Abstract

The 4-pyrone and 4-pyridone series were examined as a new type of photosynthetic inhibitor because of a structural resemblance to the co-enzyme plastoquinone, which lies between photosystem II and cytochrome b. These compounds inhibited a Hill reaction at 'the plastoquinone pool.'From our study of the structure/activity relationships for 4-pyrones and 4- pyridones, it has become clear that these compounds need no strict structural ...
