| | Irinotecan Usage And Synthesis |
| Uses | (+)-Irinotecan is a Topo I inhibitor. | | Uses | Irinotecan is a topoisomerase I inhibitor for LoVo cells and HT-29 cells with IC50 of 15.8 μM and 5.17 μM, respectively | | Definition | ChEBI: A member of the class of pyranoindolizinoquinolines that is the carbamate ester obtained by formal condensation of the carboxy group of [1,4'-bipiperidine]-1'-carboxylic acid with the phenolic hydroxy group of (4S)-4,11-diethyl-4,9-dihydro
y-1H-pyrano[3',4':6,7]indolizino[1,2- hydrochloride]quinoline-3,14-dione. Used (in the form of its hydrochloride salt trihydrate) in combination with fluorouracil and leucovorin, for the treatment of patients with metastatic adenocarcino
a of the pancreas after disease progression following gemcitabine-based therapy. It is converted via hydrolysis of the carbamate linkage to its active metabolite, SN-38, which is ~1000 times more active. | | Brand name | Camptosar (Pharmacia &Upjohn)
. | | Biological Activity | irinotecan (cpt-11), a prodrug for treating metastatic colorectal cancer, is a topoisomerase i inhibitor for lovo cells and ht-29 cells with ic50 of 15.8 μm and 5.17 μm, respectively [1].in vivo, irinotecan is converted to sn-38, its most active metabolite, by carboxylesterase converting enzyme (cce) [2]. | | in vitro | irinotecan induced similar amounts of cleavable complexes in lovocells and ht-29 cell lines with the ic50 of 15.8 μm and 5.17 μm, respectively [1].after addition of 157 mm irinotecan to plasma, sn-38 concentration showed linear increase during the first 60-min period, followed by a plateau.in the first 60 min, mean and standard deviation of the conversion rate were 515.9 ± 50.1 pmol/ml/h (n = 69), with a coefficient of variation of 0.097 [2]. irinotecan (cpt-11) was significantly more active in sclc than in nsclccelllines (p = 0.0036). ce activity appeared to be associated with higher sensitivity to cpt-11 in human lung cancercelllines and may partly explain the difference in the in vitro sensitivity to cpt-11 between sclc and nsclccells [3].in vitro, the sensitivity to cpt-11 and sn-38 was highest in ls174t and colo 320cells, intermediate in sw1398cellsand lowest in colo 205 and widr cells. the activity of sn-38 was 130 to 570 times than cpt-11[4]. | | in vivo | in colo 320 xenografts, irinotecan induced a maximum growth inhibition of 92% [4].a single dose of irinotecan significantly increased amounts of topoisomerase i covalently bound to dna in stomach, duodenum, colon and liver. concomitantly, the irinotecan-treated group exihibited significantly higher amounts of dna strand breaks in colon mucosa cells compared to the control group [5]. | | references | [1]. tobin p, clarke s, seale j p, et al. the in vitro metabolism of irinotecan (cpt‐11) by carboxylesterase and β‐glucuronidase in human colorectal tumours[j]. british journal of clinical pharmacology, 2006, 62(1): 122-129.
