  Potentiation of the tolerogenicity of benzylpenicilloylated eicosa-L-lysine by conjugation with 4-methoxybenzyl 3.beta.-cholestanyl succinate

  摘要：

  It was previously found that amino acid polymers such as oligolysines bearing haptenic groups in high densities efficiently suppress anti-hapten IgE antibody formation. Such conjugates are strong elicitors of anaphylaxis and therefore may not be used for desensitization of drug allergic patients. Here we report on the synthesis and immunological evaluation of benzylpenicilloylated (BPO) eicosa-L-lysines containing none, one, or two lipophilic p-(hydroxymethyl)benzyl cholestan-3 beta-yl succinate (OSuco) groups. The lipophilic derivatives suppress primary as well as ongoing anti-BPO IgE antibody formation in mice much more efficiently than their hydrophilic counterpart. The lipophilic but not the hydrophilic derivatives form stable micelles in water and suppress the antibody formation according to different cellular mechanisms. The relationship between structure, hydrophobicity, and mode of action is discussed.

  Calculating Canonical Distinguished Involutions in the Affine Weyl Groups

  摘要：

  Distinguished involutions in the affine Weyl groups, defined by G. Lusztig, play an essential role in the Kazhdan-Lusztig combinatorics of these groups. A distinguished involution is called canonical if it is the shortest element in its double coset with respect to the finite Weyl group. Each two-sided cell in the affine Weyl group contains precisely one canonical distinguished involution. We calculate the canonical distinguished involutions in the affine Weyl groups of rank less than or equal to 7. We also prove some partial results relating canonical distinguished involutions and Dynkin's diagrams of the nilpotent orbits in the Langlands dual group.

• Synthesis of Core-class 2<i>O</i>-Linked Glycopeptides: a Benzyl-protected Tetrasaccharyl Serine and its Derivative Carrying a Hydrophobic Cholestanyl Group

  A core-class 2 tetrasaccharide-linked serine was synthesized in a convergent manner. The coupling reaction of disaccharide glycosyl donor 3 and acceptor 4 stereoselectively afforded tetrasaccharide 15, which was converted to glycosyl fluoride 20. Glycosylation of Fmoc serine allyl ester 5 with 20 produced α- and β-glycosides in 40% and 33% yields, respectively. α-Isomer 21 was converted into 1, a useful building block for the solid-phase synthesis of glycopeptides. On the other hand, 21 was N-deprotected and condensed with hydrophobic cholestanol through a succinyl spacer. The same compound was alternatively synthesized by coupling 20 and 28. Functional group manipulation and hydrogenation afforded core 2 tetrasaccharide-cholestanol conjugate 2.

  一种核心类2的四糖链接丝氨酸以汇聚方式合成。双糖糖基给体3与受体4的偶联反应立体选择性地合成了四糖15，随后将其转化为糖基氟化物20。用20对Fmoc丝氨酸烯丙酯5进行糖基化反应分别以40%和33%的产率得到了α-和β-糖苷。α异构体21被转化为1，这是固相合成糖肽的有用构建模块。另一方面，21进行了N-脱保护，并通过琥珀酰间隔基与疏水的胆固醇醇缩合。同样，该化合物也可通过20与28的偶联反应来合成。功能基团的操控和氢化得到了核心2四糖-胆固醇醇结合物2。
