Protein tyrosine phosphatase 113 (PTP-1B) is an enzyme that plays a critical role in down-regulating insulin signaling through dephosphorylation of the insulin receptor. Studies have shown that PTP-1B knockout mice showed increased insulin sensitivity in muscle and liver as well as resistance to obesity. A series of hydroxy benzofuran methyl ketones and their naturally mimicking dimers and linear and angular furanochalcones and flavones have been evaluated as PTP-1B inhibitors. Screened compounds displayed good inhibitory activity. (c) 2006 Elsevier Ltd. All rights reserved.

A Controlled Synthesis of Nature-Mimicking Benzofurans and their Corresponding Dimers
Benzofurans functionalized with hydroxy and acetyl functionalities are not only the core structures found in a large number of biologically important natural products, but also the vital precursors for several naturally occurring furanoflavonoids. Numerous synthetic methodologies are available in the literature for the synthesis of functionalized benzofurans but access to benzofurans with adjacent hydroxy and acetyl functionalities shows paucity of references. In this paper we report highly convenient synthesis of nature-mimicking benzofurans and their dimers from easily accessible precursors.
