Beta-Lactamase substrates and methods for using the substrates to detect beta-lactamase and to diagnose tuberculosis. In the method, a sample is contacted with a compound of the invention, and an optical signal generated from contacting the sample with the compound is measured. In another embodiment, the invention provides a method for diagnosing tuberculosis. In the method, a sample is contacted with a compound of the invention, and an optical signal generated from contacting the sample with the compound is measured. In the methods, the sample may be sputum, pleural fluid, spinal fluid, blood, urine, saliva, stool, tissue biopsies, tissue homogenates, directly in live animals or human patients, or a sample obtained by swabbing an area of interest on a subject.
Beta-Lactamase底物及其用于检测Beta-Lactamase和诊断结核病的方法。在该方法中,将样品与本发明的化合物接触,并测量与化合物接触后产生的光学信号。在另一种实施方式中,本发明提供了一种诊断结核病的方法。在该方法中,将样品与本发明的化合物接触,并测量与化合物接触后产生的光学信号。在这些方法中,样品可以是痰液、胸腔积液、脊髓液、血液、尿液、唾液、粪便、组织活检、组织匀浆、直接在活体动物或人类患者中,或通过在受试者感兴趣的区域刷取获得的样品。
