We have presented a perspective of progress in three areas of simulations of complex molecules: the development of force fields for molecular simulation; the application of computer graphics, molecular mechanics and molecular dynamics in simulations of DNA and DNA-drug complexes and the application of computer graphics, molecular mechanics and quantum mechanics in studies of enzyme substrate interactions. It is our perspective that improvements are being made in force fields, and these will allow a more accurate simulation of structures and energies of complex molecules. In the area of DNA molecular mechanics and dynamics, it is clear that the use of computer graphics model building combined with NMR NOE data is a potentially very powerful tool in accurately determining structures of drug-DNA complexes using molecular mechanics and dynamics. Finally, we are in a position to reasonably simulate structures and (qualitatively) energies for complete reaction pathways of enzymes using a combination of computer graphics, molecular mechanics and quantum mechanics. More accurate energies and pathways are sure to follow, using the combined molecular mechanics/quantum mechanics optimization developed by Singh and the free energy perturbation methods pioneered in Groningen and Houston.
