Computational Partnership in Small Molecule Drug Discovery
The real magic happens when chemists can integrate computational models into their assay cascades, thanks to trust in their predictions. To get there, grounding computational predictions in physics and experimental reality makes all the difference. In this article, Abba E. Leffler, Ph.D. from Schrödinger tells us about: How to make [...]
Small Molecules Evolve
Small molecule drugs make up most of the drugs we take conveniently as pills, including painkillers like ibuprofen (Advil), antibiotics like penicillin and amoxicillin, or cholesterol-lowering drugs like atorvastatin (Lipitor). The biotechnology revolution allowed scientists to create drugs through genetic engineering and related biological processes, creating a new category of drugs known as “biologics.”...
Olutasidenib: Potentially Longer Complete Remissions in AML with a Second-Generation IDH1 Inhibitor
Olutasidenib, discovered by Forma Therapeutics and marketed by Rigel, is an oral, brain-penetrant, selective mIDH1 inhibitor. It was granted Orphan Drug Designation and approved in December 2022 by the FDA for adults with relapsed/refractory acute myeloid leukemia. Approval was granted based on a Ph. I/II trial showing a 35% CR+CRh rate and a favorable 25.9-month median duration. This article describes the discovery and development of olutasidenib, how it is distinct from other mIDH inhibitors, and its potential in treating gliomas.
Are Drugs Becoming More Lipophilic Over Time?
Drug lipophilicity is a core property that contributes to drug solubility, permeability, metabolic disposition, and other key properties. Increasing lipophilicity can often lead to increased affinity in relevant biological assays due to the hydrophobic nature of many protein binding pockets, but this may also increase promiscuity to [...]
Where Do Recent Small Molecule Clinical Candidates Come From?
Modern hit-finding technologies are incredible. Dean Brown and Jonas Bostrom at AstraZeneca have a very nice review out summarizing the hit-finding strategies for 66 clinical candidates published from 2016-2017. Some highlights include a clinical candidate from DNA-encoded libraries at GSK, the discovery of an RNA-binding drug candidate by [...]
