Semaglutide Quick Facts: Drug Class: GLP-1 receptor agonist Brand Names: Ozempic (diabetes), Wegovy (weight loss), Rybelsus (oral) FDA Approval: Ozempic approved 2017, Wegovy approved 2021 Manufacturer: Novo Nordisk Dosing: Once weekly injection, starting at 0.25 mg, maximum 2.4 mg Clinical Trial Name: STEP trials (Semaglutide Treatment Effect in People with obesity) Average Weight Loss: 10-15% of body weight over 68 weeks Tirzepatide Quick Facts: Drug Class: Dual GIP/GLP-1 receptor agonist Brand Names: Mounjaro (diabetes), Zepbound (weight loss) FDA Approval: Mounjaro approved 2022, Zepbound approved 2023 Manufacturer: Eli Lilly Dosing: Once weekly injection, starting at 2.5 mg, maximum 15 mg Clinical Trial Name: SURMOUNT trials (Study to evaluate tirzepatide in obesity or overweight) Average Weight Loss: 15-22% of body weight over 72 weeks Primary Difference: The main distinction is that semaglutide activates only GLP-1 receptors, while tirzepatide activates both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptors

Nevertheless, if we compare the internal states corresponding to Nrf2Keap1 complexes (Fig 3D), the dissociation model predicts an immediate decrease in the complex upon exposure to DEM followed by a sharp increase in complex formation, while the hinge-latch model predicts a prolonged increase in the complex that starts immediately upon oxidative stress
