A novel series of trans-1,3-cyclohexyl diamides was discovered and characterized as mGluR5 negative allosteric modulators (NAMs) lacking an alkyne moiety. Conformational constraint of one of the amide bonds in the diamide template led to a spirooxazoline template. A representative compound (24d) showed good in vitro potency, high CNS penetration and, upon subcutaneous dosing, demonstrated efficacy in the mouse marble burying test, generally used as indicative of potential anxiolytic activity. 相似文献

1. Plasma levels of beta-hydroxybutyrate (BHB), and acetoacetate (AcAc) have been measured in camels (Camelus dromedarius) and sheep (Ovis aries). The activity of beta-hydroxybutyrate dehydrogenase (BHB-deH2) (E.C. 1.1.1.30) was studied in the rumen epithelium and the liver of these animals. 2. Concentrations of plasma BHB and AcAc in the camel were in respective order 33 and 4 times lower than that of the sheep. The ratios of BHB to AcAc were 0.61 and 4.8 for the camel and sheep, respectively. 3. The activity of BHB-deH2 in the rumen epithelium of the camel and sheep were 7.15 and 66 mumol/hr/g wet wt tissue, respectively. The activity in both species was higher in the rumen epithelium than in the liver. 相似文献
