标题:烷基β-D-硫代吡喃葡萄糖苷的合成及表面性质
摘要:烷基硫糖苷是一类非离子的基于糖的含硫表面活性剂和生物试剂.用helferich方法立体选择性地制备了具有不同烷基链长(n = 6-12)的表面活性剂1,2-反烷基β-D-硫代吡喃葡萄糖苷.主要研究了它们的性质,包括hlb值,Log P值,水溶性,泡沫性质,乳化性质,表面性质和热致液晶性质.结果表明,随着烷基链长的增加,Log B值增加,其hlb值和水溶性降低.烷基β-D-硫葡糖苷已经不溶于n>=10的水中.在临界胶束浓度(cmc)时,两种β-D-硫代吡喃葡萄糖苷(n = 8,9)都将相关水溶液的表面张力降低至近29 Mn.m-1.,它们还具有优异的起泡能力和泡沫稳定性.壬基β-D-硫代吡喃葡萄糖苷对正辛烷/水系统和甲苯/水系统均具有非常好的乳化性能.观测到烷基β-D-硫代吡喃葡萄糖苷(n = 6-12)具有热致液晶特性.

标 题 :Analogs of udp-murnac peptides, assays, kits and related methods of their use
发明人：AXELROD HELENA R; BRANSTROM ARTHUR A
摘要:General compositions and methods for detecting Lipid I, Lipid II and peptidoglycan synthesis is disclosed. A method of screening for potential antibacterial agents is provided which requires bacterial membrane preparations or enriched enzyme preparations including at least one bacterial enzyme involved in the synthesis of Lipid I from UDP-MurNAc pentapeptide and undecaprenyl phosphate, at least one bacterial enzyme involved in the synthesis of Lipid II from Lipid I and UDP-GlcNAc and one or more bacterial enzymes involved in the further processing of Lipid II toward the downstream synthesis of peptidoglycan. The methods disclosed herein further provides a labeled UDP-MurNAc-peptide capable of serving as a substrate for a bacterial enzyme involved in the synthesis of Lipid I and a labeled UDP-GlcNAc capable of serving as a substrate for a bacterial enzyme involved in the synthesis of Lipid II. Conditions for further processing of Lipid II toward the downstream synthesis of peptidoglycan are also discribed.

摘要:A method for producing a chondroitin sugar chain comprises reacting a glucuronic acid donor, an N-acetyl galactosamine donor, a sugar receptor and a bacterial cell enzyme which synthesizes chondroitin in the presence of a surfactant. The surfactant is selected from polyoxyethylene octadecyl amine, n-decanoyl-N-methylglucamide, sodium cholate, n-octyl-β-D-thioglucopyranoside, n-nonyl-β-D-thiomaltopyranoside, sucrose monocholate, sucrose monocaprate, and sucrose monolaurate. The chondroitin sugar chain has all the following properties: a weight average molecular weight: 50,000 or more when measured by gel filtration chromatography; it is completely degraded to disaccharides with chondroitinase ABC; and when the sugar chain is decomposed with chondroitinase ABC and the decomposed products are subjected to a disaccharide analysis, substantially all of them correspond to an unsaturated disaccharide unit of chondroitin.

摘要:According to the present invention, a composition possessing cell-free protein synthesis activity with reduced contaminating lipopolysaccharide, and a method for producing a protein using the same are provided. When ribosome display is performed using the composition and method for protein production of the present invention, the background that is caused by non-specific binding is reduced, so that a nucleic acid that encodes the desired polypeptide can be selected with high accuracy and high efficiency.
