Camptotheca acuminata
Arbre chinois à croissance rapide source de camptothécine, la base de plusieurs médicaments chimiothérapeutiques anticancéreux.
Camptotheca acuminata is a fast-growing Chinese tree that produces camptothecin, a potent topoisomerase I inhibitor that serves as the precursor for the anticancer drugs irinotecan and topotecan. While traditionally used in Chinese medicine for digestive cancers and psoriasis, the raw plant material is highly toxic and requires pharmaceutical processing for safe use.
Camptothecin and its derivatives act as topoisomerase I inhibitors, stabilizing the topoisomerase I-DNA cleavage complex and preventing DNA religation, leading to replication fork collision and double-strand breaks. This mechanism selectively targets rapidly dividing cancer cells. Additionally, 10-hydroxycamptothecin and other alkaloids may contribute to anti-inflammatory and antiviral effects through inhibition of NF-κB and viral replication pathways.
