Application

7-Ethyl-10-hydroxycamptothecin has been used:
  • to inhibit enterovirus 71 (EV71) (H) infection
  • to screen the chemosensitivity of pancreatic adenocarcinoma cells
  • as a chemical to study its ability to reverse multidrug resistance (MDR), due to ATP binding cassette (ABC) transporters

Biochem/physiol Actions

Active metabolite of irinotecan. Inhibitor of topoisomerase I.. Gene expression analysis of colon cancer cell lines treated with SN-38 showed differential effects: the majority of affected genes were down-regulated (including, most strongly, genes related to receptor and kinase activity, signal transduction, apoptosis, RNA processing, protein metabolism and transport, cell cycle and transcription. Some of the up-regulated genes were involved in apoptosis, transcription, development and differentiation.

Recent studies indicate that chemotherapeutic agents may increase the anti-tumoral immune response. Based on the pivotal role of dendritic cells (DCs) in host tumour-specific immune responses, we investigated the effect of commonly used chemotherapeutic drugs dexamethasone, doxorubicin, cisplatin and irinotecan
