Inhibition of KEAP1-NRF2 protein-protein interaction is considered a promising strategy to selectively and effectively activate NRF2, a transcription factor which is involved in several pathologies such as Huntington’s disease (HD). A library of linear peptides based on the NRF2-binding motifs was generated on the nonapeptide lead Ac-LDEETGEFL-NH2 spanning residues 76–84 of the Neh2 domain of NRF2
抑制KEAP1-NRF2蛋白质-蛋白质相互作用被认为是有选择地和有效地激活NRF2的一种有前途的策略,NRF2是一种转录因子,涉及多种病理学,例如亨廷顿舞蹈病(HD)。在非肽铅Ac-LDEETGEFL-NH 2上生成了基于NRF2结合基序的线性肽库跨越NRF2 Neh2域的76-84位残基,目的是用非酸性氨基酸取代E78,E79和E82。基于结构的设计还旨在更深入地了解T80副口袋的功能和可及性。研究了使用不同种类的环肽以及与细胞穿透肽结合的提高细胞通透性的方法。这一见识将指导大环化合物,肽模拟物以及最重要的是中性小脑穿透分子的未来设计,以评估NRF2激活剂是否可用于HD。
