Özet

Cyclooxygenase-2 (COX-2) inhibitors are nonsteroidal anti-inflammatory drugs that treat inflammation, pain and fever. This study determined the interaction mechanisms of COX-2 inhibitors and the molecular properties needed to design new drug candidates. Using machine learning and explainable AI methods, the inhibition activity of 1488 molecules was modelled, and essential properties were identified. These properties included aromatic rings, nitrogen-containing functional groups and aliphatic hydrocarbons. They affected the water solubility, hydrophobicity and binding affinity of COX-2 inhibitors. The binding mode, stability and ADME properties of 16 ligands bound to the Cyclooxygenase active site of COX-2 were investigated by molecular docking, molecular dynamics simulation and MM-GBSA analysis. The results showed that ligand 339,222 was the most stable and effective COX-2 inhibitor. It inhibited prostaglandin synthesis by disrupting the protein conformation of COX-2. It had good ADME properties and high clinical potential. This study demonstrated the potential of machine learning and bioinformatics methods in discovering COX-2 inhibitors. Graphical abstract: This study uses machine learning, bioinformatics and explainable artificial intelligence (XAI) methods to discover and design new drugs that can reduce inflammation by inhibiting COX-2. The activity and properties of various molecules are modelled and analysed. The best molecule is selected, and its interaction with the enzyme is investigated. The results show how this molecule can block the enzyme and prevent inflammation. XAI methods are used to explain the molecular features and mechanisms involved. (Figure presented.)
