Biological Activity

LY3437943 is a triple agonist peptide of the glucagon receptor (GCGR), glucosedependent insulinotropic polypeptide receptor (GIPR), and glucagon-like peptide-1 receptor (GLP-1R). LY3437943 inhibits for human GCGR, GIPR, and GLP-1R with EC50 values of 5.79, 0.0643 and 0.775 nM, respectively. LY3437943 can be used for the research of obesity.

In Vitro

LY3437943 has inhibition for human GCGR, GIPR, and GLP-1R with EC50 values of 5.79, 0.0643 and 0.775 nM, respectively[1]. LY3437943 has inhibition for mouse GCGR, GIPR, and GLP-1R with EC50 values of 2.32, 0.191 and 0.794 nM, respectively[1]. LY3437943 has binding affinity for human GCGR, GIPR, and GLP-1R with Ki values of 5.6, 0.057 and 7.2 nM, respectively[1]. LY3437943 has binding affinity for mouse GCGR, GIPR, and GLP-1R with Ki values of 73, 2.8 and 1.3 nM, respectively.

In Vivo

LY3437943 (s.c.; 0.47 mg/kg; single) engages GCGR in vivo and can improve glucose tolerance in an ipGTT through either the GIP or GLP-1 receptors[1]. LY3437943 (s.c.; 10 mL/kg; cycle every 3 days; for 21 days) causes great body weight loss and increases energy expenditure through glucagon receptor activatio[1]. LY3437943 has safety and tolerability[1]. Animal Model: Male CD-1 mice[1] Dosage: 0.47 mg/kg Administration: Subcutaneous administration, single Result: AUClast, ng*h/mL AUC0-∞, ng*h/mL Cmax, ng/mL Tmax, h t1/2, h CLF, mL/h/kg 41135 41905 1680 12 21 11.22 Animal Model: Diet-induced obese (DIO) male C57/Bl6 mice (24-25 weeks, 40-51 g)[1] Dosage: 10 mL/kg Administration: Subcutaneous (SC) injection, cycle every 3 days, for 21 days Result: Decreased body weight and improved glycemic control.
