SELECTIVE DETECTION OF THIOLS
-
Page/Page column 32, (2013/09/12)
Probes for selectively detecting compounds comprising a thiol group and an amino group ("thiols") are disclosed. Exemplary thiols include cysteine, homocysteine, and glutathione. Embodiments of the disclosed probes produce a detectable change in absorbance spectrum and/or emission spectrum when reacted with one or more thiols in solution. Methods and kits for performing the detection also are disclosed. The probes have a general formula where each bond depicted as "ˉˉˉˉˉˉ " is a single or double bond; R1, R3-R6 and R8 independently are hydrogen, hydroxyl, thiol, lower alkyl, carboxyalkyl, amino, alkoxy, or halogen; R2 is an α,β-unsaturated aliphatic ester; R7 is oxygen, sulfur, hydrogen, hydroxyl, thiol, lower alkyl, carboxyalkyl, amino, alkoxy, or halogen, or R7 and R8 together form a cycloalkyl or aryl ring; X1 is CH2, S, NH, O, Se, Si(CH3)2, Ge(CH3)2, Sn(CH3)2, or C(CH3)2; and X2 is CH, CH2, N, NH, or CR9 where R9 is aryl.
