    摘要: The present invention relates to the field of drug carrier systems and polymer therapeutics and diagnostics. It provides derivatized unimolecular polyols with a hydrophobic core moiety and a polyanionic, preferably, sulfated hydrophilic shell, in particular to unimolecular hyperbranched sulfated polyglycerol micelles having a hydrophilic shell and a hydophobic core. These may be used for the supramolecular encapsulation and transport of hydrophobic guest molecules into biological systems. The micelles can be applied as a drug carrier system for therapy and for diagnosis. They may also be therapeutic agents on their own. The invention also relates to preparation of said micelles.

    摘要: Hydrogels that degrade under appropriate conditions of pH and temperature by virtue of crosslinking compounds that cleave through an elimination reaction are described. The hydrogels may be used for delivery of various agents, such as pharmaceuticals. This invention provides hydrogels that degrade to smaller, soluble components in a non-enzymatic process upon exposure to physiological conditions and to methods to prepare them. The hydrogels are prepared from crosslinking agents that undergo elimination reactions under physiological conditions, thus cleaving the crosslinking agent from the backbone of the hydrogel. The invention also relates to the crosslinking agents themselves and intermediates in forming the hydro gels of the invention. The biodegradable hydro gels prepared according to the methods of the invention may be of use in diverse fields, including biomedical engineering, absorbent materials, and as carriers for drug delivery.
