  6-(4-Morpholino-phenyl)-4,5-dihydro-2H-pyridazine-3-ones: potent platelet aggregation inhibitors and antithrombotics

  摘要：

  A series of di- and tri-substituted 6-phenyl-4,5-dihydro-2H-pyridazine-3-ones is described. The compounds were designed to be antithrombotics and were assessed for their inhibitory properties on platelet aggregation and on thrombus formation in an arteriovenous shunt in the rat. The synthesis and physical properties of the compounds are described. The structure-activity relationships reveal that non-aromatic nitrogen-containing heterocycles can confer high activity on the 6-phenyl-pyridazinone system, provided they are combined with an additional electron-withdrawing substituent in the phenyl ring. The most potent compounds (8i, 8b) had an ED(min) of 1-3 mg/kg after oral administration in the thrombus formation test.
