Novel inhibitors of Ras protein activation have been found, containing a bicyclic core derived from D-arabinose and benzyl and phenylhydroxylamine moieties. NMR studies (trNOE, saturation-transfer difference, STD) of the binding between these molecules and human p21 h-Ras are reported. A pharmacophore mapping indicates that both the benzyl and the phenylhydroxylamine moieties are essential for protein binding. Molecules lacking one of these groups were synthesized and tested to confirm this hypothesis, and no interaction with Ras in vitro, nor biological activity in mammalian cells was observed. Our studies led to the development of molecules that selectively inhibit Ras-dependent cellular growth in mammalian cells. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.

Electric Literature of 125995-03-1, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 125995-03-1, Name is Atorvastatin lactone, molecular formula is C33H33FN2O4. In a Article£¬once mentioned of 125995-03-1

The drug?drug interaction profile of atorvastatin confirms that disposition is determined by cytochrome P450 (CYP) 3A4 and organic anion transporting polypeptides (OATPs). Drugs that affect gastric emptying, including dulaglutide, also affect atorvastatin pharmacokinetics (PK). Atorvastatin is a carboxylic acid that exists in equilibrium with a lactone form in vivo. The purpose of this work was to assess gastric acid?mediated lactone equilibration of atorvastatin and incorporate this into a physiologically-based PK (PBPK) model to describe atorvastatin acid, lactone, and their major metabolites. In vitro acid-to-lactone conversion was assessed in simulated gastric fluid and included in the model. The PBPK model was verified with in vivo data including CYP3A4 and OATP inhibition studies. Altering the gastric acid?lactone equilibrium reproduced the change in atorvastatin PK observed with dulaglutide. The model emphasizes the need to include gastric acid?lactone conversion and all major atorvastatin-related species for the prediction of atorvastatin PK.

The copper(II) complex of the deprotonated form of di-2-pyridylamine has been prepared by treating the ligand with freshly prepared copper(II) hydroxide, and the crystal structure determined.Crystal data: Monoclinic, space group C2/c, a=14.691(6), b=12.256(9), c=11.945(2) Angstroem, beta=124.24(3) deg, and Z=4.The final R value was 0.039 for 1 052 independent, observed reflections.The copper atom environment is pseudo-tetrahedral with a dihedral angle of 58.8 deg between the two CuN2 ligand planes.It is demonstrated that the observed molecular structure and the ligand field spectra in the literature are in good agreement.The extent of distortion from pure tetrahedral geometry in a series of related copper bis(bidentate ligand) complexes, as estimated from ligand-field spectra, correlates very well with the observed crystallographic dihedral angle values.This structural result is now available for calibration of the electronic and e.s.r. spectral data for small-molecule pseudo-tetrahedral copper(II) complexes and the presumed four-co-ordinated Type I ‘blue’ copper protein sites.

The numerous biological roles of LacNAc-based oligosaccharides have led to an increased demand for these structures for biological studies. In this report, an efficient route for the synthesis of beta-galactosides using a bacterial beta-4-galactosyltransferase/-UDP-4?-gal-epimerase fusion protein is described. The lgtB gene from Neisseria meningitidis and the galE gene from Streptococcus thermophilus were fused and cloned into an expression vector pCW. The fusion protein transfers galactose to a variety of different glucose- and glucosamine-containing acceptors, and utilizes either UDP-galactose or UDP-glucose as donor substrates. A crude lysate from Escherichia coli expressing the fusion protein is demonstrated to be sufficient for the efficient preparation of galactosylated oligosaccharides from inexpensive UDP-glucose in a multigram scale. Lysates containing the fusion protein are also found to be useful in the production of more complex oligosaccharides in coupled reaction mixtures, e.g., in the preparation of sialosides from N-acetylglucosamine. Thus, bacterially expressed fusion protein is well suited for the facile and economic preparation of natural oligosaccharides and synthetic derivatives based on the lactosamine core.
