[Intermolecular interaction-based ubiquitin-proteasome system-targeting drug discovery]

Area of Science:

• Biochemistry
• Molecular Biology
• Drug Discovery

Background:

• The Ubiquitin-Proteasome System (UPS) is a natural cellular mechanism for protein degradation.
• Targeting protein degradation offers a novel therapeutic strategy beyond traditional inhibition.

Purpose of the Study:

• To review recent advancements in UPS-based drug discovery.
• To introduce chimera-type small molecules (SNIPERs/PROTACs) for targeted protein degradation.
• To discuss novel technologies for identifying E3 binders and protein binders.

Main Methods:

• Review of current literature on UPS-based protein degradation technologies.
• Focus on chimera compound-based approaches (SNIPERs/PROTACs) and E3 modulator-based technologies.
• Discussion of emerging methods for identifying small molecule E3 binders and protein binders.

Main Results:

• UPS-based approaches, particularly chimera compounds, enable selective degradation of target proteins.
• Two main strategies exist: E3 modulator-based and chimera compound-based technologies.
• Novel methods facilitate the identification of key molecular components for targeted degradation.

Conclusions:

• Targeted protein degradation via UPS is a promising avenue for drug discovery.
• SNIPERs and PROTACs represent powerful tools for achieving selective protein knockdown.
• Continued innovation in identifying binding molecules will accelerate UPS-based therapeutic development.
