General description

Aphidicolin is a tetracyclic diterpene with antiviral and antimitotic properties used for cell cycle synchronization in various cell lines.


Aphidicolin, from Nigrospora sphaerica, was used for cell cycle synchronization of tobacco BY-2 cells. It is used to block the entry of cells into S-phase.

Biochem/physiol Actions

Aphidicolin specifically inhibits DNA polymerase α that is responsible for DNA replication. It also inhibits α-like DNA polymerases of plants and yeasts but does not inhibit synthesis of RNA and proteins. Aphidicolin competes for the dCTP-specific binding site on DNA polymerase α specifically. Aphidicolin has antiviral and antimitotic properties. It blocks the cell cycle at S phase. It has been shown to induce apoptosis in HeLa cells.
