AB  - The durability of enzymes in harsh conditions can be enhanced by immobilization within metal-organic frameworks(MOFs) via a process called biomimetic mineralisation. Zeolitic imidazolate framework-8 (ZIF-8) is widely used as aprotective coating to encapsulate proteins. The formation of nucleation centres and further biocomposite particlegrowth is entirely governed by the pure electrostatic interactions between the protein’s surface and positively chargedZn(II) metal ions. It was previously shown that enhancing these electrostatic interactions by a chemical modificationof surface amino acid residues can lead to a rapid biocomposite formation. However, a chemical modification ofcarbohydrate components by periodate oxidation for glycoproteins can serve as an alternative strategy. In the presentstudy, an industrially important enzyme glucose oxidase (GOx) was selected as a model system. Periodate oxidationof GOx by 2.5 mM sodium periodate increased negative charge on the enzyme molecule. Biomineralizationexperiments with oxidized GOx resulted in higher specific activity, effectiveness factor, and higher thermostability ofthe ZIF-8 biocomposites.

AB  - Metal-organic frameworks (MOFs) are a class of materials well-known for their high degree of crystallinity andultrahigh porosity. Modular synthesis from organic linkers and metal nodes allows for precise control of structure,pore size and chemical functionality of MOFs. Recently, MOFs have been explored for their potential to form novelbiocomposites with proteins by a process termed biomimetic mineralization. These novel MOF biocomposites showgreat promise for application to industrial biocatalysis where strategies for enhancing enzyme stability are ofsignificant interest. The protective capacity and applications of biomimetically mineralized biomacromolecule zeoliticimidazolate framework (ZIF-8) composites are likely dependent on the charge of the biomolecule and the topologyof the mineralized ZIF-8 coating. Herein, we identify conditions to reliably yield the porous periodate oxidizedhorseradish peroxidase@ZIF-8 sodalite topology biocomposite in preference to other more dense phases.

AB  - Metal-organic frameworks (MOFs) are a class of inorganic materials with potential application in gas adsorption, biosensitization, biocatalysis, and drug delivery [1]. Zeolitic imidazolate frame-works (ZIFs) are a subclass of MOFs, particularly suitable for enzyme immobilization by biomi-metic mineralization [1]. ZIF-8 consisting of tetrahedral Zn(II) ions bridged via 2-methylimidazole ligands (mIM) is most commonly used for this purpose. However, the topology and morphology of ZIF-8 crystals vary depending on the experimental synthesis conditions. In addition, during the process of biomimetic mineralization, the biocomposite composed of the enzyme immobilized in ZIF-8 is washed with buffers and detergents to remove excess of an adsorbed enzyme, which can lead to the chemical transformation of the surface and undesirable release of the enzyme. There-fore, the influence of anion nature on the topology and morphology of ZIF-8 was investigated in this work, and the stability of ZIF-8 crystallites was tested in acetate buffer (0.1 M; pH = 5.5) and sodium dodecyl sulfate solution (ω = 10%). Crystal morphology was monitored by scanning elec-tron microscopy, while topology was determined using powder X-ray diffraction.

AB  - The substituent and solvent effect on intramolecular charge transfer (ICT) of twelve monocarbohydrazones (mCHs) were studied using experimental and theoretical methodology. The effects of specific and non-specific solvent-solute interactions on the UV-Vis absorption maxima shifts were evaluated using linear free energy relationships (LFERs) principles, i.e. using the Kamlet-Taft and Catalan models. Linear free energy relationships in the form of single substituent parameter equation (SSP) was used to analyze substituent effect on UV-Vis, NMR and pK(a) change. According to crystallographic data and quantum chemical calculations, the trans (E) form was found to be more stable. A photochromism of compounds with 2-hydroxyphenyl and 2-pyridylimino groups substituted at imine carbon atom results in E/Z isomerization due to creation of intermolecular hydrogen bond in E and Z form, respectively. Multiple stage mass spectrometry (MS-MSn) analysis was applied to define main fragmentation pathways. Furthermore, the experimental findings were interpreted with the aid of ab initio MP2/6-311 G(d,p) and time-dependent density functional (TD-DFT) methods. TD-DFT calculations were performed to quantify the efficiency of intramolecular charge transfer (ICT) with the aid of the charge-transfer distance (DCT) and the amount of transferred charge (QCT) calculation. It was found that both substituents and solvents influence electron density shift i.e. extent of conjugation, and affect ICT character in the course of excitation.

