常見(jiàn)問(wèn)題列表
黃酮木脂素類(lèi)化合物
水飛薊賓屬于黃酮木脂素類(lèi)化合物,從水飛薊Silybum marianum (L.)Gaertn.的種子中提取分離得到。水飛薊賓由2種非對(duì)映異構(gòu)體水飛薊賓A(2R,3R,10R,11R)和水飛薊賓B(2R,3R,10S,11S)等比例混合組成,具有多種生物活性,尤為突出的是保護(hù)肝臟和清除自由基的作用。性狀
類(lèi)白色結(jié)晶性粉末,無(wú)臭,味微苦澀。有引濕性,不溶于水,溶于丙酮,略溶于甲醇、乙醇,難溶于氯仿,易溶于稀堿溶液。其葡甲胺易溶于水。本品系從菊科水飛薊屬植物水飛薊果實(shí)中提取分離的一種黃酮類(lèi)化合物。藥動(dòng)學(xué)
口服吸收良好,達(dá)峰時(shí)間約1.5h,口服后48h排出量約為20%,其中80%以代謝物形式由膽汁排出,其余大部分以原形從尿中排出。藥理作用
水飛薊賓能夠穩(wěn)定肝細(xì)胞膜,保護(hù)肝細(xì)胞的酶系統(tǒng),清除肝細(xì)胞內(nèi)的活性氧自由基,從而提高肝臟的解毒能力,避免肝細(xì)胞長(zhǎng)期接觸毒物。 經(jīng)實(shí)驗(yàn)結(jié)果表明,對(duì)四氯化碳、毒蕈堿等肝臟毒物引起的各種類(lèi)型肝損傷具有不同程度的保護(hù)和治療作用,并對(duì)四氯化碳引起的丙氨酸氨基轉(zhuǎn)移酶的升高有一定的阻止作用。作用機(jī)制
水飛薊賓是一種來(lái)自于天然植物的類(lèi)黃酮物質(zhì),水飛薊賓被證明可以抑制細(xì)胞增殖和誘導(dǎo)細(xì)胞凋亡,同時(shí)具有抗血管生成的特性。腫瘤細(xì)胞凋亡的誘導(dǎo)是由內(nèi)質(zhì)網(wǎng)應(yīng)激介導(dǎo)的。水飛薊賓起著STAT3靶向抑制劑的作用以及抑制免疫檢查點(diǎn)PD-L1和EMT的調(diào)節(jié)作用,是一種有前途的NSCLC佐劑。也有文獻(xiàn)證明通過(guò)下調(diào)肌動(dòng)蛋白細(xì)胞骨架和PI3K / Akt分子通路抑制癌細(xì)胞。多項(xiàng)研究表明,水飛薊賓通過(guò)與腫瘤抑制基因p53相互作用發(fā)揮其保護(hù)作用。生物活性
Silybin 是一種從草薊 (Silybum marianum) 種子中分離出來(lái)的黃素寡糖。Silybin 誘導(dǎo)凋亡 (apoptosis),并具有保肝,抗氧化,抗炎,抗癌活性。體外研究
