Chemical modification of curdlan to induce an interaction with poly(C)(1)
K Koumoto, T Kimura, H Kobayashi, K Sakurai, S Shinkai
CHEMISTRY LETTERS ( 9 ) 908 - 909 2001.9
Publisher:CHEMICAL SOC JAPAN
The molecular weight of the commercially available curdlan is over 10(6), which makes it difficult to bind to polynucleotides. This paper presents a chain-scission reaction of curdlan and the molecular weight dependence of the binding ability. We found that curdlan can bind to poly(C) when the molecular weight is less than about 10(5). However, the complex stability is still less than that of the single chain of schizophyllan.

Organization of nucleosides supported by boronic-acid-appended poly(L-lysine): Creation of a novel RNA mimic
H Kobayashi, M Amaike, K Koumoto, S Shinkai
BULLETIN OF THE CHEMICAL SOCIETY OF JAPAN 74 ( 7 ) 1311 - 1317 2001.7
Publisher:CHEMICAL SOC JAPAN
Boronic-acid-appended poly(L-lysine) (1) can form anionic boronate esters with diol derivatives in aqueous solution. One can thus expect that when nucleosides are mixed with 1, the resultant complexes will satisfy the basic structural characteristics of RNA, viz., one-dimensionally organized nucleic bases and anionic charges. To obtain insights into this novel RNA mimic, the solution properties of adenosine (Ad) were estimated in the absence and the presence of 1. The large absorption and CD spectral changes were observed at pH 6-10 where the poly(L-lysine) main chain tends to adopt an a-helix-rich conformation. On the basis of the fact that the magnitude of the spectral changes is much larger than the fraction of complexed Ad molecules, the polymer-supported organization mode was proposed: that is, Ad molecules complexed by covalent bonds with I act as clusters to induce further organization of uncomplexed Ad molecules by noncovalent interactions. The proposal was further confirmed by H-1 NMR spectroscopy and dynamic light scattering, On the other hand, none of these spectral changes were observed for 2 ' -deoxyadenosine. The I-Ad complex thus formed can interact with complementary poly(U) but not with noncomplementary poly(C), indicating that it can act as a novel RNA mimic.

Polysaccharide-polynucleotide complexes (IV): Antihydrolysis effect of the schizophyllan/poly(C) complex and the complex dissociation induced by amines
K Koumoto, T Kimura, K Sakurai, S Shinkai
BIOORGANIC CHEMISTRY 29 ( 3 ) 178 - 185 2001.6
Publisher:ACADEMIC PRESS INC
Polymer complexes formed by schizophyllan and poly(C) showed a unique antihydrolysis effect when poly(C) was subjected to hydrolysis under basic conditions. The complexation reduced the hydrolysis rate to 80% of the control (i.e., poly(C) itself). However, when we added oligoamines with the intention of catalyzing the hydrolysis, the oligoamines induced dissociation of the complex instead of acceleration of the hydrolysis.

TEM and SEM observations of super-structures constructed in organogel systems from a combination of boronic-acid-appended bola-amphiphiles with chiral diols
K Koumoto, T Yamashita, T Kimura, R Luboradzki, S Shinkai
NANOTECHNOLOGY 12 ( 1 ) 25 - 31 2001.3
Publisher:IOP PUBLISHING LTD
Two bola-amphiphilic alpha, omega -diboronic acids separated by a (CH(2))(11) or (CH(2))(12) group were synthesized. Complexation with chiral diols readily gave new amphiphiles end-capped with the chiral substituents. Some of these acted as good gelators of organic solvents. Transmission electron microscope and scanning electron microscope observations established that a variety of super-structures are created in the organogels, depending on the solvents and the structure of the chiral end-cap groups. In most cases, the fibrous aggregates, the network structure which is the driving-force for gelation, showed a helical higher-order structure reflecting the chirality of the end-cap groups. The results indicate that the combinatorial approach utilizing boronic acid functions and diol compounds is useful in creating a variety of new super-structures in the gel phase.
