Controlling the reactivity of [Pd-(II)(N boolean AND N boolean AND N)Cl] plus complexes using 2,6-bis (pyrazol-2-yl)pyridine ligands for biological application: Substitution reactivity, CT-DNA interactions and in vitro cytotoxicity study

Four [(NNN)(PdCl)-Cl-(II)]+ complexes [chloride-(2,2 ‘:6 ‘,2 ”-terpyridine)Pd-(II)]Cl (PdL1), [chlorido(2,6-bis(N-pyrazol-2-yl)pyridine)Pd(II)]Cl (PdL2), [chlorido(2,6-bis(3,5-dimethyl-N-pyrazol-2-yl)pyridine)Pd(II)]Cl (PdL3) and [chlorido(2,6-bis(3,5-dimethyl-N-pyrazol-2-ylmethyl)pyridine)Pd(II)]BF4 (PdL4) were synthesized and characterized. The rates of substitution of these Pd(II) complexes with thiourea nucleophiles viz; thiourea (Tu), N,N ‘-dimethylthiourea (Dmtu) and N,N,N ‘,N ‘-tetramethylthiourea (Tmtu) was investigated under pseudo first order conditions as a function of nucleophile concentration [Nu] and temperature using the stopped-flow technique. The observed rate constants vary linearly with [Nu]; k(obs) = k(2)[Nu] and decreased in the order: PdL1 > PdL2 > PdL3 >> PdL4. The lower pi-acceptability of the cis-coordinated N-pyrazol-2-yl groups (which coordinates via pyrazollic-N pi-donor atoms) of the PdL2-4 significantly decelerates the reactivity relative to PdL1. Furthermore, the six-membered chelates having methylene bridge in PdL4 do not allow pi-extension in the ligand and introduces steric hindrance further lowering the reactivity. Trends in DFT calculated data supported the observed reactivity trend. Spectrophotometric titration data of complexes with calf thymus DNA (CT-DNA) and viscosity measurements of the resultant mixtures suggested that associative interactions occur between the complexes and CT-DNA, likely through groove binding with high binding constants (K-b = 10(4) M-1). In vitro MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] cytotoxic activity data showed that PdL1 was the most potent complex against MCF7 breast cancer cells; its IC50 value is lower than that of cisplatin. The results demonstrate how modification of a spectator ligand can be used to slow down the reactivity of Pd(II) complexes. This is of special importance in controlling drug toxicity in both pharmaceutical and biomedical applications.

Discovery of novel indolyl-1,2,4-triazole hybrids as potent vascular endothelial growth factor receptor-2 (VEGFR-2) inhibitors with potential anti-renal cancer activity

Targeting VEGFR-2 signaling pathway is well-established as an important approach for the treatment of solid tumors, particularly renal cancer. Herein, novel indolyl-1,2,4-triazole hybrids were designed and synthesized as VEGFR-2 kinase inhibitors with potential anti-renal cancer activity. The structures of the newly synthesized compounds were confirmed based on their spectral and elemental analyses. The results of in vitro kinase assay indicated that all target compounds revealed submicromolar inhibition of VEGFR-2 kinase enzyme. Analogs 5c, 5d and 9b emerged as the most active compounds (IC50 = 0.034-0.064 mu M), showing VEGFR-2 inhibitory activity much superior to that of sunitinib reference drug (IC50 = 0.075 mu M). Moreover, compounds 5a, 8c, 9d, 12c were equipotent to sunitinib against VEGFR-2 kinase. Additionally, the most potent compounds were further examined for their anticancer activity against two human renal cancer cell lines. All screened compounds effectively inhibited the growth of the two tested cell lines with IC50 values spanning from sub-micromolar to low micromolar levels. Compounds 5b, 5d, 11c and 12c were three to five-fold more potent than sunitinib against CAKI-1 cell line. Analogue 8c was superior/comparable to sunitinib against CAKI-1/A498 cell lines. Moreover, compound 9d showed double potency of sunitinib against A498 cell line. Besides, compounds 8c and 12c demonstrated a safety profile much better than that of sunitinib against non-cancer human renal cells. As well, the docked models of title compounds revealed strong interactions with key residues within the active site of VEGFR-2 kinase.

