Abstract
The invention relates to the heterocyclic substances in particular to 3-(2-nitrosuccine aniloylhydrazon) isatine exhibiting the anti-inflammatory activity. The substance synthesized may be used in medicine. The aim consists in developing novel more active and less toxic substances of such a group. The end substances are synthesized in a reaction of hydrazine-o-nitrosuccineanylic acid with isatine in ethanol medium on heating for 2 h. The yield amounts to 92%. The gross formula is С18H15N5O5. The anti-inflammatory activity of the novel substance is 1.8-fold as high as that of indometacin. LD50 of the novel substance is 4390 mg/kg versus 47 mg/kg in indometacin.
