- Abstract
- Peptide derivatives 1e5, incorporating synthetic non-proteinogenic amino acids, related to the b-amyloid 17e21 fragment of the amyloidogenic
Ab1e40, and the N-protected decapeptide 6, corresponding to a dimeric sequence of the same fragment, have been synthesized. These
compounds were designed by using Soto's pentapeptide AceLPFFDeNH2 (iAb5p) as lead compound. Their activity as inhibitors of fibrillogenesis
and stability against enzymatic degradation have been determined. Compounds 1, 5 and 6 are potent inhibitors in comparison to the lead
compound. Exposure to chymotrypsin of peptide derivatives 1e5, all containing unnatural amino acids, shows increased stability as compared
with iAb5p and 6. Conformational properties of the new compounds have been determined by CD and FT-IR spectroscopies. (literal)
