The selectivity index of the anti-influenza action of {5-[(4,6-dimethylpyrimidin-2-yl)sulfanyl]-1H-tetrazol-1-yl}acetic acid, which had very low cytotoxicity, was twice as high as the selectivity index of the reference drug rimantadine.

Name: 2-Chloropyrimidine, 2-Chloropyrimidine is a monochlorinated pyrimidine with plant growth regulating activity. Chloropyrimidine is a useful reagent in the preparation of antivirals and other biologically active compounds.
2-Chloropyrimidine undergoes cobalt-catalyzed cross-coupling reaction with aryl halides.
2-Chloropyrimidine is a molecule that can be synthesized by the oxidation of pyrimidine with hydrogen peroxide and hydrochloric acid. The reaction proceeds through an electrochemical process in which the oxidation catalyst is a platinum electrode. This reaction is catalyzed by the nucleophilic attack of malonic acid on the chloropyrimidine at the methylene group. This efficient method for making 2-chloropyrimidine has been applied to synthesize aryl halides, including phenyl chloropyrimidine and pyridyl chloropyrimidine, from their corresponding chloride and bromide precursors. The fluorescence properties of 2-chloropyrimidine have been studied in coordination chemistry, where it forms complexes with metal ions such as Mn2+.

A. research published 《 Complexes of carboxymethylcellulose with Cu²⁺-ions as a prototype of antitumor agent》, the research content is summarized as follows. The search for new promising carries and vectors for the purposes of nuclear medicine with multifunctional effects is the most difficult problem in this branch of medicine. Among the components that are used to create carriers, one of the most perspective is the polysaccharide CM-cellulose (CMC). This choice is due to CMC high solubility in aqueous and saline solutions, low toxicity, high biocompatibility, as well as the content of a large number of anionic (carboxyl) and hydroxyl functional groups, which are capable of strong binding of polyvalent metal ions. In our work CMC were bound to Cu²⁺ ions that resulted in a collapse of the polymer macromol. and formation of the CMC- Cu²⁺ binary complexes. The binary complexes addnl. adsorbed 2-aminopyrimidine (AP) and formed the CMC- Cu²⁺-AP ternary complexes. The binary and ternary complexes were characterized by dynamic light scattering, laser electrophoresis, UV-spectrophotometry, TEM- microscopy, thin layer chromatog. and cell viability with the following main conclusions: (a) An increase in the copper content from up to 20 wt% leads to altering the size of CMC particles in water solution from 400 to 340 nm. Further binding of AP has no effect on the particle size. (b) In physiol. solution, the size of the ternary complex particles was addnl. decreased down to 200-220 nm. (c) The complex particles are stable against aggregation in water surrounding due to their total neg. charge. (d) Their cytotoxicity in relation to leukemic cells significantly exceeds that in relation to normal lymphocytes, creating an attractive therapeutic window. The results show good prospects for the CMC-copper complexes as drug carriers.

Olean-Oliveira, Andre;Monteiro Seraphim, Patricia;Teixeira, Marcos F. S. research published 《 Methylated DNA impedimetric immunosensor based on azo-polymer-AuNPs dots and 5-methylcytosine antibody using dissolved oxygen as a redox probe》, the research content is summarized as follows. The present work describes the development of an electrochem. immunosensor for the direct determination of methylated DNA using dissolved oxygen as the redox probe. The oxygen-sensitive response is possible due to the presence of a redox conducting polymer based on the Bismarck Brown Y dye (poly(azo-BBY)). In addition to the azo-polymer, gold nanoparticles (AuNPs) were formed in the polymer film by encapsulation to increase the active surface area and enhance sensor performance. The platform was easily synthesized using a single-step electropolymerization technique in a solution containing the BBY monomer and HAuCl4 salt. The immunosensor was developed by simply immobilizing the 5-methylcytosine antibody (Ab-5-mC) with high affinity to 5-mC on the surface of a device coated with azo-polymer-AuNPs dots. No secondary antibodies or enzymes were used in constructing this device. The immunosensor performance was evaluated by electrochem. impedance spectroscopy (EIS) in different concentrations of 5-methylcytosine (5-mC) in 0.10 mol L-1 phosphate buffer solution (PBS) solution containing atm. oxygen. A calibration curve was obtained by varying the resistance of the system as a function of the 5-mC concentration, revealing a limit of detection (LOD) in picograms per mL.

