An extensive research on aldose reductase inhibitory effects of new 4H-1,2,4-triazole derivatives

Aldose reductase (AR) is a key enzyme, which triggers the excessive accumulation of sorbitol in insulin independent tissues leading to severe diabetes-induced microvascular complications. Substantial evidence has proven that AR inhibition is a well-established strategy to attenuate these complications. In the current work, new 2-[(4-amino-5-aryl-4H-1,2,4-triazol-3-yl)thio]-N-(thiazol/benzothiazol-2-yl)acetamides (1-18) were synthesized and evaluated for their inhibitory capacities on AR. 2-[(4-Amino-5-(4-methylphenyl)-4H-1,2,4-triazol-3-yl)thio]-N-(5-nitrothiazol-2-yl)acetamide (12) and 2-[(4-amino-5-(3-pyridyl)-4H-1,2,4-triazol-3-yl)thio]-N-(6-nitrobenzothiazol-2-yl)acetamide (17) were identified as the most effective AR inhibitors in this series with the K-i values of 0.04 +/- 0.01 mu M and 0.08 +/- 0.02 mu M, respectively as compared to quercetin (K-i = 5.66 +/- 0.66 mu M). These two compounds displayed competitive AR inhibition. MTT assay, a tetrazolium-based cell viability assay, was performed to determine the cytotoxic effects of compounds 1-18 on L929 mouse fibroblast (healthy) cell line. Compounds 1-18, except for compounds 10, 13, 14, 15 and 16, were found nontoxic against healthy cells. Besides, molecular docking studies were fundamentally in agreement with the biological data with regard to essential pi-pi interactions with Trp219, Phe122 and Trp111 residues in the active site of AR. Eventually, in vitro and in silico assays ascertain that in particular compounds 12 and 17 will attract a great notice as drug-like AR inhibitors for further investigations related to amelioration of long-term diabetic complications.

Birds feeding on tebuconazole treated seeds have reduced breeding output

Drilled seeds are an important food resource for many farmland birds but may pose a serious risk when treated with pesticides. Most compounds currently used as seed treatment in the EU have low acute toxicity but may still affect birds in a sub-chronic or chronic way, especially considering that the sowing season lasts several weeks or months, resulting in a long exposure period for birds. Tebuconazole is a triazole fungicide widely used in agriculture but its toxicity to birds remains largely unknown. Our aim was to test if a realistic scenario of exposure to tebuconazole treated seeds affected the survival and subsequent reproduction of the red-legged partridge (Alectoris rufa). We fed captive partridges with wheat seeds treated with 0%, 20% or 100% of tebuconazole application rate during 25 days in late winter (i.e. tebuconazole dietary doses were approximately 0.2 and 1.1 mg/kg bw/day). We studied treatment effects on the physiology (i.e. body weight, biochemistry, immunology, oxidative stress, coloration) and reproduction of partridges. Exposed birds did not reduce food consumption but presented reduced plasmatic concentrations of lipids (triglycerides at both exposure doses, cholesterol at high dose) and proteins (high dose). The coloration of the eye ring was also reduced in the low dose group. Exposure ended 60 days before the first egg was laid, but still affected reproductive output: hatching rate was reduced by 23% and brood size was 1.5 times smaller in the high dose group compared with controls. No significant reproductive effects were found in the low dose group. Our results point to the need to study the potential endocrine disruption mechanism of this fungicide with lagged effects on reproduction. Risk assessments for tebuconazole use as seed treatment should be revised in light of these reported effects on bird reproduction. (C) 2020 Elsevier Ltd. All rights reserved.

New quinoline / chalcone hybrids containing 1,2,4-triazole moiety have been designed, synthesized and their structures elucidated and confirmed by various spectroscopic techniques. The designed compounds showed moderate to good activity on different NCI 60 cell lines in a single-dose assay with a growth inhibition rate ranging from 50% to 94%. Compounds 7b, 7d, 9b, and 9d were the most active compounds in most cancer cell lines with a growth inhibition percent between 77% and 94%. Newly synthesized hybrids were evaluated for their anti-proliferative activity against a panel of four human cancer cell lines. Compounds 7a, 7b, 9a, 9b, and 9d showed promising antiproliferative activities. These compounds were further tested for their inhibitory potency against EGFR and BRAF(V600E )kinases with erlotinib as a reference drug. The molecular docking study of compounds 7a, 7b, 9a, 9b, and 9d revealed nice fitting into the active site of EGFR and BRAF(V600E) kinases. Compounds 7b, 9b, and 9d displayed the highest binding affinities and similar binding pattern to those of erlotinib.

