Camptothecin: A Promising Anticancer Drug
Camptothecin is a natural alkaloid derived from the Chinese tree Camptotheca acuminata. It has been studied extensively as a potential anticancer agent due to its ability to inhibit topoisomerase I, an enzyme crucial for DNA replication.
Mechanism of Action
Camptothecin and its derivatives work by trapping topoisomerase I in a complex with DNA, preventing the enzyme from completing its
function. This leads to DNA damage and cell death.
