    摘要: Polymeric reagents comprising a polymer attached, either directly or through one or more atoms, to a ketone or a related functional group such as ketone hydrate, thione, monothiohydrate, dithiohydrate, hemiketal, monothiohemiketal, dithiohemiketal, ketal, or dithioketal are provided. The polymeric reagents are useful for, among other things, forming polymer-active agent conjugates. Related methods, compositions, preparations, and so forth are also provided.

    摘要: Provided herein are polymeric α-hydroxy aldehyde or α-hydroxy ketone reagents which can be conjugated to amine-containing compounds to form stable conjugates in a single-step reaction. In selected embodiments, the polymeric reagent itself incorporates an internal proton-abstracting (basic) functional group, to promote more efficient reaction. The substituent is appropriately situated, via a linker if necessary, to position the group for proton abstraction, preferably providing a 4- or 5-bond spacing between the abstracting atom and the hydrogen atom on the α-carbon. Also provided are methods of using the reagents and stable, solubilized conjugates of the reagents with biologically active compounds. In preferred embodiments, the polymeric component of the reagent or conjugate is a polyethylene glycol.

    摘要: Segmented water soluble polymers, containing a higher molecular weight segment linked to a lower molecular weight segment, are described. In one embodiment, the polymer segments are poly(ethylene glycol) segments. The segmented polymers are functionalized and are useful for conjugation to various moieties such as pharmacologically active substances. Also described are conjugates of such polymers and methods of their preparation.
