Direct dehydrative glycosylation catalyzed by diphenylammonium triflate

Methods for direct dehydrative glycosylations of carbohydrate hemiacetals catalyzed by diphenylammonium triflate under microwave irradiation are described. Both armed and disarmed glycosyl-C1-hemiacetal donors were efficiently glycosylated in moderate to excellent yields without the need for any drying agents and stoichiometric additives. This method has been successfully applied to a solid-phase glycosylation.

Outer-sphere coordination, N-coordination and O-coordination of the deprotonated saccharin in copper(II) saccharinato complexes. Implications for the saccharinato carbonyl stretching frequency

Tetraaquabis(o-sulfobenzimidato-N)copper(II) reacts with neutral N-heterocycles to form complexes in which the o-sulfobenzimide (saccharin) entity interacts directly with the copper atom (through either the endocyclic nitrogen atom or the exocyclic oxygen atom) or indirectly, through coordinated water molecules. With 4-aminopyridine, it yields diaquatetrakis(4-aminopyridine)copper(II)di(o-sulfobenzimidate)dihydrate, whose metal atom shows trans-N4O2 octahedral coordination. The o-sulfobenzimidate anions interact with the copper atom through the coordinated water molecules, and they link with the lattice water molecules to furnish three-dimensional network architecture. The reagent when treated with pyrazole affords tetrakis(pyrazole)bis[1,2-benzisothiazolyl-3-olato 1,1-dioxide]copper(II); in this neutral compound, the metal atom and the o-sulfobenzimidate moieties are linked by covalent copper-oxygen bonds. The aqua complex with di-2-pyridylamine has the copper atom in a square-pyramidal configuration: one of the o-sulfobenzimidate ligands binds through its nitrogen atom whereas the other binds through the exocyclic oxygen atom in aqua(di-2-pyridylamine)[1,2-benzisothiazolyl-3-olato 1,1-dioxide](o-sulfobenzimidato-N)copper(II), which adopts a linear hydrogen-bonded chain motif. When treated with nicotinamide, tetraaquabis(o-sulfobenzimidato-N)copper(II) affords a monohydrated di(nicotinic acid) adduct, the amide group being oxidized to a carboxylic group. In this square-pyramidal complex, the molecules are linked by hydrogen bonds involving the two carboxylic acid ends into a linear chain that propagates along the a-c diagonal of the unit cell. The coordination mode of the o-sulfobenzimidate entities in the complexes is reflected in the stretching frequencies of the carbonyl groups, the respective band(s) being blue-shifted for N-coordination and red-shifted for O-coordination relatively to the o-sulfobenzimidate ions, leading to the frequency order N-coordinated > uncoordinated > O-coordinated. These shifts should be considered in vibrational frequency versus bond order correlations.

Prodrugs for colon-restricted delivery: Design, synthesis, and in vivo evaluation of colony stimulating factor 1 receptor (CSF1R) inhibitors

The ability to restrict low molecular weight compounds to the gastrointestinal (GI) tract may enable an enhanced therapeutic index for molecular targets known to be associated with systemic toxicity. Using a triazolopyrazine CSF1R inhibitor scaffold, a broad range of prodrugs were synthesized and evaluated for enhanced delivery to the colon in mice. Subsequently, the preferred cyclodextrin prodrug moiety was appended to a number of CSF1R inhibitory active parent molecules, enabling GI-restricted delivery. Evaluation of a cyclodextrin prodrug in a dextran sodium sulfate (DSS)-induced mouse colitis model resulted in enhanced GI tissue levels of active parent. At a dose where no significant depletion of systemic monocytes were detected, the degree of pharmacodynamic effect?measured as reduction in macrophages in the colon?was inferior to that observed with a systemically available positive control. This suggests that a suitable therapeutic index cannot be achieved with CSF1R inhibition by using GI-restricted delivery in mice. However, these efforts provide a comprehensive frame-work in which to pursue additional gut-restricted delivery strategies for future GI targets.

The GlyT1 transporter has emerged as a key novel target for the treatment of schizophrenia. Herein, we report on the optimization of the 2-alkoxy-5-methylsulfonebenzoylpiperazine class of GlyT1 inhibitors to improve hERG channel selectivity and brain penetration. This effort culminated in the discovery of compound 10a (RG1678), the first potent and selective GlyT1 inhibitor to have a beneficial effect in schizophrenic patients in a phase II clinical trial.
