monomethyl ether/hypoxia

The singlet oxygen quantum yield (Φ_Δ) was monitored in real time through time resolved spectroscopy measurement, using gadolinium labeled hematoporphyrin monomethyl ether (Gd-HMME) as photosensitizer. According to the kinetics equations of singlet oxygen generation and reaction,

The effects of photodynamic therapy (PDT) are limited by the hypoxic tumor microenvironment (TME). In this paper, a new type of biocompatible multifunctional photosensitizer delivery system was fabricated to relieve tumor hypoxia and improve the efficacy of PDT. The photosensitizer hematoporphyrin

Sonodynamic therapy (SDT) always causes tumor hypoxia aggravation which can induce malignant cell proliferation and drug resistance. To overcome these disadvantages, a cascaded drug delivery system (Lipo/HMME/ACF@MnO2 -AS1411) is constructed for synergistic enhanced sonodynamic therapy. First,

Tumor microenvironment, such as hypoxia and presence of immune cells, plays a critical role in cancer initiation, growth as well as progression, and seriously affects antitumor effect. Accordingly, we constructed a kind of multifunctional nanoparticles (NPs) with macrophage transformation and oxygen
