Article Abstract
Aim: Rescoring of docking-binding poses can significantly improve molecular docking results. Our aim was to evaluate postprocessing docking protocols in order to determine the most suitable methodology for the study of the binding of congeneric compounds to protein kinases.
Materials & Methods: Diverse ligand-receptor poses generated after docking were submitted to different relaxation protocols. The Molecular Mechanics Poisson-Boltzmann (Generalized Born) Surface Area approach was applied for the evaluation of the binding affinity of complexes obtained. The performance of various Molecular Mechanics Poisson-Boltzmann (Generalized Born) Surface Area methodologies was compared.
Results: The inclusion of a postprocessing protocol after docking enhances the quality of the results, although the best methodology is system dependent.
Conclusion: An examination of the interactions established has allowed us to suggest useful modifications for the design of new type II inhibitors.

ROSAH (retinal dystrophy, optic nerve edema, splenomegaly, anhidrosis, and headache) syndrome is a rare genetic disease caused by variants in alpha-kinase 1 (ALPK1) resulting in downstream pro-inflammatory signaling mediated by the TIFA/TRAF6/NF-κB pathway. Here, we report the design of an ALPK1 inhibitor, DF-003, with pharmacokinetic properties suitable for daily oral dosing. In biochemical assays, DF-003 potently inhibits human ALPK1 (IC = 1.

Type 2 diabetes (T2D) is characterized by persistent and unresolved tissue inflammation caused by the infiltration and dysregulation of immune cells. Current therapeutics targeting inflammatory immune cells for T2D remain limited. In this study, we analyzed single cell RNA from metabolic organs in T2D, revealing increased macrophage accumulation and a pathogenic macrophage subpopulation defined as NOD-like receptor (NLR) family pyrin domain-containing 3 (NLRP3) inflammatory and metabolically activated macrophages.

Cell motility is fundamental to eukaryotic life. Two main modalities exist in animal cells: swimming (via flagellar beating) and crawling (via actin-powered deformations of the cell body). Swimming and crawling are present across opisthokonts, including in choanoflagellates, the sister group of animals.

The myristoylated preS1 domain (myr-preS1) of the hepatitis B virus (HBV) large surface protein is essential for binding to the receptor protein, Na/taurocholate co-transporting polypeptide (NTCP), and for the subsequent internalization of the virus-receptor complex. NTCP, which is expressed in hepatocytes, plays a physiological role in hepatic bile acid transport. Recent cryo-electron microscopy structures of the myr-preS1-NTCP complex were used to analyze virus-receptor interactions at the molecular level.
