  Development of Novel EDG3 Antagonists Using a 3D Database Search and Their Structure−Activity Relationships

  摘要：

  Sphingosine-1-phosphate (SIP) is an intracellular second messenger and an extracellular mediator through endothelial differentiation gene (EDG) receptors, which are a novel class of G-protein-coupled receptors. Although EDG has attracted much attention because of its various roles, no selective agonists or antagonists have yet been developed. This could account for the delay in clarifying the physiological roles of members of the EDG family. Because precise structural information on EDG receptors is not yet available, pharmacophore models were generated based on structural information for SIP using the rational drug design software Catalyst. Novel antagonists, 2-alkylthiazolidine-4-carboxylic acids, were retrieved from a three-dimensional database search using the pharmacophore models, and these showed activity for EDG3. On the basis of their nonphosphoric acid structure, more potent antagonists, 2-(m- or p-heptylphenyl)thiazolidine-4-carboxylic acid, were developed.

  zinc bromides and regioconvergent Negishi coupling with aryl or alkenyl triflates. The use of a suitable phosphine ligand favoring Pd migration enabled the selective formation of the linear cross‐coupling product. Subsequently, mixtures of secondary alkyl bromides were prepared from linear alkanes by standard bromination, and regioconvergent cross‐coupling then provided access to the corresponding linear

  碳氢化合物仍然是功能化有机分子的最重要前体，在新型CH键功能化方法的发现中引起了人们的兴趣。我们在这里描述了一种新的步骤经济的方法，该方法使C-C键能够在直链烷烃的末端位置进行构建。首先，我们表明仲烷基溴化物可以原位转化为烷基溴化锌和与会聚芳基或烯基三氟甲磺酸酯的区域收敛的Negishi。使用合适的膦配体促进Pd迁移，可以选择性形成线性交叉偶联产物。随后，通过标准溴化反应，由直链烷烃制备仲烷基溴化物的混合物，然后通过区域会聚交叉偶联，仅需两个步骤即可获得相应的线性芳基化产物。

  annulation reactions of benzoylacetonitriles with diazo compounds proceed efficiently in the presence of an iridium catalyst to give substituted naphtho[1,8‐bc]pyrans by sequential cleavage of C(sp2)−H/C(sp3)−H and C(sp2)−H/O−H bonds. Interestingly, the reactions involving cyclic diazo compounds and open‐chain diazo compounds lead to different types of naphtho[1,8‐bc]pyrans. Most products are obtained
