AB  - Indocyanine green (ICG) is the FDA-approved fluorescent dye used for in vivo medical imaging, diagnostics, and photothermal therapy. However, this dye is easily degradable in the human vascular system, and therefore its stabilization is preferable. In this work, ICG molecules were stabilized by their adsorption on the surface of the L-methionine-capped Ag and Au nanoparticles (Ag and Au @LM NPs) in aqueous colloidal dispersions. The result is the formation of hybrid metal core/ICG shell NPs in colloidal dispersions. Additionally, colloidal dispersions were stabilized, indicating a double effect of ICG adsorption. The obtained hybrid NPs were studied experimentally (UV–Vis spectrophotometry, HRTEM, DLS, FTIR) and theoretically (DFT calculations). HRTEM revealed that the interplanar spacing between adjacent planes of NPs decreases after the dye adsorption. The results obtained from the DFT study confirmed the formation of a covalent bond between the oxygen from ICG dye SO3− group and metal NPs. Considering the characteristics of both components of the NPs/ICG hybrid system, the authors assume that this hybrid system can exhibit the synergistic effect that could lead to more successful theranostic treatment of cancer in nanomedicine.

AB  - We have synthesized 22 C-1 functionalized-N-aryl-1,2,3,4-tetrahydroisoquinoline derivatives showing biological activities towards cholinergic enzymes. Synthesis was performed using visible-light-promoted photo-redox chemistry, starting from a common intermediate, and the application of this synthetic methodology drastically simplified synthetic routes and purification of desired compounds. All synthesized derivates were divided into four groups based on the substituents in the C-1 position, and their inhibition potencies towards two cholinergic enzymes, acetyl- and butyrylcholinesterase were evaluated. Most potent derivatives were selected, and kinetic analysis was further carried out to obtain insights into the mechanisms of inhibition of these two enzymes. Further validation of the mode of inhibition of cholinergic enzymes by the two most potent THIQ compounds, 3c and 3i, was performed using fluorescence-quenching titration studies. Molecular docking studies further confirmed the proposed mechanism of enzymes’ inhibition. In silico predictions of physicochemical properties, pharmacokinetics, drug-likeness, and medicinal chemistry friendliness of the selected most potent derivatives were performed using Swiss ADME tool. This was followed by UPLC-assisted log P determination and in vitro BBB permeability studies performed in order to assess the potential of the synthesized compounds to pass the BBB.

AB  - Alzheimer's disease (AD), the most common form of dementia, is a progressive neurological disorder characterized by losing memory and other intellectual abilities that are serious enough to interfere with daily life. The disease is associated with loss of cholinergic neurons in the brain and the decreased level of ACh. In order to raise the ACh level in the brain the acetylcholinesterase (AChE) inhibitors have been applied as relevant drugs in the AD therapy. On the other hand, these inhibitors treat and improve only symptoms indicating necessity for new better therapies. One of them could be based on the inhibition of butyrylcholinesterase (BuChE) because of its increased activity during late stage of AD. Therefore, the BuChE inhibitors should be of great importance in therapy. 1,2,3,4-tetrahydroisoquinolines (THIQ) are a large group of natural and synthetic compounds which exert diverse biological activities against various infectious pathogens and neurodegenerative disorders. Due to these reasons, the THIQ have attracted a lot of attention in the scientific community which has resulted in the development of novel THIQ analogues with more potent biological activity. In this study the inhibitory potency of derivates of N-phenyl-1,2,3,4- tetrahydroisoquinoline, 178, 196 and 202, were investigated toward two cholinergic enzymes, AChE and BuChE. The performed screening tests pointed out the different inhibition potency of the selected compounds toward both enzymes which was related with their structures. The most potent compound has been 178 with IC50 values 1.30 μM and 2.50 μM toward AChE and BuChE, respectively. However, no selectivity was observed. Introducing F-atom in the para position of N-phenyl group of the compound 178, the compound 202 was obtained. In this way, the selectivity was increased towards acetylcholinesterase without significant influence on the IC50 value. However, introducing a methoxy groups in the position C3 and C4 of the tetrahydroisoquinoline’s ring of 202, the compound 196 with decreased inhibitory activity was obtained. IC50 value of 196 was one order of magnitude higher compared with compound 202. Based on the obtained results it is possible to conclude that introducing F atom in the para position of the phenyl ring lead to increased selectivity of the investigated compounds while introducing methoxy group in the position of C3 and C4 of tetrahydroisoquinoline ring leads to decrease of their inhibitory potency.

