A diphosphate of a novel cyclopentyl based nucleoside phosphonate with potent inhibition of HIV reverse transcriptase (RT) (20, IC(50) = 0.13 mu M) has been discovered. In cell culture the parent phosphonate diacid 9 demonstrated antiviral activity EC(50) = 16 mu M, within two-fold of GS-9148, a prodrug of which is currently under clinical investigation, and within 5-fold of tenofovir (PMPA). In vitro cellular metabolism studies using 9 confirmed that the active diphosphate metabolite is produced albeit at a lower efficiency relative to GS-9148. (C) 2009 Elsevier Ltd. All rights reserved.
