development of a new “thiol conjugation assay” for identification of novel small molecules that bind to the TEAD central pocket. The assay monitors prevention of covalent binding of a fluorescence turn-on probe to a cysteine in the central pocket by small molecules. Screening of a collection of compounds revealed kojic acid analogues as TEAD inhibitors, which covalently target the cysteine in the central pocket
转录增强的缔合域(TEAD)转录因子与共激活因子和共加压因子一起调节调节基本过程(例如器官发生和细胞生长)的基因的表达,而升高的TEAD活性与肿瘤发生有关。因此,对TEAD的新型调节剂及其鉴定方法的需求很高。我们描述了一种新的“硫醇结合测定法”的发展,用于鉴定与TEAD中央囊袋结合的新型小分子。该测定监测小分子对荧光开启探针与中央口袋中半胱氨酸的共价结合的预防。筛选了一系列化合物后,发现曲酸类似物为TEAD抑制剂,可共价靶向中央口袋中的半胱氨酸,50个值,并减少TEAD靶基因的表达。这种方法有望实现旨在调节TEAD活性的新药物化学程序。