AB  - Visible light promoted photoredox catalyzed formation of α-amino radicals from cyclic tertiary amine compounds and their subsequent addition to Michael acceptors performed in flow conditions allowed access to a wide range of functionalized N-aryl-substituted tetrahydroisoquinolines (THIQs) and N-aryl-substituted tetrahydro-β-carbolines (THBCs). Visible light in conjunction with Ru(bpy)3Cl2 photocatalyst allowed the formation and high reactivities of α-amino radicals in flow conditions at room temperature. These reactions gave valuable products with high efficiencies; some previously unavailable reaction pathways photo or thermal reaction conditions; i.e. direct synthesis of 1-substituted (THBCs) via α-amino radical path were successfully realized in flow. The use of custom-made FEP tube microreactor proved to be the key to succesfull α-amino-radical formation and overall reaction performance in flow. Three types of light transparent custom-made microfluidic devices were tested, among them glass/silicon and FEP type reactor showed very good results in the conversion of tested compounds. Plausible reaction mechanism is proposed in accordance with known principles of photo activation of tertiary amines.

AB  - The study of the interactions between nanoparticles (NPs) and proteins has had a pivotal role in facilitating the understanding of biological effects and safe application of NPs after exposure to the physiological environment. Herein, for the first time, the interaction between L-methionine capped silver nanoparticles (AgMet), and bovine serum albumin (BSA) is investigated in order to predict the fate of AgMet after its contact with the most abundant blood transport protein. The detailed insights into the mechanism of interaction were achieved using different physicochemical techniques. The UV/Vis, TEM, and DLS were used for the characterization of the newly formed “entity”, while the kinetic and thermodynamic parameters were utilized to describe the adsorption process. Additionally, the fluorescence quenching and synchronous fluorescence studies enabled the prediction of the binding affinity and gave us insight into the influence of the adsorption on the conformation state of the BSA. According to the best of our knowledge, for the first time, we show that BSA can be used as an external stabilizer agent which is able to induce the peptization of previously agglomerated AgMet. We believe that the obtained results could contribute to further improvement of AgNPs’ performances as well as to the understanding of their in vivo behavior, which could contribute to their potential use in preclinical research studies.

AB  - Organophosphate-based pesticides have remarkably contributed to the agriculture industry, but their toxicity has a large negative impact on the environment as well as on the health of humans and other living organisms. Most of the methods developed to remedy the organophosphate pesticide toxicity are very time-consuming and are based on their adsorption onto different materials and/or their degradation to nontoxic species. In this study, detoxification of three structurally different organophosphate pesticides was investigated using an NU-1000 metal–organic framework. We showed that NU-1000 is an excellent agent for fast (average time ≤ 3 min) and effective removal of organophosphate pesticides with an aromatic heterocyclic moiety. In particular, superior detoxification of chlorpyrifos solution after NU-1000 treatment was achieved after only 1 min. The combination of experimental and computational methods revealed that the synergic effects of sorption and hydrolysis are responsible for the superior removal of CHP by NU-1000. The sorption process occurs on the Zr node (chemisorption) and pyrene linkers (physisorption) following pseudo-first-order kinetics during the first minute, and a pseudo-second-order model fits the entire time range. The multilayer adsorption of chlorpyrifos or its hydrolyzed product, 3,5,6-trichloro-2-pyridinol, takes place on a pyrene linker, whereas the aliphatic part of the molecule remains chemisorbed on the Zr node. Such unique synergy between induced sorption and hydrolysis of chlorpyrifos by NU-1000 results in its fast and effective removal with rapid detoxification in non-buffered solutions.

