  Synthesis of Novel N-Branched Acyclic Nucleoside Phosphonates As Potent and Selective Inhibitors of Human, Plasmodium falciparum and Plasmodium vivax 6-Oxopurine Phosphoribosyltransferases

  摘要：

  Hypoxanthine-guanine-(xanthine) phosphoribosyltransferase (HG(X)PRT) is crucial for the survival of malarial parasites Plasmodium falciparum (Pf) and Plasmodium vivax (Pv). Acyclic nucleoside phosphonates (ANPs) are inhibitors of HG(X)PRT and arrest the growth of Pf in cell culture. Here, a novel class of ANPs containing trisubstituted nitrogen (aza-ANPs) has been synthesized. These compounds have a wide range of K-i values and selectivity for human HGPRT, PfHGXPRT, and PvHGPRT. The most selective and potent inhibitor of PfHGXPRT is 9-N-(3-methoxy-3-oxopropyl)-N-(2-phosphonoethyl)-2-aminoethyl]hypoxanthine (K-i = 100 nM): no inhibition could be detected against the human enzyme. This compound exhibits the highest ever reported selectivity for PfHGXPRT compared to human HGPRT. For PvHGPRT, 9-[N-(2-carboxyethyl)-N-(2-phosphonoethyl)-2-aminoethyl]guanine has a Ki of SO nM, the best inhibitor discovered for this enzyme to date. Docking of these compounds into the known structures of human HGPRT in complex with ANP-based inhibitors suggests reasons for the variations in affinity, providing insights for the design of antimalarial drug candidates.

  Acyclic nucleoside phosphonates (ANPs) that contain a 6-oxopurine base are good inhibitors of the human and Plasmodium falciparum 6-oxopurine phosphoribosyltransferases (PRTs), key enzymes of the purine salvage pathway. Chemical modifications, based on the crystal structures of several inhibitors in complex with the human PRTase, led to the design of a new class of inhibitors-the aza-ANPs. Because of the negative charges of the phosphonic acid moiety, their ability to cross cell membranes is, however, limited. Thus, phosphoramidate prodrugs of the aza-ANPs were prepared to improve permeability. These prodrugs arrest parasitemia with IC50 values in the micromolar range against Plasmodium falciparum-infected erythrocyte cultures (both chloroquine-sensitive and chloroquine-resistant Pf strains). The prodrugs exhibit low cytotoxicity in several human cell lines. Thus, they fulfill two essential criteria to qualify them as promising antimalarial drug leads. (C) 2015 Elsevier Ltd.
