One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 104-53-0, Name is 3-Phenylpropanal, formurla is C9H10O. In a document, author is Zhu, Mingfei, introducing its new discovery. Recommanded Product: 104-53-0.

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.

Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 104-53-0, Name is 3-Phenylpropanal, molecular formula is C9H10O, belongs to phthalazine compound, is a common compound. In a patnet, author is Hiiuk, Volodymyr M., once mentioned the new application about 104-53-0, Quality Control of 3-Phenylpropanal.

Two new 2D spin-crossover (SCO) analogues of Hofmann clathrates of composition [Fe(phth)(2)M-II(CN)(4)] (where phth = phthalazine; M-II = Pd, Pt) have been synthesized and their structures and switchable behaviour have been characterized. Single-crystal X-ray analysis reveals that the Pt and Pd derivatives contain Fe-II centres equatorially surrounded by four equivalent mu(4)-[M-II(CN)(4)](2-) groups. Two crystallographically equivalent phthalazine (phth) ligands occupy the axial positions of each Fe-II site, completing its octahedral coordination environment. The stabilization of these structures is realized via supramolecular C-HM interactions and pi-pi stacking. Temperature-dependent magnetic susceptibility measurements showed that Pt (T-1/2 down arrow = 211 K and T-1/2 up arrow = 218 K) and Pd (T-1/2 down arrow = 202 K and T-1/2 up arrow = 207 K) derivatives display cooperative spin crossover with narrow thermal hysteresis loops. In addition, spin crossover in these complexes was characterized by optical measurements, differential scanning calorimetry, and IR and Raman spectroscopy. This research shows that the use of phthalazine leads to the production of new SCO systems with attractive transition characteristics and opens up new perspectives for the design of switchable complexes based on fused bicyclic azine ligands.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 104-53-0, Name is 3-Phenylpropanal, molecular formula is C9H10O, belongs to phthalazine compound.

A novel and effective phthalazine-imidazole-based colorimetric chemosensor (E)-1-(2-((1H-imidazol-2-yl)me-thylene)hydrazinyl)phthalazine NNI was synthesized and tested to detect Cu2+ or Co2+ ions in buffer solution. NNI could probe Cu2+ and Co2+ by the color change from colorless to yellow. The complexation stoichiometries of NNI toward Cu2+ and Co2+ were, respectively, confirmed to be as 1:1 ratio and 2:1 by results of Job plot and ESI-mass. Detection limits of NNI for each metal showed 0.12 mu M and 65 nM which are lower than WHO guideline (31.5 mu M for Cu2+) and US Environmental Protection Agency (EPA) guideline (1.7 mu M for Co2+). Quantification of NNI for each metal was successful in real water samples. The Cu2+-NNI complex could detect S2- by demetallation with color change from yellow to colorless, and detection limit for S2- was determined as 0.80 mu M, which is lower than WHO guideline (14.8 mu M). Cu2+-NNI could detect S2- without interference when other anions coexisted. Detection of Cu2+, Co2+ and S2- among various metal ions and anions was successfully confirmed using test papers stained with NNI and Cu2+-NNI. Sensing processes of Cu2+, Co2+ and S2- by NNI were elucidated by UV-vis titration, ESI-mass, FT-IR, H-1 NMR titration and DFT calculations.

One-pot synthesis of 1,3,4-oxadiazole derivatives was achieved by treatment of 2-((4-(phenoxathiin-2-yl) phthalazin-1-yl)oxy) acetohydrazide with aromatic aldehydes in the presence of cerium(IV) ammonium nitrate in dichloromethane. This facile method was confirmed by the cyclization-oxidation reaction of the corresponding hydrazone by cerium(IV) ammonium nitrate to afford the same 1,3,4-oxadiazoles. Also, the reaction of 2-((4-(phenoxathiin-2-yl)phthalazin-1-yl) oxy) acetohydrazide with aromatic carboxylic acids in the presence of cerium(IV) ammonium nitrate in polyethylene glycol afforded 1,3,4-oxadiazole derivatives.

In the present study Cu(II)anchored onto the magnetic talc (gamma-Fe2O3/ talc /Cu(II)NPs) was successfully synthesized and characterized by FT-IR, XRD, TEM, FE-SEM, EDX, VSM, and ICP-OES techniques. Structural characterizations reveal that the gamma-Fe2O3/talc/Cu(II)NPs are superparamagnetic in nature, structured as a composite with average diameter of about 19-31 nm. The prepared nanostructured catalyst efficiently catalyzed the preparation of 1H-pyrazolo[1,2-b] phthalazine-5,10-diones at the gram scale without the use of the toxic organic solvents. The magnetically separable and environmentally friendly nanostructured catalyst remains quite stable during reaction conditions and reused for at least five recycle runs.
