synthesized five 2-phenyl-1,3,4-thiadiazole derivatives (PT2, PT5, PT8, PT9 and PT10) here based on the reported SHP1 inhibitors (PT1, PT3, PT4, PT6 and PT7). The photophysical properties and inhibitory activities of these 2-phenyl-1,3,4-thiadiazole derivatives (PT1–PT10) against SHP1 were thoroughly studied from the theoretical simulation and experimental application aspects. The representative compound
含有 Src 同源 2 结构域的蛋白酪氨酸磷酸酶 1 (SHP1) 主要限于造血细胞和上皮细胞,并被广泛接受为致癌细胞信号级联的会聚节点。开发有效的快速追踪和抑制复杂生物系统中SHP1活性的方法,对于推进相关疾病的诊治一体化具有重要意义。为此,我们在此基于已报道的 SHP1 抑制剂(PT1、PT3、PT4、PT6 和 PT7)设计并合成了五种 2-苯基-1,3,4-噻二唑衍生物(PT2、PT5、PT8、PT9 和 PT10)。 . 从理论模拟和实验应用两方面深入研究了这些2-苯基-1,3,4-噻二唑衍生物(PT1-PT10)对SHP1的光物理性质和抑制活性。由于激发态的几何弛豫和重组能较小,代表性化合物PT10比其他分子表现出更大的量子产率,这与有机溶剂中荧光实验的结果一致。此外,PT10 对 HeLa 细胞中的 SHP1 活性和低细胞毒性显示出选择性荧光反应。最后,根据计算出的优异的双光
