Abstract

The invention provides a cyclomalonamide 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 is a halogen group; and R2 is a halogen group or a group as described in the specification, or a group formed by R1 and R2 together. 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.

Description

technical field [0001] The invention belongs to the technical field of biomedicine and relates to an antitumor compound, in particular to a cyclomalonamide compound with antitumor activity and a preparation method and application thereof. Background technique [0002] Malignant tumors, as one of the largest public health problems in the world, have greatly endangered human health and will become the number one killer of human beings in the new century. Malignant tumors are no longer just a serious disease in developed industrial countries, and developing countries are facing a greater burden of disease. Chemotherapy, as one of the important means of treating tumors, has undergone tremendous development and progress in the past three decades, and a large number of clinical antitumor drugs with different mechanisms of action have been obtained. However, antineoplastic drugs also have many adverse reactions, such as hair loss, vomiting, bone marrow suppression, rapid drug resi...
