Although VH1-related member Y (VHY) phosphatase is responsible for the pathogenesis of neuroinflammatory diseases, no small-molecule inhibitor of VHY has been reported so far. Here we first report eight VHY inhibitors identified from molecular docking-based virtual screening and subsequent enzyme inhibition assays. These inhibitors exhibit good biochemical potencies against VHY, with associated IC50 values ranging from 1 to 9 µM. Because all these inhibitors were also screened in silico for having desirable physicochemical properties as a drug candidate, they deserve further investigation by structure-activity relationship studies to develop new medicines for the treatment of neuroinflammatory diseases. The structural features of VHY-inhibitor interactions relevant to the micromolar-level inhibitory activity are addressed in detail.

Computational identification of novel natural inhibitors against triple mutant DNA gyrase A in fluoroquinolone-resistant Typhimurium.

The rising resistance to fluoroquinolones in Typhimurium poses a significant global health challenge. This computational research addresses the pressing need for new therapeutic drugs by utilizing various computational tools to identify potential natural compounds that can inhibit the triple mutant DNA gyrase subunit A enzyme, which is crucial in fluoroquinolone resistance. Initially, the three-dimensional structure of the wild-type DNA gyrase A protein was modeled using homology modeling, and followed by mutagenesis to create the clinically relevant triple mutant (SER83PHE, ASP87GLY, ALA119SER) DNA gyrase A protein structure.

Alzheimer's Disease (AD) is one of the leading neurodegenerative diseases that affect the human population. Several hypotheses are in the pipeline to establish the commencement of this disease; however, the amyloid hypothesis is one of the most widely accepted ones. Amyloid plaques are rich in Amyloid Beta (Aβ) proteins, which are found in the brains of Alzheimer's patients.

Despite significant strides in improving cancer survival rates, the global cancer burden remains substantial, with an anticipated rise in new cases. Immune checkpoints, key regulators of immune responses, play a crucial role in cancer evasion mechanisms. The discovery of immune checkpoint inhibitors (ICIs) targeting PD-1/PD-L1 has revolutionized cancer treatment, with monoclonal antibodies (mAbs) becoming widely prescribed.

The aim was to measure sphenoid sinus volume on the basis of computed tomography data post processing and to investigate the possible relationship with age, gender and mastoid pneumatization. Sphenoid sinus volume was measured using the semi-automatic post processing algorithm of MSCT DICOM datasets of 66 patients. There were 35 female and 31 male subjects.

The main protease (M) is a pivotal target in the life cycle of feline coronavirus (FCoV), which causes a high mortality feline disease, feline infectious peritonitis (FIP). Virtual screening was performed against the feline coronavirus M to find active compounds with low toxicity from a library of natural products. Eighty-six compounds were selected by using the rank of docking score and binding pose analysis.
