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 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.

RAB1 5 is a lead antibacterial agent in which trimethoprim is linked to phthalazine moiety. Similarly, our strategy in this research depends on the interconnection between some sulfa drugs and certain phthalazin-1(2H)-one scaffolds in an attempt to enhance their antibacterial activity. This approach was achieved through the combination of 4-substituted phthalazin-1(2H)-ones 9a, b or 14a, b with sulfanilamide 1a, sulfathiazole 1b or sulfadiazine 1c through amide linkers 6a, b to produce the target compounds 10a-d and 15a-e, respectively. The antibacterial activity of the newly synthesized compounds showed that all tested compounds have antibacterial activity higher than that of their reference sulfa drugs 1a-c. Compound 10c represented the highest antibacterial activity against Gram-positive bacteria Streptococcus pneumonia and Staphylococcus aureus with MIC = 0.39 mu mol/mL. Moreover, compound 10d displayed excellent antibacterial activity against Gram-negative bacteria Escherichia coli and Salmonella Lyphimurium with MIC = 0.39 and 0.78 mu mol/mL, respectively.

HPLC of Formula: https://www.ambeed.com/products/622-95-7.html, Chemistry graduates have much scope to use their knowledge in a range of research sectors, including roles within chemical engineering, chemical and related industries, healthcare and more. 622-95-7, Name is 1-(Bromomethyl)-4-chlorobenzene, SMILES is ClC1=CC=C(CBr)C=C1, belongs to phthalazine compound. 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.
