title: Synthesis of new 3-(3-phenyl-isoxazol-5-yl) or 3-[(3-phenyl-isoxazol-5-yl)-amino] substituted 4(3H)-quinazolinone derivatives with antineoplastic activity.
abstract: A novel series of 3-(3-phenyl-isoxazol-5-yl) or 3-[(3-phenyl-isoxazol-5-yl)amino] substituted 4(3H)-quinazolinone derivatives was synthesized. The compounds were tested for their antineoplastic activity in vitro against Raji (human Burkitt limphoma). K-562 (human chronic myelogeneous leukemia) and U937 (human histiocytic limphoma) cell lines. The most active quinazolinones showed IC50 values in the range 16-30 microM.
