Abstract
Ten oxazoles bearing a C(4) carboxyl group were synthesized and evaluated as transthyretin (TTR) amyloid fibril inhibitors. Substituting aryls at the C(2) position of the oxazole ring reveals that a 3,5-dichlorophenyl substituent significantly reduced amyloidogenesis. The efficacy of these inhibitors was enhanced further by installing an ethyl, a propyl, or a CF(3) group at the C(5) position. The CF(3) substitution at C(5) also improves the TTR binding selectivity over all the other proteins in human blood.
