Unique Deuterium Exchange Reaction in Certain Substituted Ferrocenes

Deuterium exchange of certain substituted ferrocenes (under very mild basic conditions) occurs in only the substituted cyclopentadienyl-ring in non-statistical pattern; a ?->? (eta5->eta1) rearrangement mechanism is proposed to account for the novel pattern of exchange.

Addressing the Metabolic Stability of Antituberculars through Machine Learning

We present the first prospective application of our mouse liver microsomal (MLM) stability Bayesian model. CD117, an antitubercular thienopyrimidine tool compound that suffers from metabolic instability (MLM t1/2 < 1 min), was utilized to assess the predictive power of our new MLM stability model. The S-substituent was removed, a set of commercial reagents was utilized to construct a virtual library of 411 analogues, and our MLM stability model was applied to prioritize 13 analogues for synthesis and biological profiling. In MLM stability assays, all 13 analogues had superior metabolic stability to the parent compound, and six new analogues had acceptable MLM t1/2 values greater than or equal to 60 min. It is noteworthy that whole-cell efficacy and lack of relative mammalian cell cytotoxicity could not be predicted simultaneously. These results support the utility of our new MLM stability model in chemical tool and drug discovery optimization efforts. Addressing the Metabolic Stability of Antituberculars through Machine Learning We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 3094-87-9, and how the biochemistry of the body works.HPLC of Formula: C4H6FeO4

A NOVEL METHOD for STUDYING the CORROSION RESISTANCE and MICROSTRUCTURE of ENAMEL COATING MODIFIED on HIGH-STRENGTH STEEL in 3.5 wt.% NaCl SOLUTION

A new method was introduced to research the corrosion resistance of enamel coatings which were sintered at different temperatures in this paper.1-4 Scanning electrochemical microscopy (SECM) conjunction with capacitance-potential test and Mott-Schottky analysis technique were used to study the coating failure process and semiconductor conduction behavior of enamel coating in 3.5wt.% NaCl solution. The high strength steel (SAPH440) was selected as the metal substrate. The coatings which were sintered at different temperatures on the high strength steel were analyzed and their corrosion behaviors and microstructures were also measured by potentiodynamic polarization curves, Mott-Schottky analysis technique and scanning electrochemical microscopy.5-10 In this paper, five kinds of enamel coatings were prepared on high strength steel. The SECM results show that the Faraday current of the microprobe tip gradually decreases with the soaking time increasing, which indicates that the coatings become failure slowly with the invasion of water and aggressive ions. At the same time, the tip current was homogeneous during the immersion process, which reflected that the surface of the sample remained stable, no obvious bulges appeared. Capacitance-potential test and Mott-Schottky analysis7,8 show that the external ions and water molecules gradually penetrate into the coating; coating showed characteristics of n-type semiconductor as time increases, the capacitance increases gradually, the space charge layer thickness decreases, slope of Mott-Schottky curve decreased gradually which indicates that the failure of coating in the process of soaking slowly with the charge carrier density increases.

Structural characterization and electrochemical behavior of titanium carbon thin films

In the present work we report the results concerning the synthesis of Ti-C films obtained by a co-sputtering process of both titanium and graphite targets. The titanium content within the coatings has been adjusted in a wide range, allowing different structures of the films, to be formed. The chemical composition of the films was determined by X-ray photoelectron spectroscopy (XPS). Phase structure was analyzed by grazing angle X-ray diffraction (GXRD), while the morphology and microstructure were investigated by scanning electron microscopy (SEM). The possibility of using the resulting materials for electrochemical applications was also examined. For these purposes, the Ti-C films used as electrodes were investigated in terms of both reactivity and stability. Electrochemical investigations were carried out by using cyclic voltammetry and spectroscopy electrochemical techniques.

Metabolic and enzymatic activities of individual cells, spheroids and embryos as a function of the sample size

Respiration, photosynthesis and peroxidase activities of living spherical samples, such as algal protoplasts, breast cancer spheroids and bovine embryos, were characterized with scanning electrochemical microscopy (SECM). The concentration profile of the metabolic product around the spherical sample was directly measured by scanning with a probe microelectrode. According to the spherical diffusion theory, the total mass transfer rate per spherical sample is linear to the multiplication of the sample radius and the concentration difference between the sample surface and the bulk of the solution. Therefore, the sample radius is a key parameter to assess the viability of the living samples. For example, we investigated the respiration and photosynthesis activities as a function of the size of the protoplast (Bryopsis plumosa). The respiration rate was linear to the cube of the sample radius. On the contrary, the photosynthesis rate was linear to the square of the sample radius, suggesting that the former is controlled by the volume of the protoplast, and the latter is controlled by the surface area of the protoplast. We will also discuss the size-dependent activity of the breast cancer spheroids and the bovine embryos. Furthermore, relations between the sample size, the concentration difference, and the oxygen consumption rate of the cryo-preserved bovine blastocysts were investigated.

New examples of template catalysis based processes: Glycerol-like units as efficient promoters for dehydrative nucleophilic substitutions of ferrocenylmethanol

The direct high-yield synthesis without solvent and catalyst, under mild conditions, of eleven novel mono substituted ferrocenylmethyl ethers and amine derivatives from ferrocenemethanol and vicinal oxygenated alcohols and amines is here reported. The peculiar ability of these classes of non acidic compounds to favor the dehydrative nucleophilic substitution is attributed to the presence of vicinal oxygen atoms to the reactive group able to build a hydrogen bonding network with the reactant. The role of carbon dioxide and hexafluoroisopropanol was investigated to support the hypothesis that a template catalysis effect is occurring. The in vitro anti-fungal activity of some of these derivatives was tested on two plant fungi, Botrytis cinerea and Penicillium species, with moderate activity.

Ferrocenyl bisoxazoline as an efficient non-phosphorus ligand for palladium-catalyzed copper-free Sonogashira reaction in aqueous solution

Pd(OAc)2-catalyzed Sonogashira coupling reactions of alkynes and a variety of aryl halides with 1,3-bis(5-ferrocenylisoxazoline-3-yl)benzene as an efficient non-phosphorus ligand under copper-free conditions are presented. The main advantages over previous methodologies include low catalyst loading (0.2 mol% Pd(OAc)2 and 0.4 mol% ferrocenyl bisoxazoline ligand are sufficient for these coupling reactions), less problematic reaction medium (water?dimethylformamide) and more convenient operation (no requirement for nitrogen protection).