Ohtsu, Naoko;Ohgaki, Ryuichi;Jin, Chunhuan;Xu, Minhui;Okanishi, Hiroki;Takahashi, Ryo;Matsui, Akiko;Kishimoto, Wataru;Ishiguro, Naoki;Kanai, Yoshikatsu research published 《 Functional coupling of organic anion transporter OAT10 (SLC22A13) and monocarboxylate transporter MCT1 (SLC16A1) influencing the transport function of OAT10》, the research content is summarized as follows. OAT10 (SLC22A13) is a transporter highly expressed in renal tubules and transporting organic anions including nicotinate, β-hydroxybutyrate, ρ-aminohippurate, and orotate. In transport assays using Xenopus oocytes and HEK293 cells, we found that apparent substrate selectivity of OAT10 was different between the expression systems, particularly less pronounced uptake of β-hydroxybutyrate in HEK293 cells. Because functional coupling between transporters may interfere with functional properties of the transporter, we searched for endogenous transporters in HEK293 cells that could affect OAT10. By means of comprehensive approach with co-immunoprecipitation followed by LC-MS/MS anal., we identified monocarboxylate transporter MCT1 (SLC16A1) as phys. coupled with OAT10. The knockdown of MCT1 in OAT10-expressing HEK293 cells increased the uptake of β-hydroxybutyrate and nicotinate, common substrates of OAT10 and MCT1, whereas the uptake of orotate, a substrate of only OAT10, was not affected. MCT1 is supposed to act as an escape route and mediate the efflux of nicotinate and β-hydroxybutyrate taken up by OAT10 localized nearby MCT1, as suggested by co-immunoprecipitation This functional coupling would explain altered apparent substrate selectivity in HEK293 cells compared with Xenopus oocytes. The findings in this study warn in transporter studies that the expression system can interfere with assessing correct transport properties due to unexpected interactions with endogenous transporters.

Obot, I. B.;Bahraq, Ashraf A.;Alamri, Aeshah H. research published 《 Density functional theory and molecular dynamics simulation of the corrosive particle diffusion in pyrimidine and its derivatives films》, the research content is summarized as follows. The search and discovery of corrosion inhibitors to mitigate sweet corrosion in the oil and gas industry has been carried out mainly using tedious and costly exptl. approaches. In this study, theor. approach using d. functional theory (DFT) and mol. dynamics (MD) simulation were utilized to investigate the adsorption and diffusion properties of pyrimidine and six (6) of its derivatives on carbon steel corrosion in simulated CO₂-containing environment. The DFT calculations revealed that the electrons can easily flow from the HOMO orbitals of all the pyrimidine mols. to the empty substrate orbitals until reaching the equilibrium state as the values of EHOMO (-7.63 to -5.55 eV) are much higher than the Fermi level energy of Fe (-13.16 eV). Besides, the binding energy of mols. on the Fe (110) surface obtained using MD simulation was found to be in the range of 60.67 to 99.28 kcal/mol, indicating the pyrimidine mols. can strongly interact with the iron atoms of the metal surface. In the sweet medium, the diffusion coefficient (D) of HCO₃– was in the range of 0.81 to 1.41 m² s^-1, which is about three times less than the diffusion coefficient of HCO₃– in water. Self-diffusion coefficient (D’), and fractional free volume (FFV) were used to further investigate the diffusion mechanism of the pyrimidine mols. in CO₂ corrosive medium. Pyrimidine containing carboxylic acid and thioamide groups gave the best result as CO₂ corrosion inhibitor theor. The DFT and MD results provided useful insights and a theor. basis for the screening and design of new sweet corrosion inhibitors for carbon steel.

