meso-5,10,15,20-Tetrakis-(N-methyl-4-pyridyl)porphine, Tetratosylate Purple solid. PROTECT FROM LIGHT. HYGROSCOPIC. PACKAGED UNDER INERT GAS. A potent inhibitor of human telomerase (IC50 = 6.5 µM). TMPyP4 binds strongly to DNA quadruplexes by stacking on the G-tetrads at the core of the quadruplex, resulting in telomerase inhibition. Fluoresces intensely in the presence of quadruplex DNA. Purity: ≥90% by TLC. CAS 36951-72-1. Ref.: Yamashita, T., et al. 2005. Bioorg. Med. Chem. 13, 2433. Izbicka, E., et al. 1999. Cancer Res. 59, 639. Anantha, N.V., et al. 1998. Biochemistry 37, 2709.
