Abstract:
Triazolopyridine-pyridine amine ligands are easily obtained by means of either thermal- or copper(II)-mediated reactions. Starting from a readily accessible iodo derivative of triazolopyridine-pyridine and different amines, this new family of compounds combines aromatic and aliphatic nitrogen atoms with promising coordinating properties. Furthermore, chemical derivatization of a new triazolopyridine-pyridine diamine compound, N1-[6-([1,2,3]triazolo[1,5-a]pyridin-3-yl)pyridin-2-yl]ethan-1,2-diamine, allows the preparation of several remote-pyridine-containing ligands.

Reactions of 2-(hydroxymethyl)pyridine (Hhmp) with PbCl2and Pb(NO3)2at room temperature led to the formation of two novel compounds, namely tetrakis[μ3-(pyridin-2-yl)methanolato]-tetrahedro-tetrakis[chloridolead(II)], [Pb4(C6H6NO)4Cl4], (I), and poly[(μ2-nitrato)[μ2-(pyridin-2-yl)methanolato]lead(II)], [Pb(C6H6NO)(NO3)]n, (II). Compound (I) exhibits a tetranuclear Pb4O4cubane structure, which is connected through π–π stacking interactions between the pyridine groups of the (pyridin-2-yl)methanolate (hmp−) ligands and through C—H...Cl interactions to form an interesting threefold diamondoid net

Abstract:
Abstract Most of the carbon dioxide (CO2) corrosion inhibition work published has been based on constituents that behave as surfactants (e.g., quaternary amines and imidazolines). For these compounds, a relationship has been found between the concentration for maximum efficiency and the critical micelle concentration (CMC) and, more recently, with the concentration of maximum adsorption (CMA) on platinum. This paper shows how the methodology developed to characterize inhibitors based on their CMA values is still applicable to non-surfactant corrosion inhibitors, which would not show a CMC. The

Abstract:
Abstract In sweet corrosion, corrosion scales such as iron carbonate are formed on the internal surfaces of oil and gas production and transport systems. Depending on the type of corrosion inhibition program and the age of production system before chemical treatment is implemented, the presence of corrosion scale could affect the performance of the inhibitor. Previous work completed by the authors' company investigated the interaction of iron carbonate and three inhibitor actives - quaternary amine, imidazoline, and phosphate ester. This study is a continuation and examines two more generic co

Abstract The condensate involving HS-, CO32−, Cl− and NH4+ usually causes severe corrosion of 20 steel in condensate stripping process of industrial coal gasification unit. The corrosion can easily lead to failure of pipe fittings and vessels, and result in economic losses and personal injury. To protect industrial coal gasification unit against corrosion, five inhibitors including imidazoline, imidazoline amide, mannich base quaternary ammonium salt, pyridine, and sodium molybdate are investigated with experiment of linear polarization curve, polarization curve, electrochemical impedance spec

The bibliographic study of chalcones of the type 1,3-aryl(heteryl)propen-2-one with thiosemicarbazidic 4- and 1,4-disubstituted and thisemicarbazonic groups respectively gives us the information that they have a wide spectrum of biological activity, but methods of their synthesis are less described in the literature, and they became our object of study. 4,5-Dihydro-1-H-(pyrazol-3-yl)phenylhydrazinecarbothioamides 3a and 3b were obtained according to the following scheme:Reagents and reaction conditions: i, ii) 2-Py, 25oC – 24h, 90-95oC – 3h, 77-82%; iii) DMF, CH3COOH, 70-80oC, 2-3h, 60-63%.

Hantzsch dihydropyridines represent an important source of hydrogen to be transfered to other un-saturated organic molecules, leading the formation of pyridine aromatic ring as driving force. The hydrogen transfer process was evaluated using 1,4-dyhydropyridines and heterogeneous cobalt cat-alyst supported over N-doped activated carbon. The 4-position of the dihydropyridine ring was sub-stituted with H (4a), Me (4b) and Ph (4c) groups, showing that only 1 reacted to yield the correspond-ing pyridine compound indicating that the presence of steric hindrance took place on the reaction.

Abstract:
Prostate cancer (PCa) is the second most frequently diagnosed malignancy, as well as a leading cause of cancer-related mortality in men globally. Despite the initial response to hormonal targeted therapy, the majority of patients ultimately progress to a lethal form of the disease, castration-resistant prostate cancer (CRPC). Therefore, the objective of this study was to discover and develop novel treatment modalities for CRPC. Chalcones are among the highly attractive scaffolds being investigated for their antitumor activities. A library of 26 chalcone analogs were designed, synthesized and e

It is known that pyridine derivatives possess significant biological activity, and that vanillin is a natural aromatic compound with pharmacoecological properties. Earlier research indicated that among the series of synthesized vanillin-based pyrido-dipyrimidine compounds, two of them show significant antioxidative activity. Based on the thermodynamic parameters obtained using the DFT method, the operative mechanism of the reaction of the investigated antioxidants with the DPPH radical was considered. Calculations are done in water, methanol, and benzene, to imitate real experimental condition
