    Retatrutide (LY3437943) acetate is a triple agonist peptide for the glucagon receptor (GCGR), glucose-dependent insulinotropic polypeptide receptor (GIPR), and glucagon-like peptide-1 receptor (GLP-1R).

    Retatrutide acetate inhibits human GCGR, GIPR, and GLP-1R with EC50 values of 5.79, 0.0643, and 0.775 nM, respectively. It exhibits activity on mouse GCGR, GIPR, and GLP-1R with EC50 values of 2.32, 0.191, and 0.794 nM, respectively.

    In vivo, Retatrutide (LY3437943) acetate engages with GCGR and enhances glucose tolerance in an ipGTT by acting through GIP or GLP-1 receptors. Activation via the glucagon receptor by Retatrutide acetate leads to significant weight reduction and increased energy expenditure. Retatrutide acetate can be utilized in research related to obesity.

    Mechanism of Action and Molecular Structure of Retatrutide:

    Triple Agonist Design
    - GLP-1 receptor: Retatrutide delays gastric emptying, suppress appetite, and promote insulin secretion.
    - GIP receptor: Retatrutide enhances insulin sensitivity and regulate central satiety signals.
    - Glucagon receptor (GCGR): Retatrutide activates liver energy metabolism, promote lipolysis and glycogenolysis, and increase basal metabolic rate.
    The triple synergistic effect increases energy consumption while reducing energy intake, significantly improving weight loss effects.

    Indications and Efficacy:

    ★ Obesity Treatment:
    In the Phase II clinical trial, patients in the highest dose group (12 mg) lost an average of 24.2% weight after 48 weeks, and some patients lost more than 30%.

    ★ Metabolic Dysfunction-Associated Fatty Liver Disease (MASLD):
    Retatrutide can reduce liver fat content by 86%, and more than 85% of patients achieve regression of liver steatosis.

    ★ Type 2 Diabetes:
    Significantly reduce glycated hemoglobin (HbA1c) and improve blood sugar control.

    ★ Potential Cardiovascular Benefits:
    Animal studies have shown that it may indirectly protect cardiovascular health by improving blood pressure and heart function, but further clinical verification is needed.

    ECHEMI Editorial Reference
    Retatrutide is a novel triple agonist peptide of the glucagon receptor (GCGR), glucose-dependent insulinotropic polypeptide receptor (GIPR) and glucagon-like peptide-1 receptor (GLP-1R). Retatrutide inhibits human GCGR, GIPR and GLP-1R with EC50 values of 5.79, 0.0643 and 0.775 nM, respectively and mouse GCGR, GIPR, and GLP-1R with EC50 values of 2.32, 0.191 and 0.794 nM, respectively. It is an important tool for obesity research.Retatrutide potently activates the GLP-1R signaling pathway to stimulate glucose-dependent insulin secretion through activity at the GIP receptor (GIPR) or the GLP-1R.Retatrutide is a synthetic peptide with glucose-lowering effects. It is an antidiabetic agent against type 2 diabetes (T2D), stimulating insulin and suppressing glucagon secretion in a glucose-dependent manner.Retatrutide was also shown to delay gastric emptying, lower fasting and postprandial glucose concentration, decrease food intake and reduce body weight in patients with type 2 diabetes.
