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.
