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.

2-(W-HYDROXYALKYL)-6-ARYL OR HETEROCYCLIC SUBSTITUTED4,5-DIHYDROPYRIDAZIN(2H)-3-ONES OR 1-(W-HYDROXYALKYL)3-ARYL OR HETEROCYCLIC SUBSTITUTED-HEXANHYDROPRIDAZINES, E.G., 2-(4-HYDROXYBUTYL)-6-(2-THIENYL)-4,5-DIHYDROPYRIDAZIN(2H)-3-ONE OR 1-(4-HYDROXYBUTYL)-3-(2-THENYL)HEXAHYDROPYRIDAZINE, ARE PREPARED BY CONDENSING W-HYDRAZINOALKANOLS WITH ARYL OR HETEROCYCLIC-$-KETOBYTYRIC ACIDS AND ARE USEFUL AS ANTI-INFLAMMATORIES.
摘要:
WHEREIN X is methyl or chlorine and n is an integer of 1 to 5 inclusive; provided that when n is an integer of 1 to 3 inclusive, X may be the same or different and, when n is an integer of 4 or 5, each X represents chlorine. The invention relates also to some of the inorganic and trichloroacetic acid addition salts of the compounds.
