Description

Biochem/physiol Actions

(S)-(+)-Camptothecin binds irreversibly to the DNA-topoisomerase I complex, inhibiting the reassociation of DNA after cleavage by topoisomerase I and traps the enzyme in a covalent linkage with DNA. The enzyme complex is ubiquinated and destroyed by the 26S proteasome, thus depleting cellular topoisomerase I. Blocks the cell cycle in S-phase at low does and induces apoptosis in a large number of normal and tumor cell lines by cell cycle-dependent and cell cycle-independent processes.
