Three novel 4-subsituted-7-(2'-deoxy-2'-fluoro-4'-azido-beta-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-beta-D-ribofuranosyl)pyrrolo[2,3-d]pyrimidine 10 exhibited the most potent anti-HIV-1 activity (EC50 = 0.5 +/- 0.3 mu M), while 4-hydroxy-7-(2'-deoxy-2'-fluoro-4'-azido-beta-D-ribofuranosyl)pyrrolo[ 2,3-d]pyrimidine 9 and 4-amino-5-fluoro-7-(2'-deoxy-2'-fluoro-4'-azido-beta-D-ribofuranosyl)pyrrolo[2,3-d]pyrimidine 11 showed moderate activity (EC50 = 13 +/- 8 and 5.4 +/- 0.3 mu M, 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 mu M. (C) 2011 Elsevier Ltd.
