Host cell glutamine metabolism as a potential antiviral target

A virus minimally contains a nucleic acid genome packaged by a protein coat. The genome and capsid together are known as the nucleocapsid, which has an envelope containing a lipid bilayer (mainly phospholipids) originating from host cell membranes. The viral envelope has transmembrane proteins that are usually glycoproteins. The proteins in the envelope bind to host cell receptors, promoting membrane fusion and viral entry into the cell. Virus-infected host cells exhibit marked increases in glutamine utilization and metabolism. Glutamine metabolism generates ATP and precursors for the synthesis of macromolecules to assemble progeny viruses. Some compounds derived from glutamine are used in the syn thesis of purines and pyrimidines. These latter compounds are precursors for the synthesis of nucleotides. Inhibitors of glutamine transport and metabolism are potential candidate antiviral drugs. Glutamine is also an essential nutrient for the functions of leukocytes (lymphocyte, macrophage, and neutrophil), including those in virus-infected patients. The increased glutamine requirement for immune cell functions occurs concomitantly with the high glutamine utilization by host cells in virus-infected patients. The development of antiviral drugs that target glutamine metabolism must then be specifically directed at virus-infected host cells to avoid negative effects on immune functions. Therefore, the aim of this review was to describe the landscape of cellular glutamine metabolism to search for potential candidates to inhibit glutamine transport or glutamine metabolism.

Effect of homonuclear boron bonds in the adsorption of DNA nucleobases on boron nitride nanosheets

Quantum-mechanics calculations were carried out within the density functional theory (DFT) scheme, to analyze the sorbate-sorbent interaction between DNA nucleobases (purines: guanine and adenine; pyrimidines: cytosine and thymine) and hexagonal boron nitride nanosheets (pristine and non-stoichiometric) in two phases: i) gas and ii) aqueous. The resulting molecular simulations for the pristine nanosheet indicate that the four molecular sorbates prefer to be oriented perpendicular and/or parallel respect to sorbent. This geometrical effect generates adsorption energies associated to non-covalent interactions (physisorption), being the preferential adsorption sites those of N atoms of the nanosheet. According to the calculated quantum descriptors, they exhibit low chemical reactivity and work function, as well as high polarity and semiconductor-like behavior. However, the homonuclear boron bonds in the nanosheet (negatively charged) induce a strong interaction, almost three times larger than pristine nanosheet in gas phase; except for cytosine, due to this is weakly adsorbed in both phases. Moreover, the chemical reactivity and work function are reduced, whereas its conductivity (energy LHgap) and polarity were increased, since the preferential interaction site is corresponding to a B atom. Since the magnetic behavior (1.0 bohr magneton) of BN nanosheet/rB is not altered, the nanosheets with homonuclear boron bonds might be used as potential drug delivery vehicles and sensors.

Thermal Decomposition of 1,3,5,5-Tetranitrohexahydro-Pyrimidine: A New Type of Autocatalysis that Persists at High Temperatures

The thermal stability of 1,3,5,5- tetranitrohexahydropyrimidine (TNDA) in liquid phase under isothermal conditions was studied. It was established that the TNDA decomposition (k(liq)=3.1 . 10(21).exp(-26865/T), E-a=223.4 kJ mol(-1)) is accompanied by strong autocatalysis (k(cat)=9.8 . 10(14).exp(-18056/T), E-a=150.2 kJ mol(-1)). The mechanism of autocatalysis was proposed. The essence of autocatalysis is the oxidation of TNDA by decomposition products, followed by the destruction of the molecule. An unusual feature of this autocatalysis is that, in contrast to autocatalysis of nitroesters, the process does not disappear at high temperatures, but rather determines the kinetics of heat release in the combustion wave. The surface temperature and combustion mechanism of TNDA were established through thermocouple studies. It was shown that the autocatalysis reaction at the surface temperature controls the burning rate.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 274693-26-4 is helpful to your research. SDS of cas: 274693-26-4.

Functional characterization of the HMP-P synthase of Legionella pneumophila (Lpg1565)

The production of the pyrimidine moiety in thiamine synthesis, 2-methyl-4-amino-5-hydroxymethylpyrimidine phosphate (HMP-P), has been described to proceed through the Thi5-dependent pathway in Saccharomyces cerevisiae and other yeast. Previous work found that ScThi5 functioned poorly in a heterologous context. Here we report a bacterial ortholog to the yeast HMP-P synthase (Thi5) was necessary for HMP synthesis in Legionella pneumophila. Unlike ScThi5, LpThi5 functioned in vivo in Salmonella enterica under multiple growth conditions. The protein LpThi5 is a dimer that binds pyridoxal-5 ‘-phosphate (PLP), apparently without a solvent-exposed Schiff base. A small percentage of LpThi5 protein co-purifies with a bound molecule that can be converted to HMP. Analysis of variant proteins both in vivo and in vitro confirmed that residues in sequence motifs conserved across bacterial and eukaryotic orthologs modulate the function of LpThi5. Importance Thiamine is an essential vitamin for the vast majority of organisms. There are multiple strategies to synthesize and salvage this vitamin. The predominant pathway for synthesis of the pyrimidine moiety of thiamine involves the Fe-S cluster protein ThiC. An alternative pathway utilizes Thi5, a novel enzyme that uses PLP as a substrate. The Thi5-dependent pathway is poorly characterized in yeast and has not been characterized in Bacteria. Here we demonstrate that a Thi5-dependent pathway is necessary for thiamine biosynthesis in Legionella pneumophila and provide biochemical data to extend knowledge of the Thi5 enzyme, the corresponding biosynthetic pathway, and the role of metabolic network architecture in optimizing its function.

