Complementary peptides are coded for by the nucleotide sequence (read 5'-->3') of the complementary strand of DNA. By reading the sequence of complementary DNA in the 3'-->5' direction, alternative complementary peptides may be derived. We describe the derivation, testing and analysis of six complementary peptides designed against beta-amyloid peptide 1-40 (Abeta, 40). Data is presented to show that one peptide, designated 3' -->5' betaCP1-15, binds specifically to Abeta 1-40, and inhibits both fibrilisation and neurotoxicity in vitro. This suggests that complementary peptides could be useful leads for drug discovery, especially where diseases of protein misfolding are concerned.
互补肽由DNA互补链的核苷酸序列(从5'→3'读取)编码。通过从3'→5'方向读取互补DNA序列,可以得到不同的互补肽。我们描述了针对β-淀粉样肽1-40(Aβ40)设计的六种互补肽的推导、测试和分析。数据表明,一种名为3'→5'βCP1-15的肽与Aβ1-40特异性结合,并在体外抑制纤维化和神经毒性。这表明互补肽可能是药物发现的有用线索,特别是在涉及蛋白质错误折叠疾病的情况下。
