Abstract:
Protopanaxadiol (PPD) has inhibitory effects on many tumors and receives much attention. However,it has poor water solubility and low utilization, which limits its clinical application. Considering these issues,in this study,we used hollow gold nanoparticles as transport carriers of PPD and synthesized PPD hollow gold nanoparticles (HAuNs). We conducted a number of experiments to investigate the in vitro anti-laryngeal cancer Hep-2 effect of a PPD HAuNs carrier. High performance liquid chromatography(HPLC) was used to detect the sustained release effect of PPD HAuNs. MTT assay was used to detect the inhibitory effect of PPD HAuNs on the proliferation of Hep-2 cells. Effect of PPD HAuNs on Hep-2 cell apoptosis was investigated by flow cytometry. The results of in vitro release showed that PPD HAuNs had sustained release effect. Compared with blank control group,HAuNs group and PPD group,the survival rate of Hep-2 cells in HAuNs-PEG-PPD group decreased more significantly and the apoptosis rate increased more significantly (p<0.01). PPD HAuNs could significantly enhance anti-laryngeal cancer effect of PPD in vitro and promote the apoptosis of tumor cells. It promotes tumor cell apoptosis, and is expected to be a new PPD drug delivery system, further promoting the application of PPD in clinical anti-laryngeal cancer.
