A series of novel pyridine carbohydrazide derivatives were synthesized from the reaction of 2-chloro-6-hydrazino-isonicotinic acid hydrazide with selected active reagents. All pre- pared compounds were tested as analgesic and anticonvulsant agents. The pharmacological screening showed that many of these compounds have good activities comparable to those of valdecoxib and carbamazepine as reference drugs.

Key words: Citrazinic Acid, Hydrazide, Hydrazones, Analgesic and Anticonvulsant Agents
