OBJECTIVE Only limited number of drugs are currently available for treating ischemic stroke. Therapeu?tic angiogenesis has recently emerged as one of the most promising therapies for cerebral ischemic injury. Isopropyl-β-(3,4-dihydroxyphenyl)-α-hydroxypropanoate (IDHP) is a metabolite derived from the botanical formulation for Dantonic?. Here, we investigated the angiogenic efficacy of IDHP in cerebral ischemia. METHODS The in vivo effects of IDHP were evaluated in the C57BL/6 mouse Matrigel plug and rat transient middle cerebral artery occlusion (tMCAO) models. Primary human umbilical vein endothelial cells (HUVEC) and human brain microvascular endothelial cells (HBMEC) were used to explore the effects of IDHP on stimulating proliferation, migration and tube formation in vitro. ELISA and Western blotting were used to quantitate the release and expression of relevant target molecules and signaling path?ways. RESULTS IDHP reduced infarct volume and improved sensorimotor function in rats subjected to tMCAO
