Abstract

Background: Danshensu (3-(3,4-dihydroxyphenyl) lactic acid, DSS) is one of the most promising cardioprotective components in the root of Salvia miltiorrhiza but its poor chemical stability poses hurdles in its therapeutic development. It is therefore desirable to enhance the stability of DSS by chemical modification to improve its activities. In the present study, a novel DSS derivative named ADTM was synthesized and characterized for its cardioprotective properties. Methods: Oxidative stress was induced in H9c2 cardiomyoblast cells by tert-butylhydroperoxide (t-BHP) and the protective effects of ADTM were evaluated. For in vivo study, adult rats were treated with vehicle, DSS, ADTM or amlodipine (n=6-8/group) for 24 h before the induction of acute myocardial ischemia. At the end of each experiment, infarct sizewas measured. Underlying themechanisms of the cardioprotective effects of ADTMwere further investigated in H9c2 cells and rat myocardium by evaluating the effects of Nrf2 (NF-E2-related factor 2) and Akt/ PI3K pathways. Results: ADTMwas approximately 10 times more effective than DSS against t-BHP-induced cell injury in H9c2 cells. In rat myocardial ischemia model, ADTM treatment significantly alleviated myocardial infarction. Akt/PI3K and Nrf2 pathways were demonstrated to be involved in both in vitro and in vivo experiments. Conclusions: These results demonstrated that ADTM displayed much better cardioprotective effects than its parent compounds both in vitro and in vivo. This cardioprotection is mediated, at least in part, through Akt/PI3K and Nrf2 pathways. This novel compound represents a promising candidate for the treatment of cardiovascular diseases (CVDs), particularly myocardial infarction.
