Abstract:
:A flexible, direct, high yielding synthesis of 2-alkylsulfanyl estrogens from estrone has been developed. 2-Methylsulfanyl estradiol (2-MeSE2) 7 displays a similar anti-proliferative activity to the established 2-methoxyestradiol (2-MeOE2) 1, whilst its 3-O-sulfamate derivative (2-MeSE2MATE) 9 exhibits greatly enhanced anti-proliferative activity, combined with significant inhibition of steroid sulfatase, an enzyme target for the treatment of hormone-dependent tumours.
