Abstract
Extremely limited research exploring the photocatalytic potential of main group metals, such as aluminum, gallium, and tin, has been undertaken due to their weak light harvesting properties. This study reports the efficient transformation of sugars to 5-hydroxymethylfurfural (HMF) with high yield employing an original heterogeneous photocatalyst comprising a gallium(III) complex immobilized on an alumina support. Under visible light irradiation, the reaction rate of HMF formation is ~143 times higher than the equivalent thermal reaction performed in the absence of light. The turnover number (TON) of the heterogeneous gallium(III) photocatalyst was as high as 1500, which was ca. two orders of magnitude higher than the TON of the homogeneous gallium(III) system. It is proposed that photoirradiation significantly enhances the Lewis acidity of the catalyst by forming a semi-coordination state between gallium(III) and N-donor ligands, enabling the increased interaction of reactant sugar molecules with gallium(III) active sites. Consistent with this, the photoresponsive coordination of the gallium(III) complex and the abstraction of the hydroxy group by the metal under irradiation with visible light is observed by NMR spectroscopy for the first time. These findings demonstrate that efficient photocatalysts derived from the main group elements can facilitate biomass conversion using visible light.

Abstract
Aim: Amoxapine (AMX) has been reported to be metabolized by CYP3A4 and CYP2D6. Naringin (NG) has been reported to inhibit CYP enzymes. Therefore, the current work was designed to develop AMX solid lipid nanoparticles (AMX-SLNs) and NG-SLNs for better therapeutic performance. Materials & methods: AMX-SLNs and NG-SLNs were prepared and characterized. AMX and NG interactions with CYP450s were studied with molecular docking to rationalize the effectiveness of the combination. Results: AMX-SLNs and NG-SLNs showed nanometric size with a sustained in vitro drug-release profile. NG showed a higher predicted binding affinity for CYP3A4 and CYP2D6, suggesting the potential for inhibition. Conclusion: The developed formulations were thoroughly characterized along with molecular docking data indicating promising AMX and NG combinations that may show good therapeutic activity.

Abstract
The possibility of application of chitosan-modified zeolite as sorbent for Cu(II), Zn(II), Mn(II), and Fe(III) ions and their mixtures in the presence of N-(1,2-dicarboxyethyl)-D,L-aspartic acid, IDHA) under different experimental conditions were investigated. Chitosan-modified zeolite belongs to the group of biodegradable complexing agents used in fertilizer production. NaP1CS as a carrier forms a barrier to the spontaneous release of the fertilizer into soil. The obtained materials were characterized by Fourier transform infrared spectroscopy (FTIR); surface area determination (ASAP); scanning electron microscopy (SEM-EDS); X-ray fluorescence (XRF); X-ray diffraction (XRD); and carbon, hydrogen, and nitrogen (CHN), as well as thermogravimetric (TGA) methods. The concentrations of Cu(II), Zn(II), Mn(II), and Fe(III) complexes with IDHA varied from 5-20 mg/dm3 for Cu(II), 10-40 mg/dm3 for Fe(III), 20-80 mg/dm3 for Mn(II), and 10-40 mg/dm3 for Zn(II), respectively; pH value (3-6), time (1-120 min), and temperature (293-333 K) on the sorption efficiency were tested. The Langmuir, Freundlich, Dubinin-Radushkevich, and Temkin adsorption models were applied to describe experimental data. The pH 5 proved to be appropriate for adsorption. The pseudo-second order and Langmuir models were consistent with the experimental data. The thermodynamic parameters indicate that adsorption is spontaneous and endothermic. The highest desorption percentage was achieved using the HCl solution, therefore, proving that method can be used to design slow-release fertilizers.

Abstract
In this study, a new alkylaminophenol compound was synthesized and characterized by spectroscopic techniques (FT-IR, NMR, UV). The optimized molecular geometry and the vibrational wavenumbers were calculated using density functional theory (DFT) B3LYP/WB97XD and HF methods with 6-311++ G([Formula: see text], [Formula: see text]) basis set. Thus, theoretical data were compared within themselves before comparing with experimental data. The detailed interpretation of the vibrational spectra has been carried out by VEDA program. 1H-NMR and [Formula: see text]C-NMR chemical shifts of the compound were calculated using GIAO/IEFPCM method in CDCl3. Using time-dependent (TD-DFT) approach electronic properties such as HOMO and LUMO energies, the electronic spectrum of the title compound has been studied and reported. Stability of the molecule arising from hyper conjugative interactions, charge delocalization has been analyzed using natural bond orbital (NBO) analysis. Linear polarizability, anisotropic linear polarizability and hyperpolarizability values of the title compound were found to be higher than the values of the pNA compound that are used as a standard substance in the NLO analysis. Molecular electrostatic potential (MEP), the thermodynamic properties (heat capacity, entropy and enthalpy) were calculated. Also, to investigate the biological properties of the title compound, molecular docking was done with DNA(PDB ID: 414D). It has been observed that the effective interaction is hydrogen bonds.

