New nodularins: A general method for structure assignment

A general method has been developed for assigning the structures of nodularin, a potent hepatotoxin, tumor promoter, and protein phosphatase inhibitor, and minor components isolated from a cultured and a bloom sample of the cyanobacterium Nodularia spumigena. It consists of (1) FABMS analysis (determination of molecular weight and molecular formula), (2) 1H NMR spectroscopy on the parent compound and chiral GC analysis of an acid hydrolyzate (identification and stereochemistry of amino acid components), (3) ozonolysis followed by NaBH4 reduction (conversion to a linear peptide), and (4) FABMS/CID/MS analyses of the linear peptide and the parent compound (sequence analysis). The method has been employed in assigning structures to three new nodularins (2-4) and can be applied to other cyclic peptides containing alpha,beta-dehydroamino acid unit(s), especially the related microcystins, cyclic heptapeptide hepatotoxins. Two nodularins, [DMAdda3]nodularin (2) and [(6Z)Adda3]nodularin (3), were obtained from a bloom sample collected from Lake Ellesmere (New Zealand), and [D-Asp1]nodularin (4) was isolated from cultured cells (strain L-575). The LD50s of 2 and 4 were 150 and 75 mug/kg (ip, mice), respectively, but 3 did not show apparent toxicity at 2.0 mg/kg.

Discovery of a Potent and Selective Sphingosine Kinase 1 Inhibitor through the Molecular Combination of Chemotype-Distinct Screening Hits

Sphingosine kinase (SphK) is the major source of the lipid mediator and G protein-coupled receptor agonist sphingosine-1-phosphate (S1P). S1P promotes cell growth, survival, and migration and is a key regulator of lymphocyte trafficking. Inhibition of S1P signaling has been proposed as a strategy for treatment of inflammatory diseases and cancer. Two different formats of an enzyme-based high-throughput screen yielded two attractive chemotypes capable of inhibiting S1P formation in cells. The molecular combination of these screening hits led to compound 22a (PF-543) with 2 orders of magnitude improved potency. Compound 22a inhibited SphK1 with an IC50 of 2 nM and was more than 100-fold selective for SphK1 over the SphK2 isoform. Through the modification of tail-region substituents, the specificity of inhibition for SphK1 and SphK2 could be modulated, yielding SphK1-selective, potent SphK1/2 dual, or SphK2-preferential inhibitors.

Physicochemical characterization of Theobroma cacao L. sweatings in Ecuadorian coast

In 2014, Ecuador generated 141,000 MT of cocoa sweatings equivalent to 12,320 MT of reducing sugars that through fermentation can become Bioetanol. Cocoa sweatings was characterized to determinate its potential as biofuel. Methodologies described by AOAC 2005 standards were used. Values of 10.6 Brix; pH 3.58; density 1.10 g/ml, total sugars 12,33% reducing sugars 6.39% were observed. Chemical groups such as alkaloids, reducing sugars, and coumarins triterpenoid were identified by phytochemical screeninng. 20 chemical compounds were detected using by gas chromatography mass spectrometry (GC-MS): 3 carboxilic acids, 4 sugar acids, 3 sugar alcohols, 2 amino acids, 1 furan, 2 lactones, 1 monosaccharides, 2 disaccharides and 2 glycosides. They represent the 11.08% of total compounds separated, and Sucrose (2.15%), glucose (2.13%) and fructose (4.42%) were identified by high performance liquid chromatography (HPLC). The study showed that for each kilogram of dry cocoa produced 0.59 kg of mucilage are obtained and its sugars are an interesting source of raw material for the production of second generation bioethanol, results that contribute to reducing the environmental impact that generate these waste.

Peach growth cycle monitoring using an electronic nose

In regions with the predominance of agriculture, an inspection of the quality and fruit maturity index in the orchard is usually analyzed by the farmer’s experience, which can be subject to errors and generate a greater cost of time and money. Thus, monitoring equipment that generates a rapid and accurate response to the growth cycle of the peaches in the crop is desirable, together with a low marketing cost. For this purpose, electronic noses prove to be the most suitable equipment, since it allows online monitoring of the VOCs (Volatile Organic Compounds) generated by the crop. In this context, a prototype was developed to perform the classification of the fruit growth cycle (pre-harvest and post-harvest). Models with the 13 gas sensors made with a metal oxide semiconductor (MOS) and the reduction to 7 sensors were studied with the aid of the Pearson’s Chi-square test, for comparison. Samples with 4 growth stages were used for the training and construction of the model. The accuracy of 99.23% in the validation step and 98.08% in the sample test step using the Random Forest method with linear discriminant analysis for the reduced data set for 7 sensors shows that the device is promising for monitoring of areas with an intense emission of VOCs.
