Background

Chloroquine diphosphate is used as an antimalarial drug and also functions to increase sensitivity of tumor cells to radiation and chemotherapy via inducing autophagy [1].

Chloroquine diphosphate has been reported as an adjuvant for radiation and chemotherapy for inducing cell autophagy to anti-cancer cells proliferation or metastasis [2]. The mechanism of chloroquine diphosphate inducing cells autophagy is arresting cells in G1, up-regulates the expression of p27 and p53 while down-regulates the expression of CDK2 and cyclin D1 [3].

Apart from anti-malarial, chloroquine diphosphate also has long been reported functioning in cell apoptosis. Pretreated CNE-2 human nasopharyngeal carcinoma cells with chloroquine diphosphate enhanced ionizing radiation induced cell apoptosis via increasing cells autophagic ratio [4]. When treated with mouse breast cancer 4T1 cells, chloroquine diphosphate treatment inhibited cellular proliferation and viability which resulted in cells apoptosis in a time- and dose- dependent manner [2]. In human colon cancer DLD-1 cells, combination of 5-FU and chloroquine diphosphate could inhibit cells proliferation via inducing autophagy [3].

In mouse model with 4T1 cells subcutaneous xenograft, chloroquine diphosphate treatment significantly inhibited tumor growth and tumor cells metastasis to the lung, thus enhanced the mice survival [2]. In BALB/c mice injected with colon26 cells subcutaneously, chloroquine diphosphate cooperated with 5-FU significantly enhanced the inhibition of tumor growth induced by 5-FU through increasing the ratio of apoptotic cells [5].
