N-Acetyl glucosamine and chitooligosaccharides are selectively converted into beta-glycosides without protection of the other hydroxyl groups by alkylation of the anomeric alkoxides in N,N-dimethylformamide containing lithium bromide. Addition of the lithium salt notably improves the stereoselectivity of the glycosylation of the monomer and the efficiency of the process with higher oligomers.

The lantibiotic mersacidin exerts its bactericidal action by inhibition of peptidoglycan biosynthesis. It interferes with the membrane-associated transglycosylation reaction; during this step the ultimate monomeric peptidoglycan precursor, undecaprenyl-pyrophosphoryl-MurNAc-(pentapeptide)- GlcNAc (lipid II) is converted into polymeric nascent peptidoglycan. In the present study we demonstrate that the molecular basis of this inhibition is the interaction of mersacidin with lipid II. The adsorption of [14C]mersacidin to growing cells, as well as to isolated membranes capable of in vitro peptidoglycan synthesis, was strictly dependent on the availability of lipid II, and antibiotic inhibitors of lipid II formation strongly interfered with this binding. Direct evidence for the interaction was provided by studies with isolated lipid II. [14C]mersacidin associated tightly with [14C]lipid II micelles; the complex was stable even in the presence of 1% sodium dodecyl sulfate. Furthermore, the addition of isolated lipid II to the culture broth efficiently antagonized the bactericidal activity of mersacidin. In contrast to the glycopeptide antibiotics, complex formation does not involve the C-terminal D-alanyl-D-alanine moiety of the lipid intermediate. Thus, the interaction of mersacidin with lipid II apparently occurs via a binding site which is not targeted by any antibiotic currently in use.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 14215-68-0, help many people in the next few years., Reference of 14215-68-0

CYP1B1 is recognized as a new target in cancer prevention and therapy. Taking alpha-naphthoflavone as a lead, a series of 6,7,10-trimethoxy-alpha-naphthoflavones (4a-o) were synthesized and evaluated for their inhibitory potency against CYP1B1 and selectivity over CYP1A1 and 1A2. SAR analysis indicated that introducing methoxy groups at C(6), C(7), and C(10) on the naphthalene part and a fluoro atom at C(3?) on the B-ring, could sharply increase the efficiency toward CYP1B1 inhibition. Among the prepared derivatives, compound 4c is the most potent and selective CYP1B1 inhibitor ever reported. More effort was taken to acquire water-soluble alpha-naphthoflavone derivatives for further cell-based study of overcoming anticancer drug-resistance. Finally, we obtained water-soluble naphthoflavone (11f) which could obviously eliminate the docetaxel-resistance caused by the enhanced expression of CYP1B1 in MCF-7/1B1 cells. It could be envisaged that the discovery of new alpha-naphthoflavones as CYP1B1 inhibitors is clinically important for overcoming CYP1B1-mediated drug-resistance in cancer therapeutics.

D-Glucosamine was successfully employed as a chiral auxiliary for the enantioselective synthesis of phosphine oxides. The influence of the anomeric position was also investigated and revealed the excellent ability of the alpha-anomer to perform this transformation in a highly selective fashion. The methodology employed consisted of three steps: diastereoselective formation of the oxazaphospholidine followed by subsequent selective cleavage of P-N and P-O bonds by reaction with two Grignard reagents. P-epimers oxazaphospholidines were prepared switching from a P(V) to a P(III) precursor, thus allowing for the synthesis of enantiomeric phosphine oxides. In addition, the chiral auxiliary could be recovered and efficiently recycled.

The ready construction of 24 stereochemically and functionally diverse carbohydrate ligand structures from a core D-glucosamine scaffold has allowed the evaluation of broad ranging structure activity relationships in ligand accelerated zincate additions to aldehydes, with variations in deltadeltaG+/+(R-S) of up to 5650 J mol(-1) that create opposing senses of asymmetric induction and that are consistent with models based on several ligand X-ray structures and molecular mechanics analysis. Factorial analysis of enantioselectivity using key dihedral angles and steric volume on N-2 also highlight the potential for the use of factorial design in ligand construction.

Sialyl Lewis x and derivatives have been synthesized using 0-1,4-galactosyltransferase and recombinant alpha-2,3-sialyltransferase and alpha-l,3-fucosyltransferase. The enzymatic glycosylations have been achieved on preparative scales with in situ regeneration of UDP-galactose, CMP-N-acetylneuraminic acid, and GDP-fucose. Additionally, galactosyltransferase and fucosyltransferases have been studied with respect to their substrate specificity and inhibition. The enzymatic procedures have also been used in the synthesis of 2?-deoxy-LacNAc, 2?-amino-2?-deoxy-LacNAc, 2-azido-Lac, Lewis x, the Lewis x analog with GlcNAc replaced with 5-thioglucose, [Gal-l-13C]-LacNAc, [Gal-1-13C]-sialyl Lewis x, and the corresponding terminal glycal. The synthesized 13C-labeled sialyl Lewis x and intermediates (including Lewis x and sialyl LacNAc) were used for conformational study using NMR techniques combined with calculations based on GESA and MM2 programs. GESA calculation of sialyl Lewis x gave four minimum-energy conformers, and the two (A and B) consistent with NMR results were further refined with MM2 calculation. The one (A’) with lower energy was picked as the preferred conformer which had all internuclear distances and glycosidic torsional angles consistent with the NMR analysis. The glycosidic torsional angle psi of Gal-GlcNAc, for example, was determined to be 18 on the basis of the coupling between Gal-1-13C and GlcNAc, while the predicted value was 15. The tetrasaccharide appears to form a well-defined hydrophilic surface along NeuAc-Gal- Fuc, and a hydrophobic face underneath NeuAc-Gal-GlcNAc. Comparing the conformation of sialyl Lewis x to sialyl Lewis a indicates that the recognition domain of sialyl Lewis x mainly comes from the sialic acid – galactose – fucose residues.
