应用
盐酸伊立替康用于：:
- 与5-氟尿嘧啶联合使用，在MDA-MB-231乳腺癌细胞中筛选生长抑制功能。
- 在高级别阑尾癌（HGA）和低级别阑尾癌（LGA）中筛选化学敏感性。
- 作为化学治疗剂，与热休克蛋白抑制剂（HPSC1）联合使用，研究对HT29结肠癌细胞的细胞毒性。
生化/生理作用
抗癌药伊立替康是一种前药，在组织羧酸酯酶作用下转化为7-乙基-10-羟基喜树碱（SN-38）——一种有效的DNA拓扑异构酶I抑制剂。通过UDP葡萄糖醛酸转移酶1A1（UGT1A1）的葡萄糖醛酸化作用，可终止该药的作用。该药物能增强组织对辐射损伤的敏感性，因此可用于肿瘤的放射治疗。

Irinotecan is a topoisomerase-I (Top-I) inhibitor used for the treatment of colorectal cancer. DNA demethylating agents, including 5-azacytidine (5-aza), display synergistic antitumor activity with several chemotherapy drugs. 5-Aza may enhance irinotecan cytotoxicity by at least one of the following mechanisms:

Testing of drug effects and cytotoxicity by using cultured cells has been widely performed as an alternative to animal testing. However, the estimation of pharmacokinetics by conventional cell-based assay methods is difficult because of the inability to evaluate multiorgan effects.
