N-Phthaloyl gamma-aminobutyric acid, a new gamma-aminobutyric acid derivative synthesized in this laboratory, has been found to possess anticonvulsant, antinociceptive and antistress activities. Effects of this derivative on gastric lesions induced by aspirin and ethanol were studied in rats. N-Phthaloyl gamma-aminobutyric acid significantly inhibited both(More)
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(More)
A new derivative of gamma-aminobutyric acid (GABA) was synthesized. The compound, N-octanoyl GABA (O-GABA), exhibited positive analgesic response in four different models in mice--tail immersion, hot plate, tail clip and acetic acid induced writhing. The antinociceptive activity was significantly blocked by picrotoxin but not by bicuculline or(More)
The effect of immobilization restraint stress (RS) on some biochemical and biophysical parameters in rats and their modulation by N-phthaloyl gamma-aminobutyric acid (P.GABA) was studied. RS did not affect the levels of serum Ca2+, inorganic phosphate, bilirubin, total protein, but caused insignificant increase of albumin level and significantly decreased(More)
A new gamma-aminobutyric acid derivative synthesised in this laboratory, N-octanoyl gamma-aminobutyric acid was found to possess antinociceptive activity but no anticonvulsant activity. The effect of the compound on gastric lesions produced by aspirin, ethanol and stress in rats, was studied and the compound was found to possess effective antiulcer action.(More)
Out of fourteen compounds reported here only four [N-valproyl GABA (V.GABA), N-phthaloyl GABA (P.GABA), gamma-phthalimido N-amyl butyramide (PGA) and gamma-phthalimido N-phenyl butyramide (PGP)] gave significant protection to all the four components of maximal electroshock-induced seizures (MES) in mice. It appeared that substitution of either amino or(More)
