Abstract

A simple, low molecular weight camptothecin-lysine conjugate is reported to self-assemble into nanotubes with diameters of 70-100nm and a drug loading level of 60.5%. The nanotubes exhibited promising in vitro cytotoxicity against cancer cell lines A549, NCI-H460 and NCI-H23. The release of active camptothecin was highly dependent on conjugate concentration, temperature and pH of the solution.
