From: In situ click chemistry generation of cyclooxygenase-2 inhibitors

Computational analysis of click chemistry building blocks in the COX-2 active site. Molecular docking of 5-azido-pyrazole compounds (5, 14, 27, and 31) and alkynes (6a–6f and 15a–15e) in the binding site of COX-2 isozyme (PDB ID: 6COX). Hydrogen atoms of amino-acid residues are omitted for clarity
