Zenagamtide
Zenagamtide (Amycretin; NN 9487) is an orally active, blood-brain barrier permeable triple agonist that targets GLP-1, amylin (Amylin Receptor) and calcitonin receptor (Calcitonin Receptor). Zenagamtide is a single peptide consisting of 68 amino acids that can target brain regions regulating food intake, significantly suppress appetite and reduce energy intake. Therefore, Zenagamtide improves body weight, waist circumference, glycated hemoglobin and lipid profile, and also alleviates the histological features of metabolic dysfunction-associated steatotic liver disease (MASLD) and enhances insulin sensitivity. Zenagamtide may cause transient increases in heart rate and fluctuations in serum calcium levels, but it is an important compound for the study of overweight, obesity, insulin resistance and related metabolic diseases.

Biological Activity
Zenagamtide activates GLP-1, amylin and calcitonin receptors in cellular systems of humans, mice and rats[1].
Zenagamtide (10-fold to 3-fold serial dilution; 30 min-3 h) potently activates human, mouse and rat GLP-1R, mouse and rat AMY3 (a)R, as well as mouse and rat CTR, with EC50 values ranging from 8.4×10-13 M to 7.8×10-11 M[2].
Zenagamtide (10-fold serial dilution; 30 min) potently activates human AMY1 (a)R, AMY2 (a)R, AMY3 (a)R, and CTR (a), with EC50 values ranging from 1.30×10-12 M to 1.72×10-11 M[2].

Zenagamtide (10 nM/kg; subcutaneous injection; single dose) reduces 48-hour cumulative food intake by 50% in normal-weight male Sprague Dawley rats [2].
Zenagamtide (2-10 nM/kg; s.c.; twice daily; for 21 consecutive days) decreases total food intake by 23-30% in male DIO C57Bl/6J mice, and induces a dose-dependent, vehicle-adjusted body weight loss of 15.8-21.3% [2].
Zenagamtide (1, 3, 10 nM/kg; s.c.; once daily; for 21 consecutive days) reduces total energy intake by 47.4% in male DIO Sprague Dawley rats and achieves an 18.3% vehicle-adjusted body weight reduction while maintaining total energy expenditure [2].
Zenagamtide (1, 3, 10 nM/kg; s.c.; once daily; for 35 consecutive days) lowers HOMA-IR by 47% and increases steady-state glucose infusion rate threefold in male DIO Sprague Dawley rats, indicating improved insulin sensitivity [2].
Zenagamtide (10-30 nM/kg; s.c.; twice daily; for 12 weeks) reduces plasma liver enzyme levels, improves MASLD activity scores in 55.6%-64.7% of mice, and decreases liver inflammation and fibrosis markers in biopsy-confirmed GAN DIO-MASH male C57BL/6JRj mice [2].
Fluorescently labeled Zenagamtide (100 nM/kg; i.v.; single dose) reaches key brain regions involved in energy intake regulation in male C57BL/6J mice, including circumventricular organs, the hypothalamus, and hindbrain regions [2].
