Synthesis, photophysical and nonlinear optical properties of [1,2,5] oxadiazolo[3,4-b]pyrazine-based linear push-pull systems

A series of D-pi-A chromophores based on [1,2,5]oxadiazolo[3,4-b]pyrazine electron-withdrawing group has been designed. The influence of the pi-conjugated linker (1,4-phenylene and 2,5-thienylene) and the amino-electron-donating group (diphenylamino and carbazol-9-yl) was studied by cyclic voltammetry, UV-Vis and emission spectroscopy. The second order nonlinear optical properties were also studied using the electric field induced second harmonic generation (EFISH) method. The experimental results have been rationalized by theoretical DFT calculations.

Fabrication of (4,10) and (4,12)-Connected Multifunctional Zirconium Metal-Organic Frameworks for the Targeted Adsorption of a Guest Molecule

Following the principle of a topology guide, a zirconium MOF (PCN-207) based on the H(4)TPTA ligand (tetramethyl(4,4′,4 ”,4′-(pyrazine-2,3,5,6-tetrayl))-tetrabenzoic acid) with C-2 symmetry and an 8-connected Zr-6(mu(3)-OH)(8)(OH)(8)](8+) cluster with D-4h symmetry has been synthesized. PCN-206 can also be obtained by modulating the benzoic acid usage to change the flexibility of the H(4)TPTA ligand. The unique positions of 8-connected Zr-6 clusters in the flu and scu networks and the flexibility of the tetratopic primary linker enable the precise insertion of fumarate (FA), 1,4-benzenedicarboxylic acid (H2BDC), and even 2,6-naphthalenedicarboxylic acid (H2NDC) in a one-pot reaction. Auxiliary linkers are used to generate new MOF structures or topologies or to split the pore spaces, which may significantly change the porosity and chemical and physical properties of scaffold MOFs. The results provide a successful strategy for the rational design of multicomponent Zr-MOFs. Because of differences in composition and configuration between structures, PCN-207 shows the highest separation capability of light hydrocarbons; moreover, PCN-206 exhibits the highest adsorption capacity of 2,4-D and DCF among MOFs at present.

Theoretical study on the intermolecular interactions between energetic oxidizer and pyrazine-1, 4-dioxide

Based on density functional theory (DFT), the intermolecular interaction between two kinds of energetic oxidizer (ammonium perchlorate (AP) and ammonium dinitramide (ADN)) and pyrazine – 1, 4 – dioxide (PDO) was studied. Under the calculation level of B3LYP // 6-311++G**, three AP-PDO complexes and six ADN-PDO complexes were optimized to obtain their stable structures. Electron density topological analysis and reduced density gradient analysis were used to analyze the types of intermolecular interaction. The change of electrostatic potential (ESP) before and after the formation of the composite was compared, and the oxygen balance of the composite was analyzed at different molar ratios. The results show that both AP-PDO and ADN-PDO have hydrogen bonds and van der Waals interactions between the two compounds, and there was hope for the synthesis of cocrystallization. After the formation of the complex, the Vs, max of electrostatic potential was decreased compared with the simple substance. According to the oxygen balance performance, the optimal molar ratios of AP-PDO and ADN-PDO for cocrystal formation were 3:2 and 2:1, and the oxygen balance were -1.4 % and 0, respectively. The results are helpful for the application of cocrystallization technique in the field of ionic salt containing energy.

Broad-spectrum antimicrobial activity of Streptomyces griseus BLS4, a newly isolated endophyte of Blumea lacera

Endophytic actinomycetes are a group of gram-positive bacteria with high G+C content found as active producers of diverse compounds inside plant tissues. In this study, endophytic actinomycetes have been isolated from Blumea lacera, an important ethnomedicinal plant with antimicrobial properties using culture dependent methods. Preliminary investigation for antimicrobial activity revealed the isolate BLS4 as the most promising isolate giving inhibition zones against 11 pathogenic bacterial strains and 2 plant pathogenic fungal strains. MIC of the crude extract of the actinomycetes was determined against the previously stated pathogens. Morphological characters were noted and depending upon sequence analysis of 16s rDNA, the isolate has been named Streptomyces griseus strain BLS4. Study of its genome for the presence of PKs gene (type-I) affirmed that it carries the gene family that is responsible for synthesis of antimicrobial compounds in the Streptomyces species. For purification and characterization of the active compounds, TLC, bioautography and column chromatography of ethyl acetate extract of culture broth of BLS4 and GC-MS analysis of purified fraction were performed. The GCMS study showed the presence of two antimicrobial compounds in highest abundance- Emimycin and Pyrrolo [1, 2-a] pyrazine-1, 4-dione, hexahydro-3-(2-methylpropyl). Several other organic compounds have also been identified. Optimum compound production was observed at 15 Days in TYG media. All these biochemical aspects of this novel actinomycetous isolate make it an able synthesizer of organic compounds which can find use in various industries.

