11beta-Hydroxysteroid dehydrogenase type 1 (11beta-HSD1) has been widely considered by the pharmaceutical industry as a target to treat metabolic syndrome in type II diabetics. We hypothesized that central nervous system (CNS) penetration might be required to see efficacy. Starting from a previously reported pyrimidine compound, we removed hydrogen-bond donors to yield 3, which had modest CNS penetration. More significant progress was achieved by changing the core to give 40, which combines good potency and CNS penetration. Compound 40 was dosed to diet-induced obese (DIO) mice and gave excellent target engagement in the liver and high free exposures of drug, both peripherally and in the CNS. However, no body weight reduction or effects on glucose or insulin were observed in this model. Similar data were obtained with a structurally diverse thiazole compound 51. This work casts doubt on the hypothesis that localized tissue modulation of 11beta-HSD1 activity alleviates metabolic syndrome.

name: (Tetrahydrofuran-3-yl)methanol, Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes.

A variable-temperature 13C NMR study, accompanied by a high-resolution 1H NMR conformational analysis study, on a series of monocyclic oxyphosphoranes is reported.The selected compounds enabled us to study the acceleration of the rates of intramolecular ligand reorganization on pentacoordinated phosphorus.It allowed us to determine whether the enhancement of the reorganization rates was brought about by accelerated pseudorotation due to the conformational transmission effect or by the involvement of hexacoordinated zwitterionic phosphorus intermediates.The results of the study further substantiate the findings that the involvement of such hexacoordinated intermediates is of no importance in the type of oxyphosphoranes studied.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 1679-47-6, name is 3-Methyldihydrofuran-2(3H)-one, introducing its new discovery. HPLC of Formula: C5H8O2

Each of a series of C5H8O2 isomeric carboxylic acids and lactones (1-9) was protonated in both concentrated sulfuric acid and trifluoromethanesulfonic acid.The thermally induced transformations of the protonated species were then studied over the temperature range -40 to +160 deg C.As a general rule, all the initially generated cations were eventually converted to protonated gamma-valerolactone (1HO+) and, finally, to protonated cyclopentenone (10HO+).The cations derived from the cyclopropanecarboxylic acids 7 and 8 both underwent ring opening to the unsaturated cation 6HO+, which then rearranged to a protonated alpha-lactone.In concentrated sulfuric acid the latter species loses carbon monoxide to afford protonated 2-butanone 11HO+.The CIMS spectra of compounds 1-9 were recorded, allowing a correlation between the fragmentation routes in the gas phase and the transformations observed in solution.In this way, the data obtained in strong acids are used to assign reasonable structures to the gas-phase ions.
