Abstract

Hypoxia is a common symptom of many serious disorders, including cancer, ischemic strokes, and rheumatoid arthritis. It is a natural physiologic barrier seen in the microenvironment of solid tumors that has significantly restricted the therapeutic impact of photodynamic treatment (PDT). For oxygen-consumption photodynamic treatment (PDT), local hypoxia is an unfavorable obstacle in tumors. Angiogenesis, invasion, metastasis, and chemotherapy resistance are all affected by a shortage of oxygen. Furthermore, PDT has the possibility of aggravating hypoxia. Meanwhile, the troublesome aggregation-caused quenching effect affects the photosensitizer (PS) compounds utilized in PDT applications and dramatically reduces the efficiency with which deadly reactive oxygen species are produced. Over recent decades, hypoxia's potential as a therapeutic target has become more widely recognized. Because of their benefits in safety, target specificity, and tumor penetrability, peptides have been intensively explored to treat these disease conditions. Low drug/energy delivery effectiveness, drug resistance brought on by hypoxia, and tumor nonspecificity can all be mitigated using peptides. Three basic methods have recently been applied to use peptide-based nanomaterials to target hypoxia: (i) using hypoxic microenvironment-sensitive peptide linkers that could be split to liberate medicinal payloads; (ii) the merger foregoing, in which earmarks peptides to direct the system to hypoxic surroundings, allowing for selective cleavage; and (iii) target cellular environments using peptide ligands that are particular for a hypoxic environment, such as receptors of the cell surface that are upregulated. In this paper, we go over the advantages and limitations of using peptide-based hypoxia-targeting nanomaterials in a variety of therapeutic situations.
