Abstract

NEW MATERIAL:A pyridazinone derivative of formula I (R1 is lower alkyl; Z is S or methylene; X is S or NH; m is 1W3; n is 0W2).
EXAMPLE: N-Cyano-S-methyl-N'-[ 3-(3-oxo-6-phenyl-2-pyridazinyl)propyl ]isothiourea.
USE: Remedy and preventive for peptic ulcer, e.g. hyperacidity, gastric ulcer, duodenal ulcer, etc. Long duration, low toxicity, and low tendency of causing the drug- resistant state.
PROCESS: A compound of formula I wherein X is S is prepared e.g. by reacting an amine derivative of formula II with a compound of formula III (R2 is lower alkyl) in a solvent such a ethanol, acetonitrile, etc. or in the absence of solvent.
