A comparison of the anticonvulsant effects of two systemically active enkephalin analogues in rats.

Abstract:

:FK-33,824 (Tyr-D-Ala-Gly-MePhe-Met(O)-ol) and metkephamid (Tyr-D-Ala-Gly-Phe-N(Me)Met-CONH2; LY 127623) are two parenterally active synthetic analogues of the endogenous morphinomimetic pentapeptide, [Met5]-enkephalin. Acute s.c. administration of each analogue raised the seizure threshold in a dose-related manner in rats challenged with flurothyl, a volatile convulsant. The anticonvulsant action was antagonized by a low dose of naloxone (0.10 mg/kg s.c.). FK-33,824 and metkephamid can therefore be classified with typical mu-receptor agonists such as morphine and etorphine in this procedure.
