Synthesis of Enantiomerically Enriched Alkynylaryl-Substituted alpha-Amino Acids through Sonogashira Reactions

Various enantiomerically enriched non-proteinogenic (S)-alpha-amino acids were obtained in high chemical and optical yields through Sonogashira cross-coupling reactions and Glaser couplings. The Schiff base Ni(II)complexes of the chiral auxiliary (S)-BPB (BPB = N-benzyl proline benzophenone) and an amino acid containing an aryl bromide moiety in the alpha-position were synthesized and subsequently used in Sonogashira coupling reactions. The obtained Ni(II) complexes were hydrolyzed with aqueous HCl and novel amino acids, containing an alkynylaryl moiety, were isolated in good yields and with high enantiomeric excess (>99% ee). The chiral auxiliary (S)-BPB can be recycled and reused for the synthesis of the starting Ni(II) complex.

Fabrication of Cationic Surfactant (Conventional/Gemini) Functionalized Gr@ZrO2 Nanocomposite with Faster Adsorbability of an Anionic Azo Dye from Aqueous Solution

Graphene zirconium oxide nanocomposite (Gr@ZrO2-NC) has been functionalized with cetyltrimethylammonium bromide (CTAB or CT) or butanediyl-1,4, bis (N, N-hexadecyl ammonium) dibromide (cationic gemini surfactant (CGS)). Structural, morphological, optical and thermal properties of synthesized adsorbents (Gr@ZrO2-NC, CT-Gr@ZrO2-NC and CGS-Gr@ZrO2-NC) are investigated using XRD, FTIR, electron microscopy and TGA. CGS-Gr@ZrO2-NC showed faster removal efficacy (90 % within the first 25 min) for anionic azo dyes (methyl orange, MO and Congo red, CR) compared to other adsorbents. This effect may be due to the creation of stronger hydrophobic region at the surface of adsorbent with CGS. Effects of concentration, contact time and pH were also seen. The adsorption efficacy remained better even in the simultaneous presence of MO and CR. Adsorption data with time showed that the pseudo-second-order kinetic model has been obeyed. Adsorbents were regenerated successfully with ethylene glycol (similar to 83 %).

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 392-83-6 is helpful to your research. Safety of 2-Bromobenzotrifluoride.

Preparation and characterisation of magnetosomes based drug conjugates for cancer therapy

The authors report a novel, effective and enhanced method of conjugating anticancer drug, paclitaxel and gallic acid with magnetosomes. Here, anticancer drugs were functionalised with magnetosomes membrane by direct and indirect (via crosslinkers: glutaraldehyde and 3-aminopropyltriethoxysilane) adsorption methods. The prepared magnetosome-drug conjugates were characterised by Fourier transform infrared, zeta potential, field-emission scanning electron microscope and thermogravimetric analysis/differential scanning calorimetry. The drug-loading efficiency and capacity were found to be 87.874% for paclitaxel (MP) and 71.3% for gallic acid (MG), respectively as calculated by ultraviolet spectroscopy and high-performance liquid chromatography. The drug release demonstrated by the diffusion method in phosphate buffer (PBS), showing a prolonged drug release for MP and MG, respectively. The cytotoxicity effect of the MP and MG displayed cytotoxicity of 69.71%, 55.194% against HeLa and MCF-7 cell lines, respectively. The reactive oxygen species, acridine orange and ethidium bromide and 4, 6-diamidino-2-phenylindole staining of the drug conjugates revealed the apoptotic effect of MP and MG. Further, the regulation of tumour suppressor protein, p53 was determined by western blotting which showed an upregulation of p53. Comparatively, the magnetosome-drug conjugates prepared by direct adsorption achieved the best effects on the drug-loading efficiency and the increased percentage of cancer cell mortality and the upregulation of P53. The proposed research ascertains that magnetosomes could be used as effective nanocarriers in cancer therapy.

Tunable electrochemical synthesis of pyrrole-based adsorbents

Pyrrole-based adsorbents were developed electrochemically using systems: (i) pyrrole-potassium bromide, (ii) pyrrole-KBr-an anionic surfactant sodium dodecyl sulfate, and (iii) pyrrole-KBr-NaDS-Prussian blue. Growth kinetics and morphological studies were carried out at different experimental conditions. The study revealed the formation of nanosized particles, suitable for the removal of methylene blue as evident by high adsorption capacity = 447.7 mg g(-1). The effect of adsorption dosage, contact time, pH, and temperature on methylene blue removal has been studied. The data followed pseudo-second-order kinetic, Freundlich isotherm model and found to be endothermic and spontaneous in nature.

High-yield synthesis of gold bipyramids for in vivo CT imaging and photothermal cancer therapy with enhanced thermal stability

Monodisperse gold bipyramids (AuBPs) with controlled aspect ratio and tunable surface plasmon resonance (SPR) property have been synthesized using cetyltrimethylammonium bromide (CTAB) and sodium oleate (NaOL). The morphological yield of AuBPs is about 90% without any purification step. The presence of NaOL plays an important role in promoting the morphological yield of AuBPs by pre-reduce Au3+ to Au+. The obtained AuBPs exhibit strong absorbance in the near infrared region (NIR) that can be systematically tuned from 740 nm to 960 nm. After functionalized with polyethylene glycol (PEG), the as-prepared AuBPs have shown excellent photothermal stability and great biocompatibility, which could be used for high contrast computed tomography (CT) imaging and photothermal cancer therapy. This work provides not only a simple method for the synthesis of AuBPs with high morphological yield, but also a promising theranostic agent for cancer therapy.

