title: [The reaction of 3-(R-phenyl)-6-hydrazine pyridazines with substituted isatins (II)].
abstract: This paper presents the synthesis of six hydrazones from isatin and 1-morpholinomethyl-isatin and also of their six cooper's complex salts. Their structure was confirmed by the results of the quantitative elemental analysis and by IR, UV-VIS spectral analysis. The biological tests point out that cooper's complex salt of 3-(3'-phenyl-pyridazinylhydrazono)-5-methyl-indoline-2-one (1:2) (VI a) has the smallest toxicity (DMT over 800 mg/kg.w. p.o.), a remarkable anti-inflammatory activity (inhibition 57.1%, IAR 1.1) and also a gastroprotector coefficient of 43.3%. In the mean time, the cooper's complex salt of 3-(3'-p-anisyl-pyridazinyl-hydrazono)-5-methyl-ind oline-2-one (1:2) (VI b) has a gastroprotector coefficient of 76.3% and a lower anti-inflammatory activity than the first derivative (inhibition 36.9%).
