title: Synthesis and biological evaluation of some 5-ethoxycarbonyl-6-isopropylamino-4-(substitutedphenyl)aminopyrimidines as potent analgesic and anti-inflammatory agents.
abstract: Synthesis and biological evaluation of some 5-ethoxycarbonyl-6-isopropylamino-4-(substitutedphenyl)aminopyrimidines have been achieved by cyclization of N-[2-ethoxycarbonyl-2-cyano-1-(isopropylamino)vinyl] formamidine in presence of dry HCl in dioxane followed by nucleophilic substitution of 4-chloro group with substituted aromatic amine or phenoxide. Target compounds were evaluated for their analgesic and anti-inflammatory potential by known experimental models. Some of the compounds emerged out as more potent than standard drugs. Very low ulcer index was observed for the potent compounds.
