Polysaccharide-polynucleotide complexes (III): A novel interaction between the beta-1,3-glucan family and the single-stranded RNA poly(C)

T Kimura, K Koumoto, K Sakurai, S Shinkai

Publisher：CHEMICAL SOC JAPAN

We measured circular dichroism spectra to examine the complex-formation capability of various kinds of polysaccharides with poly(C). The results show that schizophyllan and lentinan can interact with poly(C), on the other hand, amylose, pullulan, dextran, and curdlan cannot. This difference clearly indicates that the water soluble beta -1,3-glucan can bind with polynucleotides. The molecular weight dependence of the complex formation has established that at least 30 glucose sequence length is necessary to incorporate the most bases into the complex.

Colorimetric sugar sensing method useful in "neutral" aqueous media

K Koumoto, S Shinkai

CHEMISTRY LETTERS ( 8 ) 856 - 857 2000.8

Publisher：CHEMICAL SOC JAPAN

Azobenzene derivatives bearing one or two aminomethylphenylboronic acid groups were synthesized: they were confirmed to be useful for practical colorimetric saccharide sensing in "neutral" aqueous media.

The first example of positive allosterism in an aqueous saccharide-binding system designed on a Ce(IV) bis(porphyrinate) double decker scaffold

The first example of a positive, homotropic system in aqueous saccharide-binding has been achieved using a Ce(IV) bis(porphyrinate) double decker scaffold bearing two pairs of boronic acid groups (compound 2). In this system, the binding of the first guest (1:2 saccharide/boronic acid complex) suppresses the rotational freedom of the two porphyrin planes, which facilitates the binding of the second guest. As a result, two pairs of boronic acid groups in 2 can autoacceleratively bind these guests and yield CD-active species. The analyses of CD intensity-guest concentration plots according to the Hill equation resulted in K=3.7x10(4) M-2 and n=2.0 for D-fructose and K=9.6x10(5) M-2 and n=1.6 for D-glucose. The present system which is in action even in aqueous media is widely applicable to allosteric control of drug release, catalytic reaction, information transduction, etc. of saccharide-containing guest molecules.
