Myrtillin (Delphinidin 3-o-glucoside) is a kind of anthocyanin monomer, which is mainly distributed in various plants and can be analyzed qualitatively and quantitatively by high performance liquid chromatography (HPLC) Mass spectrometry (Mass) and nuclear magnetic resonance (NMR).
Myrtillin at 50 uM does not affect cell viability, also showing that delphinidin in association with lipopolysaccharide was able to induce MSC proliferation. Additionally, delphinidin modulated the MSC immune response, showing increased levels of anti-inflammatory cytokines such as IL-10 and TGF-β as well as lower expression of NFκB[2]. Myrtillin showed potential for binding with and inhibiting immune checkpoints, PD-1 and PD-L1, which can activate immune response in the tumor microenvironment and induce cancer cell death[3].
Myrtillin (20 mg/kg) decreased serum TG, TC, LDL-C, and HDL-C. Myrtillin (20 mg/kg) also reduced lipid levels in the liver and aorta. Myrtillin (20 mg/kg) down-regulated the mRNA levels of IL-6, VCAM-1, and NF-κB and up-regulated the mRNA levels of GSH-PX and SOD1.DP alleviated the HFD-induced oxidative stress and inflammation in atherosclerosis rabbits[1].

50 uM Myrtillin 不影响细胞活力，这也表明飞燕草素与脂多糖结合能够诱导 MSC 增殖。此外，飞燕草素调节 MSC 免疫反应，显示抗炎细胞因子水平升高，如 IL-10 和 TGF-β；以及 NFκB[2] 的较低表达。 Myrtillin 具有结合和抑制免疫检查点 PD-1 和 PD-L1 的潜力，可激活肿瘤微环境中的免疫反应并诱导癌细胞死亡[3]。
