摘要

A solution-phase multiple-parallel synthesis approach was employed for the preparation of 6- , 7-and 8-aryl-substituted chromenone libraries, which were screened as inhibitors of the DNA repair enzyme DNA-dependent protein kinase (DNA-PK). These studies resulted in the identification of 8-dibenzothiophen-4-yl-2-morpholin-4-yl-chromen-4-one (NU7441) as a highly potent and selective DNA-PK inhibitor (IC50= 14nM), exhibiting ATP-competitive ...
