Computer-aided molecular design of novel glucosidase inhibitors for AIDS treatment.

Abstract Since the onset of the AIDS epidemic, some 20 million people have died and the estimate is that today close to 40 million are living with type 1 human immunodeficiency virus (HIV)/AIDS. About 14 thousands people are infected worldwide daily with this disease. Still, only a few pharmaceuticals are available for AIDS chemotheraphy. Some pharmaceuticals act against the virus before the entrance of the HIV into the host cells. One of these targets is the glucosidase protein. This class of enzymes has been recently explored because the synthesis of viral glycoproteins depends on the activity of enzymes, such as glucosidase and transferase, for the elaboration of the polysaccharides. In this work we study several glucosidase inhibitors. The DFT method is used to compute atomic charges and the lig-and/receptor interaction was simulated with docking software. Analysis of the interactions of the proposed pharmaceutical, apseudodisaccharide, with the Thermotoga maritima 4-alpha glucanotransferase in comple...
