  Synthesis of 4-Formyl Estrone Using a Positional Protecting Group and Its Conversion to Other C-4-Substituted Estrogens

  摘要：

  [GRAPHICS]4-Formyl estrone was synthesized in overall good yield in three steps starting from estrone. This was achieved by conducting an electrophilic aromatic substitution reaction using formaldehyde, triethylamine, and MgCl2 on 2-tert-butyl estrone, which was readily prepared in 96% yield from estrone using tertbutyl alcohol and BF3OEt2. The tert-butyl group acted as a positional protecting group to prevent reaction at the 2-position. The tert-butyl group was readily removed in good yield using AlCl3 in dichloromethane/CH3NO2. To our knowledge, this represents the first use of a positional protecting group for the synthesis of a C-4-modified estrogen. 4-Formyl estrone was used as a common precursor to obtain a variety of other C-4 modified estrogens in very high yields such as 4-methylestrone and 4-hydroxymethylestrone as well as the novel estrogen 4-carboxyestrone. The syntheses of 4-formyl, -methyl-, and -hydroxymethyl estrone represent dramatic improvements over previously reported syntheses of these compounds.

  Steroidal oxathiazine inhibitors of estrone sulfatase

  摘要：

  The presence of estrone sulfatase in breast tumors and the high levels of circulating estrone sulfate may contribute the major portion of estrogen synthesized locally in breast tissues through conversion of estrone sulfate to estrone by the enzyme. Using inhibitors of estrone sulfatase for the treatment of estrogen-dependent (estrogen receptor positive, ER+) breast cancer could be a very effective therapeutic strategy for the treatment of estrogen-dependent breast tumors in postmenopausal women. Therefore, we designed and synthesized several steroidal 2',3-oxathiazines that inhibit estrone sulfatase and have greatly reduced estrogenic side effects. Our in vitro studies indicate that the oxathiazine compounds have inhibitory activity on estrone sulfatase in MCF-7 human breast cancer cells. These estrone sulfatase inhibitors (ESIs) also inhibit the growth of MCF-7 cells induced by estrone sulfate. In addition, our in vivo experiments demonstrate that our ESIs have moderate antitumor activity against MCF-7 breast cancer xenografts in Balb/c athymic nude mice. The synthesis and biological activity of a number of these unique steroidal ESIs are described. (C) 2002 Elsevier Science Inc. All rights reserved.

  Several estrogens were mono-formylated using a mixture of paraformaldehyde. MgCl2, and Et3N in refluxing THF. In all cases, the 2-isomer was formed as the major product with high regioselectivity compared to the 4-isomer. Excellent to high yields were obtained in all examples except one. The method was applied for an efficient synthesis of the anti-cancer agent 2-methoxyestradiol. (C) 2011 Elsevier Ltd. All rights reserved.

  [GRAPHICS]The 2,2,2-trichloroethyl (TCE) group was utilized as the first protecting group for aryl sulfates. Aryl sulfates, protected with the TCE group, were prepared in high yield by reacting phenols with chlorosulfuric acid TCE ester. Deprotection was accomplished using Pd/C-ammonium formate or with Zn-ammonium formate to give aryl sulfate monoesters in high yield. This approach to aryl sulfate synthesis was successfully applied to the construction of estrone sulfate derivatives, which could not be prepared by previous methodologies.
• Inhibition of steroid sulfatase with 4-substituted estrone and estradiol derivatives

  Steroid sulfatase (STS) catalyzes the desulfation of biologically inactive sulfated steroids to yield biologically active desulfated steroids and is currently being examined as a target for therapeutic intervention for the treatment of breast cancer. We previously demonstrated that 4-formyl estrone is a time- and concentration-dependent inhibitor of STS. We have prepared a series of 4-formylated estrogens and examined them as irreversible STS inhibitors. Introducing a formyl, bromo or nitro group at the 2-position of 4-formylestrone resulted in loss of concentration and time-dependent inhibition and a considerable decrease in binding affinity. An estradiol derivative bearing a formyl group at the 4-position and a benzyl group at the 17 beta-position yielded a potent concentration and time-dependent STS inhibitor with a K-l of 85 nM and a k(inact) of 0.021 min(-1) (k(inact)/K-l of 2.3 x 10(5) M-1 min(-1)). Studies with estrone or estradiol substituted at the 4-position with groups other than a formyl group revealed that good reversible inhibitors can be obtained by introducing small electron withdrawing groups at this position. An estradiol derivative with fluorine at the 4-position and a benzyl group at the 17 beta-position yielded a potent, reversible inhibitor of STS with an IC50 of 40 nM. The introduction of relatively small electron withdrawing groups at the 4-position of estrogens and their derivatives may prove to be a general approach to enhancing the potency of estrogen-derived STS inhibitors.