albumin (BSA) and methionine coated silver nanoparticles (AgNPs) under physiological like
conditions using fluorescence spectroscopy techniques. The quenching of BSA’s tryptophan
fluorescence has occurred at the concentration-dependent manner. The linear shape obtained for
Stern-Volmer plots and its larger slope at higher temperatures indicated mixed static and dynamic
quenching mechanisms. The values of quenching constants, Ksv and the bimolecular quenching rate
constants, kq, pointed out the existence of binding interactions between BSA and AgNPs. The
binding constants, K, with values around 1 × 104
 M-1, indicated low to moderate binding interaction
with one binding site. Determined thermodynamic parameters ΔHo < 0, ΔSo < 0 and ΔGo
 < 0 at different temperatures pointed out spontaneous processes, where hydrogen and van der Waals
interactions play a major role in the binding.

AB  - Intensive broiler chicken production involves different lighting regimes, which affects a natural cycle of secretion of melatonin, a hormone included in multiple physiological processes in a bird's body. This research aimed to determine the effects of dietary melatonin supplementation during the first two weeks of broiler chickens' life, bred under constant 24 h lighting, on their health and some hematological, biochemical, and production parameters. The study lasted 6 weeks. Three hundred and twenty 1-day chickens were divided into two groups (control - C and experimental - M), with four replications and 40 chickens in each replica. In the first two weeks (the first phase of the study), a continuous lighting mode 24L: 0D was applied. Group M was receiving a diet supplemented with 30 mg/kg synthetic melatonin only during the first phase. Group C had a diet without melatonin supplementation throughout the whole study. Melatonin addition had a statistically significant effect (P<0.01) on the mean values of body weight and daily weight gain at the end of the 1st, 2nd, 3rd, 4th, 5th, and 6th week. The chickens of the experimental group have had a significantly higher value of the European Production Efficiency Factor (EPEF) (P<0.05). The results presented in this paper indicate a direct benefit in stress relief in broilers and a value of the organism's antioxidant system promotion, manifested by improved production performance and fattening efficiency.

AB  - Organophosphate compounds (OPs) are highly acute toxic compounds used in agriculture production as pesticides. They bind to acetylcholinesterase leading to nerve paralysis and organ failure in humans. Hence, it has become mandatory on a global level to detect and remove organophosphate compounds from the environment. There are many conventional methods (nanoscale materials or sophisticated instruments) available to detect these compounds. However, these methods are time-consuming, expensive, and require an analytical laboratory with skilled staff. These constraints were the driving force for developing sensing platforms capable of detecting pesticides with excellent sensitivity. Metal-organic frameworks (MOFs) belong to porous coordination polymers fabricated from metal clusters/ions and multifunctional organic ligands. The tunable size and shape of pores, stable framework and the opportunity for desirable post-synthetic modifications classify them as promising candidates for potential use in detecting OPs at low nanomolar levels. This chapter will discuss the application of MOFs for the detection of selected organophosphate compounds. The special emphasis will be on MOF-based sensors, their sensitivity, selectivity, advantages and disadvantages in the OPs detection process. © 2022 Nova Science Publishers, Inc.

AB  - The goal of this work was to investigate the inhibitory potency of three derivates of 2- phenyl-1,2,3,4-tetrahydroisoquinoline (THIQ) with different substituents at C3 and C4 positions, namely 65P,71P and 66P, toward two cholinergic enzymes, acetyl and butyrylcholinesterase. The screening test showed that only compound 65P possesses inhibition activity higher than 50 % at 10 μM concentration toward both enzymes. The inhibition potency obtained at 10 μM of THIQ was correlated with differences in THIQ’s structures in order to predict the structure-activity relationship. It was found that the introduction of the methoxy group at positions C3 and C4 led to decreased inhibition potency, while the removing of fluorine atom from the benzene ring increases selectivity toward acetylcholinesterase. The IC50 value gained during the evaluation of inhibition activity of 65P indicated strong inhibition potency of this compound, while Hill’s coefficient ~ 1 indicated the non-existence of cooperativity and one binding site on both enzymes clearly indicating that THIQ could be promising therapeutic drugs in the treatment of Alzheimer’s disease.

