Abstract Background Heterosexual intercourse remains the major route of HIV-1 transmission worldwide with almost 5 million new infections occurring each year. Women increasingly bear a disproportionate burden of the pandemic thus there is an urgent need to develop new strategies to reduce HIV-1 transmission that could be controlled by women themselves. The potential of topical microbicides to reduce HIV transmission across mucosal surfaces has been clearly identified and some agents are currently under evaluation in clinical trials. Many of these first generation microbicides consist of polyanionic compounds designed to interfere with viral attachment. Here we have evaluated two candidate polyanion compounds in clinical trials PRO 2000 and dextrin sulphate DxS to determine their safety and efficacy against in vitro HIV-1 and HSV-2 infection using .
