Synthesis of acylguanidine analogues: inhibitors of ADP-induced platelet aggregation

Routine screening of compounds for inhibition of ADP-induced platelet aggregation in vitro revealed that 1′-hexamethylenebis[3-cyclohexyl-3-[(cyclohexylimino)(4-morpholinyl)methyl] urea] was active and represented the first example of a bis(acylguanidine) with possible antithrombotic activity. In order to develop a structure-activity relationship for this class of compounds, we synthesized a number of new bis(acylguanidines). These were tested in vitro, and several analogues were also active. Ex vivo testing revealed that compounds 22, 41, 58, and 70-73 were orally active in rats or guinea pigs.

Positively charged conjugated microporous polymers with antibiofouling activity for ultrafast and highly selective uranium extraction from seawater

Uranium high-efficiency separation from seawater still has some obstacles such as slow sorption rate, poor selectivity and biofouling. Herein, we report a strategy for ultrafast and highly selective uranium extraction from seawater by positively charged conjugated microporous polymers (CMPs). The polymers are synthesized by Sonogashira-Hagihara cross-coupling reaction of 1,3-dibromo-5,5-dimethylhydantoin and 1,3,5-triethynylbenzene, and then modified with oxime and carboxyl via click reaction. The CMPs show an ultrafast sorption (0.46 mg g?1 day?1) for uranium, and possess an outstanding selectivity with a high sorption capacity ratio of U/V (8.4) in real seawater. The study of adsorption process and mechanism indicate that the CMPs skeleton exhibits high affinity for uranium and can accelerate the sorption, and uranium(VI) is adsorbed on the materials by the interaction of oxime/carboxyl ligands and hydantoin. Moreover, the material can be simply loaded onto the filter membrane, and shows remarkable antibiofouling properties against E. coli and S. aureus and excellent uptake capacity for uranium with low concentration in real seawater. This work may provide a promising approach to design adsorbents with fast adsorption rate, high selectivity and antibacterial activity, and expand the thinking over the development of novel and highly efficient adsorbents for uranium extraction from seawater.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 461-72-3, and how the biochemistry of the body works.Application of 461-72-3

Investigation of a family of structurally-related guanidinium ionic liquids through XPS and thermal analysis

A family of structurally-related guanidinium bistriflimide ionic liquids has been prepared and characterized. TGA analyses showed a high thermal stability for all the proposed ionic liquids while DSC and XPS analyses divided them into distinct subsets depending on whether one or more constraining cycles were present. The results obtained highlighted the influence of the cation structure on some of the physico-chemical properties and thus the possibility to tune them by selecting proper substituents. The solvatochromic parameters of a selected guanidinium IL have also been studied.

Electrochemical characterization of phenytoin and its derivatives on bare gold electrode

Phenytoin (5,5-diphenylhydantoin), one of the most frequently used anticonvulsant and antiarrhythmic drugs, was examined and determined at bare gold electrode in 0.05 M NaHCO3 using its anodic activity by cyclic voltammetry (CV) and square wave voltammetry (SWV). Gold electrode is highly sensitive to the phenytoin concentration (the investigated level of concentrations is usually found in human serum of patients treated with phenytoin), providing linear relationships for a set of lower concentrations (0.5, 0.6, 0.8, 1.0 mumol dm-3) and for a set of higher concentrations (10, 20, 30, 40, 50 mumol dm-3). The effects of the substituent on the phenyl rings on the electrochemical behavior of two derivatives, 5,5-di(4-chlorophenyl) hydantoin and 5,5-di(4-methylphenyl) hydantoin, were examined by CV. A computational study in correlation with the experimental voltammetric results enabled to propose the oxidation mechanisms: the investigated compounds undergo oxidation involving transfer of 1e- and 1 proton by irreversible, diffusion controlled process.

Magnesium based coordination polymers: Syntheses, structures, properties and applications

Coordination polymers (CPs) and/or metal?organic frameworks (MOFs) have been a hot research topic over the past two decades. Many CPs structures based on p-, d-, f- and some s-block metal ions, including magnesium (Mg), have been reported. While not as common in the literature as some other metals, magnesium-based CPs have unique potential applications, largely because of the specific properties of the Mg metal. Mg-CPs can possess high gravimetric gas storage capacities due to the metal’s low density, can facilitate base-catalyzed reactions as a result of its strong Lewis acidity, and have shown high performance as electrode materials due to its high-density energy storage capacity. This review intends to provide an overview on the research related to Mg-CPs in the past twenty years. We will briefly describe various structural features, important properties, and potential applications of the Mg-CPs reported during this time period. A number of representative examples will be discussed for each type of important application.

Phase Transition Enthalpy Measurements of Organic and Organometallic Compounds. Sublimation, Vaporization and Fusion Enthalpies From 1880 to 2015. Part 1. C1-C10

A compendium of phase change enthalpies published in 2010 is updated to include the period 1880-2015. Phase change enthalpies including fusion, vaporization, and sublimation enthalpies are included for organic, organometallic, and a few inorganic compounds. Part 1 of this compendium includes organic compounds from C1-C10. Part 2 of this compendium, to be published separately, will include organic and organometallic compounds from C11 to C192. Sufficient data are presently available to permit thermodynamic cycles to be constructed as an independent means of evaluating the reliability of the data. Temperature adjustments of phase change enthalpies from the temperature of measurement to the standard reference temperature, T = 298.15 K, and a protocol for doing so are briefly discussed.
