zuranolone
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.
TAK-041
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 [...]
CVN293
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
LTGO-33
LTGO-33 is a state-independent NaV1.8 inhibitor with over 600-fold selectivity for the NaV1.8 channel over other sodium channels. Chronic pain affects millions, and existing treatments offer limited efficacy, risk of abuse, and low tolerability. There is an urgent need for new drugs that target validated pain mechanisms such as NaV1.8, which has recently gained increased attention. This article explores the unique pharmacological properties of LTGO-33, setting it apart from earlier NaV1.8 inhibitors.
KLS-13019
KLS-13019 is a CBD (cannabidiol) analogue and GPR55 (G protein-coupled receptor 55) antagonist from Kannalife Sciences, which shows promise as a novel therapeutic for neuropathic pain, particularly chemotherapy-induced neuropathic pain.
