Chemiluminescence (CL) of a cyclometallated iridium (III) complex {tris[1-(2,6-dimethylphenoxy)-4-(4-chlorophenyl)phthalazine]iridium(III)} in the presence of potassium permanganate and oxalic acid is reported for the first time. Cysteine exhibits sufficient enhancing effect on the CL generated from the cyclometallated iridium(III) complex, which make it possible for the sensitive detection of cysteine using a flow-injectionchemiluminescence (FICL) method. The optimum conditions for the chemiluminescence emission were investigated. Under the optimal condition, the linear range for the determination of cysteine was 1.0?x?1095.0?x?106?mol/L with a detection limit of 6.9?x?1010?mol/L. A relative standard deviation of 1.6% was obtained for eight replicate determinations. The mechanisms of CL are proposed and the emitting species was identified as the metal-to-ligand charge-transfer (MLCT) excited states of the iridium complex.

Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 54381-16-7, Name is 2,2′-((4-Aminophenyl)azanediyl)diethanol sulfate, molecular formula is C10H18N2O6S.

Tropical diseases currently constitute a major health problem and thus a challenge in the field of drug discovery. The current treatments show serious disadvantages due to cost, toxicity, long therapy duration and resistance, and the use of metal complexes as chemotherapeutic agents against these ailments appears to be a very attractive alternative. Herein, we describe three newly synthesized ruthenium complexes with a bioactive molecule, the purine analogue 5,6,7-trimethyl-1,2,4-triazolo[1,5-a]pyrimidine (tmtp): cisfactRuCl(2)(clinso)(3)(tmtP)] (1), mer-[RuCl3(dmso)(H2O)(tmtp)]center dot 2H(2)O (2) and fac,cis-[RuCl3(H2O)(tmtp)(2)] (3). Their structures were characterized using X-ray and spectroscopic methods (IR, NMR or EPR). The stability of the synthesized complexes 1-3 in various buffered solutions (pH = 3-7.4) was monitored using conventional and stopped-flow techniques. The in vitro antiproliferative activity of all ruthenium complexes against promastigote forms of Leishmania spp. (L. infarztum, L. braziliensis, and L. donovani) and epimastigote forms of Trypanosoma cruzi was investigated. Notably, the results showed that the activity of 1 against L. brasiliensis was more than three-fold higher than that of glucantime, and 1 showed no appreciable toxicity towards J774.2 macrophages. Additionally, 2 displayed even 141-fold lower toxicity against host cells than glucantime, demonstrating significantly higher selectivity than the reference drug. Therefore, 1 and 2 appear to be excellent candidates for further development as potential drugs for the effective treatment of leishmaniasis and Chagas disease. All novel complexes were also shown to be potent inhibitors of Fe-SOD in the studied species, while their effects on human CuZn-SOD were very low.

The understanding and control of proton transfer reactions between acid-base pairs in the solid state are two of the main challenges for the crystal engineering community. The ability to control proton transfer reactions in the solid state enables a more selective preparation of cocrystals and salts, which facilitates the design of solid materials with specific physicochemical properties. In this study, an approach to control proton transfer reactions of an E-butenedioic acid/phthalazine cocrystal-salt (hybrid) system is presented, which allows the selective formation of its cocrystal and salt. In this approach the dominant intermolecular interactions between acid-base pairs are identified. Such interactions appear to be crucial for the inhibition or promotion of proton transfers in the solid state. For this, the relationship between these interactions and the so-called ApKa rule has been investigated.

