  Syntheses of α-d-galactosamine neoglycolipids

  摘要：

  Several N-acetyl-alpha-D-galactosamine neoglycolipids, as well as hydrophobized T and T-N antigen analogues, were prepared for embedment onto liposomes. Three different lipidic structures were used for the anchoring, that is cholesterol, 1,3-bis(undecyloxy)propan-2-ol and 1, 3-bis(3,7,11,15-tetramethyl hexadecyloxy) propan-2-ol. Oligoethyleneglycol spacers were used to link the carbohydrate and the hydrophobic moieties; their lengths were varied in order to obtain model compounds for the selective recognition by sialyl transferases involved in cancer processes. Glycosylation reactions were optimized to sluggish amphiphilic acceptor alcohols, in order to reach good 1,2-cis-stereoselectivities and acceptable yields. This aim was achieved by using 3,4,6-tri-O-acetyl-2-azido-2deoxy-D-galactopyranosyl trichloroacetimidate as the donor, trimethylsilyl trifluoromethanesulfonate as the promoter and diethyl ether or mixtures of diethyl ether and dichloromethane as solvents.

• ACID LABILE SURFACTANTS
  申请人：Waters Technologies Corporation

  公开号：US20190263774A1

  公开（公告）日：2019-08-29

  This invention relates to an acid labile surfactant. In particular, the surfactants of the present invention include a dioxolane or dioxane functional group which enables the surfactant to hydrolyze in an acidic environment. Surfactants of this type can be utilized to enhance protein solubilization/enzyme digestion. Following hydrolysis to destroy the surfactant (which may chromatographic issues), there are generally two components formed—a hydrophilic one, and a hydrophobic one. By altering the chemistry of the hydrolysable linker, the polarity of the hydrophobic residue can be altered, allowing it to be solubilized by significantly less organic solvent, and to minimize the potential loss of peptide material and to expand the chromatographic conditions that can be utilized.

  本发明涉及一种酸敏感表面活性剂。特别地，本发明的表面活性剂包括二氧兰或二氧杂环功能基团，使得表面活性剂能够在酸性环境下水解。这种类型的表面活性剂可用于增强蛋白质溶解/酶消化。在水解后破坏表面活性剂（可能会产生色谱问题）后，通常会形成两个组分 - 一个亲水性的组分和一个疏水性的组分。通过改变可水解连接剂的化学性质，可以改变疏水性残基的极性，使其能够被较少的有机溶剂溶解，并最小化肽材料的潜在损失，并扩展可利用的色谱条件。
