Sotagliflozin is an orally-delivered small molecule compound that we and Sanofi are developing for the treatment of type 1 and type 2 diabetes mellitus. Sotagliflozin was discovered by our scientists and inhibits both sodium-glucose cotransporter type 2, or SGLT2, a transporter responsible for most of the glucose reabsorption performed by the kidney, and sodium-glucose cotransporter type 1, or SGLT1, a transporter responsible for glucose and galactose absorption in the gastrointestinal tract. Our scientists discovered that mice lacking SGLT1, SGLT2 or both exhibit potent anti-diabetic phenotypes across multiple measures of glucose control and metabolism, and found that compounds inhibiting both targets had a favorable preclinical profile relative to compounds selective for SGLT2.
|This figure depicts a nephron, the basic functional unit of the kidney. The glucose reabsorption transporter, SGLT2, is expressed in the first segment of the proximal convoluted tubule (PCT S1) and is responsible for most of the glucose reabsorption that happens in the kidney where SGLT1 has a lesser role. Abbreviations: PCT S1 and S2, proximal convoluted tubule segments 1 and 2; PST S3, proximal straight tubule segment 3.|
|SGLT1 is the primary transporter for absorption of glucose and galactose in the gastrointestinal tract.|
