(October 31, 2018) Professor John Matson's recent paper titled, "Self-Assembled Nanostructures Regulate H2S Release from Constitutionally Isomeric Peptides" was published in the Journal of the American Chemical Society (JACS). The paper discussed short, self-assembling peptides designed by Matson group postdoc Yin Wang that slowly release hydrogen sulfide (H2S), a biological signaling gas. The released H2S limits death of heart cells exposed to the cancer drug doxorubicin. These materials may be useful in limiting the cardiotoxicity of this widely used chemotherapeutic, enhancing its effectiveness and reducing side effects. The Matson Lab focuses on macromolecular and supramolecular chemistry with applications in biology, medicine, and sustainability. View the full abstract here.
