Strategies for targeting undruggable targets

Area of Science:

• Drug discovery and development
• Molecular biology
• Pharmacology

Background:

• Undruggable targets are clinically significant but difficult to modulate with traditional methods due to unique structural and functional characteristics.
• These targets often lack defined binding pockets or function through protein-protein interactions, posing challenges for conventional drug design.

Purpose of the Study:

• To review the concept of undruggable targets and present innovative strategies for their therapeutic targeting.
• To explore novel drug discovery technologies and therapeutic entities applicable to these challenging targets.

Main Methods:

• Review of existing literature on undruggable targets and emerging therapeutic modalities.
• Analysis of case studies involving targets like Bcl-2, p53, and RAS.
• Discussion of unconventional drug discovery approaches, including targeted degradation and display technologies.

Main Results:

• Identification of key characteristics that define undruggable targets.
• Illustration of strategies involving novel therapeutic entities and advanced drug discovery technologies.
• Demonstration of the feasibility of targeting undruggable proteins through specific examples.

Conclusions:

• Targeting undruggable proteins broadens the landscape of treatable diseases and signifies the forefront of drug discovery.
• Integration of diverse discovery approaches and novel therapeutic entities is crucial for overcoming challenges posed by undruggable targets.
