작용 메커니즘 (Mechanism of Action)

특징
Irinotecan is a prodrug that is used to treat metastatic colorectal cancer.
Targets/IC50/Ki
Topo I
(LoVo, HT-29 cells)
시험관 내(In vitro)
Irinotecan is activated to SN-38 by carboxylesterases to become able to interact with its target, topoisomerase I. This compound induces similar amounts of cleavable complexes at its IC50 in LoVo cells and HT-29 cell lines. SN-38 induces a concentration-dependent formation of cleavable complexes, which is not significantly different in LoVo cells and HT-29 cell lines. Cell accumulation of this chemical is markedly different, reaching consistently higher levels in HT-29 cells than in LoVo cells. The lactone E-ring of this compound and SN-38 hydrolyses reversibly in aqueous solutions, and the interconversion between the lactone and carboxylate forms is dependent on pH and temperature. Liver is primarily responsible for the activation of this agent to SN-38. At equal concentrations of this drug and SN-38 glucuronide, the rate of beta-glucuronidase-mediated SN-38 production is higher than that formed from this compound in both tumour and normal tissue. It is also converted to SN-38 in intestines, plasma and tumor tissues. This agent is significantly more active in SCLC than in NSCLC cell lines, whereas no significant difference between histological types is observed with SN-38.
생체 내(In vivo)
In COLO 320 xenografts, Irinotecan induces a maximum growth inhibition of 92%. A single dose of this compound significantly increases amounts of topoisomerase I covalently bound to DNA in stomach, duodenum, colon and liver. Concomitantly, the Irinotecan-treated group shows significantly higher amounts of DNA strand breaks in colon mucosa cells compared to the control group.
