Abstract

The invention discloses a thieno 2,4-substituted pyrimidine compound of which the general formulas are (I), (II), (III) and (IV), or pharmaceutically acceptable salt or stereisomer or a prodrug molecule, and a pharmaceutical composition and application thereof. The thieno 2,4-substituted pyrimidine compound can effectively restrain abnormal expression of Aurora kinase, has specific inhibited effect on Aurora-A and Aurora-B, can be applied to a novel field of molecular targeting treatment, and has strong inhibitory activity on an excessive hyperplasia disease, especially cervical tumor cells, human macrophage line leukemia cell, and human t-lymphocyte line cancer cell.

Description

technical field [0001] The invention relates to the field of chemistry and medicine, in particular to thieno 2,4 substituted pyrimidine compounds and their pharmaceutical composition and application. Background technique [0002] Tumor molecular targeted therapy is a treatment method based on the selective killing of tumor cells by chemical or biological means to key molecules closely related to tumor growth. The characteristics of targeted therapy are: high specificity, strong selectivity, and mild side effects; when used in combination, it can strengthen the curative effect of traditional chemotherapy and radiotherapy, and reduce postoperative recurrence. Gleevec (STI571, imatinib, commodity The targeted drug represented by Gleevec has ushered in a new era for cancer chemotherapy. Tumor targeted therapy has developed rapidly in just a few years. The emergence of tumor targeted therapy has had an impact on traditional drug administration concepts and modes. For example, d...
