A new family of peptide mimics termed ‘AApeptides’, which are oligomers of N-acylated-N-aminoethyl amino acids, was proposed. The design and efficient synthesis of AApeptides are described. As proof-of-the-concept, we show that AApeptides can inhibit p53/MDM2 protein–protein interaction with significant activity (IC50 = 38 μM) and specificity. Preliminary data also demonstrates that AApeptides are
提出了称为“ AApeptides”的肽模拟物的新家族,其是N-酰化的-N-氨乙基氨基酸的低聚物。描述了AA肽的设计和有效合成。作为概念验证,我们证明了Aa肽可以抑制p53 / MDM2蛋白之间的相互作用,并具有明显的活性(IC 50 = 38μM )和特异性。初步数据还表明,AA肽对酶促水解具有抗性。由于易于合成和多样化,强大的生物活性以及对蛋白水解的抵抗力,序列特异性AA肽的开发可能会扩大拟肽的潜在生物医学应用。
