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.

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.

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.

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.

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.

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.

Aminotriazole (AT), an organic heterocyclic compound, is an unselective herbicide used to deal with a large assortment of weeds by preventing the biosynthesis of carotenoids. It is a malignant agent to human beings as well as to animals. This study is focused on the nanomolar detection of AT with multiwalled carbon nanotubes along with calcium-doped zinc oxide nanoparticles adapted for a nano-composite dependent glassy carbon electrode (MWCNTs/Ca-ZnO/GCE). The developed MWCNTs/Ca-ZnO/GCE showed an excellent electrocatalytic response to AT in 3.0 pH of 0.2 M phosphate buffer solution (PBS). There was an increase in the peak current of AT, i.e., 7.726 mu A, with MWCNTs/Ca-ZnO/GCE when it was compared with the peak current of AT at the bare glassy carbon electrode (GCE), 3.478 mu A, due to the semiconducting properties of the doped nanoparticles. Various techniques were employed to study the different parameters such as scan rate, pH variations, and concentration variations by cyclic voltammetry (CV), square wave voltammetry (SWV), and linear sweep voltammetry (LSV) in order to probe the mechanism, number of participating electrons, type of process, detection limit, and quantification limit. The Ca-ZnO nanoparticles (NPs) were synthesized at the proportion of 5.0% and these were characterized by energy dispersive X-ray analysis (EDX), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). The developed sensor was applied for real sample analysis like soil and water by quantifying the AT in the samples and the output was found to be precise with good recovery results.

Cerrena unicolor is a wood-degrading basidiomycete with ecological and biotechnological importance. Comprehensive Biolog-based analysis was performed to assess the metabolic capabilities and sensitivity to chemicals of C. unicolor FCL139 growing in various sawdust substrates and light conditions. The metabolic preferences of the fungus towards utilization of specific substrates were shown to be correlated with the sawdust medium applied for fungus growth and the light conditions. The highest catabolic activity of C. unicolor was observed after fungus precultivation on birch and ash sawdust media. The fungus growing in the dark showed the highest metabolic activity which was indicated by capacity to utilize a broad spectrum of compounds and the decomposition of 74/95 of the carbon sources. In all the culture light conditions, p-hydroxyphenylacetic acid was the most readily metabolized compound. The greatest tolerance to chemicals was also observed during C. unicolor growth in darkness. The fungus was the most sensitive to nitrogen compounds and antibiotics, but more resistant to chelators. Comparative analysis of C. unicolor and selected wood-decay fungi from different taxonomic and ecological groups revealed average catabolic activity of the fungus. However, C. unicolor showed outstanding capabilities to catabolize salicin and arbutin. The obtained picture of C. unicolor metabolism showed that the fungus abilities to decompose woody plant material are influenced by various environmental factors.

The study is aimed at the induction of systemic disease resistance by a local oxidative burst caused by inhibition of plant antioxidant enzymes. A possible involvement of ROS was ascertained. Inhibitors of superoxide dismutase and catalase, respectively, diethyldithiocarbamate (DDC) and aminotriazole (AT) were applied to the fist (local) true leaf of cucumber seedlings (Cucumis sativus L.). When the second and third (systemic) leaves developed, they were inoculated with spores of the virulent fungus Cladosporium cucumerinum Ell. et Arth. causing cucurbit scab. The inhibitors at concentrations nontoxic to leaves or spores greatly reduced the disease symptoms on the systemic leaves. The inhibition of both enzymes was confirmed, and increased superoxide production was found in the chemically treated local leaf. In case of a treatment with water, diffusates of the healthy systemic leaves stimulated spore germination, and those of infected systemic leaves were ineffective. Treatment of the local leaf with any compound systemically suppressed the aforementioned stimulation in the healthy counterpart and provided fungitoxicity in the infected one. Both antifungal effects were abolished by diffusate boiling, suggesting protein involvement. Meanwhile, the effects were insensitive to antioxidants and, apparently, independent of reactive oxygen. DDC and AT did not promote salicylic acid accumulation in infected systemic leaves; presumably, the disease control did not represent systemic acquired resistance. It is suggested that both inhibitors induce some kind of systemic resistance through the local oxidative burst caused by inhibition of antioxidant enzymes. The systemic implementation of the resistance may include antifungal effects.
