Tetrazolyl-phenyl acetamides are active as glucokinase activators, and are able to increase insulin secretion, which makes them useful for treating type II diabetes.

The phenylacetamide 1 represents the archtypical glucokinase activator (GKA) in which only the R-isomer is active. In order to probe whether the chiral center could be replaced, we prepared a series of olefins 2 and show in the present work that these compounds represent a new class of GKAs. Surprisingly, the SAR of the new series paralleled that of the saturated derivatives with the exception that there was greater tolerance for larger alkyl and cycloalkyl groups at R-2 region in comparison to the phenylacetamides. In normal Wistar rats, the 2,3-disubstituted acrylamide analog 10 was well absorbed and demonstrated robust glucose lowering effects. (C) 2010 Elsevier Ltd. All rights reserved.
