α/β-肽是天然α-氨基酸残基与非天然β-残基的混合物。α/β-肽比α-肽更能抵抗蛋白酶的降解。α/β-肽模拟物已被报道具有多种生物活性的α-肽。生物靶点包括病毒-细胞融合、GPCR和血管生成。相对于α-肽,α/β-肽可以显示出强大的生物活性,在单链中组合天然α-氨基酸残基和非天然β-氨基酸残基导致称为α/β-肽的异质骨架寡聚体。尽管它们的骨架是非天然的,但α/β-肽可以表现出各种各样的折叠模式和生物学功能,让人联想到天然肽和蛋白质。此外,β-残基的掺入可以赋予寡聚体有用的性质,例如改善的对蛋白酶降解的稳定性。已经开发了α/β-肽,其参与不同的生物靶标,包括参与凋亡信号传导、HIV-细胞融合、激素信号传导和血管生成的蛋白质。对于某些系统,在体外获得的有希望的结果为证明体内活性铺平了道路,其中α/β-肽与α-肽对应物相比显示出相同的效力和改善的作用持续时间。
Highlightsα/β-Peptides blend natural α-amino acid residues with unnatural β-residues.α/β-Peptides are more resistant than α-peptides to degradation by protease enzymes.α/β-Peptide mimics have been reported for diverse bioactive α-peptides.Biological targets include viral-cell fusion, GPCRs, and angiogenesis.Relative to α-peptides, α/β-peptides can show potent, sustained activity in vivo.Combining natural α-amino acid residues and unnatural β-amino acid residues in a single chain leads to heterogeneous-backbone oligomers called α/β-peptides. Despite their unnatural backbones, α/β-peptides can manifest a variety of folding patterns and biological functions reminiscent of natural peptides and proteins. Moreover, incorporation of β-residues can impart useful properties to the oligomer such as improved stability to degradation by protease enzymes. α/β-Peptides have been developed that engage diverse biological targets, including proteins involved in apoptotic signalling, HIV-cell fusion, hormone signalling, and angiogenesis. For some systems, promising results obtained in vitro have paved the way for demonstrated activity in vivo, where α/β-peptides show equal potency and improved duration of effect compared to α-peptide counterparts.
