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

  摘要：

  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. (C) 2003 Elsevier Ltd. All rights reserved.
