Author is Griffith, Darren; Bergamo, Alberta; Pin, Sara; Vadori, Marta; Mueller-Bunz, Helge; Sava, Gianni; Marmion, Celine J..

We describe the synthesis and characterization of a novel class of PtII and PtIV pyridine-hydroxamic acid (pyhaH) complexes of general formula cis-[PtIICl2(x-pyhaH)2] and cis-[PtIVCl4(x-pyhaH)2], resp., (where x = 3 or 4) in which the pyridine-hydroxamic acid is coordinated to the platinum ion via the pyridine nitrogen only leaving the hydroxamic acid free to potentially release cytotoxic nitric oxide (NO). The crystal structure of the PtIV derivative, cis-[PtCl4(4-pyhaH)2]·2CH3OH is reported. To establish the biol. effect of the uncoordinated hydroxamic acid moiety in the PtII compounds, the corresponding pyridinecarboxylic acid (pycaH) complexes of general formula cis-[PtIICl2(x-pycaH)2] (where x = 3 or 4) and the PtII pyridine (py) complex cis-[PtIICl2(py)2] were synthesized and served as reference standards The NO-releasing properties of each of the PtII compounds, the pyhaH and the pycaH ligands were studied. The PtII pyridine-hydroxamic acid derivatives were found to induce potent in vitro effects attributable to either NO-release from the hydroxamic acid moiety and/or stimulation of inducible nitric oxide synthase of endothelial cells.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 693-67-4, is researched, Molecular C11H23Br, about Developing design tools for introducing and tuning structural order in ionic liquids, the main research direction is dodecyl methyl alkylimidazolium bromide preparation thermal crystal structure mol.Recommanded Product: 693-67-4.

To investigate what is driving structural order in imidazolium-based ionic liquids (ILs) a series of asym. 1-dodecyl-2-methyl-3-alkylimidazolium bromides I [R = H, Me, n-Bu, etc.] was synthesized, fully characterized and their structures and properties compared with the analogous 1-dodecyl-3-alkylimidazolium as well as the 1,2,3-triazolium bromides. The aim was to examine the influence of the replacement of the most acidic 2-H proton on the imidazolium head group by methylation on the properties and structure of ILs. For all compounds, except for compounds with butyl- and hexyl-chains as well as the protonated species, mesophase formation was observed Obviously, the simple presence of long alkyl chains such as dodecyl (a design concept frequently put forward in the literature) was not sufficient to support mesophase formation alone. Rather, for the formation of a liquid crystalline phase, a balance between attractive van der Waals forces, hydrogen bonds, and electrostatic interactions was required. Data from temperature-dependent small-angle X-ray scattering (SAXS) and polarizing optical microscopy (POM) suggested three different cation conformations for the studied compounds I: cations with 0 ≤ n ≤ 4 exhibited a near-linear conformation; for 5 ≤ n ≤ 10 a V-shape is adopted, and for n = 11 or 12 a U-shape was found. It was demonstrated that the structural possibility for an interdigitation of the long chains is an influential factor for the formation of a mesophase.

Formula: C14H9Cl. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 4-Chloro-4′-ethynyl-1,1′-biphenyl, is researched, Molecular C14H9Cl, CAS is 57399-11-8, about Copper-Catalyzed and Proton-Directed Selective Hydroxymethylation of Alkynes with CO2. Author is Wang, Mei-Yan; Jin, Xin; Wang, Xiaofei; Xia, Shumei; Wang, Yue; Huang, Shouying; Li, Ying; He, Liang-Nian; Ma, Xinbin.

An intriguing strategy for copper-catalyzed hydroxymethylation of alkynes with CO2 and hydrosilane was developed. Switched on/off a proton source, for example, t-BuOH, direct hydroxymethylation and reductive hydroxymethylation could be triggered selectively, delivering a series of allylic alcs. and homobenzylic alcs., resp., with high levels of Z/E, regio- and enantioselectivity. Such a selective synthesis is attributed to the differences in response of vinylcopper intermediate to proton and CO2. The protonation of vinylcopper species is demonstrated to be prior to hydroxymethylation, thus allowing a diversion from direct alkyne hydroxymethylation to reductive hydroxymethylation in the presence of a suitable proton source.

