Paragraph 0037; 0040-0041; 0086-0087, (2020/10/28)
The invention provides an N2-carbamylaryl-2-aminopyrimidine derivative and a medical application thereof. The N2-carbamylaryl-2-aminopyrimidine derivative provided by the invention comprises an optical isomer of the N2-carbamylaryl-2-aminopyrimidine derivative and pharmaceutically acceptable salt thereof. Pharmacodynamic research shows that the traditional Chinese medicine composition has no toxicor side effect, the compound has an FLT3 inhibitory activity. The proliferation inhibition activity is realized on various leukemia cell strains; a medium inhibition effect is achieved on breast cancer cells; moreover, the polypeptide is effective for multiple mutations of AML, such as internal tandem repeat mutation of a near-membrane structural domain and D835 point mutation of an activated ring in a kinase structural domain, almost has no inhibition effect on c-KIT, can overcome drug resistance brought by clinical point mutation, can reduce toxic and side effects of bone marrow inhibition,and can be applied to preparation of antitumor drugs. The structures of the general formulas Ia and Ib of the N2-carbamylaryl-2-aminopyrimidine derivative are shown in the specification,
Diarylurea compound with antitumor activity, and preparation method and application thereof
-
Paragraph 0039-0040, (2017/07/19)
The invention provides a diarylurea 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 hydrogen, alkane groups or halogen groups. 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.
