Abstract: New polyanionic compounds were obtained from radical addition of thiomalic acid and mercaptopropionic acid onto perallylated cyclodextrins (CDs) under UV irradiation with a catalytic amount of alpha,alpha'-azobis(isobutyronitrile). All these polyanions, bearing 18-48 carboxylate groups, inhibited human immunodeficiency virus type 1 (HIV-1) strain IIIB replication in MT-4 cells at a 50% inhibitory concentration (IC50) of 0.1-2.9 microM, while not being toxic to the host cells at concentrations up to 62 microM. These compounds were also active against a clinical HIV-1 isolate (HE) at >/=4-fold higher concentrations. Only some compounds showed activity against the two HIV-2 strains (ROD and EHO) but at higher concentrations than those required to inhibit HIV-1 (IIIB and HE) replication. In addition, these compounds were not active against the M-tropic HIV-1 strain BaL but were active against simian immunodeficiency virus [SIV (MAC251)]. These compounds were also inhibitory to the replication of human cytomegalovirus at an IC50 of 1-10 microM, but not herpes simplex virus (type 1 and type 2) or other (picorna-, toga-, reo-, orthomyxo-, paramyxo-, bunya-, rhabdo-, and poxvirus) viruses. Radical addition on perallylated CDs of a protected cysteine gave polyzwitterionic compounds. None of these last compounds proved inhibitory to the replication of HIV-1, HIV-2, or any of the other viruses tested.
