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 [...]

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.

Context. Lenrispodun (Intra-Cellular Therapies) is a phosphodiesterase (PDE) type 1 (PDE1) inhibitor being developed for CNS and non-CNS disorders, including heart failure, and cancer. Studies to identify PDE inhibitors date back at least 30 years, and at least 10 drugs have been approved targeting other PDE proteins (spearheaded by the PDE5 [...]

Bexotegrast is a dual-selective αvβ6-αvβ1 integrin inhibitor with surprising efficacy and safety data from a Ph. II trial in idiopathic pulmonary fibrosis (IPF). The αv integrins have been studied for decades in indications such as cancer and IPF. Both small molecule and antibody-based integrin inhibitors have demonstrated preclinical toxicities in non-human primates. This article highlights the unmet need for effective therapies for IPF and related conditions, a comparison of bexotegrast with other integrin binders, and possible reasons why bexotegrast is different in terms of safety.

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 [...]
