transducer and activator of transcription 3 (STAT3) is a validated anticancer target due to the relationship between its constitutive activation and malignant tumors. Through a virtual screening approach on the STAT3-SH2 domain, 5,6-dimethyl-1H,3H-2,1,3-benzothiadiazole-2,2-dioxide (1) was identified as a potential STAT3 inhibitor. Some benzothiadiazole derivatives were synthesized by employing a versatile
由于其组成型激活与恶性肿瘤之间的关系,信号转导和转录激活因子 3 (STAT3) 是一种经过验证的抗癌靶标。通过对 STAT3-SH2 结构域的虚拟筛选方法,5,6-二甲基-1H,3H-2,1,3-苯并噻二唑-2,2-二氧化物 (1) 被鉴定为潜在的 STAT3 抑制剂。一些苯并噻二唑衍生物是通过采用通用方法合成的,并通过基于 AlphaScreen 的分析进行了测试。其中,苯磺酰胺 1 作为直接 STAT3 抑制剂显示出显着的活性,IC50 = 15.8 ± 0.6 µM。值得注意的是,我们发现化合物 1 也能够与位于 SH2 结构域周围的半胱氨酸残基相互作用。通过应用质谱、液相色谱、核磁共振和紫外光谱,进行了深入研究,
