Dehydrative Thioglycosylation of 1-Hydroxyl Glycosides Catalyzed by In Situ-Generated AlI3

Thioglycosylation of 1-hydroxyl glycosides catalyzed by in situ-generated AlI3 from elemental aluminium and molecular iodine has been developed. This method provides an alternative route to access anomeric thioglycosides without the use of hazard Lewis acidic activators or per-modified activated thiol sources. The major advantages of this dehydrative procedure are environmental friendly, ease of operation, high anomeric diastereoselectivity, and mild reaction conditions.

Polynuclear paddle-wheel copper(II) propionate with di-2-pyridylamine or 1,10-phenanthroline: Preparation, characterization and X-ray structure

The synthesis, spectroscopic, magnetic and structural characterization of two new polynuclear copper(II) propionate are described. Both compounds exhibit the typical paddle-wheel type structure. The complex [Cu4(dpyam)2(OCOC2H5)2(mu-O2CC2H5)6(H2O)2][Cu2(mu- O2CC2H5)4(H2O)2] ¡¤ (DMF)2 1; where dpyam = di-2-pyridylamine, the “outer” Cu ions, with a CuN2O2O? chromophore, have an intermediate five-coordinate geometry. The “inner” Cu ions, with a CuO4O? chromophore, have a square pyramidal geometry. The two Cu(II) ions in the inner unit are bridged by four syn,syn-eta1:eta1:mu propionates, showing the paddle-wheel cage type. The “outer” and “inner” linked by propionate bridges showing syn,anti-eta1:eta1:mu coordination mode. The 1D structure of complex [Cu6(phen)2(H2O)2(mu-O2CC2H5)12]n[Cu2(mu-O2CC2H5)4(H2O)2]2n ¡¤ (H2O)0.5n 2; where phen = 1,10-phenanthroline, consists of zig-zag chains of mononuclear Cu(mu-O2CC2H5)2(H2O)(phen) repeating units running along the b-axis, which are connected along the unit cell diagonal via Cu2(mu-O2CC2H5)4 paddle-wheel dinuclear units. Within mononuclear and dinuclear units, the Cu(II) ions have a square pyramidal geometry. However, the outer sphere of both compounds consists of the Cu2(mu-O2CC2H5)4(H2O)2 paddle-wheel molecule in which Cu(II) ions involve a square pyramidal geometry.

TBAF Effects 3,6-Anhydro Formation from 6-O-Tosyl Pyranosides

3,6-Anhydro sugars are common structures in algal polysaccharides and occur in the furanodictine and sauropunol natural products. We have found that treatment of 6-O-tosylpyranosides with tetrabutylammonium fluoride provides a mild, high-yielding synthesis of 3,6-anhydro sugars. Using O-glycoside substrates, 3,6-anhydropyranosides are isolated and the use of N,O-dimethyl hydroxylamine glycosides yields 3,6-anhydrofuranosides. Applying this approach, concise synthetic routes to several 3,6-anhydro sugar natural products are reported, including furanodictine A and sauropunols A-D.

Azetidine and Piperidine Carbamates as Efficient, Covalent Inhibitors of Monoacylglycerol Lipase

Monoacylglycerol lipase (MAGL) is the main enzyme responsible for degradation of the endocannabinoid 2-arachidonoylglycerol (2-AG) in the CNS. MAGL catalyzes the conversion of 2-AG to arachidonic acid (AA), a precursor to the proinflammatory eicosannoids such as prostaglandins. Herein we describe highly efficient MAGL inhibitors, identified through a parallel medicinal chemistry approach that highlighted the improved efficiency of azetidine and piperidine-derived carbamates. The discovery and optimization of 3-substituted azetidine carbamate irreversible inhibitors of MAGL were aided by the generation of inhibitor-bound MAGL crystal structures. Compound 6, a highly efficient and selective MAGL inhibitor against recombinant enzyme and in a cellular context, was tested in vivo and shown to elevate central 2-AG levels at a 10 mg/kg dose.

A Combined Chemical and Enzymatic Strategy for the Construction of Carbohydrate-Containing Antigen Core Units

Glycosidase-mediated coupling of glycal acceptors with galactose donors affords beta-1,3-linked dissacharides that are versatile intermediates for further chemical and enzymatic manipulation.The utility of these disaccharides is demonstrated by the elaboration of these compounds into type I and type IV core disaccharides of carbohydrate-containing antigens.Further conversion of the type IV dissacharide to a mucin-type trisaccharide (Galbeta1,3(GlcNAcbeta1,6)GalNAc) was accomplished with the use of a beta-1,6-N-acetylglucosaminyltransferase.This combined use of enzymatic andchemical methodologies allows for the rapid assembly, with high regio- and stereoselectivity, of core oligosaccharides of biologically important glycoconjugates.

Fragment-Based Approach to the Development of an Orally Bioavailable Lactam Inhibitor of Lipoprotein-Associated Phospholipase A2 (Lp-PLA2)

Lp-PLA2 has been explored as a target for a number of inflammation associated diseases, including cardiovascular disease and dementia. This article describes the discovery of a new fragment derived chemotype that interacts with the active site of Lp-PLA2. The starting fragment hit was discovered through an X-ray fragment screen and showed no activity in the bioassay (IC50 > 1 mM). The fragment hit was optimized using a variety of structure-based drug design techniques, including virtual screening, fragment merging, and improvement of shape complementarity. A novel series of Lp-PLA2 inhibitors was generated with low lipophilicity and a promising pharmacokinetic profile.

Discovery of a potent, selective, and orally bioavailable histamine H 3 receptor antagonist SAR110068 for the treatment of sleep-wake disorders

Previous studies have shown that compound 1 displayed high affinity towards histamine H3 receptor (H3R), (human (h-H3R), Ki = 8.6 nM, rhesus monkey (rh-H3R), Ki = 1.2 nM, and rat (r-H3R), Ki = 16.5 nM), but exhibited high affinity for hERG channel. Herein, we report the discovery of a novel, potent, and highly selective H3R antagonist/inverse agonist 5a(SS) (SAR110068) with acceptable hERG channel selectivity and desirable pharmacological and pharmacokinetic properties through lead optimization sequence. The significant awakening effects of 5a(SS) on sleep-wake cycles studied by using EEG recording in rats during their light phase support its potential therapeutic utility in human sleep-wake disorders.
