Popis: | In the reaction of 4,4′-diphenylmethane diisocyanate with carboxylic acid hydrazides, 4,4′-bis(1-substituted-semicarbazidyl)diphenylmethane derivatives were obtained. Depending on their chemical nature, cyclization of these compounds in alkaline medium led to the formation of two groups of compounds: bis(2,4-dihydro-3H-1,2,4-triazol-3-one) derivatives or carboxylic acids. The pharmacological effects of the selected compounds on the central nervous system in mice were investigated. Strong antinociceptive properties of some derivatives, at a wide range of doses, were observed. |
