Gram scale synthesis of the glucuronide metabolite of ABT-724

A gram scale synthesis of the glucuronide metabolite of ABT-724 is reported. Glycosidic coupling between a trichloroacetimidate glucuronyl donor and a Cbz-protected hydroxypyridylpiperazine glycosyl acceptor is the key step in the synthesis, since attempts to directly glucuronicrossed d signate the aglycon, aglycon derivatives, and other truncated glycosyl acceptors were unsuccessful. The route was used to produce 2.1 g of metabolite in eight steps from 2-chloro-5-hydroxypyridine in 21% overall yield.

Selective Production of Terminally Unsaturated Methyl Esters from Lactones Over Metal Oxide Catalysts

Metal oxide catalysts were studied for their selectivity for the production of a terminally unsaturated methyl ester, methyl 5-hexenoate (M5H), from a 6 carbon, 6-membered ring lactone, delta-hexalactone (DHL). A 15?wt% Cs/SiO2 catalyst had a selectivity of 55% to M5H. This selectivity was the highest of the metal oxide catalysts studied, which were Cs/SiO2, MgO, SrO, CeO2, ZrO2, Ta2O5, MgAl2O4, and a Mg?Zr mixed oxide. The Cs/SiO2 catalyst was utilized for the ring-opening of gamma-valerolactone (GVL), a 5 carbon, 5-membered ring lactone. The catalyst was 88% selective to the terminally unsaturated methyl ester, methyl 4-pentenoate (M4P). Weight hourly space velocity studies determined that the unsaturated ester distributions remained constant and no C=C double bond isomerization occurred. Liquid phase transesterification reactions with DHL and methanol and nuclear magnetic resonance spectroscopy confirmed that DHL undergoes ring-opening transesterification to produce an?omega-1 hydroxy methyl ester, methyl 5-hydroxyhexanoate (M5HH). Liquid phase transesterification reactions and thermochemistry calculations established that the equilibrium for GVL transesterification with methanol was favored towards the ring-closed lactone instead of the ring-opened hydroxy ester because of the decreased ring strain of GVL compared to DHL. The difference in terminally unsaturated methyl ester selectivity between GVL and DHL manifests from the difference in ring-strain energy. DHL passes through the M5HH intermediate as a result of greater ring strain, while the production of M4P from GVL most likely occurs through a direct, concerted mechanism.

Neutral discrete metal-organic cyclic architectures: Opportunities for structural features and properties in confined spaces

An emerging class of neutral metal-organic supramolecules has led to some fascinating and sophisticated structures including their photophysics and host-guest properties that have attracted the imagination of chemists. Synthetic routes including step-wise and one-step strategies have been employed to achieve the targeting of neutral structures. Several discrete neutral assemblies of various nuclearities, in which the coordination geometries for transition metals include octahedral, tetrahedral, and square planar, integrating main-group elements in supramolecular self-assembly applications allows for the formation of markedly different structural motifs. The structural characteristics of the ligands as well as the metal centers present in the neutral metallacycles allow easy tuning of their emission properties. Therefore, by engineering the different parts in neutral metal-organic ensembles, emissions from blue to red have been achieved. The neutral metallacyclic structures are unique in their well-defined forms and would be expected to function as a macrocycle host with a large internal cavity shapes generated by the tailored ligands. Hence, the presence of both photophysical properties and the cavity sizes of these neutral metallacycles make them intriguing hosts for neutral guests and metal ions. This review provides an overview of the structural features and properties of neutral discrete metal-organic cyclic architectures ranging from binuclear to fascinating multinuclear assemblies that emerged during the period from 2005 to 2012.

Critical review of statins: A bio-analytical perspective for?therapeutic?drug monitoring

Statins are amongst the most prescribed agents worldwide for treating hypercholesterolaemia. This review summarizes bio-analytical techniques for monitoring of presently available seven statins- Atorvastatin, Rosuvastatin, Pitavastatin, Simvastatin, Lovastatin, Pravastatin and Fluvastatin with a special focus on sample preparation strategies and chromatographic analysis. Applications include determination of statins in various biological fluids like plasma, serum and urine. Apart from conventional extraction procedures of Protein precipitation, Liquid?liquid extraction and Solid-phase extraction, various novel extraction techniques like Micro-extraction by packed sorbent, Dispersive liquid?liquid micro-extraction, Salting-out assisted liquid?liquid extraction etc. are also used for sample clean-up. Extracted samples are usually separated by reverse-phase HPLC and quantitated either by UV or MS/MS detection. The importance and use of chromatographic techniques to separate drug-related biotransformation products are also discussed herein. Most bio-analytical techniques allow quantitation of statins in ng/ml range making them suitable for therapeutic monitoring of statins in routine.
