Research/Areas of Interest

Bioorganic, Biophysical, & Chemical Biology. Peptides and their mimetics can target protein surfaces in ways small molecules rarely do, making peptide libraries attractive for screening for nontraditional modes of action. The Kritzer research group takes advantage of peptide and peptidomimetic libraries to bypass many of the disadvantages of small molecule screening. They also explore how modifications such as substitution of peptide bonds with isosteres, amide N-methylation, and head-to-tail cyclization affect the activities, specificities, and bioavailabilities of functional peptides. By combining powerful techniques from organic synthesis, biophysical chemistry, molecular biology and genetics, they are developing new molecules and new strategies to attack cancer, inflammation, and autoimmune diseases.
