Electric Literature of 125995-03-1. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 125995-03-1, Name is Atorvastatin lactone. In a document type is Article, introducing its new discovery.

Development, validation and application of a novel HPLC-MS/MS method for the quantification of atorvastatin, bisoprolol and clopidogrel in a large cardiovascular patient cohort

Cardiovascular disease is a leading cause of morbidity, mortality, and healthcare expenditure worldwide. Importantly, there is interindividual variation in response to cardiovascular medications, leading to variable efficacy and adverse events. Therefore a rapid, selective, sensitive and reproducible multi-analyte HPLC-MS/MS assay for the quantification in human plasma of atorvastatin, its major metabolites 2-hydroxyatorvastatin, atorvastatin lactone and 2-hydroxyatorvastatin lactone, plus bisoprolol and clopidogrel-carboxylic acid has been developed, fully validated, and applied to a large patient study. Fifty microliter plasma samples were extracted with a simple protein precipitation procedure involving acetonitrile with acetic acid (0.1%, v/v). Chromatographic separation was via a 2.7 mum Halo C18 (50 × 2.1 mm ID, 90 A) column and gradient elution at a flow rate of 500 muL/min consisting of a mobile phase of water (A) and acetonitrile (B), each containing 0.1% formic acid (v/v), over a 6.0 min run time. The six analytes and their corresponding six deuterated internal standards underwent positive ion electrospray ionisation and were detected with multiple reaction monitoring. The developed method was fully validated with acceptable selectivity, carryover, dilution integrity, and within-run and between-run accuracy and precision. Mean extraction recovery for the analytes was 92.7?108.5%, and internal standard-normalised matrix effects had acceptable precision (coefficients of variation 2.2?12.3%). Moreover, all analytes were stable under the tested conditions. Atorvastatin lactone to acid interconversion was assessed and recommendations for its minimisation are made. The validated assay was successfully applied to analyse 1279 samples from 1024 patients recruited to a cardiovascular secondary prevention prospective study.

Carbohydrate binding specificity of the recombinant chitin-binding domain of human macrophage chitinase.

The chitin-binding domain of human macrophage chitinase was expressed as a fusion protein with glutathione S-transferase in Escherichia coli and assayed for its binding activity. The purified recombinant chitin-binding domain bound to chitin, but not to glucan, xylan, or mannan. The binding of the recombinant chitin-binding domain to chitin was inhibited by N-acetylglucosamine, di-N-acetylchitobiose, and hyaluronan, but not by N-acetylgalactosamine or chondroitin. Furthermore, a solid-phase binding assay showed that the recombinant domain interacts specifically with hyaluronan and hybrid-type N-linked oligosaccharide chains on glycoproteins, and that the oligosaccharide-binding characteristics are similar to those of wheat germ agglutinin, a lectin that binds to chitin. The results suggest that human chitinase chitin-binding domain may be involved in tissue remodeling through binding to polysaccharides or extracellular matrix glycoproteins, and this recombinant protein can be used to elucidate biological functions of the enzyme.

Glycosylidene Carbenes, Part 9: Regioselective Glycosidation of Diols and Triols: Intra- and Intermolecular Hydrogen Bonds

Glycosidation of the myo-inositol derivatives 2 and 3 by the diazirine 1 yields 90percent of a diastereoisomer pair of beta-D-glycosides in a 1:1 ratio, i.e. 5/6 and 7/8, respectively (Scheme 1).The crystal structure of 3 shows a strong intramolecular H-bond, which persists in solution, as indicated by FT-IR and 1H-NMR spectra.Yields and diastereoselectivity are lower for the glycosidation of 24 by 1 (Scheme 3).The resulting 1,2- and 1,4-linked disaccharides 25-28 were isolated as their acetates 29-32.The previously determined crystal structure of 24 shows no intramolecular H-bonds.The yield of the glycosidation of 24, but not of 3, depends upon the concentration, indicating that activation of 24 by intermolecular H-bonds is required.Glycosidation of 2 and 3 with the trichloroacetimidate 14 gave mixtures of four (5, 6, 15, and 16), and six (7, 8, and 17-20) disaccharides, respectively (Scheme 2).

The dye-sensitized photooxygenation of 2,5-bis(glycosyl)furans followed by warming up to r.t. provides 1,1′- linked disaccharides separated by a functionalized spacer. Asymmetrical disubstituted glycosyl furans give the corresponding Bayer-Villiger type-rearranged products in a molar ratio depending on the sugars and the protecting groups. The migratory aptitudes have been rationalized by both theoretical calculations and experimental data.
