标题:C3对称和不对称刚性分子形成的溶致性超分子螺旋柱状相
摘要:与具有柔性链的热致液晶c 3对称分子不同,本文设计的全刚性三臂分子(c 3对称和不对称)创建了一种花哨的结构,用于在水中形成溶致液晶.首先,通过刚性三臂分子的自组织自发构建具有三链螺旋的空心柱,类似于螺旋形的玫瑰花状碳纳米管.然后,螺旋纳米管排列成六角形液晶相,由于超分子手性对称性破坏,其表现出宏观手性.有趣的是,由完全刚性的分子构成的螺旋纳米管在水中的宽浓度范围内都具有坚固性和稳定性.它们几乎不受分子周边离子缺陷的影响,也就是说,推测可以在不改变螺旋构象的情况下进一步修饰分子臂上的官能团.此外,

摘要:The invention concerns a temperature-stable labelling reagent of formula (I), wherein: R<1> represents H or an alkyl, aryl or substituted aryl group; R<2> represents a detectable marker or at least two detectable markers linked together by at least a multimeric structure; L is a linking arm comprising a linear catemer concatenation of at least two covalent bonds; and n is an integer equal to 0 or 1; R<3> and R<4> represent, independently of each other: H, NO2, Cl, Br, F, I, R<2>-(L)n-Y-X-, OR, SR, NR2, R, NHCOR, CONHR, COOR with R = alkyl or aryl, A is a linking arm comprising at least a double bond enabling the conjugation of the diazo function with the aromatic cycle; and u is a whole number between 0 and 2, preferably between 0 and 1; and -Y-X- represents -CONH-, -NHCO-, -CH2O-, -CH2S-. The invention also concerns a method for the synthesis of said markers and uses for labelling biological molecules, in particular nucleic acids, with a labelling reagent bearing the diazomethyl function. The invention is particularly applicable in the field of diagnosis.

摘要:The present invention provides a new metal-free cyclotrimerization reaction of alkynes to produce a 1,3,5-triacylarylene or 1,3,5-triacylbenzene. This reaction is catalyzed by secondary amines, is strictly regioselective, highly functionality-tolerant, and the resulting product can be obtained in high yields. This reaction can be further applied for the preparation of novel branched (co)polymers bearing the triacylarylenes as structural units. The preparation of the (co)polymers is carried out as a one-pot single-step reaction procedure, giving branched oligomers and polymers in high yields up to 90%. The produced (co)polymers are also processible, easily film-forming, and thermally stable.

摘要:The present invention relates to a chemically modified mutant protein including a cysteine residue substituted for a residue other than cysteine n a precursor protein, the substituted cysteine residue being subsequently modified by reacting the cysteine residue with a glycosylated thiosulfonate. Also a method of producing the chemically modified mutant protein is provided. The present invention also relates to a glycosylated methanethiosulfonate. Another aspect of the present invention is a method of modifying the functional characteristics of a protein including providing a protein and reacting the protein with a glycosylated methanethiosulfonate reagent under conditions effective to produce a glycoprotein with altered functional characteristics as compared to the protein. In addition, the present invention relates to methods of determining the structure-function relationships of chemically modified mutant proteins. The present invention also relates to synthetic methods for producing thio-glycoses, the thio-glycoses so produced, and to methods for producing glycodendrimer reagents.

摘要:Multifunctional liquid phase carriers (LPCs) and methods of using LPCs for the preparation of biopolymers are provided. The LPCs are highly symmetrical compounds that possess more than two points of attachment for biopolymer synthesis. The LPCs have the formula Sp(X 1 ) n , where Sp is a highly symmetrical moiety such that all X 1 groups are equivalent. X 1 is a functional group that is suitable for biopolymer synthesis, including OH, SH, NH 2 , COOH and the like. Biopolymers that may be produced using the methods provided include oligonucleotides, peptides, protein nucleic acids (PNAs) and oligosaccharides. Analogs of the biopolymers may also be prepared using the methods.
