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

NT-0796 is NodThera's pro-drug inhibitor of the NLRP3 inflammasome. NT-0796 is currently in a Ph. Ib/IIa trial in obese individuals at risk of developing atherosclerotic cardiovascular diseases. NT-0796 has the potential to reduce neuroinflammation in Parkinson’s disease. The NLRP3 inflammasome has emerged as a hot target due to its connection to Alzheimer’s disease, Parkinson’s disease, gout, and other diseases. Here is a detailed review of the role of NLRP3 inhibition in treating atherosclerosis, how NT-0796 was identified, and what makes it special, clinical development, and more.

AZD4747 is a CNS-penetrant, oral KRAS G12C covalent inhibitor for the treatment of CNS-metastatic KRAS-mutant cancers. KRAS inhibitors have tended to be quite large and fall outside the range of physicochemical properties generally required for CNS permeability. (MW < 360 Da, cLogD < 2, TPSA < 90 Å2. AZD4747 is much smaller than marketed KRAS G12C inhibitors but maintains exceptional cellular potency. The team also encountered an unexpected toxicity that scientists working on covalents should pay attention to.

Compound 8 is a dual 5-HT2A and 5-HT2C receptor inverse agonist developed to address the limitations of pimavanserin.

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 [...]
