Exploring the Protective Effects of Taxifolin in Cardiovascular Health: A Comprehensive Review

Abstract

Taxifolin is a natural flavonoid found in a variety of plants, including Siberian larch (Larix sibirica) and milk thistle (Silybum marianum), that has attracted attention for its multifaceted pharmacological properties, including cardioprotective effects. Through its antioxidant and anti-inflammatory activities, taxifolin has shown significant therapeutic potential in cardiovascular diseases such as atherosclerosis, myocardial ischemia, and diabetic cardiomyopathy. This review highlights the cardioprotective effects of taxifolin in preclinical models of atherosclerosis, ischemia/reperfusion injury, and diabetic cardiomyopathy. Taxifolin contributes to its cardioprotective effects through key mechanisms such as modulation of pathways such as PI3K/AKT and JAK2/STAT3, inhibition of NADPH oxidase, and modulation of nitric oxide production. Recent studies have shown that taxifolin can affect glucose metabolism by modulating sodium–glucose transporter (SGLT) expression, potentially enhancing the cardioprotective effects of SGLT2 inhibitors. Given the emerging role of SGLT2 inhibitors in the management of cardiovascular disease, further investigation of the interaction of this pathway with taxifolin may provide new therapeutic insights. Although taxifolin has multifaceted potential in the prevention and treatment of cardiovascular disease, further studies are needed to better understand its mechanisms and validate its efficacy in different disease stages. This review aims to provide a rationale for the clinical application of taxifolin-based cardiovascular therapies and suggest directions for future research.
