二(乙酰氧基甲基酯)(6-羧基-2',7’-二氯二氢荧光素,二乙酸酯)

6-羧基-2',7'-二氯二氢荧光素二乙酸酯是一种化学还原型、乙酰化形式的荧光素,可用作细胞中活性氧 (ROS) 的指示剂。这种非荧光分子在细胞内容易被酯酶分解和 ROS 氧化,使乙酸酯基团脱去,转化为绿色荧光形式。我们提供了在生理 pH 值环境下带两个负电荷的羧基化了解更多信息

6-羧基-2',7'-二氯二氢荧光素二乙酸酯是一种化学还原型、乙酰化形式的荧光素,可用作细胞中活性氧 (ROS) 的指示剂。这种非荧光分子在细胞内容易被酯酶分解和 ROS 氧化,使乙酸酯基团脱去,转化为绿色荧光形式。我们提供了在生理 pH 值环境下带两个负电荷的羧基化 H2DCFDA 类似物(羧基-H2DCFDA,C400),以及其二(乙酰氧甲基酯) 形式 (C2938)。细胞内酯酶裂解乙酸酯和酯基团并氧化后,两种类似物均形成羧基二氯荧光素 (C368),并带有额外的负电荷,阻碍其渗出细胞。

Abstract
Differential efficacy of lipophilic and cytosolic antioxidants on generation of reactive oxygen species by amyloid-beta.
Authors:Dhitavat S, Rivera ER, Rogers E, Shea TB
Journal:J Alzheimers Dis
PubMed ID:12214018
'Exposure of neurons to amyloid-beta (Abeta) is accompanied by a cascade of oxidative damage that initiates with lipid peroxidation followed by subsequent generation of cytosolic free radicals and reactive oxygen species (ROS). The antioxidant vitamin E has been utilized to counteract Abeta-induced oxidative stress. We considered herein whether or not ... More
Mitochondrial localization of reactive oxygen species by dihydrofluorescein probes.
Authors:Diaz G, Liu S, Isola R, Diana A, Falchi AM
Journal:Histochem Cell Biol
PubMed ID:14574587
'Mitochondria are the main source of reactive oxygen species (ROS). The aim of this work was to verify the ROS generation in situ in HeLa cells exposed to prooxidants and antioxidants (menadione, tert-butyl hydroperoxide, antimycin A, vitamin E, N-acetyl-L-cysteine, and butylated hydroxytoluene) using the ROS-sensitive probes 6-carboxy-2'',7''-dichlorodihydrofluorescein diacetate di-acetomethyl ester ... More
NAD(P)H oxidase mediates the endothelial barrier dysfunction induced by TNF-alpha.
Authors:Gertzberg N, Neumann P, Rizzo V, Johnson A
Journal:Am J Physiol Lung Cell Mol Physiol
PubMed ID:12807699
'We tested the hypothesis that the NAD(P)H oxidase-dependent generation of superoxide anion (O2-*) mediates tumor necrosis factor-alpha (TNF)-induced alterations in the permeability of pulmonary microvessel endothelial monolayers (PMEM). The permeability of PMEM was assessed by the clearance rate of Evans blue-labeled albumin. The NAD(P)H oxidase subcomponents p47phox and p22phox were ... More
Prevention by anti-LFA-1 of acute myoblast death following transplantation.
Authors:Guérette B, Skuk D, Célestin F, Huard C, Tardif F, Asselin I, Roy B, Goulet M, Roy R, Entman M, Tremblay JP
Journal:J Immunol
PubMed ID:9278346
'Myoblast transplantation is a potential treatment for Duchenne muscular dystrophy. One of the problems possibly responsible for the limited success of clinical trials is the rapid death of the myoblasts after transplantation. To investigate this problem, myoblasts expressing beta-galactosidase were injected in the tibialis anterior muscles of mice. Beta-galactosidase activity ... More
Implication of mitochondrial hydrogen peroxide generation in ceramide-induced apoptosis.
Authors:Quillet-Mary A, Jaffrézou JP, Mansat V, Bordier C, Naval J, Laurent G
Journal:J Biol Chem
PubMed ID:9261153
'The key events implicated in ceramide-triggered apoptosis remain unknown. In this study we show that 25 microM C6-ceramide induced significant H2O2 production within 60 min, which increased up to 180 min in human myeloid leukemia U937 cells. Inactive analogue dihydro-C6-ceramide had no effect. Furthermore, no H2O2 production was observed in ... More
