Dibenzofuran-4,6-Dicarboxylic Acid

Dibenzofuran-4,6-Dicarboxylic Acid is a small molecule identified as a potent and selective inhibitor of transthyretin (TTR) amyloidogenesis. It operates by kinetically stabilizing the native tetrameric structure of TTR, which is crucial for preventing the rate-limiting tetramer dissociation and subsequent monomer denaturation that leads to amyloid fibril formation. The drug binds to the outer portion of the thyroxine binding pockets of TTR, and structure-based design has been employed to enhance its potency and plasma TTR binding selectivity. This mechanism aims to create a barrier against amyloidogenesis under physiological conditions, offering a conservative strategy to intervene clinically in diseases associated with TTR misassembly.
