Heme peptide materials for anti-inflammatory regenerative nanobiomedicine

Patent ·
OSTI ID:1637857
Heme released as a result of sustained injury leads to toxicity and triggers an inflammatory response and tissue damage. Heme oxygenase, an enzyme, recognizes, binds free heme and breaks it down as a part of the anti-inflammatory response. The present disclosure relates to a class of peptide amphiphiles that mimic the heme oxygenase function, and have shown that the designed peptide is able to bind and break down heme thus validating its potential as an anti-inflammatory agent that promotes tissue repair and useful in wound healing. The disclosed peptide sequence design provides control of amphiphile peptides' supramolecular structure and function. Applicants have shown that the incorporated heme molecule can transport CO, which suggests that the peptides can also transport NO, O2 and reactive oxygens, the molecules which are responsible for vasodilation, neurotransmission and cell death. Besides heme oxygenase function, it is believed that the designed peptides can recognize normal tissue adjacent to the damaged area and the peptide can self-assemble into fibers that promote healthy cell growth.
