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).

The insufficient intracellular H2O2 level in tumor cells is closely associated with the limited efficacy of chemodynamic therapy (CDT). Despite tremendous efforts, engineering CDT agents with a straightforward and secure H2O2 supplying ability remains a great challenge. Inspired by the balance of H2O2 generation and elimination in cancer cells, herein, a nanozyme-based H2O2 homeostasis disruptor is fabricated to elevate the intracellular H2O2 level through facilitating H2O2 production and restraining H2O2 elimination for enhanced CDT. In the formulation, the disruptor with superoxide dismutase-mimicking activity can convert O-2(center dot-) to H2O2, promoting the production of H2O2. Simultaneously, the suppression of catalase activity and depletion of glutathione by the disruptor weaken the transformation of H2O2 to H2O. Thus, the well-defined system could perturb the H2O2 balance and give rise to the accumulation of H2O2 in cancer cells. The raised H2O2 level would ultimately amplify the Fenton-like reaction-based CDT efficiency. Our work not only paves a way to engineer alternative CDT agents with a H2O2 supplying ability for intensive CDT but also provides new insights into the construction of bioinspired materials.

Intracerebroventricular (icv) injection of hydrogen peroxide (H2O2), a reactive oxygen species, or the blockade of catalase (enzyme that degrades H2O2 into H2O and O-2) with icv injection of 3-amino-1,2,4-triazole (ATZ) reduces the pressor effects of angiotensin II also injected icv. In the present study, we investigated the effects of ATZ injected icv or intravenously (iv) on the pressor responses induced by icv injections of the cholinergic agonist carbachol, which similar to angiotensin II induces pressor responses that depend on sympathoexcitation and vasopressin release. In addition, the effects of H2O2 icv on the pressor responses to icv carbachol were also tested to compare with the effects of ATZ. Normotensive non-anesthetized male Holtzman rats (280-300 g, n = 8-9/group) with stainless steel cannulas implanted in the lateral ventricle were used. Previous injection of ATZ (5 nmol/1 mu l) or H2O2 (5 mu mol/1 mu l) icv similarly reduced the pressor responses induced by carbachol (4 nmol/1 mu l) injected icv (13 +/- 4 and 12 +/- 4 mmHg, respectively, vs. vehicle + carbachol: 30 +/- 5 mmHg). ATZ (3.6 mmol/kg of body weight) injected iv also reduced icv carbachol-induced pressor responses (21 +/- 2 mmHg). ATZ icv or iv and H2O2 icv injected alone produced no effect on baseline arterial pressure. The treatments also produced no significant change of heart rate. The results show that ATZ icv or iv reduced the pressor responses to icv carbachol, suggesting that endogenous H2O2 acting centrally inhibits the pressor mechanisms (sympathoactivation and/or vasopressin release) activated by central cholinergic stimulation.

For the first time, the coordination-based energy sacrificial bonds have been constructed in the interface between lignin and polyolefin elastomer for preparing a new class of high performance thermoplastic elastomers (TPEs) with biomass lignin as the hard plastic phase. The coordination bonds not only promoted the dispersion of lignin, but also improved the interfacial interactions between lignin and polyolefin elastomer matrix, and also facilitated the orientation of chain segments during stretching. The synergistic coordination effect of lignin promoted higher energy dissipation, leading to simultaneously enhanced strength and toughness of lignin-based TPEs even with the lignin loading as high as 30 wt %. The lignin-based TPEs also exhibited excellent shape memory performance. Our strategy offers a promising methodology for the facile production of high performance but cost-effective TPE materials using biorenewable resources as plastic phase.

Six novel ruthenium(III) complexes of general formula [RuCl3(L)(3)] (1,3,5) and [RuCl3(H2O)(L)(2)] (2,4,6), where L stands for three different triazolopyrimidine-derived ligands, are reported. The compounds have been structurally characterized (IR, EPR, SCXRD), and their magnetic moments have been determined. The single-crystal X-ray diffraction study revealed a slightly distorted octahedral geometry of the Ru(III) complexes with mer configuration in 1 and 5, and fac configuration in 3. In 2 and 4, three chloride ions are in mer configuration and the two triazolopyrimidines are oriented trans mutually with the water molecule playing the role of the sixth ligand. All complexes have been thoroughly screened for their in vitro cytotoxicity against human breast cancer cell line MCF-7, human cervical cancer cell line HeLa, and L929 murine fibroblast cells, uncovering among others that the most lipophilic complexes 5 and 6, containing the bulky ligand dptp (5,7-diphenyl-1,2,4-triazolo[1,5-a]pyrimidine), display high cytotoxic activity against MCF-7, and HeLa cells. Moreover, it was also revealed that during the interaction of the complexes 1-6 with the cancer MCF-7 cell line, reactive oxygen species are released intracellularly, which could indicate that they are involved in cell apoptosis. Furthermore, extensive studies have been carried out to reveal the mechanism by which complexes 1-6 interact with DNA, albumin, and apotransferrin. The biological studies were complemented by detailed kinetic studies of the hydrolysis of the complexes in the pH range 5-8, to determine the stability of the complexes in solution. Graphic abstract Six novel ruthenium(III) complexes with triazolopyrimidine derivatives demonstrated the potential for use as anticancer agents by maintaining the toxic effect on MCF-7 and HeLa cells.

We report in this work the synthesis, crystal structures analyses, and nonlinear-optical (NLO) properties of three Schiff bases with halogens and triazole moieties: (E)-1-(4-bromophenyl)-N-(1H-1,2,4-triazol-3yl)methanimine L1, (E)-1-(4-bromophenyl)-N-(4H-1,2,4-triazol-3-yl)methanimine L2, and (E)-1-(4chlorophenyl)-N-(4H-1,2,4-triazol-3-yl)methanimine L3. The three molecules are built on the basis of the same backbone formed by two aromatic rings (phenyl and triazole) linked by imine bridge. The two first compounds L1 and L2 contain tautomers of the Schiff base, where a phenyl ring is substituted by a bromine atom. The third one, L3, is similar to L2 but contains a chlorine atom instead of bromine. In crystals formed by these three Schiff bases the three dimensional networks are formed by supramolecular interactions such as hydrogen bonds, C-X…pi and X…X (X = Cl or Br) contacts. Complementary Hirshfeld surface analyses were carried out to investigate and quantify the contributions of the different intermolecular interactions within the supramolecular assemblies. These analyses reveal that the main contributions in the studied compounds are provided by the H center dot center dot center dot H and N center dot center dot center dot H interactions that represent-53% (for L1),-49% (for L2) and-50% (for L3) of the total contributions to the Hirshfeld surface. The nonlinear optical properties are investigated by nonlinear diffuse femtosecond-pulse reflectometry and are compared with those of the reference material LiNbO3, in particular regarding the temporal evolution.
