Supramolecular peptide-drug conjugates (sPDCs) are prepared by covalent attachment of a drug moiety to peptide motif programmed for one-dimensional self-assembly, with subsequent physical entanglement these fibrillar structures enabling formation nanofibrous hydrogels. This class prodrug materials presents an attractive platform mass-efficient and site-specific delivery therapeutic agents using discrete, single-component molecular design. However, continued challenge in sPDC development is elucidating relationships between supramolecular interactions their domains the resultant impacts on assembly outcomes material properties. Inclusion saturated alkyl segment alongside hydrophobic domain sPDCs could relieve some necessity ordered, prodrug-produg interactions. Accordingly, nine here iterate design variables amino acid sequence prodrug-alkyl block All molecules spontaneously formed hydrogels under physiological conditions, indicating less hindered thermodynamic path self-assembly relative previous prodrug-only designs. studies arrangement, formation, mechanical properties as well release profiles showed complex function resulting assemblies. Together, results indicate that intrinsically linked holistic coupled contributions from directing emergent materials.
