Two new compounds with anticancer effects of N-[4-chloro-3-(trifluoromethyl)phenyl]-[4-(N-methyl-formamide)(4-pyridyloxy)phenyl]-thiourea and N-[4-chloro-3-(trifluoromethyl)phenyl]-[4-(N-methyl-formamide)(4-pyridylthio)phenyl]-thiourea, and salts thereof are disclosed. Preparation methods of the two new compounds and pharmaceutical compositions containing the new compounds are further disclosed. Experimental studies show that the two new compounds can effectively inhibit the activity of Raf and VEGFR protein kinase, widely inhibit growth of various types of human tumor cell lines and further induce apoptosis of tumor cells. Human tumor heterograft model investigation proves that the two new compounds are effective antineoplastic agents, and can sharply inhibit growth of human liver cancer cells, lung cancer cells and intestinal cancer cells in vivo. Furthermore, the anticancer effects of the compounds are much better than that of Sorafenib.
两种新化合物具有抗癌作用,分别为N-[4-氯-3-(三氟甲基)苯基]-[4-(N-甲基-甲酰胺)(4-吡啶氧基)苯基]-硫脲和N-[4-氯-3-(三氟甲基)苯基]-[4-(N-甲基-甲酰胺)(4-吡啶硫基)苯基]-硫脲,以及它们的盐。进一步披露了这两种新化合物的制备方法和含有这些新化合物的药物组合物。实验研究表明,这两种新化合物可以有效抑制Raf和VEGFR蛋白激酶的活性,广泛抑制各种类型的人类肿瘤细胞系的生长,并进一步诱导肿瘤细胞凋亡。人类肿瘤异种移植模型研究证明,这两种新化合物是有效的抗肿瘤药物,可以显著抑制体内人类肝癌细胞、肺癌细胞和肠癌细胞的生长。此外,这些化合物的抗癌作用远远优于索拉非尼。
