Blueberry, raspberry, and strawberry extracts reduce the formation of carcinogenic heterocyclic amines in fried camel, beef and chicken meats

Heterocyclic amines (HCAs) are toxic products from the Maillard reaction that form from the reaction of sugars, amino acids and creatine/creatinine when cooking protein rich food. In this work, commonly consumed meats in Saudi Arabia (camel, beef and chicken) were fried under conditions resembling home cooking. The effect of marinades made of blueberry, raspberry and strawberry were tested separately on meat at different marinating times (1, 6, 12, 24h, at 4 degrees C) before frying. The marinades caused an overall reduction of HCAs. The decrease was more noticeable with long marination time >= 6h. The reduction of individual HCAs, after 24h marinades, was 91-100% for pyridines; 40-67% for beta-carbolines; and 100% for quinoxalines, quinolines, alpha-carbolines and gamma-carbolines, although the latter three were seldomly detected in this study. An increase, up to 2 times, on the formation of the studied quinoxalines was observed in every meat and marination for no more than 1h. Therefore, longer marinating times with berry extracts, from 6h, are recommended over those below (1h).

Design and synthesis of a solvent-dependent fluorescent probe for dual selective detection of Mg2+ ion and Zn2+ ion

A solvent-dependent fluorescent probe QC for the dual detection of Mg2+ ion and Zn2+ ion has been constructed based on a Schiff base compound, in which 8-hydroxyquinoline served as not only a fluorophore but also a recognition group. Among the various tested metal ions, this probe exhibited high sensitivity and good selectivity toward Mg2+ ion in acetonitrile and Zn2+ ion in EtOH-H2O (9:1, v/v), respectively. With the treatment of Mg2+ ion or Zn2+ ion, 1:2 complex was formed between QC and Mg2+ ion, which inhibited the PET processes caused by the lone pair electrons from the nitrogen atom of the -C = N group and the nitrogen atom of quinoline moiety, resulting in the fluorescence enhancement for Mg2+ ion. Whereas a 1:1 complex was formed between QC and Zn2+ ion, which inhibited the PET process only caused by the lone pair electrons from the nitrogen atom of the -C = N group, resulting in the fluorescence enhancement at a shorter wavelength. The detection limit was calculated as low as 6.28 x 10(-8) M for Mg2+ ion and 2.36 x 10(-7) M for Zn2+ ion. DFT analysis further supported this concept to design the probe.

Facile nucleophilic substitution of coordinated acetonitrile in trans-[PtCl4(NCMe)(PPh3)]

( )Despite the generally accepted inertness of platinum(IV) complexes towards nucleophilic substitution, the title compound promptly reacts with nucleophiles L (L = pyridine, quinoline, isoquinoline, benzothiazole, o-, m-, ptoluidine) affording the corresponding acetonitrile substitution products. To follow the reaction spectroscopically, a series of platinum(IV) standards were prepared by bridge splitting of trans-[Pt(mu-Cl)Cl(PPh3)](2), followed by oxidation by PhICl2. All the new platinum(II) and platinum(IV) complexes were fully characterized, and, in some cases, the structure was studied by single crystal X-ray diffraction. Even when protic o-, m- and p-toluidines were used, chemoselectivity towards substitution was observed, with addition products formed in less than 10% extent.

Chiral Pd-Catalyzed Enantioselective Syntheses of Various N-C Axially Chiral Compounds and Their Synthetic Applications