AB  - Herein, we demonstrate that organic, single-electron oxidant in the presence of diarylprolinol silylether type catalyst serves as a tool for the transformation of electron-rich enamines to iminium ions. These iminium ions take part in a subsequent Michael-initiated ring-closure (MIRC) reaction with in situ present nucleophile giving rise to overall cyclopropanation reaction of saturated aldehydes. Stereodefined cyclopropanes are obtained in high yields and selectivities. This one-pot transformation represents the additional example of saturated aldehydes being used in the coupled one-pot processes. (Figure presented.).

The most active analyzed platinum complexes induced time-dependent growth inhibition of A375, HeLa, PANC-1, and MRC-5 cells. The best efficiency was achieved on HeLa and PANC-1 cells for Pt1, Pt2, and Pt3 at the highest concentration, while Pt1 was significantly more potent than cisplatin at a lower concentration. Additionally, a lower effect on normal cells was observed compared to cisplatin, which may indicate potentially fewer side effects of these complexes. Selected complexes induce reactive oxygen species and apoptosis on tumor cell lines. The most potent reversible acetylcholinesterase (AChE) inhibitors were Pt2, Pt4, and Pt5. Pt1 showed similar inhibitory potential toward AChE as cisplatin, but a different type of inhibition, which could contribute to lower neurotoxicity. Docking studies revealed that Pt2 and Pt4 were bound to the active gorge above the catalytic triad. In contrast, the other complexes were bound to the edge of the active gorge without impeding the approach to the catalytic triad. According to this, Pt1 represents a promising compound with potent anticancer properties, high selectivity, and low neurotoxicity.

AB  - In this study, the kinetics of bovine serum albumin (BSA) adsorption from aqueous solutions on the
methionine stabilized silver nanoparticles (AgNPs) was investigated. The influence of the parameters
such as contact time and BSA initial concentration on the adsorption capacity of AgNPs were tested.
By increasing the contact time up to 30 min, the percentage of adsorbed BSA was increased. After
this time, no changes were observed, indicating that the equilibrium state was reached. Investigation
of the initial concentration-effect showed that the percentage of BSA adsorption increased with
increasing BSA concentration until the available binding sites were saturated. After that, more BSA
molecules were left unadsorbed. To elucidate the adsorption kinetic, pseudo-first-order, pseudosecond-order, and intraparticle diffusion kinetic models were applied. The pseudo-second-order well
described the adsorption process and intraparticle diffusion model rate laws, and the intraparticle
diffusion is the sole rate-controlling step.

AB  - A new approach to drug design based on nanoparticles and related nanostructures for effective drug delivery, is of great importance in future medical treatment, especially for cancer therapy. Nanomaterials hold tremendous potential for increasing the efficiency of drug delivery, with a high degree of biocompatibility. Additionally, for biomedical applications, they must be biodegradable, have prolonged circulation half-life, not tend to aggregate or cause an inflammatory response in the body and to be cost-effective. The efficacy of such structures is highly dependent on their chemical properties as well as on shape, charge, size, surface modifications and loading method. Here we focused on the potential of using different kinds of nanoparticles and similar nanostructures loaded with various drugs in order to achieve specific targeting and controlled drug release. Thereby, computational modeling on NPs-based drug delivery could help in providing a better understanding of all parts of the delivery system. This review emphasizes recent advances in the usage of various types of nanoparticles and similar nanostructures for drug delivery, aiming to provide a critical review of less toxic and more effective treatment.