Abstract
Background: :
Styrylquinolines are characteristic fully aromatic compounds with flat,
rather lipophilic structures. The first reports on their synthesis and biological activity were published
roughly a century ago. However, their low selectivity, unfavorable toxicity and problems
with their mechanism of action significantly hampered their development. As a result, they have
been abandoned for most of the time since they were discovered.
Objective: :
Their renaissance was observed by the antiretroviral activity of several styrylquinoline
derivatives that have been reported to be HIV integrase inhibitors. Subsequently, other activities
such as their antifungal and anticancer abilities have also been revisited.
Methods:
In the present review, the spectrum of the activity of styrylquinolines and their use in
drug design is presented and analyzed.
Results:
New properties and applications that were reported recently have re-established
styrylquinolines within medicinal and material chemistry. The considerable increase in the number
of published papers regarding their activity spectrum will ensure further discoveries in the field.
Conclusions:
Styrylquinolines have earned a much stronger position in medicinal chemistry due to
the discovery of their new activities, profound mechanisms of action and as drug candidates in
clinical trials.

Abstract
A Zr(iv) based luminescent metal-organic framework (MOF; 1) was synthesized by a solvothermal method using a mixture of ZrCl4, quinoline-2,6-dicarboxylic acid (H2QDA) ligand and trifluoroacetic acid (modulator) having a 1 : 1 : 10 molar ratio in N,N-dimethylformamide (DMF). For activation, the methanol-exchanged sample was heated under high vacuum at 120 °C for 1 day. Different techniques like X-ray powder diffraction (XRPD), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) spectroscopy and energy dispersive X-ray (EDX) analysis were applied to fully characterize 1. The activated form of 1 (called 1') has the formula [Zr6O6(OH)2(CF3COO)2(C11H5NO4)4(H2O)4]. It exhibited quick response and great selectivity for the fluorimetric sensing of 4-nitrophenol (4-NP) in acetonitrile and Fe3+ ions in water. The probe maintained its high selectivity for 4-NP and Fe3+ ions even in the presence of potentially intrusive nitroaromatics and metal ions, respectively. The detection limits for 4-NP and Fe3+ were found to be 1.40 ppt and 0.71 ppb, respectively. These values are the lowest among the existing MOF probes for Fe3+ and 4-NP. The electron and energy transfer processes along with the electrostatic interactions of 4-NP with the MOF can be the possible reasons for the selectivity for 4-NP. The fluorescence resonance energy transfer (FRET) process can be the major reason behind the quenching mechanism for Fe3+ ions. The recyclability test indicates that 1' is a promising probe for the long-term detection of 4-NP and Fe3+ ions.

Abstract
Starch and chitosan are widely used for preparation of edible films that are of great interest in food preservation. This work was aimed to analyze the relationship between structural and physical properties of edible films based on a mixture of chitosan and modified starches. In addition, films were tested for antimicrobial activity against Listeria innocua. Films were prepared by the casting method using chitosan (CT), waxy (WS), oxidized (OS) and acetylated (AS) corn starches and their mixtures. The CT-starches films showed improved barrier and mechanical properties as compared with those made from individual components, CT-OS film presented the lowest thickness (74 ± 7 µm), water content (11.53% ± 0.85%, w/w), solubility (26.77% ± 1.40%, w/v) and water vapor permeability ((1.18 ± 0.48) × 10−9 g·s−1·m−1·Pa−1). This film showed low hardness (2.30 ± 0.19 MPa), low surface roughness (Rq = 3.20 ± 0.41 nm) and was the most elastic (Young’s modulus = 0.11 ± 0.06 GPa). In addition, films made from CT-starches mixtures reduced CT antimicrobial activity against L. innocua, depending on the type of modified starch. This was attributed to interactions between acetyl groups of AS with the carbonyl and amino groups of CT, leaving CT with less positive charge. Interaction of the pyranose ring of OS with CT led to increased OH groups that upon interaction with amino groups, decreased the positive charge of CT, and this effect is responsible for the reduced antimicrobial activity. It was found that the type of starch modification influenced interactions with chitosan, leading to different films properties.

Abstract
In the presented study, N-{[(5S)-3-(2-fluoro-4'-{[(1H-1,2,3-triazol-5-ylmethyl)amino]methyl}biphenyl-4-yl)-2-oxo-1,3-oxazolidin-5-yl]methyl}acetamide (radezolid) was synthesized and characterized using FT-IR, Raman, ECD and NMR. The aim of this work was to assess the possibility of applying classical spectral methods such as FT-IR, Raman, ECD and NMR spectroscopy for studies on the identification and optical purity of radezolid. The experimental interpretation of FT-IR and Raman spectra of radezolid was conducted in combination with theoretical studies. Density functional theory (DFT) with the B3LYP hybrid functional was used for obtaining radezolid spectra. Full identification was carried out by COSY, 1H {13C} HSQC and 1H {13C} HMBC experiments. The experimental NMR chemical shifts and spin-spin coupling constants were compared with theoretical calculations using the DFT method and B3LYP functional employing the 6-311++G(d,p) basis set and the solvent polarizable continuum model (PCM). The experimental ECD spectra of synthesized radezolid were compared with experimental spectra of the reference standard of radezolid. Theoretical calculations enabled us to conduct HOMO and LUMO analysis and molecular electrostatic potential maps were used to determine the active sites of microbiologically active form of radezolid enantiomer. The relationship between results of ab initio calculations and knowledge about chemical-biological properties of S-radezolid and other oxazolidinone derivatives are also discussed.