Angiogenesis, the active formation of new blood vessels from pre-existing ones, is a complex and demanding biol. process that plays an important role in physiol. as well as pathol. settings. Recent evidence supports cell metabolism as a critical regulator of angiogenesis. However, whether and how cell metabolism regulates endothelial growth factor receptor levels and nucleotide synthesis remains elusive. We here shown in both human cell lines and mouse models that during developmental and pathol. angiogenesis, endothelial cells (ECs) use glutaminolysis-derived glutamate to produce aspartate (Asp) via aspartate aminotransferase (AST/GOT). Asp leads to mTORC1 activation which, in turn, regulates endothelial translation machinery for VEGFR2 and FGFR1 synthesis. Asp-dependent mTORC1 pathway activation also regulates de novo pyrimidine synthesis in angiogenic ECs. These findings identify glutaminolysis-derived Asp as a regulator of mTORC1-dependent endothelial translation and pyrimidine synthesis. Our studies may help overcome anti-VEGF therapy resistance by targeting endothelial growth factor receptor translation.

Oba, Yasuhiro;Takano, Yoshinori;Furukawa, Yoshihiro;Koga, Toshiki;Glavin, Daniel P.;Dworkin, Jason P.;Naraoka, Hiroshi research published 《 Identifying the wide diversity of extraterrestrial purine and pyrimidine nucleobases in carbonaceous meteorites》, the research content is summarized as follows. The lack of pyrimidine diversity in meteorites remains a mystery since prebiotic chem. models and laboratory experiments have predicted that these compounds can also be produced from chem. precursors found in meteorites. Here we report the detection of nucleobases in three carbonaceous meteorites using state-of-the-art anal. techniques optimized for small-scale quantification of nucleobases down to the range of parts per trillion (ppt). In addition to previously detected purine nucleobases in meteorites such as guanine and adenine, we identify various pyrimidine nucleobases such as cytosine, uracil, and thymine, and their structural isomers such as isocytosine, imidazole-4-carboxylic acid, and 6-methyluracil, resp. Given the similarity in the mol. distribution of pyrimidines in meteorites and those in photon-processed interstellar ice analogs, some of these derivatives could have been generated by photochem. reactions prevailing in the interstellar medium and later incorporated into asteroids during solar system formation. This study demonstrates that a diversity of meteoritic nucleobases could serve as building blocks of DNA and RNA on the early Earth.

Nwachukwu, Chideraa I.;Patton, Leanna J.;Bowling, Nathan P.;Bosch, Eric research published 《 Ditopic halogen bonding with bipyrimidines and activated pyrimidines》, the research content is summarized as follows. The potential of pyrimidines to serve as ditopic halogen-bond acceptors is explored. The halogen-bonded cocrystals formed from solutions of either 5,5′-bipyrimidine (C₈H₆N₄) or 1,2-bis(pyrimidin-5-yl)ethyne (C₁₀H₆N₄) and 2 molar equivalents of 1,3-diiodotetrafluorobenzene (C₆F₄I₂) have a 1:1 composition Each pyrimidine moiety acts as a single halogen-bond acceptor and the bipyrimidines act as ditopic halogen-bond acceptors. In contrast, the activated pyrimidines 2- and 5-{[4-(dimethylamino)phenyl]ethynyl}pyrimidine (C₁₄H₁₃N₃) are ditopic halogen-bond acceptors, and 1:1 halogen-bonded cocrystals are formed from 1:1 mixtures of each of the activated pyrimidines and either 1,2- or 1,3-diiodotetrafluorobenzene. A 1:1 cocrystal was also formed between 2-{[4-(dimethylamino)phenyl]ethynyl}pyrimidine and 1,4-diiodotetrafluorobenzene, while a 2:1 cocrystal was formed between 5-{[4-(dimethylamino)phenyl]ethynyl}pyrimidine and 1,4-diiodotetrafluorobenzene.

4595-59-9, 5-Bromopyrimidine is a reactive intermediate that is used in the synthesis of 4-methoxyphenylboronic acid. 5-Bromopyrimidine has been shown to be nucleophilic, reacting with β-amino acids under basic conditions to form the corresponding 2-bromo amide. It also undergoes cross-coupling reactions with halides and can be used as a building block for other organic compounds. 5-Bromopyrimidine has optical properties that are characteristic of aromatic molecules, including strong absorption bands in the ultraviolet region and visible light region.
5-Bromopyrimidine undergoes direct metallation with lithuium diisopropylamide to yield 4-lithio-5-bromopyrimidine., Application In Synthesis of 4595-59-9
