    • A solid-phase method for the synthesis of N-substituted oligomers, such as poly (N-substituted glycines) (referred to herein as poly NSGs) is used to obtain oligomers, such as poly NSGs of potential therapeutic interest which poly NSGs can have a wide variety of side-chain substituents. Each N-substituted glycine monomer is assembled from two "sub-monomers" directly on the solid support. Each cycle of monomer addition consists of two steps: (1) acylation of a secondary amine bound to the support with an acylating agent comprising a leaving group capable of nucleophilic is displacement by --NH.sub.2, such as a haloacetic acid, and (2) introduction of the side-chain by nucleophilic displacement of the leaving group, such as halogen (as a resin-bound .alpha.-haloacetamide) with a sufficient amount of a second sub-monomer comprising an --NH.sub.2 group, such as a primary amine, alkoxyamine, semicarbazide, acyl hydrazide, carbazate or the like. Repetition of the two step cycle of acylation and displacement gives the desired oligomers. The efficient synthesis of a wide variety of oligomeric NSGs using automated synthesis technology of the present method makes these oligomers attractive candidates for the generation and rapid screening of diverse peptidomimetic libraries. The oligomers of the invention, such as N-substituted glycines (i.e. poly NSGs) disclosed here provide a new class of peptide-like compounds not found in nature, but which are synthetically accessible and have been shown to possess significant biological activity and proteolytic stability.
    • 用于合成N-取代的低聚物(例如聚(N-取代的甘氨酸)(本文称为多聚NSG))的固相方法用于获得低聚物,例如聚NSG可具有的潜在治疗兴趣的聚NSG 各种各样的侧链取代基。 每个N-取代的甘氨酸单体直接在固体支持物上由两个“亚单体”组装。 单体添加的每个循环由两个步骤组成:(1)用包含能够亲核的离去基团的酰化剂与载体结合的仲胺的酰化被-NH 2取代,例如卤代乙酸,和(2)引入 的侧链通过亲核取代离去基团,例如卤素(作为树脂结合的α-卤代乙酰胺)与足够量的包含-NH 2基团的第二亚单体如伯胺,烷氧基胺, 氨基脲,酰肼,卡巴肼等。 重复酰化和置换的两个步骤循环,得到所需的低聚物。 使用本发明方法的自动化合成技术有效合成各种各样的低聚NSG使得这些寡聚物成为用于不同肽模拟文库的产生和快速筛选的有吸引力的候选者。 本文公开的本发明的低聚物,例如N-取代的甘氨酸(即多聚NSG)提供了一类新型的肽样化合物,它们在自然界中没有发现,但是它们是合成可及的,并且已被证明具有显着的生物活性和蛋白水解稳定性 。
