  Investigation of new 2-aryl substituted Benzothiopyrano[4,3-d]pyrimidines as kinase inhibitors targeting vascular endothelial growth factor receptor 2

  摘要：

  Vascular Endothelial Growth Factor (VEGF) pathway has emerged as one of the most important positive modulators of Angiogenesis, a central process implicated in tumour growth and metastatic dissemination. This led to the design and development of anti-VEGF monoclonal antibodies and small-molecule ATP-competitive VEGFR-inhibitors. In this study, we describe the synthesis and the biological evaluation of novel 2-aryl substituted benzothiopyrano-fused pyrimidines 1a-i, 2a-i and 3a-i. The ability of the compounds to target the VEGF pathway was determined in vitro exploiting the compounds' anti-proliferative efficacy against HUVEC cells. The VEGFR-2 inhibition was confirmed by enzymatic assays on recombinant human kinase insert domain receptor (KDR), by cell-based phospho-VEGFR-2 inhibition assays, and by ex vivo rat aortic ring tests. The selectivity profile of the best performing derivatives belonging to series 2 was further explored combining modeling studies and additional assays in a panel of human cell lines and other kinases.

  N,N'-Dibenzyloxalamide (DBO) was identified as a powerful ligand for promoting Cu-catalyzed coupling of heteroanilines with (hetero)aryl halides. For (hetero)aryl chlorides, the coupling reaction occurred at 130 °C with 5 mol % CuBr and 10 mol % DBO. For (hetero)aryl bromides/iodides, coupling reaction took place at 80-100 °C with 1 mol % CuI and 2 mol % DBO. A variety of heteroanilines worked well

  N，N'-二苄基草酰胺（DBO）被确定为一种强大的配体，用于促进Cu催化杂苯胺与（杂）芳基卤化物的偶联。对于（杂）芳基氯，偶联反应在130℃下与5mol％的CuBr和10mol％的DBO发生。对于（杂）芳基溴化物/碘化物，偶合反应在80-100°C下与1 mol％的CuI和2 mol％的DBO进行。各种杂苯胺效果很好，以高到极高的收率提供了芳基化产物。
