Jecure’s JT001 is a selective inhibitor of NLRP3 inflammasome and among the earlier compounds in this now highly competitive space. In 2018, Genentech bought Jecure Therapeutics for an undisclosed amount, gaining access to Jecure’s NLRP3 inhibitor JT001. While there are many other NLRP3 inhibitors now in the space, JT001 is an interesting example of an initial attempt to overcome liver toxicity with well-known NLRP3 inhibitor MCC950. However, the molecule ran into its own kidney toxicity issues, making this an intriguing toxicology case study.

ONL1204 is ONL Therapeutics' small peptide inhibitor of the Fas receptor for IRD.

Pfizer disclosed the structure and discovery of their oral small molecule BDK inhibitor/degrader, PF-07328948, during the ACS Fall 2024 First-Time Disclosures session in Denver. The team identified a thiophene carboxylic acid-based hit targeting an allosteric pocket on BDK. Through optimization, they overcame challenges such as potential IADRs and BDK-E2 complex stabilization. By manipulating the dihedral angle of the methoxy group, they enhanced binding interactions, verifying PF-07328948's unexpected mechanism of action in vivo. PF-07328948 is currently Ph. I trials.

The recently released WHO INN proposed names list includes the structure and name of Structure Therapeutics’ oral small molecule GLP-1R agonist, aleniglipron (GSBR-1290). Seemingly emerging from a “fast-follower” program based on Chugai/Eli Lilly’s orforglipron, the compound includes an unusual phosphine oxide motif and has shown positive results on plasma glucose levels and bodyweight in a Ph. IIa study.

Xanamem® is Actinogen Medical's cortisol-blocking drug targeting the 11β-HSD1 (11β-hydroxysteroid dehydrogenase) enzyme.
