The novel derivatives of the nicotinic acid, having general formula:
wherein R1 is H or methyl and R2 and R3, when separated, respectively represent OH and CH20H, or are combined in a cyclic structure forming the group:
show analgesic and anti-inflammatory activity associated with specific effects, or hypoglycemic and hypochloles- teremic activity. The subject derivatives are prepared by reacting (3-4) isopropyliden pyridoxine with the chloride of the nicotinic acid.
