A novel pyrazolone-based copper complex [CuL(phen)(CH3OH)][CuL(phen)]·CH3CH2OH·CH3OH (P-FAH-Cu-phen) was synthesized and characterized. The asym. structural unit of P-FAH-Cu-phen was composed of two independent complex units [CuL(phen)(CH3OH)] and [CuL(phen)]:Cu12+ center with six coordination mode and Cu22+ center with five coordination mode. The growth of BEL-<7404≥ cells and H22 cells was significantly inhibited by P-FAH-Cu-phen with IC50 values of 1.175μg/mL and 1.097μg/mL, resp., which were much lower than IC50 of cisplatin for BEL-<7404≥ cells (23.32μg/mL) and H22 cells (27.5μg/mL). P-FAH-Cu-phen induced cell cycle arrest at G2/M and apoptosis in BEL-<7404≥ cells through mitochondria- and endoplasmic reticulum stress-associated pathways. Moreover, P-FAH-Cu-phen significantly suppressed the migration of BEL-<7404≥ cells and the tumor growth in H22 tumor mouse model without severe side effects and improved the survival of tumor mice. The results suggested that P-FAH-Cu-phen might be a potential drug candidate for the treatment of live cancer.

Formula: C5H6N2O2. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 2-Furoic hydrazide, is researched, Molecular C5H6N2O2, CAS is 3326-71-4, about Chemistry of mixed-ligand oxidovanadium(IV) complexes of aroylhydrazones incorporating quinoline derivatives: Study of solution behavior, theoretical evaluation and protein/DNA interaction.

A series of eight hexacoordinated mixed-ligand oxidovanadium(IV) complexes [VO(Lx)(LN-N)] (1-8), where Lx = L1 – L4 are four differently substituted ONO donor aroylhydrazone ligands and LN-N are N,N-donor bases like 2,2′-bipyridine (bipy) (1, 3, 5 and 7) and 1,10-phenanthroline (phen) (2, 4, 6 and 8), are reported. All synthesized complexes were characterized by various physicochem. techniques and mol. structures of 1 and 6 were determined by x-ray crystallog. With a view to evaluate the biol. activity of the VIVO species, the behavior of the systems VIVO2+/Lx, VIVO2+/Lx/bipy and VIVO2+/Lx/phen was studied as a function of pH in a mixture of H2O/DMSO 50/50 (volume/volume). DFT calculations allowed finding out the relative stability of the tautomeric forms of the ligands, and predicting the structure of vanadium complexes and their EPR parameters. To study their interaction with proteins, firstly the ternary systems VIVO2+/L1,2 with 1-methylimidazole, which is a good model for histidine binding, were examined Subsequently the interaction of the complexes with lysozyme (Lyz), cytochrome c (Cyt) and bovine serum albumin (BSA) was studied. The complexes showed moderate binding affinity towards BSA, while no interaction takes place with lysozyme and cytochrome c. This could be explained with the higher number of accessible coordinating and polar residues for BSA than for Lyz and Cyt. Further, the complexes were also evaluated for their DNA binding propensity through UV-visible absorption titration and fluorescence spectral studies. These results were consistent with BSA binding affinity and showed moderate binding affinity towards CT-DNA.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2-Furoic hydrazide, is researched, Molecular C5H6N2O2, CAS is 3326-71-4, about Kinetic and mechanistic analysis of oxidation of 2-furoic hydrazide by hexachloroirradate(IV) in a wide pH range.Computed Properties of C5H6N2O2.

Oxidation of 2-furoic hydrazide (FH) by hexachloroiridate(IV) ([IrCl6]2-) was studied kinetically in a wide pH range in aqueous solution of 1.0 M ionic strength. The oxidation reaction followed well-defined second-order kinetics: – d[IrCl62-]/dt = k'[FH]tot[IrCl62-], where [FH]tot denotes the total concentration of FH and k’ stands for the observed second-order rate constants The established k’-pH profile displays that k’ increases drastically with pH and a plateau region exists between pH 4 and 6. A stoichiometric ratio of Δ[FH]tot/Δ[IrCl62-] = 1/4 was revealed by spectrophotometric titrations 1H NMR spectroscopic studies indicated that FH was cleanly oxidized to 2-furoic acid. The kinetic data suggest a reaction mechanism in which all the three protolysis species of FH react with [IrCl6]2- in parallel, forming the rate-determining steps. Two stabilized hydrazyl radicals are generated in the rate-determining steps, in which a single electron is transferred to [IrCl6]2-. The two hydrazyl radicals react rapidly in consecutive steps requiring 3 mol of Ir(IV) to form 2-furoic acid as the final product. Rate constants of the rate-determining steps were deduced through a simulation of the rate expression to the k’-pH dependency data. Values of these rate constants demonstrate that the three protolysis species of FH have a huge reactivity span, changing by about 109 times toward reduction in [IrCl6]2- and that FH can be readily oxidized in neutral and basic media. Rapid scan spectra and the measured activation parameters suggest that an outer-sphere electron transfer is probably taking place in each of the rate-determining steps. This is the first kinetic study on the oxidation reactions of FH and provides concurrently the protolysis constants of FH (pKa1 = 3.04 ± 0.08 and pKa2 = 11.6 ± 0.1) at 25.0 °C and 1.0 M ionic strength.
