Fish scale hydroxyapatite (FS-HAP) has been used as an efficient catalyst for the synthesis of 3-amino-1H-pyrazolo[1,2-b]phthalazine-2-carboxamide derivatives via the one-pot, three-component cyclocondensation reactions of aromatic aldehydes with cyanoacetamide and phthalhydrazide under solvent-free condition. FS-HAP has been characterized by FT-IR, XRD, SEM and EDS techniques. The synthesized compounds were evaluated for their in vitro antibacterial activity against gram-positive (Bacillus cereus, Bacillus aryabhattai, Bacillus megaterium, Staphylococcus aureus) and gram-negative (Serratia marcescens, Bacillus Pseudomonas putida, Escherichia coli, Enterobacter cloacae) bacteria. Tetracycline and erythromycin were used as standard antibiotics in this investigation. In the present protocol, we have achieved remarkable yields of the product in shorter reaction time and the catalyst was easily recovered and reused.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 62-23-7, Name is 4-Nitrobenzoic acid, molecular formula is C7H5NO4. In an article, author is Eldehna, Wagdy M.,once mentioned of 62-23-7, Formula: https://www.ambeed.com/products/62-23-7.html.

A series of anilinophthalazine derivatives 4a-j was initially synthesized and tested for its VEGFR-2 inhibitory activity where it showed promising activity (IC50 = 0.636-5.76 mu M). Molecular docking studies guidance was used to improve the binding affinity for series 4a-j towards VEGFR-2 active site. This improvement was achieved by increasing the hydrophobic interaction with the hydrophobic back pocket of the VEGFR-2 active site lined with the hydrophobic side chains of Ile888, Leu889, Ile892, Val898, Val899, Leu1019 and Ile1044. Increasing the hydrophobic interaction was accomplished by extending the anilinophthalazine scaffold with a substituted phenyl moiety through an uriedo linker which should give this extension the flexibility required to accommodate itself deeply into the hydrophobic back pocket. As planned, the designed uriedo-anilinophthalazines 7a-i showed superior binding affinity than their anilinophthalazine parents (IC50 = 0.083-0.473 mu M). In particular, compounds 7g-i showed IC50 of 0.086, 0.083 and 0.086 mu M, respectively, which are better than that of the reference drug sorafenib (IC50 = 0.09 mu M). (C) 2016 Elsevier Masson SAS.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 143-66-8, Name is Sodium tetraphenylborate, molecular formula is C24H20BNa, belongs to phthalazine compound. In a document, author is Shalkouhi, Somaye Nikzad, introduce the new discover, HPLC of Formula: https://www.ambeed.com/products/143-66-8.html.

The surface of Fe3O4 magnetic nanoparticles (MNPs) was modified by L-cysteine through condensation of COOH groups of L-cysteine and OH groups on the surface of Fe3O4. The -SH group of prepared Fe3O4@Cys MNPs oxidized to -SO3H group and Fe3O4@Cys-SO3H as an environmentally friendly magnetic nanoparticle was prepared. The MNPs were characterized by FT-IR, XRD, SEM and TEM studies. Then, the catalytic activity of the MNPs was evaluated as an effective and reusable catalyst for one-pot synthesis of 2H-indazolo [1,2-b] phthalazine-triones derivatives. The results show that the catalytic activity of Fe3O4@Cys-SO3H was comparable to that of other reported heterogeneous and homogeneous catalysts.

Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , HPLC of Formula: https://www.ambeed.com/products/1878-68-8.html, 1878-68-8, Name is 4-Bromophenylacetic acid, molecular formula is C8H7BrO2, belongs to phthalazine compound. In a document, author is Im, Jeong Kyun, introduce the new discover.

A rarely explored oxidative ring contraction of electron-rich 1,2-diazine is described. Upon treatment with an electrophilic chlorinating reagent (TCICA), 1,4-dimethoxyphthalazines undergo an N-chlorination-induced ring contraction that is accompanied by the loss of one nitrogen atom. The scope of this unusual reactivity was examined with a range of 1,4-dimethoxyphthalazine derivatives. In addition, a mechanism proceeding via a bicyclic species was proposed on the basis of an isolated reaction intermediate and DFT calculations. (C) 2020 Elsevier Ltd. All rights reserved.
