Starch-derived clathrate-forming compositions
Embodiments of the present disclosure relate to materials and methods for preparing a clathrate-forming composition comprising a plurality of linear glucomonomer chains of about 15 to about 100 D-glucopyranosyl residues linked by α-1,4 linkages, wherein the linear glucomonomer chains are a product of partial amylolysis of a modified starch substrate and wherein the product is flowable at temperatures within a range of 4-20° C. at about 20% w/v solids content. The present disclosure further describes methods of using the clathrate-forming compositions to form molecular dispersions or clathrates with hydrophobic guest molecules, kits for use in these methods, and molecular dispersions or clathrates obtained from the materials.
CROSS-LINKING COMPOUNDS AND METHODS OF USE THEREOF
Compounds comprising a cross-linking moiety and a protecting group are described herein along with their methods of use. The cross-linking moiety may comprise an indoxyl and the protecting group may comprise a sugar (e.g., a glucuronide or glucoside), phosphoester, or sulfoester group. The cross-linking moiety and protecting group may be attached to each other via an oxygen atom, sulfur atom, or linker. In some embodiments, the linker attaching the cross-linking moiety and protecting group is a self-immolative linker. A compound of the present invention may cross-link under physiological conditions and/or in vivo.

Method of synthesising 6-deoxy-6-amino-β-D-glucopyranoside-containing polymers and their precursors
The invention provides an improved method of synthesising derivatives of β-D-glucopyranoside-containing polymers, such as chitin, chitosan, cellulose, amylose, pullulan, curdlan, inulin, guar gum or cyclodextrin. The method includes reacting a polymer of formula (III) with a cyclic imide to form a polymer of formula (I) thereby introducing a nitrogen functionality at the 6-position and providing access to 6-deoxy-6-amino-β-D-glucopyranoside-containing polymers. ##STR00001##
