Camptothecin and its molecular structure shown in Figure

      Camptothecin (called CPT for short) is a cytotoxic natural alkaloid, The first time in 1966, the Wall and others separated it from involucrata plants Camptotheca acuminata of the rod and the skin. Continuous molecular structure of conjugated rings, containing a pyrrolo [3,4-b] quinoline ring (ring A, B, C), a conjugate of α-pyridone ring (ring D) and a six α-hydroxy lactone ring (ring E), the only chiral molecule C20 to S-type.
