Three novel 4-subsituted-7-(2'-deoxy-2'-fluoro-4'-azido-β-D-ribofuranosyl)pyrrolo[2,3-d]pyrimidine analogues were designed, synthesized, and tested for their anti-HIV-1 activity. Initial biological studies indicated that among these pyrrolo[2,3-d]pyrimidine ribonucleoside analogues, 4-amino-7-(2'-deoxy-2'-fluoro-4'-azido-β-D-ribofuranosyl)pyrrolo[2,3-d]pyrimidine 10 exhibited the most potent anti-HIV-1 activity (EC(50)=0.5±0.3 μM), while 4-hydroxy-7-(2'-deoxy-2'-fluoro-4'-azido-β-D-ribofuranosyl)pyrrolo[2,3-d] pyrimidine 9 and 4-amino-5-fluoro-7-(2'-deoxy-2'-fluoro-4'-azido-β-D-ribofuranosyl)pyrrolo[2,3-d] pyrimidine 11 showed moderate activity (EC(50)=13±8 and 5.4±0.3 μM, respectively). The cytotoxicity of these compounds has also been assessed. No significant cytotoxicities were found for any of these compounds with concentrations up to 25 μM.
