2-hydroxysaclofen

[Description]:

2-Hydroxysaclofen is a potent γ-amino-butyric-acid-B (GABAB) receptor antagonist. 2-Hydroxysaclofen can abolish nicotine-induced hypolocomotor effects and increases the antinociceptive effects. 2-Hydroxysaclofen can stimulate luteinizing hormone (LH) secretion in female rats[1][2][3].

2-Hydroxysaclofen (0.25-1 mg/kg; IP; single dosage) abolishes nicotine hypolocomotor effects and increases the antinociceptive effects of nicotine[1]. 2-Hydroxysaclofen (0.3-3 mg/kg; IP; single dosage) reduces the effects of Baclofen (a GABA receptor agonist) on d-amphetamine-induced discriminative cue[2]. 2-Hydroxysaclofen (0-100 μg/2 μl; ICV; single dosage) produces a rapid elevation in the serum LH concentration in the estrogen-primed ovariectomized rat[3]. Animal Model: Male Swiss Webster mice (22-24 g; treated with 3 mg/kg nicotine)[1] Dosage: 0.25, 0.5 and 1 mg/kg Administration: IP; single dosage; after 10 or 45 min of nicotine administration Result: Abolished nicotine hypolocomotor effects at 1 mg/kg, and increased the antinociceptive effects of nicotine at 1 mg/kg. Animal Model: Male Wistar rats[2] Dosage: 0.3, 1 and 3 mg/kg Administration: IP; single dosage Result: Reduced the effects of Baclofen on d-amphetamine-induced discriminative cue. Animal Model: Female Wistar rats (8 weeks)[3] Dosage: 0, 20, 50 or 100 μg/2 μL Administration: ICV; single dosage Result: Produced a rapid elevation in the serum LH concentration in the estrogen-primed ovariectomized rat with a dose-dependent manner, and the peak LH values were observed 10 min after the injection. The effect was dose-dependent, as 0 or 20 μg of the antagonist was ineffective while a pronounced effect was observed after the injection of 50 or 100 μg.
