The synthesis of 1H-indazolo[1,2-b]phthalazine-1,6,11(13H)-trione derivatives, using one-pot three-component condensation reaction of 3-nitrophthalic anhydride, hydrazine monohydrate, dimedone, and aromatic aldehydes in the presence of ZrO(NO3)(2).2H(2)O as the novel catalyst and in reflux conditions in EtOH was reported. Quantum theoretical calculations for three structures of compounds (5a, 5b, and 5c) were performed using the Hartree-Fock (HF) and density functional theory (DFT). From the optimized structure, geometric parameters were obtained and experimental measurements were compared with the calculated data. The structures of the products were confirmed by IR, H-1 NMR, C-13 NMR, mass spectra, and elemental analyses. The IR spectra data and H-1 NMR and C-13 NMR chemical shift computations of the 1H-indazolo[1,2-b]phthalazine-1,6,11(13H)-trione derivatives in the ground state were calculated. Frontier molecular orbitals (FMOs), total density of states (DOS), thermodynamic parameters, and molecular electrostatic potential (MEP) of the title compounds were investigated by theoretical calculations. Molecular properties such as the ionization potential (I), electron affinity (A), chemical hardness (eta), electronic chemical potential (mu), and electrophilicity (omega) were investigated for the structures. Thus, there was an excellent agreement between experimental and theoretical results.

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 7524-50-7, in my other articles.

Piperazine rings are important heterocyclic targets in organic synthesis and are useful synthetic intermediates or intricate parts of biologically active molecules. In our efforts, a series of piperazine derivatives has been prepared discovering new classes of antimicrobial agents, including bis(phthalimido)piperazine, bis(3-aminopropyl) piperazine, 2,3-dihydro-phthalazine-1,4-dione, and bis(3,4-aminophenol)piperazine. The synthesized antimicrobial agents have been studied using various spectroscopic techniques. Furthermore, these compounds have been screened for their in vitro antimicrobial activity against selected bacterial and fungal strains. Three compounds exhibited mild to good antibacterial activity, but somewhat lower antifungal activity against tested microbial strains.

Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 7524-50-7, Name is H-Phe-OMe.HCl, molecular formula is C10H14ClNO2, belongs to phthalazine compound, is a common compound. In a patnet, author is Yu, Hai-Ling, once mentioned the new application about 7524-50-7, Product Details of 7524-50-7.

Background: QUAN-0808 (6-(4-chlorophenoxy)-tetrazolo[5,1-a]phthalazine), a new phthalazine tetrazole derivative, was evaluated for the anti-inflammatory and analgesic effects. Methods: Xylene-induced ear edema, carrageenan (Carr)-induced paw edema, and acetic acid-induced capillary permeability hyperactivity in mice were used to assess the anti-inflammatory effect; acetic acid-induced writhing and hot plate responses for the analgesic activity. Results: In the present study, QUAN-0808 (100, 200, 400 mg/kg) and indomethacin (Indo) significantly decreased xylene-induced ear edema by 33.3, 37.5, 46.6, and 45.1%, respectively, decreased Carr-induced paw edema at 1, 2, 4 h after Carr injection, and decreased the prostaglandin E-2 (PGE(2)) and nitric oxide (NO) levels on the edema paw at 4 h after Carr injection; QUAN-0808 (100, 200,400 mg/kg), and aspirin (Asp, 200 mg/kg) significantly decreased Evans blue exudation in acetic acid-induced capillary permeability hyperactivity model by 26.7, 28.7, 32.3 and 29.1%, respectively, and decreased the numbers of acetic acid-induced writhing response in 15 min by 40.4, 53.6, 66.4, and 64.5%, respectively. Morphine (10 mg/kg) significantly increased the latency of the hot plate response by 136.5, 117.4, 67.5, and 22.7%, respectively, at 30, 60, 90, 120 min after intraperitoneal injection of morphine; however, QUAN-0808 (100, 200 and 400 mg/kg) did not produce significantly antinociceptive effects in the hot plate test, suggesting that its antinociceptive action occurs via peripheral rather than a central-acting mechanism. Conclusions: These results show that QUAN-0808 produced potential anti-inflammatory and peripheral antinociceptive effects, and indicated that the antinociceptive effects of QUAN-0808 were related to its anti-inflammatory activity in a dose-dependent manner. Therefore, as inflammation is a peripheral process, it is suggested that QUAN-0808 exerted peripheral effects. The peripheral effect mechanisms of QUAN-0808 may be related to a decrease in the production of PGR(2), NO, bradykinin and other inflammatory mediators.
