CONJUGATES HAVING A DEGRADABLE LINKAGE AND POLYMERIC REAGENTS USEFUL IN PREPARING SUCH CONJUGATES |
摘要 |
The present invention provides conjugates having a degradable linkage and polymeric reagents useful in preparing such conjugates. The conjugates as we ll as the polymeric reagents used to form the conjugates include at least one o f each the following: an aromatic moiety comprising an ionizable hydrogen atom , a spacer moiety, and a water-soluble polymer. Methods of making polymeric reagents and conjugates, as well as methods for administering conjugates and compositions, are also provided. |
