摘要：
The invention provides new N-substituted 3-aminoalcoxy-6hydrazinopyridazines which have a marked anti-hypertensive activity, and a LD50 much higher than that of the clinically used drug hydralazine. The compounds of the invention are prepared by reacting 3-aminoalcoxy-6-halogenopyridazines with hydrazine.
