Application
Irinotecan hydrochloride has been used:
- in combination with 5-fluorouracil for screening growth inhibitory functionality in MDA-MB-231 breast cancer cells.
- in chemosensitivity screening of high-grade appendiceal (HGA) and low-grade appendiceal (LGA) organoids.
- as a chemotherapeutic agent in the cytotoxicity studies in combination with heat shock proteins inhibitors (HPSC1) in HT29 colon cancer cells.
Biochem/physiol Actions
The anticancer agent, irinotecan, is a prodrug that is converted by tissue carboxylesterase to 7-ethyl-10-hydroxycamptothecin (SN-38), a potent inhibitor of DNA topoisomerase I. Its action is terminated by glucuronidation by UDP glucuronosyl transferase 1A1 (UGT1A1).

Its action is terminated by glucuronidation by UDP glucuronosyl transferase 1A1 (UGT1A1). It proves useful in radiation treatment of tumors by sensitizing tissue to radiation damage.

Irinotecan is a topoisomerase-I (Top-I) inhibitor used for the treatment of colorectal cancer. DNA demethylating agents, including 5-azacytidine (5-aza), display synergistic antitumor activity with several chemotherapy drugs. 5-Aza may enhance irinotecan cytotoxicity by at least one of the following mechanisms:
