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, intracellularly, causes breaks in preformed viral DNA[1][2].

In Vitro	Sodium Camptothecin (5 μM; 10 min) causes a severe inhibition of heterogeneously sedimenting nuclear RNA (HnRNA) synthesis[1]. Sodium Camptothecin also blocks a specific step in the processing of ribosomal precursor RNA, allowing the conversion of 45S RNA to 32S RNA, but inhibiting the conversion of 32S RNA to 28S RNA [1].
