Design and synthesis of α-carboxy nucleoside phosphonate analogues and evaluation as HIV-1 reverse transcriptase-targeting agents. - The Journal of organic chemistry
The synthesis of the first series of a new class of nucleoside phosphonate analogues is described. Addition of a carboxyl group at the α position of carbocyclic nucleoside phosphonate analogues leads to a novel class of potent HIV reverse transcriptase (RT) inhibitors, α-carboxy nucleoside phosphonates (α-CNPs). Key steps in the synthesis of the compounds are Rh-catalyzed O-H insertion and Pd-catalyzed allylation reactions. In cell-free assays, the final products are markedly inhibitory against HIV RT and do not require phosphorylation to exhibit anti-RT activity, which indicates that the α-carboxyphosphonate function is efficiently recognized by HIV RT as a triphosphate entity, an unprecedented property of nucleoside monophosph(on)ates.
Exploring the role of the α-carboxyphosphonate moiety in the HIV-RT activity of α-carboxy nucleoside phosphonates. - Organic & biomolecular chemistry
As α-carboxy nucleoside phosphonates (α-CNPs) have demonstrated a novel mode of action of HIV-1 reverse transcriptase inhibition, structurally related derivatives were synthesized, namely the malonate , the unsaturated and saturated bisphosphonates and , respectively and the amide . These compounds were evaluated for inhibition of HIV-1 reverse transcriptase in cell-free assays. The importance of the α-carboxy phosphonoacetic acid moiety for achieving reverse transcriptase inhibition, without the need for prior phosphorylation, was confirmed. The malonate derivative was less active by two orders of magnitude than the original α-CNPs, while displaying the same pattern of kinetic behavior; interestingly the activity resides in the "L"-enantiomer of , as seen with the earlier series of α-CNPs. A crystal structure with an RT/DNA complex at 2.95 Å resolution revealed the binding of the "L"-enantiomer of , at the polymerase active site with a weaker metal ion chelation environment compared to (T-α-CNP) which may explain the lower inhibitory activity of .
