TRPV1 are ion channels capable of sensing different stimuli, integrating and translating them into signal language. TRPV1 antagonists have attracted much attention for the treatment of various diseases related to the management of pain physiology and neurogenic inflammation, such as anti-inflammatory, antineoplastic, and anti-nociceptive effects. Here, we performed a 3D-QSAR, molecular docking, and MD simulations on a novel series of indole triazole derivatives as antagonists of TRPV1. The aim was to design novel potent TRPV1 antagonists with strong inhibitory activity. The significant 3D-QSAR models showed a good correlation between experimental and predicted activity. CoMSIA was used to construct the best 3D QSAR model using the PLS method showing correlative and predictive ability (R2=0.985. Q2=0.788. SEE=0.105). Electrostatic, steric, and hydrophobic fields play an important role in the variation of biological activity. Molecular Docking analysis was used to validate the 3D-QSAR methods and to explain the binding site and interactions between the ligands and the receptor. Based on these results, a novel series of compounds were predicted. The pharmacokinetic properties of predicted compounds were analyzed by drug-likeness and ADMET prediction. The best-docked compounds were subjected to MD simulation to affirm the final candidate molecules' conformational to confirm their dynamic behavior and stability.
