Ten 5-functionalized derivatives of 1,3-oxazole-4-carboxylate and 1,3-oxazole-4-carbonitrile were synthesized and their antiviral activities against the human cytomegalovirus (HCMV) were evaluated in vitro. Bioassays showed that seven compounds exhibited considerably higher antiviral activity (EC50:<0.05M) against a normal laboratory HCMV strain (AD-169) in human foreskin fibroblast cells than Ganciclovir (EC50=0.32M), an anti-HCMV agent in clinical use. Additionally, the HCMV-resistant isolate (GDGr K-17) was tested for sensitivity to 1,3-oxazole derivatives with most antiviral potency against the strain AD169. A one of them (5-((2-hydroxyethyl)(methyl)amino)-2-(4-methylphenyl)-1,3-oxazole-4-carbonitrile) showed very high potency (EC50:<0.05; CC50: >150 mu M, and SI50=3125) towards the resistant isolate compared to standard drugs Cidofovir (EC50=0.10 mu M, CC50: >30 mu M and SI50: <4). But, in contrast to the primary assays, the antiviral activity of these compounds against both the normal strain and the resistant isolate of HCMV were considerably less than one of Cidofovir in secondary assay. These results provided evidence that derivatives of 1,3-oxazole could be useful for developing new anti-HCMV drugs.

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.

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.

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).

Deleterious mutations in Breast Cancer 1 (BRCA1) are associated with an increased risk of breast and ovarian cancer. Mutations in the tandem BRCA1 C-terminal (tBRCT) protein domain disrupt critical protein interactions required for the faithful repair of DNA through homologous recombination, which contributes to oncogenesis. Our studies have identified RICTOR, PRR5, and SIN1 subunits of the mammalian target of rapamycin complex 2 (mTORC2) as interacting partners with the tBRCT domain of BRCA1 leading to the disruption of the mTORC2 complex. However, the interplay between mTORC2 signaling and BRCA1 function in the DNA damage response (DDR) remains to be determined. In this study, we used protein interaction assays to determine the binary interactions between the tBRCT domain and mTORC2 subunits, evaluated the impact of mTOR inhibition on the transcriptional function of the tBRCT, evaluated the impact of mTOR signaling on BRCA1 recruitment to DNA damage-induced foci and determined the breast cancer cell line response to mTOR inhibition dependent upon BRCA1 expression and mutation. This study determined that PRR5, RICTOR, and SIN1 could each independently interact with the BRCA1 tBRCT. Inhibition of mTORC1, but not mTORC1/2, increases BRCA1 transcriptional activation activity. Treatment with pan-mTOR inhibitor PP242 diminishes DNA damage-induced gamma H2AX and BRCA1 foci formation. Breast cancer cells lacking expression of functional BRCA1 are more sensitive to mTOR inhibitors. These data suggest that mTOR signaling is required for BRCA1 response to DNA damage and breast cancer cells lacking BRCA1 are more sensitive to pan-mTOR inhibition. This work suggests chemotherapeutic strategies using mTOR inhibitors could be tailored for patients that lack functional BRCA1.

This article is focused on the preparation and characterization of functional nanosilica incorporated dental resins with better mechanical, cytotoxicity, sorption, and solubility properties. Silica nanoparticles were synthesized via Stober method and were functionalized with 3-amino-1,2,4-triazole. Dental nanocomposites were produced by embedding the functionalized nanosilica into bisphenol-A-glycidyl methacrylate/triethylene glycol dimethacrylate matrix to form B1-B6 series. This was achieved by mechanical mixing of the monomer (50:50 wt%), filler (10-60 wt%), initiator combination (CQ/EDMAB:O. 1 :0.4 wt%) and then followed by LED light curing (wavelength: 450-500 nm, power density:1000 mW cm(-2)) for 60 s. Fourier transform infrared spectroscopy, scanning electron microscopy, and thermogravimetric analysis techniques were used for characterization of the materials. Cytotoxicity tests were performed to evaluate cell viability and mechanical tests were done to check mechanical strength and stability of the materials. The mean sorption and solubility values of the materials were measured by making a series of experiments on different composite formulations.

Interaction of methyl 3-ethoxy-2-(2,5-dichloro-3-thenoyl)acrylate (I) with 3-aminopyrazole and 3- amino-1,2,4-triazole generated the respective pyrazolo [1,5-alpha]pyrimidine (4) and triazolo[1,5-alpha]pyrimidine (7). The formation of 4 entails selective and consecutive displacement of the 3-ethoxy and methoxy (ester) anions in I by 3-NH2 and 1-NH of 3-aminopyrazole. On the other hand, the formation of 7 implies selective displacement of 3-ethoxy in I by the ring-NH followed by cyclocondensation involving the keto group in I and 3-NH2 of aminotriazole. This latter selective displacement sequence is also followed by 3-amino-5-hydroxypyrazole in its reaction with I. The structures of the new compounds are supported by microanalytical and spectral data.

An effectively Zn/Zn stabilizer system instead of traditional Ca/Zn stabilizer system was put forward, which contained a new triazole-based zinc-containing complex (abbreviated as [Zn(ttr)(St)]) and Zinc stearate (ZnSt(2)). Without Ca soap in the system, [Zn(ttr)(St)] itself could effectively absorb HCl and provided PVC with higher transparency and better thermal stability without zinc burning than commercial CaSt(2)/ZnSt(2) stabilizer system, verified by Congo red tests and discoloration tests and dynamic thermal stability analysis. In addition, [Zn(ttr)(St)] could further delay zinc burning of other zinc soaps, constituting Zn/Zn stabilizer system. This is attributed to the strong ability of restricting ZnCl2 of 3-amino-1,2,4-triazole released from [Zn(ttr)(St)] after absorbing HCl. After adding ESBO, PVC stabilized by [Zn(ttr)(St)]/ZnSt(2)/ESBO showed excellent transparency and thermal stability. We believe that [Zn(ttr)(St)] can act as a novel double agent with the stabilization effects of zinc soap and calcium soap at the same time and this Zn/Zn stabilizer system may inaugurate a new stabilizer system for PVC with synergistic effect.

Odors carrying intrinsic values often trigger instinctive aversive or attractive responses. It is not known how innate valence is encoded. An intuitive model suggests that the information is conveyed through specific channels in hardwired circuits along the olfactory pathway, insulated from influences of other odors, to trigger innate responses. Here, we show that in mice, mixing innately aversive or attractive odors with a neutral odor and, surprisingly, mixing two odors with the same valence, abolish the innate behavioral responses. Recordings from the olfactory bulb indicate that odors are not masked at the level of peripheral activation and glomeruli independently encode components in the mixture. In contrast, crosstalk among the mitral and tufted (M/T) cells changes their patterns of activity such that those elicited by the mixtures can no longer be linearly decoded as separate components. The changes in behavioral and M/T cell responses are associated with reduced activation of brain areas linked to odor preferences. Thus, crosstalk among odor channels at the earliest processing stage in the olfactory pathway leads to re-coding of odor identity to abolish valence associated with the odors. These results are inconsistent with insulated labeled lines and support a model of a common mechanism of odor recognition for both innate and learned valence associations.
