inhibition of proteinkinaseC (PKC) by the natural product staurosporine has been used as a basis for the design of substituted bisindolylmaleimides with improved potency over the parent compound. Structure-activity relationships were consistent with the interaction of a cationic group in the inhibitor with a carboxylate group in the enzyme, and the most potent compound had a Ki of 3 nM. The inhibitors were

The invention provides polymer conjugates of protein kinase C (PKC) inhibitors comprising a polymer, such as poly(ethylene glycol), covalently attached to a PKC inhibitor, such as a bisindolylmaleimide molecule. The linkage between the polymer and the PKC inhibitor is preferably hydrolytically degradable. The invention also includes a pharmaceutical composition comprising a polymer conjugate of a PKC inhibitor and a method of treating any condition responsive to a PKC inhibitor by administering a polymer conjugate of the invention.
