Abstract: The invention provides methods of screening agents, conjugates or conjugate moieties, linked or linkable to agents, for capacity to be transported as substrates through the PEPT2 transporter. The invention also provides methods of treatment involving delivery of agents that either alone, or as a result of linkage to a conjugate moiety, are substrates of the PEPT2 transporter. The invention also provides conjugates comprising a pharmaceutical agent which is linked to a conjugate moiety that is a substrate for a PEPT2 transporter.

Abstract: Reagents and methods for detecting target proteins in a sample are provided. The reagents include a replicable genetic package, a protein displayed on an exterior surface of the package that is expressed from a heterologous nucleic acid borne by the package, and one or more antibodies complexed with the expressed protein and which have an open binding site for a target protein. Thus, a segment of the nucleic acid encodes for an epitope that is shared by the expressed polypeptide and the target protein. The reagents can be utilized individually or as part of a library or an array to bind target proteins within protein samples to form one or more complexes. By determining the sequence of the segment of the heterologous nucleic acid of a package within a complex, one can identify the target protein since the segment encodes for an epitope that is shared by the expressed and target proteins.
Abstract: Disclosed are compounds that exhibit high transport across the intestinal wall of an animal. The compounds may optionally be linked to drugs that are poorly absorbed or poorly transported across the intestinal wall after oral administration to provide for enhanced therapeutic, and optionally prolonged therapeutic, systemic blood concentrations of the drugs upon oral administration of the drug-compound conjugate. Also disclosed are pharmaceutical compositions containing and methods of using such compounds.

Abstract: OCTN2 is consistently expressed at high levels in brain microvessel endothelial cells. Disclosed herein are assays for determining whether a test material/molecule is a substrate for, and/or is actively transported by, the OCTN2 transporter, and therefore a candidate substrate for crossing the blood brain barrier. The assays are useful in screening for therapeutic, cytotoxic or imaging compounds used in the treatment or diagnosis of neurological diseases.
Abstract: BGT1 is consistently expressed at high levels in brain microvessel endothelial cells. Disclosed herein are assays for determining whether a test material/molecule is a substrate for, and/or is actively transported by, the BGT1 transporter, and therefore a candidate substrate for crossing the blood brain barrier. The assays are useful in screening for therapeutic, cytotoxic or imaging compounds used in the treatment or diagnosis of neurological diseases.
Abstract: GAT2 is consistently expressed at high levels in brain microvessel endothelial cells. Disclosed herein are assays for determining whether a test material/molecule is a substrate for, and/or is actively transported by, the GAT2 transporter, and therefore a candidate substrate for crossing the blood brain barrier. The assays are useful in screening for therapeutic, cytotoxic or imaging compounds used in the treatment or diagnosis of neurological diseases.
Abstract: OCT3 is consistently expressed at high levels in brain microvessel endothelial cells. Disclosed herein are assays for determining whether a test material/molecule is a substrate for, and/or is actively transported by, the OCT3 transporter, and therefore a candidate substrate for crossing the blood brain barrier. The assays are useful in screening for therapeutic, cytotoxic or imaging compounds used in the treatment or diagnosis of neurological diseases.
Abstract: Disclosed are methods for providing enhanced systemic blood concentrations of orally delivered drugs that are incompletely translocated across the intestinal wall of an animal. Also disclosed are methods for the sustained release of drugs, whether poorly or readily bioavailable via oral delivery to animals. Still further, disclosed are compounds and pharmaceutical compositions that are used in such methods.
Abstract: CAT1 is consistently expressed at high levels in brain microvessel endothelial cells. Disclosed herein are assays for determining whether a test material/molecule is a substrate for, and/or is actively transported by, the CAT1 transporter, and therefore a candidate substrate for crossing the blood brain barrier. The assays are useful in screening for therapeutic, cytotoxic or imaging compounds used in the treatment or diagnosis of neurological diseases.

Abstract: An electrode assembly and a method of forming an anhydrous reservoir layer of an electrode assembly in an electrotransport transdermal agent delivery device are provided. The reservoir layer is adapted to be placed in agent-transmitting relation with a body surface and an electrode in electrical contact with a power source and the reservoir layer. The method includes the steps of dissolving a beneficial agent in a solvent, applying the solvent and dissolved beneficial agent to a surface of a hydrophilic polymer filtration membrane, removing the solvent from the surface of the filtration membrane, and disposing the beneficial agent/filtration membrane within the electrode assembly.
