A graft copolymer having drug-containing side chains is described. The graft copolymer can be prepared, for example, by directly polymerizing a drug- containing monomer on multiple sites of a linear copolymer. When exposed to water, the graft copolymer can form uniform nanocarriers, e.g., nanomicelles, optionally encapsulating additional drugs, e.g., non-covalently in the interior of the nanocarriers, for coordinated drug delivery of a plurality of drugs. Also described herein is the use of the nanocarriers for delivery of therapeutic agents, particularly the dual delivery of chemotherapeutic agents to treat tumors.

A novel unsymmetrical structural class of orally bioavailable hepatitis C virus (HCV) nonstructural 5A protein (NS5A) inhibitors has been generated by improving both the solubility and membrane permeability of the lead compound found in our previous work. The representative compound 14, with a 5-hydroxymethylpyrazine group and a 3-t-butylpropargyl group on each side of the molecule, exhibited the best oral bioavailability in this study, inhibiting not only the HCV genotype 1a, 1b, 2a, and 3a replicons with EC50 values in the picomolar range, but also inhibited 1a Q30 mutants induced by launched symmetrical inhibitors with EC50 values in the low nanomolar range.
