Summary

Isoselective inhibitors, designed with specific chemical sites (CS) and recognition sites (RS), show binding affinity trends primarily dictated by their CS fragments. This finding aids in designing new enzyme inhibitors and virtual screening.

  • Synthesis and analysis of isoselective inhibitors with varying CS fragments.

    • Main Results:

    • Binding affinity trends in isoselective inhibitors are predominantly determined by their chemical site (CS) fragments.
    • Isoselective inhibitors exhibit consistent affinity trends across related enzymes.
    • Excellent correlation was observed between experimental and theoretical Ki values.

    Conclusions:

    • The chemical site (CS) is the primary determinant of binding affinity for isoselective inhibitors.
    • The described method serves as a valuable tool for virtual screening and enzyme inhibitor design.
    • This research facilitates the development of targeted enzyme inhibitors for various therapeutic applications.
