    Description: 4,9-Dihydroxy-alpha-lapachone has antitumor-promoting effects, it exhibits significant inhibitory activity against 12-O-tetradecanoylphorbol 13-acetate (TPA)-induced Epstein-Barr virus early antigen (EBV-EA) activation in Raji cells. 4,9-Dihydroxy-alpha-lapachone exhibits potent inhibitory effects on lipopolysaccharide-induced NO synthesis in RAW 264.7 cells , with IC(50) value of 2.73 microM.
    Targets: NO

    Naphthoquinones from Catalpa ovata and their inhibitory effects on the production of nitric oxide.[Pubmed: 20361302]

    METHODS AND RESULTS:
    Together with nine known compounds, catalponol (1), catalponone (2), catalpalactone (3), alpha-lapachone (4), 9-hydroxy-alpha-lapachone (5), 4,9-Dihydroxy-alpha-lapachone (6), 9-methoxy-alpha-lapachone (7), 4-oxo-alpha-lapachone (8), and 9-methoxy-4-oxo-alpha-lapachone (9). The structures were elucidated on the basis of spectroscopic analyses. The inhibitory effects of these isolates on lipopolysaccharide-induced NO synthesis in RAW 264.7 cells were evaluated.
    CONCLUSIONS:
    Among them, catapalactone (3), 9-hydroxy-alpha-lapachone (5) and 4,9-Dihydroxy-alpha-lapachone (6) exhibited potent inhibitory effects, with IC(50) values of 9.80, 4.64 and 2.73 microM, respectively.
