| Photosystem II Inhibition by Pyran-enamine Derivatives  | | | | Abstract
| Through the studies on structure-activity relationships o f 5-acyl-3-(l-am inoalkylidene)-4-hydroxy-2 H-pyran-2,6(3 H)-dione derivatives in photosystem II (PS II) inhibition, overall lipophilicity o f the m olecule was found to be a major determinant for the activity. In the sub stituted N -benzyl derivatives, not only the lipophilicity but also the electronic and steric char acters o f the substituents greatly affected the activity. Their mode o f PS II inhibition seemed to be similar to that o f D C M U , whereas pyran-enamine derivatives needed to be highly lipophilic to block the electron transport in thylakoid membranes, which in turn diminished the permea bility through biomembranes. | | | |
