Snake Venom Components: Tools and Cures to Target Cardiovascular Diseases Jacinthe Frangieh et al.

Abstract Cardiovascular diseases (CVDs) are considered as a major cause of death worldwide. Therefore, identifying and developing therapeutic strategies to treat and reduce the prevalence of CVDs is a major medical challenge. Several drugs used for the treatment of CVDs, such as captopril, emerged from natural products, namely snake venoms. These venoms are complex mixtures of bioactive molecules, which, among other physiological networks, target the cardiovascular system, leading to them being considered in the development and design of new drugs. In this review, we describe some snake venom molecules targeting the cardiovascular system such as phospholipase A2 (PLA2), natriuretic peptides (NPs), bradykinin-potentiating peptides (BPPs), cysteine-rich secretory proteins (CRISPs), disintegrins, fibrinolytic enzymes, and three-finger toxins (3FTXs). In addition, their molecular targets, and mechanisms of action-vasorelaxation, inhibition of platelet aggregation, cardioprotective activities-are discussed. The dissection of their biological effects at the molecular scale give insights for the development of future snake venom-derived drugs. Keywords: anti-platelet agent; cardiovascular diseases; drugs discovery; hypotensive agent; snake venom; vasorelaxant effect.
