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.

Chemoselective Union of Olefins, Organohalides, and Redox-Active Esters Enables Regioselective Alkene Dialkylation

Multicomponent catalytic processes that can generate multiple C(sp(3))-C(sp(3)) bonds in a single step under mild conditions, particularly those that employ inexpensive catalysts and substrates, are highly sought-after in chemistry research for complex molecule synthesis. Here, we disclose an efficient Ni-catalyzed reductive protocol that chemoselectively merges alkenyl amides with two different aliphatic electrophiles. Starting materials are readily accessible from stable and abundant feedstock, and products are furnished in up to >98:2 regioisomeric ratios. The present strategy eliminates the use of sensitive organometallic reagents, tolerates a wide array of complex functionalities, and enables regiodivergent addition of two primary alkyl groups bearing similar electronic and steric attributes across aliphatic C=C bonds with exquisite control of site selectivity. Utility is underscored by the concise synthesis of bioactive compounds and postreaction functionalizations leading to structurally diverse scaffolds. DFT studies revealed that the regiochemical outcome originates from the orthogonal reactivity and chemoselectivity profiles of in situ generated organonickel species.
