 AB    HIV-1 protease has been identified as a significant target enzyme in
       AIDS research. While numerous peptide-derived inhibitors have been
       described, the identification of a nonpeptide inhibitor remains an
       important goal. Using an HIV-1 protease mass screening technique,
       4-hydroxy-3-(3-phenoxypropyl)-2H-1-benzopyran-2-one (1) was identified
       as a nonpeptide competitive inhibitor of the enzyme. Employing a Monte
       Carlo-based docking procedure, the coumarin was docked in the active
       site of the enzyme, revealing a binding mode that was later confirmed by
       the X-ray crystal analysis. Several analogs were prepared to test the
       binding interactions and improve the overall binding affinity. The most
       active compound in the study was
       4,7-dihydroxy-3-[4-(2-methoxyphenyl)butyl]-2H-1-benzopyran-2-one (31).
