Selective inhibition of USP7.

Area of Science:

• Biochemistry
• Molecular Biology
• Drug Discovery

Background:

• The deubiquitinating enzyme USP7 plays a critical role in cellular processes and is implicated in cancer and viral infections.
• Targeting USP7 presents a promising therapeutic avenue for various diseases.

Discussion:

• Reverdy et al. report the development of the first small-molecule inhibitor exhibiting selectivity for USP7.
• This novel inhibitor effectively mimics the effects of USP7 knockdown in cancer cells.

Key Insights:

• The study demonstrates that selective inhibition of USP7 can be achieved with small molecules.
• The inhibitor's ability to replicate knockdown phenotypes validates USP7 as a druggable target.

Outlook:

• This work paves the way for the clinical development of USP7-targeted therapies.
• Further research into USP7 inhibitors could lead to new treatments for oncology and antiviral applications.
