Protein kinases orchestrate diverse cellular functions; however, their dysregulation is linked to metabolic dysfunctions, associated with many diseases, including cancer. Mitogen-Activated Protein (MAP) kinase is a notoriously oncogenic signaling pathway in human malignancies, where the extracellular signal-regulated kinases (ERK1/2) are focal serine/threonine kinases in the MAP kinase module with numerous cytosolic and nuclear mitogenic effector proteins. Subsequently, hampering the ERK kinase activity by small molecule inhibitors is a robust strategy to control the malignancies with aberrant MAP kinase signaling cascades. Consequently, new heterocyclic compounds, containing a sulfonamide moiety, were rationally designed, aided by the molecular docking of the starting reactant 1-(4-((4-methylpiperidin-1-yl)sulfonyl)phenyl)ethan-1-one (3) at the ATP binding pocket of the ERK kinase domain, which was relying on the molecular extension tactic. The identities of the synthesized compounds (4-33) were proven by their spectral data and elemental analysis. The target compounds exhibited pronounced anti-proliferative activities against the MCF-7, HepG-2, and HCT-116 cancerous cell lines with potencies reaching a 2.96 mu M for the most active compound (22). Moreover, compounds 5, 9, 10b, 22, and 28 displayed a significant G2/M phase arrest and induction of the apoptosis, which was confirmed by the cell cycle analysis and the flow cytometry. Thus, the molecular extension of a small fragment bounded at the ERK kinase domain is a valid tactic for the rational synthesis of the ERK inhibitors to control various human malignancies.

Herein, Fe3O4 nano-particles are anchored over nitrogen doped reduced graphene oxide Fe3O4@N-rGO) structure to accommodate electric and magnetic components, so that it could match both the conduction and polarization loss to augment the attenuation of electromagnetic radiation. The formation of condensed heteroaromatic structure and decoration of Fe3O4 particles on r-GO structure are confirmed by photoelectron spectroscopy (XPS). high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD). The Fe3O4@N-rGO hybrid is subsequently dispersed in epoxy matrix, which result in significantly higher electrical conductivity (1.31 s/m) and electromagnetic interference (EMI) shielding efficiency (- 26 dB at 1 mm thickness). It was assumed that presence of electric-magnetic integrated Fe3O4@N-rGO hybrid in epoxy matrix significantly improved the interfacial polarization and anisotropy energy, which was reflected in absorption loss value of -27 dB. The composites also exhibited enhanced mechanical and thermo-mechanical properties coupled with improved thermal stability.

A colorimetric and visual assay is described for the herbicide aminotriazole (ATZ). It is based on the etching of gold nanorods (AuNRs) by iodine which is formed on oxidation of iodide via H2O2. Longitudinal etching of the AuNRs occurs quickly and is accompanied by a color change from dark blue to red. In the absence of ATZ and the presence of active catalase (CAT), H2O2 is quickly decomposed into water, and the AuNRs will not be etched. In thepresence of ATZ, CAT is partially deactivated, and this affects the amount of available H2O2 and, consequently, of the iodine. Hence, the color is significantly changed. The color changes can be easily detected with bare eyes. The assay has a linear response in the 5 to 70 mu M concentration range, with a detection limit of 1.3 mu M and high selectivity for ATZ. It was applied to the determination of ATZ in water and food samples.

Graphitic carbon nitride (g-C3N4) has been shown as a promising visible-light photosensitizer for photodynamic therapy (PDT) application. Nevertheless, its therapeutic efficiency is limited by the low efficiency of visible-light utilization. To overcome this issue, 3-amino-1,2,4-triazole-derived graphitic carbon nitride nanosheets (g-C3N5 NSs) are prepared for PDT application. The addition of nitrogen-rich triazole group into the g-C3N4 motif significantly makes the light absorption of g-C3N5 NSs red-shift with the band gap down to 1.95 eV, corresponding to a absorption edge at a wavelength of 636 nm. g-C3N5 NSs generate superoxide anion radicals (O-2(center dot-)) and singlet oxygen (O-1(2)) under the irradiation of a low-intensity white light emitting diode. Owing to the high efficiency of visible-light utilization, g-C3N5 NSs show about 9.5 fold photocatalytic activity of g-C3N4 NSs. In vitro anticancer studies based on the results of CCK-8 assay, Calcein-AM/PI cell-survival assay and photo-induced intracellular ROS level analysis in living HeLa cells demonstrate the potential of g-C3N5 NSs as a low-toxic and biocompatible high-efficient photosensitizer for PDT.