Boosting the catalytic performance of zinc linked amino acid complex as an eco-friendly for synthesis of novel pyrimidines in aqueous medium

Zinc linked amino acid complex, Zn(l-proline)(2), is considered as a green catalyst for the synthesis of novel series of pyrimidine derivatives 5a-q. The pyrimidines 5a-q were prepared via two pathways: the first is a one-pot reaction of guanidines 3(a-c) with aromatic aldehyde 1 and acetophenones 2; and the second one is the reaction of guanidines 3(a-c) with different chalcones 4(a-j) in aqueous medium. The simplicity of the operation, the short reaction time, and the high efficiency (97%) are the main advantages of this protocol. Furthermore, the green aspects of this synthetic protocol were further investigated by examining the reusability of Zn(l-proline)(2) complex throughout five consecutive cycles without a significant loss of catalytic activity. This new procedure has presented remarkable advantages in terms of safety, simplicity, stability, mild conditions, a short reaction time, excellent yields, and high purities without using any organic solvents.

A high density and insensitive fused [1,2,3]triazolo-pyrimidine energetic material

A novel fused triazolo-pyrimidine energetic compound was synthesized by the two-step diazotization-nitrification method or one-step direct nitration reaction. The physical properties and detonation properties of intermediate 3H-[1,2,3]triazolo[4,5-d]pyrimidine-5,7-diamine (2) and N-(7-oxo-6,7-dihydro-2H-[1,2,3]triazolo[4,5d]pyrimidin-5-yl)nitramide (3) were further explored. Compound 2 has a higher decomposition temperature (368 degrees C) than that of 2,4,6-trinitrotoluene (TNT, 295 degrees C). X-ray crystal-structure analysis shows that the density of compound 3 was 1.97 g cm(-3) at 100 K. Not only the detonation performance of compound 3 (8845 m s(-1), 32.54 GPa) was predicted to approach RDX (8795 m s(-1), 34.9 GPa) but displays significantly good safety properties (36 J), which means that compound 3 may serve as a potential high energy insensitivity material (HEIM).

The copper(II) complexes of new anthrahydrazone ligands: In vitro and in vivo antitumor activity and structure-activity relationship

Two new copper(II) complexes, 9-PMAH-Cu (1) and 9-FPMAH-Cu (2), of anthrahydrazone were synthesized and structurally characterized, in which 9-FPMAH (9-(4′-trifluoromethyl)-pyrimidine anthrahydrazone) is the 4′-CF3 derivative of 9-PMAH (9-pyrimidine anthrahydrazone). Both complexes 1 and 2 showed similar intercalative binding modes towards DNA and might compete with the typical DNA intercalator, GelRed, in the same binding site. They could also act as topoisomerase (type I) suppressor to effectively inhibit its activity, in which complex 1 was more effective than 2. The in vitro antitumor screening indicated that complex 1 displayed much higher antiproliferative ability than 2 and cisplatin towards all the tested tumor cell lines. On the other hand, complex 1 also showed high cytotoxicity against human normal liver cell line HL-7702, suggesting it is a potential high cytotoxic antitumor candidate. While it was also suggested that the loss of activity of complex 2 might be due to the presence of 4′-CF3 on the pyrimidine ring. Studies on the cellular level showed that complex 1 could arrest the cell cycle of the most sensitive T-24 cells at G2/M phase and induced cell apoptosis. Complex 1 further showed a significant suppression on the tumor growth on the T-24 tumor xenograft mouse model, but not reduced the body weight. Especially, complex 1 could retain its coordination state in H2O even in the presence of HSA. The results suggests that complex 1 is of enough safety to be considered as a promising anticancer candidate by combining the bioactive Cu(II) and the anthrahydrazone pharmacophore.

Synthesis and antiproliferative assessments of new derivatives of isothiazolo[3,4-d]pyrimidine

Various derivatives of 5-aryl-4-imino-3-(phenylamino)-4,5-dihydroisothiazolo[3,4-d]pyrimidines (3a-f) were synthesized. The synthesis has been done through treatment of 3-amino-4-cyano-5-(phenylamino)isothiazole with various aryl isothiocyanates. The isothiazole skeleton was obtained by the reaction of malononitrile and phenyl isothiocyanate followed by chloramine treatment. Some of the synthesized dihydroisothiazolo[3,4-d]pyrimidines were tested against different cancer cell lines, including ACHN, HeLa, HL-60, MCF-7, and PC3. Malignant cells were cultured in RPMI medium and incubated with different concentrations of the mentioned compounds. Cell viability was assessed using the MTS assay. The cytotoxicities of the synthesized compounds are not significant and are probably safe for other biological use.
