Design, synthesis and biological evaluation of iridium(III) complexes as potential antitumor agents

Cisplatin and its analogs have been used for the treatment of various cancers, but their serious side effect has limited clinical application. Presently, scientists are developing other metal drugs as an alternative of cisplatin. In this paper, three new iridium(III) complexes [Ir(ppy)(2)(adppz)](PF6) (adppz = 7-aminodipyrido[3,2-alpha:2′,3′-c] phenazine; ppy = 2-phenylpyridine 1), [Ir(bzq)(2)(adppz)](PF6) (bzq = benzo[h]quinolone 2) and [Ir(piq)(2)(adppz)](PF6) (piq = 1-phenylisoquinoline 3) were synthesized and characterized. The complexes can effectively inhibit the cell colonies. The cytotoxicity in vitro of the complexes against A549, HepG2, SGC-7901, BEL-7402 and normal NIH3T3 cells was evaluated by 3-(4,5-dimethylthiazole)-2,5-diphenyltetraazolium bromide (MTT) methods. The intracellular reactive oxygen species (ROS) levels and Ca2+ concentrations were assayed. The mitochondrial membrane potential, a release of cytochrome c and the expression of B-cell lymphoma/leukemia-2 (Bcl-2) family protein have been investigated. The data reveal that the complexes 1-3 can effectively inhibit the cell proliferation in A549 cells with low IC50 value of 3.2 +/- 0.4 mu M, 4.8 +/- 0.5 and 1.2 +/- 0.2 mu M, respectively. The antitumor in vivo shows that complex 3 can inhibit tumor growth with an inhibitory rate of 76.34%. The studies on the mechanism indicate that these complexes cause apoptosis in A549 cell via a ROS-mediated lysosomal-mitochondrial dysfunction pathway. In addition, the interaction of the complexes with BSA was explored.

Effect of chain length and counter-ion on interaction study of mixed micellar system of isoquinoline-based surface active ionic liquid and cationic surfactants in aqueous medium

In the present study, we have investigated the effect of nature of surfactant, chain length and counter-ion on the mixed micellization behaviour ofvarious cationic surfactants, tetradecyltrimethylammonium bromide (TTAB), dodecyltrimethylammonium chloride (DTAC) and cationic gemini surfactant, bis(tetradecyldimethylammonium)hexane dibromide(C14-6-C14,2Br) with surface active ionic liquid (SAIL) tetradecylisoquinolinium bromide [C(14)iQuin][Br]. The interactions and mixed micellar behaviour of cationic surfactants and SAIL in aqueous medium have been studied by employing conductometry measurements and H-1 NMR technique. The critical micelle concentration (cmc) and various thermodynamic parameters like standard Gibbs free energy of micellization (Delta G(m)(0)), change in standard enthalpy (Delta H-m(0)) and entropy of micellization (Delta S-m(0)) have been calculated from conductometry measurements. Mixed micellar parameters such as ideal cmc (cmc*), micellar mole fraction (X-1(m)), micellar interaction parameter (beta(m)) and activity coefficients, (f(1) and f(2)) have been evaluated by applying Clint, Rubingh and Motomura theoretical models. Synergistic and non-ideal interactions have been found between SAIL and surfactants. Graphical abstract

Phenotypic and genotypic methods for identification of slime layer production, efflux pump activity, and antimicrobial resistance genes as potential causes of the antimicrobial resistance of some mastitis pathogens from farms in Menoufia, Egypt

