Erenapursta (E3330) is a specific inhibitor of AP endonuclease 1 redox domain. E3330 inhibits APE-1 regulation of transcription factors, but does not affect Ape1 DNA repair activity. AP endonuclease 1 (APE1; also known as REF-1) is a multifunctional protein with dual functions in DNA repair and redox regulation of transcription factors. It is involved in apurinic/apyrimidinic endonuclease DNA base excision repair activity, in proofreading exonuclease activity, and in modulating DNA binding activity of several transcription factors including NF-κB, Egr-1, p53, AP-1, CREB, HIF-α, and members of the Pax family. APE1 is overexpressed in several human cancers, and disruption of APE1 function has detrimental effects on cancer cell viability. E3330 significantly reduces the growth of human pancreatic cancer cells in vitro and inhibits pancreatic cancer cell migration.

| 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. |
