Tumor growth inhibition rate in 4T1.2 tumor bearing mice

Treatments IR (%)
CPT 5 mg/kg 43.69
PEG5K-Fmoc-VE2/CPT-VE 5 mg/kg 56.06
PEG5K-Fmoc-VE2/CPT-S-S-VE 5 mg/kg 81.90
PEG5K-Fmoc-VE2/CPT-S-S-VE 10 mg/kg 93.48

IR % = (1 – tumor volume in the treated group/tumor volume in the saline group) × 100%

IR % was calculated based on the tumor volume on day 21
