Application of capillary electrophoresis technique for the enantioseparation of bioactive ferrocene-based compounds versus DFT calculated data

Herein, a series of bioactive ferrocene-modified N-heterocycles with alkyl linkers was prepared in good to quantitative yields starting from easy accessible ferrocene alcohols and heterocycles under acidic or neutral (for imidazole) conditions in racemic forms. The analytical resolution of a number of bioactive racemic ferrocene azoles 1-6 (where azole = imidazole, pyrazole, and benzotriazole derivatives) into enantiomers was first carried out by CE using sulfobuthylether-beta-CD (captisol) as a chiral selector. The analytical approaches to highly enantiomeric-enriched ferrocene derivatives are based on the formation of their inclusion complexes. The best chiral separation was achieved using zone CE in a quartz capillary. The ACE was used to evaluate the stability constants of captisol complexes with enantiomeric forms of two ferrocene derivatives 1, FcCHMe-imidazole, and 6, FcCHMe-benzotriazole. The optimal conditions for the resolution of the studied (R, S)-ferrocene compounds 1, 2, and 6 were predicted on the basis of the performed quantum chemical calculations and then implemented by the electrophoretic method. A high correlation between density functional theory calculation results and experimental electrophoresis data were obtained. Successful enantioseparation of racemic mixtures is of great importance for the characterization and further applications of drug candidates in enantiopure forms and in the development of clinical treatment. The advantages of the CE procedure make it possible to have important practical value and significance for determining the purity and enantiomeric excess of other ferrocene-containing compounds.

Transition-Metal-Free C-S Bond Forming Strategy towards Synthesis of Highly Diverse Pyrazole Tethered Benzothiazoles: Investigation of their Photophysical Properties

A metal-free domino approach has been devised towards construction of two C-S bonds for the synthesis of bioactive N, S-heterocycles. The developed method was extended for the preparation of structurally diverse pyrazole tethered benzothiazole frameworks by using one-pot operation of pyrazole C-3/4/5 carbaldehydes, electron rich aromatic amines and elemental sulfur. This protocol provides excellent fluorophores with several additional advantages such as transition metal-free approach, inexpensive and odorless sulfur source, superior atom economy, and broad substrate scope including gram scale synthesis. The synthesized pyrazole tethered benzothiazole fluorophores were evaluated for their luminescent properties including absorbance, excitation, emission, molar extinction coefficient, brightness, and Stokes shift. The photophysical studies revealed that these pyrazole and benzothiazole hybrids emerged as excellent fluorophores and could exhibit fluorescence quantum yield up to 66%.

New 1,2,3-Triazole-Containing Hybrids as Antitumor Candidates: Design, Click Reaction Synthesis, DFT Calculations, and Molecular Docking Study

In an effort to improve and achieve biologically active anticancer agents, a novel series of 1,2,3-triazole-containing hybrids were designed and efficiently synthesized via the Cu-catalyzed azide-alkyne cycloaddition (CuAAC) reaction of substituted-arylazides with alkyne-functionalized pyrazole-[1,2,4]-triazole hybrids. The structure geometry of these new clicked 1,2,3-triazoles was explored by density functional theory (DFT) using the B3LYP/6-311++G(d,p) level; also, the potential activity of the compounds for light absorption was simulated by time-dependent DFT calculations (TD-DFT). The antitumor impacts of the newly synthesized compounds were in vitro estimated to be towards the human liver cancer cell line (HepG-2), the human colon cancer cell line (HCT-116), and human breast adenocarcinoma (MCF-7). Among the tested compounds, conjugate 7 was the most potent cytotoxic candidate towards HepG-2, HCT-116, and MCF-7, with IC50 = 12.22, 14.16, and 14.64 mu M, respectively, in comparison to that exhibited by the standard drug doxorubicin (IC50 = 11.21, 12.46, and 13.45 mu M). Finally, a molecular docking study was conducted within the epidermal growth factor receptor (EGFR) active site to suggest possible binding modes. Hence, it could conceivably be hypothesized that analogies 7, 6, and 5 could be considered as decent lead candidate compounds for anticancer agents.

Functionalisation of Fe(3)O(4)nanoparticles by 2-((pyrazol-4-yl) methylene) hydrazinecarbothioamide enhances the apoptosis of human breast cancer MCF-7 cells

Cancer is a major cause of death. Thus, the incidence and mortality rate of cancer is globally important. Regarding vast problems caused by chemotherapy drugs, efforts have progressed to find new anti-cancer drugs. Pyrazole derivatives are known as components with anti-cancer properties. In here, Fe(3)O(4)nanoparticles were first functionalized with (3-chloropropyl) trimethoxysilane, then 2-((pyrazol-4-yl) methylene) hydrazinecarbothioamide (P) was anchored on the surface of magnetic nanoparticles (PL). The synthesized nano-compounds were characterized using Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, Zeta potential, dynamic light scattering, and energy-dispersive x-ray spectrometry analyses. The cytotoxicity effect was evaluated using MTT assay, apoptosis test by Flow cytometry, cell cycle analysis, Caspase-3 activity assay and Hoechst staining on MCF-7 cell line. The high toxicity for tumor cells and low toxicity on normal cells (MCF10A) was considered as an important feature (selectivity index, 10.9). Based on results, the IC50 for P and PL compounds were 157.80 and 131.84 mu M/ml respectively. Moreover, apoptosis inducing, nuclear fragmentation, Caspase 3 activity and induction of cell rest in sub-G1 and S phases, were also observed. The inhibitory effect of PL was significantly higher than P, which could be due to the high penetrability of Fe(3)O(4)nanoparticles.

Tungstic acid (H4WO5) immobilized on magnetic-based zirconium amino acid metal-organic framework: An efficient heterogeneous Bronsted acid catalyst for l-(4-phenyl)-2,4-dihydropyrano[2,3c]pyrazole derivatives preparation

A new magnetic nanocatalyst based on the immobilization of tungstic acid onto new design robust, cost-effective, green, and scalable zirconium-L-aspartate amino acid metal-organic framework (MOF)-grafted L-(+)-tartaric acid stabilized magnetite nanoparticles (Fe3O4/tart-NPs) was synthesized by two successive solvo (hydro)-thermal methods. This catalyst was characterized by Fourier-transform infrared (FT-IR), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), Brunauer-Emmett-Teller (BET), Barrett-Joyner-Halenda (BJH), zeta potential, Thermogravimetry Analysis-Differential Thermal Analysis (TGA-DTA), and vibrating sample magnetometer (VSM) analyses. This catalyst is outstanding to prepare l-(4-phenyl)-2,4-dihydropyrano[2,3-c] pyrazole derivatives in aqueous media due to the open metal sites, high and steady proton conductivity in the zirconium-MOF, MIP-202(Zr), and MOF and also due to Bronsted acid properties of tungstic acid. This acidic catalyst can easily be extracted by an outward magnetic field after completion of the reaction without any deactivation or selectivity loss. The products were characterized by spectroscopic analysis (FT-IR, H-1-NMR, and C-13-NMR). The optimized reaction conditions and a possible reaction mechanism are outlined.
