  具有TN和T抗原结构的糖肽的合成及其与牛血清白蛋白的偶联。

  摘要：

  合成了具有TN和T抗原结构的糖肽，这些肽代表具有血型M特异性的去唾液酸糖蛋白的N端三肽，已使用芴基甲氧基羰基（Fmoc）和2-吡啶基乙氧基羰基（Pyoc）基团进行氨基保护，并使用苄基酯作为羧基封闭基团来合成糖肽功能。Fmoc和Pyoc基团可以通过在碱敏感的O-糖基丝氨酸和-苏氨酸键稳定的条件下用弱碱吗啉处理而除去。用甲醇肼从碳水化合物部分除去酯基，得到TN和T抗原糖肽，其通过碳二亚胺方法与牛血清白蛋白（BSA）偶联，并且没有任何间隔基。所得的缀合物每个蛋白质分子平均包含大于20个糖肽。

• Synthetic and Immunological Studies on Clustered Modes of Mucin-Related Tn and TF O-Linked Antigens:  The Preparation of a Glycopeptide-Based Vaccine for Clinical Trials against Prostate Cancer

  The syntheses of two tumor-associated carbohydrate antigens, Tn and TF, have been achieved using glycal assembly and cassette methodologies. These synthetic antigens were subsequently clustered (c) and immunoconjugated to a carrier protein (KLH or BSA) or a synthetic lipopeptide (pam) for immunological study. Three Tn conjugates were used to vaccinate groups of mice, and all preparations proved to be immunogenic. The Tn(c) covalently linked to KLH (27-KLH) plus the adjuvant QS-21 was the optimal vaccine, inducing high median IgM and IgG titers against Tn(c) by ELISA. These antibodies were strongly reactive with the Tn(c) positive human colon cancer cell line LS-C but not the Tn(c) negative colon cancer cell Line LS-B by FAGS. The antibodies' reactivities with natural antigens were inhibited with synthetic Tn(c) but not with structurally unrelated compounds. On the basis of these results, vaccines containing 27-KLH and 30-pam plus QS-21 are being tested in patients with prostate cancer.
• α-Selective glycosylation affords mucin-related GalNAc amino acids and diketopiperazines active on Trypanosoma cruzi

  This work addresses the synthesis and biological evaluation of glycosyl diketopiperazines (DKPs) cyclo[Asp-(alpha GalNAc)Ser] 3 and cyclo[Asp-(alpha GalNAc)Thr] 4 for the development of novel anti-trypanosomal agents and Trypanosoma cruzi trans-sialidase (TcTS) inhibitors. The target compounds were synthetized by coupling reactions between glycosyl amino acids alpha GalNAc-Ser 7 or alpha GalNAc-Thr 8 and the amino acid (O-tBu)-Asp 17, followed by one-pot deprotection-cyclisation reaction in the presence of 20% piperidine in DMF. The protected glycosyl amino acid intermediates 7 and 8 were, in turn, obtained by a-selective, HgBr2-catalysed glycosylation reactions of Fmoc-Ser/Thr benzyl esters 12/14 with alpha GalN(3)Cl 11, being, subsequently, fully deprotected for comparative biological assays. The DKPs 3 and 4 showed relevant anti-trypanosomal effects (IC50 282-124 mu M), whereas glycosyl amino acids 1 and 2 showed better TcTS inhibition (57-79%) than the corresponding DKPs (13-25%).