Synthesis of new boswellic acid derivatives as potential antiproliferative agents

In the current investigation, a series of heterocyclic derivatives of boswellic acids were prepared along with new monomers of 3-O-acetyl-11-keto-beta-boswellic acid (AKBA,1) 11-keto-beta-boswellic acid (KBA,2) and several new bis-AKBA and KBA homodimers and AKBA-KBA heterodimers. The effects of these compounds on the proliferation of different human cancer cell lines, viz., FaDu (pharynx carcinoma), A2780 (ovarian carcinoma), HT29 (colon adenocarcinoma), and A375 (malignant melanoma), have been evaluated. Thus, KBA homodimer21effectively inhibited the growth of FaDu, A2780, HT29, and A375 cells with EC(50)values below 9 mu M. In addition, compounds7,8,11,12,15,16,and17also exhibited cytotoxic effects for A2780, HT29, and A375 cancer cells. In particular, the pyrazine analog8was highly cytotoxic for A375 cancer cells with an EC(50)value of 2.1 mu M.

2-Pyrazine-PPD, a novel dammarane derivative, showed anticancer activity by reactive oxygen species-mediate apoptosis and endoplasmic reticulum stress in gastric cancer cells

20 (R)-Dammarane-3 beta, 12 beta, 20, 25-tetrol (25-OH-PPD), a ginsenoside, was derived from Panax ginseng (C. A. Meyer) and inhibited growth of several cancer cell lines. To improve the anti-cancer activity, we introduced the pyrazine ring to 25-OH-PPD and obtained the compound 20(R)-[2,3-beta]-Pyrazine-dammarane-12 beta,20,25-triol (2-Pyrazine-PPD). we evaluated the anti-cancer activity of 2-Pyrazine-PPD and investigated the main anti-cancer mechanisms of 2-Pyrazine-PPD in gastric cancer cells. We found that 2-Pyrazine-PPD remarkably suppressed the proliferation of gastric cancer cells in a concentration-dependent, and showed little toxicity to the normal cell (human gastric epithelial cell line-GES-1). Further study indicated that 2-Pyrazine-PPD induced apoptosis by mitochondria pathway in BGC-803 cancer cells, and activated unfolded protein response and the protein kinase RNA-activated (PKR)-like ER kinase (PERK)/Eukaryotic translation initiation factor-2 alpha (eIF-2 alpha)/Activating transcription factor 4 (ATF4) axis, the expression level of the protein C/EBP homologous protein (CHOP), the marker of endoplasmic reticulum stress, and the apoptosis inducing by 2-Pyrazine-PPD can partly be inhibited by siRNA-mediated knockdown of CHOP. Moreover, the production of reactive oxygen species was remarkably up-regulated in BGC-803 cancer cells treated with 2-Pyrazine-PPD. N-acetylcysteine (NAC, a reactive oxygen species scavenger) can attenuate 2-Pyrazine-PPD-induced apoptosis and endoplasmic reticulum stress. Taken together, we suggested that 2-Pyrazine-PPD exhibited remarkable anti-cancer activity by reactive oxygen species-mediate cell apoptosis and endoplasmic reticulum stress in gastric cancer cells. Our results uncovered the mechanism of 2-Pyrazine-PPD as a promising anti-tumor candidate for gastric cancer therapy.

Volatile fingerprinting of ripened cheese for authentication and characterisation of different dairy systems

