    Synthesis and Biological Activities of Topopyrones
    摘要:
    Structure-activity studies were employed to investigate the stabilization of DNA-topoisomerases I and II covalent binary complexes by topopyrone analogues. The synthesis of five new topopyrone derivatives and study of their ability to stabilize DNA topoisomerase I and DNA-topoisomerase II covalent binary complexes are described. The biochemical assays suggest that the orientation of the fused 1,4-pyrone ring and halogen substituents contribute importantly to the overall potency of the topopyrones as topoisomerase poisons.

An alternative selective synthetic route to 3-ethyl-2-hydroxy-5,7,8-trimethoxy-6-methyl-1,4-naphthoquinone was also developed utilizing an intramolecular Claisen condensation of methyl 2-butyryl-3,5,6-trimethoxy-4-methylphenylacetate with concomitant in situ aerial oxidation.
