Abstract: The present invention provides conjugates and methods of using the same for the treatment of cerebral, meningeal, and neural diseases, disorders, and conditions. Provided methods include administering conjugates directly into the cerebrospinal fluid space of an animal.

Abstract: The present invention relates to conjugate comprising a carrier substituted with one or more occurrences of a moiety having the structure: wherein each occurrence of M is independently a modifier having a molecular weight ?10 kDa; denotes direct of indirect attachment of M to linker LM; and each occurrence of LM is independently an optionally substituted succinamide-containing linker, whereby the modifier M is directly or indirectly attached to the succinamide linker through an amide bond, and the carrier is linked directly or indirectly to each occurrence of the succinamide linker through an ester bond. In another aspect, the invention provides compositions comprising the conjugates, methods for their preparation, and methods of use thereof in the treatment of various disorder, including, but not limited to cancer.

Abstract: The present invention relates to biodegradable biocompatible polyketals, methods for their preparation, and methods for treating animals by administration of biodegradable biocompatible polyketals. In one aspect, a method for forming the biodegradable biocompatible polyketals comprises combining a glycol-specific oxidizing agent with a polysaccharide to form an aldehyde intermediate, which is combined with a reducing agent to form the biodegradable biocompatible polyketal. The resultant biodegradable biocompatible polyketals can be chemically modified to incorporate additional hydrophilic moieties. A method for treating animals includes the administration of the biodegradable biocompatible polyketal in which biologically active compounds or diagnostic labels can be disposed. The present invention also relates to chiral polyketals, methods for their preparation, and methods for use in chromatographic applications, specifically in chiral separations.
