In order to search a more active and safer compound, piperine derivatives with substituents in piperidine residue were synthesized and evaluated on CNS depressant activity. N-Piperoyl-2-methylpiperidine (I) and N-piperoyl-3-methylpiperidine (II) were potent in strychnine-induced convulsion. Compound I and N-piperoyl-3-hydroxypiperidine (IX) exhibited a potent inhibitory effect against pentetrazole induced convulsion and a significant prolongation effect of hexobarbital-induced sleeping time. The hydroxy derivatives were more toxic than the methyl derivatives.
