The computational chemistry have been focused to pharmacologican and biological systems. Thus, make one to solve and explain several atomic details that for experimental biologicals are very difficult. In this sense, our work-group have tried to use these kind of tools such as docking, molecular dynamic simulations and quamtum chemistry.
