Antitumor effect of peptide mPEG-SC_20k-HM-3 and oxaliplatin combination against human hepatocellular carcinoma SMMC-7721 in nude mice

mPEG-SC_20k-HM-3 is a novel anti-angiogenesis peptide with integrin affinity. To investigate the anti-tumor activities of mPEG-SC_20k-HM-3 and oxaliplatin(OXA)combination, a transplanted tumor model of human hepatocellular carcinoma SMMC-7721 in nude mice was established. Jin′s formula to evaluate the combination effect was used. Data suggested that the anti-tumor activities of combined groups were better than those of single drug(P< 0. 05). Inhibition rate of group 8(OXA 7. 5 mg/kg and mPEG-SC_20k-HM-3 73. 4 mg/kg)was 84. 6%, which showed remarkable superiority to group 3(OXA 7. 5 mg/kg)and group 4(mPEG-SC_20k-HM-3 73. 4 mg/kg). The Q of group 8 was 1. 164(> 1. 15). This combination had synergistic effect. Combination of mPEG-SC_20k-HM-3 and oxaliplatin is a method of inhibiting hepatocellular carcinoma.