10-(1-Phthalazinylazo)-9-phenanthrol (HL, I) was synthesized by the reaction between 1-hydrazinophthalazine and 9,10-phenanthrenequinone. The crystal and molecular structures of compound I were determined by X-ray diffraction (XRD). According to XRD, EAS, and H-1 and C-13 NMR data, a HL molecule in solutions and in crystals exists in the form of quinohydrazone tautomer (b) (s-trans, cis) stabilized by intramolecular N(3)H…O(1) hydrogen bond. The mobile H atom is localized at the N(3) atom of the azo group. The phthalazine (A) and phenanthrenequinone (B) moieties of the HL molecule are nearly coplanar. The HL basicity and acidity constants (pK(a) = 1.90 and pK(a) = 11.65, respectively) and the formation constants of HL complexes with Zn2+ and Cd2+ and their compositions in solutions were determined. ML2 center dot DMFA complexes, where M = Zn2+, Cd2+, were synthesized. The coordination mode of the L- ligand with metal atoms was suggested.

Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 371-42-6, Name is 4-Fluorothiophenol, molecular formula is , belongs to phthalazine compound.

Four new complex compounds of bis(phthalazine-1-hydrazone)-2,6-diacetylpyridine (Hz(2)DAP) ligand with Ni-II, Co-III, Cu-II and Zn-II metal centres were synthesised and characterised by single-crystal X-ray diffraction and IR spectral data. The antimicrobial activity of Hz(2)DAP and the obtained complexes [Co(Hz(2)DAP-H)Cl-2]center dot MeOH, [Ni(Hz(2)DAP-H)]Cl center dot MeOH, [Cu(Hz(2)DAP-H)Cl] and [Zn(Hz(2)DAP-2H)]center dot H2O were tested in vitro against selected Gram(-) and Gram(+) bacterial strains and fungi. The antimicrobial activity of the ligand is negligible, while its complexes with Ni-II, Co-III and Cu-II show considerable activity against Escherichia coli, Staphylococcus aureus and Micrococcus lysodeikticus. On the contrary, [Zn(Hz(2)DAP-2H)]center dot H2O promotes the growth of Candida albicans, while its antibacterial activity is negligible. On the basis of thermal data and those from coupled TG/MS measurements the decomposition mechanisms were determined and evaluated. (C) 2014 Elsevier Ltd. All rights reserved.

A novel chemiluminescence (CL) system, including the cyclometallated iridium(III) complex {tris[1-(2,6-dimethylphenoxy)-4-(4-chlorophenyl)phthalazine]iridium}, potassium permanganate and oxalic acid, is proposed for the determination of benzenediols. This method is based on the fact that hydroquinone and catechol exhibited an inhibiting effect, while resorcinol exhibited an enhancing effect on CL intensity. The optimum conditions for CL emission were investigated. Under optimal conditions, the detection limits of hydroquinone, catechol and resorcinol were 6.4?x?10-8, 2.7?x?10-9 and 8.1?x?10-7?mol/L, respectively. The method has been successfully applied to the determination of benzenediols in different types of water sample. The luminophors of the CL systems were all identified as the metalligand charge-transfer (MLCT) excited state of the iridium complex. Copyright (c) 2011 John Wiley & Sons, Ltd.

This report presents the single crystal X-ray structures of several substituted isoindolines that have been frequently used as starting materials for phthalocyanines, phthalocyanine analogs and related chelates. The structures of 1,3-diiminoisoindoline (1), 1,3-bis(hydroxyimino) isoindoline (2), 1,4-diaminophthalazine (3), 1,1,3-trichloroisoindoline (4) and 3-imino-1-oxoisoindoline (5) are reported; compounds 2 and 3 are synthesized from diiminoisoindoline (1) and 4 and 5 are produced from phthalimide. All five compounds are planar macrocycles, and localization of double bonds can be readily determined. We elucidated one of the known structures of 1 at low temperature, and observed two additional new structures of 1. For the crystal forms of 1 and compounds 2, 3, and 5, hydrogen bonding in the solid state was observed. Compounds 1, 2 and 3 form extended hydrogen bonded arrays in the solid state, whereas 5 forms discrete hydrogen bonded dimers.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 495-69-2. Recommanded Product: 2-Benzamidoacetic acid.
