Specifications

Aphidicolin is a tetracyclic diterpene antibiotic isolated from species in several genera of fungi, notably Cephalosporium, Nigrospora, Harziella and Phoma. Aphidicolin has antibiotic, antiviral and antimitotic properties blocking the cell cycle at early S-phase. This property has been used to synchronize cell division and has found use as a tool in cell differentiation research. Aphidicolin is a reversible inhibitor of DNA replication by inhibition of selected DNA polymerases. Aphidicolin induces apoptosis, prolongs the half-life of DNA methyltransferase, is active against Leishmania parasites and acts synergistically with the antitumor agents, vincristine and doxorubicin.
