 AB    Over 25 selected naphthalenesulfonic acid derivatives were evaluated for
       their inhibitory effect on two different functional domains of the HIV-1
       reverse transcriptase (RT), namely the ribonuclease H and DNA polymerase
       activities. Most of the analogues were found to be either specific
       toward the DNA polymerase activity or showed nonselective inhibition of
       both catalytic functions. The most active compounds are either
       symmetrical derivatives or nonsymmetrical derivatives containing a
       lipophilic appendage consisting of a palmitoyl or cholesteryl moiety.
       The six most active compounds in the preliminary screen, derivatives 6,
       16, 17, 23, 26, and 27, were subjected to experiments to determine their
       50% inhibitory concentration (IC50) values in the assays that measure
       RNA-dependent DNA polymerase (RDDP), DNA-dependent DNA polymerase
       (DDDP), and ribonuclease H (RNase H) functions of HIV-1 RT. The most
       potent derivative was a nonsymmetric cholesterol-linked
       4-amino-5-hydroxy-2,7-naphthalenedisulfonic acid analogue, compound 23,
       which demonstrated an IC50 value of 0.06 microM for inhibiting RDDP
       activity. Inhibition of DDDP and RNase H activity for this compound was
       demonstrated at concentrations that were over 100-fold of that for
       inhibiting RDDP activity. However, the potency of this active compound
       does not correlate in the whole virus assay, probably due to a lack of
       cellular entry. The cholesterol derivative, 23, also possesses HIV-1
       protease inhibitory activity and belongs to a unique class of
       multifunctional HIV-1 inhibitors.