AB  - Three coordination compounds featuring different types of tetracopper(II) cores, namely [O ⊂ Cu4N(CH2CH2O)34(BOH)4][BF4]2 (1), [Cu4(μ4-H2edte)(μ5-H2edte)(sal)2]n·7nH2O, (H4edte = N,N,N′,N′-tetrakis(2-hydroxyethyl)ethylenediamine, H2sal = salicylic acid) (2), and [Cu4(μ3-Hbes)4(μ-hba)K(H2O)3]n, H3bes = N,N-bis(2-hydroxyethyl)-2-aminoethanesulfonic acid (3), were assayed for their potency to inhibit the acetyl (AChE) and butyrylcholinesterase (BuChE) enzymes aiming to test these compounds as potential dual inhibitors in the treatment of Alzheimer's disease. All the investigated compounds showed a strong inhibitory potency toward both enzymes with IC50 values in micromolar range of concentration; compound 1 displayed the most potent inhibitory behaviour toward both enzymes. The mechanism of the AChE and BuChE inhibition was examined by enzyme kinetic measurements. The obtained kinetic parameters, Vmax and Km indicated an uncompetitive type of inhibition of both enzymes by compound 1. For the other two compounds a non-competitive inhibition mode was observed. To get further insight into the mechanism of action and to elucidate binding modes in details we examined the interactions of 1–3 with acetylcholinesterase, using molecular docking approach. Grid based docking studies indicated that these compounds can bind to peripheral anionic site (PAS) of the AChE with Ki values in micromolar range. Moreover, blind docking revealed the capability of investigated compounds to bind to new allosteric site (i.e. binding site II) distinct from PAS. Showing that these Cu-based compounds can act as new allosteric inhibitors of AChE and identifying novel allosteric binding site on AChE represents a significant contribution toward the design of novel and more effective inhibitors of AChE. © 2020 Elsevier Inc.

AB  - Acetylcholinesterase (AChE) inhibitors are important in the treatment of neurodegenerative diseases. Two inhibitors,12-tungstosilicic acid (WSiA) and 12-tungstophosphoric acid (WPA), which have polyoxometalate(POM) type structure, have been shown to inhibit AChE activity in nM concentration. Circular dichroism andtryptophan fluorescence spectroscopy demonstrated that the AChE inhibition was not accompanied by significantchanges in the secondary structure of the enzyme. The molecular docking approach has revealed a newallosteric binding site, termed β-allosteric site (β-AS), which is considered responsible for the inhibition of AChEby POMs. To the best of our knowledge, this is the first study reporting a new allosteric site that is consideredresponsible for AChE inhibition by voluminous and negatively charged molecules such as POMs. The selectedPOMs were further subjected to genotoxicity testing using human peripheral blood cells as a model system. Itwas shown that WSiA and WPA induced a mild cytostatic but not genotoxic effects in human lymphocytes, whichindicates their potential to be used as medicinal drugs. The identification of non-toxic compounds capable ofbinding to an allosteric site that so far has not been considered responsible for enzyme inhibition could befundamental for the development of new drug design strategies and the discovery of more efficient AChEmodulators.

AB  - Abstract: This paper presents the study of the interaction between gold nanoparticles (AuNPs) and antitumor gold complexes, [Au(OH)2(bipy)][PF6], [Au(CH3COO)2(pydmb-H)], and [Au(bipydmb-H)(OH)][PF6], in order to estimate the possibility for metal complex tracking in cells using nanospectroscopy approach. Decrease of intensity of the surface plasmon absorption band at 524 nm and the appearance of a new broad band at ∼640 nm, followed by their red shift were observed in the presence of the complexes. TEM images showed that the average size and shape of AuNPs did not change after the addition of gold complexes. DLS and zeta potential measurements pointed out to the metal complex adsorption on the surface of AuNPs followed by flocculation process. In addition, kinetic studies indicated strong bond formation between these complexes and AuNPs. Accordingly, AuNPs/complex conjugates have the potential to be applied for the tracking of these metal complexes in the cells using nanospectroscopy approach. © 2019, Pleiades Publishing, Ltd.

