    • Embodiments of probes for selectively detecting compounds having a thiol group and an amino group, e.g., cysteine and/or homocysteine, are disclosed, along with methods and kits for detecting the compounds in neutral media with the probes. The probes have a structure according to the general formula where R1-R4 independently are hydrogen hydroxyl, halogen, thiol, thioether, lower aliphatic, or lower alkoxy, x is an integer from 0 to 4, and each R5 independently is halogen, hydroxyl, thiol, thioether, lower aliphatic, or lower alkoxy. Embodiments of the disclosed probes are capable of undergoing condensation/cyclization reactions with cysteine and/or homocysteine. Cysteine and/or homocysteine can be selectively detected and identified by determining fluorescence emission of the probes at characteristic wavelengths.
    • 公开了用于选择性检测具有硫醇基和氨基的化合物(例如半胱氨酸和/或同型半胱氨酸)的探针的实施方案,以及用于用探针检测中性培养基中的化合物的方法和试剂盒。 所述探针具有根据通式的结构,其中R 1 -R 4独立地是氢羟基,卤素,硫醇,硫醚,低级脂族或低级烷氧基,x是0-4的整数,每个R 5独立地是卤素,羟基, 硫醇,硫醚,低级脂族或低级烷氧基。 所公开的探针的实施方案能够与半胱氨酸和/或同型半胱氨酸进行缩合/环化反应。 半胱氨酸和/或同型半胱氨酸可以通过在特征波长处确定探针的荧光发射来选择性地检测和鉴定。
