RK-33 is a first-in-class, potent and selective DDX3 (RNA helicase) inhibitor, it binds to DDX3 and abrogates its activity. RK-33 caused G1 cell cycle arrest, induced apoptosis, and promoted radiation sensitization in DDX3-overexpressing cells. Inhibition of DDX3 by RK-33 also promotes tumor regression, thus providing a compelling argument to develop DDX3 inhibitors for lung cancer therapy. RK-33 radiosensitizes prostate cancer cells by blocking the RNA helicase DDX3.
| Cell Experiment | |
|---|---|
| Cell lines | MDA-MB-231 cells |
| Preparation method | Healthy, 60-70% confluent MDA-MB-231 cells are transduced with shDDX3 lentivirus particles. Knockdown of DDX3 expression is confirmed both by qRT-PCR and immunoblotting. MDA-MB-231 cells are treated with RK-33 (7.5 μM) for 12 h and harvested for RNA. Microarray experiments are performed. |

| Mizoribine
Mizoribine (Bredinin) is an imidazole nucleoside and an immunosuppressive agent with an IC50 of approximately 100 μM. Mizoribine inhibits replication of SARS-CoV with IC50s of 3.5 μg/mL and 16 μg/mL for SARS-CoV Frankfurt-1 and SARS-CoV HKU39849, respectively. |
| Capecitabine
Capecitabine is an orally-administered chemotherapeutic agent. Capecitabine is a precursor, that is enzymatically converted to 5-fluorouracil in the tumor, where it inhibits DNA synthesis and slows growth of tumor tissue. Capecitabine may inhibit cytochrome CYP2C9 enzyme, and therefore increase levels of substrates such as phenytoin and other substrates of CYP2C9. |
