Triazole derivatives of structural formula I are selective inhibitors of the 11&bgr;-hydroxysteroid dehydrogenase-1. The compounds are useful for the treatment of diabetes, such as noninsulin-dependent diabetes (NIDDM), hyperglycemia, obesity, insulin resistance, dyslipidemia, hyperlipidemia, hypertension, Metabolic Syndrome, and other symptoms associated with NIDDM.

detail a strategy that uses a commercially available nucleophilic organic catalyst to generate acyl and carbamoyl radicals upon activation of the corresponding chlorides and anhydrides via a nucleophilic acyl substitution path. The resulting nucleophilic radicals are then intercepted by a variety of electron-poor olefins in a Giese-type addition process. The chemistry requires low-energy photons (blue

The synthesis and liquid-crystaltransitiontemperatures of forty ester derivatives of 2-fluoro-4-hydroxybenzonitrile and 3-fluoro-4-hydroxybenzonitrile are reported. The esters contain the trans-1,4-disubstituted cyclohexane or the 1,4-disubstituted bicyclo[2.2.2]octane rings (some contain an additional phenyl ring). Many of the novel F-substituted esters exhibit substantially higher nematic-isotropic
4-n-alkylphenyl 4-n-alkylbicyclo (2.2.2) octane-1-carboxylates to produce new series of low melting esters with large nematicranges. In particular, thirty 4-n-alkyl-2-fluorophenyl and thirteen 4-n-alkyl-2-chlorlorophenyl 4-n-alkylbicyclo (2.2.2)octane-1-carboxylates are reported. The effect of the various lateral substituents on the clearing points and viscosities of the esters are rationalized in terms of
YC-1and its derivatives have been demonstrated for the first time with significant effects on inhibiting LX-2 cell activation and inducing apoptosis of LX-2 cells, making them potential agents for hepatic fibrosis therapy.
