The Sanofi S1P1 agonist, SAR247799 , is a biased agonist of the S1P1 sphingosine receptor, preferentially activating G-protein signaling over the β-arrestin and internalization pathways. Commercial S1P1 modulators such as fingolimod and ozanimod exert their immunosuppressive effects in multiple sclerosis and other diseases primarily by [...]

BridgeBio’s acoramidis (Attruby), an oral, second-generation stabilizer of the TTR protein, has been approved by the FDA for the treatment of ATTR-CM (transthyretin amyloid cardiomyopathy). Amyloid deposits in the heart muscle characterize the rare but potentially fatal disease. This case study reviews the history of TTR modulation, early experiments validating the therapeutic potential of TTR stabilization, the binding mechanism of acoramidis to TTR, the importance of binding enthalpy for differentiation, and the molecule’s impressive 30-month clinical data following an early scare.

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.

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.

BAY 2413555 is a M2R PAM that has the potential to counter parasympathetic withdrawal and restore autonomic balance in heart failure patients. The preclinical and clinical data of BAY 2413555 showed it has positive effects on heart rate and heart rate variability and a relatively long human t1/2 of 37 h. The Ph. I trial, however, was terminated in March 2024 due to findings from a chronic toxicology study. This article covers the discovery of BAY 2413555, presented by Alexandros Vakalopoulos of Bayer at the EFMC-ISMC 2024 conference in Rome and published in the Journal of Medicinal Chemistry.
