The development of a fluorescent LCK inhibitor that exhibits favourable solvatochromic properties upon binding the kinase is described. Fluorescent properties were realised through the inclusion of a prodan‐derived fluorophore into the pharmacophore of an ATP‐competitive kinase inhibitor. Fluorescence titration experiments demonstrate the solvatochromic properties of the inhibitor, in which dramatic
描述了在结合激酶后显示出有利的溶剂变色性质的荧光LCK抑制剂的开发。荧光特性是通过在ATP竞争性激酶抑制剂的药效基团中包含前生荧光团来实现的。荧光滴定实验证明了该抑制剂的溶剂变色性质,其中在结合LCK时清楚地观察到发射强度的显着增加和发射最大值的变色移动。细胞环境中的显微镜实验以及流式细胞仪表明,抑制剂的荧光强度与LCK浓度相关。此外,
