TMPyP4 (tosylate)

TMPyP4 is a cationic porphyrin that intercalates into and stabilizes G-quadruplexes, which are formed by DNA and RNA sequences composed of blocks of guanine residues. In this way, TMPyP4 inhibits telomerase activity (IC50 = 50 µM), blocking the clonogenic growth and migration of cancer cells in culture and in vivo. TMPyP4 also inhibits acetylcholinesterase at doses of 0.1 to 1.0 mM.Formal Name: 4,4',4'',4'''-(21H,23H-porphine-5,10,15,20-tetrayl)tetrakis[1-methyl-pyridinium], 4-methylbenzenesulfonate (1:4).
