4-Anilinoquinazoline ureas were envisaged according to the hybrid-design approach based upon two privileged pharmacophores in kinase drug discovery, i.e. 4-anilinoquinazoline and unsymmetrical diaryl urea. In our structure–activity relationships (SAR) campaign, title compounds were synthesized and profiled in biochemical assay for their kinase inhibitory activity. Title compounds 18–20 were found to be multikinase inhibitors with profound activity against BRAF, BRAF V600E, VEGFR-2 and EGFR. Molecular docking into DFG-out conformations of BRAF and VEGFR-2 suggested that they might be type II inhibitors.

喹唑啉和不对称二芳基
脲。在我们的构效关系 (
SAR) 活动中,合成了标题化合物,并通过生化分析对其激酶抑制活性进行了分析。标题化合物 18-20 被发现是多激酶
抑制剂,对 BRAF、BRAF V600E、V
EGFR-2 和
EGFR 具有显着活性。 BRAF 和 V
EGFR-2 的 DFG-out 构象的分子对接表明它们可能是 II 型
抑制剂。
