개요
The Australian Therapeutic Goods Administration (TGA) and the European Commission approved dapagliflozin in October and November 2012, respectively, as an adjunct to diet and exercise for the treatment of type 2 diabetes. Dapagliflozin is a potentially attractive therapy due to its glucosesensitive and insulin-independent mechanism of action. It is a first-in-class selective SGLT2 inhibitor (IC₅₀=1.1 nM; selectivity vs. SGLT1 >1000) that lowers the renal threshold for reabsorption of glucose, allowing excess glucose to be eliminated via the kidneys. In normal rats, administration of dapagliflozin promotes dose-dependent excretion of up to 1900 mg of glucose over a 24 h period, with amaximal effect at 3 mg/kg. In a ratmodel of diabetes, pretreatment with the pancreatic toxin streptozotocin results in hyperglycemia that is reduced 55% by administration of a single 0.1 mg/kg dose of dapagliflozin compared with vehicle. Aryl O-glucoside SGLT2 inhibitors were early entrants into the clinic, but the aryl C-glucoside linkage found in dapagliflozin confers resistance to glucosidase-mediated metabolism leading to improved clinical utility relative to aryl O-glucosides. The modified carbohydrate–aglycone linkage required concomitant adjustment from an ortho- to a meta-substituted arylglucoside to achieve potent SGLT2 inhibition. Dapagliflozin was synthesized in several steps via reaction of an aryllithium with per-silylated gluconolactone to form the key C-glucoside linkage. An alpha-selective reduction of the resultant anomeric glycoside gave the desired beta-Carylglucoside. The main circulating (inactive) metabolite is the result of 3-O-glucuronidation of the glucosylmoiety. Of the minority metabolites, the main oxidative species result from O-dealkylation of the ethoxy-group and hydroxylation of the biarylmethane moiety.

정의
ChEBI: A C-glycosyl comprising beta-D-glucose in which the anomeric hydroxy group is replaced by a 4-chloro-3-(4-ethoxybenzyl)phenyl group. Used (in the formo f its propanediol monohydrate) to improve glycemic ontrol, along with diet and exercise, in adults with type 2 diabetes.
