    Synthesis of 5-bromo-6-methyl imidazopyrazine, 5-bromo and 5-chloro-6-methyl imidazopyridine using electron density surface maps to guide synthetic strategy
    摘要:
    Small heteroaromatic rings are valuable monomers in drug discovery that can enable rapid access to novel and desirable chemical space. Installation of a synthetic handle on a heteroaromatic core may be difficult if steric and electronic factors are not in alignment with the desired transformation. Described are practical routes for the construction of 5-bromo-6-methyl imidazopyrazine (1) as well as 5-bromo and 5-chloro-6-methyl imidazopyridines (2a and 2b), which were developed using electron density surface maps encoded with ionization potential to guide synthetic strategy.

    protein-coupled receptors (GPCRs) are capable of downstream signaling through distinct noncanonical pathways such as β-arrestins in addition to the canonical G protein-dependent pathways. GPCR ligands that differentially activate the downstream signaling pathways are termed functionally selective or biased ligands. A class of novel non-catechol G protein-biased agonists of the dopamine D1 receptor (D1R) was
    G蛋白偶联受体(GPCR)除通过G蛋白依赖性经典途径外,还能够通过不同的非经典途径(例如β-arrestin)进行下游信号传导。差异激活下游信号传导途径的GPCR配体称为功能选择性或偏向配体。最近公开了一类新型的多巴胺D1受体(D1R)的非儿茶酚G蛋白偏向的激动剂。我们进行了第一个全面的结构-功能选择性关系研究,测量了该支架的四个区域的GS和β-arrestin2募集活动,结果得到了50多个具有不同功能选择性谱的类似物。与起始化合物相比,某些化合物成为β-arrestin2募集的有效全效激动剂,而其他化合物则显示出更高的GS偏倚。具有改变的功能选择性特征的类似物的药代动力学测试表明,血脑屏障渗透性极佳。这项研究为研究D1R的配体偏倚提供了新颖的工具,并为开发下一代有偏向的D1R配体铺平了道路。
