Medicinal and toxicological investigation of some common NSAIDs; A computer-aided drug design approach

Abstract

Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used for the treatment of pain, fever, and inflammation. Their consumption rises some crucial side effects like gastrointestinal, cardiovascular, and renal injury because of the non-selective reduction of prostaglandin synthesis, with differences in the extent of inhibition of the cyclooxygenase. Attempts have been taken for a comparative biochemical, medicinal, and toxicological investigation to raise awareness of the consumption of NSAIDs. In-silico methods were incorporated to investigate their physicochemical, spectral, medicinal, pharmacological, and toxicological properties. Molecular docking and non-bonding calculations were performed against the human prostaglandin synthase protein to reveal their binding affinity and interactions with the amino acid residues of the receptor protein. Further, molecular dynamics simulation was conducted to validate the binding mode and drug-protein stability at the inhibiting binding pocket. The physical and chemical analysis supports their geometries and spectral results confirming the presence of essential functional groups at the core structure. From ADMET and PASS prediction, all the drugs are non-carcinogenic (except IBP), and nonselective NSAIDs showed relatively higher adverse effects compared to selective agents. Based on the above studies, this report can be helpful to understand more deeply the medicinal, and toxicological effects of the reported NSAIDs.
