HIV-1 reverse transcriptase (RT) plays a central role in the viral life cycle, and roughly half of the FDA-approved anti-HIV drugs are targeting RT. Nucleoside analogs (NRTIs) require cellular phosphorylation for binding to RT, and to bypass this rate-limiting path, we designed a new series of acyclic nucleoside phosphonate analogs as nucleoside triphosphate mimics, aiming at the chelation of the catalytic Mg 2+ ions via a phosphonate and/or a carboxylic acid group. Novel synthetic procedures were developed to access these nucleoside phosphonate analogs. X-ray structures in complex with HIV-1 RT/dsDNA demonstrated that their binding modes are distinct from that of our previously reported compound series. The impact of chain length, chirality and linker atom have been discussed. The detailed structural understanding of these new compounds provides opportunities for designing new class of HIV-1 RT inhibitors.
