Fluorescence study on the nyctinasty of Cassia mimosoides L. using novel fluorescence-labeled probe compounds

We synthesized fluorescence-labeled probe compounds bearing 6-((7-amino-4-methylcoumarin-3-acetyl)amino)-hexanoyl (AMCA, 1), 6-N-(7-nitrobenz-2-oxa-1, 3-diazol-4-yl)-aminohexanoyl (NBD, 2), and 6-(4-((5-dimethylaminonaphthalene-1-sulfonyl)-amino))-hexanoyl (dansyl, 3) groups as the fluorescent functionality. In these probe compounds, NBD-type probe, 2, showed leaf-opening activity at 5×10-6 M. The bioactivity of 2 is one-fifth as strong as that of the natural product, potassium isolespedezate (6). We carried out the binding experiment using 1 in a plant body. Then, it was suggested that fluorescence-labeled probe compound directly bound to a motor cell in pulvina of Cassia mimosoides. And this binding was specific to C. mimosoides. Probe compounds cannot bind plant sections of other nyctinastic plants.

Syntheses of fluorescence-labeled artificial leaf-opening substances, fluorescent probe compounds useful for bioorganic studies of nyctinasty

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 galactoisolespedezates (3, 10, 13), designed on the basis of 1 and 2, were prepared. In particular, compound 3 was bioactive at 5 x 10-5 M, one-fiftieth as strong as the natural leaf- opening substance. This fluorescent probe would be useful for bioorganic studies of nyctinasty.

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.
