3-Methyl-quinoxaline-2-carboxylic Acid Chemical Properties,Uses,Production
Description
3-Methylquinoxaline-2-carboxylic acid (MQCA) is a major metabolite of olaquindox, an antibiotic and swine growth regulator. It induces cell cycle arrest at the S phase and is toxic to Chang liver cells in a concentration- and time-dependent manner. MQCA has been used as a marker of olaquindox use in livestock applications.
Chemical Properties