Efficient viral or nonviral delivery of nucleic acids is the key step of genetic nanomedicine. Both viral and synthetic vectors have been successfully employed for genetic delivery with recent examples being DNA, adenoviral, and mRNA-based Covid-19 vaccines. Viral vectors can be target specific and very efficient but can also mediate severe immune response, cell toxicity, and mutations. Four-component lipid nanoparticles (LNPs) containing ionizable lipids, phospholipids, cholesterol for mech. properties, and PEG-conjugated lipid for stability represent the current leading nonviral vectors for mRNA. However, the segregation of the neutral ionizable lipid as droplets in the core of the LNP, the “”PEG dilemma””, and the stability at only very low temperatures limit their efficiency. Here, we report the development of a one-component multifunctional ionizable amphiphilic Janus dendrimer (IAJD) delivery system for mRNA that exhibits high activity at a low concentration of ionizable amines organized in a sequence-defined arrangement. Six libraries containing 54 sequence-defined IAJDs were synthesized by an accelerated modular-orthogonal methodol. and coassembled with mRNA into dendrimersome nanoparticles (DNPs) by a simple injection method rather than by the complex microfluidic technol. often used for LNPs. Forty four (81%) showed activity in vitro and 31 (57%) in vivo. Some, exhibiting organ specificity, are stable at 5°C and demonstrated higher transfection efficiency than pos. control experiments in vitro and in vivo. Aside from practical applications, this proof of concept will help elucidate the mechanisms of packaging and release of mRNA from DNPs as a function of ionizable amine concentration, their sequence, and constitutional isomerism of IAJDs.

The article 《Design of organoruthenium complexes for nanoparticle functionalization》 in relation to this compound, is published in Journal of Organometallic Chemistry. Let’s take a look at the latest research on this compound (cas:1452-77-3).

In recent years, extensive research efforts have been focused on loading metal complexes onto macromol. systems such as nanoparticles. We report a ligand with a catechol group based on a picolinamide which allows for coordination to organoruthenium moieties while the catechol group remains available for loading on nanoparticles as delivery vehicles towards tumors. All the compounds were characterized with standard anal. methods and the mol. structure of the ligand 1, and its Ru complexes 1a and 1b were determined by X-ray diffraction anal. The crystal structure of 1a and 1b showed pseudo-tetrahedral geometry of the Ru center with “”piano-stool”” conformation and 1 coordinated as an N,O-bidentate ligand, however, the latter depending on the reaction conditions employed. The Ru complexes 1a-1c were effectively loaded on magnetite nanoparticles as characterized by inductively-coupled plasma mass spectrometry (ICP-MS), transmission electron microscopy (TEM) and Fourier transform IR spectroscopy (FTIR).

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of CO2 Utilization called Evaluating the direct CO2 to diethyl carbonate (DEC) process: Rigorous simulation, techno-economical and environmental evaluation, Author is Yu, Bor-Yih; Wu, Pei-Jhen; Tsai, Chang-Che; Lin, Shiang-Tai, which mentions a compound: 1452-77-3, SMILESS is O=C(N)C1=NC=CC=C1, Molecular C6H6N2O, Quality Control of Picolinamide.

In this work, the plant-wide process to produce di-Et carbonate (DEC) from the direct reaction of CO2 with ethanol, which uses 2-cyanopyridine (2-CP) as an in situ dehydrating agent, is proposed for the first time. Rigorous design, optimization, ability in carbon reduction, techno-economic and feasibility analyses are all performed in this work. The process consists of two sections. The first one is the main section, in which DEC is generated, along with the removal of water using 2-CP to form 2-picolinamide (2-PA). The second one is the regeneration section, where 2-CP is converted back from 2-PA and recycled. Using simulated annealing method, the optimized CO2 reduction rate in the main section is 0.237 (Ton CO2/Ton DEC generated) on an annual basis. We identify that when the regeneration section is operated with a molar ratio of mesitylene to 2-PA being less than 2.05, the overall process can be in net CO2 reduction Under the constraint of 90 % regeneration of 2-CP as reported in available literature, the produced DEC can match the current market price range under 15 % internal rate of return (IRR), if 2-CP can be obtained with a price lower than 2.56 USD/kg (corresponding to DEC price of 1.10 USD/kg and ethanol price of 0.37 USD/kg) to 6.09 USD/kg (corresponding to DEC price of 1.90 USD/kg and ethanol price of 0.56 USD/kg).
