Aphidicolin, a tetracyclic diterpenoid, is an antibiotic with novel structure produced by the mold Cephalosporium aphidicola. Aphidicolin is an inhibitor of DNA polymerase-α .
DNA polymerase-α is an enzyme complex involved in initiation of DNA replication and during synthesis of Okazaki fragments on the lagging strand. The DNA polymerase-α complex consists of 4 subunits: POLA1, POLA2, PRIM1, and PRIM2. POLA1 is the catalytic subunit. POLA2 is the regulatory subunit. PRIM1 and PRIM2 are the small and the large primase subunits .
Aphidicolin selectively inhibited the activity of DNA polymerase-α without activity for DNA polymerase-β and mitochondrial DNA polymerase. Aphidicolin prevented cell division in sea urchin embryos . Aphidicolin was a potent inhibitor of cellular deoxyribonucleic acid synthesis. Aphidicolin strongly inhibited the growth of herpes simplex virus both in tissue culture and in the rabbit eye. Aphidicolin was active against iododeoxyuridine-resistant herpes virus . Aphidicolin showed antiviral activity and inhibited the incorporation of thymidine into DNA of cultured human embryonic lung cells. Aphidicolin (15 μg/ml) reduced the activity of crude and partially purified DNA polymerases from the cytosol .
