Epolactaene, a neuritogenic compound in human neuroblastoma cells, showed inhibitory activities against DNA polymerases alpha and beta. The synthesis and inhibitory activities of epolactaene analogs are described. The alpha,beta-epoxy-gamma-lactam moiety in the core and the length of the side chain greatly influenced the activities. Compound 5 was the strongest inhibitor of DNA polymerase a and 0 of all synthesized compounds with IC50 values of 13 and 78 muM, respectively. N- and O-alkyl derivatives that had modified core moieties showed moderate inhibition. (C) 2004 Elsevier Ltd. All rights reserved.
