Molecular Glues in Therapy

Molecular glues are a new class of drugs that can treat protein interfaces as druggable objects, offering a fundamental rewiring of cellular machinery. This episode explores the world of molecular glues, their mechanism of action, and how AI is being used to design them. With the potential to treat diseases driven by undruggable proteins, molecular glues are redefining what a drug can do inside the human body.

Key Concepts

Molecular Glues

Molecular glues are a new class of drugs that can treat protein interfaces as druggable objects.
They work by inducing or stabilizing a ternary complex, a three-part interaction between the drug, the target disease protein, and a specific effector protein.

Mechanism of Action

Molecular glues bind to one protein, fundamentally altering its topography, and making it attractive to a completely different protein.
The binding of the molecular glue creates a new, shared thermodynamic state, which can lead to the degradation of the disease protein.

AI-Driven Design

AI is being used to design molecular glues, using techniques such as biased libraries and DNA-encoded libraries.
AI can predict the binding affinity of a molecular glue to a target protein, and can design new glues with improved affinity and selectivity.

Therapeutic Applications

Molecular glues have the potential to be used to treat a wide range of diseases, including cancer.
They could be used to treat diseases driven by undruggable proteins, which make up about 80% of the human proteome.

Future Directions

Molecular glues could be used as programmable, ingestible switches to control biological processes on demand.
They could be used to reprogram the human body as a biological computer, allowing for the dynamic assembly of new synthetic biological machines.
