2,3-Bifunctionalized quinoxalines: Synthesis, DNA interactions and evaluation of anticancer, anti-tuberculosis and antifungal activity

A variety of 2,3-bifunctionalized quinoxalines (6-14) have been prepared by the condensation of 1,6-disubstituted-hexan-1,3,4,6-tetraones (1-4) with o-phenylenediamine, (R,R)-1,2-diaminocyclohexane and p-nitro-o-phenylenediamine. It is concluded that strong intramolecular N-H-O bonds in the favoured keto-enamine form may be responsible for the minimal biological activities observed in DNA footprinting, anti-tubercular, anti-fungal and anticancer tests with these hyper pi-conjugated quinoxaline derivatives. However, subtle alteration by addition of a nitro group affecting the charge distribution confers significant improvements in biological effects and binding to DNA.

A general and mild Ullmann-type synthesis of diaryl ethers

(Equation presented) An efficient method for the synthesis of diaryl ethers under particularly mild conditions is described. Inexpensive ligands were found to greatly accelerate the Ullmann-type coupling of aryl bromides or iodides with phenols. A series of diaryl ethers were obtained with excellent yields in acetonitrile in the presence of Cs2CO3 and catalytic copper(I) oxide. The reaction tolerates substrates with unfavorable substitution patterns, such as sterically hindered coupling partners or electron-rich aryl halides.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.SDS of cas: 1436-59-5. In my other articles, you can also check out more blogs about 1436-59-5

Molybdenum(VI) cis-dioxo complexes with chiral schiff base ligands: Synthesis, characterization, and catalytic applications

Three optically active Molybdenum (VI) dioxo complexes with tetrahydro salen and substituted tetrahydro salen derivatives as ligands were synthesized and examined as catalysts for asymmetric epoxidation. Complexes of the type MoO2(L)(Solv) and WO2(L) (L = tridentate, trans-2-aminocyclohexanol derived chiral Schiff base, Solv = alcohol) were prepared and characterized by elemental analysis, NMR and IR spectroscopy. These complexes are applicable as catalysts for olefin epoxidation reactions with tert-butyl hydroperoxide (TBHP) being the oxidizing agent. In case of cis-beta-methylstyrene moderate enantiomeric excesses of up to 26% can be reached when the reaction is carried out at 0C.

A novel water-soluble highly selective ?switch-on? ionic liquid-based fluorescent chemi-sensor for Ca(II)

A novel chemi-sensor involve new bis-ionic Schiff base sensor (BISBS), N,N?-bis-[5-((2,4-lutidiniumchloride)methylene)-3-methoxysalicylidene]-R,R-1,2-cyclohexanediimine, has been synthesized and characterized. BISBS chemi-sensor was designed based on internal charge transfer (ICT) fluorescence mechanism. This new water soluble chemi-sensor provides great selectivity fluorescence detection for Ca(II) ions in an important physiological pH range. Moreover, the interaction of Ca(II) with the deprotonated BISBS to produce a metal-ligand complex with a ratio of (1: 1) accompanying with an enhancement in the intensity of emission band located at 502?nm. Fluorescence switching-on during the chemical interaction between BISBS and Ca(II) ions is very easily noticed with naked eye, but other metal cations such as alkali, alkaline earth and transition metal don’t give any fluorescence changes. The novel developed BISBS sensor successively offers low limit of detection (LOD) 1.5?nM and fast tracing of Ca(II) in the physiological pH?7.6. Thus BISBS may provide a novel auspicious methodology for detection calcium cations in the environmental and biological samples.

Supramolecular assemblies from ditopic ligands and transition metal salts

Tetradentate salicylaldimine ligands of the H2salen-type bearing ort/io-A’-morpholinomethyl substituents function as ditopic ligands, bonding to Ni” or Cu” with the [N2O2]2″ donor set of the salen unit and a sulfate or two nitrate anions with the protonated morpholine units. The binding of the metal salt by the zwitterionic form of the ligand provides a novel approach to the transport of metal sulfates in metal recovery processes. A comparison of the solid state structures of a “free” ligand with a series of nickel(n) complexes demonstrates that the metal ion templates the ligand system, orientating the pendant morpholinium groups to form electrostatic and bifurcated hydrogen bonds in the sulfate complex to the dianion creating a neutral 1:1:1 [LMZ+X2] complex suitable for extraction into water immiscible solvents. Other binding modes involving bridging of metal complex units by anion binding to the pendant morpholine groups suggest that these ditopic ligands could also be used to assemble unusual three-dimensional arrays of metal complexes in the solid state.

A systematic study of the interactions between chemical partners (metal, ligands, counterions, and support) involved in the design of Al 2O3-supported nickel catalysts from diamine-Ni(II) chelates

1.5 Ni wt %/Al2O3 catalysts have been prepared by incipient wetness impregnation using [Ni(diamine)x(H 2O)6-2x]Y2 precursors (diamine = 1,2-ethanediamine (en) and trans-1,2-cyclohexanediamine (tc); x = 0, 1, and 2; Y = NO3- and Cl-), to avoid the formation, during calcination, of difficult-to-reduce nickel aluminate. N2 was chosen for thermal treatment to help reveal and take advantage of the reactions occurring between Ni2+, ligands, counterions, and support. In the case of [Ni(en)2(H2O)2]Y2 salts used as precursors, in situ UV-vis and DRIFT spectroscopies show that after treatment at 230AC Ni(II) ions are grafted to alumina via two OAl bonds and that the diamine ligands still remain coordinated to grafted nickel ions but in a monodentate way, bridging the cation with the alumina surface. With Y = Cl-, the chloride counterions desorb as hydrogen chloride, and hydrogen released upon decomposition of the en ligands is able to reduce a fraction of nickel ions into metal as evidenced by XPS. In contrast, with Y = NO3-, compounds such as CO or NO are formed during thermal treatment, indicating that nitrate ions burn the en ligands. After thermal treatment at 500AC, a surface phase containing Ni(II) ions forms, characterized by XPS and UV-vis spectroscopy. Temperature-programmed reduction shows that these ions can be quantitatively reduced to the metallic state at 500AC, in contrast with the aluminate obtained when the preparation is carried out from [Ni(H2O)6]2+, which is reduced only partly at 950AC. On the other hand, a total self-reduction of nickel complexes leading to 2-5-nm metal particles is obtained upon thermal treatment via the hydrogen released by a hydrogen-rich ligand such as tc, whatever the Y counterion. An appropriate choice of the ligand and the counterion allows then to obtain selectively Ni(II) ions or a dispersed reduced nickel phase after treatment in N2, as a result of the reactions occurring between the chemical partners present on alumina.

Nano-zinc coordination with the ligands of carboplatin, oxaliplatin and nedaplatin. Synthesis, characterization and biological properties

The replacement of platinum in carboplatin, oxaliplatin and nedaplatin by zinc metal (in bulk and nano-scalled) produces biologically active compounds with increased solubility in water. We compared, in this work, three synthesized zinc-complexes from the ligands of platinum-anticancer drugs. The structural characterization of the products has been determined on the basis of their atomic absorption spectroscopy, elemental analysis, FT-IR, 1H and 13C NMR spectra. The crystalline structure and morphology of the products have been shown by XRD and SEM techniques. The antibacterial activities of the complexes have been examined through the growth inhibitory zone and minimal inhibitory concentrations.
