Acyclic glycosidopyrroles of type 1, synthesized in good overall yields, were evaluated for anti-viral activity. Compound 10i was found to inhibit the HIV-1 replication at concentrations that were very close to those cytotoxic for MT-4 cells. Compounds 10a,f,i inhibited both strains HSV-1 and HSV-2 at concentrations slightly below those cytotoxic for Vero cells. However for this series of glycosidopyrroles some relationship between calculated log P values and the observed cytotoxicity was found.
