It was found that hist amine, cimetidine and famotidine were not inhibitory to four enzyme activities. Meanwhile, mifentidine slightly inhibited EROD and PROD activities and its derivatives IY-80843 and IY-80845 strongly inhibited PROD, EROD and ERDM activities.<\/jats:p>\n                  <jats:p>3 Prolongation of hexobarbital-induced sleeping time was determined in male ICR mice to confirm in vitro inhibito ry effects of mifentidine and its derivatives in vivo. It was observed that cimetidine, mifentidine, IY-80843 and IY- 80845 caused dose-dependent increases in the sleeping time, indicating the inhibition of P450 responsible for hexobarbital metabolism.<\/jats:p>\n                  <jats:p>4 It was concluded that mifentidine and its derivatives are P450 inhibitors and that our newly synthesized IY-80843 is most inhibitory.<\/jats:p>\n
