标题:气体水合物的时间分辨原位中子衍射研究:结构 Ii (Sii) 到结构 I (Si) 的转化
摘要:我们报告了从具有结构 Ii (Sii) 晶格的气体水合物转化为具有结构 I (Si) 晶格的气体水合物的衍射数据的原位观察.最初,在 230 至 263 K 的温度和高达 5000 Psi (34.5 Mpa) 的压力下,通过飞行时间中子粉末衍射研究了氩气包合物水合物的原位形成,解离和反应性.这些样品由氘化冰晶制备,并通过用氩气对系统加压而转化为水合物.随着样品温度通过 D(2)O 冰熔点缓慢升高,观测到从 D(2)O 冰到 Sii Ar 水合物的完全转变.sii 氩水合物向 Si 水合物的转化是通过去除多余的 Ar 气体并通过用 Co(2) 对 Ar 水合物加压将水合物暴露于液态 Co(2) 来实现的.结果表明在氩 Sii 水合物中由 Co(2) 交换形成的 Si 水合物是混合的 Ar/co(2) 水合物.所提出的交换机制与笼形水合物是一种平衡系统一致,其中客体分子在固体水合物中的包封分

摘要:The subject invention provides methods for the chemical synthesis of racemic arsinothricin (D,L-AST), the novel organoarsenical antibiotic. One is by condensation of the 2-chloroethyl(methyl)arsinic acid with acetamidomalonate, and the second involves reduction of the N-acetyl-protected derivative of hydroxyarsinothricin (AST-OH) and subsequent methylation of the resulting sodium salt of trivalent arsenic intermediate with methyl iodide. The enzyme AST N-acetyltransferase (ArsN1) was utilized to purify L-AST from racemic AST. This expedient chemical synthesis of AST provides a source of this novel antibiotic for future drug development.

标 题 :Method for the synthesis of pyrrole and imidazole carboxamides on a solid support
发明人：DERVAN PETER B; BAIRD ELDON
权利人:CALIFORNIA INST OF TECHN
摘要:The present invention describes a novel method for the solid phase synthesis of polyamides containing imidazole and pyrrole carboxamides. The polyamides are prepared on a solid support from aromatic carboxylic acids and aromatic amines with high stepwise coupling yields (>99%), providing milligram quantities of highly pure polyamides. The present invention also describes the synthesis of analogs of the natural products Netropsin and Distamycin A, two antiviral antibiotics. The present invention also describes a novel method for the solid phase synthesis of imidazole and pyrrole carboxamide polyamide-oligonucleotide conjugates. This methodology will greatly increase both the complexity and quantity of minor-groove binding polyamides and minor-groove binding polyamide-oligonucleotide conjugates which can be synthesized and tested.

摘要:Disclosed is synthesis of an O-Antigen oligosaccharide compound of Helicobacter pylori serotype O2, belonging to the field of organic synthesis. The disclosure obtains O-antigen disaccharide to tetracosasaccharide of Helicobacter pylori serotype O 2 by chemical synthesis. A chemical synthesis method which is quite conducive to production of a glucose-α-lglucosidic bond is developed in the disclosure by a protectant strategy, temperature effect, solvent effect, and additive effect. The method is applied in synthesis of an O-antigen oligosaccharide compound of Helicobacter pylori serotype O2 assembled with an amino linking arm. A saccharide conjugate can be prepared from the synthesized O-antigen oligosaccharide compound of Helicobacter pylori serotype O2 assembled with an amino linking arm together with a carrier protein for immunology researches, playing an important role in preventing and treating Helicobacter pylori.
