  一类新的取代嘌呤与Gly-AA-OBzl的偶联物：口服镇痛活性的合成和评价

  摘要：

  针对慢性疼痛的化学疗法，通过五步反应方法和19种新型缀合物N- [2-氯-9-（四氢吡喃-2-）偶联了两种止痛药，取代的嘌呤和Gly-AA-OBzl。提供了（yl）-9 H-嘌呤-6-yl] -N-环丙基糖基氨基酸苄酯。在鼠尾轻弹模型上，测定了它们的体内止痛活性。结果表明，将Gly-OC 2 H 5引入取代的嘌呤的6-位导致镇痛活性的模棱两可的增加，而将Gly-AA-OBzl引入该位置导致镇痛活性的显着增加。

  In order to confirm the primary structure of a delicious peptide which was isolated from extracts of the beef meat, a peptide, H-Lys-Gly-Asp-Glu-Glu-Ser-Leu-Ala-OH, was synthetized. Both of the synthetized peptide and isolated one were identical as shown in many respects.

  development of nonspecific airway hyperresponsiveness to carbachol. These results show that highly selective and potent small-molecule antagonists can be identified to integrins with primary specificity for peptide domains other than Arg-Gly-Asp (RGD); they confirm the generality of integrins as small molecule targets; and they validate alpha4beta1 as a therapeutic target for asthma.

  整联蛋白α4beta1介导白细胞募集，激活，介质释放和凋亡抑制，并且它在炎症病理生理学中发挥着核心作用。描述了基于来自细胞纤连蛋白交替剪接的连接段1（CS-1）肽的Leu-Asp-Val（LDV）序列的高亲和力，选择性的alpha4beta1抑制剂，该抑制剂采用了新型N端肽“上限”策略。一种抑制剂BIO-1211的效价比起始肽高约10（6）倍，并表现出紧密结合的特性（koff = 1.4 x 10（-4）s-1，KD = 70 pM），这是一个了不起的发现用于蛋白质受体的非共价小分子抑制剂。BIO-1211对激活形式的alpha4beta1也具有200倍的选择性，并且它刺激整联蛋白beta1亚基上配体诱导的表位的表达，与受体的配体结合位点的占有率一致的性质。用3毫克雾化剂量的BIO-1211预处理过敏羊可抑制抗原攻击后的早期和晚期气道反应，并防止非特异性气道对卡巴胆碱的过度反应。这些结果表

  New multi-valent, carbohydrate ligands that contain terminal N-acetylgalactosamine (GalNAc) or lactose (Lac) were prepared using a nitrilotriacetic acid (NTA) derivative of L-lysine as scaffold. Tri-valent structures were prepared by attaching an x-amino glycoside of GalNAc or Lac to each of the three carboxyl groups of N-epsilon-protected N-alpha-dicarboxymethyl-L-lysine. In addition, a hexa-valent lactoside was synthesized by attaching N-epsilon-deprotected trivalent lactoside to each of the carboxyl group of N-alpha-(trifluoroacetamido) hexanoyl L-aspartic acid. Tri-valent GalNAc glycosides and the hexa-valent lactoside had high affinity (dissociation constants approaching nM) for rat hepatocytes. The hexa-valent lactoside, after de-Ne-protection, was modified with a chelator, diethylenetriaminepentaacetic acid (DTPA), through which a fluorescent or radioactive tag, such as europium or indium, can be firmly attached. Intravenous infusion of (111)Indium-tagged hexa-valent lactoside to rats and mice resulted in nearly exclusive accumulation of radioactivity in the liver.(C) 2011 Elsevier Ltd. All rights reserved.

  five-step-reaction procedure and 19 novel conjugates N-[2-chloro-9-(tetrahydropyran-2-yl)-9H-purin-6-yl]-N-cyclopropylglycylamino acid benzylesters were provided. On mouse-tail flick model their in vivo analgesic activities were assayed. The results indicate that introducing Gly-OC2H5 into the 6-position of the substituted purine leads to ambiguous increase of the analgesic activity, while introducing Gly-AA-OBzl
