Capsaicin from chili ( Capsicum spp.) inhibits vascular smooth muscle cell proliferation

F1000Res. 2015 Jan 27:4:26. doi: 10.12688/f1000research.6007.1. eCollection 2015.


Accelerated vascular smooth muscle cell (VSMC) proliferation is implied in cardiovascular disease and significantly contributes to vessel lumen reduction following surgical interventions such as percutaneous transluminal coronary angioplasty or bypass surgery. Therefore, identification and characterization of compounds and mechanisms able to counteract VSMC proliferation is of potential therapeutic relevance. This work reveals the anti-proliferative effect of the natural product capsaicin from Capsicum spp. by quantification of metabolic activity and DNA synthesis in activated VSMC. The observed in vitro activity profile of capsaicin warrants further research on its mechanism of action and potential for therapeutic application.
