  摘要：

  5-Azido-2,5-dideoxy-beta-D-erythro-pentofuranosyl nucleosides 10 and their corresponding alpha-anomers 11 have been synthesized by condensation of methyl 3-O-acetyl-5-azido-2,5-dideoxy-beta-D-erythro-pentofuranoside (7) with silylated nucleobases followed by deprotection with methanolic ammonia. Reaction of silylated thymine (19) with methyl 2,3-di-O-benzoyl-5-deoxy-5-fluoro-D-arabino-pentofuranoside (15) and methyl 5-azido-2,3-di-O-benzoyl-5-deoxy-alpha-D-arabino-pentofuranoside (17alpha) afforded a mixture of the alpha-nucleosides 20 and the acyclo nucleosides 5-fluoro- and 5-azido-2,3-O-dibenzoyl-5-deoxy-1-O-methyl-1-(thymin-1-yl)-D-arabinitol (22). Compounds 20 and 22 were deprotected with methanolic ammonia to give the acyclic nucleosides 21 and 23, respectively. The new nucleosides were inactive against HSV-1 and HIV-1.

  三唑基13α-雌激素-核苷生物共轭物的合成及生物学评价。

  摘要：

  通过应用铜催化的炔-叠氮化物点击反应（CuAAC）合成了13α-雌酮的2'-脱氧核苷共轭物。为了引入叠氮基，选择了核苷的5'-位和13α-雌酮的3-羟基上的炔丙基醚官能团。当核苷的3'-羟基被乙酰基保护并且5'-羟基通过甲苯磺酰叠氮化物交换法进行修饰时，我们的手中获得了最佳收率。受保护的5'-叠氮核苷和甾类炔烃之间单击反应的常用条件通过使用1.5当量的Cu（I）催化剂进行了轻微修饰。所有制备的缀合物均通过MTT分析法在体外评估，其针对一组人类粘附细胞系（HeLa，通过体外放射性底物孵育研究了MCF-7和A2780）以及新缀合物对人17β-羟基类固醇脱氢酶1（17β-HSD1）的潜在抑制活性。一些受保护的缀合物对一组人类粘附癌细胞系表现出中等的抗增殖特性（受保护的胞苷缀合物被证明是最有效的，IC50值为9μM）。胸苷偶联物显示出相当大的17β-HSD1抑制活性（IC50 = 19μM）。一些

  This paper describes the synthesis of new click-generated nitrogen mustards and their biological evaluation. By using the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction, we managed to synthesize eight new nitrogen mustards. This strategy paves the way for the synthesis of a new family of nitrogen mustard, with an important structural variability. Furthermore, we studied the biological

  into 1,2,3-triazole linked sialyltransferase inhibitors, we present the design and synthesis of a new series of compounds that improve upon the drug-likeness of the parent scaffold. Additionally, we performed a preliminary SAR study with the STs hST3GAL1, hST6GAL1, and hST8SIA2. This work provides new insights into the design of selective ST inhibitors, particularly considering different nucleoside

• Development and characterization of lysine based tripeptide analogues as inhibitors of Sir2 activity

  Sirtuins are NAD(+) dependent deacetylases that modulate various essential cellular functions. Development of peptide based inhibitors of Sir2s would prove useful both as pharmaceutical agents and as effectors by which downstream cellular alterations can be monitored. Click chemistry that utilizes Huisgen's 1,3-dipolar cycloaddition permits attachment of novel modifications onto the side chain of lysine. Herein, we report the synthesis of peptide analogues prepared using click reactions on N epsilon-propargyloxycarbonyl protected lysine residues and their characterization as inhibitors of Plasmodium falciparum Sir2 activity. The peptide based inhibitors exhibited parabolic competitive inhibition with respect to acetylated-peptide substrate and parabolic non-competitive inhibition with NAD(+) supporting the formation of EI2 and E.NAD(+).I-2 complexes. Cross-competition inhibition analysis with the non-competitive inhibitor nicotinamide (NAM) ruled out the possibility of the NAM-binding site being the second inhibitor binding site, suggesting the presence of a unique alternate pocket accommodating the inhibitor. One of these compounds was also found to be a potent inhibitor of the intraerythrocytic growth of P. falciparum with 50% inhibitory concentration in the micromolar range. (C) 2009 Elsevier Ltd.
