Synthesis and biological evaluation of salpichrolide analogs as antiestrogenic agents

The antiestrogenic activity of three natural salpichrolides A, G and B (1, 3 and 4) and of five synthetic analogs containing an aromatic D ring and a simplified side chain (5-9), was evaluated on MCF-7 cells. The 2,3-ene-1-keto steroids 8 and 9 were obtained from 3β-acetoxy-17(13→18)-abeo- 5αH-pregn...
