4.5 Billion Molecules, One Mission: Cure the ‘Undruggable’ Diseases

Solving the “Undruggable” Disease Problem with Goldilocks Molecules

In this episode, Christian Schafmeister, Founder and President of Third Law Molecular, reveals a new class of therapeutics designed to target what most consider “undruggable” diseases—conditions like Alzheimer’s, certain cancers, and rare genetic disorders.

Christian explains the science behind spiroligomers—modular, mid-sized molecules that act like molecular LEGOs, offering the perfect balance between small molecules and biologics. Learn how his team created a library of 4.5 billion molecules and what makes these structures uniquely suited to bind difficult protein targets, including disordered proteins and intracellular surfaces.

We also talk about the Goldilocks Zone of drug design, how Third Law’s chemistry was born out of academic and defense-backed research, and why the future of drug discovery may lie in designing therapeutics that are just right.
