Analyzing Oxygen Atom Distribution in FDA‐Approved Drugs to Enhance Drug Discovery Strategies

Chemical Biology and Drug Design

This work presents a comprehensive analysis of oxygen atoms in approved drugs, aiming to streamline drug design and discovery efforts. The study examines the frequency, distribution, prevalence, and diversity of oxygen atoms in a dataset of 2049 small molecules approved by the FDA and other agencies.

Development of a Covalent Small Molecule Downmodulator for the Transcription Factor Brachyury

Covalent Modifiers

Recently, afatinib, an FDA-approved kinase inhibitor, has been shown to modulate brachyury levels in multiple chordoma cell lines. Given that direct pharmacological intervention against brachyury has proven difficult, attempts at intervention have instead targeted upstream kinases.
