Synthesis of novel 4,6-disubstituted quinazoline derivatives, their anti-inflammatory and anti-cancer activity (cytotoxic) against U937 leukemia cell lines☆
subsequently cyclised to obtain quinazolones 4, chlorinated 5, then hooked to various optically pure alpha-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.

Two series of somenew 2,4,6-trisubstituted-quinazoline derivatives were prepared and screened for their analgesic, anti-inflammatory activity and acute toxicity. Four compounds were more potent analgesic agents than the reference drug Indomethacin and thirteen compounds showed significant anti-inflammatory activity. Seven compounds showed combined ability to inhibit both pain and inflammation. Compounds
The reactivity of the 2-aryl-4-chloro-6-iodoquinazolines towards palladium catalyzed sequential (Sonogashira/Suzuki-Miyaura) and one-pot two-step cross-coupling (bis-Sonogashira, and successive Sonogashira/Stille) reactions to afford novel unsymmetrical polycarbo-substituted quinazolines has been evaluated. In contrast to the chloro-bromo substituted quinazolines in which selectivity has been previously
