of 0.34-149.10 µM. The inhibition percentage of VEGFR-2 was measured for all the compounds and found to be in the range of 90.09-20.44%. The promising compounds 8, 12, 13, 16 and 17 were selected to measure their possible multikinase inhibitory activity against VEGFR-2 and EGFR. IC50 of the promising compounds were in the range of 247-793 nM for VEGFR-2 in reference to sunitinib (IC50 320 nM), and 369-725 nM
多靶点治疗被认为是成功的癌症治疗方法。通过杂交策略开发小分子多激酶抑制剂可以提供高效且选择性的抗癌药。设计并合成了N-烷基-2-[(4-氧代-3-(4-氨磺酰基苯基)-3,4-二氢喹唑啉-2-基)硫代]乙酰胺衍生物5-18的文库。筛选合成的化合物对MDA-MB-231乳腺癌细胞系的细胞毒活性,显示IC50为0.34-149.10 µM。测量所有化合物的VEGFR-2抑制百分数,发现其在90.09-20.44%的范围内。选择有希望的化合物8、12、13、16和17来测量其针对VEGFR-2和EGFR的可能的多激酶抑制活性。相对于舒尼替尼(IC50 320 nM),VEGFR-2的有希望化合物的IC50为247-793 nM,相对于厄洛替尼(IC50 568 nM),EGFR的IC50为369-725 nM。化合物12和13分别显示出对VEGFR-2和EGFR最有效的活性。测量12和13对MC
