Abstract

Purpose: To develop a potential therapy for rheumatoid arthritis (RA) by altering factors involved in the pathogenesis of the disease.

Methods: Molecular docking simulation-based virtual screening was performed against phosphoinositide-3-kinase gamma (PI3Kg) to identify potential leads that may serve as anti-rheumatoid arthritic agents through their interactions and binding energies with the target receptor, followed by their optimization for improvement of their pharmacokinetics and toxicity profiles.

Results: Molecular docking simulation-based virtual screening and computational toxicity profiling predicted that the lead compounds ZINC04376856, ZINC01729526, ZINC01045089, ZINC03954520, ZINC01738764, and ZINC01163259 were potent PI3Kg inhibitors.

Conclusion: These lead compounds exert potent inhibitory effects on human PI3Kg receptor. Thus, they need to be experimentally validated for use in the development of novel drugs for treating RA in humans.
