ML7710 for photoimmunotherapy against regulatory T cells in tumors

      Experiments Tumor-bearing mice were randomized into 4 groups: 1) no treatment (control), 2) anti-CD25 full IgG antibody (no light activation), 3) anti-CD25 F(ab’)2 fragment, and 4) anti-CD25 full IgG antibody. NIR light using ML7710 (689 nm, 150 mW/cm2, 50 J/cm2) was administered to group 3 and 4 mice on day 1 (PIT). Tumor volumes were monitored for 21 days and survival of mice for up to 80… READ MORE

ML7710 for fluorescence imaging: Detection of colorectal polyps in humans using c-Met targeted fluorescent peptide

Motivation for the study Polyps are small growths on the inner lining of the colon or rectum, affecting around 1 in 4 people over the age of 50. Certain types of polyps may eventually become cancerous, and colon cancer prevention relies on colonoscopy using white light to detect and remove the polyps. However, small and flat polyps are difficult to detect and frequently missed with this technique. More precise methods… 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
