Metabolite Identification
Common Name1,2-Dehydrosalsolinol
Description1,2-dehydrosalsolinol(1-methyl-6,7-dihydroxy-3,4-dihydroisoquinolines) is formed through the decarboxylation of salsolinol-1-carboxylic acid (1-methyl-6,7-dihydroxy-1,2,3,4- tetrahydroisoquinoline-1-carboxylic acid), a novel endogenous catecholic adduct of dopamine and pyruvic acid, examined in nuclei-free homogenates of rat liver, whole brain, and kidney, as well as in buffer only. Liquid chromatographic analysis of incubations for varying times (30 min to 5 h) showed that the tetrahydroisoquinoline substrate decarboxylated oxidatively, forming the DSAL (PMID: 3369867 ). It is involved in Tyrosine Metabolism.
