    Camptothecin showed remarkable anticancer activity in preliminary clinical trials by inhibiting the DNa enzyme topoisomerase I (topo I). (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.

    Natural origins of camptothecin:
    1. Camptotheca acuminata (Camptotheca, Happy tree), a tree native to Hunan ,Guangxi, Sichuan province of China. Camptotheca acuminata used as a cancer treatment in Traditional Chinese Medicine.Generally, the leaves and the fruits of happy tree are applied for the extraction of camptothecin.
    2. Nothapodytes pittosporoides(Mappia), a tree wild spread in Hunan ,Guangxi, Sichuan province of China. The root of the tree is applied for the extraction of campothecin, most of this origin is applied for R&D.
