Abstract: Provided herein are polynucleotide encoded chemical libraries comprising one or more bead members, wherein the beads comprise: a chemical moiety comprising a compound library member; a polynucleotide moiety comprising an oligonucleotide encoding the compound library member, and a barcode identifying the bead; and a linking moiety, linking the chemical moiety to the polynucleotide moiety. Also provided herein are methods of making and using the polynucleotide barcoded chemical libraries, as well as kits comprising the barcoded chemical library.

Abstract: The present disclosure is directed to a novel class of peptide-like oligomers called peptide tertiary amides (PTAs) and a combinatorial library of PTAs along with synthetic routes for the preparation of large combinatorial libraries of these compounds. The peptide tertiary amides provide an exceptional source of high affinity and selective protein ligands that are useful as tools for biological research and as drug leads, among others.

Abstract: Synthesis of compounds having varying degrees of conformational rigidity is obtained via a low cost, high yield and efficient synthetic reactions. The library of compounds is structurally diverse, having at least one or more chiral centers and providing large numbers of compounds having building block diversity and substantial scaffold diversity. The compounds further provide a novel method for obtaining candidate therapeutic agents for prevention, treatment or diagnosis of diseases.

Abstract: Chiral oligomeric pentenoate amides are bio-oligomer mimetics possessing a high degree of conformation rigidity. Conformational rigidity is desirable in the design of molecules with high affinities for biological receptors and enzymes. Libraries of such oligomeric mimetics, such as of chiral oligomeric pentenoate amides can be used to probe biological systems. The present invention provides a method for preparation of chiral oligomeric pentanoate amides comprising conversion of a chiral oxazolidinone (4) to a chiral monomer of formula (1) which can be oligomerized to a chiral compound of formula (12) and so forth.

Abstract: The present invention provides for the identification of individuals having neurodegenerative diseases (ND). Peptoids recognized by Parkinson's Disease- and Alzheimer's Disease-specific antibodies are identified, allowing one to diagnose or predict ND in subjects.

Abstract: The present invention provides for the identification of an antigen surrogate to the native antigens for the autoimmune disease pemphigus vulgaris. Ligands are discovered using large random peptoid or cyclic peptoid libraries that are screened against known antibodies to autoimmune diseases. The ligands may be useful as drugs in the treatment of such diseases and can also be used in combination with the comcomitant removal of T-cells associated with autoimmune disorders.

Abstract: A cell-based screen is reported can be used to identify specific receptor-binding compounds in a combinatorial library of peptoids (N-alkylglycine oligomers) displayed on beads. This strategy was applied to the isolation of Vascular Endothelial Growth Factor Receptor 2 (VEGFR2)-binding peptoids, which were optimized to create lead compounds with high affinity for VEGFR2. One of these peptoids was shown to be an antagonist of VEGF-VEGFR2 interaction and receptor function.

Abstract: Combinatorial libraries were generated providing a vast number of diverse peptoid ligands. From these libraries, ligands were identified which specifically bind molecules associated with autoimmune diseases, such as antibodies specific to aquaporin-4 (AQP4), binding of which to AQP4 causes the autoimmune disease, Neuoromyelitis Optica. Methods of generating peptoid libraries and for diagnosing Neuromyelitis Optica are also provided.

Abstract: Embodiments of the invention are directed to a one-bead-two-compound method for the creation of encoded cyclic peptoid libraries. This scheme is useful for the creation of cyclic peptoid microarrays since only the cyclic peptoid, not the linear encoding molecule, contains an attachment residue and thus can be spotted onto an activated substrate.

Abstract: The present invention relates to methods and compositions for detecting a substance using mixed or multiple element capture agents (MECA). The affinity of a MECA for a target is produced by the concomitant binding of at least two low to moderate affinity capture agents providing a high affinity interaction with a capture target.
