In this study, the antibacterial, cytotoxic and antiproliferative activities of novel thiosemicarbazide derivatives were assessed. Our results demonstrated that some compounds possess good antibacterial properties against Staphylococcus epidermidis, Streptococcus mutans Streptococcussanguinis are only slightly cytotoxic; thus, they exhibit an excellent therapeutic index, which is higher than ethacridine lactate. Moreover, our data showed 2 4 have activity human breast adenocarcinoma...
The purpose of the research was to obtain new derivatives natural triterpene lupeol and evaluate their potential as active substances in treatment skin damage. Four esters (propionate, succinate, isonicotinate acetylsalicylate) acetate were obtained using an eco-friendly synthesis method. In esterification process, commonly used hazardous reagents this type replaced by safe ones. This unconventional, eco-friendly, method is particularly important because compounds are potentially care...
We report the synthesis, X-ray characterization and DFT study of five Hg(<sc>ii</sc>) complexes with Schiff bases containing a nicotinohydrazide core to explore formation chelate-ring π-stacking interactions.
We report the synthesis and X-ray characterization theoretical study of two Hg(<sc>ii</sc>) complexes with pincer-type isonicotinohydrazone Schiff base ligands to analyze chelate-ring π-stacked assemblies.
In recent years, the instability of hybrid organic‐inorganic halide perovskite solar cells (PSCs) has been an important challenge. The issue destruction as well a carrier density stability must be addressed to simultaneously achieve long lifetime PSCs and acceptable conversion efficiency. Present study aims address these issues by using all‐inorganic CsPbBr 3 light absorber material. Through simulation process, thickness was optimized yielding highest power efficiency (PCE) device reaching...
The regioselective
A new series of 1,2,4-triazine unsymmetrical disulfanes were prepared and evaluated as anticancer activity compounds against MCF-7 human breast cancer cells with some them acting low micromolar inhibitors. Evaluation the cytotoxicity using an MTT assay, inhibition [3H]-thymidine incorporation into DNA demonstrated that these products exhibit cytotoxic effects on in vitro. The most effective 59 60 µM compared to chlorambucil 47 bearing methyl methoxy substituent aromatic ring. Furthermore,...
In this study, the impact of calcination zeolites on ecotoxicity carbamazepine solutions in two matrices, water and synthetic sewage, was assessed. Two types were tested: natural zeolite, form a zeolite rock consisting mainly clinoptilolite, type 5 A. Additionally, calcined at temperature 200 °C. The kinetics adsorption aqueous sewage matrix determined. Higher capacity obtained for as well after process. Considering highest fastest uptake observed calcination. case ecotoxicity, before most...
Reactions between (E)-2-aryl-1-cyano-1-nitroethenes and diazafluorene lead to acyclic 2,3-diazabuta-1,3-diene derivatives, instead of the expected pyrazoline systems. DFT calculations suggest that this is a consequence formation zwitterionic structure in first stage reaction. It must be noted specific property group, contrast most other conjugated nitroalkenes.
A series of racemic, heteronuclear complexes [Zn2Nd(ac)2(HL)2]NO3·3H2O (1), [Zn2Sm(ac)2(HL)2]NO3·3CH3OH·0.3H2O (2), [Zn2Ln(ac)2(HL)2]NO3·5.33H2O (3–5) (where HL is the dideprotonated form N,N′-bis(5-bromo-3-methoxysalicylidene)-1,3-diamino-2-propanol, ac = acetate ion, and Ln Eu (3), Tb (4), Dy (5), respectively) with an achiral multisite coordination Schiff base ligand (H3L) were synthesized characterized. The X-ray crystallography revealed that chirality in centered at lanthanide(III) ions...
In the framework of this paper we describe a new, green procedure for synthesis series 1,2-oxazine N-oxide moieties via Hetero Diels-Alder (HDA) reaction with participation (2E)-3-aryl-2-nitroprop-2-enenitriles. For contrast most known HDA reactions, described process is realized without presence Lewis acid-type catalyst as well under mild conditions, full atomic economy and selectivity. Additionally, established, that can be characterized Molecular Electron Density Theory (MEDT).
5-(Nitromethyl)-3-phenyl-4,5-dihydroisoxazole was obtained as a product of high-yielding [3 + 2] cycloaddition reaction in situ-generated benzonitrile N-oxide and 3-nitroprop-1-ene. For the first time, regiochemistry this unambiguously proven by X-ray structural analysis. The quantum-chemical calculation performed at M06-2X/6-31G(d) (PCM) theoretical level affords basis for explaining course well nature transition states. Next, further DFT calculations together with spectral data shed light...
