(Leonurine) has attracted great attention due to its cardioprotective effects in myocardial infarction (MI). However, no systematic modifications and structure-activity relationship (SAR) studies could be traced so far. In this study, 35 analogs of SCM-198 were designed, synthesized and their cardioprotective effects were evaluated. The cell viability assay on cardiomyocyte cell line H9c2 challenged with H2O2
SCM-198(Leonurine)由于其对心肌梗死(MI)的心脏保护作用而引起了极大的关注。但是,到目前为止,尚无系统的修改和结构-活性关系(SAR)研究。在这项研究中,设计,合成了35种SCM-198类似物,并评估了它们的心脏保护作用。上的心肌细胞的细胞系的H9c2细胞生存力测定用H挑战2 ö 2表明几个类似物表现出比更有效的细胞保护作用SCM-198在1 μ M和10 μ M之间的浓度。在用1处理的细胞的LDH释放水平 μ中号140是可比较与细胞与10处理 μM SCM-198。因此,Bcl-2表达和caspase-3活化的结果表明14o的保护活性高于SCM-198。而且,在MI小鼠模型中,用14o预处理的小鼠的梗死面积比SCM-198小得多。机制研究表明14o改善了心脏形态,并减少了梗死边缘区域心肌细胞的凋亡,这已通过H&E和TUNEL染色证明。
