Infection with the malaria parasite, Plasmodium falciparum, is a leading cause of fatality in the tropical regions of the world, with over 240M infections and >600k deaths each year. Currently, over half of the world population is at risk of infection and with the rise of resistance against current treatments, the need for new antimalarials is clear. At the ACS Fall 2024 conference in Denver, CO, Novartis outlined the structure and discovery story of NVP-IWY357, a novel antimalarial that has no cross-resistance to current drugs and the potential to achieve a single-dose cure.

AstraZeneca recently disclosed the structure and discovery journey of their oral small molecule PCSK9 inhibitor, AZD0780, during the ACS Fall 2024 First Time Disclosures session in Denver. Discover how the team identified a fragment hit targeting a previously unexplored pocket, verified its novel mechanism of action, and successfully advanced it into a clinical compound now in Ph. II trials for patients with dyslipidemia.

Vorasidenib (AG-881) is a brain-penetrant allosteric inhibitor of mutant isocitrate dehydrogenases 1 and 2 (mIDH1/2) from Agios and Celgene that made headlines summer 2023 due to its stunning efficacy for treatment of glioma in patients with mIDH1/2. This Featured Case Study reviews how it was discovered, how it works, and why it matters.

RLY-2608 is an oral, mutant-selective PI3Kα allosteric inhibitor from Relay Therapeutics. Current FDA-approved PI3Kα modulator (alpelisib) and a clinically advanced molecule (inavolisib) are limited by their off-target toxicities associated with the inhibition of WT PI3Kα, leading to hyperglycemia and rash. RLY-2608 is currently in a Ph. I as a single agent and in combination with fulvestrant for HR+/HER2- breast cancer treatment. This article reviews the discovery of RLY-2608, its mechanism of mutant selectivity, how it compares to other molecules, recent clinical developments, and more.

Bomedemstat (MK-3543, IMG-7289) is Merck’s irreversible LSD1 (lysine-specific demethylase 1) inhibitor for MPNs.
