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

The Takeda GPR139 agonist, TAK-041 , is a CNS-penetrant GPCR agonist being explored for schizophrenia symptoms and is an interesting example of a triazinone-containing clinical candidate. GPR139 is an orphan GPCR that’s highly expressed in the human habenula, which plays a major role in avoidance behavior. Lesions in the habenula cause [...]

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.

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

Zuranolone (ZURZUVAE™) is an oral positive allosteric modulator of CNS GABA signaling developed by Sage Therapeutics, in collaboration with Biogen, which was approved in August 2023 by the FDA for the treatment of postpartum depression (PPD). In 2019 Sage had received approval for brexanolone (ZULRESSO™), an IV formulation of the endogenous GABA PAM neurosteroid hormone for PPD, but an oral drug is expected to greatly increase access to treatment. Zuranolone was also investigated for major depressive disorder, although the FDA declined to extend approval for this indication.
