A method and a device for obtaining electric energy efficiently from a hydrous organic substance by suppressing the activation overvoltage of an anode low and thereby obtaining a sufficiently low anode potential. The power generating device comprises an anaerobic region (4) including microorganisms which can grow under anaerobic conditions, solution or suspension containing an organic substance, an electron mediator and an anode (1), an aerobic region (5) including molecular oxygen and a cathode (3), and a diaphragm (2) defining the anaerobic region (4) and the aerobic region (5), wherein a closed circuit (6) is formed by connecting the anode (1) and the cathode (3) electrically with a power utilization apparatus, and oxidation reaction of microorganisms using the organic substance in the anaerobic region (4) as electron donor and a reduction reaction using oxygen in the aerobic region (5) as electron acceptor are utilized. The anode (1) includes a conductive substrate having a surface coated at least partly with a hydrophilic polymer layer, an electron mediator is introduced into the hydrophilic polymer layer with chemical bond, and the anode (1) has a standard electrode potential (E0') at pH 7 in a range of -0.13 V to -0.28 V.

A highly efficient synthesis of naphthoquinones containing amino, hydroxy and alkyl groups was created, which provided new insights into the synthetic methodologies for various derivatives with diverse substitutions. Among them, derivatives carrying a methyl group at C‐2 and hydroxyl/amino group at C‐5 have exerted high antiproliferative activities and low toxicities in vitro.