Self-cleaning BiOBr/Ag photocatalytic membrane for membrane regeneration under visible light in membrane distillation

In this study, an innovative electrospun photocatalyst self-cleaning BiOBr/Ag membrane is introduced for the MD treatment of dyeing wastewater coupled with post-MD UV and visible light exposure for fouled membrane regeneration. The E-BiOBr/Ag membrane was fabricated by successfully coating an electrospun membrane with BiOBr/Ag catalyst particles using electrospray technology, with the goal to achieve higher hydrophobicity and the reproducible property. Along with the E-BiOBr/Ag membrane, two commercial polyvinylidene difluoride (PVDF) and polytetrafluoroethylene (PTFE) membranes were tested for comparison. The fouling processes on all three membranes were monitored in real-time using optical coherence tomography (OCT). The coating of BiOBr/Ag particles on the E-BiOBr/Ag membrane’s surface accelerated dye foulant degradation through the electronholes’ strong oxidization capacity when exposed to UV. Meanwhile, after Ag nanoparticles were coated on the BiOBr photocatalyst by UV deposition method, not only improved the efficiency of electron separation and transfer but also lessened the electron recombination phenomenon effectively. Correspondingly, compared to the two commercial membranes, the BiOBr/Ag photocatalyst membrane achieved significant improvements in the recovery efficiencies of the water contact angle (95.6%) and water flux (92.2%) under UV illumination, pointing to its potential for fouled membrane regeneration. In addition, the deposition of Ag on BiOBr as cocatalyst enhanced the visible light harvesting. Finally, the BiOBr/Ag photocatalyst membrane maintained good flux recovery and dye rejection (99.9%) over a 5-cycle MD test coupled with visible light exposure, suggesting the application of the novel self-cleaning photocatalyst membrane as a potential alternative for upscaling MD technology to the industrial level.

Study on the clinical mechanism of Tong-Xie-An-Chang Decoction in the treatment of diarrheal irritable bowel syndrome based on single-cell sequencing technology

Background: Diarrhea-predominant irritable bowel syndrome (IBS-D) is a kind of functional gastrointestinal disorder with obscure pathogenesis, and exploration about differential gene expression and cell heterogeneity of T lymphocytes in peripheral blood in IBS-D patients still remains unknown. Clinicians tend to use symptomatic treatment, but the efficacy is unstable and symptoms are prone to relapse. Traditional Chinese Medicine (TCM) is used frequently in IBS-D with stable and lower adverse effects. Tong-Xie-An-Chang Decoction (TXACD) has been proven to be effective in the treatment of IBS-D. However, the underlying therapeutic mechanism remains unclear. This trial aims to evaluate the clinical efficacy and safety of TXACD in IBS-D and elucidate the gene-level mechanism of IBS-D and therapeutic targets of TXACD based on single-cell sequencing technology. Methods/design: This is a randomized controlled, double-blind, double-simulation clinical trial in which 72 eligible participants with IBS-D and TCM syndrome of liver depression and spleen deficiency will be randomly allocated in the ratio of 1:1 to two groups: the experimental group and the control group. The experimental group receives Tong-Xie-An-Chang Decoction (TXACD) and Pinaverium bromide tablets placebo; the control group receives pinaverium bromide tablets and TXACD placebo. Each group will be treated for 4 weeks. The primary outcome: the rate of IBS-Symptom Severity Score (IBS-SSS). The secondary outcomes: TCM syndrome score, adequate relief and IBS-Quality of Life Questionnaire (IBS-QOL). Mechanistic outcome is the single-cell sequencing profiling of the T lymphocytes in peripheral blood from IBS-D participants before and after the treatment and healthy individuals. Discussion: This trial will prove the efficacy and safety of TXACD with high-quality evidence and provide a comprehensive perspective on the molecular mechanism of IBS-D by single-cell sequencing profiling, which makes us pinpoint specific biomarkers of IBS-D and therapeutic targets of TXACD.

Silibinin encapsulation in polymersome: A promising anticancer nanoparticle for inducing apoptosis and decreasing the expression level of miR-125b/miR-182 in human breast cancer cells

Silibinin, a polyphenolic flavonolignan, is well-known as a safe therapeutic drug without any side effects in the treatment of many malignancies especially cancerous cells. In this study, to overcome problems such as low solubility of silibinin and to enhance its delivery to cancerous cells, we encapsulated silibinin in polymersome nanoparticles. Physicochemical measurements such as dynamic light scattering, transmission electron microscopy, scanning electron microscopy, and atomic force microscopy confirmed the proper encapsulation of silibinin in nanoparticles. Furthermore, antiproliferative and apoptotic activities of silibinin encapsulated in polymersome nanoparticles (SPNs) on MDA-MB-231 breast cancer cell line were validated by3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, Annexin V/Propidium Iodide measurement, and cell cycle analysis. In addition, quantitative reverse transcription polymerase chain reaction analysis confirmed that SPNs can repress oncogenic microRNAs (miRNAs) such as miR-125b and miR-182, as well as antiapoptotic genes such as Bcl2. SPNs can also induce overexpression of proapoptotic target genes such as P53, CASP9, and BAX directly and/or indirectly (through regulation of miRNAs). Our results suggested that polymersomes can be used as stable carriers in nano-dimensions and SPNs can be considered as a promising pharmacological agent for cancer therapy.

