Nucleoside reverse transcriptase inhibitors (NRTIs) were the first drugs introduced for the treatment of human immunodeficiency virus-1 (HIV-1) infection. Six NRTIs have been approved for use: zidovudine, stavudine, lamivudine, didanosine, abacavir and zalcitabine. HIV-1 reverse transcriptase (RT) copies the viral RNA genome into the double-stranded DNA required for integration; NRTIs are incorporated into the growing DNA chain and act as chain terminators of this process. Current antiretroviral therapy (ART) for HIV combines one or more NRTIs with a protease inhibitor (PI) and/or a non-nucleoside reverse transcriptase inhibitor (NNRTI), and can achieve high-level suppression of HIV-1 RNA in most HIV-1-infected patients. This has resulted in a dramatic decrease in AIDS mortality.1 Despite successful ART, HIV-1 resistance to NRTIs (as well as to PIs and NNRTIs) can emerge during therapy and result in treatment failure.2 The reasons for this are complex, but fundamentally the RT enzyme of HIV-1 cannot proof-read errors in
