High TOP1 enzymatic activity MCF7 (Luminal subtype) and HCC1419 (HER2 subtype) show high sensitivity toward Camptothecin (0.1 μM to 5 μM; 72 hours) treatment, exhibiting the IC50 values of 0.089 μM and 0.067 μM, respectively[4].
Camptothecin (0.5 μM; 6 and 24 hours) reduces desferrioxamine-activated VEGF expression.
Camptothecin (0.5 μM; 8 to 24 hours) strongly prevents the desferrioxamine-dependent HIF-1a accumulation[2].

Sodium Camptothecin is a plant alkaloid, with antitumor activity. Sodium Camptothecin is a reversible inhibitor of RNA synthesis. Sodium Camptothecin is an effective inhibitor of adenovirus replication. Sodium Camptothecin inhibits DNA synthesis and causes breaks in intracellular preformed viral DNA[1][2].
