IDO2-siRNA Carried by
    Current molecular pharmacology, 2023, Volume: 16, Issue:8

    Melanoma, a highly malignant skin cancer, is a hot topic in oncology treatment research. Nowadays, tumor immunotherapy, especially immunotherapy combined with other therapies, has attracted more and more attention. Indoleamine 2,3-dioxygenase 2 (IDO2), a ratelimiting enzyme of the tryptophan metabolism pathway in the urine of dogs with immunosuppression, is highly expressed in melanoma tissue. Additionally, IDO2 significantly inhibits the anti-tumor immunity of the body and has become a novel target of melanoma treatment. Nifuroxazide, as an intestinal antibacterial agent, was found to be able to inhibit Stat3 expression and exert an anti-tumor effect. Therefore, the present study aimed to examine the therapeutic effect of a self-designed IDO2-small interfering RNA (siRNA) delivered by attenuated. The effect of nifuroxazide on melanoma was detected by flow cytometry, CCK-8 and colony- forming ability assays, respectively,. The results demonstrated that the combination therapy effectively inhibited the phosphorylation of Stat3 and the expression level of IDO2 in melanoma cells, which effectively inhibited tumor growth and prolonged the survival time of tumor-bearing mice. The mechanistic study revealed that, compared with control groups and monotherapy groups, the combination treatment group reduced the atypia of tumor cells, increased the apoptotic rate, enhanced the infiltration of T lymphocytes in tumor tissue and increased the CD4. In conclusion, IDO2-siRNA combined with nifuroxazide therapy could serve a significant role in the treatment of melanoma-bearing mice, enhance the tumor immunity and provide an experimental basis for identifying a novel combination method for the treatment of melanoma clinically.

ALDH1 Bio-activates Nifuroxazide to Eradicate ALDH
    Cell chemical biology, 2018, 12-20, Volume: 25, Issue:12

    5-Nitrofurans are antibiotic pro-drugs that have potential as cancer therapeutics. Here, we show that 5-nitrofurans can be bio-activated by aldehyde dehydrogenase (ALDH) 1A1/1A3 enzymes that are highly expressed in a subpopulation of cancer-initiating (stem) cells. We discover that the 5-nitrofuran, nifuroxazide, is selective for bio-activation by ALDH1 isoforms over ALDH2, whereby it both oxidizes ALDH1 and is converted to cytotoxic metabolites in a two-hit pro-drug mechanism. We show that ALDH1

5-Nitrofurans and Cancer: Teaching an Old Drug New Tricks.
    Cell chemical biology, 2018, 12-20, Volume: 25, Issue:12

    Aldehyde dehydrogenases (ALDHs) are known as robust markers of tumor-initiating cells and as potential therapeutic targets for cancer. In this issue of Cell Chemical Biology, Sarvi et al. (2018) demonstrate that 5-nitrofuran antibiotics can target ALDH-expressing cancer cells in two distinct ways, effectively depleting melanomas of their tumor-initiating cells.

Nifuroxazide exerts potent anti-tumor and anti-metastasis activity in melanoma.
    Scientific reports, 2016, Feb-02, Volume: 6

    Melanoma is a highly malignant neoplasm of melanocytes with considerable metastatic potential and drug resistance, explaining the need for new candidates that inhibit tumor growth and metastasis. The signal transducer and activator of the transcription 3 (Stat3) signaling pathway plays an important role in melanoma and has been validated as promising anticancer target for melanoma therapy. In this study, nifuroxazide, an antidiarrheal agent identified as an inhibitor of Stat3, was evaluated for its anti-melanoma activity in vitro and in vivo. It had potent anti-proliferative activity against various melanoma cell lines and could induce G2/M phase arrest and cell apoptosis. Moreover, nifuroxazide markedly impaired melanoma cell migration and invasion by down-regulating phosphorylated-Src, phosphorylated-FAK, and expression of matrix metalloproteinase (MMP) -2, MMP-9 and vimentin. It also significantly inhibited tumor growth without obvious side effects in the A375-bearing mice model by inducing apoptosis and reducing cell proliferation and metastasis. Notably, nifuroxazide significantly inhibited pulmonary metastases, which might be associated with the decrease of myeloid-derived suppressor cells (MDSCs). These findings suggested that nifuroxazide might be a potential agent for inhibiting the growth and metastasis of melanoma.
