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).

Chemistry involves the study of all things chemical �chemical processes, chemical compositions and chemical manipulation �in order to better understand the way in which materials are structured, how they change and how they react in certain situations. , Name: 4-Cyano-4-((phenylcarbonothioyl)thio)pentanoic acid, 201611-92-9, Name is 4-Cyano-4-((phenylcarbonothioyl)thio)pentanoic acid, molecular formula is C13H13NO2S2, belongs to phthalazine compound. In a document, author is Zinczenko, Wiktoria, introduce the new discover.

Triazolo[3,4-a]phthalazine as well as their chloro and nitro derivatives were subjected to the reactions with the carbanions typical for the vicarious nucleophilic substitution (VNS) of hydrogen. The reactions were strongly dependent on the substituents present on the triazolo[3,4-a]phthalazine ring and resulted not only in the substitution of hydrogen but also in exchange of chlorine atom and pyridazine ring scission; the latter process dominated for the unsubstituted triazolophthalazine. Two of the products showed promising stimulating activity towards the central nervous system with no significant toxic effects.

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 54381-16-7, in my other articles.

Piperazine rings are important heterocyclic targets in organic synthesis and are useful synthetic intermediates or intricate parts of biologically active molecules. In our efforts, a series of piperazine derivatives has been prepared discovering new classes of antimicrobial agents, including bis(phthalimido)piperazine, bis(3-aminopropyl) piperazine, 2,3-dihydro-phthalazine-1,4-dione, and bis(3,4-aminophenol)piperazine. The synthesized antimicrobial agents have been studied using various spectroscopic techniques. Furthermore, these compounds have been screened for their in vitro antimicrobial activity against selected bacterial and fungal strains. Three compounds exhibited mild to good antibacterial activity, but somewhat lower antifungal activity against tested microbial strains.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 7524-50-7 is helpful to your research. Category: phthalazines.

NO2 derivative of title compound was synthesized and the nature of its intramolecular hydrogen bond (HB) was investigated. Furthermore, the topological properties of the electron density distributions for N-H…O intramolecular bridges were analyzed in terms of the Bader theory of atoms in molecules (AIM). The electron density (?) and Laplacian (?2?) properties, estimated by AIM calculations, indicated that O…H bond possesses low ? and positive ?2? values which are in agreement with electrostatic character of the HBs, whereas N-H bonds have covalent character (?2?<0). Moreover, steric effect of the t-Bu group on structure and topological parameters of pyrazolo[1,2-b]phthalazine conformers was studied.