AB  - Due to the rise of microbial strains resistant to conventional therapies, there is an urgent need for finding the new antimicrobial chemotypes. Heterocyclic compounds such as thiocarbohydrazones (TCHs) are able to interact with many metalloenzymes essential for microbes, while sulfur atom increases lipophilicity which is generally positively correlated with potency. In this paper, we report antibacterial and antifungal activity of twenty-two TCHs toward eight bacterial and three fungal strains. Furthermore, three alignment independent 3D QSAR models based on descriptors derived from molecular interaction fields (MIFs) are developed in order to rationalize structure-activity relationships for activities of TCHs toward S. aureus, P. aeruginosa and C. albicans. Several structural fragments important for biological activity are recognized in each model, and structural modifications which could lead to increased potency are suggested. Designed structures will be synthesized accordingly and tested toward the same microbial strains in order to obtain more potent derivatives.

The electrophilic f(-) and nucleophilic f(+) Fukui functions are well adapted to find the electrophile and nucleophile centres in the molecules. Both (1,3-selenazol-2-yl)- and (1,3-thiazol-2-yl) hydrazone Co(III) complexes showed potent antimicrobial and antioxidant activity. A significant difference among them was a smaller cytotoxicity of selenium compounds.

AB  - A comparative study of antitumor activity of mono- and bis-quinoline based (thio) carbohydrazones was investigated by a series of tests on two human malignant cell lines: acute monocytic leukemia (THP-1) and pancreatic adenocarcinoma cancer stem cells (AsPC-1). Thiocarbohydrazones (TCHs) revealed superior pro-apoptotic activity over carbohydrazones (CHs) on both tested cell phenotypes, also displaying multi-target profile activities. Programmed cell death triggered by TCHs was partially caspase-dependent, mainly caspase-8 related. Activity against cancer stem cells (CSCs) was evaluated on 2D monolayers and 3D spheroidal models, where two out of three tested bis-TCHs successfully stimulated apoptosis accompanied by a reduction in size of treated spheres. Additionally, all bis-TCHs induced significant decrease in percentage of CD44-expressing AsPC-1 cells that indicate on their ability to induce reprogramming of CSC phenotype. Current results highly support further assessment of bis-TCHs in order to specify their specific targets in cancer cells and particularly in the CSCs subpopulation.

AB  - Co(III) complex with a 2-hydrazonylthiazole ligand was synthesized and characterized by single-crystal X-ray diffraction. In the inner sphere of the complex, two monoionic ligands are coordinated tridentately forming octahedral geometry around Co(III). Activity of the complex was investigated on MCF-7 breast cancer cell line, with cisplatin (CDDP) as a reference compound. Results showed that after 24-h incubation, Co(III) complex revealed stronger cytotoxic activity compared to CDDP. Treatment of MCF-7 3-D cell model with the complex at 10M concentration achieved complete suppression of spheroid growth in almost the same extent as at 100M. In combination treatments on MCF-7 spheroids, the complex acted synergistically with CDDP, while additive interaction type was achieved when the complex was applied together with paclitaxel.

