Rosolic Acid is an activator of Nrf2, as well as its downstream targets. Rosolic Acid increases the levels of angiogenic factors, decreases inflammation (TNF-α and IL-1β) and apoptotic markers (CXCL10 and CCL2). Rosolic Acid restores the function of pancreatic cells and protects endothelial cells (ECs) from endoplasmic reticulum stressed[1].
