Pregnenolone monosulfate acts as a signaling-specific inhibitor of cannabinoid CB1 receptor, reduces several effects of tetrahydrocannabinol (THC). CB1 Human Endogenous Metabolite
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)[1].
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[1].

Animal experiment: |
Mice and Rats[1]Adult male Wistar rats (weighing 320-340g), Sprague Dawley male rats (weighing 330-350g), C57BL/6N mice (2-3 months) and CD1 mice (weighing 25-30 g at the beginning of the experiments) are used. Pregnenolone is injected subcutaneously (sc). The injection volumes are 1 mL/kg of body weight for rats and 10 mL/kg for mice[1]. |

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
