Аннотация
Carbonic anhydrase (CA) IX is a very interesting subject for study due to its overexpression in cancer and its expression in very few normal tissues. There are not yet experimental 3D structures of the catalytic domain of this isozyme, and only a few computational studies have been reported. A homology model of CA IX was developed, and using Gold software 124 CA IX inhibitors were docked. The best poses of the ligands were then used as an alignment tool for the development of the first reported CA IX 3D-QSAR model. The obtained results confirm the reliability of the constructed CA IX model and the proposed computational strategy for investigating CAs.
