  Synthesis and structure–activity relationships of andrographolide analogues as novel cytotoxic agents

  摘要：

  Andrographolide 1, the cytotoxic agent of the plant Androgrophis paniculata was subjected to semi-synthetic studies leading to the preparation of a number of potent and novel analogues. Of the analogues synthesized, while 8,17-epoxy andrographolide 6 retained the cytotoxic activity of 1, ester derivatives of 6 exhibited considerable improvement in activity. Lower activity was observed when the epoxy moiety in the triacetate 9, derived from 6 was modified. Synthesis and structure-activity relationships are discussed. (C) 2004 Elsevier Ltd.
