The Constituents of Schizandra chinensis Baill. X. The Structures of .GAMMA.-schizandrin and four new lignans,(-)-gomisins L1 and L2,(.+-.)-gomisin M1 and (+)-gomisin M2.
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.
从五味子果实中分离出四种新的二苯并环辛二烯木脂素,分别命名为(-)-大黄素 L1 (6)和 L3 (7)、(±)-大黄素 M1 (8)和(+)-大黄素 M2 (9)。(五味子科)果实中分离得到。通过化学和光谱研究阐明了它们的绝对结构。Kochetkov 等人和 Liu 等人也根据化学和光谱研究阐明了 γ-五味子素(1,dl-form)的立体结构,其平面结构已被 Kochetkov 等人和 Liu 等人提出。

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.

structure-activity relationships of lignans from Schisandra chinensis and their derivatives as plateletactivatingfactor (PAF) antagonists. Strong activity was shown in lignans without an ester group at C-6, a hydroxyl group at C-7 or a methylene dioxy moiety and with an R-biphenyl configuration. 6(7)-Dehydroschisandrol A, a derivative of schisandrol A, showed the highest activity (IC50, 2.1x10(-6) M) in this
