Customer Review

Based on 1 Customer Validation

Zenagamtide (Amycretin; NN 9487) sodium is an orally active, blood-brain barrier permeable triple agonist that targets GLP-1, Amylin Receptor and Calcitonin Receptor. Zenagamtide sodium 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 sodium 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 sodium 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.

In Vitro

Zenagamtide (Amycretin; NN 9487) sodium activates GLP-1, amylin, and calcitonin receptors in human, mouse, and rat cell systems^[1].
Zenagamtide (30 min-3 h) sodium potently activates human, mouse, and rat GLP-1R, mouse and rat AMY_{3 (a)}R, and mouse and rat CTR, with EC₅₀ values ranging from 8.4×10^-13 M to 7.8×10^-11 M^[2].
Zenagamtide (30 min) sodium potently activates human AMY_{1 (a)}R, AMY_{2 (a)}R, AMY_{3 (a)}R and CTR_(a), with EC₅₀ values ranging from 1.30×10^-12M to 1.72×10^-11M^[2].

Zenagamtide (1-10 nmol/kg; s.c.; once daily; for 35 days) sodium reduces HOMA-IR by 47% and increases the steady-state glucose infusion rate 3-fold in male diet-induced obese (DIO) Sprague Dawley rats, suggesting improved insulin sensitivity^[2].
Zenagamtide (10-30 nmol/kg; s.c.; twice daily; for 12 weeks) sodium reduces plasma liver enzyme levels, improves the MASLD activity score 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].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
