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.

ATP-sensitive potassium (K-ATP) channels and transient receptor potential melastatin 2 (TRPM2) channels are commonly expressed both pre- and postsynaptically in the central nervous system (CNS). We hypothesized that K-ATP and TRPM2 may couple metabolic status to the resting membrane potential of octopus neurons of the mouse ventral cochlear nucleus (VCN). Therefore, we studied the expression of K-ATP channels and TRPM2 channels in octopus cells by immunohistochemical techniques and their contribution to neuronal electrical properties by the electrophysiological patch clamp technique. In immunohistochemical staining of octopus cells, labelling with Kir6.2 and SUR1 antibodies was strong, and labelling with the SUR2 antibody was moderate, but labelling with Kir6.1 was very weak. Octopus cells had intense staining with TRPM2 antibodies. In patch clamp recordings, bath application of KATP channel agonists H2O2 (880 mu M), ATZ (1 mM), cromakalim (50 mu M), diazoxide (200 mu M), NNC 55-0118 and NN 414 separately resulted in hyperpolarizations of resting potential to different extents. Application of 8-Bro-cADPR (50 mu M), a specific antagonist of TRPM2 channels, in the presence of H2O2 (880 mu M) resulted in further hyperpolarization by approximately 1 mV. The amplitudes of H2O2-induced outward K-ATP currents and ADPR-induced inward currents were 206.1 +/- 31.5 pA (n = 4) and 136.8 +/- 22.4 pA, respectively, at rest. Their respective reversal potentials were -77 +/- 2.6 mV (n = 3) and -6.3 +/- 2.9 (n = 3) and -6.3 +/- 2.9 (n = 3). In conclusion, octopus cells appear to possess both K-ATP channels and TRPM2-like channels. K-ATP might largely be constituted by SUR1-Kir6.2 subunits and SUR2-Kir6.2 subunits. Both K-ATP and TRPM2-like channels might have a modulatory action in setting the membrane potential.

A new promising protocol has been developed for the synthesis of scarce oxocine derivatives 3a-e and 6 through addition of amine-based nucleophiles such as hydroxylamine hydrochloride, primary amine and hydrazide to chromonylidene benzothiazol-2-ylacetonitrile 2 in refluxing dioxane under metal free reaction conditions in moderate to good yields. Other nitrogen nucleophiles such as piperidine, hydrazine and thiosemicarbazide failed to afford the corresponding oxocinols, and instead pyridine derivatives 7, 8 and 10 were obtained exclusively. Predictive study for the biological activities using PASS (prediction of activity spectra for biologically active substances) online software showed optimistic activities for oxocinols 3a-e in the treatment of cancer, influenza A and microbial infections. Additionally, DFT studies of oxocine derivatives 3a-e and 6 indicated the presence of required thermodynamics parameters for the application in dye-sensitized solar cells (DSSCs).

The CAS is 61-82-5. Through research, I have a further understanding and discovery of 1H-1,2,4-Triazol-5-amine.

Aims and Objectives: An efficient and facile DBU catalysed synthesis of highly significant motif 5,7-disubstituted-1,2,4-triazolo[1,5-a]pyrimidines under solvent-free condition has been reported. Materials and Methods: To a round bottom flask, 1.0 mmol of chalcone (1), 1.5 mmol of 3-amino-1,2,4-triazole (2) and 30 mol% of DBU were added at 70 degrees C and stirred in solvent-free condition. After the completion of the reaction (monitored by TLC), water (10 ml) was added. The aqueous layer was extracted with ethyl acetate (3 x 10 ml). The combined organic layers were dried over anhydrous Na2SO4. The combined organic layers were evaporated under reduced pressure and the resulting crude product was purified by column chromatography by using ethyl acetate and hexane as eluent. Results: Reaction using chalcone and 3-amino-1,2,4-triazole as model substrates were carried out under different reaction conditions and it was observed that 30 mol% of DBU under the solvent-free condition at 70 degrees C was the optimum temperature for the proposed synthesis. Conclusion: Use of DBU (an organocatalyst) as a base, operational simplicity, high yield of products and short reaction time are some of the significant advantages associated with the proposed strategy.

