中文摘要：

目的探讨抗癌新药阿帕替尼治疗乳腺癌的潜在作用靶点和作用机制。方法研究采用Pharm Mapper反向分子对接技术结合生物信息学分析，预测阿帕替尼的潜在作用靶点，并采用分子对接软件Autodock 4．0将预测得到的蛋白靶点与阿帕替尼进行分子对接分析，研究阿帕替尼化合物与靶蛋白的相互作用。结果研究发现，4个蛋白Celldivisionproteinkinase2、GT—PaseHRas、NONE和CytochromeP4502C9可能是阿帕替尼治疗乳腺癌的潜在重要作用靶点。阿帕替尼与这4个蛋白靶点之间有较稳定的氢键结合，并且具有较低的结合自由能，结合稳定。结论阿帕替尼可能通过调控Cell division proteinkinase2、GTPaseHRas、NONE和Cytochrome P4502C9的功能或生物作用来参与乳腺癌的治疗。本实验为阿帕替尼治疗乳腺癌的作用机制的深入探讨提供了理论依据和线索。

英文摘要：

OBJECTIVE To study the potential targets and action mechanism of apatinib-treated breast cancer. METHODS Combination with bioinformatic analysis, PharmMapper reverse docking technology was used to predict potential targets of apatinib and docking was performed using Autodock 4. 0 to examine the interaction of aptinib wih predicted protein targets. RESULTS Cell divi- sion protein kinase 2, GTPase HRas, NONE and cytochrome 19450 2C9 were found to be the potential targets of apatinib-treated breast cancer. Stable hydrogen bonds were formed between apatinib and the four predicted targets, and the binding free energy was low. CONCLUSION Apatinib maybe participate the functional regulation or biological action of cell division protein kinase 2, GTPase HRas, NONE and Cytochrome P4502C9 to treat breast cancer, which provides a theoretical basis and a clue for further exploration of the mechanism research of apatinib-treated breast cancer.
