This all-D peptide contains two retro-inverso peptide klvff motifs of KLVF corresponding to amino acids 16 to 20 of amyloid β-protein. The tandem dimer retro-inverso peptide showed about a 100-fold higher binding affinity (Kd = 1.3 · 10⁻² µM) for amyloid β-protein (1-40) fibrils than KLVFF (Kd = 1.1 ± 0.3 µM). It was also found to be more effective in preventing ordered fibril formation than the parent peptide KLVFF as judged by its increased ability to inhibit thioflavin T binding to β-sheet structures.
