    生长抑素14(somatostatin)及其临床可用的类似物奥曲肽,兰瑞肽和伐普肽是生长激素,胰岛素和胰高血糖素释放的有效抑制剂。最近,描述了一种具有体内内分泌选择性的新型骨干环生长抑素类似物c(GABA-Phe-Trp-(D)Trp-Lys-Thr-Phe-GlyC3-NH(2))(类似物1,PTR 3173)。这种长效八肽对人重组生长抑素受体(hsst)hsst2,hsst4和hsst5具有高亲和力。其新颖的结合特性可有效抑制体内生长激素,但不能抑制胰岛素释放。我们报告了与1相关的化合物的合成,生物活性和构效关系研究。在这些类似物中,1的内酰胺桥被骨架二硫键取代。我们提出了一种新的方法,通过利用含硫的建筑单元对树脂骨架骨架化肽的构象约束。如在各种酶混合物中测试的,这些1的二硫键主链环状类似物显示出显着的代谢稳定性。受体结合测定揭示了与它们的原型相比,这些类似物的不同的受体选择性特征。发

    CD52 is a glycosylphosphatidylinositol (GPI)-anchored glycopeptide antigen found on sperm cells and human lymphocytes. Recent structural studies indicate that sperm-associated CD52 antigen carries both a complex type N-glycan and an O-glycan on the polypeptide backbone. To facilitate functional and immunological studies of distinct CD52 glycoforms, we report in this paper the first chemoenzymatic synthesis
    CD52 是一种糖基磷脂酰肌醇 (GPI) 锚定糖肽抗原,存在于精子细胞和人类淋巴细胞上。最近的结构研究表明,精子相关 CD52 抗原在多肽骨架上携带复合型 N-聚糖和 O-聚糖。为了促进不同 CD52 糖型的功能和免疫学研究,我们在本文中报告了第一次化学酶法合成均质 CD52 糖型N- 和 O-聚糖。合成策略包括两个关键步骤:单糖引物葡萄糖酸 和 加尔纳克 首先安装在预先确定的 N- 和 O-糖基化位点通过简单的固相肽合成,然后 N- 和 O-聚糖通过各自的酶促糖基化扩展。发现内切糖苷酶催化的转糖基化允许在 N-糖基化位点的一步中有效连接完整的 N-聚糖,而重组人 T-合酶可以独立地延长 O-连接的加尔纳克形成核心 1 O-聚糖。这种化学酶促方法具有高度收敛性,可以从常见的多肽前体轻松构建各种均质 CD52 糖型。此外,以受保护的形式引入潜在的硫醇基团半胱胺 在 CD52 糖型的 C 末

    Pancreatic cancer poorly responds to available drugs, and finding novel approaches to target this cancer type is of high significance. Here, based on a common property of pancreatic cancer cells to express somatostatin receptors (SSTR), we designed drug conjugates with novel somatostatin-derived cyclic peptides (SSTp) with broad selectivity towards SSTR types to facilitate drug targeting of the pancreatic cancer cells specifically. Uptake of our newly designed SSTps was facilitated by SSTRs expressed in the pancreatic cancers, including SSTR2, SSTR3, SSTR4 and SSTR5. Three major drugs were conjugated to our best SSTps that served as delivery vehicles, including Camptothecin (CPT), Combretastatin-4A (COMB) and Azatoxin (AZA). All designed drug conjugates demonstrated penetration to pancreatic cancer cell lines, and significant toxicity towards them. Furthermore, the drug conjugates specifically accumulated in tumors in the animal xenograft model, though some accumulation was also seen in kidney. Overall these findings lay the basis for development of novel drug series that could target the fatal pancreatic cancer.

In these analogues, the lactam bridge of 1 was replaced by a backbone disulfide bridge. We present a novel approach for conformational constraint of peptides by utilizing sulfur-containing building units for on-resin backbone cyclization. These disulfide backbone

    The present invention relates to a gp41 trivalent peptide mimetic having three gp41 N-peptides on a chemical scaffold which conformationally constrains the N-peptides into a trimeric coiled-coil to mimic gp41 presentation. The present invention also relates to N-peptides having the entire HIV gp41 NH2-terminal heptad repeat region and which are capable of forming gp41 peptide mimetics. Such peptide mimetics of HIV-1 gp41 pre-hairpin intermediates can be utilized in a vaccine for the treatment or prevention of HIV-1 infection through eliciting neutralizing antibodies.
