An insight to treat cardiovascular diseases through phytochemicals targeting PPAR-α

Peroxisome proliferator-activated receptor-alpha (PPAR- alpha) belonging to the nuclear hormone receptor superfamily is a promising target for CVDs which mechanistically improves the production of high-density lipid as well as inhibit vascular smooth muscle cell proliferation. PPAR-a mainly interferes with adenosine monophosphate- activated protein kinase, transforming growth factor-beta-activated kinase, and nuclear factor-kappa B pathways to protect against cardiac complications. Natural products/ extracts could serve as a potential therapeutic strategy in CVDs for targeting PPAR-alpha with broad safety margins. In recent years, the understanding of naturally derived PPAR-alpha agonists has considerably improved; however, the information is scattered. In vitro and in vivo studies on acacetin, apigenin, arjunolic acid, astaxanthin, berberine, resveratrol, vaticanol C, hispidulin, ginsenoside Rb3, and genistein showed significant effects in CVDs complications by targeting PPAR-alpha. With the aim of demonstrating the tremendous chemical variety of natural products targeting PPAR-alpha in CVDs, this review provides insight into various natural products that can work to prevent CVDs by targeting the PPAR-alpha receptor along with their detailed mechanism.