AB  - Citrate-capped gold nanoparticles (AuNPs) were functionalized with three distinct antitumor gold(III) complexes, e.g., [Au(N,N)(OH)2][PF6], where (N,N)=2,2′-bipyridine; [Au(C,N)(AcO)2], where (C,N)=deprotonated 6-(1,1-dimethylbenzyl)-pyridine; [Au(C,N,N)(OH)][PF6], where (C,N,N)=deprotonated 6-(1,1-dimethylbenzyl)-2,2′-bipyridine, to assess the chance of tracking their subcellular distribution by atomic force microscopy (AFM), and surface enhanced Raman spectroscopy (SERS) techniques. An extensive physicochemical characterization of the formed conjugates was, thus, carried out by applying a variety of methods (density functional theory—DFT, UV/Vis spectrophotometry, AFM, Raman spectroscopy, and SERS). The resulting gold(III) complexes/AuNPs conjugates turned out to be pretty stable. Interestingly, they exhibited a dramatically increased resonance intensity in the Raman spectra induced by AuNPs. For testing the use of the functionalized AuNPs for biosensing, their distribution in the nuclear, cytosolic, and membrane cell fractions obtained from human lymphocytes was investigated by AFM and SERS. The conjugates were detected in the membrane and nuclear cell fractions but not in the cytosol. The AFM method confirmed that conjugates induced changes in the morphology and nanostructure of the membrane and nuclear fractions. The obtained results point out that the conjugates formed between AuNPs and gold(III) complexes may be used as a tool for tracking metallodrug distribution in the different cell fractions.

AB  - The present paper deals with investigation of the interaction between selected simple structure Au(iii) ([AuCl4]-, [AuCl2(dmso)2]+, [AuCl2(bipy)]+) and Pt(ii) ([PtCl2(dmso)2]) complexes with Na/K-ATPase as the target enzyme, using an experimental and theoretical approach. Reaction stoichiometries and binding constants for these enzyme/complex systems were determined, while kinetic measurements were used in order to reveal the type of inhibition. Based on the results obtained by quantum mechanical calculations (electrostatic surface potential (ESP), volume and surface of the complexes) the nature of the investigated complexes was characterized. By using the solvent accessible surface area (SASA) applied on specific inhibitory sites (ion channel and intracellular domains) the nature of these sites was described. Docking studies were used to determine the theoretical probability of the non-covalent metal binding site positions. Inhibition studies implied that all the investigated complexes decreased the activity of the enzyme while the kinetic analysis indicated an uncompetitive mode of inhibition for the selected complexes. Docking results suggested that the main inhibitory site of all these complexes is located in the ion translocation pathway on the extracellular side in the E2P enzyme conformation, similar to the case of cardiac glycosides, specific Na/K-ATPase inhibitors. Also, based on our knowledge, the hydrolyzed forms of [AuCl4]- and [PtCl2(dmso)2] complexes were investigated for the first time by theoretical calculations in this paper. Thereby, a new inhibitory site situated between the M2 and M4 helices was revealed. Binding in this site induces conformational changes in the enzyme domains and perturbs the E1-E2P conformational equilibrium, causing enzyme inhibition.

AB  - In vitro oxidative stress responses of two Keggin-type polyoxotungstates, 12- tungstosilicic (WSiA) and 12-tungstophosphoric acid (WPA), were investigated using rat synaptosomes as a model system. WSiA induced concentration-dependent increase in catalase activity, up to about 6 times compared to the control activity in untreated synaptosomes, and glutathione peroxidase was not significantly affected after WSiA treatment. On the contrary, WPA treatment resulted in the increase of glutathione peroxidase activity, while synaptosomal catalase was even reduced related to the control, at all investigated WPA concentrations. Both investigated polyoxotungstates did not significantly change malondialdehyde content in synaptosomal preparations. It could accordingly be concluded that WSiA and WPA probably induce reactive oxygen species generation, resulting in the activation of the antioxidant defense enzymes. However, these polyoxotungstates are not strong prooxidants being able to cause oxidative stress, and consequently synaptosomal membrane lipid damage.

AB  - Inhibition of acetylcholinesterase (AChE) is presented as a promising strategy in the treatment of Alzheimer disease providing inspiration for new discoveries and investigations less toxic and more effective potential anti Alzheimer drugs. In this paper, it demonstrated that the activity of acetylcholinesterase can be effectively inhibited by polyoxometalates (POMs), 12-tungstosilicic acid (WSiA) and 12-tungstophosphoric acid (WPA) without significant changes on the secondary structure of this enzyme. The obtained values of partition coefficient implicated on smooth pass of these POMs trough cell membrane and satisfied necessary criteria for the drugs used in the treatment of the central nervous system disease. Based on these obtained results it is possible to conclude that POM could represent new generation of potential anti Alzheimer drugs.
