  N-butyl, N-methyl, 11-[3′,17′ β-(dihydroxy)-1′,3′,5′(10′)- estratrien-16′ α-yl]-9(R/S)-bromo undecanamide: synthesis and 17β-HSD inhibiting, estrogenic and antiestrogenic activities

  摘要：

  The synthesis of a 16 alpha-(bromoalkylamide) derivative of estradiol (N-butyl, N-methyl, 11-[3',17'beta-(dihydroxy)-1',3',5'(10')-estratrien-16'alpha-yl]-9(R/S)-bromo undecanamide) was performed by two different approaches starting from estrone. Each approach hers the same key intermediate, containing an aldehyde group, but differs by the bromination step and the timing of formation of the amide group. This compound was found to cause, at 100 mu M, a complete inhibition of 17 beta-hydroxysteroid dehydrogenase (17 beta-HSD) responsible for the interconversion of estrone and estradiol. The corresponding IC50 value was 10.6 mu M. In the estrogen-sensitive ZR-75-1 human breast cancer cell line, this estradiol derivative has no estrogenic activity at 30 nM and only a minimal estrogenic activity (10% above the basal level) at 1 mu M. At this latter concentration, this compound causes a 28% inhibition of 0.1 nM EI-induced cel[proliferation (antiestrogenic activity). Thus, the introduction of a side-chain with a secondary bromide and a butyl methyl amide group at the 16 alpha-position of estradiol has two interesting effects; namely an inhibition of cytosolic 17 beta-HSD and a blockade of the estrogenic effect of estradiol.

• Synthesis of a First Estradiol-Adenosine Hybrid Compound

  An estradiol derivative, bearing an adenosine residue linked at C-16alpha by a three-carbon side chain, provides access to a new series of substrate-cofactor hybrid compound designed to potentially interact with two binding domains of the enzyme type 1 17alpha-hydroxysteroid dehydrogenase (17beta-HSD). The synthesis of 5'-O-[3-(3',17'beta-dihydroxy-1',3',5'(10')-estratrien-16'alpha-yl)propanoyl]adenosine (7) is reported focusing on the crucial last steps: the coupling of adenosine residue to estradiol side chain by an ester link and the appropriate final cleavage of three protecting groups.
