Halofuginone (RU-19110), a Febrifugine derivative, is a competitive prolyl-tRNA synthetase inhibitor with a Ki of 18.3 nM. Halofuginone is a specific inhibitor of type-I collagen synthesis and attenuates osteoarthritis (OA) by inhibition of TGF-β activity. Halofuginone is also a potent pulmonary vasodilator by activating Kv channels and blocking voltage-gated, receptor-operated and store-operated Ca2+ channels. Halofuginone has anti-malaria, anti-inflammatory, anti-cancer, anti-fibrosis effects.

| 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. |
