5-Amino-6-phenyl-1,6-dihydropyridazin-3(2H)-one

In the title compound, C10H9N3O, the pyridazinone moiety is essentially planar and forms a dihedral angle of 49.5 (1)° with the phenyl substituent. The molecular packing is stabilized by van der Waals interactions and hydr

Pyridazines. Part XXIX: Synthesis and platelet aggregation inhibition activity of 5-substituted-6-phenyl-3(2H)-pyridazinones. Novel aspects of their biological actions

A series of 6-phenyl-3(2H)-pyridazinones with a diverse range of substituents in the 5-position have been prepared and evaluated in the search for new antiplatelet agents. A significant dependence of the substituent on the inhibitory effect has been observed. The pharmacological study of these compounds confirms that modification of the chemical group at position 5 of the 6-phenyl-3(2H)-pyridazinone system influences both variations in the antiplatelet activity and the mechanism of action.

Pyridazines. XV. Synthesis of 6-aryl-5-amino-3(2H)-pyridazinones as potential platelet aggregation inhibitors

Several 3(2H)-pyridazinones with amino groups at the 5-position of the pyridazine nucleus have been prepared. The 6-aryl-5-halo-3(2H)-pyridazinones obtained from mucochloric and mucobromic acid lead to the corresponding 5- alkylamino-3(2H)-pyridazinones,
