Synthesis and in vivo antihyperglycemic activity of 5-(1H-pyrazol-3-yl)methyl-1H-tetrazoles
摘要:
A series of 5-[(5-aryl-1H-pyrazol-3-yl)methyl]-1H-tetrazoles 3a-h have been synthesized and evaluated for their in vivo antihyperglycemic activity. Some of the synthesized compounds have shown significant glucose lowering activity in male Sprague-Dawley rats in sucrose loaded model. These compounds were also evaluated for their peroxisome proliferator activated receptor gamma agonistic property, but none of them displayed any significant activity. (c) 2005 Elsevier Ltd.

6-Aryl-4-methylsulfanyl-2H-pyran-2-one-3-carbonitriles as PPAR-γ activators
摘要:
Various 6-aryl-3-cyano/methoxycarbonyl-4-methylsulfanyl-2H-pyran-2-ones have been synthesized as a potential substitute of 2,4-thiazolidinedione head group to express potent PPAR-gamma transactivation response. Some of the screened compounds have shown promising PPAR-gamma agonistic activity. (c) 2005 Elsevier Ltd. All rights reserved.
