1,8- naphthyridin-2-one-3-carbonylhydrazones 5. The structural assignment of the products is based on elemental analyses and spectral data. The compounds 4 and 5 have been evaluated for their antibacterial activity against E. coli, P. aeruginosa, B. subtilis and B. mycoides.|
