制备方法与用途

概述

8-异戊烯基柚皮素(8-Prenylnaringenin,简称8PN)是啤酒花中发现的一种具有雌激素作用的异戊烯基黄酮。文献报道8PN是迄今为止发现的最具潜力的植物雌性激素之一。体内外研究表明,8PN在低剂量下就能发挥较强的雌激素作用,其效果甚至优于大豆异黄酮、金雀异黄素等其他已知植物雌激素,可以有效减缓妇女绝经期的各种症状,并且副作用较小,被认为是一种新型的潜在替代激素代替治疗法(Hormone Replacement Therapy, HRT)。

作用

除了上述功效外,8-异戊烯基柚皮素还具有预防癌症、防止骨质疏松、抑制血管增生及抗氧化等多种其他生物活性。

制备方法

一种微生物细胞催化异黄腐酚合成8-异戊烯基柚皮素的方法如下:

  1. 向培养液中接入爪哇正青霉(Eupenicillium javanicum)CGMCC NO.3.5706,得到预反应体系。
  2. 向步骤1所得的预反应体系中加入异黄腐酚溶液,在25-30℃条件下(优选28℃),进行转化反应5-7天(优选6天)。在此过程中,异黄腐酚用量为每升培养液0.01-0.1g(优选0.02g)。
  3. 将转化后的培养液经过后处理得到8-异戊烯基柚皮素。
生物活性

8-prenylnaringenin 是从啤酒花(Humulus lupulus)中分离出的一种异戊烯类黄酮,具有细胞毒性。它能通过诱导内源性、外源性通路介导的凋亡作用对HCT-116结肠癌细胞产生抗增殖活性,并通过激活小鼠Akt磷酸化途径,促进其从静止诱导的停用性肌肉萎缩中恢复。

化学性质

8-prenylnaringenin 为白色结晶粉末状物质,可溶于甲醇、乙醇、DMSO等有机溶剂,来源于啤酒花Humulus lupulus。

    8-Dimethylallylnaringenin 2′-hydroxylase, the crucial cytochrome P450 mono-oxygenase for lavandulylated flavanone formation in Sophora flavescens cultured cells
    摘要:
    8-Dimethylallylnaringenin (8-DMAN) 2'-hydroxylase, which is indispensable for the formation of a lavandulylated flavanone, sophoraflavanone G, was detected in cell suspension cultures of Sophora flavescens. The enzyme catalyzes the 2'-hydroxylation of 8-DMAN to leachianone G, and is tightly bound to the membrane. It required NADPH and molecular oxygen as cofactors, and was inhibited by several cytochrome P450 inhibitors such as carbon monoxide and cytochrome c, indicating that the reaction is mediated by a cytochrome P450 monooxygenase. The optimum pH of 8-DMAN 2'-hydroxylase was 8.5, and the enzyme hydroxylated only 8-DMAN. Apparent Km values for 8-DMAN and NADPH of the enzyme were 55 and 34 muM, respectively.

    An Efficient Method for C8-Prenylation of Flavonols and Flavanones
    摘要:
    Synthesis of C8-prenylated flavonols and flavanones via the palladium-catalyzed 7-O-1,1-dimethylprop-2-enylation, followed by Claisen rearrangement is described. Two regioselectivities (carbon-carbon bond formation at either the tail or head of the prenyl group and carbon-carbon bond formation at either C8 or C6) were efficiently improved when acetic anhydride was used as a solvent instead of N,N-dimethylformamide.

The reaction catalyzed by prenyltransferases represents a Friedel–Crafts alkylation of the flavonoid skeleton in the biosynthesis of natural prenylflavonoids and often contributes to the structural diversity and biological activity of these compounds. However, only a few plant flavonoid prenyltransferases have been identified thus far, and these prenyltransferases exhibit strict substrate

    use of expensive chemicals, or an elaborate synthesis. An easy synthesis strategy is the demethylation of xanthohumol, which is available due to hop extraction industry, using lithium chloride and dimethylformamide, but byproducts and low yield did not make this feasible until now. In this study, the demethylation of xanthohumol to 8-prenylnaringenin and 6-prenylnaringenin is described the first time

  • In Vitro Effect of 8-Prenylnaringenin and Naringenin on Fibroblasts and Glioblastoma Cells-Cellular Accumulation and Cytotoxicity
    作者:Monika Stompor、Łukasz Uram、Rafał Podgórski
    DOI:10.3390/molecules22071092

    Gliomas are one of the most aggressive and treatment-resistant types of human brain cancer. Identification and evaluation of anticancer properties of compounds found in plants, such as naringenin (N) and 8-prenylnaringenin (8PN), are among the most promising applications in glioma therapy. The prenyl group seems to be crucial to the anticancer activity of flavones, since it may lead to enhanced cell membrane targeting and thus increased intracellular activity. It should be noted that 8PN content in hop cones is 10 to 100 times lower compared to other flavonoids, such as xanthohumol. In the study presented, we used a simple method for the synthesis of 8PN from isoxanthohumol—O-demethylation, with a high yield of 97%. Cellular accumulation and cytotoxicity of naringenin and 8-prenylnaringenin in normal (BJ) and cancer cells (U-118 MG) was also examined. Obtained data indicated that 8-prenylnaringenin exhibited higher cytotoxicity against used cell lines than naringenin, and the effect of both flavones was stronger in U-118 MG cells than in normal fibroblasts. The anticancer properties of 8PN correlated with its significantly greater (37%) accumulation in glioblastoma cells than in normal fibroblasts. Additionally, naringenin demonstrated higher selectivity for glioblastoma cells, as it was over six times more toxic for cancer than normal cells. Our results provide evidence that examined prenylated and non-prenylated flavanones have different biological activities against normal and cancer cell lines, and this property may be useful in designing new anticancer drugs for glioblastoma therapy.
    神经胶质瘤是人类脑癌中最具侵袭性和最难治疗的类型之一。植物中发现的化合物(例如柚皮素 (N) 和 8-异戊二烯柚皮素 (8PN))的抗癌特性的鉴定和评估是神经胶质瘤治疗中最有前途的应用之一。异戊二烯基团似乎对于黄酮的抗癌活性至关重要,因为它可能导致增强的细胞膜靶向性,从而增加细胞内活性。值得注意的是,啤酒花球果中的 8PN 含量比其他类黄酮(例如黄腐酚)低 10 至 100 倍。在本研究中,我们采用了一种简单的方法从异黄腐酚-O-去甲基化合成8PN,收率高达97%。还检查了正常细胞 (BJ) 和癌细胞 (U-118 MG) 中柚皮素和 8-异戊二烯柚皮素的细胞积累和细胞毒性。获得的数据表明,8-异戊二烯柚皮素对使用的细胞系表现出比柚皮素更高的细胞毒性,并且两种黄酮在 U-118 MG 细胞中的作用比在正常成纤维细胞中更强。 8PN 的抗癌特性与其在胶质母细胞瘤细胞中的积累量(37%)显着高于在正常成纤维细胞中的积累量相关。此外,柚皮素对胶质母细胞瘤细胞具有更高的选择性,因为它对癌症的毒性比正常细胞高六倍多。我们的结果提供了证据,证明异戊二烯化和非异戊二烯化黄烷酮对正常细胞系和癌细胞系具有不同的生物活性,这种特性可能有助于设计用于治疗胶质母细胞瘤的新抗癌药物。
