  importance in oncology, this protein has become a popular target for drug discovery, efforts which have as yet brought little success. This study demonstrates that adenosine-derived HSP70 inhibitors potentially bind to the protein with a novel mechanism of action, the stabilization by desolvation of an intramolecular salt-bridge which induces a conformational change in the protein, leading to high affinity

  HSP70 是一种分子伴侣，是热休克反应的关键组成部分。由于其在肿瘤学中的重要性，这种蛋白质已成为药物发现的热门目标，但这些努力尚未取得成功。该研究表明，腺苷衍生的 HSP70 抑制剂可能以一种新的作用机制与蛋白质结合，通过分子内盐桥的去溶剂化来稳定化，从而诱导蛋白质的构象变化，从而产生高亲和力配体。我们还证明，通过这种机制的应用，可以以合理的方式优化腺苷衍生的 HSP70 抑制剂。

  To achieve a systematic synthesis of purine 8,5'-imino and substituted imino cyclonucleosides, 2',3'-O-isopropylidene-purinenucleosides substituted with a methylamino (4a,b), benzyl-amino (4c,d,g and h) and allylamino group (4e,f,i and j) at the C8 were synthesized. With these substrates in hand, extensive 8,5'-cyclization reactions were carried out using diphenyl carbonate/Et3N (Method A), N,N'-carbonyldiimidazole

• Synthesis of Some 1-Methyladenine Analogs and Their Biological Activities on Starfish Oocyte Maturation

  Starfish oocytes are naturally arrested at the prophase stage of the first meiotic division and resume meiosis in response to the maturation-inducing hormone 1-methyladenine. Five analogs of 1-methyladenine including three novel ones were synthesized and tested for biological activities as 1-methyladenine agonists or antagonists in triggering reinitiation of meiosis of starfish Asterina pectinifera oocytes, as well as for competition in binding to putative 1-methyladenine receptors with respect to 1-methyladenine. 1-Ethyladenine was an effective agonist, but 1-propyladenine served as a weak antagonist to 1-methyladenine, indicating strict specificity for a relatively small N-1 substituent. Analogs in which carboxymethyl or methyl group substitutes for a hydrogen of 6-amino group still retained oocyte maturation-inducing activity, but to a much lesser degree. The results of the competitive binding assay with cortices of oocytes demonstrated that these agonists or antagonist inhibited the binding of [3H]1-methyladenine to receptors. 8-methylamino-1-methyladenine competed only weakly with [3H]1-methyladenine for the binding to cortices, although it behaved as a potent antagonist.

• New Insights into the Design of Inhibitors of Human <i>S</i>-Adenosylmethionine Decarboxylase: Studies of Adenine C⁸ Substitution in Structural Analogues of <i>S</i>-Adenosylmethionine

  S-adenosylmethionine decarboxylase (AdoMetDC) is a critical enzyme in the polyamine biosynthetic pathway and depends on a pyruvoyl group for the decarboxylation process. The crystal structures of the enzyme with various inhibitors at the active site have shown that the adenine base of the ligands adopts an unusual syn conformation when bound to the enzyme. To determine whether compounds that favor the syn conformation in solution would be more potent AdoMetDC inhibitors, several series of AdoMet substrate analogues with a variety of substituents at the 8-position of adenine were synthesized and analyzed for their ability to inhibit hAdoMetDC. The biochemical analysis indicated that an 8-methyl substituent resulted in more potent inhibitors, yet most other 8-substitutions provided no benefit over the parent compound. To understand these results, we used computational modeling and X-ray crystallography to study C(8)-substituted adenine analogues bound in the active site.

  ecto-5'-Nucleotidase (eN, CD73) catalyzes the hydrolysis of extracellular AMP to adenosine. eN inhibitors have potential for use as cancer therapeutics. The eN inhibitor alpha,beta-methylene-ADP (AOPCP, adenosine-5'-O-[(phosphonomethyl)phosphonic acid]) was used as a lead structure, and derivatives modified in various positions were prepared. Products were tested at rat recombinant eN. 6-(Ar)alkylamino substitution led to the largest improvement in potency. N-6-Monosubstitution was superior to symmetrical N-6,N-6-disubstitution. The most potent inhibitors were N-6-(4chlorobenzyl)-(10l, PSB-12441, K-i 7.23 n.M), N-6-phenylethyl(10h, PSB-12425, K-i 8.04 nM), and N-6-benzyl-adenosine-5'-O[(phosphonomethyl)phosphonic acid] (10g, PSB-12379, K-i 9.03 nM). Replacement of the 6-NH group in 10g by 0 (10q, PSB-12431) or S (10r, PSB-12553) yielded equally potent inhibitors (10q, 9.20 nM; 10r, 9.50 aM). Selected compounds investigated at the human enzyme did not show species differences; they displayed high selectivity versus other ecto-nudeotidases and ADP-activated P2Y receptors. Moreover, high metabolic stability was observed. These compounds represent the most potent eN inhibitors described to date.
