TMPyP4 tosylate
Chemical Name: 5,10,15,20-Tetrakis(1-methylpyridinium-4-yl)porphyrin tetra(p-toluenesulfonate)
Purity: ≥95%
Biological Activity
TMPyP4 tosylate is a cationic porphyrin; inhibits human telomerase. Stacks with G tetrads to stabilize quadruplex DNA. Inhibits cell proliferation and induces cell death in three myeloma cell lines. Activity results in telomere shortening at concentrations between 1 and 5 μM.Technical Data
