    用双砷探针探查靶蛋白对敏感蛋白酪氨酸磷酸酶的抑制作用†
    摘要:
    酶活性的选择性控制对于阐明特定蛋白在信号通路中的作用至关重要。开发真正的靶标特异性抑制剂的一种潜在手段包括使用蛋白质工程技术使靶标酶对不抑制同源野生型酶的小分子产生抑制作用。以前,已经显示蛋白质酪氨酸磷酸酶(PTP)可以被双砷探针FlAsH-EDT 2抑制。,通过与已引入催化重要区域的半胱氨酸残基特异性结合来抑制PTP活性。在本研究中,我们开发了一系列双砷探针,其中一些是新合成的,一些先前已报道过,以首次研究双砷抑制PTP的构效关系。我们的数据表明,在2'和7'位置含有取代的双砷探针在抑制致敏PTP方面比FlAsH-EDT 2更有效。当同时使用两种对位试剂测定PTP时,观察到2',7'-取代探针的效力增加-硝基苯基磷酸酯和磷酸肽PTP底物,并且处于多个探针浓度。数据进一步表明,增强的抑制特性是2',7'-取代的双砷探针与致敏PTP之间结合亲和力提高的结果。此外,我们为各种双砷探针提供了以前未知的理化和稳定性数据。

    A Design of Fluorescent Probes for Superoxide Based on a Nonredox Mechanism
    摘要:
    Fluorometric detection of O2-* is performed based on desulfonylation of 3 to the corresponding fluoresceins 4 through nucleophilic substitution, and this fluorescing process is quite specific toward O2-* over H2O2, t-BuOOH, NaOCl, 1O2, HO*, NO*, and ONOO-. Furthermore, effects of glutathione, cytochrome P450 reductase/NADPH, and diaphorase/NADH are relatively small on the fluorescing process of probe 3 with X = Y = F, which is useful to detect O2-* released from neutrophils stimulated by phorbol myristate acetate with satisfactory sensitivity.

  • Optically-Detectable Enzyme Substrates and Their Method of Use
    申请人:Life Technologies Corporation
    公开号:US20160139135A1
    公开(公告)日:2016-05-19
    The present invention relates to compounds that are substrates for an enzyme, and upon reaction with the enzyme provide a detectable response, such as an optically detectable response. In particular, the compounds have utility in detecting the presence of a β-lactamase in a sample. In addition to the compounds, methods are disclosed for analyzing a sample for the presence of a β-lactmase, for example, as an indicator of expression of a nucleic acid sequence including a sequence coding for a β-lactmase. Kits are disclosed that include the disclosed compounds and additional components, for example, cells, antibodies, a β-lactmase or instructions for using the components in an assay.

  • FLUORESCENT ISOTOPE TAGS AND THEIR METHOD OF USE
    申请人:Agnew Brian
    公开号:US20090017546A1
    公开(公告)日:2009-01-15
    The present invention provides novel reactive fluorescent compounds that incorporate stable isotopic (deuterium, 13-carbon, 15-nitrogen, 18-oxygen) substitutions. The invention includes the use of these compounds, in combination with non-isotopically substituted analogs, for the purification, identification and relative quantification of proteins, peptides, saccharides, metabolites, and other biologically important compounds by combining liquid chromatography (LC) and mass spectrometry (MS). Fluorescent labeling of target compounds in this manner provides orders-of-magnitude sensitivity enhancement over traditional stable isotope labels, and also affords the possibility of simultaneous multiplexed analysis due to the multiwavelength nature of different fluorophores.
    本发明提供了新型反应性荧光化合物,其中包含稳定同位素(氘,13-碳,15-氮,18-氧)取代。该发明包括使用这些化合物与非同位素取代的类似物结合,通过液相色谱(LC)和质谱(MS)相结合来纯化、鉴定和相对定量蛋白质、肽、糖、代谢物和其他生物重要化合物。以这种方式对目标化合物进行荧光标记提供了比传统的稳定同位素标记高几个数量级的灵敏度增强,并且由于不同荧光团的多波长性质,还提供了同时多重分析的可能性。
