概述
丹参,为唇形科植物丹参(SalviamiltiorrhizaBunge)的干燥根及根茎,最早记载于《神农本草经》。丹参味苦、性微寒,有活血祛瘀、安神宁心之传统功效。植物化学研究显示,丹参的化学成分主要包括脂溶性和水溶性两部分。丹参酮类是丹参中的主要脂溶性成分,是具有橙黄色或橙红色特征的松香烷型二萜类化合物。药理研究证明,丹参酮类化合物具有抗氧化、抗菌及抗肿瘤方面的作用。二氢丹参酮I(DihydrotanshinoneI,简称DHT)是丹参酮大家族的一员,其分子式为C18H14O3,分子量为278.3。研究显示,DHT具有抗肿瘤、心血管保护的药理活性。
应用
二氢丹参酮I是丹参根茎的提取物,丹参是临床中最常用的活血化瘀的中药,相关文献报道丹参具有增加冠脉血流量、扩张冠状动脉、防止心肌缺血等心血管作用,以及用于治疗胃癌癌、肝癌、宫颈癌等多种疾病。实验显示二氢丹参酮I(DHT)能有效改善实验性溃疡性结肠炎小鼠的包括体重下降、腹泻、血便和精神状态等多方面的一般状态,明显改善病理变化、显著减轻炎症反应、降低血浆炎症因子的水平等,显示出DHT具有明显的抗溃疡性结肠炎作用。二氢丹参酮I治疗溃疡性结肠炎的优点在于作用迅速、疗效确切且药效良好。此外,二氢丹参酮I为丹参中提取的天然成分,在实验过程中未见明显副作用及毒性反应,揭示了二氢丹参酮I是一种安全有效的抗溃疡性结肠炎的药物。
生物活性
Dihydrotanshinone I 是从丹参中分离到的天然产物,广泛用于心血管疾病的研究。Dihydrotanshinone I 可抑制 MERS-CoV。
体外研究
In lipopolysaccharide (LPS)-stimulated human umbilical vein endothelial cells (HUVECs), DHT (10 nM) decreases lectin-like ox-LDL receptor-1 (LOX-1) and NADPH oxidase 4 (NOX4) expression, reactive oxygen species (ROS) production, NF-κB nuclear translocation, ox-LDL endocytosis and monocytes adhesion. Dihydrotanshinone I induces caspase dependent apoptosis induced in HCT116 cells. Dihydrotanshinone I induces concentration and ROS dependent caspase activation. Apoptosis induced by Dihydrotanshinone I is completely prevented by Z-VAD-fmk. Apoptosis induced by Dihydrotanshinone I is significantly inhibited by pretreatment of Z-LEHD-fmk but only is partially inhibited by Z-IETD-fmk. Apoptosis induced by Dihydrotanshinone I is significantly increased by caspase-2 knockdown.
体内研究
DHT (10 and 25 mg/kg) significantly attenuates atherosclerotic plaque formation, alteres serum lipid profile, decreases oxidative stress and shrinks necrotic core areas in ApoE -/- mice. DHT dramatically inhibits the enhanced expression of LOX-1, NOX4, and NF-κB in aorta. Dihydrotanshinone I (1, 2, 4 mg/kg) treatment can improve cardiac function, reduce infarct size, ameliorate the variations in myocardial zymogram and histopathological disorders, decrease 20-HETE generation, and regulate apoptosis-related protein in myocardial ischemia-reperfusion rats.
