Abstract:
2-aryl-4-quinolones are converted into phosphates by reacting with tetrabenzyl pyrophosphate to form dibenzyl phosphates thereof, which are then subject to hydrogenation to replace dibenzyl groups with H, followed by reacting with Amberlite IR-120 (Na+ form) to form disodium salts. The results of preliminary screening revealed that these phosphates showed significant anti-cancer activity. A novel intermediate, 2-selenophene 4-quinolone and Λ/, Λ/-dialkylaminoalkyl derivatives of 2-phenyl-4-quinolones are also synthesized. These novel intermediates exhibited significant anticancer activities.

Abstract:
Two series of 6,7,2′,3′,4′,5′-substituted 2-phenyl-4-quinazolinones and 6,2′,3′,4′,5′-substituted 2,3-dihydro-2-phenyl-4-quinazolinones are synthesized and evaluated for cytotoxicity against a panel of human tumor cell lines, such as epidermoid carcinoma of the nasopharynx (KB), lung carcinoma (A-549), ileocecal carcinoma (HCT-8), breast cancer (MCF-7), melanoma (SKMEL-2), ovarian cancer (1A9), glioblastoma (U-87-MG), bone (HOS), P-gp-expressing epidermoid carcinoma of the nasopharynx (KB-VIN), and prostate cancer (PC3) cell lines, and some of the compounds are found potent. The present invention also synthesizes 2-phenyl-4-alkoxy-quinazoline compounds, wherein some of the compounds exhibit antiplatelet activity.
