Synthesis, characterization, and anti-rheumatic potential of phthalazine-1,4-dione and its Cu(II) and Zn(II) complexes

Two new metal complexes derived from the reaction of 2-[(2-hydroxybenzoyl) 2,3,4a,5,10,10a-hexahydro-5,10[1′,2′]-benzenobenzo[g]phthalazine-1,4-dione] (HBPD) with Cu(II) and Zn(II) have been synthesized and characterized by using elemental analysis, spectral analysis (UV-Vis, IR, H-1 NMR, C-13 NMR), conductance, thermal analysis, and magnetic moments. The in vivo collagen-adjuvant arthritis model in rats revealed a significant antioxidant, analgesic, and anti-rheumatic effects for HBPD and its copper and zinc complexes in comparison with standard piroxicam. The results showed that, the investigated Cu and Zn complexes have higher anti-inflammatory activity than the free ligand.

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. 83-53-4, Name is 1,4-Dibromonaphthalene, formurla is C10H6Br2.

Synthesis, biological, anti-inflammatory activities and quantum chemical calculation of some [4-(2, 4, 6-trimethylphenyl)-1(2H)-oxo-phthalazin-2yl] acetic acid hydrazide derivatives

The phthalazine carbohydrazide 2 was prepared and incorporated into the corresponding 1,2,4-triazole and carbamate derivatives. Phthalazine carboxylic acid hydrazide 2 was treated with isatine and cyclohexanone to give the corresponding hydrazone derivatives 16,19 in good yields. Furthermore, cc-amino acid derivative conjugated with 1-oxophthalazine moiety 35 was synthesized by the reaction of the corresponding aizde 28, via the azide-coupling method, with glycine methyl ester. The peptide ester 35 was converted into their corresponding amide 36 by treating with methanolic ammonia. Moreover, 35 was boiled with hydrazine hydrate to afford the corresponding hydrazide 37. Finally, the dipeptide 38 was prepared by coupling of 35 with L-alanine methyl ester. Some of these compounds were screened in vitro for their antimicrobial activity. The energy gap between the highest occupied molecular orbital and lowest unoccupied molecular orbital has been calculated using the theoretical computations to reflect the chemical reactivity and kinetic stability of compounds.

delta-Regioselective heteroarylation of free alcohols through 1,5-hydrogen-atom transfer

An efficient silver-catalyzed d-regioselective C(sp(3))-H heteroarylation of free alcohols has been developed. Various alcohols reacted with quinolines, isoquinoline, pyridines, pyrimidine, phthalazine, 4-hydroxyquinazoline, acridine, quinoxaline and pyrazine to give the corresponding C(sp(2))-H alkylation products in 31-89% yields. Notably, all types (1 degrees, 2 degrees, and 3 degrees) of d-C(sp(3))-H bonds in the alcohols could be regioselectively activated. This protocol provides a platform to access divergent functionalizations of alcohols and heteroaryls by forming the challenging d-selective C(sp(3))-C(sp(2)) bond.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 83-53-4. SDS of cas: 83-53-4.

An effective phthalazine-imidazole-based chemosensor for detecting Cu2+, Co2+ and S2- via the color change

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.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 83-53-4, in my other articles. SDS of cas: 83-53-4.
