LUNA18 is an orally bioavailable, cell-penetrant, macrocyclic peptide pan-RAS inhibitor (Chugai ’21Q3 earnings call) intended for the treatment of KRAS-mutant cancers. It disrupts the protein-protein interaction between KRAS and SOS, preventing RAS activation.

Nerandomilast (BI 1015550) is Boehringer Ingelheim’s PDE4B inhibitor with demonstrated clinical potential in treating IPF.

The BMS factor XIa inhibitor, milvexian (BMS-986177), is an oral antithrombotic with a Ki of 0.11 nM. A member of this macrocyclic series was previously highlighted as one of 2020’s Molecules of the Year . Poor pharmaceutic properties from previous preclinical molecules such as solubility were addressed resulting in this candidate. Milvexian [...]

Recently, a surge of (pre)clinical compounds inhibiting the NLRP3 inflammasome, often featuring a hexahydroindacene ring system, has emerged, including Nodthera’s ND-0796. In a push for new chemotypes, AZ and Mitsubishi Tanabe have disclosed their clinical compound, AZD4144, which is currently in Ph. I trials in healthy volunteers. The discovery story detailed their efforts to overcome PLD (phospholipidosis), genotoxicity, and hERG inhibition in a non-classical pharmacophore series. The discovery was presented by Anders Johansson at the EFMC-ISMC 2024 Meeting in Rome.

Novartis' NLRP3 inhibitor, NVP-DFV890, features a unique sulfonimidamide motif designed to reduce hydrolysis relative to traditional sulfonylureas. This potent compound, with promising PK in humans, is advancing through multiple clinical studies, including Ph. II trials for coronary heart disease and knee osteoarthritis. Presented by Angela Mackay at the EFMC-ISMC 2024 joint conference in Rome, this overview covers NVP-DFV890's discovery, as well as its preclinical PK and PD data.
