摘要
Ocotillol型皂苷是一类侧链上含有四氢呋喃环的四环三萜类皂苷,主要存在于人参属植物中,并具有抗炎、抗菌、拮抗吗啡依赖、预防老年痴呆、保护心脑血管及神经系统等功效.天然存在的ocotillol型皂苷较少,近年来,已有较多20(S)-ocotillol型皂苷的半合成、以X射线衍射确证绝对构型、抗心肌缺血和代谢等研究报道,其中差向异构体的抗心肌缺血活性与代谢呈现立体选择性.综述了ocotillol型皂苷的分离、合成、绝对构型确证、药理活性、代谢等方面的研究进展.
Ocotillol-type saponins are a kind of tetracyclic triterpenoid ginsenoside with a tetrahydrofuran ring in the side chain. Ocotillol-type saponins mainly exist in panax plants and possess anti-inflammatory, antibacterial, morphine-antagonistic, neuroprotective, cardioprotective effects, etc. There are less ocotillol-type saponins in natural plants. Recently, many studies on the semi-synthesis, absolute configuration confirmation using X-ray diffraction, effect of anti-myocardial ischemic and metabolism of 20（S）-ocotillol-type saponins have been reported. It was found that 24R-epimer and 24S-epimer had stereoselectivity in anti-ischemic effect and pharmacokinetics. In this paper, the advances of the separation, synthesis, absolute configuration confirmation, pharmacological activity, metabolism of ocotillol-type saponins are reviewed.
