  名称：

  Adenosine Analogues as Inhibitors of Trypanosoma brucei Phosphoglycerate Kinase:  Elucidation of a Novel Binding Mode for a 2-Amino-N⁶-Substituted Adenosine

  摘要：

  As part of a project aimed at structure-based design of adenosine analogues as drugs against African trypanosomiasis, N-6-, 2-amino-N-6-, and N-2-substituted adenosine analogues were synthesized and tested to establish structure-activity relationships for inhibiting Trypanosoma brucei glycosomal phosphoglycerate kinase (PGK), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and glycerol-3-phosphate dehydrogenase (GPDH). Evaluation of X-ray structures of parasite PGK, GAPDH, and GPDH complexed with their adenosyl-bearing substrates led us to generate a series of adenosine analogues which would target all three enzymes simultaneously. There was a modest preference by PGK for NG-substituted analogues bearing the 2-amino group. The best compound in this series, 2-amino-N-6-[2 "-(p-hydroxyphenyl)ethyl]adenosine (46b), displayed a 23-fold improvement over adenosine with an IC50 of 130 muM. 2-[[2 "-(p-Hydroxyphenyl)ethyl]amino]adenosine (46c) was a weak inhibitor of T. brucei PGK with an IC50 of 500 muM. To explore the potential of an additive effect that having the N-6 and N-2 substitutions in one molecule might provide, the best ligands from the two series were incorporated into N-6,N-2-disubstituted adenosine analogues to yield N-6-(2 " -phenylethyl)-2-[(2 " -phenylethyl)amino]adenosine (69) as a 30 muM inhibitor of T. brucei PGK which is 100-fold more potent than the adenosine template. In contrast, these series gave no compounds that inhibited parasitic GAPDH or GPDH more than 10-20% when tested at 1.0 mM. A 3.0 Angstrom X-ray structure of a T, brucei PGK/46b complex revealed a binding mode in which the nucleoside analogue was flipped and the ribosyl moiety adopted a syn conformation as compared with the previously determined binding mode of ADP. Molecular docking experiments using QXP and SAS program suites reproduced this "flipped and rotated" binding mode.

  Purine-rich foods have long been suspected as a major cause of hyperuricemia. We hypothesized that inhibition of human concentrative nucleoside transporter 2 (hCNT2) would suppress increases in serum urate levels derived from dietary purines. To test this hypothesis, the development of potent hCNT2 inhibitors was required. By modifying adenosine, an hCNT2 substrate, we successfully identified 8-aminoadenosine derivatives as a new class of hCNT2 inhibitors. Compound 12 moderately inhibited hCNT2 (IC50 = 52 +/- 3.8 mu M), and subsequent structure-activity relationship studies led to the discovery of compound 48 (IC50 = 0.64 +/- 0.19 mu M). Here we describe significant findings about structural requirements of 8-aminoadenosine derivatives for exhibiting potent hCNT2 inhibitory activity.