Biaryl atropisomers are key structural components in chiral ligands, chiral functional materials, natural products, and bioactive compounds, and their asymmetric syntheses have been reported by many groups. In contrast, although the scientific community has long been aware of atropisomers due to rotational restriction around N-C bonds, they have attracted scant attention and have remained an unexplored research area. In particular, their catalytic asymmetric synthesis and the synthetic applications were unknown until recently. This Account describes studies conducted by our group on the catalytic enantioselective syntheses of N-C axially chiral compounds and their applications in asymmetric reactions. In the presence of a chiral Pd catalyst, the reactions of achiral secondary ortho-tert-butylanilides with 4-iodonitrobenzene proceeded in a highly enantioselective manner (up to 96% ee), affording N-C axially chiral N-arylated ortho-tert-butylanilides in good yields. The application of the present chiral Pd-catalyzed N-arylation reaction to an intramolecular version gave N-C axially chiral lactams with high optical purity (up to 98% ee). These reactions were the first highly enantioselective syntheses of N-C axially chiral compounds with a chiral catalyst. Since the publication of these reactions, N-C axially chiral compounds have been widely accepted as new target molecules for catalytic asymmetric reactions. Furthermore, chiral-Pd-catalyzed intramolecular N-arylations were applied to the enantioselective syntheses of N-C axially chiral quinoline-4-one and phenanthridin-6-one derivatives. We also succeeded in the enantioselective syntheses of various N-C axially chiral compounds using other chiral Pd-catalyzed reactions. That is, optically active N-C axially chiral N-(2-tert-butylphenyl)indoles, 3-(2-bromophenyl)quinazolin-4-ones, and N-(2-tert-butylphenypsulfonamides were obtained through chiral Pd-catalyzed 5-endo-hydroaminocyclization, monohydrodebromination (reductive asymmetric desymmetrization), and Tsuji-Trost N-allylation, respectively. The study of the catalytic asymmetric synthesis of axially chiral indoles has contributed to the development of not only N-C axially chiral chemistry but also the chemistry of axially chiral indoles. Subsequently, the catalytic asymmetric syntheses of various indole derivatives bearing a C-C chiral axis as well as an N-C chiral axis have been reported by many groups. Moreover, axially chiral quinazlolin-4-one derivatives, which were obtained through chiral Pd-catalyzed asymmetric desymmetrization, are pharmaceutically attractive compounds; for example, 2-methyl-3-(2-bromophenyl)quinazolin-4-one product is a mebroqualone possessing GABA agonist activity. Most of the N-C axially chiral products have satisfactory rotational stability for synthetic applications, and their synthetic utility was also demonstrated through application to chiral enolate chemistry. That is, the reaction of various alkyl halides with the enolate prepared from the optically active anilide, lactam, and quinazolinone products proceeded with high diastereoselectivity by asymmetric induction due to the N-C axial chirality. At the present time, N-C axially chiral chemistry has become a popular research area, especially in synthetic organic chemistry, and original papers on the catalytic asymmetric syntheses of various N-C axially chiral compounds and their synthetic applications have been published.

Synthesis and Photophysical Properties of a Series of Dimeric Indium Quinolinates

A novel class of quinolinol-based dimeric indium complexes (1-6) was synthesized and characterized using H-1 and C-13(H-1) NMR spectroscopy and elemental analysis. Compounds 1-6 exhibited typical low-energy absorption bands assignable to quinolinol-centered pi-pi* charge transfer (CT) transition. The emission spectra of 1-6 exhibited slight bathochromic shifts with increasing solvent polarity (p-xylene < tetrahydrofuran (THF) < dichloromethane (DCM)). The emission bands also showed a gradual redshift, with an increase in the electron-donating effect of substituents at the C5 position of the quinoline groups. The absolute emission quantum yields (phi(PL)) of compounds 1 (11.2% in THF and 17.2% in film) and 4 (17.8% in THF and 36.2% in film) with methyl substituents at the C5 position of the quinoline moieties were higher than those of the indium complexes with other substituents.

An expeditious microwave assisted one-pot sequential route to pyrido fused imidazo[4,5-c] quinolines in green media

An expeditious microwave assisted one-pot sequential route to synthesize pyrido fused imidazo[4,5-c]quinolines via the Pictet-Spengler cyclization strategy has been developed. In this study, substituted 2-amino pyridines are condensed with 2-bromo-2 ‘-nitroacetophenone to generate imidazo[1,2-a]pyridines with nitro group functionality at C-2 position. Reduction of nitro group to its amine congener in green media followed by the Pictet-Spengler cyclization strategy with substituted aldehydes led to the formation of new C-C and C-N bonds in a one-pot sequential manner. The cyclization proceeds through the CO(carbonyl)-C(H) cleavage of the aldehyde group via oxidative cross-coupling, transamination, cyclization and aromatization steps. Low cost reagents and a green solvent were used to facilitate the architecturally beautiful pyrido fused imidazo[4,5-c]quinoline scaffolds in high yields. The key features of this synthetic protocol are the use of microwave-assisted mild reaction conditions, one-pot sequential pathway, broad substrate scope and green media, which make it feasible for the synthesis of fused polyheterocycles. Moreover, the synthetic manipulation proceeded well with heteroaromatic and aliphatic aldehydes also in good yields.

A novel quinoline-based turn-on fluorescent probe for the highly selective detection of Al (III) and its bioimaging in living cells, plants tissues and zebrafish

A novel quinoline fluorescent probe QNP ((E)-N ‘-(5-chloro-2-hydroxybenzylidene) quinoline-2-carbohydrazide) for detection of Al3+ ion was designed, synthesized and characterized. QNP displayed a high fluorescence enhancement in the presence of Al3+ ion in DMF:PBS (99:1, v/v) solution and the detection limit was as low as 1.25 mu M with high selectivity and excellent sensitivity from 0 to 3 mu M. The sensing ability of QNP towards Al3+ ion is attributed to the synergistic effect of PET and ICT. Furthermore, the binding stoichiometry between QNP and Al3+ ion is of 1:1 by Job’s plot and mass spectrum, and the calculated binding constant is 4.29 x 10(8) M-1. The detection of Al3+ ion in water samples illustrates that QNP could be applied to the detection of practical samples in the environment. Bioimaging experiments on Hela cells, zebrafish and soybean root tissues demonstrate that it has potential application to investigate biological processes involving Al3+ ion within living cells.
