SYNTHESIS AND IN-VIVO ACTIVITY OF NOVEL ANTIHYPERTENSIVE AGENT BASED ON PYRIDAZINE SCAFFOLD
AbstractThe main objective of the present research work to synthesize, characterization, and in-vivo evaluation of Pyridazine derivatives. To study the different synthesized derivatives by using different analytical parameters like IR, Mass, and NMR analysis. And also find out the antihypertensive activity. The studies on the hydralazine group drugs led to the synthesis of many Pyridazine derivatives with a wide activity spectrum on the cardiovascular system. Pyridazine derivatives, a class of compounds containing the N-N bond, exhibit a wide range of pharmacological activities such as antidepressant, antihypertensive, and cardiotonic, etc. Some 6-(substituted phenyl)-2-(substituted methyl)-4,5-dihydropyridazin-3(2H)-one derivative was synthesized by reacting 6-Phenyl substituted 2,3,4,5-Tetrahydro pyridazin-3-one with cyclic secondary amine under Mannich reaction conditions. A total of twenty compounds (vj1-vj20) were synthesized under Mannich reaction conditions. Out of twenty compounds, around six derivatives were selected for evaluation of antihypertensive activities by a non-invasive method using the Tail Cuff method. Most of the compounds showed good antihypertensive activity. Few compounds like vj3, vj6, vj9, vj14, vj19, and vj20 were found to show a highly significant reduction in mean arterial blood pressure but at a higher dose in comparison to standard drugs like propanolol and hydralazine. The substituted pyridazine derivatives discovered in this study may provide valuable therapeutic intervention for the treatment of hypertension.
