Abstract:
Studies have shown that a variety of diseases such as cardiovascular disease, renal disease and cancer are closely related to trimethylamine oxide (TMAO). Clinically, abnormal elevation of TMAO has been used as an evaluation index of atherosclerosis (AS) prior to imaging. In this study, we investigated the effects of lipid metabolism disorders as well as pharmacological interventions on urinary TMAO using a hyperlipidemic golden gopher model. The study used 48 Syrian golden hamster modeled with a high-fat diet for 2 weeks, and then ezetimibe, simvastatin, ezetimibe and simvastatin groups were administered for 4 consecutive weeks, as well as the clinical trial drug, IMM-H007, for pharmacological intervention. The animal experiment was conducted in accordance with the regulations of the Ethics Committee for Experimental Animal Management and Animal Welfare of Institute of Materia Medica, Chinese Academy of Medical Sciences (approval number: SCXK (Beijing) 2021-0011). Urine from rats was analyzed for 2D band selective heteronuclear single quantum coherence (2D bs-HSQC) at week 2 and 4 after drug administration. The results indicated that, in comparison to the control group, the high-fat diet significantly elevated urinary TMAO levels in the model group of hamsters after both 2 and 4 weeks of treatment (P < 0.05). Urinary TMAO levels were significantly reduced (P < 0.05) in the model group after 2 or 4 weeks of intervention with ezetimibe, simvastatin, combination therapy, and IMM-H007, showing a marked decrease even after 2 weeks of treatment. The detection of TMAO could precede the measurement of serum biochemical indicators, facilitating earlier efficacy assessment. This study evaluated the modulatory effects of clinical drugs and clinical trial drugs on TMAO, which provides useful information for clinical drug use and drug research. It also provides a means of TMAO detection based on 2D NMR technology, which is helpful for the clinical application of TMAO detection index.
