usp5-in-1

USP5-IN-1 (compound 64) is a potent deubiquitinase USP5 inhibitor that binds to the USP5 ZnF-UBD with a KD of 2.8 μM and is selective over nine proteins containing structurally similar ZnF-UBD domains. Additionally, USP5-IN-1 inhibits the USP5 catalytic cleavage of a di-ubiquitin substrate [1].

Vialinin A (Terrestrin A), a p-terphenyl compound, exhibits antioxidant properties and acts as a potent inhibitor of TNF-α, USP4, USP5, and sentrin SUMO-specific protease 1 (SENP1). Its efficacy in autoimmune diseases and cancer research is noteworthy, highlighting its potential therapeutic applications.
