Empagliflozin (BI 10773)是一种有效的,选择性SGLT-2抑制剂,IC50为3.1 nM,比作用于SGLT-1, 4, 5和6选择性高300倍以上。Phase 3。
Information
Empagliflozin (BI-10773) is a potent and selectiveSGLT-2inhibitor withIC50of 3.1 nM, exhibits >300-fold selectivity over SGLT-1, 4, 5 and 6. Phase 3. In vitro
Empagliflozin shows >2500-fold selectivity for hSGLT-2 over hSGLT-1 (IC50 8300 nM) and >3500-fold selectivity over hSGLT-4, it exhibits >350-fold selectivity over hSGLT-5 (IC50=1100 nM) and >600-fold selectivity over hSGLT-6. No relevant inhibition of GLUT1 is observed up to 10 μM Empagliflozin. In a kinetic binding experiments, [3H]-empagliflozin displays a high affinity for SGLT-2 with a mean Kd of 57 nM in the absence of glucose, and shows a half-life of [3H]-empagliflozin-binding to SGLT-2 of 59 min in the absence of glucose.Its binding to SGLT-2 is competitive with glucose.
