    摘要:
    我们已经开发了两个新颖的四取代的吡唑系列,体现了1,3-二芳基-4,5-二烷基或3,5-二芳基-1,4-二烷基取代的模式。我们先前开发的区域选择性方法的范围得以扩展,可以直接从α,β-不饱和酮合成第一系列的这些四取代的吡唑。这些吡唑中的一些对雌激素受体(ER)亚型ERalpha和ERbeta的结合亲和力非常高,总体亲和力模式表明三个酚取代基对于高亲和力,ERalpha选择性结合的重要性。

  • Base-free two-step synthesis of 1,3-diketones and β-ketoesters from α-diazocarbonyl compounds, trialkylboranes, and aromatic aldehydes

    We describe a convergent, base-free two-step synthesis of 1,3-diketones and β-ketoesters from α-diazocarbonyl compounds, trialkylboranes, and aromatic aldehydes in a three-component process. The synthetic potential of this protocol was underscored by the synthesis of several symmetrical 1,3,5-triaryl-4-alkyl and 1,3,4,5-tetraryl substituted pyrazoles in a three-step sequence.
    我们描述了一种收敛的无基团两步合成方法,通过三组分反应从α-二氮碳酰化合物、三烷基硼烷和芳香醛合成1,3-二酮和β-酮酯。这一合成方法的潜力在于能够在三步反应中合成多种对称的1,3,5-三芳基-4-烷基和1,3,4,5-四芳基取代的吡唑。

  • Pyrazole Ligands:  Structure−Affinity/Activity Relationships and Estrogen Receptor-α-Selective Agonists
    作者:Shaun R. Stauffer、Christopher J. Coletta、Rosanna Tedesco、Gisele Nishiguchi、Kathryn Carlson、Jun Sun、Benita S. Katzenellenbogen、John A. Katzenellenbogen

    We have found that certain tetrasubstituted pyrazoles are high-affinity ligands for the estrogen receptor (ER) (Fink et al. Chem. Biol. 1999, 6, 205-219) and that one pyrazole is considerably more potent as an agonist on the ER alpha than on the ER beta subtype (Sun et al. Endocrinology 1999, 140, 800-804). To investigate what substituent pattern provides optimal ER binding affinity and the greatest enhancement of potency as an ER alpha -selective agonist, we prepared a number of tetrasubstituted pyrazole analogues with defined variations at certain substituent positions. Analysis of their binding affinity pattern shows that a C(4)-propyl substituent is optimal and that a p-hydroxyl group on the N(1)-phenyl group also enhances affinity and selectivity for ER alpha. The best compound in this series, a propylpyrazole triol (PPT, compound 4g), binds to ER alpha with high affinity (ca. 50% that of estradiol), and it has a 410-fold binding affinity preference for ER alpha. It also activates gene transcription only through ER alpha. Thus, this compound represents the first ER alpha -specific agonist. We investigated the molecular basis for the exceptional ER alpha binding affinity and potency selectivity of pyrazole 4g by a further study of structure-affinity relationships in this series and by molecular modeling. These investigations suggest that the pyrazole triols prefer to bind to ER alpha with their C(3)-phenol in the estradiol A-ring binding pocket and that binding selectivity results from differences in the interaction of the pyrazole core and C(4)-propyl group with portions of the receptor where ER alpha has a smaller residue than ER beta. These ER subtype-specific interactions and the ER subtype-selective ligands that can be derived from them should prove useful in defining those biological activities in estrogen target cells that can be selectively activated through ER alpha.
  • Synthesis and Investigations on the Oxidative Degradation of C3/C5-Alkyl-1,2,4-triarylpyrroles as Ligands for the Estrogen Receptor
    作者:Anja Schäfer、Anja Wellner、Ronald Gust
    DOI:10.1002/cmdc.201000537
    日期:2011.5.2
    In this study, we synthesized 1,2,4‐triarylpyrroles as ligands for the estrogen receptor (ER). Two pyrrole series were prepared with either C3‐alkyl or C3/C5‐dialkyl residues. Compounds from both series were susceptible to oxidative degradation—dialkylated compounds (t1/2=33–66 h) to a higher extent than their monoalkylated congeners (t1/2=140–211 h). Nevertheless, stability was sufficient for determination

  • Diaryl-dialkyl-substituted pyrazoles: regioselective synthesis and binding affinity for the estrogen receptor

The binding affinity of some of these pyrazoles for the estrogen receptor (ER) subtypes ERalpha and ERbeta is very high, and the overall affinity pattern suggests the importance of three phenol substituents for high affinity, ERalpha-selective binding.
