  Total synthesis of nafuredin-γ, a γ-lactone related to nafuredin with selective inhibitory activity against NADH-fumarate reductase

  摘要：

  Nafuredin-gamma (2) converted from nafuredin (1) under mild basic conditions showed the same inhibitory activity and selectivity against NADH-fumarate reductase as 1. Total synthesis of 2, a proposed active form of 1, has been accomplished by a convergent approach using Stille coupling. (C) 2003 Elsevier Ltd. All rights reserved.

  Nafuredin (1) is converted to nafuredin-gamma (2) under mild basic conditions and both compounds exhibit the same inhibitory activity and selectivity against NADH-fumarate reductase (complex 1). The total synthesis of 2 was achieved by a convergent approach using Stille coupling. The structural elements required for inhibitory activity against NADH-fumarate reductase (complex I) were then investigated by evaluation of nafuredin-gamma (2) and its structural analogues.
