Vascular endothelial growth factor receptor-2 (VEGFR-2) kinase inhibition is a well-established strategy to promptly tackle tumor growth by suppression of angiogenesis. We report herein a series of 5-anilinoquinazoline derivatives substituted by 1,3-disubstituted urea. All the newly synthesized compounds described were evaluated for VEGFR-2 kinase inhibition and antiproliferative activity against various cancer cells. The novel 1-aryl, 3-aryl-disubstituted urea quinazolines were effective VEGFR-2 kinase inhibitors with in vitro IC50 values in the submicromolar range (compound 6f, IC50 12.0 nM), but showed a weak to moderate inhibitory activity on cancer cells. Molecular interactions of the compounds were studied using molecular docking studies.
血管内皮生长因子受体-2(VEGFR-2)激酶抑制是一种公认的策略,旨在通过抑制血管生成来迅速应对肿瘤生长。本文报告了一系列以1,3-双取代脲为取代基的5-氨基喹唑啉衍生物。所有新合成的化合物均经过评估,以测试其对VEGFR-2激酶的抑制作用和对多种癌细胞的抗增殖活性。新型的1-芳基、3-芳基-双取代脲喹唑啉是有效的VEGFR-2激酶抑制剂,其体外IC50值在亚微摩尔范围内(化合物6f,IC50为12.0 nM),但在癌细胞上表现出较弱到中等的抑制活性。采用分子对接研究了这些化合物的分子相互作用。
