The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: cis-Dichlorobis(pyridine)platinum(II)( cas:15227-42-6 ) is researched.Safety of cis-Dichlorobis(pyridine)platinum(II).Ghezzi, AnnaRita; Aceto, Maurizio; Cassino, Claudio; Gabano, Elisabetta; Osella, Domenico published the article 《Uptake of antitumor platinum(II) complexes by cancer cells, assayed by inductively coupled plasma mass spectrometry (ICP-MS)》 about this compound( cas:15227-42-6 ) in Journal of Inorganic Biochemistry. Keywords: uptake antitumor platinum complex lipophilicity MCF7 cell. Let’s learn more about this compound (cas:15227-42-6).

A systematic study on intracellular Pt uptake and Pt accumulation ratio in breast cancer MCF-7 cell line has been performed on a number of Pt(II)-complexes, namely cisplatin, carboplatin and oxaliplatin, clin. employed as antitumor drugs, trans- and cis-[Pt(Cl)2(pyridine)2] and cis-[Pt(Cl)2(pyridine)(5-SO3H-isoquinoline)] complexes, previously investigated also as potential telomerase inhibitors. In particular, long incubation times have been chosen in order to understand the fate of the complexes in the cells. For this purpose, sub-acute drug concentrations must be employed and, therefore, a very sensitive method of anal. like as inductively coupled plasma mass spectrometry (ICP-MS) superior to the widely employed at. absorption spectroscopy (AAS) has been adopted. Any relationships among uptake/accumulation and several parameters such as drug structure, lipophilicity, drug concentration and incubation time have been sought and analyzed: the bulk of data point for a passive diffusion mechanism through the cell membrane.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Buzzacchera, Irene; Xiao, Qi; Han, Hong; Rahimi, Khosrow; Li, Shangda; Kostina, Nina Yu.; Toebes, B. Jelle; Wilner, Samantha E.; Moller, Martin; Rodriguez-Emmenegger, Cesar; Baumgart, Tobias; Wilson, Daniela A.; Wilson, Christopher J.; Klein, Michael L.; Percec, Virgil researched the compound: 1-Bromoundecane( cas:693-67-4 ).Reference of 1-Bromoundecane.They published the article 《Screening Libraries of Amphiphilic Janus Dendrimers Based on Natural Phenolic Acids to Discover Monodisperse Unilamellar Dendrimersomes》 about this compound( cas:693-67-4 ) in Biomacromolecules. Keywords: dendrimer dendrimersome. We’ll tell you more about this compound (cas:693-67-4).

Natural, including plant, and synthetic phenolic acids are employed as building blocks for the synthesis of constitutional isomeric libraries of self-assembling dendrons and dendrimers that are the simplest examples of programmed synthetic macromols. Amphiphilic Janus dendrimers are synthesized from a diversity of building blocks including natural phenolic acids. They self-assemble in water or buffer into vesicular dendrimersomes employed as biol. membrane mimics, hybrid and synthetic cells. These dendrimersomes are predominantly uni- or multilamellar vesicles with size and polydispersity that is predicted by their primary structure. However, in numerous cases, unilamellar dendrimersomes completely free of multilamellar assemblies are desirable. Here, we report the synthesis and structural anal. of a library containing 13 amphiphilic Janus dendrimers containing linear and branched alkyl chains on their hydrophobic part. They were prepared by an optimized iterative modular synthesis starting from natural phenolic acids. Monodisperse dendrimersomes were prepared by injection and giant polydisperse by hydration. Both were structurally characterized to select the mol. design principles that provide unilamellar dendrimersomes in higher yields and shorter reaction times than under previously used reaction conditions. These dendrimersomes are expected to provide important tools for synthetic cell biol., encapsulation, and delivery.

Author is Moggi, Luca; Varani, Graziano; Sabbatini, Nanda; Balzani, Vincenzo.

The photochem. behavior of cis- and trans-Pt(py)2Cl2 in CHCl3 solutions has been investigated using 313 nm light. The cis isomer undergoes 2 simultaneous photoreactions, one being an intramol. photoisomerization process (Φisom ∼0.04) and the other a photodissociation reaction involving the pyridine ligand (Φdiss ∼ 0.025). This latter photoreaction provides an intermol. path for the cis → trans isomerization since its products (namely, free pyridine and Pt-containing species) recombine thermally to give cis- and trans-Pt(py)2Cl2 in a 2:1 ratio. The trans isomer undergoes photoisomerization and pyridine release but with much lower quantum yields (∼0.001). Qual. results concerning the photochem. behavior of the above complexes in MeOH solutions upon 254 or 313 nm irradiation are also reported.

Among pyridine vibrations the ν4, ν9, ν10 and ν27, ring deformation vibrations, and the ν16, H in-plane deformation vibration, shift significantly to a higher frequency by complex formation. Among the rest, the ν10, in-plane ring deformation vibration, is the most sensitive upon complex formation.

Compound: Picolinamide, is researched, Molecular C6H6N2O, CAS is 1452-77-3, about Magnetically enhanced polymersupported ceria nanocatalysts for the hydration of nitriles.

The heterogeneous catalysis of the hydration of nitriles to amides is a process of great industrial relevance in which cerium(IV) oxide (also referred to as ceria) has shown an outstanding catalytic performance. The use of non-supported ceria nanoparticles is related to difficulties in the purification of the product and the recovery and recyclability of the catalyst. Therefore, in this work, ceria nanoparticles are supported on a polymer matrix either by synthesizing polymer particles by so-called Pickering miniemulsions while using ceria nanoparticles as emulsion stabilizers or, as a comparison, by in-situ crystallization on preformed polymer particles. The former strategy presents significant advantages over the latter in terms of time and consumption of resources, and it facilitates an easier scale-up of the process. In both strategies, the incorporation of a magnetoresponsive core within the polymer matrix allows the recovery and the recycling of the catalyst by simple application of a magnetic field and offers an enhancement of the catalytic efficiency.

The present work is aimed to produce di-Me carbonate by coupling of CH3OH and CO2 with 2-cyanopyridine over ZnO-CeO2 catalysts prepared by co-precipitation method. These catalysts were characterized by XRD, TEM, UV-Vis DRS, BET surface area, CO2 and NH3-TPD techniques and applied for the titled reaction. Among the investigated catalysts 10ZnO-90CeO2 catalyst with CeO2 crystallite size 8.0 nm exhibited 96% conversion of methanol with 99% selectivity to di-Me carbonate. The superior catalytic activity is a unified effect of crystalline size of CeO2 and presence of an optimum number of acidic and basic sites. This protocol offers enhanced conversion of methanol with the simultaneous conversion of 2-cyanopyridine into 2-picolinamide by removing water mols. formed in the reaction.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called The Guanidine-Promoted Direct Synthesis of Open-Chained Carbonates, published in 2019, which mentions a compound: 693-67-4, mainly applied to linear carbonate preparation green chem; carbon dioxide alc alkyl bromide nucleophilic substitution tetramethylguanidine catalyst, Name: 1-Bromoundecane.

In order to reduce CO2 accumulation in the atm., chem. fixation methodologies were developed and proved to be promising. In general, CO2 was turned into cyclic carbonates by cycloaddition with epoxides. However, the cyclic carbonates need to be converted into open-chained carbonates by transesterification for industrial usage, which results in wasted energy and materials. Herein, a process catalyzed by tetramethylguanidine (TMG) to afford linear carbonates directly is reported. This process is greener and shows potential for industrial applications.
