Topotecan hydrochloride, Tocris Bioscience™

Description

DNA topoisomerase I inhibitor; Camptothecin (Cat. No. 1100) analog

Topotecan hydrochloride is a DNA topoisomerase I inhibitor; induces rapid apoptotic death in human B-lineage acute lymphoblastic leukemia (ALL) cells. Improves survival in three mouse models of poor prognosis ALL; downregulates B-Myb and MycN expression in neuroblastoma cells. Water-soluble analog of Camptothecin (Cat. No. 1100). Orally bioavailable. Topotecan disrupts the interaction between NHP2L1 and U4 RNA by binding to U4 and inhibits RNA splicing.
