As an initial step, we have employed an improved solid-phase chemistry method to prepare a series of N6-substituted adenosine analogues and their 5′-phosphates as well as adenosine 5′-phosphate diesters bearing different Fe and S binding groups, such as thiols or carboxylic and hydroxamic acid moieties. Evaluation of the resulting compounds indicates a clearly defined spacing requirement between the
Helicobacter pylori are reported. Bloodgroup Antigen Binding Adhesin (BabA), a bacterial membrane-bound lectin, binds to human ABO and Lewis bbloodgroup structures displayed on the surface of host epithelial cells. Crystal structures of the carbohydrate-recognition domain revealed a conserved disulfide bonded loop that anchors a critical fucose residue in these bloodgroup structures. Disruption of this
报道了六种显示硫醇的单糖的合成,用于幽门螺杆菌的自杀抑制。血型抗原结合粘附素 (BabA) 是一种细菌膜结合凝集素,可与宿主上皮细胞表面显示的人 ABO 和 Lewis b 血型结构结合。碳水化合物识别域的晶体结构揭示了一个保守的二硫键环,该环将关键的岩藻糖残基锚定在这些血型结构中。N-乙酰半胱氨酸破坏该环会导致 BabA 介导的对人胃组织切片的粘附减少,并减弱表达 Lewis b 的转基因小鼠的毒力。为了创造凝集素的特异性抑制剂,我们设计并成功合成了六种具有硫醇基序的岩藻糖衍生化合物,与BabA的二硫键进行硫醇-二硫键交换,形成聚糖-凝集素二硫键。用 2-和 3-碳硫醇基序分支和延伸岩藻糖主链提供了一系列候选物,用于测试针对 BabA 的生物活性。

Attempts at synthesis of "chimeric" oligonucleotide constructs (PO/PS-Oligos) possessing phosphate and P-stereodefined phosphorothioate internucleotide linkages via combined phosphoramidite/oxathiaphospholane methods were unsuccessful. Therefore, novel monomers for oxathiaphospholane method, namely 5'-O-DMT-deoxyribonucleoside 3'-O-(2-oxo-spiro-4.4-pentamethylene-1.3.2-oxathiaphospholane)s, were prepared and used together with their diastereomerically pure 2-thio analogues for the stereocontrolled synthesis off "chimeric" oligonucleotide constructs (PO/PS-Oligos).
