S. Schenone et al., ARYL-3-PHENYLAMINO-4,5-DIHYDRO-2H-BENZ[G]INDAZOLES WITH ANTIARRHYTHMIC AND LOCAL-ANESTHETIC ACTIVITIES, Il Farmaco, 50(3), 1995, pp. 179-182
The synthesis of novel aryl-3-phenylamino-4,5-dihydro-2H-benz[g]indazo
les 4a-f, starting from l-3,4-dihydro-1(2H)-oxonaphtalene-2-carbothioa
mide and the proper arylhydrazines, is described. Title compounds were
evaluated for antiinflammatory, analgesic, antipyretic, antiarrhythmi
c, hypotensive, local anaesthetic and platelet antiaggregating activit
ies; some of them showed an appreciable antiarrhythmic activity in rat
s and a good level of infiltration anaesthesia in mice.
