原人参二醇(Protopanaxadiol,PPD)是一种甾体化合物,分子式C
30H
52O
3,具有达玛烷骨架。是人参二醇型人参皂苷的骨架分子。[1][2]与原人参三醇的不同之处在于,它的6号位没有羟基。
原人参二醇对人体的影响尚不清楚。一项研究表明,它对内皮细胞有迅速的非基因性影响,与糖皮质激素受体及雌激素受体β结合。这项研究还显示,它能使细胞内钙离子浓度增加。[3]
上海中药创新研究中心的“优欣定”产品内为高纯度原人参二醇,号称是首个单分子抗抑郁中药。药物在2023年5月进入III期实验。[4]II期临床实验结果于2024年11月发布。[5][6]
上中创研的一篇论文描述了此药的口服剂量和IIa期志愿者血浆浓度的线性关系,但未给出半衰期、生物利用率等信息。[7]在大鼠中,本品口服生物利用率约48%,半衰期为6.25小时(作为原人参二、三醇均有的混合提取物喂食)。单独口服时,生物利用率降低到20.7–36.8%。[8]
