Abstract:
Objective To evaluate the antitumor effect of corosolic acid and its impact on CAM and YSM angiogenesis.Methods The effects of CRA on A549 proliferation was studied by MTT method in vitro.Tumor-bruden nude mice model were established by injecting A549 lung cancer cell marked with bioluminescent to nude mice,and the growth of tumor in mice were detected by IVIS small animal in vivo imaging system.Experiment of chicken embryos eggs are used to observe the role of drugs on CAMand YSMblood vessels. Results The value of IC50 of CRA for A549 in vitro was 26.8μg/mL.A tumor-burdened animal experiment results showed that the CRA to A549 solid tumor has a certain therapeutic effect.CAM and YSM blood vessels of chicken embryos eggs treated with CRA were decreased significantly than negative control group.Conclusion CRA has certain therapeutic effect for A549,which may be related to the inhibition of angiogenesis in tumor tissues.
