Angiogenesis is modulated by a multitude of pro-angiogenic factors including VEGFR-2, Tie-2, and EphB4. Moreover, their crosstalk also had been well elaborated. We have identified several diarylurea-based VEGFR-2 inhibitors as potential anti-angiogenesis agents. As a continuation to our previous research, two series of diaryl malonamide and diaryl thiourea derivatives have been developed as multiplex VEGFR-2/Tie-2/EphB4 inhibitors. Interestingly, the biological evaluation indicated that several compounds bearing trifluoromethyl or trifluoromethoxyl exhibited promising multiplex inhibition against angiogenesis-related VEGFR-2, Tie-2, and EphB4. The representative compound (18a) displayed both potent multi-targeted RTK inhibition and considerable antiproliferative activities against human umbilical vein endothelial cells (EA.hy926). These results will contribute to the discovery of novel muti-targeted anti-angiogenesis agents.

The invention provides a diarylthiourea compound with antitumor activity, and a preparation method and application thereof. The compound has a structural formula as described in the specification. In the structural formula, R1 and R2 are selected from the group consisting of a halogen group or a group formed by R1 and R2 together; and Ar is a nitrogen heterocyclic ring of pyridine, indazole or quinazoline. The compound provided by the invention has good inhibitory activity to VEGFR-2 kinase, so a signal channel induced by the VEGFR-2 kinase can be blocked through inhibition of the activity of the VEGFR-2 kinase, and proliferation and migration of tumor cells are inhibited; thus, the compound can be applied in preparation of antitumor drugs. Meanwhile, the preparation method for the compound has the following advantages: raw materials are easily available; reaction conditions are mild; the process of reaction is simple to operate; and used reagents are cheap.
