ABSTRACT
The purpose of this study is to investigate the intracellular transporters effect and the cytotoxicity of carboxyl nanodiamond (CND) - podophyllotoxin (PPT). Nanodiamond (ND) was treated with mixed carboxylic acid and finally got 64 nm CND by centrifugation, and then it was reacted with PPT to form CND-PPT. UV spectrophotometry was used to calculate the content of PPT in CND-PPT, the particle size distribution and zeta potential were measured by Dynamic laser scattering instrument. CND, PPT, CND-PPT and CND + PPT (physical mixture of CND and PPT) were characterized by Fourier transform infrared spectroscopy, at the same time, thermal analysis and element analysis were used to estimate the content of the PPT in CND-PPT. The affect of CND, PPT, CND-PPT on HeLa cell was measured with MTT assay. The results showed that content of PPT combined with CND accounted for about 10%. MTT assay showed that CND has low cytotoxicity and CND-PPT can increase the water soluble of PPT. As a conclusion, CND as a hydrophilic pharmaceutical carrier combined with PPT is able to increase the water solubility of PPT, at low concentration, CND-PPT can enhance the antitumor activity in comparison with PPT, so CND can be used as a potential anticancer drug carrier.
