BANERJEE, Mrityunjay et al. Synthesis and biological evaluation of some anthranilic acid and 2-phenylquinazoline-4(3H)-one analogues. S.Afr.j.chem. (Online) [online]. 2009, vol.62, pp. 134-142. ISSN 1996-840X.
In the present investigation a novel series of N-(phenyl) chalconyl anthranilic acids containing pyrazolines (4a-j), tetra-hydropyrimidines (4k-o), tetrahydrothiopyrimidines (4p-t) and 2-phenylquinazolin-4(3H)-ones containing pyrazolines (8a-f), isoxazolines (8g-l), tetrahydropyrimidines (8m-r) and tetrahydrothiopyrimidines (8s-x) were synthesized and characterized by elemental analysis, FT-IR, 1H NMR and mass spectroscopy. The title compounds (4a-t) and (8a-x) were investigated for their analgesic, anti-inflammatory, antimicrobial and in vitro protein denaturation activities. Compounds 4j and 8x were identified as lead compounds with optimum analgesic, anti-inflammatory and antimicrobial activities.
Keywords : Quinazolines; antimicrobial; analgesic; anti-inflammatory; protein denaturation.
