GLP-1 1.03 pM (EC50) |
SAR441255 (30 min) TFA acts as a potent, balanced agonist of human GLP-1R, GCGR, and GIPR in recombinant HEK293 cells, with EC50 values of 1.03 pM, 1.01 pM, and 0.73 pM respectively[1].
SAR441255 TFA potently activates endogenous human GLP-1R in 1.1B4 pancreatic cells (EC50 27 pM), GCGR in primary human hepatocytes (EC50 2100 pM), and GIPR in human adipocytes (EC50 42 pM)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
SAR441255 (3-11 μg/kg; s.c.; once daily; 42 days) TFA induces significant body weight loss and improves glycemic control in obese, diabetic Macaca fascicularis monkeys over 42 days of treatment[1].
SAR441255 (11 μg/kg; s.c.; single dose) TFA achieves significant in vivo occupancy of GLP-1 receptors in the pancreas and glucagon receptors in the liver of lean cynomolgus monkeys[1].
SAR441255 (3-300 μg/kg; s.c.; once daily; 4 days) TFA causes transient, dose-related increases in heart rate and slight, sustained decreases in systolic blood pressure in lean telemetered cynomolgus monkeys[1].
SAR441255 (0.3-30 μg/kg; s.c.) TFA reduces body weight in a dose-dependent manner[2].