Co-crystals are emerging as members of supramolecular family having particular practical and fundamental significance for chemists, crystallographers, pharmaceutical scientists, and theoreticians. The presented study is focused to synthesize anti-cancer co-crystals of commercially available nandrolone (1), a synthetic anabolic-androgenic steroidal drug. Co-crystallization is done using economical and green grinding and reflux methods to obtain nandrolone (Nan): salicylic acid (Sal) and nandrolone (Nan): 3-amino-1,2,4-triazole (Triz) co-crystals, in 2:1 and 1:1 stoichiometric ratios, respectively. The structural analysis and characterization were carried out using single-crystal X-ray diffraction, and vibrational spectroscopy. Nandrolone (1) crystallizes in monoclinic P2(1) space group, while the co-crystal-I (Nan:Sal) and co-crystal-II (Nan:Triz), co-crystallized in the orthorhombic P2(1)2(1)2(1) space group. The intermolecular hydrogen bonds O-H center dot center dot center dot O, C-H center dot center dot center dot O, N-H center dot center dot center dot O, O-H center dot center dot center dot N, and N-H center dot center dot center dot N between the active pharmaceutical ingredient (nandrolone) and co-formers (salicylic acid, and 3-amino-1,2,4-triazole) stabilize the structures of cocrystals. In vibrational spectroscopy of co-crystal-I (Nan:Sal), the blue shifts in stretching frequencies of hydroxyl group from 3417.9 cm(-1) to 3427.8 cm(-1) further supported the hydrogen bond interactions between API and co-former. Similarly, in co-crystal-II (Nan:Triz) the NH2 stretching frequency from 3331.4- 3413.4 cm(-1) to 3312.7 cm(-1), supported the interaction of NH2 with API via intermolecular interaction. Nandrolone (1) and both co-crystals were found to be non-cytotoxic against 3T3 normal fibroblast cell line. Nandrolone (IC50 = 1.0 0.1 mu M), co-crystal-I (Nan:Sal) (IC50 = 1.6 +/- 0.3 mu M) and-II (Nan:Triz) (IC50 = 1.8 +/- 0.1 mu M) showed anti-cancer potential against cervical cancer HeLa cell line. While doxorubicin (IC50 = 1.2 +/- 0.2 mu M) was used as standard tested compound. SYNOPSIS Two new non-cytotoxic co-crystals of synthetic anabolic-androgenic steroidal drug nandrolone (Nan) with pharmaceutically acceptable salicylic acid (Sal), and triazole (Triz) were synthesized and their structures were elucidated using single-crystal X-ray diffraction, and vibrational spectroscopy. Quantitative analysis of -OH and -NH2 intermolecular interactions between API and co-former by Hirshfeld surface analysis further supported the role of various functionalities towards the stability of co-crystals. Both co-crystals were found to be non-cytotoxic against 3T3 normal fibroblast cell line. Co-crystal-I (Nan:Sal) and co-crystal-II (Nan:Triz) were found to be selectively active against HeLa cancer cell line (IC50 = 1.6 +/- 0.3 mu M), (IC50 = 1.8 +/- 0.1 mu M). (c) 2020 Elsevier B.V.

A colorimetric and visual assay is described for the herbicide aminotriazole (ATZ). It is based on the etching of gold nanorods (AuNRs) by iodine which is formed on oxidation of iodide via H2O2. Longitudinal etching of the AuNRs occurs quickly and is accompanied by a color change from dark blue to red. In the absence of ATZ and the presence of active catalase (CAT), H2O2 is quickly decomposed into water, and the AuNRs will not be etched. In thepresence of ATZ, CAT is partially deactivated, and this affects the amount of available H2O2 and, consequently, of the iodine. Hence, the color is significantly changed. The color changes can be easily detected with bare eyes. The assay has a linear response in the 5 to 70 mu M concentration range, with a detection limit of 1.3 mu M and high selectivity for ATZ. It was applied to the determination of ATZ in water and food samples.
