An efficient and rapid one-pot multicomponent synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones through condensation of aldehyde, malononitrile and phthalhydrazide catalyzed by agro-waste solvent catalyst-derived water extract of mango peel ash (WEMPA) under microwave irradiation is described. Further, the catalyst is prepared from agricultural waste and characterized for elemental composition by different techniques such as SEM-EDX, XRD and flame photometry. This green synthetic approach offers various advantages such as inexpensive, abundantly available source, shorter reaction time (6-8 min), good-to-excellent yield (83%-89%), simple workup and a sustainable alternative method to the existing protocols. All the synthesized compounds (4a-l) was confirmed by FT-IR,H-1-NMR,C-13-NMR and LC-MS.

Electric Literature of 886-86-2, As a society publisher, everything we do is to support the scientific community – so you can trust us to always act in your best interests, and get your work the international recognition that it deserves. 886-86-2, Name is Ethyl 3-aminobenzoate methanesulfonate, SMILES is O=C(OCC)C1=CC=CC(N)=C1.CS(=O)(O)=O, belongs to phthalazine compound. In a article, author is El-Adl, Khaled, introduce new discover of the category.

In accordance with the significant impetus of the discovery of potent vascular endothelial growth factor receptor 2 (VEGFR-2) inhibitors, herein, we report the design, synthesis, and anticancer evaluation of 12 new N-substituted-4-phenylphthalazin-1-amine derivatives against HepG2, HCT-116, and MCF-7 cells as VEGFR-2 inhibitors. The results of the cytotoxicity investigation indicated that HCT-116 and MCF-7 were the most sensitive cell lines to the influence of the newly synthesized derivatives. In particular, compound 7a was found to be the most potent derivative among all the tested compounds against the three cancer cell lines, HepG2, HCT116, and MCF-7, with IC50 = 13.67 +/- 1.2, 5.48 +/- 0.4, and 7.34 +/- 0.6 mu M, respectively, which is nearly equipotent to that of sorafenib (IC50 = 9.18 +/- 0.6, 5.47 +/- 0.3, and 7.26 +/- 0.3 mu M, respectively). All synthesized derivatives, 4a,b-8a-c, were evaluated for their inhibitory activities against VEGFR-2. The tested compounds displayed high to low inhibitory activity, with IC50 values ranging from 0.14 +/- 0.02 to 9.54 +/- 0.85 mu M. Among them, compound 7a was found to be the most potent derivative that inhibited VEGFR-2 at an IC50 value of 0.14 +/- 0.02 mu M, which is nearly 72% of that of the sorafenib IC50 value (0.10 +/- 0.02 mu M). Compounds 7b, 8c, 8b, and 8a exhibited very good activity with IC50 values of 0.18 +/- 0.02, 0.21 +/- 0.03, 0.24 +/- 0.02, and 0.35 +/- 0.04 mu M, respectively. Molecular modeling studies were carried out for all compounds against the VEGFR-2 active site. The data obtained from biological testing highly correlated with that obtained from molecular modeling studies. However, these modifications led to new phthalazine derivatives with higher VEGFR-2 inhibitory activities than vatalanib and which are nearly equipotent to sorafenib.

Electric Literature of 886-86-2, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 886-86-2.

In a document, author is Wei, Cheng-Xi, introduce the new discover.

In a previous research, we synthesized and evaluated the anticonvulsant activity of a series of 6-substituted-oxy-[1,2,4] triazolo[3,4-a] phthalazine compounds. Reference to other studies, we deduce that the compounds may be useful for regulating inotropic activity by effecting stroke volume, so in this study, we evaluated 20 compounds (15a-t) for their changed inotropic activity by measuring the left atrium stroke volume in heart preparations isolated from Wistar rats. Among the 20 compounds, 15j was the most potent with an increased stroke volume of 27.39 +/- 3.16 % at the concentration of 50 mu M, compound 15m was identified as the most potent with an decreased stroke volume of -95.59 +/- 0.50 % at the same concentration which is much more effective than referenced drug Nifedipine (-55.22 +/- 1.87% at the concentration of 1 mu M).

A SO3H-bearing carbonaceous solid catalyst has been synthesized through sulfonation followed by the hydrothermal carbonization method from renewable resource polyethylene glycol. The biodegradable catalyst was characterized by XRD, TEM, FT-IR, and energy dispersive X-ray. The surface area and pore diameter of the catalyst were determined by a nitrogen adsorption-desorption isotherm experiment. A highly efficient multicomponent heteroannulation protocol for the synthesis of a library of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives has been developed by applying the solid acid catalyst. This synthesis was established to follow the group-assistant-purification chemistry process avoiding traditional chromatography. The aqueous reaction medium, easy recovery of the catalyst, and high yield of the products make the protocol attractive, sustainable, and economic. This work may not only lead to environmentally benign systems, but also will provide a new aspect of organic chemistry in water.

In a article, author is Hiiuk, Volodymyr M., introduce new discover of the category.

Two new 2D spin-crossover (SCO) analogues of Hofmann clathrates of composition [Fe(phth)(2)M-II(CN)(4)] (where phth = phthalazine; M-II = Pd, Pt) have been synthesized and their structures and switchable behaviour have been characterized. Single-crystal X-ray analysis reveals that the Pt and Pd derivatives contain Fe-II centres equatorially surrounded by four equivalent mu(4)-[M-II(CN)(4)](2-) groups. Two crystallographically equivalent phthalazine (phth) ligands occupy the axial positions of each Fe-II site, completing its octahedral coordination environment. The stabilization of these structures is realized via supramolecular C-HM interactions and pi-pi stacking. Temperature-dependent magnetic susceptibility measurements showed that Pt (T-1/2 down arrow = 211 K and T-1/2 up arrow = 218 K) and Pd (T-1/2 down arrow = 202 K and T-1/2 up arrow = 207 K) derivatives display cooperative spin crossover with narrow thermal hysteresis loops. In addition, spin crossover in these complexes was characterized by optical measurements, differential scanning calorimetry, and IR and Raman spectroscopy. This research shows that the use of phthalazine leads to the production of new SCO systems with attractive transition characteristics and opens up new perspectives for the design of switchable complexes based on fused bicyclic azine ligands.
