Development of heat shock protein 90-targeted PDT for inflammatory breast cancer

Motivation of the study In photodynamic therapy (PDT), systemically administered photosensitizer is activated within the tumor using focused near-infrared light, typically a laser with a wavelength matching the absorption peak of the photosensitizer. Several photosensitizers have been clinically approved for treatment of different cancers; however, their accumulation is non-tumor exclusive which exposes healthy tissues to side effects like daylight-induced phototoxicity. A promising strategy to improve tumor selectivity is to couple… READ MORE

In vitro illumination using ML8500: osmium-based anticancer photosensitizer with highest hypoxic activity reported to date

  Study protocol to determine wavelength, fluence, and irradiance activities of Os-4T:   Key observations Illumination parameters significantly affected the phototoxicity of Os-4T. Green light (525 nm) was more effective than red light (630 nm) at lower fluences, while maximal potency was achieved at both wavelengths when using fluences higher than 100 J/cm2. Irradiance affected the potency with both red and green light that were more effective when lower irradiances… READ MORE
