体外研究 | Thioflavin T (ThT) is a benzothiazole dye that exhibits enhanced fluorescence upon binding to amyloid fibrils and is commonly used to diagnose amyloid fibrils, both ex vivo and in vitro. In aqueous solutions, Thioflavin T is found to exist as micelles at concentrations commonly used to monitor fibrils by fluorescence assay (~10-20 μM). Specific conductivity changes are measured at varying concentration of Thioflavin T and the critical micellar concentration is calculated to be 4.0±0.5 μM. Changes in the fluorescence excitation and emission of Thioflavin T are also dependent on the micelle formation. The Thioflavin T micelles of 3 nm diameter are directly visualized using atomic force microscopy, and bound Thioflavin T micelles are observed along the fibril length for representative fibrils. Increasing concentration of Thioflavin T above the critical micellar concentration shows increased numbers of micelles bound along the length of the amyloid fibrils. Thioflavin T micelles are disrupted at low pH as observed by atomic force microscopy and fluorescence enhancement upon binding of Thioflavin T to amyloid fibrils also reduced by several-fold upon decreasing the pH to below 3.The micelles of Thioflavin T bind amyloid fibrils leading to enhancement of fluorescence emission. |

硫黄素T,也被称为硫胺素T或维生素B1,是一种重要的维生素。
性质:
硫黄素T是一种水溶性白色结晶性粉末,具有微弱的味。它是稳定的,在光线、热和酸性条件下相对稳定。它在碱性环境下会迅速降解。
用途:
硫黄素T是一种必需的维生素,对维持人体正常的代谢功能至关重要。硫黄素T还被用于防治硫黄素T缺乏症,该病在饮食中缺乏硫胺素T时会引发。
制法:
硫黄素T可以通过化学合成的方法制备。最常用的方法是以1-甘醇-3-酮为起始原料,经过多步反应制得硫黄素T。硫黄素T也可以通过天然来源,如酵母和谷类中提取得到。
安全信息: 通常情况下,正常剂量的硫黄素T不会产生明显的副作用。过量摄入硫黄素T可能导致胃肠道不适或过敏反应。对于孕妇和有慢性疾病的人群,应在医师的指导下使用。
