  五味子的木脂素作为血小板活化因子拮抗剂的构效关系。

  摘要：

  我们研究了五味子的木脂素及其衍生物作为血小板活化因子（PAF）拮抗剂的构效关系。在木脂素中显示出强活性，其在C-6处没有酯基，在C-7处没有羟基或亚甲基二氧基部分并且具有R-联苯基构型。五倍子A的衍生物6（7）-脱氢五倍子A表现出最高的活性（IC50，2.1x10（-6）M）。

  Four new dibenzocyclooctadiene lignans, named (-)-gomisins L1 (6) and L3 (7), (±)-gomisin M1 (8) and (+)-gomisin M2 (9), were isolated from the fruits of Schizandra chinensis BAILL. (Schizandraceae). Their absolute structures were elucidated by means of chemical and spectral studies. The stereostructure of γ-schizandrin (1, dl-form), the plane structure of which had already been suggested by Kochetkov et al. and Liu et al., was also elucidated on the basis of chemical and spectral studies.

  Methods of application of a class of compounds with a pharmacophore of dibenzocyclooctadiene in the preparation of anticancer medications, and particularly for the preparation of medications for the treatment of P-glycoprotein-mediated multidrug resistant (MDR) cancer and non-P-glycoprotein-mediated MDR cancer, such as multidrug resistant associated protein MRP1-mediated cancer. Methods of increasing the efficacy of anticancer agents are further disclosed. The class of compounds are of a potency to effectively reverse MDR cancer by inhibiting the drug transport activity of an ABC drug transporter, increase the intracellular accumulation of an anticancer agent in MDR cancer cells, enhance apoptosis of cancer cells induced by an anticancer agent, and directly kill cancer cells. The aforementioned methods of application of the present disclosure provide much potential for the treatment of cancer. Mass production of medications incorporating these chemical compounds will treat a significant number of patients affected by the condition of MDR cancer.
