permeability and offered proteolytic stability to the syntheticpeptides. Several peptides exhibited promising protection against Aβ aggregation-mediated-neurotoxicity in PC-12 cells at doses ranged between 10 μM and 0.1 μM, further confirmed by the thioflavin-T fluorescence assay. CD study illustrate that these peptides restrict the β-sheet formation, and the non-appearance of Aβ42 fibrillar structures in

l-allo-enduracididine (End) residue which is not readily accessible. In this report, we have used convergent Ser Ligation as the key step to prepare a series of teixobactin analogues with End being substituted with its non-isostere moieties. Among these analogues, compounds T16, T27 and T29 exhibited the best antimicrobial activities against different Gram-positive bacteria with MICs ranging from 0.25
