Abstract

The present invention relates to chemical compounds that selectively inhibit glucose transporter 1 (GLUT1), to methods of preparing said compounds, to pharmaceutical compositions and combinations comprising said compounds, to the use of said compounds for manufacturing a pharmaceutical composition for the treatment or prophylaxis of a disease, as well as to intermediate compounds useful in the preparation of said compounds.

Description

[0001] The present invention relates to compounds that selectively inhibit glucose transporter 1 (GLUT1), methods for preparing the compounds, pharmaceutical compositions and combinations containing the compounds, and uses of the compounds for preparing pharmaceutical compositions for treating or preventing diseases , and intermediate compounds useful in the preparation of said compounds. [0002] Background of the invention [0003] Glucose is an essential substrate for metabolism in most cells. Because glucose is a polar molecule, transport across biomembranes requires specific transporters. Glucose transport across the apical membrane of intestinal and renal epithelial cells depends on secondary active Na + / the presence of glucose symporters SGLT-1 and SGLT-2, which concentrate glucose inside the cell, using Na + The energy provided by the co-transport of ions along their electrochemical gradient. Additionally, the facilitated diffusion of glucose across cell membranes ...
