  • Growth inhibitory effects of Irinotecan in human pancreatic cancer cells. Panc1 cells were plated in triplicates into 48-well plates at a density of 10,000 cells/ml. After 24 hours, complete culture medium was changed into fresh low-serum-containing medium (1% FBS) containing DMSO (control) or indicated doses of Irinotecan (Selleckchem). Cell viability 72 hours after treatment was determined by AlamarBlue assay (Invitrogen) according to manufacturer's instructions. Results are expressed as percentages of control, which was arbitrarily assigned 100% viability, and represented as the mean ± standard deviation (SD) of the tripicate wells.

Biological Activity

Description Irinotecan prevents DNA from unwinding by inhibition of topoisomerase 1.
Features Irinotecan is a prodrug that is used to treat metastatic colorectal cancer.
Targets
Topo I [1]
In vitro

Irinotecan is activated to SN-38 by carboxylesterases to become able to interact with its target, topoisomerase I. Irinotecan 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 Irinotecan is markedly different, reaching consistently higher levels in HT-29 cells than in LoVo cells. [1] The lactone E-ring of Irinotecan 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 Irinotecan to SN-38. At equal concentrations of Irinotecan and SN-38 glucuronide, the rate of beta-glucuronidase-mediated SN-38 production is higher than that formed from Irinotecan in both tumour and normal tissue. [2] Irinotecan is also converted to SN-38 in intestines, plasma and tumor tissues. [3] Irinotecan is significantly more active in SCLC than in NSCLC cell lines, whereas no significant difference between histological types is observed with SN-38. [4]

NFκB p65 / phospho-NFκB p65 / NFκB p50 / IκBα / p27Kip1; 

PubMed: 22206574     


For Western blot analysis (B), cytoplasmic proteins were analyzed using antibodies against NFκB p65 and p50, phospho-NFκB p65, IκBα and p27Kip1. In the presence of irinotecan, there was a loss of cytoplasmic NF-κBp65, but in the presence of sorafenib, this loss was greatly reduced, corresponding to a decrease in phosphorylation of NF-κBp65. In addition, compared to treatment with sorafenib or irinotecan alone, there was increased expression of IκBα following treatment with sorafenib and irinotecan. Lastly, following treatment with irinotecan and sorafenib irinotecan combination, there was decreased expression of p27Kip1 compared to sorafenib treatment alone.

a Gimatecan significantly inhibited the expression of TopI, pAKT, pMEK, and pERK, and activated the expression of p-p38 MAPK and pJNK2 in SNU-1 cells. b Gimatecan significantly inhibited the expression of pAKT and pERK in NCI-N87 cells. Cells were starved in serum-free medium overnight, exposed to gimatecan or irinotecan for 48 h and harvested at 70–80% confluence. Total protein of SNU-1 and NCI-N87 was extracted and the expression of TopI, pAKT, pMEK, pERK, p-p38 MAPK and pJNK2 were assessed by western-blotting

BT12 cells were incubated with sorafenib or vehicle for 30 minutes followed by treatment with irinotecan for an additional 2 hours. For indirect immunofluorescence (A), cells were fixed and stained with antibodies to NF-κB followed by fluorescent labeled secondary antibodies. Concurrent DAPI stain was used to localize the nuclei (lower panel). Slides were visualized using a fluorescent microscope and random fields were photographed. The cytoplasmic staining seen in untreated and sorafenib treated cells was significantly reduced following treatment with irinotecan. However, the addition of sorafenib enabled the cells to maintain cytoplasmic staining in the presence of irinotecan.

Growth inhibition assay
Cell viability; 

PubMed: 25973791     


The sensitivity of eight colon cancer cell lines to irinotecan was measured using the CCK-8 assay. For the CCK-8 assay, cells were exposed to irinotecan at given concentrations for 72 h before measurement. The cell viability was presented as the percentage relative to untreated cells.

25973791
In vivo In COLO 320 xenografts, Irinotecan induces a maximum growth inhibition of 92%. [5] A single dose of Irinotecan 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. [6]

+ Expand
  • Cell lines: LoVo and HT-29 cells
  • Concentrations: 0 μM -100 μM
  • Incubation Time: 48 hours
  • Method:

    Exponentially growing cells (LoVo and HT-29 cells) are seeded in 20 cm2 Petri dishes with an optimal cell number for each cell line (2 × 104 for LoVo cells, 105 for HT-29 cells). They are treated 2 days later with increasing concentrations of Irinotecan or SN-38 for one cell doubling time (24 hours for LoVo cells, 40 hours for HT-29 cells). After washing with 0.15 M NaCl, the cells are further grown for two doubling times in normal medium, detached from the support with trypsin-EDTA and counted in a hemocytometer. The IC50 values are then estimated as the Irinotecan or SN-38 concentrations responsible for 50% growth inhibition as compared with cells incubated without Irinotecan or SN-38.

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
