Synthesis of benzotriazoles derivatives and their dual potential as alpha-amylase and alpha-glucosidase inhibitors in vitro: Structure-activity relationship, molecular docking, and kinetic studies

Benzotriazoles (4-6) were synthesized which were further reacted with different substituted benzoic acids and phenacyl bromides to synthesize benzotriazole derivatives (7-40). The synthetic compounds (7-40) were characterized via different spectroscopic techniques including EI-MS, HREI-MS, H-1-, and C-13 NMR. These molecules were examined for their anti-hyperglycemic potential hence were evaluated for alpha-glucosidase and alpha-amylase inhibitory activities. All benzotriazoles displayed moderate to good inhibitory activity in the range of IC50 values of 2.00-5.6 and 2.04-5.72 mu M against alpha-glucosidase and alpha-amylase enzymes, respectively. The synthetic compounds were divided into two categories A and B, in order to understand the structure-activity relationship. Compounds 25 (IC50 = 2.41 +/- 131 mu M), (IC50 = 2.5 +/- 1.21 mu M), 36 (IC50= 2.12 +/- 1.35 M), (IC50 = 2.21 +/- 1.08 mu M), and 37 (IC50 = 2.00 +/- 1.22 mu M), (IC50 = 2.04 +/- 1.4 mu M) with chloro substitution/s at aryl ring were found to be most active against alpha-glucosidase and alpha-amylase enzymes. Molecular docking studies on all compounds were performed which revealed that chloro substitutions are playing a pivotal role in the binding interactions. The enzyme inhibition mode was also studied and the kinetic studies revealed that the synthetic molecules have shown competitive mode of inhibition against alpha-amylase and non-competitive mode of inhibition against alpha-glucosidase enzyme.

Alloy CsCdxPb1-xBr3 Perovskite Nanocrystals: The Role of Surface Passivation in Preserving Composition and Blue Emission

Various strategies have been proposed to engineer the band gap of metal halide perovskite nanocrystals (NCs) while preserving their structure and composition and thus ensuring spectral stability of the emission color. An aspect that has only been marginally investigated is how the type of surface passivation influences the structural/color stability of AMX(3) perovskite NCs composed of two different M2+ cations. Here, we report the synthesis of blue-emitting Cs-oleate capped CsCdxPb1-xBr3 NCs, which exhibit a cubic perovskite phase containing Cd-rich domains of Ruddlesden-Popper phases (RP phases). The RP domains spontaneously transform into pure orthorhombic perovskite ones upon NC aging, and the emission color of the NCs shifts from blue to green over days. On the other hand, postsynthesis ligand exchange with various Cs-carboxylate or ammonium bromide salts, right after NC synthesis, provides monocrystalline NCs with cubic phase, highlighting the metastability of RP domains. When NCs are treated with Cs-carboxylates (including Cs-oleate), most of the Cd2+ ions are expelled from NCs upon aging, and the NCs phase evolves from cubic to orthorhombic and their emission color changes from blue to green. Instead, when NCs are coated with ammonium bromides, the loss of Cd2+ ions is suppressed and the NCs tend to retain their blue emission (both in colloidal dispersions and in electroluminescent devices), as well as their cubic phase, over time. The improved compositional and structural stability in the latter cases is ascribed to the saturation of surface vacancies, which may act as channels for the expulsion of Cd2+ ions from NCs.

Lasing from reduced dimensional perovskite microplatelets: Fabry-Perot or whispering-gallery-mode?

Cesium lead bromide (CsPbBr3) perovskite has attracted great attention recently for its potentials for next-generation green-color lasing devices owing to the relatively high structural stability and the high emission efficiency among the perovskite family. Herein, we explore the origins of cavity modes in CsPbBr3 microplatelets (MPs) lasers by using angle-resolved microphotoluminescence Fourier imaging technique, which is still controversial so far. In-plane Fabry-Perot (F-P) mode lasing transition to whispering-gallery-mode (WGM) lasing is verified at room temperature, which mostly occurs in large MPs with edge length (L) over 13 mu m. The F-P lasing is suppressed upon decreasing L or increasing excitation density, and the WGM lasing is predominant for all MPs at high excitation density. Furthermore, the parity and symmetry of in-plane F-P modes are classified. These results advance the fundamental understanding of lasing modes in planar microcavities as well as their applications in on-chip interconnection and quantum optics.

