Azetidinyl oxadiazoles as potent mGluR5 positive allosteric modulators

A novel series of aryl azetidinyl oxadiazoles are identified as mGluR5 positive allosteric modulators (PAMs) with improved physico-chemical properties. N-substituted cyclohexyl and exo-norbornyl carboxamides, and carbamate analogs of azetidines are moderate to potent mGluR5 PAMs. The aryl, lower alkyl carboxamides analogs and sulfonamide analogs of azetidines are moderate mGluR5 negative allosteric modulators (NAMs). In the aryl oxadiazole moiety, substituents such as fluoro, chloro and methyl are well tolerated at the meta position while para substituents led to either inactive compounds or NAMs. A tight pharmacophore and subtle ‘PAM to NAM switching’ with close analogs makes the optimization of the series extremely challenging.

THE USE OF N-ARYL DIAZASPIRACYCLIC COMPOUNDS IN THE TREATMENT OF ADDICTION

Compounds, compositions and methods for treating drug addiction, nicotine addiction, and/or obesity are disclosed. The compounds are N-aryl diazaspirocyclic compounds, bridged analogs of N-heteraryl diazaspirocyclic compounds, or prodrugs or metabolites of these compounds. The aryl group can be a five- or six-membered heterocyclic ring (heteroaryl). The compounds are effective at inhibiting dopamine production and/or secretion, and accordingly are effective at inhibiting the physiological “”reward”” process that is associated with ingestion of nicotine and/or illicit drugs. The compounds and compositions can be administered in effective amounts to inhibit dopamine release, wihout resulting in appreciable adverse side effects (e.g., side effects such as significant increases in blood pressure and heart rate, significant negative effects upon the gastro-intestinal tract, and significant effects upon skeletal muscle).

Pd/C-catalyzed reactions of HMF: Decarbonylation, hydrogenation, and hydrogenolysis

The diverse reactivity of 5-hydroxymethylfural (HMF) in Pd/C-catalyzed reactions is described with emphasis on the role of additives that affect selectivity. Three broad reactions are examined: decarbonylation, hydrogenation, and hydrogenolysis. Especially striking are the multiple roles of formic acid in hydrogenolysis/hydrogenation and in suppressing decarbonylation, as illustrated by the conversion of HMF to DMF. Hydrogenation of the furan ring is suppressed by CO2 and carboxylic acids. These results emphasize the utility of Pd/C as a convenient catalyst for upgradation of cellulosic biomass.
