L-838417 是GABAA 受体 α2, α3 和 α5 亚型的选择性部分激动剂，是 α1 亚型的拮抗剂，其对 α1β3γ2、α2β3γ2、α3β3γ2、α4β3γ2、α5β3γ2 和 α6β3γ2 的Ki 值分别为 0.79 nM、0.67 nM、1.67 nM、267 nM、2.25 nM 和 2183 nM。
Ki: 0.79 nM (α1β3γ2), 0.67 nM (α2β3γ2), 1.67 nM (α3β3γ2), 267 nM (α4β3γ2), 2.25 nM (α5β3γ2) and 2183 nM (α6β3γ2).
L-838417 (1.0 mg/kg) produces anxiolytic effects in adult rat, as indexed by a transformation of social avoidance into preference and an increase in social investigation.
L-838417 (2.0 mg/kg) eliminates social avoidance, but has no anxiolytic effects on social investigation.
L-838417 (0.5 mg/kg) reverses the anxiogenic effects of prior stress regardless of age, but with doses ≥ 1 mg/kg decreases social investigation, an effect possibly due in part to locomotor-impairing effects of this compound.
| Animal Model: | Male and female adolescent and adult Sprague–Dawley rats. |
| Dosage: | 0, 0.5, 1.0, 2.0, or 4.0 mg/kg. |
| Administration: | IP. |
| Result: |
Adolescents required a higher dose (2 mg/kg) to attenuate their social avoidance.
The lowest dose of 0.5 mg/kg was sufficient to reverse the anxiogenic effects of repeated restraint as reflected by a significant increase in the coefficient relative to vehicle-treated animals. |
