Piperine 유도체의 합성 및 중추억제작용에 관한 연구(I) 3,4-Methylenedioxycinnamic Acid 유도체 = Syntheses and Central Nervous Depressant Activity of Piperine Derivatives(I) 3,4-methylenedioxycinnamic Acid Derivatives

다국어 초록 (Multilingual Abstract)

Piperine was reported to have a potential central nervous system (CNS) depressant activity in mice. In order to search a more active and less toxic compound than piperine and to elucidate the active group of piperine, the aromatic amides (10 compounds) and aromatic esters (10 compounds) of 3, 4-methylenedioxycinnamic acid were synthesized and evaluated on CNS depressant activity in comparison with piperine. The pharmacological tests conducted are as follows; (1) Acute toxicity, (2) Antagonism against strychnine induced conduced convulsion, (4) Antagonism against maximal electroshock seizure, (5) Rotarod test, (6) Potentiation of hexobarbital sleeping time. It was observed that 3, 4-methylendioxycinanamic acid derivatives were less toxic than piperine, and showed no significant CNS depressant activities. These facts indicate that the piperoyl group might be concerned with the pharmacological activity of piperine.
