The isoindolinone and biaryl scaffolds are prevalent in natural products and drug molecules, which have showed broad and interesting biological activities. The efficient construction of such hybridized molecules and biological evaluation are of great interest to medicinal chemistry community. In this communication, we report an efficient Bronsted acid-promoted C(sp(3))-H functionalization approach that enables the rapid construction of biologically important isoindolinone/[1,2,4]triazolo[1,5-a]pyrimidine hybrids from 5-methyl-7-(2,4,6-trimethoxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidine, 2-formylbenzoic acid and various anilines. The title compounds were generated in high to excellent yields (up to 96%) regardless of the electronic nature and steric effects of the substituents. In this reaction, an isoindolinone scaffold, one C-C single bond, and two C-N bonds were formed simultaneously with high atom economy. In this work, we have envisioned that the methyl group linked to the electron-deficient N-heterocycles could be used as a new synthetic handle for late-state diversification and may have broad applications in the field of organic and medicinal chemistry. Besides, the title compounds have exhibited promising activity against the SKP2-CKS1 interaction.

Mechanisms controlling the expression of the electrically conductive pili (e-pili) of Geobacter species are of interest because of the important role of e-pili in diverse biogeochemical processes, anaerobic digestion and electromicrobiological applications. We investigated the function of the protein, designated Spc (short pilin chaperone), encoded by the gene immediately downstream from the gene for PilA, the monomer that assembles into e-pili. Multiple lines of evidence suggest that Spc forms an oligomer that is associated with the inner membrane. Mutating the start codon of spc to prevent translation increased the transcript abundance of pilA but greatly diminished the abundance of PilA, and e-pili could no longer be detected. Cross-linking, protein capture and two-hybrid studies demonstrated that Spc and PilA interacted. Two sites in PilA for electrostatic interaction with Spc were identified. The results demonstrate that Spc is required for PilA stability prior to incorporation into e-pili, suggesting that Spc has a chaperone function that may be specific to the relatively short PilA monomers that assemble into e-pili. These results are important for identifying microorganisms likely to express e-pili from (meta)genomic data and for the construction of microbial strains expressing e-pili.

A double-network anion exchange membrane (TA/AT-PEK/PVA-x) was prepared by Br-PEK and PVA, 3-amino-1,2,4 triazole forms a cross-linking structure with PVA under the action of 1,4-phthalaldehyde and then triazole can be linked with Br-PEK. The structure of membranes was verified by FT-IR. The composite membrane is uniform and smooth can be seen from the scanning electron microscope (SEM) and exhibit good hydrophilic/hydrophobic micro-phase separation structure proved by Transmission electron micrograph (TEM). The ionic conductivity of TA/AT-PEK/PVA-0.15 is 0.062 S/cm at 80 degrees C. With the addition of PVA within a certain range, the water uptake, swelling ratio hydroxide conductivity and alkaline stability are increase. The membranes are more flexible. After immersing in 4M NaOH solutions for 240 h at 80 degrees C, it remains at least 65% of its initial hydroxide ion conductivity of TA/AT-PEK/PVA-0.3 membrane. With the increasing number of water molecules solvating the hydroxide, its nucleophilicity and basicity were hindered, which enhance alkaline stability of anion exchange membranes.

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.

Intracerebroventricular (icv) injection of hydrogen peroxide (H2O2) or the increase of endogenous H2O2 centrally produced by catalase inhibition with 3-amino-1,2,4-triazole (ATZ) injected icv reduces the pressor responses to central angiotensin II (ANG II) in normotensive rats. In the present study, we investigated the changes in the arterial pressure and in the pressor responses to ANG II icv in spontaneously hypertensive rats (SHRs) and 2-kidney, 1-clip (2K1C) hypertensive rats treated with H2O2 injected icv or ATZ injected icv or intravenously (iv). Adult male SHRs or Holtzman rats (n = 5-10/group) with stainless steel cannulas implanted in the lateral ventricle were used. In freely moving rats, H2O2 (5 mu mol/1 mu l) or ATZ (5 nmol/1 mu l) icv reduced the pressor responses to ANG II (50 ng/1 mu l) icv in SHRs (11 +/- 3 and 17 +/- 4 mmHg, respectively, vs. 35 +/- 6 mmHg) and 2K1C hypertensive rats (3 +/- 1 and 16 +/- 3 mmHg, respectively, vs. 26 +/- 2 mmHg). ATZ (3.6 mmol/kg of body weight) iv alone or combined with H2O2 icv also reduced icv ANG II-induced pressor response in SHRs and 2K1C hypertensive rats. Baseline arterial pressure was also reduced (-10 to -15 mmHg) in 2K1C hypertensive rats treated with H2O2 icv and ATZ iv alone or combined and in SHRs treated with H2O2 icv alone or combined with ATZ iv. The results suggest that exogenous or endogenous H2O2 acting centrally produces anti-hypertensive effects impairing central pressor mechanisms activated by ANG II in SHRs or 2K1C hypertensive rats.

As the use of the new insensitive munitions compound 3-nitro-1,2,4-triazol-5-one (NTO) increases, wastewaters, runoff and groundwater containing NTO will be generated. Little is known about the fate of NTO during biological wastewater treatment. The objective of this study was to explore the ability of wastewater sludges to promote the biotransformation of NTO. Three different sludges, i.e., anaerobic granular sludge, anaerobic digested sludge, and return activated sludge, were used to study the biotransformation of NTO under anaerobic conditions. Three different electron donor amendments were compared- hydrogen, ethanol, and acetate. Mixed microbial communities in each of the three sludge sources were effective in the reductive biotransformation of NTO. 3-amino-1,2,4-triazol-5-one (ATO) was observed as the major product of NTO biotransformation. The highest maximum specific rate of NTO reduction, about 120 mg NTO/g volatile suspended solids/d, was observed in anaerobic granular sludge with hydrogen or ethanol supplied as electron donors. NTO biotransformation to ATO by anaerobic digested sludge was also studied under denitrifying conditions. In this case, reduction of NTO started only after complete denitrification of added nitrate. An important implication of this paper is that sludge from wastewater treatment plants can rapidly and readily reduce NTO to ATO. [GRAPHICS] .

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.

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.
