In vitro cytotoxicity of different drug forms to PC-3 cells under different conditions. Cell viability of PC-3 after treated with DA-ss-DT, SA-ss-DT, and P-ss-DT at pH 6.5 (A) and 7.4 (B). (C) Cell viability of DA-ss-DT and DA-cc-DT incubated with 1 mM GSH to PC-3 cells for 48 hours. All data are represented as mean±SD (n=6). **P<0.01.
