KEAP1 inhibition/NRF2 activation has been hotly pursued in recent years for immunology indications; however, in oncology, NRF2 degradation has been posited as a novel therapeutic mechanism for specific cancers. Vividion has already disclosed work on covalent KEAP1 inhibitors, but at the recent ACS Fall 2024 meeting, the structure and discovery story of their clinical oral covalent activator of KEAP1 were disclosed, identified through careful analysis of the data from their inhibitor screen.

Sonrotoclax, BeiGene’s clinical-stage, orally bioavailable, next-generation inhibitor, targets both WT and mutated forms of the Bcl-2 protein by binding within a hydrophobic groove, similar to other inhibitors in its class. Explore this case study to see how sonrotoclax was rationally designed to potency against both WT and mutant Bcl-2 and address the limitations of first-generation inhibitors and more!

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.

Chiesi Farmaceutici’s CHF-6523 is an inhaled, lung-restricted, selective PI3Kδ inhibitor designed to provide relief to patients with COPD. Its development involved optimization of permeability and solubility as well as identification of a solid form amenable for dry powder inhalation. Disclosed at the EFMC-ISMC 2024 joint conference in Rome, Italy, this article covers the structure, development, and early clinical data of CHF-6523, which ultimately indicates that PI3Kδ inhibition may not provide clinical effect in reduction of lung inflammation.

Infection with the malaria parasite, Plasmodium falciparum, is a leading cause of fatality in the tropical regions of the world, with >240M infections and >600K deaths each year, the majority of which are in sub-Saharan Africa. The need for new antimalarials is clear, given that over half of the world's population is at risk of infection, combined with the rise of resistance against current treatments. Novartis has played a key role in this fight and at the ACS Fall 2024 meeting in Denver, CO, they disclosed NVP-FVP954: a novel, fast-acting IV antimalarial for severe malaria.