Single dose pharmacokinetics of topical iodiconazole creams in healthy Chinese volunteers

1.In this study, the pharmacokinetics of new triazole antifungal iodiconzole creams at target sites after single-dose topical application was investigated. 2.30 healthy Chinese volunteers were randomly divided into three groups after being stratified by sex, each group was given a single topical dose of 1%, 2%, 4% iodiconazole cream (0.4 g). Stratum corneum (SC) samples of treated sites were collected by tape-stripping method after the chosen contact times, and were extracted and analysed by a validated LC-MS method. 3.After single-dose topical application of 1%, 2%, 4% iodiconazole creams, the C-max of iodiconazole in SC was 1.2 +/- 0.7, 2.2 +/- 1.0, 2.4 +/- 1.0 mg/g; T-max was 3.3 +/- 1.1, 2.9 +/- 1.1, 3.8 +/- 0.4 h; t(1/2) was 6.6 +/- 3.4 h, 7.2 +/- 4.1 h, 5.9 +/- 2.9 h; AUC(0-t) was 10.9 +/- 3.0, 20.8 +/- 10.4, 20.9 +/- 7.9 mg center dot h/g; AUC(0-infinity) was 11.6 +/- 2.9, 23.5 +/- 14.4, 22.2 +/- 8.9 mg center dot h/g, respectively. The results showed that C-max, AUC(0-t) and AUC(0-infinity) did not increase proportionately with dose, which could also be due to the drug being saturated in the formulation at similar to 2%. 4.The results of this study could provide reference for the clinical medication and further study of the formulations.

Synthesis of [F-18]PS13 and Evaluation as a PET Radioligand for Cyclooxygenase-1 in Monkey

Cyclooxygenase-1 (COX-1) and its isozyme COX-2 are key enzymes in the syntheses of prostanoids. Imaging of COX-1 and COX-2 selective radioligands with positron emission tomography (PET) may clarify how these enzymes are involved in inflammatory conditions and assist in the discovery of improved anti-inflammatory drugs. We have previously labeled the selective high-affinity COX-1 ligand, 1,5-bis(4-methoxyphenyl)-3-(2,2,2-trifluoroethoxy)-1H-1,2,4-triazole (PS13), with carbon-11 (t(1/2) = 20.4 min). This radioligand ([C-11]PS13) has been successful for PET imaging of COX-1 in monkey and human brain and in periphery. [C-11]PS13 is being used in clinical investigations. Alternative labeling of PS13 with fluorine-18 (t(1/2) = 109.8 min) is desirable to provide a longer-lived radioligand in high activity that might be readily distributed among imaging centers. However, labeling of PS13 in its 1,1,1-trifluoroethoxy group is a radiochemical challenge. Here we assess two labeling approaches based on nucleophilic addition of cyclotron-produced [F-18]fluoride ion to gemdifluorovinyl precursors, either to label PS13 in one step or to produce [F-18]2,2,2-trifluoroethyl p-toluenesulfonate for labeling a hydroxyl precursor. From the latter two-step approach, we obtained [F-18]PS13 ready for intravenous injection in a decay-corrected radiochemical yield of 7.9% and with a molar activity of up to 7.9 GBq/mu mol. PET imaging of monkey brain with [F-18]PS13 shows that this radioligand can specifically image and quantify COX-1 without radiodefluorination but with some radioactivity uptake in skull, ascribed to red bone marrow. The development of a new procedure for labeling PS13 with fluorine-18 at a higher molar activity is, however, desirable to suppress occupancy of COX-1 by carrier at baseline.

