fluorimetric assay based on the hydrolysis of the artificial substrate Ala-Ala-Phe-amidomethylcoumarin. A series of di- and tripeptides having various alkyl or aryl side chains was studied to determine the accessible volume for binding and to probe the potential for hydrophobic interactions. From this initial study the tripeptides Ile-Pro-Ile-OH (K(i) = 1 microM) and Ala-Pro-Ala-OH (K(i) = 3 microM) and dipeptide

toxicity. Peptide 3 exhibited excellent cell viability of 94.3 % at 2 μM and of 100 % at 4 μM and 10 μM. CD study showed that peptide 3 restrict the conformation transition of Aβ1-42 peptide towards cross-β-sheet structure and electron microscopy validated the absence of Aβ aggregates as indicated by the altered morphology of Aβ1-42 in the presence of peptide 3. The HRMS-ESI, DLS and ANS studies were performed
