A First-in-Class TRPA1 Antagonist Overcomes Toxicity Hurdles to Become Cough Candidate

The highly anticipated First Time Disclosures session at the ACS Spring 2024 Meeting in New Orleans, organized by Nicole Goodwin and H. Rachel Lagiakos, presented a variety of new orally available small molecules. In case you missed any of these exciting molecules, from Oric’s CD73 inhibitor to Deciphera’s first-in-class ULK1/2 inhibitor, this article provides the structures and targets for the novel molecules disclosed at the session.

The team reviews hundreds of compounds from thousands of papers, press releases, and other sources each month to select candidates for Molecules of the Month. Here we have compiled a table of >70 additional molecules that were of interest in January 2024 along with highlights from some of our favorites, including molecules targeting SOS1, NLRP3, SMARCA2, and more.

The "New Drugs on the Horizon" sessions at the AACR Annual Meeting 2024 in San Diego revealed twelve innovative oncology agents and offered attendees a first look at their structures and preliminary data as they enter/progress in the clinic. In case you missed any of these exciting compounds – including selective CDK inhibitors, molecular glues, bifunctional degraders, a radiopharmaceutical, a bifunctional antibody, and an ADC – this article covers the structures and targets disclosed. A separate session disclosed the structure of a pan-RAS isoform inhibitor with remarkable clinical results.

Momelotinib is a JAK inhibitor approved by the FDA in September 2023 for treating myelofibrosis. Last year, the molecule’s co-inventors, Andrew Wilks and Christopher Burns, gave a Drug Hunter Flash talk about the development of this drug with a fascinating mechanism of action.

In celebration of the molecule’s advancement, here we recap their brilliant story, including Wilks’ discovery of the JAK kinases and how he gave them their name, and the long, sometimes fraught journey of momelotinib through several companies before its acquisition and commercialization by GSK.

STC15 is Storm Therapeutics' first-in-class and first-to-clinic inhibitor of the post-transcriptional RNA modifier, METTL3, which progressed from HTS hit to clinical development in less than three years. METTL3 inhibitors have been previously identified, but no METTL3 inhibitors have entered clinical development until now. In this article, we explore METTL3 as a therapeutic target, highlight the discovery story of STC15, its fascinating mechanism of action, provide the latest clinical development update, and much more.
