Dipeptide analogs comprising a tryptophan (Trp) moiety coupled to a beta-sheet breaker moiety derived from alpha-aminoisobutyric acid (Aib) are disclosed. The dipeptide analogs exhibit an improved performance in inhibiting amyloid fibril formation, as compared to previously described dipeptides. Compositions containing the dipeptide analogs and uses thereof in treating amyloid-associated diseases and disorders are also disclosed.
