COP1 Activators

The chemical class of COP1 activators, as listed here, is largely focused on compounds that influence protein degradation pathways and cellular signaling processes. This class includes several proteasome inhibitors such as MG132, Lactacystin, Epoxomicin, and Bortezomib. These compounds inhibit the proteasome, a complex responsible for degrading proteins tagged for destruction, a process in which COP1 is directly involved. By inhibiting the proteasome, these compounds can indirectly affect the activity of COP1, particularly its role in targeting specific proteins for degradation.

Furthermore, this class encompasses compounds that modulate other aspects of cellular signaling and stress responses. Withaferin A, Curcumin, and Resveratrol are examples of natural compounds with broad biological activities, including the modulation of proteasomal and other degradation pathways. These compounds can indirectly influence COP1 activity by altering the cellular environment and the stability of proteins that interact with or are targeted by COP1. Additionally, HSP90 inhibitors like 17-AAG (Tanespimycin) and Geldanamycin are included in this chemical class. HSP90 is a molecular chaperone involved in the proper folding and stabilization of many proteins. Inhibiting HSP90 can lead to the destabilization of its client proteins, potentially impacting the proteins that interact with COP1 or are regulated by it.
