V. Cucinotta et al., 3-DIMENSIONAL CYCLODEXTRIN - A NEW CLASS OF HOSTS BY TREHALOSE CAPPING OF BETA-CYCLODEXTRIN, Journal of inclusion phenomena and molecular recognition in chemistry, 25(1-3), 1996, pp. 39-42
In order to obtain better abiotic receptors for analytical and kinetic
applications, the new capped derivative of cyclomaltoheptaose (CDTH)
was synthesized by reaction of deoxy-6,6'-di(S-cysteamine)-alpha,alpha
'-trehalose with 6A,6D-dideoxy-6A,6D-diiodo-cyclo-maltoheptaose. The C
DTH-ACS (anthraquinone-2-sulfonic acid sodium salt) system was investi
gated. by H-1 NMR spectroscopy and by i.c.d. (induced circular dicrois
m), and a deep inclusion of ACS inside the CDTH cavity, with an associ
ation constant about six times larger with respect to ACS - beta-CD sy
stem was found.
