A light scattering-based amyloidfibril formation assay was employed to evaluate potential inhibitors of transthyretin (TTR) amyloidfibril formation in vitro. Twenty nine aromatic small molecules, some with homology to flufenamic acid (a known non-steroidal anti-inflammatory drug) were tested to identify important structural features for inhibitor efficacy. The results of these experiments and earlier
properties of the compounds. 3‐3‐[4‐Chloro‐3‐(trifluoromethyl)phenyl]ureido}‐N‐[1‐(4‐methoxyphenyl)‐1H‐pyrazol‐4‐yl]benzamide was the most potent agent with IC50 values of 0.035±0.004 μm (B‐RafV600E kinase) and 0.39±0.04 μm (A375 cells). Furthermore, no obvious toxicity was observed. Collectively, the results favored justified the design rationale and hinted that this new chemotype might be worth studying
