常見問題列表
生物活性
Etiocholanolone (5β-Androsterone) 是睪酮的排泄代謝物，具有抗驚厥活性。相對(duì)于其對(duì)映體形式，Etiocholanolone 是一種較弱的神經(jīng)甾醇類?GABAA?receptor 正向變構(gòu)調(diào)節(jié)劑。體外研究
Etiocholanolone (10 μM) coapplication with GABA leads to an increase in the relative frequency of long openings (fraction of OT3, site A2 effect), but it is ineffective at increasing the duration of long openings (site B effect) or at decreasing the relative frequency of the activation-related closed time component (site A1 effect).
體內(nèi)研究
Etiocholanolone (intraperitoneal injection; 0-109.1 mg/kg; single dose) exhibits ED50?values of 57.6 and 109.1 mg/kg in the 6-Hz and PTZ tests, respectively. Protective activity in the 6-Hz test of 5β,3α-A persists for 2 h and is shorter than ent-5β,3α-A treatment (3 hours) in mice.