Antiproliferative and proapoptotic activities of ferulic acid in breast and liver cancer cell lines

Purpose: To explore the potential anticancer activities of ferulic acid (4-hydroxy-3-methoxycinnamic acid, FA) on two different human cancers cell lines, viz, breast (MCF-7) and hepatocellular (HepG2). Methods: MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) cytotoxicity, Annexin V staining, enzyme-linked immunosorbent assay (ELISA), as well as caspase-8 and-9 activation assays were used to evaluate the proapoptotic and antiproliferative potentials of ferulic acid (FA) on MCF-7 and HepG2 cell lines. Results: Ferulic acid exerted cytotoxic effects on MCF-7 and HepG2 cell lines with half-maximal inhibitory concentration (IC50) of 75.4 and 81.38 mu g/mL, respectively, at 48 h. Annexin V staining revealed evidence of apoptosis. Caspase-8 and-9 levels were elevated in both cell lines after incubation with ferulic acid. Conclusion: The findings of this study suggest that ferulic acid has promising therapeutic potentials for the treatment of breast and liver cancers by inducing apoptosis via activation of caspase-8 and -9 pathways.

Aqueous solutions of hydroxyl-functionalized ionic liquids: Molecular dynamics studies

A series of aqueous solutions of 1-(n-hydroxyalkyl)-3-(n-hydroxyalkyl) imidazolium bromide ([HOC(n)C(m)OHIm][Br], with n and m = 2, 6,10 and 14) were studied by atomistic molecular dynamics simulations. Structural properties were characterized by the radial distribution functions between different pairs, angular distributions and aggregation numbers. Dynamics of the system has been investigated by computing the diffusion of the ions and molecules. Structures of the aggregates formed depend upon the length of the hydroxyalkyl chains. The long-distance spatial correlations observed in solutions with cations having long chain substituent are arising due to the formation of intercalated structures. A thin film like structure is formed in solutions having longer hydroxyalkyl chains, with the structure stabilized by the dispersion interactions between the interdigitated alkyl chains and the hydrogen bond formation between the hydroxyl group of a cation with head group of a different cation. Anions are dispersed near the surface of the film. (C) 2020 Elsevier Inc. All rights reserved.

Thin Film of Perovskite (Mixed-Cation of Lead Bromide FA(1-x)MA(x)PbBr) Obtained by One-Step Method

Perovskite materials for solar cell applications were prepared by a one-step method. In the following work, the spin coating technique was used for organic-inorganic hybrid perovskite formamidinium lead tribromide (FAPbBr(3)), methylammonium lead tribromide (MAPbBr(3)) and formamidinium methylammonium lead tribromide (FA(1-x)MA(x)PbBr(3)).Thin films of mixed FA(1-x)MA(x)PbBr(3) (x = 0-1) perovskites deposited on indium tin oxide glass substrates were obtained by mixing FAPbBr(3) and MAPbBr(3) in different proportions. Structural x-ray diffraction (XRD), morphological (Scanning Electron Microscopy (SEM) and energy dispersive x-ray spectroscopy (EDX) and optical (uv-visible spectroscopy (UV-Vis) proprieties were investigated for all synthesized perovskites as a function of the MA/FA ratio. The (XRD) analysis shows the formation of a cubic-phase perovskite with space group Pm-3 m in the composition range 0 <= x <= 1. High absorbance levels were obtained in the infrared region 500-900 nm for mixed perovskites FAMAPbBr(3). The estimated energy band-gap from the absorbance spectral measurements for FAMAPbBr(3) thin films was in the range of 2.2 eV for FAPbBr(3) and 2.3 eV for MAPbBr(3), respectively. The photoluminescence emission of mixed FA/MA perovskite thin films was located in intermediate values between 580 nm and 555 nm.

The theory of interceptor-protector action of DNA binding drugs

The review discusses the theory of interceptor-protector action (the IPA theory) as the new self-consistent biophysical theory establishing a quantitative interrelation between parameters measured in independent physico-chemical experiment and in vitro biological experiment for the class of DNA binding drugs. The elements of the theory provide complete algorithm of analysis, which may potentially be applied to any system of DNA targeting aromatic drugs. Such analytical schemes, apart from extension of current scientific knowledge, are important in the context of rational drug design for managing drug’s response by changing the physico-chemical parameters of molecular complexation.

Aqueous Two-Phase System Extraction of Polyketide-Based Fungal Pigments Using Ammonium- or Imidazolium-Based Ionic Liquids for Detection Purpose: A Case Study

Demand for microbial colorants is now becoming a competitive research topic for food, cosmetics and pharmaceutics industries. In most applications, the pigments of interest such as polyketide-based red pigments from fungal submerged cultures are extracted by conventional liquid-liquid extraction methods requiring large volumes of various organic solvents and time. To address this question from a different angle, we proposed, here, to investigate the use of three different aqueous two-phase extraction systems using either ammonium- or imidazolium-based ionic liquids. We applied these to four fermentation broths of Talaromyces albobiverticillius (deep red pigment producer), Emericella purpurea (red pigment producer), Paecilomyces marquandii (yellow pigment producer) and Trichoderma harzianum (yellow-brown pigment producer) to investigate their selective extraction abilities towards the detection of polyketide-based pigments. Our findings led us to conclude that (i) these alternative extraction systems using ionic liquids as greener extractant means worked well for this extraction of colored molecules from the fermentation broths of the filamentous fungi investigated here; (ii) tetrabutylammonium bromide, [N4444]Br-, showed the best pigment extraction ability, with a higher putative affinity for azaphilone red pigments; (iii) the back extraction and recovery of the fungal pigments from ionic liquid phases remained the limiting point of the method under our selected conditions for potential industrial applications. Nevertheless, these alternative extraction procedures appeared to be promising ways for the detection of polyketide-based colorants in the submerged cultures of filamentous fungi.
