制备方法与用途

概述

轮环藤所含生物碱的结构类型为较为独特的头尾连接的BBI。鉴于这类生物碱良好的药理作用,研究人员较系统地分离和研究了采自四川邻水华蓥山地区的轮环藤的生物碱成分。从轮环藤根中成功分离到了8个生物碱成分:异粒枝碱(Ⅰ)、轮环藤碱(Ⅱ)、海岛轮环藤碱(Ⅲ)、海岛轮环藤酚碱(Ⅳ)、racemosinine B(Ⅴ)、木兰碱(Ⅵ)、α-cyclanoline(Ⅶ)和steponine(Ⅷ)。

作用

三种BBI(左旋箭毒碱、轮环藤碱、异粒枝碱),可以通过抑制过度活化的巨噬细胞内iNOS的表达来抑制LPS诱导的巨噬细胞NO释放,同时还可以抑制活化的巨噬细胞释放炎症因子IL-1β、TNF-α和IL-6。值得注意的是,这些BBI并不会影响细胞的存活率。

制备

取轮环藤根粗粉10.5kg,采用95%乙醇进行三次浸提(8倍量)。将得到的乙醇液浓缩后加入1L水中,并用2mol·L-1盐酸调pH值至3。此时,酸水层通过乙酸乙酯萃取两次(每次2L),随后进一步使用氨水调节pH值至10并进行氯仿萃取浓缩,最终得到总碱A(48g)和总碱B(11g)。48g的总生物碱A以氯仿溶解后,通过硅胶柱层析、氯仿-甲醇梯度洗脱,并分段收集四个部分。从F2中经过多次硅胶柱层析得到单体化合物Ⅰ(2.9g)、轮环藤碱(19mg)、Ⅲ(400mg)和Ⅳ(120mg)。而3.3g的F3通过硅胶柱层析得化合物Ⅴ(16mg)。对于总生物碱B,采用甲醇溶解后经多次硅胶柱层析获得单体化合物Ⅵ(1.1g)、Ⅶ(50mg)和Ⅷ(36mg)。

化学性质

轮环藤碱为白色结晶粉末状物质,可以溶于甲醇、乙醇、DMSO等有机溶剂。其来源包括白药子、地不容、光叶地不容、南轮环藤、四川轮环藤、瓦氏独活和锡生藤。

用途

轮环藤碱具有抗肿瘤、抗感染及抗寄生虫病的作用。

  • 8-ARM POLYETHYLENE GLYCOL DERIVATIVE, MANUFACTURING METHOD AND MODIFIED BIO-RELATED SUBSTANCE THEREBY
    申请人:Xiamen Sinopeg Biotech Co., Ltd.
    公开号:EP3315531A1
    公开(公告)日:2018-05-02
    Disclosed are an 8-arm polyethylene glycol (PEG) derivative (formula 1), manufacturing method and modified bio-related substance thereby, wherein a tetravalent group U and four trivalent groups Ec form a highly symmetric octavalent central structure CORE0 together, Lc connects the octavalent center to eight PEG arms having polydiversity or monodiversity and having n1-n8 as the degrees of polymerization thereof. The terminal of one PEG chain is connected to at least one functional group F (k ≥ 1), and said PEG chain and F can be directly connected (g = 0) or connected with a divalent linking group L0 connected with a terminal branched group G (g = 1) therebetween. The latter provides more reacting sites to combine more pharmaceutical molecules, thereby increasing the drug loading capacity. The near-center symmetric structure of the derivative allows more precise control over the molecular weight during large-scale production, thereby facilitating acquisition of a product having a narrower molecular weight distribution. A bio-related substance modified thereby has a more uniform and controllable performance.
    本发明公开了一种 8 臂聚乙二醇(PEG)衍生物(式 1)、其制造方法和改性生物相关物质,其中一个四价基团 U 和四个三价基团 Ec 共同形成一个高度对称的八价中心结构 CORE0,Lc 将八价中心连接到八个 PEG 臂上,这些 PEG 臂具有多元性或单元性,其聚合度为 n1-n8。一条 PEG 链的末端与至少一个官能团 F(k ≥ 1)相连,所述 PEG 链和 F 可以直接相连(g = 0),也可以通过二价连接基 L0 与中间的末端支化基 G(g = 1)相连。后者提供了更多的反应位点,可以结合更多的药物分子,从而提高药物负载能力。衍生物的近中心对称结构可以在大规模生产过程中更精确地控制分子量,从而有利于获得分子量分布更窄的产品。由此改性的生物相关物质具有更均匀、更可控的性能。
