A series of 17β-amide-2-methoxyestradiol compounds were synthesized with an aim to enhance the antiproliferative effect of 2-methoxyestradiol. The antiproliferative activity of 2-methoxyestradiol analogs against human cancer cells was investigated. 2-methoxy-3-benzyloxy-17β-chloroacetamide-1,3,5(10)-triene (5e) and 2-methoxy-3-hydroxy-17β-butyramide-1,3,5(10)-triene (6c) had comparable or better antitumor activity than 2-methoxyestradiol. The elimination half-life of 6c (t1/2β = 240.93 min) is ten times longer than 2-ME and the area under the curve was seven times (AUC0-tmin = 2068.20 ± 315.74 μg mL?1 min) higher than 2-ME, respectively. Whereas 5e had similar pharmacokinetic behavior with 2-ME (t1/2β = 22.28 min) with a t1/2β of 29.5 min. 6c had higher blood concentration, longer actuation duration and better suppression rate against S180 mouse ascites tumor than 2-methoxyestradiol.

The 2-methoxy derivative of estradiol is currently in Phase II clinical trial as an anticancer agent while the 4-methyl derivative has been shown to interact with cytoplasmic and nuclear estrogen receptors in rat pituitary gland and hypothalamus. We hypothesize that the 16α-18F-analogs of these estrogens could be suitable radiotracers to evaluate action mechanisms of the parent compounds. In this study we report the synthesis of the 16α-18F and 16α-19F-analogs of the A-ring substituted estradiols in high yield via stereoselective opening of the intermediate 16β,17β-O-cyclic sulfones with [18F]F- or F- followed by deprotection.

A series of 16-modified 2-methoxyestradiol analogs were synthesized and evaluated for antiproliferative activity toward HUVEC and MDA-MB-231 cells, and for susceptibility to conjugation. In addition, the estrogenicity of these analogs was accessed by meas

The present invention relates to novel substituted steroid derivatives which represent selectiv inhibitors of the 17β-hydroxysteroid dehydrogenase type I (17β-HSD1) and, in addition, which may represent inhibitors of the steroid sulphatase, as well as to their salts, to pharmaceutical preparations containing these compounds and to processes for the preparation of these compounds. Furthermore, the invention concerns the therapeutic use of said novel substituted steroid derivatives, particularly their use in the treatment or prevention of steroid hormone dependent diseases or disorders, such as steroid hormone dependent diseases or disorders requiring the inhibition of 17β-hydroxysteroid dehydrogenase type I and/or steroid sulphatase enzymes and/or requiring the lowering of the endogenous 17β-estradiol concentration.

A series of new analogues of 2-methoxyestradiol (1) were synthesized to further elucidate the relationships between structure and activity. The compounds were designed to diminish the potential for metabolic deactivation at positions 2 and 17 and were analyzed as inhibitors of tubulin polymerization and for cytotoxicity. 17α-Methyl-β-estradiol (30), 2-propynyl-17α- methylestradiol (39), 2-ethoxy-17-(1′-methylene)estra-1,3,5(10)-triene-3- ol (50) and 2-ethoxy-17α-methylestradiol (51) showed similar or greater tubulin polymerization inhibition than 2-methoxyestradiol (1) and contained moieties that are expected to inhibit deactivating metabolic processes. All of the compounds tested were cytotoxic in the panel of 55 human cancer cell cultures, and generally, the derivatives that displayed the most activity against tubulin were also the most cytotoxic.

The syntheses and antimitotic activity of several novel 2-methoxyestradiol analogs are described. Structural modifications investigated include introduction of additional unsaturation in rings B and D; inversion at C-13; and substitution at the C-2, C-15, C-16, and C-7 alpha positions. Of 15 analogs synthesized, 2 have demonstrated superior biological activities compared to 2-methoxyestradiol.
