The present disclosure provides methods for site-selectively crosslinking payloads to antibodies and other proteins. This can be accomplished using traceless affinity labels designed to label target proteins with bio-orthogonally reactive entities (ORE) using the compositions and methods described herein.

The present invention provides to compositions and methods useful in the treatment of neurological disorders including, but not limited to, Angelman syndrome, depression, traumatic brain injury, stroke, and Alzheimer's disease. CN2097, a rationally designed cyclic peptidomimetic drug that has been demonstrated to have effectiveness in preclinical models for the treatment of neurological disorders, is rapidly cleared and has a short half-life. The present invention provides a stable analog of CN2097.

Peptides useful in determining the presence of autoantibodies in patients suffering from rheumatoid arthritis are disclosed.

Peptides useful in determining the presence of autoantibodies in patients suffering from rheumatoid arthritis are disclosed.

The invention relates to compounds that are analogs of a cyclic peptide, cyclo[EKTOVNOGN], AFPep, that has anti-estrotrophic activity. The analogs of the invention include peptides and peptidomimetics that inhibit estrogen receptor-dependent cell proliferation. The compounds of the invention are useful for treating cell proliferative disorders or physiological conditions characterized by undesirable or unwanted estrogen induced cell proliferation, including breast cancer.
