Photopharmacology develops bioactive compounds whose pharmacological potency can be regulated by light. The concept relies on the introduction of molecular photoswitches, such as azobenzenes, into the structure of bioactive compounds, such as known enzyme inhibitors. Until now, the development of photocontrolled protein kinase inhibitors proved to be challenging for photopharmacology. Here, we describe
光药理学开发了生物活性化合物,其药理作用可以通过光来调节。该概念依赖于将分子光开关例如偶氮苯引入生物活性化合物例如已知的酶抑制剂的结构中。迄今为止,光控蛋白激酶抑制剂的开发被证明对光药理学具有挑战性。在这里,我们描述了基于longdaysin支架的一类新的杂环偶氮苯,其旨在在昼夜节律的光调节范围内光调节酪蛋白激酶Iα(CKIα)的活性。评估一组可光转换的longdaysin衍生物可以更好地了解顺式取代基与热稳定性之间的关系-异构体。此外,我们对这类杂环偶氮苯中偶氮基化学稳定性的研究表明,在存在不同的还原剂的情况下,它们会快速还原为相应的肼。最后,我们尝试了对CKIα活性的光依赖性调节,以及伴随的直接参与CKIα的细胞昼夜节律的调节。详细的结构-活性关系(SAR)分析显示,新的强效偶氮嘌呤还原剂具有比其母体分子Longdaysin更显着的昼夜节律延长作用。共,
