  Synthesis and Anti-HIV Activity of Cosalane Analogues with Substituted Benzoic Acid Rings Attached to the Pharmacophore through Methylene and Amide Linkers

  摘要：

  The cosalane pharmacophore has been extended by the attachment of two additional substituted benzoic acid rings through amide and methylene linkers. The resulting compounds display significant antiviral activity when tested in vitro for inhibition of the cytopathic effects of HIV-1(RF) in CEM-SS cells and HIV-1(IIIB) in MT-4 cells. The compound containing the methylene linker also shows moderate activity versus HIV-2(ROD) in MT-4 cells. Because cosalane and related compounds containing extended pharmacophores inhibit the binding of gp120 to CD4, the presently described new compounds are assumed to act by a similar mechanism. A hypothetical model is proposed for the binding of the methylene-linked compound to CD4.

  Design, Synthesis, and Biological Evaluation of Cosalane, a Novel Anti-HIV Agent Which Inhibits Multiple Features of Virus Reproduction

  摘要：

  Cosalane (3), a novel anti-HIV agent having a disalicylmethane unit linked to C-3 of cholestane by a three-carbon Linker, was synthesized from commercially available starting materials by a convergent route. Cosalane proved to be a potent inhibitor of HIV with a broad range of activity against a variety of laboratory, drug-resistant, and clinical HIV-1 isolates, HIV-2, and Rauscher murine leukemia virus. The cytotoxicity of cosalane is relatively low as reflected by an in vitro therapeutic index of > 100. Although cosalane inhibits HIV-1 reverse transcriptase and protease, time of addition experiments indicate that it prevents the cytopathic effect of HIV by acting earlier than reverse transcription in the viral replication cycle. The available evidence indicates that the primary mechanism of action of cosalane involves inhibition of gp120-CD4 binding as well as inhibition of a postattachment event prior to reverse transcription.
