Abstract: Disclosed are peptides having non-canonical amino acids. These peptides are useful, for example, as protein binding agents. Libraries of such peptides can be used, for example to screen and select protein binding agents. The broader chemical space of the disclosed peptides can provide peptide with different, improved, more specific, and/or pharmaceutically compatible peptides and protein binding agents. In some forms, the peptides can have the following structure (I): including stereoisomers, pharmaceutically acceptable salts and prodrugs thereof, wherein R, R1, L1, L2, G, M, Y1 Y2 and SEQ are as defined herein. Methods associated with preparation and use of such peptides, as well as pharmaceutical compositions comprising such peptides, are also disclosed.

Abstract: The present application provides stable heterobiligands made up of peptide-based FOLR1 ligands and folate (the ligand of FOLR1) and methods of use of the heterobiligands as detection, imaging, diagnostic, and therapeutic agents. The application further provides methods of manufacturing FOLR1 heterobiligands, capture agents, and imaging agents.

Abstract: Disclosed are compounds, compositions, systems, and methods useful for treating disease (such as cancer and tumors), or binding, detecting, and affecting compounds, compositions, cells, tissues, and organs, where the compounds, compositions, systems, and methods include or involve toxic compounds and where the toxic effect of the compounds, compositions, systems, and methods is reduced by providing a cleavage site to facilitate separation of the toxic component from other components of the compound, composition, or system. Preferably the system is a composition delivery system comprising or using a composition as disclosed herein. In some forms, the cleavage of the composition delivers a therapeutic agent and avoids organ damage by the composition.

Abstract: Disclosed are peptides and methods useful for identifying and producing capture agents based on epitopes of a target. In particular, disclosed are peptides comprising an epitope, where the peptide is cross-linked, where the epitope corresponds to an epitope of a target, wherein the peptide does not include the entire target, and where the cross-link is a disulfide, preferably a disulfide that naturally occurs in the target or between added or substitute cysteines. Also disclosed are methods of preparing such peptides and methods of using such peptides. In particular, in methods of identifying a target binding compound.

Abstract: The present invention relates generally to methods of synthesis of vinaxanthone and xanthofulvin, novel analogs, and methods of use thereof.

Abstract: The present invention provides a method for converting an aromatic hydrocarbon to a phenol by providing an aromatic hydrocarbon comprising one or more aromatic C—H bonds and one or more activated C—H bonds in a solvent; adding a phthaloyl peroxide to the solvent; converting the phthaloyl peroxide to a di-radical; contacting the di-radical with the one or more aromatic C—H bonds; oxidizing selectively one of the one or more aromatic C—H bonds in preference to the one or more activated C—H bonds; adding a hydroxyl group to the one of the one or more aromatic C—H bonds to form one or more phenols; and purifying the one or more phenols.
