Background |
Irinotecan is a topoisomerase I inhibitor that prevents religation of DNA strands by binding to the topoisomerase I-DNA complex. |
Biological Activity |
Irinotecan是水溶性的拓扑异构酶I抑制剂,通过与拓扑异构酶I-DNA复合物结合来防止DNA链的再连接。[1-5] |
In Vitro |
伊立替康是拓扑异构酶I抑制剂。伊立替康抑制LoVo和HT-29细胞的生长,IC50分别为15.8±5.1和5.17±1.4μM,并且在LoVo和HT-29细胞中诱导相似量的可切割复合物[2]。伊立替康抑制人脐静脉内皮细胞(HUVEC)的增殖,IC50为1.3μM[3]。 |
In Vivo |
伊立替康(CPT-11,5mg / kg)在大鼠中连续两周每天通过肿瘤内注射显着抑制肿瘤的生长,并且这种效果也通过渗透微型泵连续腹膜内输注进入小鼠而发生。然而,伊立替康(10 mg / kg)对ip的生长没有影响[1]。伊立替康(CPT-11,100-300mg / kg,ip)显然在第21天抑制无胸腺雌性小鼠中HT-29异种移植物的肿瘤生长。两组伊立替康(125mg / kg)加TSP-1(10mg)/ kg /天或伊立替康(150 mg / kg)联合使用TSP-1(每天20 mg / kg)几乎同样有效,分别抑制肿瘤生长84%和89%,两者均比单独使用伊立替康更有效剂量为250和300毫克/千克[3]。 |
Cell Experiment |
将指数生长的细胞接种在20cm 2培养皿中,每个细胞系具有最佳细胞数(对于LoVo细胞为20,000,对于HT-29细胞为100,000)。 2天后,用增加浓度的伊立替康或SN-38处理它们一个细胞倍增时间(LoVo细胞24小时,HT-29细胞40小时)。用0.15M NaCl洗涤后,细胞在正常培养基中进一步生长两次,用胰蛋白酶-EDTA从支持物上分离,并在血细胞计数器中计数。然后将IC50值估计为与不用药物孵育的细胞相比,负责50%生长抑制的药物浓度[2]。 |
Animal Experiment |
伊立替康通过瘤内注射0.1cc体积的适当溶液给药,连续两周每天5mg / kg,连续两周,然后休息7天,称为一个治疗周期。大鼠在8周的时间内接受三个周期。对照动物通过瘤内注射以与第II组动物相同的给药规则接受0.1cc无菌0.9%氯化钠溶液[1]。 |
