β-Arrestins are a class of proteins that play a crucial role in the regulation of G-protein coupled receptors (GPCRs). GPCRs are a large family of receptors that detect molecules outside the cell and activate internal signaling pathways in response. They are involved in a myriad of physiological processes and are the targets of a significant portion of modern medicines. Among the β-arrestins, β-arrestin-2 stands out for its specific regulatory functions. When a GPCR is activated by its ligand, β-arrestin-2 is recruited to the receptor, leading to receptor desensitization, internalization, and sometimes initiating separate signaling cascades independent of G-proteins.

β-Arrestin-2 inhibitors are molecules specifically designed to impede the activity or interaction of β-arrestin-2 with GPCRs or other associated proteins. By inhibiting β-arrestin-2, these compounds can modulate the desensitization and internalization of GPCRs, altering the duration and intensity of receptor signaling. Furthermore, since β-arrestin-2 can initiate its own signaling pathways, independent of G-proteins, its inhibitors can also influence these β-arrestin-2-mediated pathways. The exact mechanisms by which these inhibitors operate can vary. Some might prevent the binding of β-arrestin-2 to GPCRs, while others might disrupt its interaction with other intracellular signaling proteins.
