AIM OF THIS STUDY: To evaluate the combinational anticancer effect of 23-hydroxybetulinic acid and doxorubicin in vitro and in vivo.
MATERIALS AND METHODS: The effect of combination treatment with 23-hydroxybetulinic acid and doxorubicin was evaluated with a quantitative combination index method based on the median-effect analysis in various cancer cell lines. And in vivo efficacy of combination chemotherapy was also evaluated using ICR mice bearing sarcoma 180 carcinoma tumors.
RESULTS: 23-Hydroxybetulinic acid showed a synergistic cytotoxic effect on multiple cancer cell lines by combined use with doxorubicin. In vivo studies further demonstrated that co-administration of 23-HBA significantly improved the sensitivity of the tumor to doxorubicin through increasing intra-tumor doxorubicin concentration and inhibiting doxorubicin-induced up-regulation of P-gp in tumor.
CONCLUSION: These results suggest that the combined therapy with 23-hydroxybetulinic acid and doxorubicin may be a new promising strategy to promote the clinical chemotherapy, which needs further verification.
