常見(jiàn)問(wèn)題列表

生物活性
Pregnenolone monosulfate (3β-Hydroxy-5-pregnen-20-one monosulfate) 是一種功能強(qiáng)大的神經(jīng)甾體,是包括甾體酮在內(nèi)的各種甾體激素的主要前體。Pregnenolone monosulfate 是大麻素 CB1 受體的信號(hào)傳導(dǎo)特異性抑制劑,抑制由 CB1 受體介導(dǎo)的四氫大麻酚 (THC) 的作用。Pregnenolone monosulfate 可以保護(hù)大腦免受大麻中毒。
靶點(diǎn)

CB1

Human Endogenous Metabolite

體外研究

CB1 receptor stimulation increases brain Pregnenolone levels, which in turn exerts a negative feedback on the activity of the CB1 receptor antagonizing most of the known behavioral and somatic effects of THC. Pregnenolone likely acts as a signaling-specific negative allosteric modulator binding to a site distinct from that occupied by orthosteric ligands. Pregnenolone does not modify agonist binding but only agonist efficacy.
The effect of THC is significantly attenuated when slices are pre-treated with Pregnenolone 100 nM (15.1±1.8 % of inhibition). These effects are likely due to a pre-synaptic action of Pregnenolone. Thus, Pregnenolone blocks the increase in paired-pulse ratio (PPR) induced by THC but does not modify either the amplitude or the decay time of miniature EPSC (mEPSC).

體內(nèi)研究

Pregnenolone administration (2-6 mg/kg) blocks THC-induced food-intake in Wistar rats and in C57BL/6N mice, and blunts the memory impairment induced by THC in mice, but it does not modify these behaviors per se . Injections of Pregnenolone (2 and 4mg/kg) before each self-administration session reduce the intake of WIN 55,212-2 and reduce the break-point in a progressive ratio schedule.
