Abstract: Three dimensional structure-activity relationship(3D-QSAR) has been studied on a series of 6-[4-Substituted-piperazinyl) phenyl]-4,5-Dihydro-3(2H)-Pyridazinones by using.Using comparative molecular field analysis(CoMFA).The resulting CoMFA model had a cross validated coeffiecient q2 of 0.663 respectively,which showed a strong predictive ability.The 3D contour maps of CoMFA provided a smooth and interpretable explanation of the structure-antiplatelet aggregation activity relationship for the compounds.The analysis of the 3D contour plots permitted interesting conclusions about the effects of different substituent groups at the position of the N atom on the terminal of piperazidine group on the antiplatelet aggregation activity,which will guide the design of novel antiplatelet aggregation compounds with relatively high activity.
