LIK-066 (licogliflozin) is an inhibitor of the sodium-dependent glucose co-transporter (sodium-glucose transporter; sodium-glucose transport protein; sodium-glucose linked transporter; SGLT) family members 1 and 2 (SGLT1/2) with antihyperglycemic activity. By binding to and blocking SGLT1/2, licogliflozin suppresses the reabsorption of glucose in the proximal tubule within the kidneys and enhances urinary excretion of glucose. This normalizes blood glucose levels. LIK-066 is in phase II clinical trials by Novartis for the treatment of type 2 diabetes. Licogliflozin treatment (1-84 days) leads to significant weight loss and favorable changes in a variety of metabolic parameters and incretin hormones. Dual inhibition of SGLT1/2 with licogliflozin in the gut and kidneys is an attractive strategy for treating obesity and diabetes.
