Pregnenolone monosulfate 3β-Hydroxy-5-pregnen-20-one monosulfate

产品介绍

Pregnenolone monosulfate (3β-Hydroxy-5-pregnen-20-one monosulfate) 是一种功能强大的神经甾体，是包括甾体酮在内的各种甾体激素的主要前体。Pregnenolone monosulfate 是大麻素 CB1 受体的信号传导特异性抑制剂，抑制由 CB1 受体介导的四氢大麻酚 (THC) 的作用。Pregnenolone monosulfate 可以保护大脑免受大麻中毒。Pregnenolone monosulfate 也是一种 TRPM3 通道激活剂，也可以弱激活 TRPM1 通道。

生物活性

Pregnenolone monosulfate (3β-Hydroxy-5-pregnen-20-one monosulfate) is a powerful neurosteroid, the main precursor of various steroid hormones including steroid ketones. Pregnenolone monosulfate acts as a signaling-specific inhibitor of cannabinoid CB1 receptor, inhibits the effects of tetrahydrocannabinol (THC) that are mediated by the CB1 receptors. Pregnenolone monosulfate can protect the brain from cannabis intoxication. Pregnenolone monosulfate is also a TRPM3 channel activator, and also can weakly activate TRPM1 channels.

体外研究

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).

体内研究

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.
