A SO3H-bearing carbonaceous solid catalyst has been synthesized through sulfonation followed by the hydrothermal carbonization method from renewable resource polyethylene glycol. The biodegradable catalyst was characterized by XRD, TEM, FT-IR, and energy dispersive X-ray. The surface area and pore diameter of the catalyst were determined by a nitrogen adsorption-desorption isotherm experiment. A highly efficient multicomponent heteroannulation protocol for the synthesis of a library of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives has been developed by applying the solid acid catalyst. This synthesis was established to follow the group-assistant-purification chemistry process avoiding traditional chromatography.

In a patnet, author is Xin, Lijun, once mentioned the new application about 523-27-3.

Two near-infrared-(NIR-) emitting cationic iridium(III) complexes, [Ir(dpbpa)(2)(Bphen)]+PF6- (1) and [Ir(dtbpa)(2)(Bphen)]+PF6- (2), were rationally designed and synthesized, where dpbpa, dtbpa, and Bphen represent 1,4-diphenylbenzo[g]-phthalazine, 1,4-di(thiophen-2-yl)benzo[g]phthalazine and 4,7-dipheny1,10-phenanthroline, respectively. By using highly conjugated cyclometalated benzo[g]phthalazine ligands, these two complexes exhibited a significantly large red shift in wavelength to the truly NIR region with maximum peaks at 715 nm for 1 and 775 nm for 2. Complex 1 exhibited unexpectedly improved quantum efficiency up to 6.1% in the solid films. Based on these solution-processable phosphors, NIR organic-light-emitting devices (OLEDs) have been fabricated and demonstrated negligible efficiency roll-off with nearly constant external quantum efficiency around 0.5% over a wide range of current density of 1-100 mA cm(-2). Density functional theory calculations were performed to discover that the newly cyclometalated benzo[g]phthalazine ligands have several areas of superiority over the previous benzo[g]quinoline ligands in views of stronger Ir-N bonds, smaller chelate congestion, higher electron-accepting ability, thus improving the overall phosphorescence of the corresponding iridium complexes in the NIR region.

Having gained chemical understanding at molecular level, chemistry graduates may choose to apply this knowledge in almost unlimited ways, as it can be used to analyze all matter and therefore our entire environment., Application of 523-27-3, 523-27-3, Name is 9,10-Dibromoanthracene, SMILES is BrC1=C2C=CC=CC2=C(Br)C3=CC=CC=C13, belongs to phthalazine compound. In a document, author is Zhu, Mingfei, introduce the new discover.

Inhibition of aberrant Hedgehog (Hh) pathway had been proved to be a promising therapeutic intervention in cancers like basal cell carcinoma (BCC), medulloblastoma (MB), and so on. Two drugs (Vismodegib, Sonidegib) were approved to treat BCC and more inhibitors are in clinical investigation. However, the adverse effects and drug resistance restricted the use of Hh inhibitors. In the present study, 61 synthesized compounds containing central backbone of phthalazine or dimethylpyridazine were screened as candidates of new Hh signaling inhibitors by performing dual luciferase reporter assay. Among the compounds, L-4 exhibited an IC50 value of 2.33 nM in the Shh-Light II assay. L-4 strongly inhibited the Hh pathway in vitro and blocked the Hh pathway by antagonizing the smoothened receptor (Smo). Remarkably, L-4 could significantly suppress the Hh pathway activity provoked by Smo mutant (D473H) which showed strong resistant properties to existing drugs such as Vismodegib. Orally administered L-4 exhibited prominent dose-dependent anti-tumor efficacy in vivo in Ptch+/-; p53-/- MB allograft model. Furthermore, L-4 showed good tolerance in acute toxicity test using ICR mice. These evidences indicated that L-4 was a potent, well-tolerated, orally active inhibitor of Hedgehog pathway, and might be a promising candidate in development of Hh-targeted anti-cancer drugs.

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 science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, Recommanded Product: 9,10-Dibromoanthracene, 523-27-3, Name is 9,10-Dibromoanthracene, SMILES is BrC1=C2C=CC=CC2=C(Br)C3=CC=CC=C13, belongs to phthalazine compound.

Common marmosets (Callithrix jacchus), New World monkeys, are a promising primate model for preclinical drug metabolism studies because of the similarities of cytochrome P450 (P450) enzyme function to those of humans. Despite an increasing number of drug candidates catalyzed by non-P450 enzymes, drug metabolizing enzymes other than P450s have been hardly identified or characterized in marmosets. In this study, we identified aldehyde oxidase (AOX) 1 gene by marmoset genome analysis. AOX1 cDNA was cloned from marmoset livers by reverse transcription-polymerase chain reaction. Deduced amino acid sequences of AOX1 cDNA showed high sequence identities (92-93%) with primate AOX1s. Phylogenetic analysis showed that marmoset AOX1 was closely clustered with primate AOX1s, unlike nonprimate animal model AOX1s of pig, rabbit, rat, and mouse used in drug metabolism. The tissue expression analyses by real-time reverse-transcription polymerase chain reaction and immunoblotting showed that marmoset AOX1 mRNA and protein were abundantly expressed in livers, similar to cynomolgus monkeys and humans. Marmoset AOX1 heterologously expressed in Escherichia coli catalyzed the oxidation of carbazeran and phthalazine, typical AOX1 substrates, similar to cynomolgus monkey and human AOX1s. Human and marmoset AOX1 effectively catalyzed phthalazine oxidation when assessed with Michaelis-Menten kinetics, but cynomolgus monkey AOX1 catalyzed this reaction with cooperative kinetics with high capacity. These results indicated that tissue distribution and enzymatic function of AOX1 enzyme is similar between marmosets and humans, suggesting that marmosets are a suitable primate model for AOXdependent drug metabolism in preclinical studies.

A series of 11-molybdo-1-vanadophosphoric acid supported on montmorillonite K-10 catalysts were prepared and characterized by FT-IR spectroscopy, thermal analysis, XRD, BET and SEM analysis techniques. Characterization data reveals the chemical immobilization of H4PMo11V1O40 catalyst on the montmorillonite K-10 support. The catalytic performance of synthesized catalysts was investigated for the synthesis of 2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione derivatives by one-pot three-component reaction of phthalhydrazide, dimedone and aromatic aldehydes under solvent-free conditions. Among different catalysts, 20% H4PMo11V1O40 supported on to montmorillonite K-10 showed the highest catalytic activity. Effect of reaction parameters such as catalyst loading, temperature and the nature of substituents on the aromatic ring of aldehydes were also evaluated. The protocol developed using H4PMo11V1O40/K-10 has several distinct advantages such as operational simplicity, short reaction time, high yield, reusable catalyst and preclusion of toxic solvent.
