Synthesis and pharmacological evaluation of prenylated and benzylated pterocarpans against snake venom

Bioorg Med Chem Lett. 2004 Jan 19;14(2):431-5. doi: 10.1016/j.bmcl.2003.10.044.

Abstract

Edunol (3), a pterocarpan isolated from Harpalyce brasiliana, a plant used in the northeast of Brazil against snakebites, was obtained by synthesis and showed antimyotoxic, antiproteolytic and PLA2 inhibitor properties. These proprieties could be improved through the synthesis of a bioisoster (5), where the prenyl group was replaced by the benzyl group.
