    缩氨基硫脲的功能化以实现共价结合
    摘要:
    缩氨基硫脲 (TSC) 具有模块化特征(缩氨基硫脲 + 羰基化合物),可在主 R1R2C=N(1)–NH–C(S)–N(4)R3R4 核心上实现最多四个取代基的广泛变化,因此是有趣的工具用于形成缀合物或纳米颗粒 (NP) 的功能化。在这项工作中,引入了二-2-吡啶基酮用于配位金属和 9-蒽醛作为 TSC 的 R1 和 R2 发光。 R3和R4取代基不同以形成缀合物。在 N4 位置引入氨基酸以产生 [R1R2TSC-间隔基-氨基酸]缀合物。此外,在 N4 位上引入膦酸 (R–P(O)(OH)2)、D-葡萄糖、邻氢醌、OH 和硫醇 (SH) 等功能,产生 [R1R2TSC–间隔基–锚定基团]用于直接 NP 锚定的缀合物。使用苯基、环己基、苄基、乙基和甲基作为间隔单元。两种苯基膦酸 TSC 衍生物均结合在 TiO2 纳米颗粒上,作为直接纳米颗粒锚定的第一个例子。 [R1R2TSC-间隔基-端基]

    氧化还原活性多巴胺对量子点光致发光的 pH 依赖淬灭
    摘要:
    我们研究了发光量子点 (QD) 和氧化还原活性多巴胺之间的电荷转移相互作用。为此,我们使用了 pH 不敏感的 ZnS 涂层 CdSe QD,使用聚(乙二醇)附加的二氢硫辛酸 (DHLA-PEG),其中一部分配体以胺为末端,以允许多巴胺的受控偶联-异硫氰酸盐到纳米晶体上。使用此样品配置,我们探讨了改变多巴胺密度和缓冲液 pH 值对这些偶联物荧光特性的影响。使用稳态和时间分辨荧光,我们测量了所有 QD-多巴胺组件的显着 pH 依赖性光致发光 (PL) 猝灭。有几个参数会影响 PL 损耗。首先,猝灭效率很大程度上取决于每个 QD 偶联物的多巴胺数量。第二,在碱性缓冲液中淬灭效率显着提高。第三,当使用缺氧缓冲液时,可以完全消除这种依赖于 pH 值的 PL 损失,这表明氧气在多巴胺的氧化还原活性中起着至关重要的作用。我们将这些发现归因于量子点与主要两种形式的多巴胺之间的电荷转移相互作用:还原的儿茶酚和氧化的醌。随着分散体的

  • METAL OXIDES NANOPARTICLES CONJUGATED WITH NAPHTHALENE DERIVATIVES AS CONTRAST AGENTS FOR THE DETECTION OF BETA AMYLOID PLAQUES BY MAGNETIC RESONANCE IMAGES

    This invention is related to Chemistry and Physics applied to the field of Medicine and refers to the use of compounds with magnetic properties, which belong to the category of metal oxide nanoparticles, coated and conveniently functionalized, which are conjugated with naphthalene compounds related to agglomerates and β-amyloid plaques present in neurodegenerative diseases. These new nanoparticles (NPs) are used for the non-invasive detection of agglomerates and amyloid plaques using the Magnetic Resonance Imaging (MRI) technique. The nanoparticles described here cross the blood-brain barrier (BBB), without the use of any membrane-disrupting agent. Likewise, they bind with high affinity and specificity to the agglomerates and β-amytoid plaques, and are used as contrast agents in MRI for the early detection of Alzheimer's disease (AD). The new nanoparticles, coated, functionalized and conjugated with the naphthalene derivatives, have general Formula I; wherein: R1: is an organic coating to the metal oxide core, of polymeric type, catechol derivatives and trialkoxyalkylaminosilane; R2: -NHCO-alkylenyl-C(O)NH-alkylenyl-R3; R3: -COO-, -CO-, -NH, -O-, -S-, -NH-alkylenyl-NH-, -NR4-CSS-; R4: -H, -CH3, -CH2-CH3, -CH2CH2CH3, and MxOy: iron oxide (Fe3O4/γFe2O3), gadolinium oxide(III), manganese oxide(II) and copper(II) oxide; wherein the conjugated, functionalized and coated magnetic nanoparticle is capable of, when it is administered to a mammal, crossing the blood-brain barrier and specifically binding to the agglomerates and amyloid plaques present in brain tissue; wherein with this nanoparticle bound to the agglomerates and β-amyloid plaques in the brain tissue, hypo- or hyper-intense signals are observed in the region of interest through MRI. The compounds of Formula I are capable of acting as positive (T1) and / or negative (T2) contrast agents for MRI for the early and non-invasive diagnosis of AD, through a hypo- or hyper-intense signal of the β-amytoid agglomerates or Aβ plaques. In the NPs of Formula I, the metallic oxide magnetic core is coated with a functionalized polymeric layer that allows conjugation to naphthalene compounds, the preparation of which has been previously described in CU 2010/0204, EP 2 436 666 A20, P58243ZA00, US 9,764,047, CA 2789869C, PI 2012003534. The covalent and stable bond between the two chemical units form, in the NPs, a carbon chain with a singular structure, which surprisingly facilitates the NPs passage through the BBB, without the use of a disrupting agent, what are not described in the current state-of-the-art. These NPs unexpectedly enhance the affinity and selectivity properties of the naphthalene derivatives towards the Aβ agglomerates and β-plaques, they are stable molecules and do not show toxicity. We are not aware that the compounds presented in this invention have been previously reported.

  • Multiple binding modes of isothiocyanates that inhibit macrophage migration inhibitory factor

    Macrophage migration inhibitory factor (MIF) is a pleiotropic cytokine that has roles in the innate immune response, and also contributes to inflammatory disease. While the biological properties of MIF are closely linked to protein protein interactions, MW also has tautomerase activity. Inhibition of this activity interferes with the interaction of MIF with protein partners e.g. the CD74 receptor, and tautomerase inhibitors show promise in disease models including multiple sclerosis and colitis. Isothiocyanates inhibit MIF tautomerase activity via covalent modification of the N-terminal proline. We systematically explored variants of benzyl and phenethyl isothiocyanates, to define determinants of inhibition. In particular, substitution with hydroxyl, chloro, fluoro and trifluoro moieties at the para and meta positions were evaluated. In assays on treated cells and recombinant protein, the IC50 varied from 250 nM to >100 mu M. X-ray crystal structures of selected complexes revealed that two binding modes are accessed by some compounds, perhaps owing to strain in short linkers between the isothiocyanate and aromatic ring. The variety of binding modes confirms the existence of two subsites for inhibitors and establishes a platform for the development of potent inhibitors of MIF that only need to target one of these subsites.
