APHIDICOLIN.

Aphidicolin is an inhibitor of DNA polymerase α and δ, prevents mitotic cell division by interfering with the activity of DNA polymerase[1].Aphidicolin is an antibiotic produced by the mold Cephalosporium aphidicola. Aphidicolin is a potent inhibitor of cellular deoxyribonucleic acid synthesis and inhibits the growth of herpes simplex virus[2].Aphidicolin potentiates apoptosis induced by arabinosyl nucleosides in a human promyelocytic leukemia cell line[3].
Aphidicolin is a tetracyclic diterpenoid that has an tetradecahydro-8,11a-methanocyclohepta[a]naphthalene skeleton with two hydroxymethyl substituents at positions 4 and 9, two methyl substituents at positions 4 and 11b and two hydroxy substituents at positions 3 and 9. An antibiotic with antiviral and antimitotical properties. Aphidicolin is a reversible inhibitor of eukaryotic nuclear DNA replication. It has a role as an antimicrobial agent, an antiviral drug, an antineoplastic agent, an EC 2.7.7.7 (DNA-directed DNA polymerase) inhibitor, a DNA synthesis inhibitor, an apoptosis inducer, a fungal metabolite, an Aspergillus metabolite and an antimitotic.|An antiviral antibiotic produced by Cephalosporium aphidicola and other fungi. It inhibits the growth of eukaryotic cells and certain animal viruses by selectively inhibiting the cellular replication of DNA polymerase II or the viral-induced DNA polymerases. The drug may be useful for controlling excessive cell proliferation in patients with cancer, psoriasis or other dermatitis with little or no adverse effect upon non-multiplying cells.
