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.

The Merck CETP inhibitor backup, MK-8262 , is potential best-in-class CETP inhibitor, which was only discontinued as a backup due to the success of its predecessor, anacetrapib in Ph. III. Reviewer Kim Huard thought this CETP inhibitor was a great piece of work from Merck, and is a great example how to deal with a very lipophilic binding site [...]

Merck’s macrocyclic PCSK9 protein-protein interaction (PPI) inhibitor, MK-0616, is a once-daily PCSK9-lowering and LDL-cholesterol-lowering small molecule that has recently demonstrated antibody-like efficacy as an oral agent in the clinic. The program highlights numerous technical achievements at the forefront of modern drug discovery, and will set a standard for modern “classics in drug discovery” for some time.

The Turning Point Therapeutics oral, brain-penetrant ALK/ROS1/TRK kinase inhibitor, repotrectinib (TPX-0005), is a macrocyclic molecule with a small size intended to limit adverse interactions with resistance mutation hotspots near kinase active sites. TRK fusion proteins are driver mutations in certain cancers (which respond well to [...]

Recently, a surge of (pre)clinical compounds inhibiting the NLRP3 inflammasome, often featuring a hexahydroindacene ring system, has emerged, including Nodthera’s ND-0796. In a push for new chemotypes, AZ and Mitsubishi Tanabe have disclosed their clinical compound, AZD4144, which is currently in Ph. I trials in healthy volunteers. The discovery story detailed their efforts to overcome PLD (phospholipidosis), genotoxicity, and hERG inhibition in a non-classical pharmacophore series. The discovery was presented by Anders Johansson at the EFMC-ISMC 2024 Meeting in Rome.
