Progabide (SL 76002) 是一种 γ-氨基丁酸受体 (GABA) 激动剂。
Progabide is a gamma-aminobutyric acid receptor (GABA) agonist.
Progabide is a gamma-aminobutyric acid receptor (GABA) agonist. Doses of 50, 100 and 200 mg/kg Progabide given IP to male Wistar rats increase the plasma corticosterone levels by 244, 365 and 476% respectively (t=6.44 to12.55, p<0.01). 10 mg/kg of Progabide fails to change the concentration of corticosterone in plasma (t=0.76, N.S.). The increased plasma corticosterone level induced by administration of 200 mg/kg Progabide is evident 30 (t=2.625, p<0.05), 60 (t=13.13, p<0.001) and 120 min (t=4.07, p<0.01) after drug injection, but returns to the control value 240 min after drug injection (t=0.86, N.S.). The greatest corticosterone rise (compare with the corresponding control) is reached 60 min following the administration of Progabide[1].

Animal experiment: | Male Wistar rats weighing 170 to 240 g are caged in groups of three under diurnal lighting conditions with free access to food and water. The rats are accustomed to handling (housing 1 per cage for 30 min, injecting with saline, 1 mL/100 g body weight) in the period of 7 days before the beginning of the experiment. Progabide is injected as a suspension in saline containing 0.1% Tween 80. Control rats are treated IP with the corresponding vehicle (1 mL/100 g body weight). Ether stress is performed and 15 min after the beginning of the stressful procedure the animals are sacrificed[1]. |
