  Ultra-trace determination of S-nitrosothiols in blood samples by spectrofluorimetry with 8-(3′,4′-diaminophenyl)-difluoroboradiaza-s-indacene

  摘要：

  increasing evidence suggests that S-nitrosothiols (RSNO) may represent naturally occurring nitric oxide (NO) surrogates and function as intermediates in NO metabolism. In this work, a simple, sensitive, and selective micromethod is developed and validated for quantification of RSNO. A fluorescent probe 8-(3',4'-diaminophenyl)-difluoroboradiaza-s-indacence (DABODIPY) is firstly used to label RSNO. The derivatization reaction is performed in aqueous medium at 30 degrees C for 15 min in the presence of 6 x 10(-5) mol L-1 Hg2+ and the derivative is detected by fluorescence at lambda(ex)/lambda(em) = 500/510 nm. A linear function of concentration in the range of (2.0-600.0) x 10(-8) mol L-1 is observed with a correlation coefficient of 0.9992 and detection limit of 1.2 x 10(-9) mol L-1 (S/N = 3). This technique has been successfully applied to quantify RSNO in some human blood samples including healthy persons and patients suffering from cardiovascular diseases. (C) 2007 Elsevier B.V.

  Development of a novel fluorescent probe for nitric oxide detection: 8-(3′,4′-diaminophenyl)-difluoroboradiaza-S-indacence

  摘要：

  A novel fluorescent probe, 8-(3',4'-diaminophenyl)-difluoroboradiaza-S-indacence (DABODIPY), was designed and synthesized for monitoring nitric oxide production, which features high photostability and no pH dependency over a wide pH range. The fluorescence of 8-(3',4'-diaminophenyl)-difluoroboradiaza-S-indacence is very low, however, when the probe traps nitric oxide (NO) in the presence of dioxygen, the strong fluorescent triazole form is obtained, which offers the advantages of specificity, and sensitivity for direct detection of NO. Calibration using various concentrations of NO showed the method has good linearity (0.08-4.00 mumol l(-1)) and its detection limit is 10 nmol l(-1) (s/n = 3). The proposed method has been used to monitor the release of NO from S-nitrosocysteine, a NO-releasing agent. (C) 2004 Published by Elsevier B.V.
