Visualization of the precise structure recognition of leaf-opening substance by using biologically inactive probe compounds: Fluorescence studies of nyctinasty in legumes 2

Intimate correlation between bioactivity and binding activity was shown using biologically active and inactive fluorescence-labeled probe compounds for nyctinasty. This results suggested the existence of a receptor which recognizes the aglycon of a leaf-o

Synthetic probe compounds for bioorganic studies of nyctinasty, based on the leaf-opening substance of Lespedeza cuneata G. Don

In a previous paper, the syntheses of potassium galactolespedezate (1) and potassium galactoisolespedezate (2), artificial leaf-opening substances useful for bioorganic studies of nyctinasty were reported. The fluorescent probe compounds, fluorescence-labeled galactoisolespedezate (3) and iodo-one (4), designed on the basis of 1 and 2 were prepared. Especially, compound 3 was bioactive at 5x10-5 M, one-fiftieth as strong as the natural leaf-opening substance. This fluorescent probe would be useful for bioorganic studies of nyctinasty.