Mastitis caused by multi- or pan-drug resistant bacteria is a growing health concern. A total of 110 milk samples were collected: Staphylococcus aureus, Streptococcus agalactiae, Streptococcus dysgalactiae, Enterococcus faecalis, and Escherichia coli were present in 54/110 (49.09%), 37/110 (33.63%), 25/110 (22.72%), 7/110 (6.36%), and 50/110 (45.45%) samples, respectively. A total of 20 methicillin-resistant S. aureus (MRSA) isolates, 19 Streptococcus sp. isolates, and 15 E. coli isolates were selected, and 100% were positive for (coagulase and hemolysins), streptokinase, and hemolytic activity, respectively. A number of 11 E. coli isolates were serotyped, and the serotypes were: O26, O55, O111, O119, O124, O125, O127, and O158. The antimicrobial resistance index ranges for MRSA, Streptococcus sp., and E. coli were 0.49-0.83, 0.39-0.83, and 0.56-1, respectively. The most effective antimicrobials on Gram-positive isolates were cephradine, ciprofloxacin, doxycycline, norfloxacin, and vancomycin, while doxycycline and norfloxacin were effective on E. coli serotypes. All of the selected isolates exhibited slime layer production. The efflux pumps of the 12 MRSA, 12 Streptococcus sp., and 11 E. coli isolates exhibited activity with ethidium bromide concentrations of 1, 1.5, and 0.5 mu g/ml, respectively. There was a simultaneous antimicrobial activity of the efflux pump inhibitor chlorpromazine with amoxicillin/clavulanic acid, erythromycin, and oxacillin, to which the isolates were resistant. The 12 MRSA isolates harboured the methicillin resistance genes mec(A,A1, and A2), mecA1, and mecC at frequencies of 9/12 (75%), 9/12 (75%), and 8/12 (66.7%), respectively, and the penicillin resistance gene BlaZ was present at a frequency of 5/12 (41.7%). The distributions of erm(A), erm(B), erm(C), erm(F), erm(G), and erm(Q) were 8/12 (66.7%), 5/12 (41.7%), 12/12 (100%), 2/12 (16.7%), 0/12 (0.0%), and 8/12 (66.7%), respectively. The 12 Streptococcus sp. isolates harboured mec(A, A1, and A2), mecA1, mecC, and blaZ at rates of 4/12 (33.33%), 4/12 (33.33%), 5/12 (41.7%), and 4/12 (33.33%), respectively. The frequencies of erm(A) and erm(F) were 4/12 (33.33%), and 9/12 (75%), respectively. The 11 E. coli isolates harboured the extended-spectrum beta-lactamases integrase1, integrase2, blaCTX-M, blaCTX-M-1, and blaTEM at frequencies of 10/11 (90.90%), 11/11 (100%), 9/11 (81.81%), 6/11 (54.54%), and 10/11 (90.90%), respectively. Moreover, the frequencies of erm(A), erm(B), erm(C), erm(F), erm(G), and erm(Q) were 7/11 (63.63%), 4/11 (36.36%), 4/11 (36.36%), 5/11 (45.45%), 10/11 (90.90%), and 10/11 (90.90%), respectively.

Boosting hydrogen and oxygen evolution reactions on electrodeposited nickel electrodes via simultaneous mesoporosity, magnetohydrodynamics and high gradient magnetic force

Here we report on hydrogen and oxygen evolution on electrodeposited nickel electrodes enhanced by mesoporosity and magnetics. Mesoporous and bulk Ni films were electrodeposited from simple sulphate solutions with and without lyotropic liquid crystal (LLC) templates formed by the cationic surfactant cetyltrimethylammonium bromide (CTAB). The mesoporous microstructure increases the electrochemical surface area 20-fold relative to the bulk films. In the first instance, this improves the hydrogen (HER) and oxygen (OER) evolution reaction performances significantly on mesoporous (MP) Ni electrodes, but only to a limited degree owing to the substantial surface deactivation of nickel and surface coverage during water splitting in alkaline media. The water splitting process is further enhanced by magnetisation on both bulk and mesoporous Ni electrodes, as evidenced by the reduced onset potential, over-potential, and Tafel slope, as well as by the increased exchange current density; these effects are stronger in the perpendicular magnetisation direction owing to the ordinary magnetohydrodynamics (MHD) effect. However, MP-Ni electrodes exhibit extraordinary performance with respect to ordinary MHD, which was attributed to the creation of high-gradient magnetic force (HGMF). The maximum HER performance of the magnetised MP-Ni electrodes demonstrates a remarkable improvement, e.g. eta(OER) = 340.0 mV, which is comparable with more complex nanomaterials, e.g. hybrid metal oxides, whereas their maximum OER performance, e.g. eta(OER) = 296.0 mV, comes very close to those of noble metal electrodes, e.g. Ru2O. Our calculations based on a simple nanotubular nickel structure show that MP-Ni creates magnetic gradients of the order of 10(7) T m(-1). This magnitude of magnetic force is sufficient to promote effective attractive/repulsive forces on ions and gas bubbles as well as the dissociation of diamagnetic water molecules, enhancing the HER and OER during water splitting during electrolysis. Our present remarkably enhanced water electrolysis device, achieved using magnetized mesoporous nickel, represents a very sophisticated and low-cost electrode material choice to replace costly electrocatalysts in water splitting.

