Conjugated polymers are promising light harvesters for water reduction/oxidation due to their simple synthesis and adjustable bandgap. Herein, both cyanamide and triazole functional groups are first incorporated into a heptazine-based carbon nitride (CN) polymer, resulting in a mesoporous conjugated cyanamide-triazole-heptazine polymer (CTHP) with different compositions by increasing the quantity of cyanamide/triazole units in the CN backbone. Varying the compositions of CTHP modulates its electronic structures, mesoporous morphologies, and redox energies, resulting in a significantly improved photocatalytic performance for both H(2)and O(2)evolution under visible light irradiation. A remarkable H(2)evolution rate of 12723 mu mol h(-1)g(-1)is observed, resulting in a high apparent quantum yield of 11.97% at 400 nm. In parallel, the optimized photocatalyst also exhibits an O(2)evolution rate of 221 mu mol h(-1) g(-1), 9.6 times higher than the CN counterpart, with the value being the highest among the reported CN-based bifunctional photocatalysts. This work provides an efficient molecular engineering approach for the rational design of functional polymeric photocatalysts.

Background: Advanced glycation end products (AGEs) are known to be involved in the pathophysiology of diabetic complications, neurodegenerative diseases, and aging. Preventing the formation of AGEs can be helpful in the management of these diseases. Objectives: Two classes of previously synthesized traizole Schiff’s bases (4H-1,2,4-triamle-4-Schiff’s bases 1-14, and 4H-1,2,4-triazole-3-Schiff’s bases 15-23) were evaluated for their in vitro antiglycation activity. Methods: In vitro fructose-mediated human serum albumin (HSA) glycation assay was employed to assess the antiglycation activity of triazole Schiff’s bases. The active compounds were subjected to cytotoxicity analysis by MTT assay on mouse fibroblast (3T3) cell line. Molecular docking and simulation studies were carried out to evaluate the interactions and stability of compounds with HSA. Anti-hyperglycemic and antioxidant activities of selected non-cytotoxic compounds were evaluated by in vitro a-glucosidase inhibition, and DPPH free radical scavenging assays, respectively. Results: Compound 1 (IC50 =47.30 +/- 0.38 mu M) from 4H-1,2,4-triazole-4-Schiff’s bases has exhibited antiglycation activity comparable to standard rutin (IC50 =54.5 +/- 0.05 mu M) along with a stable RMSD profile in MD simulation studies. Compound 1 also exhibited a potent a-glucosidase inhibitory activity, and moderate antioxidant property. Other derivatives showed a weak antiglycation activity with IC50 values between 248.1-637.7 mu M. Compounds with potential antiglycation profile were found to be non-cytotoxic in a cellular assay. Conclusion: The study identifies triazole Schiff s bases active against fructose-mediated glycation of HSA, thus indicates their potential against late diabetic complications due to production of advancedend products (AGEs).

Drug-like inhibitors are often designed by mimicking cofactor or substrate interactions with enzymes. However, as active sites are comprised of conserved residues, it is difficult to identify the critical interactions needed to design selective inhibitors. We are developing an approach, named RADD (resistance analysis during design), which involves engineering point mutations in the target to generate active alleles and testing compounds against them. Mutations that alter compound potency identify residues that make key interactions with the inhibitor and predict target-binding poses. Here, we apply this approach to analyze how diaminotriazole-based inhibitors bind spastin, a microtubule-severing AAA (ATPase associated with diverse cellular activities) protein. The distinct binding poses predicted for two similar inhibitors were confirmed by a series of X-ray structures. Importantly, our approach not only reveals how selective inhibition of the target can be achieved but also identifies resistance-conferring mutations at the early stages of the design process.

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.

The viscosity of neat ionic liquids is very important for their application in organic synthesis as a solvent because most of the neat ionic liquids are very viscous, which would result in the less efficient mass transfer of reactants. In the present study, a series of novel dihydro-[1,2,4]triazolo[1,5-a]pyrimidines were prepared using a low viscous and acid-functionalized ionic liquid. Our results showed that new ionic liquid can act as a green solvent and acid catalyst due to low viscosity and acid functionality. The products were simply extracted and the ionic liquid was retrieved several times without reducing its catalytic efficiency. The current application of TMDPS in the one-pot multicomponent reactions as dual solvent-catalyst highlights the importance of low viscous acid-functionalized ionic liquids in organic synthesis, and we hope that further research will be conducted in the future to finding other applications of TMDPS with promising results.

Based on the previous studies that revealed the valuable role of pyrazole scaffold in cancer management and VEGFR-2 inhibition, a new set of pyrazole conjugated with pyrazoline, triazolopyrimidine and pyrazolone moieties were synthesized and investigated for their anticancer efficiency against human breast cancer MCF-7. The anticancer screening revealed the significant sensitivity of breast carcinoma towards compounds 4b, 5c, 6c, 7b, 7c and 12c with IC50 values ranging from 16.50 – 26.73 mu M in comparison with tamoxifen (IC50 = 23.31 mu M). Moreover, the new analogues were further examined for their VEGFR-2 inhibitory activity, among the tested derivatives 5c, 6c, 7b, 7c and 12c displayed prominent inhibitory efficiency versus VEGFR-2 kinase with % inhibition ranging from 70 to 79%. Compounds 6c, 7c and 12c revealed inhibitory efficiency in nanomolar level with IC50 (913.51, 225.17 and 828.23 nM, respectively) comparing to sorafenib (IC50 = 186.54 nM). Flow cytometric analysis revealed that the promising compound 12c prompted pre-G1 apoptosis and cell growth cessation at G2/M phase and stimulated apoptosis via activation of caspase-3. Moreover, molecular docking study of the promising derivatives was performed to highlight their binding modes and interactions with the amino acid residues of VEGFR-2 enzyme.

Treatment of 3-methylcyclohexanone with ethyl formate in the presence of sodium methoxide afforded sodium (2-methyl-6-oxocyclohexylidene)methanolate which reacted with aminopyrazoles, aminotriazole, and aminotetrazole to produce fused quinazoline derivatives; its reactions with cyanothioacetamide, cyanoacetamide, and cyanoacetohydrazide gave tetrahydroquinoline-3-carbonitrile derivatives. The reactions of 8-methyl-2-sulfanyl-5,6,7,8-tetrahydroquinoline-3-carbonitrile with alkylating agents led to the formation of thieno[2,3-b]quinoline derivatives. DFT computational studies of the synthesized compounds were carried out using B3LYP/6-311+G** and HF/6-311+G** approximations. The calculated HOMO and LUMO energies showed that charge transfer occurs in their molecules.

N-doped carbon nanopipe-arrayed mesoporous carbon (N-CMK-5) with double-pore system, large surface area (992 m(2)/g), and high nitrogen amount (5.2 at.%) was synthesized by a simplified template route. In this route, mesoporous silica was directly used instead of using time-consuming aluminosilicate as a template and the carbonization process occurred in a nitrogen atmosphere instead of a vacuum. Furthermore, CMK-3, N-doped CMK-3, and CMK-5 ordered mesopomus carbons (OMCs) were compared with the as-prepared N-doped CMK-5 (N-CMK-5) to investigate the effect of microstructure on the electrochemical activity of OMCs. N-CMK-5 exhibited higher electrochemical activity than the other OMCs because it has more exposed defective sites and nitrogen active species. The developed N-CMK-5-based electrochemical sensor showed good practical application for the electrochemical detection of pesticide amitrole in real water sample. This work contributes a simplified route to synthesize tubular N-CMK-5 carbon and provides valuable information on the design of high-performance carbon electrode materials.
