Cardiovascular Effects of Ruthenium Complexes: A Potential Therapeutic Tool in Hypertension and Myocardial Injury.

Ruthenium complexes stand out as an excellent alternative in the field of organometallic chemistry with applications in various areas. Recently, in cardiovascular pharmacology, there has been a growing interest in investigating complexes that modulate the Nitric Oxide (NO) pathway without necessarily and directly donating NO. NO has a proven vasodilatory and cardioprotective effect, and it is known that reduced levels are associated with an increased risk of CardioVascular Diseases (CVD). Studies suggest that ruthenium complexes significantly contribute to the treatment of CVD pathophysiology through different pharmacological mechanisms, including the precise delivery of carbon monoxide (CO) to the molecular target, the release of nitric oxide species under visible and invisible (UV) light, the ability to stimulate the activation of soluble Guanylate Cyclase (sGC) enzyme, participation in the opening of potassium channels, and reduction of cytoplasmic calcium levels. This study aims to conduct a narrative review of the cardiovascular effects of ruthenium complexes, focusing on hypertension and myocardial injury, and demonstrate that metal complexes acting on the NO pathway may have promising targets for the development of therapeutic strategies in CVD treatment.
