That news spurred the European Medicines Agency (EMA) and researchers worldwide to investigate the possibility of a causal connection
Interaction With Appetite and Metabolic Signaling The ghrelin receptor mediates appetite regulation, and GHS-R1a agonists as a class can influence orexigenic signaling

Single and dual agonists The fundamental difference between these two molecules is that semaglutide is a GLP-1 agonist, i.e., it has a strong structural similarity (95%) with this hormone and specifically activates its receptor, while tirzepatide is a dual agonist, i.e., it has a hybrid structure that allows it to activate both GLP-1 and GIP receptors (Figure 2)
This unexpected result suggests that compounds like harmine, 2-2c, and 5-IT might target other unknown entities beyond DYRK1A
