  Structure–Activity Relationship Refinement and Further Assessment of 4-Phenylquinazoline-2-carboxamide Translocator Protein Ligands as Antiproliferative Agents in Human Glioblastoma Tumors

  摘要：

  Structure-activity relationships (SARs) within the 4-phenylquinazoline-2-carboxamide series of translocator protein (TSPO) ligands have been explored further by the synthesis and TSPO binding affinity evaluation of N-benzyl-N-ethyl/methyl derivatives variously decorated at the 6-, 2'-, 4'-, and 4″-positions. Most of the compounds showed high affinity with K(i) values in the nanomolar/subnanomolar range. A pharmacophore model was developed and employed to better address SAR data presented by the new TSPO ligands. A subset of the new compounds (5, 8, 12, and 19) were tested for their ability to inhibit the viability of human glioblastoma cell line U343. The observed antiproliferative effect was demonstrated to be specific for compound 19, endowed with the best combination of binding affinity and efficacy. Furthermore, the ability of 19 to induce mitochondrial membrane dissipation (Δψ(m)) substantiated the intracellular pro-apoptotic mechanism activated by the binding of this class of ligands to TSPO.

  Abstract A one-pot method for joining three separate components leading to an assortment of 4-arylquinazolines (27 examples) in good to excellent yields is described. The method consists of a palladium(II)-catalyzed­ cascade reaction involving C(sp)–C(sp2) coupling followed by intramolecular C–N bond formation. The reaction was readily scaled up to gram quantity and successfully applied to the synthesis

  摘要 描述了一种通过一锅法将三个独立的组分连接在一起，从而以良好至极好的收率得到各种4-芳基喹唑啉（27个实例）的方法。该方法由钯（II）催化的级联反应，涉及C（sp）–C（sp 2）偶联，然后形成分子内C–N键。该反应易于按比例放大至克量，并成功地用于合成易位蛋白（TSPO）配体。 出版历史 收到：2020年8月24日 修订后接受：2020年9月16日 发布日期： 2020年10月19日（在线） ©2020年。Thieme。版权所有 Georg Thieme Verlag KGRüdigerstraße14，70469斯图加特，德国
