Synthesis and characterization of titanium and tantalum complexes with di(2-pyridyl)amine (dpa): Molecular structures of Cp*TaCl3(dpa) and Ti(NMe2)2(dpa)2

The new titanium complex Cp*TiMe2(dpa) (1) (Cp* = eta5-C5Me5; dpa = di(2-pyridyl)amide) has been synthesized by reaction of Cp*TiMe3 with Hdpa. Reaction of Cp*TiCl3 or Cp*TaCl4 with Lidpa renders Cp*TiCl2(dpa) (2) or Cp*TaCl3(dpa) (3), respectively. On the other hand, Ti(NMe2)4 reacts with Hdpa to yield Ti(NMe2)2(dpa)2 (4). The molecular structures of 3 and 4 have been established by X-ray diffraction methods.

The mechanism of 2-furaldehyde formation from d-xylose dehydration in the gas phase. A tandem mass spectrometric study

The mechanism of reactions occurring in solution can be investigated also in the gas phase by suited mass spectrometric techniques, which allow to highlight fundamental mechanistic features independent of the influence of the medium and to clarifying controversial hypotheses proposed in solution studies. In this work, we report a gas-phase study performed by electrospray triple stage quadrupole mass spectrometry (ESI-TSQ/MS) on the dehydration of d-xylose, leading mainly to the formation of 2-furaldehyde (2-FA). It is generally known in carbohydrate chemistry that the thermal acid catalyzed dehydration of pentoses leads to the formation of 2-FA, but several aspects on the solution-phase mechanism are controversial. Here, gaseous reactant ions corresponding to protonated xylose molecules obtained from ESI of a solution containing d-xylose and ammonium acetate as protonating reagent were allowed to undergo collisionally activated decomposition (CAD) into the triple stage quadrupole analyzer. The product ion mass spectra of protonated xylose are characterized by the presence of ionic intermediates arising from xylose dehydration, which were structurally characterized by their fragmentation patterns. As expected, the xylose triple dehydration leads to the formation of the ion at m/z 97, corresponding to protonated 2-FA. On the basis of mass spectrometric evidences, we demonstrated that in the gas phase, the formation of 2-FA involves protonation at the OH group bound to the C1 atom of the sugar, the first ionic intermediate being characterized by a cyclic structure. Finally, energy resolved product ion mass spectra allowed to obtain information on the energetic features of the d-xylose?2-FA conversion.

Synergistic Glycosylation as Key to the Chemical Synthesis of an Outer Core Octasaccharide of Helicobacter pylori

Helicobacter pylori, a widespread gastric bacterial pathogen that infects 90 % of the population in developing countries, causes chronic gastritis, peptic ulcers and gastric cancer. Battling H. pylori infection is a serious challenge due to the increased resistance to antibiotics and the lack of vaccines. The lipopolysaccharide covering the H. pylori cell-surface outer membrane is an attractive target for the development of a glycoconjugate vaccine. Here, we report a [3+5] convergent synthesis of an outer core octasaccharide of H. pylori employing just three orthogonally protected building blocks. A synergistic glycosylation strategy enables the creation of five pivotal 1,2-cis-alpha-glucosidic bonds consist of four types of linkages using just three monomers. This strategy can be expanded to many 1,2-cis-alpha-gluoside-containing oligosaccharides both in solution and solid phase.

Synthesis of 2,5-anhydro-(beta-D-glucopyranosyluronate)- and (alpha-L-idopyranosyluronate)-D-mannitol hexa-O-sulfonate hepta sodium salt

Glycosidation of 2,5-anhydro-1,6-di-O-benzoyl-D-mannitol with methyl(2,3,4-tri-O-acetyl-alpha-D-glucopyranosyl-1-O-trichloroacetimidate) uronate in the presence of trimethylsilyl triflate afforded the corresponding 3-O-beta-glycoside, which after deprotection was converted into its hexa-O-sulfate with DMF¡¤SO3 to give after treatment with sodium acetate and subsequent saponification of the methyl ester with sodium hydroxide the hepta sodium salt of 2,5-anhydro-3-O-(beta-D-glucopyranosyl uronate)-D-mannitol hexa-O-sulfate. Glycosidation of the same acceptor with the alpha-thiophenylglycoside of methyl 2,4-di-O-acetyl-3-O-benzyl-L-idopyranosyl uronate in the presence of NIS/TfOH afforded the corresponding 3-O-alpha-glycoside in very low yield, therefore the alpha- thiophenylglycoside of 2-O-acetyl-2,4-O-benzylidene-3-O-benzyl-L-idopyranose was used as donor. The terminal hydroxymethyl group of the obtained disaccharide was subsequently oxidised with NaOCl/TEMPO and the obtained iduronic acid derivative was converted into the hepta sodium salt of 2,5-anhydro-3-O-(- alpha-L-idopyranosyluronate)-D-mannitol hexa-O-sulfonate with DMF¡¤SO3 and subsequent treatment with sodium acetate.

Binding modes of phosphotriesterase-like lactonase complexed with delta-nonanoic lactone and paraoxon using molecular dynamics simulations

Phosphotriesterase-like lactonases (PLLs) have received much attention because of their physical and chemical properties. They may have widespread applications in various fields. For example, they show potential for quorum-sensing signaling pathways and organophosphorus (OP) detoxification in agricultural science. However, the mechanism by which PLLs hydrolyze, which involves OP compounds and lactones and a variety of distinct catalytic efficiencies, has only rarely been explored. In the present study, molecular dynamics (MD) simulations were performed to characterize and contrast the structural dynamics of DrPLL, a member of the PLL superfamily in Deinococcus radiodurans, bound to two substrates, delta-nonanoic lactone and paraoxon. It has been observed that there is a 16-fold increase in the catalytic efficiency of the two mutant strains of DrPLL (F26G/C72I) vs. the wild-type enzyme toward the hydrolysis of paraoxon, but an explanation for this behavior is currently lacking. The analysis of the molecular trajectories of DrPLL bound to delta-nonanoic lactone indicated that lactone-induced conformational changes take place in loop 8, which is near the active site. Binding to paraoxon may lead to conformational displacement of loop 1 residues, which could lead to the deformation of the active site and so trigger the entry of the paraoxon into the active site. The efficiency of the F26G/C72I mutant was increased by decreasing the displacement of loop 1 residues and increasing the flexibility of loop 8 residues. These results provide a molecular-level explanation for the experimental behavior.

Structure-activity relationship studies of G9a-like protein (GLP) inhibitors

Given the high homology between the protein lysine methyltransferases G9a-like protein (GLP) and G9a, it has been challenging to develop potent and selective inhibitors for either enzyme. Recently, we reported two quinazoline compounds, MS0124 and MS012, as GLP selective inhibitors. To further investigate the structure?activity relationships (SAR) of the quinazoline scaffold, we designed and synthesized a range of analogs bearing different 2-amino substitutions and evaluated their inhibition potencies against both GLP and G9a. These studies led to the identification of two new GLP selective inhibitors, 13 (MS3748) and 17 (MS3745), with 59- and 65-fold higher potency for GLP over G9a, which were confirmed by isothermal titration calorimetry (ITC). Crystal structures of GLP and G9a in complex with 13 and 17 provide insight into the interactions of the inhibitors with both proteins. In addition, we generated GLP selective inhibitors bearing a quinoline core instead of the quinazoline core.
