casdatifan (AB521)
Arcus Biosciences recently disclosed the structure and discovery story of their oral HIF-2α inhibitor casdatifan (AB521) at the ACS Fall 2024 First Time Disclosures session in Denver. Read on to find out how the team overcame serum shifts and metabolism issues to deliver into the clinic what could potentially be a best-in-class compound, superior to the recently approved inhibitor, belzutifan.
VVD-130037
KEAP1 inhibition/NRF2 activation has been hotly pursued in recent years for immunology indications; however, in oncology, NRF2 degradation has been posited as a novel therapeutic mechanism for specific cancers. Vividion has already disclosed work on covalent KEAP1 inhibitors, but at the recent ACS Fall 2024 meeting, the structure and discovery story of their clinical oral covalent activator of KEAP1 were disclosed, identified through careful analysis of the data from their inhibitor screen.
BBO-8520
BridgeBio’s BBO-8520 is a selective, covalent KRAS(G12C) inhibitor which differentiates itself from the pack by engaging the (ON) state of the protein, potentially conferring increased clinical benefit in KRAS(G12C)-driven cancers, including overcoming resistance to current treatments. Disclosed at the 2024 AACR Annual Meeting in San Diego, is currently in a Ph. I trial in patients with advanced non-small-cell lung cancer. This article covers the structure, mechanism of action and preclinical efficacy that marks this compound out as one to watch.
aleniglipron
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.
NVL-520
Nuvalent’s lead compound, NVL-520, is an oral, brain-penetrant, TRK-sparing, and potential best-in-class ROS1 kinase inhibitor that recently entered Ph. II of the ARROS-1 trial (NCT05118789) in patients with advanced ROS1-positive NSCLC. This article highlights what makes the Nuvalent’s NVL-520 program scientifically notable, including what gives it a potential best-in-class profile as a ROS1 inhibitor, the emerging toxicology of hard-to-avoid off-targets, an interesting synthetic route to the small macrocycle, and more.