Peptide Nucleic Acid with Double Face: Homothymine-Homocytosine Bimodal C alpha-PNA (bm-C alpha-PNA) Forms a Double Duplex of the bm-PNA(2):DNA Triplex

C alpha-bimodal peptide nucleic acids (bm-C alpha-PNA) are PNAs with two faces and are designed homologues of PNAs in which each aminoethylglycine (aeg) repeating unit in the standard PNA backbone hosts a second nucleobase at C alpha through a spacer chain with a triazole linker. Such bm-C alpha-PNA with mixed sequences can form double duplexes by simultaneous binding to two complementary DNAs, one to the base sequence on t-amide side and the other to the bases on the C alpha side chain. The synthesis of bm-C alpha-PNA with homothymine (T-7) on the t-amide face and homocytosine (C-5) on the C alpha side chain through the triazole linker was achieved by solid phase synthesis with the global click reaction. In the presence of complementary DNAs dA(8) and dG(6) at neutral pH, bm-C alpha-PNA 1 forms a higher order pentameric double duplex of a triplex composed of two bmC alpha-PNA-C-5:dG(5) duplexes built on a core (bm-Ca-PNA-T-7)(2):dA(8) triplex. Circular dichroism studies showed that assembly can be achieved by either triplex first and duplex later or vice versa. Isothermal titration calorimetry data indicated that the assembly is driven by favorable enthalpy. These results validate concurrent multiple complex formation by bimodal PNAs with additional nucleobases at C alpha or C gamma on the aeg-PNA backbone and open up ways to design programmed supramolecular assemblies.

Synthesis, structure and fluorescent sensing for nitrobenzene of a Zn-based MOF

Nitrobenzene (NB) can cause serious harm to ecosystems and human health. In order to identify and detect NB effectively, a micro-porous Zn-based metal-organic framework (Zn-MOF) material was prepared. Zn-MOF material named [Zn(L)] n was successfully synthesized by solvothermal method, using 1,3,5-tris (3-carboxy-triazole-methylene)-2,4,6-tritoluene (H3L) as organic ligand. Its stucture was characterized by X-ray single-crystal diffraction, elemental analysis, IR spectra and thermogravimetric (TG) analysis. X-ray single-crystal diffraction analysis exhibits that Zn-MOF belongs to the orthorhombic crystal system, space group Pbcn. The central Zn(II) ion exhibits a octahedron {ZnN3O3} coordination geometry. Topological analysis shows that Zn-MOF exhibits a utp uninodal 3-connected 3D 2-interpenetrating framework with the point symbol (10(3)). Furthermore, the fluorescence quenching experimental results show that Zn-MOF is a potential fluorescent material that can selectively and sensitively fluorescent sensing NB. (C) 2020 Elsevier B.V.

Preparation of crosslinker-free anion exchange membranes with excellent physicochemical and electrochemical properties based on crosslinked PPO-SEBS

The process of crosslinking is widely employed to increase the physicochemical stability of anion exchange membranes and, in some cases, improve ion conductivity. For a general case in which a polymer is crosslinked by a crosslinking agent, the physicochemical properties of the polymer can be greatly altered, depending on the type of crosslinking agent. In this study, we induced crosslinking without a crosslinking agent to intentionally maximise various physical properties (i.e., mechanical properties, swelling ratios, and so forth) of two commercially-available polymers. A triazole was incorporated into the conducting group to maximise the ion conductivity, especially under room humidity (RH) conditions. The crosslinked PPO-SEBS membranes prepared through this approach were not only capable of forming very thin membranes (10 mu m thickness) with excellent physical properties (34.3 MPa of tensile strength and 91.6% of elongation at break) but also exhibited high hydroxide ion conductivity under 95% RH, and conductivity plays an important role in achieving good fuel cell performance. When the membrane electrode assembly (MEA), as fabricated utilising a crosslinked PPO-SEBS membrane and a platinum on carbon (Pt/C) catalyst on each electrode, was operated in conditions with a H-2/O-2 gas flow and a 60 degrees C temperature, a stable fuel cell performance was obtained for a long period of time (300 hours) at a maximum power density of 405 mW cm(-2). This result surpasses the performance of commercialized AEMs and is comparable with the performance levels of cutting-edge AEMs when operated under similar conditions.
