You could be based in a university, combining chemical research with teaching; in a pharmaceutical company, working on developing and trialing new drugs; helping to ensure national healthcare provision keeps pace with new discoveries. 88-44-8, Name is 4-Aminotoluene-3-sulfonic acid, SMILES is O=S(C1=CC(C)=CC=C1N)(O)=O, belongs to phthalazine compound. In a document, author is Aguilo, Joan, introduce the new discover, Computed Properties of https://www.ambeed.com/products/88-44-8.html.

Much attention has been paid to heterocyclic N-containing ligands due to their applicability as bridging ligands in the synthesis of redox active dinuclear metal complexes. With this aim, we report the synthesis and full characterization of a novel phthalazine-triazole ligand (1,4-bis(1-methyl-1H-1,2,3-triazol-4-yl) phthalazine). Moreover, we show that the phthalazine nitrogen atoms of this N-heterocyclic ligand are more reactive towards alkylating agents than the triazole groups. New ruthenium(II) complexes containing this ligand have been obtained and characterized both structurally and electrochemically. The geometry imposed by the ligand allows the placement of two ruthenium centers in very close proximity so that efficient through-space interactions take place, a concept of crucial importance for electron transfer processes.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

A new series of pyrazolo[1,2-b]phthalazine derivatives (4a-p) bearing the 5-aryloxypyrazole nucleus was synthesized by one-pot, three-component, base-catalyzed cyclo condensation reaction of 3-methyl-5-aryloxy-1-aryl-1H-pyrazole-4-carbaldehyde (1a-d), malononitrile or ethyl cyanoacetate (2a-b) and 2,3-dihydro-1,4-phthalazinedione (3a-b) in ethanol containing an eco friendly base, NaOH, in good to excellent yields.

Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 139-66-2, Name is Diphenylsulfane, molecular formula is C12H10S, belongs to phthalazine compound, is a common compound. In a patnet, author is Soliman, Saied M., once mentioned the new application about 139-66-2, SDS of cas: 139-66-2.

A new Schiff base derived from the antihypertensive hydralazine (LH) and its Co(III) complexes [CoL2] X*4H(2)O, where X = NO3 (1) or Cl (2), were synthesized and characterized using FTIR, UV-Vis,H-1 NMR spectroscopy as well as thermal analysis. The crystal structures of the three compounds have been determined using single crystal X-ray diffraction technique. The two complexes structure is strictly divided in a highly ordered part of the [CoL2](+) units and a disordered section containing the anions and sixteen crystal water molecules per unit cell. In the complexes, the two ligand anions (L-) chelate to the Co(III) through the nitrogen atoms in a tridentate meridional manner. The pyridine and phthalazine rings showed deviations from co-planarity in all compounds which attributed to the crystal packing effects as revealed by analysis of their molecular packing using Hirshfeld analysis and further supported by DFT calculations. The optimized structure of the [CoL2] NO3 as a model showed no co-planarity of the two rings while perfectly planar ligand units were predicted in the [CoL2](+) cation indicating that the intermolecular interactions with the nitrate counter anion have a major role in the deviations of the two ring moieties from planarity. The ligand anion (L-) optimized structure using B97D function which include dispersion model showed similar results while the functions (B3LYP and mPW1PW91) which include no dispersion model predicted perfectly planar arrangement. Atoms in molecules (AIM) studies predicted the strength of the Co-N interactions is in the order, Co-N(azomethine) > Co-N(phthalazine) > Co-N(pyridine) which are generally stronger in 2 than 1. The developmental toxicity of LH and its complexes were tested in zebrafish embryos. The ligand itself was very toxic with LC50 of just 2 mu M as compared to its metal complexes, whereas, at sub-lethal concentration the ligand perturbed the neurogenesis in zebrafish embryos.

Nitrogen atom containing heterocyclic compounds, pyridazines, pyridazinones and phthalazines are important structural feature of many biologically active compounds and show diverse pharmacological properties. Pyridazines and phthalazines hold considerable interest relative to the preparation of organic intermediates and physiologically active compounds. On the basis of literature, pyridazines, pyridazinone and phthalazines further focus our attention because of their easy fictionalization at various ring positions, which makes them attractive synthetic compounds for designing and development of the novel pyridazines and phthalazines drugs in future.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 14348-75-5, you can contact me at any time and look forward to more communication. Quality Control of 2,7-Dibromo-9H-fluoren-9-one.

In view of the anticonvulsant activity reported for phthalazine derivatives as non-competitive AMPA receptor antagonists, a new series of phthalazine-1,4-diones (2-12) were designed and synthesized. The neurotoxicity was assessed using rotarod test. The molecular docking was performed for the synthesized compounds to assess their binding affinities toward AMPA receptor as non-competitive antagonists. The molecular modeling data were strongly interrelated to biological screening data. Compounds 8, 7(b), 7(a), 10 and 3(a) exhibited the highest binding affinities as non-competitive AMPA receptor antagonists and also showed the highest relative potencies of 1.78, 1.66, 1.60, 1.59 and 1.29, respectively, as anticonvulsants in comparison with diazepam. The most active compounds 8, 7(b), 7(a), 10 and 3(a) were further tested against maximal electroshock seizure (MES). Compounds 8 and 7(b) and 3(a) showed 100% protection at a dose level of 125 mu gm/kg, while compounds 7(a) and 10 exhibited 83.33% protection at the same dose level. These agents exerted low neurotoxicity and high safety margin in comparison with valproate as a reference drug. Most of our designed compounds exhibited good ADMET profile.

In a document, author is Romero, Angel H..

With the aim to identify a potential drug candidate to treat cutaneous leishmaniasis, a series of 1-phthalazinyl hydrazones were synthesized and tested against Leishmania braziliensis parasite, one of the main responsible of this disease in the world. A structure-activity relationship permitted to identify two phthalazines containing nitroheterocyclic moiety 31 and 3m as promising new lead compounds. These compounds showed a significant antileishmanial activity against promastigote form of L. braziliensis, with EC50 values in sub-micromolar and nanomolar ranges. The phthalazine 31 also displayed a selective and excellent activity against the clinically relevant intracellular amastigotes form, with a EC50 value in sub-micromolar range (0.59 mu M), without affecting the viability of the host cells. Oxidative stress was identified as the possible mode of action of the most active phthalazine. Considering their significant antileishmanial activity and ease synthesis, the phthalazine containing nitroheterocyclic represents a promising agent against Leishmania braziliensis for the rational design of new leads.
