Zunsemetinib (ATI-450, CDD-450) is a p38α- MK2 complex inhibitor discovered by Confluence Technologies and developed by Confluence spinout, Aclaris Therapeutics. The molecule has a unique molecular glue-like mechanism of action that held promise in immunology, but sadly recent results have led to its discontinuation. This article reviews the target, its mechanism, and why it mattered.

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.

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

Zilucoplan is a macrocyclic peptide-containing drug with 15 amino acids in total, targeting the challenging-to-drug C5 complement protein and formulated for self-administered once-daily SC injection. In Sept. 2023, zilucoplan received its first global approval in Japan, followed in Oct. 2023 by FDA approval for gMG patients who are AChR antibody-positive, making zilucoplan the first drug derived from mRNA display for cyclic peptides to be approved. This case study discusses how zilucoplan was discovered and why it’s an important scientific milestone for the industry.

The Janssen non-ATP competitive HPK1 inhibitor, “ compound 1 ,” was identified from a screening cascade specifically looking for allosteric inhibitors, which may provide a selectivity advantage over ATP-competitive starting points. Reviewer Adi Murthy says, “ Specificity may prove challenging for HPK active site inhibitors since it belongs to [...]
