Abstract
Flexible docking simulations were carried out on a series of isocytosine analogs as xanthine oxidase (XO) inhibitors. This was done by analysing the interaction of these compounds at the active site of XO. The binding free energies of the analogs were calculated using GoldScore. The binding modes of the best-fit conformation were studied, providing some handy important interactions. The results obtained henceforth provided an insight into the pharmacophoric structural requirements for XO inhibition for this class of molecules.
