kinetic stabilizer, using fibril inhibition potency and plasma TTR bindingselectivity data. Herein, we have successfully employed a substructure combination strategy to use these data to develop potent and selective TTR kinetic stabilizers that rescue cells from the cytotoxic effects of TTR amyloidogenesis. Of the 92 stilbene and dihydrostilbene analogues synthesized, nearly all potently inhibit TTR

4-(Nitrostyryl)phenols 2a–9a were synthesized, and by deprotonation in solution, the solvatochromic phenolates 2b–9b were formed. Their absorption bands in the vis region of the spectra are due to π–π* electronic transitions, of an intramolecularcharge-transfer nature, from the electron-donor phenolate toward the electron-acceptor nitroarene moiety. The frontier molecular orbitals and natural bond
