The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, and theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states. 611-73-4, Name is 2-Oxo-2-phenylacetic acid, molecular formula is C8H6O3, belongs to phthalazine compound. In a document, author is Romero, Angel H., introduce the new discover, Computed Properties of https://www.ambeed.com/products/611-73-4.html.

1-Monosubstituted and 1,4-substituted phthalazins based on aryl/heteroarylhydrazinyl have demonstrated attractive antileishmanial profiles against amastigote forms of theLeishmania braziliensisparasite. Further optimization of the mentioned acyclic scaffold motivated us to design a series of 3-aryl-1,2,4-triazolo[3,4-a]phthalazines, cyclic versions of the phthalazins based on aryl/heteroarylhydrazinyl, which have not been evaluated againstLeishmaniaparasites yet. In order to compare to phthalazine-based aryl/heteroarylhydrazones, five essential 3-aryl-6-piperazin-1,2,4-triazolo[3,4-a]phthalazines were efficiently prepared in excellent yields (73-83%) through a facile one-pot procedure from 4-chloro-1-phthalazinyl-arylhydrazonesviaC-H dehydrogenative cyclization using silver(i) salt. Fromin vitroantileismanial evaluation, compound2d, a nitro derivative, was identified as the most promising agent with a good anti-amastigote response (IC50= 9.37 mu M) and low relative toxicity against peritoneal macrophages (LD50= 123.93 mu M). A moderate response was found against clinical amastigote isolates ofL. braziliensis, although superior compared to the reference glucantime. A comparison with their phthalazin analogues based on aryl/heteroarylhydrazinyl gave evidence that the efficacy of each chemical system is determined by the nature of the functionalization next to the aryl moiety, which suggests that different mechanisms of action are involved for each chemical system. The cyclized form led to an enhancement of the antileismanial activity compared to the acyclic form, but the nitroderivatives seemed to be highly more toxic than the parent non-cyclized compounds. From the three compared phthalazine groups, 4-chloro-1-phthalazine-(5-nitrofuryl)hydrazinil with a nanomolar antileishmanial response was identified as a promising lead for further optimization, whereas compound2demerges as a prominent hit platform to prepare a group of derivatives based on phthalazine-1,2,4-triazolo bearing 3-nitro-phenyl at the 3-position.

Aldehyde oxidase (AOX) is a xanthine oxidase (XO)-related enzyme with emerging importance due to its role in the metabolism of drugs and xenobiotics. We report the first crystal structures of human AOX1, substrate free (2.6-angstrom resolution) and in complex with the substrate phthalazine and the inhibitor thioridazine (2.7-angstrom resolution). Analysis of the protein active site combined with steady-state kinetic studies highlight the unique features, including binding and substrate orientation at the active site, that characterize human AOX1 as an important drug-metabolizing enzyme. Structural analysis of the complex with the noncompetitive inhibitor thioridazine revealed a new, unexpected and fully occupied inhibitor-binding site that is structurally conserved among mammalian AOXs and XO. The new structural insights into the catalytic and inhibition mechanisms of human AOX that we now report will be of great value for the rational analysis of clinical drug interactions involving inhibition of AOX1 and for the prediction and design of AOX-stable putative drugs.

Pathogenic fungi are one of the main causes of hospital-related infections. Since conventional antifungals have become less effective because of the increasing fungal resistance to the standard drugs, the need for new agents is becoming urgent. Herein we report a synthesis of a series of novel N-[imino-(1-oxo-(1H)-phthalazin-2-yl) methyl]benzenesulfonamide derivatives with in vitro activity against yeast-like fungi isolated from the oral cavity and respiratory tract of patients with candidiasis. These compounds were synthesized by the one-step or two-step reactions of 1-(2-alkylthiobenzensulfonyl)-2aminoguanidines with the appropriate ortho-carbonyl benzoic acids. The biological study revealed that new derivatives have shown significant growth-inhibitory activity, superior or comparable, than those of the reference drug fluconazole. The most promising activities were observed against Candida albicans, with inhibition at least 1-3 (12.5%-37.5%) of the eight tested strains at the low MIC level of <= 6.2-25 mu g/mL. 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 611-73-4, in my other articles.

Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 611-73-4, Name is 2-Oxo-2-phenylacetic acid, molecular formula is , belongs to phthalazine compound. In a document, author is Kon, Hiroki, Electric Literature of 611-73-4.

Two ternary ligands consisting of two 2,2′:6′,2 ”-terpyridines and one N4-quadridentate mu(2),eta(2)-bridging ligand were synthesized. The N4 bridge is 1,4-bis(2-pyridyl)phthalazine in ligand 1, and 3,6-bis(2-pyridyl)pyridazine in ligand 2. Two Co(II) dinuclear complexes [(1)Co-2(mu-OH)](3+) and [(2)Co-2(mu-OH)](3+), and one Ni(II) dinuclear complex [(1)Ni-2(mu-Cl)](3+) were obtained. In the crystal structures of [(1)Co-2(mu-OH)](3+) and [(1)Ni-2(mu-Cl)](3+), two pyridine rings are twisted around the pyridine-phthalazine bonds to avoid steric repulsion between the hydrogen atoms. The pyridine rings also showed a significant tilt from the octahedral coordination plane, which causes the large positive shift of the first reduction potentials. Upon the addition of a proton, the cobalt dinuclear complexes can release one cobalt ion selectively, and the dinuclear complexes can be easily restored by the addition of a tertiary amine.

In this paper, C-N bond formation between 2,3-dihydrophthalazine-1(4H),4-dione (phthalhydrazide) and alpha,beta-unsaturated esters was investigated and a new series of phthalazine derivatives was synthesized using an efficient and simple method under solvent-free conditions. An aza-Michael addition of phthalhydrazide to both acrylic and fumaric esters led to N-monosubstituted phthalhydrazides (as mono-Michael adduct) in the presence of tetrabutylammonium bromide as a high polar media, and 1,4-diaza-bicyclo[2,2,2] octane as an available organic base. In this reaction, the N1,N2-bis-Michael adduct was not observed at all. Also, reactions were performed at 90 degrees C and yields of products were good to excellent.