Organic acids modify the binding selectivity of crosslinked poly(ionic liquid) between Sb(III) and Sb(V)

Antimony binding properties of a poly(ionic liquid), synthesised by crosslinking polymerisation of 1-butyl-3-vinyl-imidazolium bromide with N, N-methylene diacrylamide, in presence of complexing organic acids have been investigated. Sorption of Sb(V), Sb(III), and organic acids from their individual solutions and solutions containing antimony and organic acid by the crosslinked poly(ionic liquid) (P(BuVImBr-MDAA)) were studied at different pH conditions. The complexing organic acids, namely tartaric acid (TA), ascorbic acid (AA), citric acid (CA), EDTA and nitrilotriacetic acid (NTA), were shown to effect substantial changes in the antimony binding properties of P(BuVImBr-MDAA). Remarkable change in Sb(III) – Sb(V) selectivity of P(BuVImBr-MDAA) was observed in the presence of EDTA, NTA and CA. In the presence of EDTA, the selectivity could be toggled between Sb(III) and Sb(V) by varying the solution pH (initial). At pH 2.0 and 3.0, the uptake of Sb(V) was found to be higher than Sb(III) whereas at pH 4.0 there was about 40% reduction in Sb(III) uptake and no uptake of Sb (V). Citric acid and NTA, at pH 2.0 and pH 4.0 respectively, were found to be better choice for Sb(III) Sb(V) separation using P(BuVImBr-MDAA) as there was negligible reduction in Sb(III) uptake and nil uptake of Sb(V). The pH dependent acid speciation and the nature of complexes influenced the selectivity. Tartaric acid was shown to be the most suitable organic acid for effective removal of antimony (both Sb(III) and Sb(V)) without compromising on the binding capacity.

Dielectric properties of an organic ferroelectric of bromide diisopropylammonium embedded into the pores of nanosized Al2O3 films

The study presents experimental results for investigating linear and nonlinear dielectric properties of nanocomposites based on bromide diisopropylammonium (C6H16NBr, DIPAB) and aluminum oxide films (Al2O3) with pore diameter of 330, 100 and 60nm. It was indicated that the phase transition was blurred and shifted toward lower temperatures. This anomaly became more significant with decreasing pore size. The reduction of phase transition temperature in the nanocomposites, containing DIPAB, was consistent with theoretical models for the influence of size effects on the structural phase transition.

Innovative Turbine Intake Air Cooling Systems and Their Rational Designing

The efficiency of cooling ambient air at the inlet of gas turbines in temperate climatic conditions was analyzed and reserves for its enhancing through deep cooling were revealed. A method of logical analysis of the actual operation efficiency of turbine intake air cooling systems in real varying environment, supplemented by the simplest numerical simulation was used to synthesize new solutions. As a result, a novel trend in engine intake air cooling to 7 or 10 degrees C in temperate climatic conditions by two-stage cooling in chillers of combined type, providing an annual fuel saving of practically 50%, surpasses its value gained due to traditional air cooling to about 15 degrees C in absorption lithium-bromide chiller of a simple cycle, and is proposed. On analyzing the actual efficiency of turbine intake air cooling system, the current changes in thermal loads on the system in response to varying ambient air parameters were taken into account and annual fuel reduction was considered to be a primary criterion, as an example. The improved methodology of the engine intake air cooling system designing based on the annual effect due to cooling was developed. It involves determining the optimal value of cooling capacity, providing the minimum system sizes at maximum rate of annual effect increment, and its rational value, providing a close to maximum annual effect without system oversizing at the second maximum rate of annual effect increment within the range beyond the first maximum rate. The rational value of design cooling capacity provides practically the maximum annual fuel saving but with the sizes of cooling systems reduced by 15 to 20% due to the correspondingly reduced design cooling capacity of the systems as compared with their values defined by traditional designing focused to cover current peaked short-term thermal loads. The optimal value of cooling capacity providing the minimum sizes of cooling system is very reasonable for applying the energy saving technologies, for instance, based on the thermal storage with accumulating excessive (not consumed) cooling capacities at lowered current thermal loads to cover the peak loads. The application of developed methodology enables revealing the thermal potential for enhancing the efficiency of any combustion engine (gas turbines and engines, internal combustion engines, etc.).
