QS activity in , an opportunistic human pathogen that causes disease in immunocompromised patients, with a set of probes containing a variety of functional groups, including photoreactive (diazirine) and affinity (alkyne) moieties, that were synthesized using a four-component Ugi reaction (Ugi-4CR).
群体感应(QS)是一种细胞密度依赖性信号通路,受
基因表达调节,用于种内和种间通讯。我们针对 QS 活性进行了靶向治疗,这是一种导致免疫功能低下患者患病的机会性人类病原体,我们使用了一组包含各种官能团的探针,其中包括光反应性(二嗪)和亲和性(炔)部分,这些探针是使用四组分合成的Ugi反应(Ugi-4CR)。