Authentication of dairy systems is of growing interest for the dairy industry and we investigated the potentiality of using volatile fingerprinting of ripened cheeses by proton transfer reaction time-of-flight mass spectrometry. A total of 1,075 individual model cheeses made from milk of individual Brown Swiss cows of 72 farms were analysed. Using a linear discriminant analysis, cows and herds were assigned to 3 or 5 dairy systems differing in management, available facilities, and diets. We obtained variable discrimination abilities (up to 77% of correct classification of cheeses and 70% of farms with cross-validation). We found m/z 61,028 (acetic acid), 109,070 (pyrazine), and m/z 137,132 (terpene) characterising model cheeses from traditional dairy systems and m/z 71,086 (3-methyl-butan-1-ol, 3-methyl-3-buten-1-ol, pentan-1-ol), m/z 101,097 (hexan-2-one, hexanal), m/z 123,117 (nonenal), m/z 129,127 (octan-1-one, octanal), and two unidentified peaks m/z 83,071 and m/z 93,090 characterising model cheeses from the modern farms. In conclusion, it seems possible to discriminate between a range of dairy systems using fast volatile fingerprinting of ripened cheeses but a proper validation of results obtained is needed.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 2847-30-5, you can contact me at any time and look forward to more communication. Recommanded Product: 2847-30-5.

Diarylpyrazine-based position isomers: A detailed study of optical properties and structure-property relationship

A versatile and expeditious synthetic route to pyrazine-based symmetric and asymmetric chromophores decorated with donor-acceptor (D-A) has been designed to study their structural effects on optical properties. Suzuki-Miyaura coupling of dihalopyrazine with various aryl boronic acids was synthesized under microwave condition. Pyrazine functionalized at C-2, C-5 and C-6 serve as acceptor to construct linear and angular push-pull chromophores. The photophysical, electrochemical and thermal properties of all the target chromophores were systematically investigated and the results were correlated theoretically by density functional theory computations. The emission wavelength was significantly red-shifted by introduction of strong electron withdrawing group (CN). The permutation of terminal donor acceptor units tunes the optoelectronic properties in a predictable way, aiding in the rational design of small molecule for luminescent materials. These chromophores displayed multicolour change in different solvents, exhibiting good solvatochromism with a large Stokes shift.

C = C-Ene-Reductases Reduce the C = N Bond of Oximes

Although enzymes have been found for many reactions, there are still transformations for which no enzyme is known. For instance, not a single defined enzyme has been described for the reduction of the C = N bond of an oxime, only whole organisms. Such an enzymatic reduction of an oxime may give access to (chiral) amines. By serendipity, we found that the oxime moiety adjacent to a ketone as well as an ester group can be reduced by ene-reductases (ERs) to an intermediate amino group. ERs are well-known enzymes for the reduction of activated alkenes, as of alpha,beta-unsaturated ketones. For the specific substrate used here, the amine intermediate spontaneously reacts further to tetrasubstituted pyrazines. This reduction reaction represents an unexpected promiscuous activity of ERs expanding the toolkit of transformations using enzymes.

Influence of Excipients on Cocrystal Stability and Formation

Cocrystal formation is widely used to modify and optimize the physicochemical properties of an active pharmaceutical ingredient (API). However, the stability of cocrystals toward formulation with excipients is little investigated. In this work, the effect of grinding in the presence of the common excipients polyvinylpyrrolidone (PVP) and microcrystalline cellulose (MCC) on 11 cocrystals and a salt of the sulfonamide diuretic chlorothiazide (ctz) was studied (ctz-bipy, ctz-ebipy, ctz-pbipy, ctz-pyr, ctzhyp, ctz-hma, ctz-bza, ctz-nia, ctz-ina, ctz-cbz, ctz-aca, ctz-ppa, (bzamH(+))(ctz(-)); bipy = 4,4′-bipyridine, ebipy = 1,2-di(4-pyridyl)ethylene, pbipy = 1,3-di(4-pyridyl)propane, pyr = pyrazine, hyp = 2-hydroxypyridine, hma = hexamethylenetetramine, bza = benzamide, nia = nicotinamide, ina = isonicotinamide, cbz = carbamazepine, aca = acetamide, ppa = propionamide, bzamH+ = benzamidinium). Except for ctz-ppa and ctz-aca, all cocrystals were stable toward milling with 1 weight equiv PVP or MCC. It was also shown that the cocrystals ctz-bipy, ctz-ebipy, ctz-pbipy, ctz-pyr, ctz-hma, ctz-bza, ctz-ina, ctz-cbz, and the salt (bzamH+)(ctz-) formed in situ, when ctz was milled with the respective coformer in the presence of PVP or MCC. The stability and formation of ctz-cbz, ctz-nia, and htz-nia (htz = hydrochlorothiazide) toward grinding with a wider range of excipients (HPC, alpha-lactose, deoxycholic acid, and sodium taurocholate) was also investigated, and the results are discussed with regard to the heterosynthons of the ctz cocrystals and competing H bonding with the excipients.
