Five 8-aza-purine derivatives were examined on their ability to inhibit the growth of Hiochi-kin in purine-omitted synthetic medium. 8-azaguanine, 8-azaxanthine, or 8-azahypoxanthine inihibited the growth of strains T102 and T107 at a concentration of 2 μg/ml.8-aza-derivatives of adenine or isoguanine were less inhibitory. The inhibitition by high concentrations of 8-azaguanine was reversed by guanine, and 8-azaadenine was nullified in its inhibiting actioin by adding adenine. In synthetic medium containing ethanol, the antagonistic action of 8-azaguanine on guanine was less remarkable.In watered-Sake medium containing 10% ethanol, 8-azagaunine suppressed the growth of Hiochi-kin at a concentration of 100 μg/ml. The reversal evect by the components of Sake was recognized.
