Pharmacophore modeling and molecular docking led to the discovery of inhibitors of human immunodeficiency virus-1 replication targeting the human cellular aspartic acid-glutamic acid-alanine-aspartic acid box polypeptide 3.
HIV-1 replication has been inhibited by using a compound able to target the human cellular cofactor DEAD-box ATPase DDX3, essential for HIV-1 RNA nuclear export. This compound, identified by means of a computational protocol based on pharmacophoric modeling and molecular docking calculations, represents the first small molecule with such a mechanism of action and could lay the foundations for a pioneering approach for the treatment of HIV-1 infections.
