Determination of bioactive chemical composition of callosobruchus maculutus and investigation of its anti-fungal activity

Methanolic extract of bioactive compounds of Callosobruchus maculutus was assayed for in vitro anti-fungal activity against Aspergillus niger, Aspergillus terreus, Aspergillus flavus, Aspergillus fumigatus, Candida albicans, Saccharomyces cerevisiae, Penicillium expansum, and Trichoderma viride.

The Mechanism of Thermal Eliminations. Part 21. Rate Data for Pyrolysis of 2-Ethoxyquinoline, 1-and 3-Ethoxyisoquinoline, and 1-Ethoxythiazole: Correlation of Reactivities with ?-Bond Order of the C=N Bond

We have measured the rates of thermal elimination of ethylene from the title compounds between 587.3 and 722.9 K.The reactivities relative to 2-ethoxypyridine at 650 K are: 3-ethoxyisoquinoline (0.21), 2-ethoxyquinoline (3.13), 1-ethoxyisoquinoline (6.47), 2-ethoxythiazole (63.1).These reactivities parallel the ?-bond order of the C=N bond, though the exceptional reactivity of 2-ethoxythiazole is attributed to additional acceleration through +M electron release from sulphur to nitrogen.This emphasizes the greater relative importance of nucleophilic attack by the nitrogen upon the beta-hydrogen atom as compared with the analogous mechanism for pyrolysis of esters.Because of semi-concentrated nature of the reaction, interruption of aromaticity is much less significant than in, for example, electrophilic aromatic substitution.Thus retention of the benzenoid character of the ring not involved in the elimination is not an important rate-determining feature, as shown by the lower reactivity of 3-ethoxyisoquinoline relative to 2- ethoxypyridine.The unimportance of the interruption of aromaticity of the benzenoid ring means that conjugative effects are better relayed to nitrogen in the beta-naphthalene-like position (isoquinoline) than in the alpha-naphthalene-like position (quinoline).This is the reverse of the familiar pattern for reactions of naphthalene-like systems where full charges are involved, and may be an additional factor contributing to the higher reactivity of 1-ethoxyisoquinoline than of 2-ethoxyquinoline, as may also be the -I effect of the benzo substiutent.The conclusions are used to predict elimination rates for alkoxyheterocycles not yet studied.

Design and development of some thiazole-based flavanoids as novel antibacterial against pathogens causing surgical site infection for possible benefit in bone trauma via inhibition of DNA gyrase

In this study, a novel class of hybrid thiazole-based flavanoid derivatives were synthesized and characterized by FT-IR, 1H-NMR, 13C-NMR, mass and elemental analysis. These derivatives were evaluated for antibacterial activity for possible benefit in bone trauma via inhibition of DNA gyrase enzyme. Results suggested that compounds 9n, 9o, and 9p showed considerable inhibition of DNA gyrase with considerable activity against tested forty strains of Staphylococcus aureus clinical isolates. Moreover, compound 9n showed hydrogen bonding with LYS460 along with low binding free energy of ?4.36 kcal/mol against DNA gyrase enzyme. The hemolytic activity of the potent compounds showed mild to no activity together with excellent pharmacokinetics, suggesting to have a potential for the development of designed compounds as novel antibacterial agents.

Viscosity-Dependent Decay Dynamics of the S2 State of Cyanine Dyes with 3, 5, and 7 Methine Units by Picosecond Fluorescence Lifetime Measurements

The lifetimes of the short-wavelength (SW) fluorescence of some cyanine dyes with 3, 5, and 7 methine units were measured using a synchronously pumped picosecond dye laser in conjunction with the time-correlated single-photon counting method. The lifetimes were longest for dyes with 5 methine units, and decreased in the order of 5, 7, and 3 methine units. The lifetimes were highly dependent on the solvent viscosity. The dependences were compared with those of the fluorescence quantum yields previously reported by the authors in order to determine the relative importance of direct internal conversion (viscosity-independent) relaxation channel and that of the crossing-over to the photoisomer potential energy curve (viscosity-dependent channel). It was determined that origin of the SW fluorescence was the second excited singlet state by semiempirical molecular orbital calculations. The absolute SW fluorescence quantum yield of one of the cyanine dyes, DODC, was found to be less than 0.002 in ethanol. The relaxation rates of these cyanine dyes in the first and second excited singlet states were compared.

The results of bioassay indicated that some of these title compounds exhibited 100% mortality at 50 mg/L against Aphis fabae. In particular, the compound 11c displayed the best activity: Its LC50 value achieved 1.45 mg/L, and its insecticidal potency is comparable with that of NC-510.

Cesium carbonate-promoted synthesis of aryl methyl sulfides using: S -methylisothiourea sulfate under transition-metal-free conditions

In the presence of cesium carbonate, an efficient synthesis of aryl methyl sulfides by the reactions of aryl halides with commercially available S-methylisothiourea sulfate is developed. This odourless and highly crystalline solid can be used as the substitute for malodorous methanethiol. The gram-scale reaction also proceeds smoothly without the use of column chromatography separation. Similarly, 2-(dimethylamino)ethylthio and cyclopropylmethylthio groups can be easily introduced into the aromatic rings from the corresponding S-[2-(dimethylamino)ethyl]isothiourea dihydrochloride and S-cyclopropylmethylisothiourea hydrobromide. The possible reaction mechanism is proposed. It is believed that this route to aryl alkyl sulfides is well competitive with currently known methods due to its wide substrate scope, excellent yields, easy operation and transition-metal-free conditions.

Discrimination between defective and non-defective Brazilian coffee beans by their volatile profile

The coffee roasted in Brazil is considered to be of low quality, due to the presence of defective coffee beans that depreciate the beverage quality. In view of the fact that coffee flavour is directly related to the volatile compounds produced during roasting, the objective of the present study was to perform a comparative evaluation of the volatile fraction of defective (black, immature, sour) and healthy coffee beans, in order to find possible chemical markers for detection of defective coffee beans in roasted coffee. Volatiles extraction and concentration was performed by solid phase micro-extraction (SPME) of the roasted coffee headspace, using a triple phase (divinylbenzene/carboxen/polydimethylsiloxane) fiber. Analysis of the volatile profiles was performed by GC-MS. The results obtained showed that the proposed methodology was adequate for extraction, concentration and analysis of the coffees volatile profile. Several substances were identified as possible markers for differentiating black, sour and immature beans from healthy coffee beans. Statistical analysis of the data by principal components (PCA) demonstrated that the volatile profile enables the differentiation of healthy and defective coffees. The data were separated into two major groups, one represented by immature and black beans and the other by healthy and sour coffee beans. Such results indicated that black and sour beans can be associated to fermentation of immature and of healthy beans, respectively.

The mechanism of peptide bonds cleavage and volatile compounds generated from pentapeptide to heptapeptide via Maillard reaction

This study is focused on the mechanism of peptide bond cleavage and volatile Maillard reaction products (MRPs) following reaction of 10 artificial oligopeptides with cysteine, xylose and thiamine. LC-TOF/MS was used to detect the chemistry of peptide bond cleavage in liquid media. GC-O-MS and a carbohydrate module labelling (CAMOLA) method were used to analyse and identify the formation pathways of volatile and semi-volatile MRPs. In this study, the theoretical foundation of seven principles of influencing factors acting on peptide chain cleavage has initially been summarised. At the start of this study assumptions were also made relating to heat resistance of peptide chain positions. A universal formation pathway map and a model of possible mechanisms of common product formation were proposed. This model was authenticated by this scientific study.
