[体外研究]

野百合碱(MCT)是一种11元大环吡咯里西啶生物碱(PA),来源于猪屎豆(Crotalaria spectabilis)植物的种子[1]。野甘露碱是一种天然配体,具有剂量依赖性细胞毒性,具有强大的抗肿瘤活性。野百合碱的体外细胞毒性证实为IC50为24.966μg/ mL,2 X IC50对HepG2细胞的遗传毒性[2]。

[体内研究]

MCT引起大鼠肺血管综合征,其特征为增殖性肺血管炎,肺动脉高压(PH)和肺心病[3]。在肺动脉高压(PAH)的临床前模型中,野百合碱动物模型提供了模拟人PAH几个关键方面的优势,包括血管重塑,平滑肌细胞增殖,内皮功能障碍,炎性细胞因子上调和右心室衰竭,需要单次注射药物[4]。通过注射野百合碱观察到与PH发展相关的多种途径的变化,包括活化的糖酵解,增加的增殖标记,肉毒碱稳态的破坏,炎症和纤维化生物标志物的增加以及谷胱甘肽生物合成的减少[5]。

[动物实验]

大鼠：在该研究中使用总共20只雄性Sprague Dawley大鼠（SD; 220-270g）（每组n = 10）。对照组接受野百合碱（MCT）的载体。肺动脉高压前期（PH）组单次注射MCT（60 mg / kg ip）诱导并在14天后处死[5]。
