Sodium propionate-d5 is the deuterium labeled Propionate sodium (HY-B1773A). Sodium propionate is an orally active short-chain fatty acid. Sodium propionate can be produced by intestinal bacteria from the metabolism of dietary fiber. Sodium propionate increases PPAR-gamma, inhibits NF-kappaB activation, and reduces COX-2 expression and NO production. Sodium propionate also induces Apoptosis and Autophagy. Sodium propionate reduces HSV-1-induced keratitis. Sodium propionate has anticancer effects against glioblastoma. Sodium propionate exhibits neuroprotective, antioxidant, and anti-inflammatory activities. Sodium propionate can be used in the research of spinal cord injury and Alzheimers disease[1][2][3][4][5][6].
