Facile, novel two-step syntheses of benzimidazoles, bis-benzimidazoles, and bis-benzimidazole-dihydroquinoxalines.

ABSTRACT: Three scaffolds of benzimidazoles, bis-benzimidazoles, and bis-benzimidazole-dihydroquinoxalines were synthesized via Ugi/de-protection/cyclization methodology. Benzimidazole forming ring closure was enabled under microwave irradiation in the presence of 10% TFA/DCE. The methodology demonstrates the utility of 2-(N-Boc-amino)-phenyl-isocyanide for the generation of new molecular diversity.

Facile syntheses of conjugated polymers for photothermal tumour therapy.

Project description:Development of photothermal materials which are able to harness sunlight and convert it to thermal energy seems attractive. Besides carbon-based nanomaterials, conjugated polymers are emerging promising photothermal materials but their facile syntheses remain challenging. In this work, by modification of a CBT-Cys click condensation reaction and rational design of the starting materials, we facilely synthesize conjugated polymers poly-2-phenyl-benzobisthiazole (PPBBT) and its dihexyl derivative with good photothermal properties. Under the irradiation of either sunlight-mimicking Xe light or near-infrared laser, we verify that PPBBT has comparable photothermal heating-up speed to that of star material single-wall carbon nanotube. Moreover, PPBBT is used to fabricate water-soluble NPPPBBT nanoparticles which maintain excellent photothermal properties in vitro and photothermal therapy effect on the tumours exposed to laser irradiation. We envision that our synthetic method provides a facile approach to fabricate conjugated polymers for more promising applications in biomedicine or photovoltaics in the near future.

Structural characterization of two solvates of a luminescent copper(II) bis-(pyridine)-substituted benzimidazole complex.

Project description:Copper(II) complexes of benzimidazole are known to exhibit biological activity that makes them of inter-est for chemotherapeutic and other pharmaceutical uses. The complex bis-(acetato-?O){5,6-dimethyl-2-(pyridin-2-yl)-1-[(pyridin-2-yl)meth-yl]-1H-benzimidazole-?2N2,N3}copper(II), has been prepared. The absorption spectrum has features attributed to intra-ligand and ligand-field transitions and the complex exhibits ligand-centered room-temperature luminescence in solution. The aceto-nitrile monosolvate, [Cu(C2H3O2)2(C20H18N4)]·C2H3N (1), and the ethanol hemisolvate, [Cu(C2H3O2)2(C20H18N4)]·0.5C2H6O (2), have been structurally characterized. Compound 2 has two copper(II) complexes in the asymmetric unit. In both 1 and 2, distorted square-planar N2O2 coordination geometries are observed and the Cu-N(Im) bond distance is slightly shorter than the Cu-N(py) bond distance. Inter-molecular ?-? inter-actions are found in 1 and 2. A weak C-H?? inter-action is observed in 1.

Bis-(benzimidazole-?N)bis(2-benzoyl-benzoato-?O)copper(II).

Project description:In the title centrosymmetric mononuclear copper(II) compound, [Cu(C(14)H(9)O(3))(2)(C(7)H(6)N(2))(2)], the central Cu(II) ion is coordinated by two N atoms from two symmetry-related benzimidazole (bim) ligands and two O atoms from two symmetry-related 2-benzoyl-benzoate (2-byba) ligands in a square-planar geometry. The mol-ecules are linked into chains running along the b axis by N-H?O hydrogen bonds and the chains are cross-linked by C-H?? inter-actions.

A Novel One-Step Fabricated, Droplet-Based Electrochemical Sensor for Facile Biochemical Assays.

