Abstract: The present invention accomplishes this by having multiple molecules of parent drugs attached to carrier moieties and by extending the period during which the parent drug is released and absorbed after administration to the patient and providing a longer duration of action per dose than the parent drug itself. Prodrug conjugates are suitable for sustained delivery of heteroaryl, lactam-amide-, imide-, sulfonamide-, carbamate-, urea-, benzamide-, acylaniline-, cyclic amide- and tertiary amine-containing parent drugs that are substituted at the amide nitrogen or oxygen atom with labile aldehyde-linked prodrug moieties. The carrier groups of the prodrugs can be hydrophobic to reduce the polarity and solubility of the parent drug under physiological conditions.
Abstract: The present invention provides fusion polypeptides comprising polypeptide ligands that are modified by circular permutation and fused to at least one polypeptide fusion partner wherein such fusion polypeptides have new, improved or enhanced biological functions or activities. Such improvements include, but are not limited to, increased binding affinity, increased activity, increased agonist activity (super agonist), antagonist activity, increased accessibility, increased flexibility of the active site, increased stability, broader and/or changed substrate specificity, and combinations thereof.
Abstract: The invention provides compositions and methods for modulating the immunostimulatory properties and/or anti-inflammatory properties of IL-10. The present invention provides scIL-10 polypeptides of Formula 1. The polypeptides of the invention are optionally linked to a fusion partner. The polypeptides of Formula 1 are referred to herein as “scIL-10” polypeptides and comprise an amino acid sequence arrangement from N-terminus to C-terminus in accordance with Formula 1: (first monomer subunit)-LINKER-(second monomer subunit)?? Formula 1 wherein the first monomer subunit, the second monomer subunit or both the first and second monomer subunits may be independently selected from: an unsubstituted IL-10 monomer subunit; or a substituted IL-10 monomer subunit comprising at least one amino acid substitution; and wherein LINKER is any amino acid linker of at least 1-100 amino acids in length.

Abstract: The invention provides fusion proteins having improved bioactivity comprising a first polypeptide fusion partner and a second polypeptide fusion partner wherein the first fusion partner is linked to the second fusion partner by a mucin-domain polypeptide linker and wherein the bioactivity of the fusion protein of the invention is improved as compared to fusion of the first polypeptide fusion partner and the second polypeptide fusion partner in the absence of the mucin-domain polypeptide linker. Mucin-domain polypeptide linkers comprise a mucin domain that is rich in potential glycosylation sites, and has a high content of serine and/or threonine and proline, which can represent greater than 40% of the amino acids within the mucin domain and further comprise at least about 60% of its mass due to the glycans.
