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.

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.

A general asymmetric copper-catalysed Sonogashira C(sp(3))-C(sp) coupling

Continued development of the Sonogashira coupling has made it a well established and versatile reaction for the straightforward formation of C-C bonds, forging the carbon skeletons of broadly useful functionalized molecules. However, asymmetric Sonogashira coupling, particularly for C(sp(3))-C(sp) bond formation, has remained largely unexplored. Here we demonstrate a general stereoconvergent Sonogashira C(sp(3))-C(sp) cross-coupling of a broad range of terminal alkynes and racemic alkyl halides (>120 examples) that are enabled by copper-catalysed radical-involved alkynylation using a chiral cinchona alkaloid-based P,N-ligand. Industrially relevant acetylene and propyne are successfully incorporated, laying the foundation for scalable and economic synthetic applications. The potential utility of this method is demonstrated in the facile synthesis of stereoenriched bioactive or functional molecule derivatives, medicinal compounds and natural products that feature a range of chiral C(sp(3))-C(sp/sp(2)/sp(3)) bonds. This work emphasizes the importance of radical species for developing enantioconvergent transformations.

A rapid and simple method for the removal of dyes and organophosphorus pesticides from water and soil samples using deep eutectic solvent embedded sponge

A new treatment method using a deep eutectic solvent embedded melamine sponge (DES-MS) was studied for the removal of organic pollutants from water and soil samples. Five organophosphorus pesticides (OPPs) consisting of azinphos-methyl (AZP), parathion-methyl (PRT), fenitrothion (ENT), diazinon (DIZ) and chlorpyrifos (CPF), and two dyes including acid blue 29 (AB29) and malachite green (MG) were used as the model pollutants. DESs were easily prepared from tetrabutylammonium bromide (TBABr) and various fatty acids. The synthesised DESs were loaded into the sponge before being utilized for the removal of the studied pollutants. After the removal, the residual OPPs or dyes in the supernatant was quantified by high performance liquid chromatography or derivative spectrophotometry, respectively. The proposed method was simple, rapid, environmentally friendly and effective with the removal efficiency higher than 70% for various samples. Moreover, the removal of various dyes was successfully achieved with the efficiency greater than 65% under the optimum condition. (C) 2020 Elsevier Ltd. All rights reserved.

Surface-enhanced Raman scattering as a tool to study cationic surfactants exhibiting low critical micelle concentration

The collection of surface-enhanced Raman scattering (SERS) by silver nanocolloids was used to identify the critical micelle concentration (CMC) of three cationic surfactants in 0.5-M NaCl solutions: hexadecyltrimethylammonium bromide, dodecyltrimethylammonium bromide, and benzalkonium chloride. Despite structural similarity between the three test surfactans, differences of the shape and size of the respective micelles affected the corresponding SERS signals. The CMC values determined by this method agreed with the respective values measured by conventional methods, including fluorescence probing and electrical conductivity measurements. The potential for the application of SERS technique for low CMC determination without surface modification of silver nanoparticles by a Raman-active molecule was also demonstrated.

Dimension control of in situ fabricated CsPbClBr2 nanocrystal films toward efficient blue light-emitting diodes

In the field of perovskite light-emitting diodes (PeLEDs), the performance of blue emissive electroluminescence devices lags behind the other counterparts due to the lack of fabrication methodology. Herein, we demonstrate the in situ fabrication of CsPbClBr2 nanocrystal films by using mixed ligands of 2-phenylethanamine bromide (PEABr) and 3,3-diphenylpropylamine bromide (DPPABr). PEABr dominates the formation of quasi-two-dimensional perovskites with small-n domains, while DPPABr induces the formation of large-n domains. Strong blue emission at 470 nm with a photoluminescence quantum yield up to 60% was obtained by mixing the two ligands due to the formation of a narrower quantum-well width distribution. Based on such films, efficient blue PeLEDs with a maximum external quantum efficiency of 8.8% were achieved at 473 nm. Furthermore, we illustrate that the use of dual-ligand with respective tendency of forming small-n and large-n domains is a versatile strategy to achieve narrow quantum-well width distribution for photoluminescence enhancement. Designing efficient blue perovskite LEDs by using mixed halides perovskite is still a challenge, limited mainly by the phase segregation issue. Here, the authors demonstrate in situ fabrication of quasi-2D CsPbClBr2 nanocrystal films with mixed ligands to overcome the constraint.

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.

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.

The thermal/pH-sensitive drug delivery system encapsulated by PAA based on hollow hybrid nanospheres with two silicon source

The synthesis of drug delivery systems based on hollow mesoporous silica nanoparticles (MSNs) is still a major challenge. In this work, the hollow hybrid MSNs were successfully prepared by cetyltrimethylammonium bromide-directed sol-gel process and one-step hydrothermal treatment process. The hollow hybrid MSNs had hybrid ethane-bridged frameworks with the uniform particle size (250 nm) and mesoporous pore diameter (3.7 nm). The polyacrylic acid (PAA) encapsulated drug delivery system based on hollow hybrid MSNs was prepared by using silanization, surface modification, doxorubicin hydrochloride (DOX) loading, and PAA coating. Drug encapsulation and release behavior at different temperatures and pH were studied by using DOX as a model guest molecule. The results displayed that the modified hollow ethane-bridged MSNs possessed good biocompatibility and excellent thermal/pH-dual-sensitive drug release property. This novel thermal/pH-sensitive drug delivery system based on hollow ethane-bridged MSNs has the advantages of feasible synthesis, no cytotoxicity, and good drug loading capacity, which may have potential applications in the anticancer therapy.

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 %).
