The study aimed to investigate potential mechanisms for the anti-hypertensive effects of RVPSL on spontaneously hypertensive rats (SHRs) using a non-targeted metabonomic approach. In this study, UPLC/MS-based non-targeted metabolomics was performed to discover metabolite variation of serum in SHRs with RVPSL treatment. As a result, the serum metabolites of SHRs that were administered RVPSL for four weeks exhibited distinct alterations. Nine potential biomarkers, , choline, adenosine, adrenic acid, L-tryptophan, niacinamide, glycocholic acid, propiolic acid, D-glyceraldehyde 3-phosphate, and phosphoglycolic acid, were significantly altered, which were mainly involved in lipid metabolism, vitamin and amino acid metabolism, purine metabolism, the MAPK signaling pathway, and the renin-angiotensin system. This study suggested that RVPSL potentially exerted potent effects of alleviating hypertension in the SHRs mainly integrated regulations of metabolism and production of choline, L-tryptophan, nicotinamide, and adenosine.
本研究旨在采用非靶向代谢组学方法探究 RVPSL 对自发性高血压大鼠（SHR）的降压作用机制。在本研究中，我们采用 UPLC/MS 非靶向代谢组学方法，发现 RVPSL 处理 SHR 后血清代谢物的变化。结果表明，给予 RVPSL 治疗 4 周的 SHR 血清代谢物发生明显改变。9 个潜在的生物标志物，包括胆碱、腺苷、花生四烯酸、二十二碳五烯酸、L-色氨酸、烟酰胺、甘胆酸、丙炔酸、D-甘油醛 3-磷酸和磷酸甘油酸，均发生显著改变，主要涉及脂类代谢、维生素和氨基酸代谢、嘌呤代谢、MAPK 信号通路和肾素-血管紧张素系统。本研究表明，RVPSL 可能通过调节代谢和胆碱、L-色氨酸、烟酰胺和腺苷的生成，发挥缓解 SHR 高血压的作用。
