Merck, I1406-50MG, Irinotecan hydrochloride

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).