Developmentally-lead (Pb)-exposed rats showed an enhanced vulnerability to the stimulating and motivational effects of ethanol (EtOH). This is accompanied by differential activity of the brain EtOH-metabolizing enzymes catalase (CAT) and mitochondrial aldehyde dehydrogenase (ALDH2). Based on the theory that brain acetaldehyde accumulation is associated with the reinforcing properties of EtOH, this study sought to determine brain CAT and ALDH2 expression in limbic areas of control and Pb-exposed animals after voluntary EtOH intake. Thirty-five-day-old rats perinatally exposed to 220 ppm Pb were offered with water or increasing EtOH solutions (2-10% v/v) during 28 days until postnatal day (PND) 63. Once intake was stable, the animals were administered: 1) saline (SAL; test days 21-24 or 21-28, as corresponds), or 2) a CAT inhibitor: 3-amine 1, 2, 4-triazole (AT; 250 mg/kg intraperitoneally [i.p.], 5 h before the last eight EtOH intake sessions -test days 21-24 and 25-28), or 3) a CAT booster: 3-nitropropionic acid (3NPA; 20 mg/kg subcutaneously [s.c.], 45 min before the last four EtOH intake sessions -test days 25-28). Two additional groups were centrally-administered cyanamide (CY, an ALDH2 inhibitor, 0.3 mg i.c.v. immediately before the last four EtOH sessions, test days 25-28) or its corresponding vehicle (VEH). Lead exposure increased EtOH intake, an effect potentiated in both groups by 3NPA or CY pretreatments and reduced by AT, albeit selectivity in the Pb group. Catalase abundance in limbic areas parallels these observations in the Pb group, showing higher CAT expression in all areas after EtOH consumption respect to the controls, an effect prevented by AT administration. In contrast, ALDH2 expression was reduced in the Pb animals after EtOH intake, with CY potentiating this effect in all brain areas under study. Based on these results and on previous evidences, we suggest that Pb exposure promotes acetaldehyde accumulation in limbic regions, providing some insights into the mechanism of action that underlies the vulnerability to the excessive EtOH consumption reported in these animals.

The Mbp1 protein functions as a DNA-binding protein in the MluI cell cycle box-binding complex and plays significant roles in yeast development. In this study, an ortholog of yeast Mbp1, BbMbp1, was characterized in a filamentous insect mycopathogen, Beauveria bassiana. BbMbp1 plays an important role in morphological changes under aerial and liquid environments. On the aerial surface, BbMbp1 was indispensable for the biogenesis of conidiophores and conidiation. Under submerged conditions, the increment BbMbp1 mutant displayed abnormal spore-producing structures, with a dramatic decrease in blastospore yield (similar to 95%). The virulence of the increment BbMbp1 mutant was notably weakened, which might be due to the defect in in vivo blastospore formation in the insect. Moreover, disruption of BbMbp1 resulted in a substantial reduction in hyphal growth on cadavers. Comparative transcriptomics revealed that BbMbp1 mediated different transcriptomes during the formation processes of conidia and blastospores. Yeast one-hybrid assays demonstrated that BbMbp1 was required for transcriptional control of a cell wall protein gene, BbCwp, and an integral membrane protein gene, BbImp that played significant roles in conidiation and blastospore formation respectively. Our results demonstrate that BbMbp1 contributes to the morphological transitions in the pathogenic and saprophytic growth of B. bassiana via different genetic pathways.

