Page/Page column 0053; 0070-0072, (2020/06/09)
The invention relates to a triazole derivative as well as a preparation method and application thereof, which belong to the technical field of organic synthetic drugs. The structure of the triazole derivative is shown as a formula I. In the formula I, R1 and R2 are H, Cl, Br,-CF3,-CH(CH3)2 or -OCH3, and R1 and R2 are not H at the same time. R3 is -CH2 or -COCH2; X and Y are N or C, X and Y are not C at the same time, and X and Y are not N at the same time. The triazole derivative disclosed by the invention has a certain inhibition effect on germs of various crop diseases. Small toxic andside effects on plants are achieved. The preparation method of the triazole derivative is simple.

Transthyretin (TTR) is a homotetrameric protein. Its dissociation into monomers leads to the formation of fibrils that underlie human amyloidogenic diseases. The binding of small molecules to the thyroxin-binding sites in TTR stabilizes the homotetramer and attenuates TTR amyloidosis. Herein, we report on boronic acid-substituted stilbenes that limit TTR amyloidosis in vitro. Assays of affinity for TTR and inhibition of its tendency to form fibrils were coupled with X-ray crystallographic analysis of nine TTR·ligand complexes. The ensuing structure-function data led to a symmetrical diboronic acid that forms a boronic ester reversibly with serine 117. This diboronic acid inhibits fibril formation by both wild-type TTR and a common disease-related variant, V30M TTR, as effectively as does tafamidis, a small-molecule drug used to treat TTR-related amyloidosis in the clinic. These findings establish a new modality for covalent inhibition of fibril formation and illuminate a path for future optimization.