Investigation of poly(CTAB-MWCNTs) composite based electrochemical DNA biosensor and interaction study with anticancer drug Irinotecan

Development of sensitive, rapid and low-cost DNA detection tools and elucidation of the structural changes of DNA after interaction with chemotherapeutic drugs is of great significance. In this respect, the objective of this work was to construct a DNA biosensor based on electrodeposited cetyl trimethylammonium bromide-multiwalled carbon nanotubes (poly(CTAB-MWCNTs)) composite on single-use graphite electrodes (PGEs) for the direct detection of dsDNA and further implementation for the anticancer drug screening. The morphology and electrochemical characterization of the fabricated biosensor were utilized. The new surfactant-carbon nanotubes based electrode with porous composite structure led to significant improvement for the detection of dsDNA in the linear range of 4-150 mu g mL(-1) with detection limit of (LOD) 3.06 mu g mL(-1). Under the optimized conditions, the dsDNA modified poly(CTAB-MWCNTs)/PGEs were utilized to evaluate the binding interaction of an anticancer drug, irinotecan (CPT-11) with DNA by differential pulse voltammetry (DPV) and also by UV-vis spectroscopy. The guanine oxidation signal was linear in a CPT-11 concentration range of 2-500 mu g mL(-1) with LOD of 1.03 mu g mL(-1). Moreover, equilibrium constant (K) for the binding process was determined as 6.84 x 10(4 )M(-1). The applicability of the procedure was examined by quantitative measuring of CPT-11 in serum samples with high recoveries (106.0-98.2%). The proposed DNA biosensor hold considerable promise for different biointeraction applications.

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.

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.

Carbon Nanotubes Incorporated Z-Scheme Assembly of AgBr/TiO2 for Photocatalytic Hydrogen Production under Visible Light Irradiations

Photocatalytic H-2 production is a promising strategy toward green energy and alternative to carbon-based fuels which are the root cause of global warming and pollution. In this study, carbon nanotubes (CNTs) incorporated Z-scheme assembly of AgBr/TiO2 was developed for photocatalytic H-2 production under visible light irradiations. Synthesized photocatalysts were characterized through transmission electron microscope (TEM), X-ray photoelectron spectra (XPS), X-ray diffractometer (XRD), Fourier transform infrared (FTIR), photoluminescence spectra (PL), Brunauer Emmet-Teller(BET), and UV-vis spectroscopy analysis techniques. The composite photocatalysts exhibited a H-2 production of 477 ppm which was three-folds higher than that produced by TiO2. The good performance was attributed to the strong interaction of three components and the reduced charge recombination, which was 89 and 56.3 times lower than the TiO2 and AgBr/TiO2. Furthermore, the role of surface acidic and basic groups was assessed and the photocatalytic results demonstrated the importance of surface functional groups. In addition, the composites exhibited stability and reusability for five consecutive cycles of reaction. Thus, improved performance of the photocatalyst was credited to the CNTs as an electron mediator, surface functional groups, higher surface area, enhanced charge separation and extended visible light absorption edge. This work provides new development of Z-scheme photocatalysts for sustainable H-2 production.

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.

DNA and RNA binding studies on a novel bromo-bridged dimeric copper(II) complex stabilized from a Schiff base ligand

A novel red copper(II) compound, bis(mu-bromo)bis(2-(benzothiazol-2-yl-hydrazono)-1,2-diphenyl-ethanone)-dicopper(II) (1), has been fostered by equimolar reaction of a Schiff-base ligand, 2-(benzothiazol-2-yl-hydrazono)-1,2-diphenyl-ethanone (LH), with copper(II) bromide in satisfactory yield. 1 has thoroughly been characterized by C, H and N elemental analyses, FT-IR and UV-vis (both in solid state and in solution) spectroscopies, and room-temperature magnetic susceptibility and conductivity measurements. Dimeric 1 bears symmetric rare bromo-bridges in its crystal structure. 1 retains its solid-state identity even in a protic solvent like methanol. 1 in methanol displays two-step one-electron redox response. Theoretical calculations based on DFT were executed to probe the electronic structure of 1 and to augment its color. DNA- and RNA-binding aspects of both LH and 1 have been explored. Thermodynamic binding parameters have been determined. LH is a major-groove binder to DNA, while 1 manifests itself as a minor-groove binder. This binding has been corroborated through molecular docking. Nucleic acid binding aspect of such type of rare bromo-bridged red copper(II) dimer is unprecedented.

Ionic liquid functionalized beta-cyclodextrin and C18 mixed-mode stationary phase with achiral and chiral separation functions

A novel reversed-phase/hydrophilic interaction/ion-exchange (RPLC/HILIC/IEC) and chiral recognition mixed-mode stationary phase material was synthesized using 3-n-octadecyl-1-vinylimidazolium bromide and 6-(1-allylimidazolium)-cyclodextrin tosylate as functional monomers. After identifications of inter mediates and stationary phase materials using nuclear magnetic resonance analysis, Fourier transform infrared spectrometer, element analysis and thermogravimetric analysis, the synthesized Sil-VMBD material was packed into an empty column under high pressure. The mixed-mode retention performance was researched by hydrophobic, hydrophilic and ionic compounds. And the retention mechanism of the multi-mode stationary phase was studied via changing the mobile phase composition and pH value. Moreover, the enantiomers of 1-phenyl-1-propanol, warfarin and styrene oxide were separated rapidly under reverse-phase mode. Fast enantioseparation of ibuprofen and ketoprofen were obtained within 4 min under polar organic mode. The experimental results show that the as-prepared mixed-mode column possesses reversed-phase, hydrophilic and ion-exchange interactions with various analytes, and these interactions also enable the stationary phase with multi-mode and chiral separation abilities.
