A thermo-responsive copolymer with a gas-switchable LCST-type phase transition was synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization of N-isopropylacrylamide (NIPAM) and glycidyl methacrylate (GMA), followed by post-polymerization functionalization with sodium 3-amino-1,2,4-triazole (ATANa). Incorporating ionic moieties provides an elevated cloud point of 61 degrees C. Importantly, both CO2 and SO2 cause a reduction in the cloud point of the polymer solution. The CO2-triggered system can be easily and fully recovered to its initial state by introducing an inert gas (e.g. N-2), whereas the SO2-triggered system shows only partial recovery. The pH-dependent phase transition behaviors confirm that the gas bubbling-induced pH changes contribute to the gas-switchable cloud point of P(NIPAM-co-(GMA-ATANa)). In addition, P(NIPAM-co-(GMA-ATA)) (ATA: 3-amino-1,2,4-triazole), a counterpart of P(NIPAM-co-(GMA-ATANa)), was prepared and the relevant solution phase transition behavior was studied. Its cloud point shift in response to gas bubbling and pH adjustment is opposite to that of P(NIPAM-co-(GMA-ATANa)), indicating that the latter does not result from the protonation of amidine groups. Alternatively, a reversible H+-induced decrease in hydrophilicity was thus proposed. This contribution enriches the family of thermo-responsive polymers by introducing gas-sensitive polyelectrolytes and also broadens the scope of gas-responsive smart materials.

A novel pyridinium salt derivative, 2,3,4,5,6-pentaphenyl-1-(1H-1,2,4-triazol-3-yl)pyridinium perchlorate (1) has been designed and synthesized by using pyrylium perchlorate and 3-amino-1H-1,2,4-triazole as ingredients, which can be exploited for the binding and specific sensing of anion via hydrogen bonds. Compound 1 exhibits intense blue emission in solution with maximum emission at 469 nm with a red shift relative to that (426 nm) of solid state. The luminescence intensity of 1 could be selectively and sensitivity quenched with acetate ion and fluorine ion among various anions including F-, Cl-, Br-, I-, AcO- and NO3-. Furthermore, the possible detection mechanism was investigated. This work could contribute a credible potential sensing application of 1,2,4-triazolyl substituted pentaphenylpyridinium salts towards the specific anions in biological and environmental concerns.

Based on the extensive biological activities of thiazole derivatives against different types of diseases, we are interested in the effective part of many natural compounds, so we synthesized a new series of compounds containing di-, tri- and tetrathiazole moieties. The formation of such derivatives proceeded via reaction of 2-bromo-1-(4-methyl-2-(methylamino)thiazol-5-yl)ethan-1-one with heterocyclic amines, o-aminothiophenol and thiosemicarbazone derivatives. The structure and mechanistic pathways for all products were discussed and proved based on spectral results, in addition to conformational studies. Our aim after the synthesis is to investigate their antimicrobial activity against various types of bacteria and fungi species. Preceeding such an investigation, a molecular docking study was carried out with selected conformers, as representative examples, against three pathogen-proteins. This preliminary stage could support the biological application. The potency of these compounds as antimicrobial agents has been evaluated. The results showed that derivatives which have di- and trithiazole rings displayed high activity that exceeds the used standard antibiotic.

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.

The chemical behavior of 4,9-dimethoxy-5-oxo-5H-furo[3,2-g]-chromene-6-carbonitrile (khellin-6-carbonitrile) (1) was examined towards a variety of nitrogen nucleophiles. Some novel Schiff bases 5-7 were prepared from reaction of carbonitrile 1 with some heterocyclic amines. Treatment of carbonitrile 1 with some hydrazine derivatives in boiling ethanol afforded pyrazole derivatives 8-13. Khellin-6-carbonitrile (1) reacted with hydrazine hydrate and phenylhydrazine in acetic acid to afford angular heteroannulated furo[3′,2′:6,7]-chromeno [4,3-c]pyrazol-4(1H)-one derivatives 14 and 15. Triazolo[1,5-a]pyrimidine 16 and pyrimido[1,2-a]benzimidazole 17 were synthesized through ring opening and recyclization reactions of compound 1 with 3-amino-1,2,4-triazole and 2-aminobenzimidazole, respectively. Reaction of compound 1 with guanidine and cyanoguanidine in ethanolic potassium hydroxide solution resulted in ring conversion giving the novel angular furo [3 ‘,2’ :6,7] chromeno [4,3-d]pyrimidin-5-ones 18 and 19.

