Abstract

The synthesis naphthoquinones exhibited stronger activity than the pyranonaphthoquinone-type compound having moderate inhibitory activity against Cdc25A protein phosphatase. The novel naphthalene-type analogues 14 and 18 and the naphthoquinone-type analogues, 8, 9, 15, 16, 19, 21, 22, and 23-28 have been synthesized, and their in vitro Cdc25A phosphatase-inhibitory activity was examined. In assessment of the inhibitory activity, it was revealed that the naphthoquinone core is contributed to the activity, rather than the alkyl side chain.
