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.

The rising impact of biomarkers in early clinical development

Drug Target Review

However, standard preclinical safety assessment studies may not accurately predict adverse events in humans, particularly with emerging modalities like precision medicine targeting human antigens or genes not present in preclinical species. For use as endpoints, biomarkers must be correlated to a valid clinical outcome.

Re-Imagining Med Chem Strategies: the Tyranny of the n+1 Compound

DrugBaron

Finding small molecule drugs is much harder than finding a needle in a haystack – discovering the right arrangement of atoms to bind precisely to a protein target to elicit a particular response is a problem of vast dimensionality. Yet the situation with small molecules is even worse.

Looking beyond traditional oncogenic pathways to break cancer resistance

Drug Target Review

4 Another related and well described non-oncogene resistance mechanism is the histological transformation of EGFR-mutated non-small cell lung cancer (NSCLC) to small-cell lung cancer upon treatment with an EGFR inhibitor. 5 Here, the original oncogene is still present but the transdifferentiated cancer cells are less dependent on it.

Antibody-drug conjugates payloads: then, now and next

Drug Target Review

Groundbreaking strategies like proteolysis-targeting chimeric molecules (PROTACs) are also being explored. 6 Combining the effect of payloads with different mechanisms of action – an approach that revolutionised small molecule chemotherapy – also holds the promise of enhanced therapeutic activity for ADCs. 161 , 416–432 (2019).
