- Abstract
Transthyretin (TTR) is a homo-tetrameric protein characterized by four identical β-sheet rich monomers assembled together to form a tetramer that is crossed, along the 2-fold symmetry axis, by two similar binding pockets named thyroxin binding sites. Under unknown conditions, TTR can misfold and aggregate triggering the amyloidosis onset. One therapeutic approach consists to stabilize the tetramer with synthetic small molecules that bind TTR binding site hindering the first step of fibril formation. Here, we report the synthesis of new 2-((benzyloxy)imino)acetic, -propanoic and -butanoic acid derivatives, results of their turbidimetric UV assay and the docking study of new monoaryl compounds. The obtained results suggest that, for this class of compounds, (i) the chlorine atom in ortho position on the aromatic ring is the best substituent; (ii) the linker inversion still allows the interaction with thyroxine binding sites; and (iii) the steric hindrance in R1 position is detrimental for the activity.
