                                    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.
