Combining X-ray data on thioflavin-T and theoretical calculations on its binding to a peptide model for Aβ1–42 fibrils gives evidence of main stabilizing interactions, which influence the dihedral angle between the two moieties of thioflavin-T and thereby its fluorescence properties; these results shed new light on possible strategies for the design of dyes to bind amyloid fibrils more specifically.
结合了硫黄素T的X射线数据以及其与Aβ1-42纤维肽模型结合的理论计算,证实了主要的稳定相互作用。这些相互作用影响硫黄素T两个部分之间的二面角,从而影响其荧光特性。这些研究结果为设计能更特异性结合淀粉样纤维的染料提供了新的思路。
