Neuropharmacology of amide derivatives of P-GABA.

Abstract:

:Three lipophilic amide derivatives of phthaloyl-GABA (P-GABA), namely gamma-phthalimido N-amyl butyramide (PGA), gamma-phthalimido-N-hexylbutyramide (PGH) and gamma-phthalimido N-phenylbutyramide (PGP), were synthesized and evaluated for their hypnotic and anticonvulsant activities in mice. Both PGA and PGH showed moderate hypnotic activity but PGP had no such action. Picrotoxin (0.08 mg/kg) a non-specific GABA antagonist completely abolished the hypnotic action of PGA in subconvulsive doses. Bicuculline (0.04 mg/kg) a GABAA antagonist, 3-mercaptopropionic acid (6 mg/kg) a GAD inhibitor at subconvulsive doses failed to neutralise the hypnotic action of PGA. On the other hand, PGA showed significant protection only against picrotoxin-induced convulsions, but was inactive against other convulsants tested. PGP which has no hypnotic activity, and has a mild anticonvulsant action in all the models except picrotoxin. A definite correlation was observed between the brain GABA and the hypnotic activity of PGA. However the present data indicate that the hypnotic and anticonvulsant activities are mediated probably through different brain GABA-ergic mechanisms.
