in ethanol at room temperature yielded the corresponding 5-(1-adamantyl)-3-arylaminomethyl-1,3,4-oxadiazoline-2-thiones 4a-m or 5-(1-adamantyl)-3-(4-substituted-1-piperazinylmethyl)-1,3,4-oxadiazoline-2-thione s 5a-h, respectively. All the synthesized compounds were tested for in vitro activities against certain strains of Gram-positive and Gram-negative bacteria and the yeast-like pathogenic fungus

Compounds having Formula (I), including pharmaceutically acceptable salts and prodrugs thereof: are selective inhibitors of the 11β-HSD1 enzyme. They inhibit the 11β-HSD1-mediated conversion of cortisone and other 11-keto-glucocorticoids to cortisol and other 11β-hydroxy-glucocorticoids. The 11β-HSD1 inhibitors therefore decrease the amount of cortisol in target tissues, thereby modulating the effects of cortisol. Modulation of cortisol may be effective in controlling non-insulin-dependent diabetes (NIDDM), hyperglycemia, obesity, insulin resistance, dyslipidemia, hyperlipidemia, hypertension, Syndrome X, and other symptoms associated with NIDDM or with excess cortisol in the body.
acylhydrazides as alkylatingagents has been demonstrated in the copper-catalyzed tandem alkylation/cyclization of N-arylacrylamides. A range of aliphatic acylhydrazides smoothly participated in the oxidative 5-exo-trig cyclization of N-arylacrylamides with CuCO3 as the catalyst and DTBP as the oxidant, delivering structurally diverse 3,3-dialkyloxindoles in moderate to good yields. This study paves the way

Adamantyl triazoles were identified as selective inhibitors of 11 beta-hydroxysteroid dehydrogenase type 1 (11 beta-HSD1). They are active both in in vitro and in in vivo pharmacodynamic models. The synthesis and structure-activity relationships of these inhibitors are presented. (c) 2005 Elsevier Ltd. All rights reserved.
