The Altos Therapeutics /Takeda D2/D3 receptor antagonist, TAK-906 , is a peripherally-restricted, non-BBB penetrant molecule, targeting the stomach and vomiting center in the area postrema to treat gastroparesis. Gastroparesis is a chronic condition characterized by delayed gastric emptying, resulting in nausea, vomiting, pain, and anorexia [...]

Pfizer has announced the FDA-approval of zavegepant ( ZAVZPRET TM , BHV-3500) for the treatment of acute migraine in adults based on positive Ph. II/III results. As the first and only calcitonin gene-related peptide (CGRP) receptor antagonist nasal spray [...]

Cerevance’s CVN293 is an oral, CNS-penetrant, selective inhibitor of potassium efflux-mediated NLRP3-inflammasome activation in microglia for the treatment of neurodegenerative disorders. Cerevance’s NETSseq platform was used to discover a microglia-specific potassium efflux channel, KCNK13, which allows modulation of the NLRP3-inflammasome in the CNS without affecting peripheral innate immunity. Read the full article to discover highlights on the CNS-penetration of highly polar compounds and how particle size can be key to oral bioavailability

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.

BAY 2925976 is a novel oral ARα2C antagonist developed by Bayer for the treatment of OSA (obstructive sleep apnea), a widespread condition affecting nearly one billion people globally. Despite the availability of mechanical treatments like CPAP, poor adherence rates highlight the need for more effective interventions. BAY 2925976 demonstrated a preclinical proof of concept for ARα₂C modulation as a potential therapeutic approach for OSA. In this article, we detail the discovery of BAY 2925976, as highlighted by Michael Hahn at the ACS Fall 2024 First-Time Disclosures session in Denver, CO.
