Researchers created a DNA-encoded peptoid library using tryptophan mimics to discover new protein inhibitors. This method identified inhibitors for MDM2 and a novel class targeting TEAD-YAP interactions, impacting gene expression.
Area of Science:
- Medicinal Chemistry
- Chemical Biology
- Molecular Biology
Background:
- The indole side chain of tryptophan is crucial in protein-protein interactions.
- DNA-encoded combinatorial synthesis offers efficient exploration of chemical space.
Purpose of the Study:
- To design and synthesize a DNA-encoded peptoid library using tryptophan mimics.
- To identify inhibitors of tumor-relevant proteins MDM2 and TEAD4.
Main Methods:
- Ugi four-component reaction for peptoid synthesis.
- Azide-alkyne cycloaddition for library diversification.
- DNA-encoded selection for target protein binders.
Main Results:
- A library of 8112 DNA-encoded peptoids was synthesized.
- Identified specific binders for MDM2.
- Discovered a novel class of TEAD-YAP interaction inhibitors.
Conclusions:
- DNA-encoded peptoid libraries are effective for discovering protein-protein interaction modulators.
- The identified TEAD-YAP inhibitors offer a new approach to modulate Hippo pathway signaling.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
