obicetrapib
Context. Obicetrapib (Monash University and NewAmsterdam Pharma) is an oral selective cholesteryl ester transfer protein (CETP) inhibitor being developed for dyslipidemia. Patients with high cardiovascular risk typically aim to lower cholesterol with a combination of statins, diet, and exercise, but this is often not enough . A foundational [...]
PF-07328948
Pfizer disclosed the structure and discovery of their oral small molecule BDK inhibitor/degrader, PF-07328948, during the ACS Fall 2024 First-Time Disclosures session in Denver. The team identified a thiophene carboxylic acid-based hit targeting an allosteric pocket on BDK. Through optimization, they overcame challenges such as potential IADRs and BDK-E2 complex stabilization. By manipulating the dihedral angle of the methoxy group, they enhanced binding interactions, verifying PF-07328948's unexpected mechanism of action in vivo. PF-07328948 is currently Ph. I trials.
asundexian (BAY2433334)
asundexian (BAY2433334) is a reversible Factor XIa active site inhibitor previously disclosed at the 2021 EFMC-ISMC conference . This article highlights the Ph. I data of asundexian in healthy volunteers, showing that the drug is well tolerated, with no clinically relevant bleeding-related adverse events or any relevant CYP3A4 modulation. The [...]
"compound 23"
“compound 23” is an oral, selective Factor XIa inhibitor intended as an anticoagulation agent. Since the clinical translatability of FXIa inhibition in preclinical models hasn’t been established, this program was driven by activity in in vitro human plasma coagulation assays. The team was able to turn a 0.6 uM hit originally from a complement [...]
AZD0780
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.
