Abstract
Objective: To examine the interactions of some 4,5-dihydro-1H-pyrazole derivatives, which are thought to have antiinflammatory effects, with cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, docking studies were carried out on these enzymes.
Material and Method: COX-1 enzyme (3KK6) and COX-2 enzyme (3LN1) were selected from the protein data bank for docking studies. The ligand and protein constructs were prepared using Autodock 1.5.6. AutoDock Vina was used to determining the binding affinity, and Discovery Studio 3.5 was utilised to analyse and display the docking results.
Result and Discussion: As a result of the docking process on COX-1 and COX-2 enzymes, 4,5-Dihydro-1H-pyrazole derivatives were observed to interact with both enzymes. The 4,5-dihydro-1H-pyrazole ring was found to be important in its interactions with the COX-2 enzyme. The inclusion of a bulky group in the construct did not cause any problems in interaction with the COX-1 enzyme but eliminated some interactions with the COX-2 enzyme. To better elucidate the inhibition properties of enzymes, this study should be supported by in vitro and in vivo COX inhibition tests.
