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.

Sulfone linkers which couple drugs to carriers of various types are described. These linkers permit the release of the drug over time in a controlled manner. The release occurs through beta-elimination, and does not require enzymatic cleavage. Products of the linkers with both drugs and macromolecules and methods of using them are described as well.
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.
The invention relates to conjugates of macromolecular carriers and drugs comprising linkers that release the drug or a prodrug through rate-controlled beta-elimination, and methods of making and using the conjugates.
The invention relates to compositions that comprise dendrimers useful in medical and veterinary applications that provide controlled release of drugs, such as peptides, nucleic acids and small molecules. The drugs are covalently coupled to the dendrimer through a linkage that releases the drug or a prodrug through controlled beta elimination.