Neutrophil survival and oxidative stress during inflammatory conditions are linked to tissue damage. The present study explores less understood role of catalase, the enzyme catalysing hydrogen peroxide decomposition, in neutrophil survival/death. Importantly, inhibition of catalase activity following S-glutathionylation in the PMA, NO, or zymosan-activated neutrophils or treatment with catalase inhibitor led to neutrophil death. On the contrary, introducing reducing environment by TCEP rescued catalase activity and significantly improved neutrophil survival. Furthermore, augmentation in ROS generation by NOX-2 activation or induction of mitochondrial ROS by Antimycin-A induced catalase S-glutathionylation and cell death, which was prevented in the neutrophil cytosolic factor1 (NCF-1-/-) cells or was rescued by MitoTEMPO, a mitochondrial ROS scavenger, thus, suggesting a correlation between catalase S-glutathionylation/activity inhibition and reduced neutrophil survival. Altogether, enhanced NOX2 activation/mitochondrial dysfunction led to reduced survival of human and mice neutrophils, due to H2O2 accumulation, S-glutathionylation of catalase, and reduction in its enzymatic activity. The present study thus demonstrated mitigation of catalase activity under oxidative stress-impacted neutrophil survival.

In order to discover potential antitumor agents from natural products, chemical modifications of ergostane-type triterpenoids from Antrodia camphorata yielded ten new compounds. They include nine C-26 amide derivatives of antcin G (1) and a methyl antcin B (4) derivative with hydroxyamino groups at C-3 and C-7. Chemical structures of the new compounds were elucidated by NMR and MS analyses. Furthermore, cytotoxicities of the triterpenoid derivatives were evaluated using four human cancer cell lines (HL60, U251, SW480, and MCF-7). As a result, 1a, 1g, and 4a exhibited potent cytotoxic activities against HL60, U251, and SW480 with IC50 values of 0.7 +/- 0.9, 2.9 +/- 1.3, and 2.2 +/- 0.6 mu M, respectively. Molecular docking indicates that 1a, 1g, and 4a have strong binding affinity with DNA topoisomerase II alpha (-9.3, -7.9, and -7.4 kcal/mol, respectively), and that they could be potent topoisomerase II alpha inhibitors.

In this work, (Z)-N-benzoyl-N ‘-(1H-1,2,4-triazol-3-yl)carbamimidothioic acid and its Mn(II), Co(II), Cu(II) and Cd(II) complexes were introduced for the first time. This carbonyl thiourea ligand was prepared by the reaction of 1H-1,2,4-triazol-3-amine with benzoyl isothiocyanate. The structural elucidation of these compounds was performed using elemental analysis and spectral and magnetic measurements. Octahedral structures of all complexes, except Cd(II) complex with a tetrahedral geometry, were confirmed by applying DFT structural optimization. The thermal decomposition behaviour of metal complexes of carbonyl thiourea ligand is discussed. The calculation of kinetic parameters for prepared complexes (E-a, A, Delta H*, Delta S* and Delta G*) of all thermal degradation stages has been evaluated using two comparable approaches. Antimicrobial and ABTS-antioxidant studies indicated potent activity of Cd(II) complex compared with the other investigated compounds. The cytotoxic activity of the prepared compounds was investigated in vitro. The results indicated potent activity of Mn(II) complex against both HePG2 (liver carcinoma) and MCF-7 (breast carcinoma) cancer cells.

Chemical transformations of chromone-3-carbonitrile (1) with some substituted hydrazines, namely, thiosemicarbazide, S-methyl/benzyldithiocarbazate, 7-chloro-4-hydrazinoquinoline, and 3-hydrazino-5,6-diphenyl-1,2,4-triazine, led to substituted pyrazoles 2, 5-8. Ring opening of carbonitrile 1 followed by recyclization with 3-amino-1,2,4-triazole and 2-aminobenzimidazole gave triazolo[1,5-a]pyrimidine 9 and pyrimido[1,2-a]benzimidazole 10, respectively. Treatment of carbonitrile 1 with some heterocyclic amines produced 2-amino-3-substituted-chromones 11 and 12. The novel 3-hydroxychromeno[4,3-b]pyrazolo[4,3-e]pyridin-5(1H)-one (13) was efficiently synthesized from the ring conversion of carbonitrile 1 with cyanoacetohydrazide. A mixture of chromeno[2,3-b]naphthyridine 14 and chromeno[4,3-b]pyridine 15 was obtained from base catalyzed transformation of carbonitrile 1 with malononitrile dimer. A diversity of novel annulated chromeno[2,3-b]pyridines 16-22 was also synthesized. Chromeno[2,3-b]pyrrole-2-carboxylate 23 was obtained from the reaction of carbonitrile 1 with ethyl chloroacetate. Structures of the new synthesized products were deduced on the basis of their analytical and spectral data.