Despite the richness of data collected on pesticide concentrations in ambient air in France, knowledge on this topic remains partial and heterogeneous in the absence of specific regulations. The population exposure remains thus difficult to estimate; therefore it was necessary to define modalities for implementing national monitoring of pesticides in ambient air in metropolitan France and in the overseas territories. The objective of this work was to identify which active substances (a.s.) have to be monitored in priority. As part of a collective expertise, a group of multidisciplinary experts has developed a method to rank active substances authorised as plant protection products, biocides and antiparasitic agents, which were available on the French market in 2015. A 3-steps approach has been developed. The first step consisted of a theoretical approach based on a hierarchy of substances according to four criteria: (a) national uses, (b) emission potential to the air, (c) persistence in the air, and (d) chronic toxicity. The three first criteria give information on their potential to be present in the atmosphere, and the fourth criterion allows to consider their potential of hazard. The second step was an observational approach based on existing database on pesticide air measurements in France. In the third step, both approaches were combined using decision trees to select priority pesticides. Among the 1316 a.s. first identified from the EU Pesticides database, 90 were selected, among which 43 required metrological and/or analytical development. The experts recommended confirming the relevance of performing a longer term monitoring of these a.s. after a one-year exploratory campaign. The proposed method is reproduceable, transparent, easy to update (e.g. in the light of a change in product authorization), and can be adapted to other agricultural and geographical conditions, and objectives (e.g. monitoring of the ecotoxicological effects of pesticides).

8-Acetyl-7-hydroxy-4-methyl coumarin and 3-amion-1,2,4-triazole were used to prepare a Schiff base (Sbat). The [Ag(Sbat)(NO3)]center dot H2O and [Cu(Sbat)(OH)(H2O)(2)]center dot 3H(2)O complexes were separated by the reaction of the Schiff base with Ag(i) and Cu(ii) metal ions. All the prepared compounds were subjected to elemental and spectral analyses (IR, UV-vis, H-1 NMR, and mass spectroscopy). Moreover, the complexes were also subjected to TG analysis, molar conductance measurements, magnetic moment analysis, and XRD measurements. The value of the molar conductance designates their non-electrolytic character. The local minimum structure, global properties and nonlinear optical parameters of the Schiff base were calculated at the B3LYP/6-31++(d,p) level of theory and those of its complexes were calculated at the B3LYP/GENECP level. The electronic spectra in the UV-visible region of the Schiff base (Sbat) and [Ag(Sbat)(NO3)]center dot H2O and [Cu(Sbat)(OH)(H2O)(2)]center dot 3H(2)O complexes in DMSO as a solvent were investigated experimentally and theoretically using the time dependent density functional theory (TD-DFT) method at the CAM-B3LYP/6-311++G(d,p) level of theory. The studied compounds were screened for their in vitro antibacterial activity against three Gram-positive (B. subtilis, S. aureus and S. faecalis) and three Gram-negative bacteria (E. coli, N. gonorrhoeae and P. auregenosa). An antifungal assay was performed against two fungal (C. albicans and A. flavus) species. The Ag-Sbat complex showed the highest antimicrobial activity. The cytotoxic activity of the Schiff base and its silver complex was tested in vitro against the MCF-7 (breast cancer) and HCT-116 (colon cancer) cell lines.

Cancer is a leading cause of human death worldwide. One of the greatest challenges in cancer therapy is the discovery and design of novel products with potential anti-tumor activities. In this study, a new protocol involves three-component condensation of the 3-amino-1,2,4-triazole as a 1,3-binucleophile, versatile aldehydes and Nmethyl-1-(methylthio)-2-nitroethenamine as an enamine analogous in the presence of trichloroacetic acid as a Bronsted-Lowry acidic promoter leads to new functionalized N-alkyl-6-nitro-3,5-dihydro-[1,2,4]triazolo [1,5-a] pyrimidin-7-amine in moderate to good yields. The presence of five nitrogen heteroatoms in the product structure has gathered immense attention among chemists and biologists due to their biological values. Therefore, we evaluated the anti-tumor activity of our synthetic compounds on different cancer cells including human malignant melanoma cells (A375), prostate cancer cells (PC3 cells, LNCaP cells) and normal cells HDF (human dermal fibroblast). Notably, we found that compound 4b that contains a nitro group has the best antitumor activity on three different cancer cells. By using DAPI staining, we showed cancer cells death. Apoptosis induction was shown using quantitative real time PCR (qRT-PCR) by evaluating of Bax and Bcl2 mRNA levels. Finally, we demonstrated that 4b has epithelial-to-mesenchymal transition (EMT) inhibition effect on cancer cells (by induction of E-cadherin and reduction of vimentin mRNA expression levels as two potential EMT markers). So, 4b could be an anti-cancer promising drug. Although, in vivo experiments will be required to evaluate possible side effects.