Thermodynamic Performance Evaluation of a Solar Parabolic Dish Assisted Multigeneration System

The concentration ratio of the parabolic dish solar collector (PDSC) is considered to be one of the highest among the concentrated solar power technologies (CSPs); therefore, such system is capable of generating more heat rate. The present paper focuses on the integration of the PDSC with the combined cycle (gas cycle as the toping cycle and steam cycle as the bottoming cycle) along with the utilization of waste heat from the power cycle to drive the single effect lithium bromide/water absorption cycle. Molten salt is used as a heat transfer fluid in the solar collector. The engineering equation solver (EES) is employed for the mathematical modeling and simulation of the solar integrated system. The various operating parameters (beam radiation, inlet and ambient temperatures of heat transfer fluid, mass flow rate of heat transfer fluid, evaporator temperature, and generator temperature) are varied to analyze their influence on the performance parameters (power output, overall energetic and exergetic efficiencies, outlet temperature of the receiver, and as coefficient of performance (COP) and exergy efficiencies) of the integrated system. The results show that the overall energy and exergy efficiencies are observed to be 39.9% and 42.95% at ambient temperature of 27 degrees C and solar irradiance of 1000 W/m(2). The outlet temperature of the receiver is noticed to decrease from 1008 K to 528 K for an increase in the mass flow rate from 0.01 to 0.05 kg/s. The efficiency rate of the power plant is 38%, whereas COP of single effect absorption system is 0.84, and it will decrease from 0.87 to 0.79. However, the evaporator load is decreased to approximately 9.7% by increasing the generator temperature from 47 degrees C to 107 degrees C.

Topo I inhibition, DNA photocleavage, Molecular docking and cytotoxicities of two new phenanthroline-based ruthenium complexes

Two ruthenium complexes containing a new phenanthroline-based ligand pai (pai = 2-(5-(1, 10- phenanthroline))-1H-acenaphtho[1 ‘,2 ‘:4,5]imidazole) were synthesized and characterized. Two ruthenium complexes were found to cleave DNA under irradiation, interact with CT-DNA by intercalation. Furthermore, DNA topoisomerase inhibition experiments indicated that complex 2 exhibited higher topoisomerase I inhibition activity (IC50 = 10 mu M) than complex 1 (IC50 = 40 mu M). Molecular modeling studies revealed that complex 2 stabilized Top1cc complex via pi-pi interaction and the formation of hydrogen bond. The cytotoxicity of complexes 1 and 2 against Eca-109 and A549 cells was also evaluate by MTT method, indicating that complex 2 exhibited good anticancer activity against Eca-109 cells (IC50 = 17.23 +/- 0.22 mu M), but two ruthenium complexes displayed weak anticancer activity against A549 cells.

