  Stereochemical probes for the estrogen receptor: Synthesis and receptor binding of (17α,20EZ)-21-phenyl-19-norpregna-1,3,5(10), 20-tetraene-3,17β-diols

  摘要：

  Previous studies from our laboratory using 17 alpha-E- and 17 alpha-Z-halovinyl and phenylthiovinyl estradiols demonstrated a marked preference for the Z stereochemistry and a significant steric tolerance for the Z-vinyl substituent. To further explore the extent of that stereochemical preference and steric tolerance we have prepared stereoselectively the 17 alpha-E- and 17 alpha-Z-phenylvinyl estradiols (E- and Z-styrylestradiols). The results, in addition to demonstrating a facile preparation of the target compounds, supported the previously observed stereochemical and steric effects. The relative binding affinities for the Z isomer were 3-4-fold greater than the E isomer at both 4 degrees C and 25 degrees C, and only one-half to one-fourth those of estradiol under similar conditions. The developing model for ligand-accessible space within the estrogen receptor suggests that Z-phenylvinyl estradiols may provide interesting and useful probes for mapping the receptor.

  用于开发荧光雌激素受体配体的 17α -雌二醇的取代类似物

  摘要：

  为了成功开发出高亲和力荧光团-雌二醇偶联物，荧光团必须连接到雌二醇分子上对其与受体结合干扰最小的位置。基于文献先例和我们早期使用小 17 α 侧链的工作，我们专注于 17 α 取代基作为荧光团连接的模型。在本报告中，我们描述了 19 种雌二醇类似物的合成和雌激素受体结合亲和力，它们在 17 α 位取代了较大的侧链（6 到 11 个碳），其中一些可能经过合成修饰以连接荧光团。这些类似物是通过雌酮-17 β-环氧乙烷 3-苄基醚的亲核裂解和随后的脱苄基（4 到 18），通过炔烃（21 到 24）的交叉偶联合成的，通过 17 α-乙炔雌二醇 3,17-双（四氢吡喃基醚）的烷基化和随后的酸性水解（25 至 28），或通过将雌酮与适当的芳基/炔基锂试剂（29、30 和 32）或与苄基溴化镁（ 31)。使用标准竞争测定法测定这些新合成的类似物对雌激素受体（大鼠子宫）的相对结合亲和力。结果表明，侧链中迁

  The nickel-catalyzed synthesis of tetrasubstituted cyclobutenes from alkynes is reported. This transformation is uniquely promoted by the use of a primary aminophosphine, an unusual ligand in nickel catalysis. Mechanistic insights for this new transformation are provided, and postreaction modifications of the cyclobutene products to stereodefined cyclic and acyclic compounds are reported, including

  inhibit steroid sulfatase activity may be a rewarding approach to the treatment of androgeno-sensitive and estrogeno-sensitive diseases. In the present study, we report the chemical synthesis and biological evaluation of a new family of steroid sulfatase inhibitors. The inhibitors were designed by adding an alkyl, a phenyl, a benzyl, or a benzyl substituted at position 17alpha of estradiol (E(2)), a C18-steroid

• Syntheses and affinities of novel organometallic-labeled estradiol derivatives: a structure-affinity relationship

  Two series of novel estradiol derivatives, including cationic species, labeled with organometallic fragments Cr(CO)3, Cp*Ru+, or Cp*Rh2+ [Cp* = eta-5-C5(CH3)5] either in the 17-alpha-position or on the A-ring were synthesized, and their relative binding affinities (RBA) for the estradiol receptor were determined. The Ru(II) and the Rh(III) cationic derivatives were obtained as stable salts with the following counter anions (BF4-, PF6-, CF3SO3-). The satisfactory RBA values obtained for most complexes belonging to the 17-alpha series confirm that this position tolerates the presence of bulky neutral species. For instance, complex 4, in which the organometallic fragment Cr(CO)3 Was attached to the phenyl ring of the 17-alpha-phenylethynyl fragment, exhibited an RBA value of 24%, very similar to that of the uncomplexed estrogen derivative 3. Surprisingly, the analogous cationic species 6 had no affinity for the estradiol receptor. This unprecedented result shows that the hormone binding site of the estrogen receptor does not tolerate the presence of a positive charge in the 17-alpha-position of the steroid. On the other hand, the alpha-face of the A-ring of estradiol did tolerate positively charged organometallic fragments bearing bulky substituents althoug the RBA value tended to decrease with increasing charge. The counterion in these cationic derivatives also affected binding affinity. For instance, the Ru(II) species 7a containing an CF3SO3- ion exhibited a reasonable RBA value (5.8%) compared to analogous species 13 with a PF6- ion (RBA of only 0.1%). Moreover, the triflate counteranion preserved the phenolic form of the A-ring of the estrogen derivative whereas the PF6- derivative was unstable and rapidly converted into the dienonylic form in buffer. The compared RBAs of the neutral and cationic species illustrate the preferences of the receptor hormone binding site in accepting or rejecting species of hydrophobic or hydrophilic character.
