Let’s learn more about this compound (cas:1452-77-3).

The bifunctional photocatalytic-adsorbent AgZnO/polyoxometalates (AgZnO/POMs) nanocomposites were synthesized by combining AgZnO hybrid nanoparticles and polyoxometalates [Cu(L)2(H2O)]H2[Cu(L)2(P2Mo5O23)]·4H2O (HL = C6H6N2O) into nanostructures via a sonochem. method. Transmission electron microscopy (TEM) indicated that AgZnO/POMs nanocomposites were uniform with narrow particle size distribution and without agglomeration. X-ray powder diffraction (XRD) and XPS anal. confirmed the nanostructure and composition of AgZnO/POMs nanocomposites. The UV-visible spectra (UV-Vis) and photoluminescence spectra (PL) confirmed excellent optical properties of the AgZnO/POMs nanocomposites. 94.13% ± 0.61 of basic magenta (BM) in aqueous solution could be removed using the AgZnO/POMs nanocomposites through adsorption and photocatalysis. The kinetic anal. showed that both the adsorption and photocatalysis process conform to pseudo-second-order kinetics. In addition, the removal rate of AgZnO/POMs nanocomposites was found to be almost unchanged after 5 cycles of use. The bifunctional photocatalytic-adsorbent AgZnO/POMs nanocomposites with high stability and cycling performance have broad application prospects in the treatment of refractory organic dye wastewater containing triphenylmethane.

Author is Giese, Bernd; Deacon, Glen B.; Kuduk-Jaworska, Janina; McNaughton, Don.

There is considerable interest in the development of novel platinum-based anticancer drugs that overcome the disadvantages associated with the widely used drug cisplatin, which are its inactivity against some types of tumors and its toxic side effects. In this study we show the suitability of normal Raman spectroscopy (NRS) and surface enhanced Raman spectroscopy (SERS), assisted by d. functional theor. (DFT) calculations, for the characterization of Pt complexes. The Pt complexes studied include the established drugs cisplatin and carboplatin, as well as five novel Pt complexes with anticancer activity. DFT calculations at the B3LYP/LanL2DZ level are a good prediction of the exptl. NRS spectra of small and medium sized Pt complexes. The use of SERS allows the investigation of Pt complexes at physiol. concentrations, and the binding strengths of the different ligands can be determined The formation of pos. charged hydrolysis products may be necessary for SERS activity. The existing group in the hydrolysis reaction can be identified.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Supramolecular Nanoencapsulation as a Tool: Solubilization of the Anticancer Drug trans-Dichloro(dipyridine)platinum(II) by Complexation with β-Cyclodextrin, published in 2008-04-30, which mentions a compound: 15227-42-6, mainly applied to beta cyclodextrin trans dichlorodipyridine platinum complex nanoencapsulation solubilization anticancer, Quality Control of cis-Dichlorobis(pyridine)platinum(II).

A novel, water-soluble trans-platinum complex was synthesized by inclusion complexation with β-cyclodextrin. The complexation was confirmed by 1H NMR, FT-IR, TGA, and XRD as well as by SEM and EDX. As the precursor complex is not water-soluble, it is difficult to employ it for biol. applications. Here, we report that the encapsulation with cyclodextrin allowed to solubilize the complex to a solubility value of 1.6 mg/mL. Moreover, the cytotoxicity in vitro of the novel inclusion complex indicated a much higher activity after encapsulation.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 693-67-4, is researched, SMILESS is CCCCCCCCCCCBr, Molecular C11H23BrJournal, Article, Chemistry – A European Journal called Catalytic Asymmetric Fluorination of Copper Carbene Complexes: Preparative Advances and a Mechanistic Rationale, Author is Buchsteiner, Michael; Martinez-Rodriguez, Luis; Jerabek, Paul; Pozo, Iago; Patzer, Michael; Noethling, Nils; Lehmann, Christian W.; Fuerstner, Alois, the main research direction is copper carbene complex catalyst asym fluorination alpha diazoester; asymmetric catalysis; bisoxazoline ligands; carbene complexes; copper; organofluorine compounds.COA of Formula: C11H23Br.

The Cu-catalyzed reaction of substituted α-diazoesters with fluoride gives α-fluoroesters with ee values of up to 95%, provided that chiral indane-derived bis(oxazoline) ligands were used that carry bulky benzyl substituents at the bridge and moderately bulky iso-Pr groups on their core. The apparently homogeneous solution of CsF in C6F6/hexafluoroisopropanol (HFIP) is the best reaction medium, but CsF in the biphasic mixture CH2Cl2/HFIP also provides good results. DFT studies suggest that fluoride initially attacks the Cu- rather than the C-atom of the transient donor/acceptor carbene intermediate. This unusual step is followed by 1,2-fluoride shift; for this migratory insertion to occur, the carbene must rotate about the Cu-C bond to ensure orbital overlap. The directionality of this rotatory movement within the C2-sym. binding site determines the sense of induction. This model is in excellent accord with the absolute configuration of the resulting product as determined by x-ray diffraction using single crystals of this a priori wax-like material grown by capillary crystallization

The incidence of triple-neg. breast cancer (TNBC) is difficult to predict, and TNBC has a high mortality rate among women worldwide. A theranostics approach is developed for TNBC with ratiometric photoacoustic monitored thiol-initiated hydrogen sulfide (H2S) therapy. The ratiometric photoacoustic (PA) probe (CY) with a thiol-initiated H2S donor (PSD) to form a nanosystem (CY-PSD nanoparticles) is integrated. In this theranostics approach, H2S generated from PSD is sensed by CY based on ratiometric PA signals, which simultaneously pinpoints the tumor region. Addnl., H2S is cytotoxic toward TNBC cells (MDA-MB 231), showing a tumor inhibition rate of 63%. To further verify its pharmacol. mechanism, proteomics anal. was performed on tumors treated with CY-PSD nanoparticles. Cells are killed by the significant mitochondrial dysfunction via suppressed energy supply and apoptosis initiation. Besides, the observed inhibition of oxidative stress also generates the cytotoxicity. Significant Kyoto Encyclopedia of Genes Genomes pathways related to TNBC are inhibited. This H2S theranostics approach updates the current anticancer therapies which brings promise for women suffering malignant breast cancer.
