Copper(II) Schiff Base Complex with Electrocatalytic Activity Towards the Oxygen Reduction Reaction and Its Catalase Activity

The fuel cell is a continuously operating, low environmental impact, highly energy-efficient electrochemical device that has been cited as a clean energy source to replace fossil fuels. However, noble metals, such as platinum, are used as electrocatalysts to improve reaction kinetics, which raises the cost of this renewable energy source. This work aimed to evaluate a graphite paste electrode, modified with a copper(II) coordination compound containing N,O-donor groups, as an electrocatalyst in oxygen reduction reactions (ORR) and its catalase-like activity. Through electrochemical analyses, such as cyclic voltammetry and chronoamperometry, the modified electrode activity was investigated at different pH values and scan rates. Catalase activity was also investigated at different pH values in order to establish which would be the most active. The modified electrode proved to be a promising electrocatalyst in ORR in alkaline medium, and the copper(II) complex actively degraded hydrogen peroxide under alkaline conditions, which can help to increase the lifetime of the fuel cell device.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 288-88-0 help many people in the next few years. SDS of cas: 288-88-0.

Tris(5-phenyl-1H-1,2,4-triazolyl)iridium(III) Complex and Its Use in Blue Phosphorescent Organic Light-Emitting Diodes to Provide an External Quantum Efficiency of up to 27.8%

Although studies have investigated various N-heterocyclic-based Ir(III)-cyclometalates that exhibit high efficiency and electrochemical stability, blue-phosphorescent Ir(III) complexes with further improved efficiency and blue-emission purity are needed for use as emitters in organic light-emitting diodes (OLEDs). Therefore, the preparation and comprehensive characterization of a phenyl-1,2,4-triazole-based facial-homoleptic iridium(III) complex, TzIr (fac-tris(1-(2,6-diisopropylphenyl)-3-methyl-5-phenyl-1H-1,2,4 triazolyl)iridium(III)) is herein described. The complex shows a definite blue-emission band (lambda(em) = 456 nm) in the solution and film states at ambient temperature. Moreover, this complex exhibits considerably high phosphorescent quantum efficiency (80%) and thermal stability (T-d5 = 362 degrees C). Multilayer phosphorescent OLEDs using TzIr as the emitter and 3,3-di(9H-carbazol-9-yl)biphenyl (mCBP)/ 9-(3 ‘-(9H-carbazol-9-yl)-5-cyano-[1,1 ‘-biphenyl]-3-yl)-9H-carbazole-3-carbonitrile (CNmCBPCN) as the mixed host are fabricated. The devices exhibit outstanding performance, with a high external quantum efficiency (27.8%), current efficiency (38.7 cd A(-1)), and CIEy (y coordinate value of the Commission Internationale de l’Eclairage color space) less than 0.18. The results of this study indicate that this novel 1,2,4-triazole-based dopant, TzIr, is a promising candidate for developing highly efficient blue-phosphorescent emitters for use in OLEDs.

Quinoline-Proline, Triazole Hybrids: Design, Synthesis, Antituberculosis, Molecular Docking, and ADMET Studies

A series of novel quinoline-proline hybrids (11a-g) and quinoline-proline-1,2,3-triazole hybrids (12-14) were synthesized by click chemistry based on molecular hybridization concept and were characterized by NMR, mass spectrometry, and elemental analysis. All the titled target compounds were tested for antitubercular activity by MABA and LORA methods by in vitro. Interestingly, two compounds (2R,4S)-1-((2-cyclopropyl-4-(4-fluorophenyl)-quinolin-3-yl)-methyl)-4-(4-nitrobenzamido)-N-phenylpyrrolidine-2-carboxamide (11b) and (2R,4S)-1-((2-cyclopropyl-4-(4-fluorophenyl)-quinolin-3-yl)-methyl)-4-(4-fluorobenzamido)-N-phenylpyrrolidine-2-carboxamide (11c) exhibited significant activity against the tested Mycobacterium tuberculosis H37Rv strain. Further, the cytotoxicity (CC50) profile of the titled compounds against the Vero cell was performed and discussed. A molecular docking study of the hit compounds (11b and 11c) was also performed to find their putative binding interaction with the active site of the target proteins. Finally, in silico ADMET properties were also predicted for all the synthesized molecules to evaluate their drug-likeness behavior.

Safety and nonclinical and clinical pharmacokinetics of PC945, a novel inhaled triazole antifungal agent

PC945 is a novel antifungal triazole formulated for nebulized delivery to treat lung Aspergillus infections. Pharmacokinetic and safety profiles from nonclinical studies and clinical trials in healthy subjects, and subjects with mild asthma were characterized. Toxicokinetics were assessed following daily 2-hour inhalation for 14 days. Potential for drug-drug interactions was evaluated using pooled human liver microsomes. Clinical safety and pharmacokinetics were assessed following (a) single inhaled doses (0.5-10 mg), (b) 7-day repeat doses (5 mg daily) in healthy subjects; (c) a single dose (5 mg) in subjects with mild asthma. C-max occurred 4 hours (rats) or immediately (dogs) after a single dose. PC945 lung concentrations were substantially higher (>2000-fold) than those in plasma. PC945 only inhibited CYP3A4/5 substrate metabolism (IC50: 1.33 mu M [testosterone] and 0.085 mu M [midazolam]). Geometric mean C-max was 322 pg/mL (healthy subjects) and 335 pg/mL (subjects with mild asthma) 4-5 hours (median t(max)) after a single inhalation (5 mg). Following repeat, once daily inhalation (5 mg), Day 7 C-max was 951 pg/mL (0.0016 mu M) 45 minutes after dosing. Increases in C-max and AUC(0-24h) were approximately dose-proportional (0.5-10 mg). PC945 administration was well tolerated in both healthy subjects and subjects with mild asthma. Treatment-emergent adverse events were mild/moderate and resolved before the study ended. No clinically significant lung function changes were observed. PC945 pharmacokinetics translated from nonclinical species to humans showed slow absorption from lungs and low systemic exposure, thereby limiting the potential for adverse side effects and drug interactions commonly seen with systemically delivered azoles.
