Synthesis and evaluation of anthranilic acid-based transthyretin amyloid fibril inhibitors.
Eight small molecules were synthesized to evaluate the structure activity relationships (SAR) of N-substituted anthranilic acids. The molecules were synthesized by benzylation or arylation of methyl anthranilate. A light scattering-based amyloid fibril formation assay was used to evaluate potential inhibitors of transthyretin (TTR) amyloid fibril formation in vitro. The m-carboxyphenylated and o-trifluoromethylphenylated anthranilic acids are potent inhibitors that will be subjected to further SAR and structural analysis.
