In view of the link between use of NSAIDs and altered cancer incidence and a growing evidence of COX-II implication in angiogenesis, a novel series of 4,6-disubstituted quinazoline derivatives have been synthesized starting from anthranilic acid derivatives 1 through conventional methods. Initially acylation followed by cyclisation to obtain benz-oxazinones 2 which on further treatment with ammonia yielded the crucial intermediate, 2-substituted benzamide (3). The products were subsequently cyclised to obtain quinazolones 4, chlorinated 5, then hooked to various optically pure α-amino acids to have 4,6-disubstituted quinazoline derivatives 6. All the derivatives 6 are screened for anti-inflammatory and anti-cancer activity against U937 leukemia cell lines. Some of the compounds exhibited promising anti-cancer activity with reference to standard drug Etoposide.
