  Total Synthesis of Agosterol A: an MDR-Modulator from a Marine Sponge

  摘要：

  The first total synthesis of agosterol A, a modulator of multidrug resistance (MDR) mediated by P-gp and MRP1, and isolated from a marine sponge, was achieved from ergosterol by utilizing a regioselective epoxy-cleavage reaction and regioselective dehydroxylation as the key reactions.

  Synthesis and evaluation of 4-deacetoxyagosterol A as an MDR-modulator

  摘要：

  4-Deacetoxyagosterol A was synthesized from ergosterol by utilizing reductive regioselective epoxy cleavage as a key reaction. This synthesized congener of agosterol A, a spongean MDR-modulator, showed similar MDR-modulating activity against KB CV-60 cells overexpressing MRP. (C) 2000 Elsevier Science Ltd.
