SN-38 (Synonyms: NK012)
SN-38 (NK012) 是拓?fù)洚悩?gòu)酶 I (Topoisomerase I) 抑制劑伊立替康的活性代謝產(chǎn)物。SN-38 (NK012) 抑制 DNA 合成和 RNA 合成的 IC50 分別為 0.077 和 1.3 μM。
生物活性
SN-38 (NK012) is an active metabolite of the Topoisomerase I inhibitor Irinotecan. SN-38 (NK012) inhibits DNA and RNA synthesis with IC50s of 0.077 and 1.3 μM, respectively
IC50 & Target
Topoisomerase I
Camptothecins
體外研究(In Vitro)
The IC50 values for LoVo, HCT116, and HT29 cell lines is 20 nM, 50 nM, 130 nM, respectively. In all three SN-38 (NK012) resistant cell lines Top1 activity is maintained in the presence of high concentrations of SN-38[2].
體內(nèi)研究(In Vivo)
SN-38 (NK012), the active and toxic metabolite of the anticancer prodrug Irinotecan. At 30 minutes after administration, Irinotecan plasma concentrations in Slco1a/1b(?/?) mice are 1.9-fold higher than in the wild-type mice (1.89 vs. 1.01 μM, respectively), whereas SN-38 (NK012) plasma concentrations of Slco1a/1b(?/?) mice are 8-fold higher compare with wild-type mice (0.4 μg/mL vs. 0.05 μg/mL, respectively). Overall plasma exposure [AUC(5-240)] of Irinotecan is 1.7-fold higher in Oatp1a/1b knockout mice versus wild-type mice (209.8±6.7 vs. 120.9±4.4 μM/min; P<0.01), and 2.9-fold higher for SN-38 (50±2.9 vs. 12±2 μM/min; P<0.001)[3].