The inhibition of enterovirus 71 induced apoptosis by Durvillaea antarctica through P53 and STAT1 signaling pathway

The infection of enterovirus 71 (EV71) resulted in hand, foot, and mouth disease and may lead to severe nervous system damage and even fatalities. There are no effective drugs to treat the EV71 virus and it is crucial to find novel drugs against it. Polysaccharide isolated from Durvillaea antarctica green algae has an antiviral effect. In this study, D. antarctica polysaccharide (DAPP) inhibited the infection of EV71 was demonstrated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), reverse transcription polymerase chain reaction, flow cytometry, and western blot. MTT assay showed that DAPP had no toxicity on Vero cells at the concentration 250 mu g/ml. Furthermore, DAPP significantly reduced the RNA level of EV71 in a dose-dependent manner. Moreover, DAPP inhibited the Vero cells apoptosis induced by EV71 via the P53 signaling pathway. Meanwhile, the expression of signal transducer and activator of transcription 1 and mammalian target of rapamycin were increased and the proinflammatory cytokines were significantly inhibited by DAPP. Taken together, these results suggested that DAPP could be a potential pharmaceutical against the infection of EV71 virus.

The aggregation and micellization of ionic surfactants in aqueous solution detected using surface-confined redox and ion-pairing reactions

This article describes the use of a redox-induced ion-pairing reaction confined to an electrode surface to detect the micellar aggregation of ionic surfactants in water. Cyclic voltammetry characterizes the Faradaic response of self-assembled monolayers (SAMs) of ferrocenyldodecanethiolate on gold in aqueous solutions of the sodium salts of the anionic surfactants n-decyl sulfate, n-decyl sulfonate, and taurodeoxycholate, the bromide salt of the cationic surfactant decyltrimethylammonium, and the sodium salt of the azo dye Orange II. These electrolytes present different aggregation behaviors in water. The cyclic voltammograms indicate that the surfactant and dye anions and the bromide counteranion of the cationic decyltrimethylammonium pair with the electrogenerated SAM-bound ferrocenium. The voltammetric signatures are sensitive to the concentration and aggregation state of the ions in solution. The concentration dependence of the apparent redox potential (E degrees'(SAM)) presents the same features observed by potentiometry using surfactant ion-selective or bromide electrodes, indicating that E degrees'(SAM) tracks the activity of the unaggregated or free surfactant, dye or bromide anions in solution. The formation of micellar aggregates above the critical micelle concentration (cmc) causes the free anion activity to deviate from the molar concentration of added surfactant, resulting in a break in the plot of E degrees'(SAM) versus the logarithm of the surfactant concentration. The quantity of surfactant anions associated to the oxidized SAM increases with the solute concentration and plateaus out at concentrations > cmc. These findings point to the potential application of ferrocene-terminated SAMs to the investigation of ionic micelle-forming systems and the determination of their cmc’s. (C) 2019 Elsevier Ltd.

Effect of Wilforine on the Calcium Signaling Pathway in Mythimna separata Walker Myocytes Using the Calcium Imaging Technique

Although the action site of wilforine is located in the muscle tissue of insects, the insecticidal mechanism of wilforine is not yet clear. This research explored the effects of wilforine on the calcium signaling pathway using the calcium imaging technique to reveal the insecticidal mechanism. It was confirmed that wilforine had strong cytotoxicity to Mythimna separata myocytes with the IC50 values of 25.14 and 19.65 mg/L using CCK-8 and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide methods, respectively. The morphological development of M. separata myocytes was also affected. The calcium imaging technique showed that the intracellular calcium ion concentration ([Ca2+](i)) increased by 23.45% of the initial value after being treated with 100 nM wilforine. However, wilforine did not increase [Ca2+](i) after the myocytes were preincubated with thapsigargin, and the [Ca2+](i) could not be decreased by 50 mu M ryanodine after being treated with 100 nM wilforine. These results indicated that the targets of wilforine are located in the sarcoplasmic reticulum, and ryanodine receptor (RyR) is an important action target of wilforine. Furthermore, wilforine can also activate the inositol triphosphate receptor (IP3R), which was confirmed through the use of 2-aminoethyl diphenylborinate, an inhibitor of IP3R. Connected with previous research studies, it can be concluded that wilforine affects the calcium signaling pathway by combining with RyR and IP3R, causing calcium dyshomeostasis, which results in insect paralysis and death.
