  Photobleaching Activity of 2-(Phenylamino)methylidenecyclohexane-1,3-diones in Tobacco (Nicotiana tabacum) Cultured Cells

  摘要：

  A series of phenylalkylidenecyclohexane-1,3-dione derivatives were designed and synthesized as vinylogous analogs of phthalimides, which are known photobleaching herbicides. The bleaching activity of synthesized compounds was assayed with photomixotrophic tobacco cultured cells under either light or dark conditions. Both the chlorophyll and the carotenoid contents of the cells treated with the cyclic diones decreased to almost zero within 24 h under the light condition but not under the dark condition. This rapid emergence of bleaching activity with light is one of the most distinctive actions of Protox-inhibiting herbicides; however, the cyclic dione did not inhibit protoporphyrinogen oxidase in vitro. Thus, we concluded that the cyclic diones possessed a different herbicidal mode of action from Protox-inhibiting herbicide.
