Evolution of Free-Energy Calculations for Drug Discovery

Christopher Ingold Building, XLG1 Lecture Theatre

William L. Jorgensen, Yale University

Free-energy calculations have had a revolutionary effect on computational chemistry. In conjunction with molecular dynamics and Monte Carlo simulations, they have enabled the calculation of free energy changes for wide-ranging phenomena including fundamental solution thermodynamics, activation barriers for reactions in solution, host-guest binding, and drug lead optimization. An overview of our FEP efforts beginning with the ethane to methanol calculation in 1985 and leading to recent discoveries of extraordinarily potent inhibitors of the main protease of SARS-CoV-2 will be presented.