AB  - A new Ni(II) complex, [Ni(L)(H2O)] (1), with diethyl 3,3'-(2,2'-(1,1'-(pyridine-2,6-diyl) bis(ethan-1-yl-1-ylidene)) bis(hydrazin-1-yl-2-ylidene)) bis(3-oxopropanoate) ligand (H2L) was synthesized as a potential chemotherapeutic agent. Polidentate ligand was coordinated to Ni(II) NNN-tridentately, in dianionic form, while monodentate water coordination completed square-planar geometry around metal. Structure in the solution was determined by NMR spectroscopy and the same coordination mode was observed in the solid state using IR spectroscopy and further verified by DFT calculations and electrochemical studies. Thermal stability of 1 was determined in both air and nitrogen atmosphere. Anticancer activity of 1 was investigated on acute monocytic leukemia (THP-1) and pancreatic adenocarcinoma (AsPC-1) cell lines. On THP-1 cells 1 induced powerful apoptotic response (ED50 = 10 +/- 3 mu M), which was revealed to be only partially caspase-dependent, with activation of caspase-8 as the dominant course. This suggested that experimentally validated covalent binding of 1 to DNA is not the only mechanism responsible for programmed cell death. This was supported with experiments on AsPC-1 cells. Although treatment of those cells with 1 resulted in poor apoptotic response, cell cycle changes showed concentration-dependent shifts indicating a dual mechanism of activity. This study also reviews the results of preliminary biological screening, which demonstrates that 1 displays a unique pattern of anticancer activity with at least two mechanisms involved.

AB  - A new Zn(II)-based potential chemotherapeutic agent was synthesized from the ligand 2-quinolinecarboxaldehyde selenosemicarbazone (Hqasesc). Single crystal X-ray diffraction analysis showed that the Zn(II) complex consists of a cation [Zn(Hqasesc)(2)](2+), two perchlorate anions and one ethanol solvent molecule. The interaction of calf thymus (CT) DNA and human serum albumin (HSA) with the Zn(II) complex was explored using absorption and emission spectral methods, and also has been supported by molecular docking studies. The complex has more affinity to minor DNA groove than major, with no significant intercalation. The HSA interaction studies of the complex revealed the quenching of the intrinsic fluorescence of the HSA through a static quenching mechanism. The antitumor activity of the ligand and the complex against pancreatic adenocarcinoma cell line (AsPC-1) and acute monocytic leukemia (THP-1) cells was evaluated. Both compounds are strong concentration-dependent apoptosis inducers in THP-1 cells. While Hqasesc in AsPC-1 cells induces apoptosis only at the highest concentration, treatment with the Zn complex shows a concentration-dependent apoptotic response, where the treated cells are arrested in the G1-to-S phase accompanied with extensive activation of caspase-8 and -9. These results indicate that the ligand and Zn(II) complex display cell phenotype specific activity.

AB  - Novel Pd(II) complex with N-heteroaromatic Schiff base ligand, derived from 8-quinolinecarboxaldehyde (q8a) and ethyl hydrazinoacetate (haOEt), was synthesized and characterized by analytical and spectroscopy methods. The structure of novel complex, as well as structures of its quinoline and pyridine analogues, was optimized by density functional theory calculations, and theoretical data show good agreement with experimental results. A cytotoxic action of the complexes was evaluated on cultures of human promyelocytic leukemia (HL-60), human glioma (U251), rat glioma (C6), and mouse fibrosarcoma (L929) cell lines. Among investigated compounds, only complexes with quinoline-based ligands reduce the cell numbers in a dose-dependent manner in investigated cell lines. The observed cytotoxic effect of two isomeric quinoline-based complexes is predominantly mediated through the induction of apoptotic cell death in HL-60 cell line. The cytotoxicity of most efficient novel Pd(II) complex is comparable to the activity of cisplatin, in all cell lines investigated.

AB  - Condensation derivatives of ethyl hydrazinoacetate with 2-formylpyridine and quinoline-2-carboxaldehyde were synthesized. Pd(II), Pt(II) and Cd(II) complexes with the 2-formylpyridine derivative and a Cd(II) complex with the quinoline-2-carboxaldehyde derivative were synthesized and characterized by spectroscopic techniques. In the complexes, both ligands are coordinated in neutral NN bidentate modes, while the remaining two coordination sites are occupied by chloride. All compounds showed biological activity when tested against Escherichia coli, Bacillus subtilis and Staphylococcus aureus.
