摘要
A novel cosalane analog having an extended polyanionic pharmacophore was synthesized in order to target specific cationic residues on the surface of CD4. The design rationale is based on a hypothetical binding model of cosalane to the surface of the protein. The new analog displayed an EC50 of 0.55 mu M as an inhibitor of the cytopathic effect of HIV-1(RF) in CEM-SS cells, which represents a significant increase in potency over cosalane itself (EC50 5.1 mu M) Both cosalane and the new analog are inhibitors of viral entry into target cells.
