    • PURPOSE: A sesquiterpene lactone compound, costunolide is provided, which inhibits production of nitric oxide(NO) or tumor necrosis factor-alpha(TNF-alpha)(they are important factor for controling of human immune system); and inhibits activity of NF-kappaB, the important transcription factor in representation of inflammation-mediate-factor; so which can be used as a medicine for inflammation-related disease and immune-disease. CONSTITUTION: The costunolide is gained from Magnolia grandiflora L. by methanol-extracting, which can be administrated by oral or parenteral, and can be used as a form of common pharmaceutical preparation, e.g., tablets, pills, granules, powders, capsules, suspension, liquid preparation for oral, emulsion, syrup, sterilized solution for injection, suppositories. An effective dosage of sesquiterpene lactone compound, the costunolide is 5-50mg/kg, desirably 5-20mg/kg, which can be administrated 1-3times per day.
    • 目的:提供倍半萜内酯化合物,其可以抑制一氧化氮(NO)或肿瘤坏死因子-α(TNF-α)的产生(它们是控制人体免疫系统的重要因素); 并抑制NF-κB的活性,NF-κB是代表炎症介导因子的重要转录因子; 因此可用作炎症相关疾病和免疫疾病的药物。 成分法:通过甲醇提取法,从大兰木兰获得木贼多糖,其可以通过口服或肠胃外给药,并且可以用作常见药物制剂的形式,例如片剂,丸剂,颗粒剂,粉剂,胶囊剂,悬浮液 口服液剂,乳剂,糖浆,注射用灭菌溶液,栓剂。 有效剂量的倍半萜内酯化合物,肋骨瓜内酯为5-50mg / kg,理想的为5-20mg / kg,可以每天施用1-3次。

    • PURPOSE: Pregnane glycoside of formula (1) and/or formula (2) which is isolated from Cynanchum wilfordii and its use as an anticancer agent are provided. CONSTITUTION: A pregnane glycoside represented by formula (1), isolated from Cynanchum wilfordii, is prepared by carrying out the following steps of: extracting the roots of Cynanchum wilfordii ground and drying in a shade with methanol and concentrating the extract under vacuum to obtain the methanol extract; fractionating to dichloromethane and water; performing a silica gel column chromatography and then obtaining an active fraction using n-hexane ethylacetate step gradient system; performing chromatography on a RPMPLC column to the active fraction; and recrystallizing with methanol. The compound increases the activities of the anticancer agent by preventing the anticancer agent from being released from a cell line having a multi-drug resistance, inhibits the replication of an endothelial cell necessary to the angiogenesis and inhibits cancer cellular infiltration by decreasing the activities of matrix metalloprotease and the expression of the gene encoding the enzyme.
    • 目的:提供从仙妮兰(Cynanchum wilfordii)中分离得到的式(1)和/或式(2)的芸香苷及其作为抗癌剂的用途。 构成:通过以下步骤制备由茜草(Cynanchum wilfordii)分离的由式(1)表示的孕烷苷,其中提取枸杞子的根,用甲醇在阴凉处干燥,并将提取物真空浓缩,得到 甲醇提取物; 分馏成二氯甲烷和水; 进行硅胶柱色谱,然后使用正己烷乙酸乙酯梯度系统获得活性级分; 在RPMPLC柱上进行色谱至活性级分; 并用甲醇重结晶。 该化合物通过防止抗癌剂从具有多重耐药性的细胞系中释放而增加抗癌剂的活性,抑制血管生成所必需的内皮细胞的复制,并通过降低基质的活性来抑制癌细胞浸润 金属蛋白酶和编码该酶的基因的表达。
