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

“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 [...]

BI-0115 inhibits the C-type lectin family member lectin-like oxidized LDL-receptor-1 (LOX-1) by stabilizing an inactive tetrameric form of the protein. Interestingly, co-crystollography demonstrates that inter-ligand interactions between two BI-0115 molecules contribute to the dimerization of LOX-1 homodimers.

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) 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 [...]
