 AB    We have observed a high correlation between the intermolecular
       interaction energy (Einter) calculated for HIV-1 protease inhibitor
       complexes and the observed in vitro enzyme inhibition. A training set of
       33 inhibitors containing modifications in the P1' and P2' positions was
       used to develop a regression equation which relates Einter and pIC50.
       This correlation was subsequently employed to successfully predict the
       activity of proposed HIV-1 protease inhibitors in advance of synthesis
       in a structure-based design program. This included a precursor, 47, to
       the current phase II clinical candidate, L-735,524 (51). The development
       of the correlation, its applications, and its limitations are discussed,
       and the force field (MM2X) and host molecular mechanics program
       (OPTIMOL) used in this work are described.