Project description:A simple, novel concept for the one-step fabrication of a low-cost, easy-to-use droplet-based electrochemical (EC) sensor is described, in which the EC reagents are contained in a droplet and the droplet assay is operated on a simple planar surface instead of in a complicated closed channel/chamber. In combination with an elegant carbon electrode configuration, screen-printed on a widely available polyethylene terephthalate (PET) substrate, the developed sensor exhibits a stable solution-restriction capacity and acceptable EC response, and thus can be used directly for the detection of different analytes (including ascorbic acid (AA), copper ions (Cu(2+)), 2'-deoxyguanosine 5'-triphosphate (dGTP) and ferulic acid (FA)), without any pretreatment. The obtained, acceptable linear ranges/detection limits for AA, Cu(2+), dGTP and FA are 0.5-10/0.415 mM, (0.0157-0.1574 and 0.1574-1.5736)/0.011 mM, 0.01-0.1/0.008 mM and 0.0257-0.515/0.024 mM, respectively. Finally, the utility of the droplet-based EC sensor was demonstrated for the determination of AA in two commercial beverages, and of Cu(2+) in two water samples, with reliable recovery and good stability. The applicability of the droplet-based sensor demonstrates that the proposed EC strategy is potentially a cost-effective solution for a series of biochemical sensing applications in public health, environmental monitoring, and the developing world.

Differential gene expression after gamma radiation in bis-benzimidazole-treated human glioblastoma using microarray analysis

Project description:Radiation-induced DNA damage initiates a complex series of overlapping responses responsible for the maintenance of genome integrity. This study reports the expression analysis in response to DNA minor groove binding ligand (DMA-5-(4-methylpiperazin-1-yl)-2-[2’-(3,4-dimethoxyphenyl)-5`-benzimidazolyl] benzimidazole, an analogue of Hoechst 33342), with an emphasis on its ability to afford better protection in cells exposed to ionizing radiation. Four different types of samples were employed in the analysis: Control (untreated) cells, 50µM ligand-treated cells, 8.5Gy radiation-treated cells, and cells treated with 50µM ligand one hour prior to irradiation.

Facile Production of a Fenton-Like Photocatalyst by Two-Step Calcination with a Broad pH Adaptability.

Project description:A novel heterogeneous Fenton-like photocatalyst, Fe-doped graphitic carbon nitride (Fe-g-C3N4), was produced by facile two-step calcination method. This Fe-g-C3N4 catalyzed rhodamine B degradation in the presence of H2O2 accompanied with visible light irradiation. transmission electron microscopy(TEM), x-ray diffraction (XRD), FT-IR, x-ray photoelectron spectroscopy (XPS), and photoluminescence fluorescent spectrometer (PL) characterization analysis methods were adopted to evaluate the physicochemical property of samples. It can be observed that the Fe-g-C3N4 exhibited excellent photocatalytic Fenton-like activity at a wide pH range of 3-9, with rhodamine B(RhB) degradation efficiency up to 95.5% after irradiation for 45 min in the presence of 1.0 mM H2O2. Its high activity was ascribed to the formation of Fe-N ligands in the triazine rings that accelerated electron movement driving the Fe(III)/Fe(II) redox cycle, and inhibited photo-generated electron hole re-combinations for continuous generation of reactive oxygen species by reactions between Fe(II) and H2O2. The main active oxygen species were hydroxyl radicals, followed by superoxide radicals and hole electrons. This produced catalyst of Fe-g-C3N4 shows excellent reusability and stability, and can be a promising candidate for decontamination of wastewater.

A Facile Two-Step Enzymatic Approach for Conjugating Proteins to Polysaccharide Chitosan at an Electrode Interface.

Project description:Biological components are integrated with electronic devices to create microsystems with novel functions and chitosan, a naturally occurring biopolymer, can play a significant role as an interface material. Chitosan can be electrodeposited within confined geometries by cathodic charge and appropriate electrode design and proteins can be conjugated to chitosan. However, conjugation chemistries can be slow and chitosan, a polycationic polysaccharide, enables non-specific binding in biofabrication processes. There is a need to speed up the assembly process and reduce non-specific binding. Here, we have developed a two-step methodology that accelerates protein assembly, reduces background and increases specificity. We first "coated" the surface of chitosan with a Lys-Tyr-Lys (KYK) tripeptide in a slow step using tyrosinase-mediated conjugation chemistry and then conjugated proteins with C-terminal glutamine-tags to the saturating KYK tripeptide via transglutaminase. As a demonstration, we assembled a functioning two-enzyme bacterial metabolic pathway on an electrode chip. Results indicated a fivefold decrease in non-specific binding and an improvement in signal to noise ratio from 0.3 to 20. This transglutaminase-mediated approach is simple and quick, it requires no chemical reagents, no printing or stamping devices; it employs biological components and is biologically benign to the component parts-all characteristics of biofabricated devices.
