It acts as a kinase inhibitor of a number of cell receptors, mainly the vascular endothelial growth factor receptor (VEGFR), the epidermal growth factor receptor (EGFR), and the RET-tyrosine kinase.in vitro: Vandetanib also inhibits VEGFR3 and EGFR with IC50 of 110 nM and 500 nM,respectively. Vandetanib is not sensitive to PDGFR β, Flt1, Tie-2 and FGFR1 with IC50 of 1.1-3.6 μM, while almost has no activity against MEK, CDK2, c-Kit, erbB2, FAK, PDK1, Akt and IGF-1R with IC50 above 10 μM. Vandetanib inhibits VEGF-, EGF- and bFGF-stimulated HUVEC proliferation with IC50 of 60 nM, 170 nM and 800 nM, with no effect on basal endothelial cell growth.

Poly(cytosine)-templated silver nanoclusters (C-Ag NCs) as a fluorescent probe, were used to present a fluorescence turn-off assay for biological substrates, which were more amenable to ultrasensitive assay of uric acid. Here, by a simple and nontoxic method, the water soluble C-Ag NCs were synthesized with an average size of 2.5nm and a stable emission at 565nm.The sensing mechanism was mainly based on the notion, that was, the oxidation of uric acid stimulated by uricase and coupled with the formation of H2O2, by which effective fluorescence quenching of C-Ag NCs. Under optimized conditions, detection of uric acid has a linear concentration range of 0.05 to 50μM with a detectable minimum concentration of 0.05μM. Therefore, C-Ag NCs as fluorescent probe can detect substrates based on H2O2–generating redox reaction and is further modified for analytical applications in vivo due to its superior optical properties and good biocompatibility. Keywords: C-Ag NCs; Fluorescence quenching; H2O2; Uric acid.
AR-A014418_DataSheet_MedChemExpress
Inhibitors, Agonists, Screening Libraries Data SheetBIOLOGICAL ACTIVITY:AR–A014418 is a selective and effective GSK3β inhibitor with an IC 50 value of 104 nM, and has no significant inhibition on 26 other kinases.IC50 & Target: IC50: 104 nM (GSK3β)In Vitro: AR–A014418 inhibits tau phosphorylation at a GSK3–specific site (Ser–396) in 3T3 fibroblasts expressing human four–repeat tau protein with IC 50 of 2.7 μM, and protects cultured N2A cells from death induced by blocking PI3K/PKB pathway. In hippocampal slices, AR–A014418 inhibits neurodegeneration mediated by beta–amyloid peptide [1]. While in NGP and SH–5Y–SY cells,AR–A014418 reduces neuroendocrine markers and suppresses neuroblastoma cell growth [2].In Vivo: In ALS mouse model with the G93A mutant human SOD1, AR–A014418 (0–4 mg/kg, i.p.) delays the onset of symptoms,improves motor activity, slows down disease progression, and postpons the endpoint of the disease [3]. In addition, AR–A014418produces inhibition effect on acetic acid– and formalin–induced nociception in mice by modulating NMDA and metabotropic receptor signaling as well as TNF–α and IL–1β transmission in the spinal cord [4].PROTOCOL (Extracted from published papers and Only for reference)Kinase Assay:[1]The competition experiments are carried out in duplicate with 10 concentrations of the inhibitor inclear–bottomed microtiter plates. The biotinylated peptide substrate, biotin–AAEELDSRAGS(PO3H2)PQL, is added at a final concentration of 2 μM in an assay buffer containing 6 milliunits of recombinant human GSK3 (equal mix of both α and β), 12mM MOPS, pH 7.0, 0.3 mM EDTA, 0.01% β–mercaptoethanol, 0.004% Brij 35, 0.5% glycerol, and 0.5 μg of bovine serumalbumin/25 μL and preincubated for 10–15 min. The reaction is initiated by the addition of 0.04 μCi of [γ–33P]ATP and unlabeled ATP in 50 mM Mg(Ac)2 to a final concentration of 1 μM ATP and assay volume of 25 μL. Blank controls without peptide substrate are used.After incubation for 20 min at room temperature, each reaction is terminated by the addition of 25 μL of stop solution containing 5mM EDTA, 50 μM ATP, 0.1% Triton X–100, and 0.25 mg of streptavidin–coated SPA beads corresponding to appr 35 pmol of binding capacity. After 6 h the radioactivity is determined in a liquid scintillation counter. Inhibition curves are analyzed by non–linear regression using GraphPad Prism.Cell Assay: AR–A014418 is dissolved in DMSO.