  摘要：

  使用一套自主研发的自动化合成系统，制备了72个四肽衍生物库，这些是用于合成具有药物吸引力的五肽的起始材料，采用了一种汇聚策略。首先，利用自动化合成工作站大规模（100-1000克）合成了18种二肽，然后使用自动化系统在中等规模（5-10克）合成了72种四肽。每个二肽或四肽均在单个操作周期中使用改良的甲磺酸方法制备，随后在小型规模（100毫克-1克）下利用机器人工作站并行合成了56种五肽的子库。

  To find novel nano-materials with anti-osteoporosis activity and without side effects three novel anti-osteoporosis active amphiphiles, 17β-(RGD-AA-amido)-11α-hydroxyandrost-1,4-diene-3-one (5a: AA = Ser, 5b: AA = Val, 5c: AA = Phe), were constructed by coupling the bone resorption inhibiting active RGD-peptides and anti-osteoporosis active 17β-amino-11α-hydroxyandrost-1,4-diene-3-one. In the solid state 5a, 5b and 5c exist as dispersed globes of 300 nm–14 μm in diameter, dispersed eggs of 110 nm–19 μm in diameter and beads of 238 nm–22 μm in diameter, respectively. In ultrapure water 1.1 μM of 5a, 5b and 5c form nano-globes of 33–400 nm, 16–278 nm and 54–187 nm in diameter, respectively. At an oral dose of 110 nmol kg−15a–c effectively inhibited mice from developing osteoporosis. In contrast to estradiol, 5a–c did not induce mice to develop endometrial hyperplasia and thrombus.

  为了寻找具有抗骨质疏松活性且无副作用的新型纳米材料，通过结合抑制骨吸收活性的RGD多肽和具有抗骨质疏松活性的17β-氨基-11α-羟基雄甾-1,4-二烯-3-酮，构建了三种新型抗骨质疏松活性的两亲性分子，17β-(RGD-AA-酰胺)-11α-羟基雄甾-1,4-二烯-3-酮（5a：AA = Ser，5b：AA = Val，5c：AA = Phe）。在固态下，5a，5b和5c分别以直径为300 nm至14 μm的分散球体、直径为110 nm至19 μm的分散蛋和直径为238 nm至22 μm的珠子存在。在超纯水中，1.1 μM的5a，5b和5c分别形成直径为33至400 nm、16至278 nm和54至187 nm的纳米球体。在口服剂量为110 nmol kg-1时，5a至5c有效地抑制了小鼠的骨质疏松发展。与雌二醇相比，5a至5c不会导致小鼠子宫内膜增生和血栓形成。

  A solution-phase synthesis of an alpha-ketothiazole library of the general form D-Phe-L-AA-Arg-alpha-ketothiazole is described. The five-step synthesis is accomplished using a combination of polymeric reagents and polymer-assisted solution-phase purification concepts, including reactant-sequestering resins, reagent-sequestering resins, and tagged reagents. The multistep synthesis affords desired alpha-ketothiazole products in excellent purities and yields. A variety of L-amino acid inputs were used to probe the S-2 pocket of tissue Factor VIIa enzyme to influence both potency and selectivity. An X-ray crystal structure of compound 10k bound to the TF/ VIIa complex was obtained that explains the observed selectivity. The alpha-ketothiazoles were found to be potent, reversible-covalent inhibitors of tissue Factor VIIa, with some analogues demonstrating selectivity over thrombin.
• (3S)-N-(l-Aminoacyl)-1,2,3,4-tetrahydroisoquinolines, a class of novel antithrombotic agents: Synthesis, bioassay, 3D QSAR, and ADME analysis

  To increase antithrombotic activity, 3S-tetrahydroisoquinoline-3-carboxylic acid (1) was modified with natural amino acids to form 19 novel dipeptide analogs, 3S-tetrahydroisoquinoline-3-carboxyamino acids (5a-s), targeting the intestinal peptide transport system. In vitro assay of 5a-s indicated that their potencies for inhibiting adenosine diphosphate (ADP), arachidonic acid (AA), platelet-activating factor (PAF), and thrombin (TH)-induced platelet aggregations were higher than that of 1. Additionally, in vivo assay of 5a-s indicated that their potencies for inhibiting thrombogenesis in rats were also higher than that of 1. Among the candidates, 5h with Ser attachment showed the most impressive features for further development. According to molecular field analysis based Cerius(2) QSAR module, two equations (r, 0.961 and 0.988) correlating the structures with both in vitro and in vivo activities of 5a-s were established. ADMET calculations predict higher intestinal absorption for compounds 5a-s. Further investigation with 5h as a lead compound is underway. (C) 2008 Elsevier Ltd. All rights reserved.
• Tripeptide Probes for Tripeptidyl Protease I Production via Gene Transfer

  Tripeptides derived from 5-chloroanthraquinone hydrazide and anthraquinone hydrazide have been prepared as potential reagents to probe cellular expression of tripeptidyl protease I (TPP-I). Attempted chemical synthesis of Gly-L-Pro-L-Ala-chloroanthraquinone hydrazide, a compound that had been reported to serve as a substrate for this enzyme, was complicated by formation of a pyrazoloquinone. In contrast, formation of pyrazoloquinones was not observed during coupling reactions with anthraquinone hydrazide, and several tripeptide derivatives of this compound were prepared. The most attractive probe for TPP-I activity in tests with mouse kidney tissue sections proved to be Gly-L-Pro-L-Ser anthraquinone hydrazide.
