Background: The thromboxane A2 receptor (TPαR) plays an important role in the amplification of platelet responses during thrombosis. Receptor activity is regulated by internalization and receptor desensitization. The mechanism by which constitutive surface expression of the TPαR is regulated is unknown.

COX-2 Inhibitor Prediction With KNIME: A Codeless Automated Machine Learning-Based Virtual Screening Workflow.

J Comput Chem

January 2025

Pharmaceutical Chemistry Research Laboratory 1, Department of Pharmaceutical Engineering & Technology, Indian Institute of Technology (Banaras Hindu University), Varanasi, India.

Cyclooxygenase-2 (COX-2) is an enzyme that plays a crucial role in inflammation by converting arachidonic acid into prostaglandins. The overexpression of enzyme is associated with conditions such as cancer, arthritis, and Alzheimer's disease (AD), where it contributes to neuroinflammation. In silico virtual screening is pivotal in early-stage drug discovery; however, the absence of coding or machine learning expertise can impede the development of reliable computational models capable of accurately predicting inhibitor compounds based on their chemical structure.

The urothelium and lamina propria (LP) contribute to sensations of bladder fullness by releasing multiple mediators, including prostaglandins (PGs) and adenosine 5'-triphosphate (ATP), that activate or modulate functions of cells throughout the bladder wall. Mediators that are simultaneously released in response to bladder distention likely influence each other's mechanisms of release and action. This study investigated whether PGs could alter the extracellular hydrolysis of ATP by soluble nucleotidases (s-NTDs) released in the LP of nondistended or distended bladders.

Farnesoid X receptor (FXR), a nuclear receptor, is expressed in calvaria and bone marrow stromal cells and plays a role in bone homeostasis. However, the mechanism of FXR-activated osteoblast differentiation remains unclear. In this study, we investigated the regulatory mechanism underlying FXR-activated osteoblast differentiation using bone morphogenetic protein-2 (BMP-2)-induced mouse ST-2 mesenchymal stem cells.