[1]Cell viability is assessed by calcein/propidium iodide uptake. Calcein AM is taken up and cleaved by esterases present within living cells, yielding yellowish–green fluorescence, whereas PI is only taken up by dead cells,which become orange–red fluorescent. In brief, N2A cells are cultured for 2 days in vitro and then treated with 50 μM LY–294002 in the presence of AR–A014418 or vehicle (DMSO) for 24 h. Subsequently, N2A cells are incubated for 30 min with 2 μM PI and 1 μM calcein–AM. The cultures are then rinsed three times with Hanks' buffered saline solution containing 2 mM CaCl 2, and the cells are visualized by fluorescence microscopy using a Zeiss Axiovert 135 microscope. Three fields (selected at random) are analyzed per well (appr 300 cells/field) in at least three different experiments. Cell death is expressed as percentage of PI–positive cells from the total number of cells. In every experiment, specific cell death is obtained after subtracting the number of dead cells present inProduct Name:AR–A014418Cat. No.:HY-10512CAS No.:487021-52-3Molecular Formula:C 12H 12N 4O 4S Molecular Weight:308.31Target:GSK–3; GSK–3Pathway:Stem Cell/Wnt; PI3K/Akt/mTOR Solubility:10 mM in DMSOvehicle–treated cultures.Animal Administration: AR–A014418 is formulated in normal saline.[3]First, to examine the effects of GSK–3 inhibition on the clinical symptoms, life span, and motor behavior function of ALS, 56 Tg mice are divided into four groups. In each group, 0.5 mL of normal saline is mixed with either 0 μg (control group), 1 μg (group A), 2 μg (group B) or 4 μg (group C) of AR–A014418 per gram of mouse, and injected intraperitoneally into 14 animals per group 5 days a week beginning 60 days after birth. The mice are sacrificed at the endpoint described below.References:[1]. Bhat R, Xue Y, Berg S, Structural insights and biological effects of glycogen synthase kinase 3–specific inhibitor AR–A014418.

分子印迹复合膜对降糖药的拉曼光谱快速检测贾华;尹瑞林;钟旭;薛敏;赵瑜;孟子晖;汪群杰【期刊名称】《高等学校化学学报》【年(卷),期】2016(000)002【摘要】基于分子印迹技术的特异性识别特点,以假模板盐酸胍和4-(2-氨乙基)苯磺酰胺制备了2种分子印迹复合膜,用其对保健品中的二甲双胍、苯乙双胍和格列本脲进行吸附后,采用拉曼光谱法实现了保健品中降糖药的富集与快速检测。
考察了膜制备过程中纳米银的加入对拉曼光谱的增强作用,以及吸附样品浓度等的影响。
实验结果表明,盐酸胍分子印迹复合膜吸附5 mg/ mL 以上的二甲双胍或苯乙双胍后具有明显的拉曼响应,4-(2-氨乙基)苯磺酰胺印迹膜吸附10 mg/ mL 格列本脲后具有明显的拉曼响应。
所建立的分子印迹复合膜结合拉曼光谱检测方法可用于多种实际样品的检测。
%Some artificially synthesized anti-diabetic drugs are frequently found in health products to enhance their curative efficacy. Based on the specific recognition characteristics of molecularly imprinted technology, two kinds of molecularly imprinted composite membranes were prepared with dummy template of guanidine hydrochloride and 4-(2-aminoethyl)-benzene sulfonamide. The adsorption capacities of these two membranes to metformin hydrochloride, phenformin hydrochloride and glibenclamide were studied. Meanwhile, surface enhancement Raman spectrometry(SERS) to determine the target chemicals was established and employed in the membrane detection after infiltrated in the health products extract solution. The influence of nano-silver particles on themembrane to SERS was also studied. The detection limits of metformin hydrochloride, phen-formin hydrochloride and glibenclamide are 5, 5 and 10 mg / mL, respectively. This method was also proved by several pieces of real samples.【总页数】7页(P239-245)【作者】贾华;尹瑞林;钟旭;薛敏;赵瑜;孟子晖;汪群杰【作者单位】北京理工大学化工与环境学院，北京 100081;北京理工大学化工与环境学院，北京 100081;天津博纳艾杰尔科技有限公司，天津 300462;北京理工大学化工与环境学院，北京 100081;中国食品药品检定研究院，北京 100050;北京理工大学化工与环境学院，北京 100081;天津博纳艾杰尔科技有限公司，天津300462【正文语种】中文【中图分类】O657.37【相关文献】1.小牛胸腺DNA分子Langmuir-Blodgett复合膜的表面增强拉曼光谱研究 [J], 杨芳芳;方炎2.便携式拉曼光谱仪用于降糖药品快速检测的研究 [J], 罗娅;柳艳;胡茜茜;陆峰3.二苯并噻吩分子印迹复合膜的制备及脱硫性能的研究 [J], 黄振云; 陆向红; 计建炳4.氧化石墨烯杂化分子印迹复合膜制备及性能研究 [J], 毛东阳;杨丹;范杰平5.磁性氧化石墨烯基17β-雌二醇分子印迹复合膜的制备与性能 [J], 李颖;雷蕊;徐文凯;朱小雪;黄艳凤因版权原因，仅展示原文概要，查看原文内容请购买。
