Chemical Structure
TMPO
Synonym(s): 3,3,5,5-Tetramethyl-1-pyrroline 1-oxide
- CAS No.: 10135-38-3
- Formula:C8H15NO
- Molecular Weight:141.21
IUPAC Name: 2,2,4,4-tetramethyl-3,4-dihydro-2H-pyrrole 1-oxide
InChIKey: GUQARRULARNYQZ-UHFFFAOYSA-N
SMILES: CC1(C)CC(C)(C)[N+](=C1)[O-]
Biological Activity: TMPO (3,3,5,5-Tetramethyl-1-pyrroline 1-oxide) is a spin trap targeting free radicals. TMPO is capable of scavenging superoxide, hydroxyl radicals and inhibits thymocyte apoptosis with EC50 values of 19.1 mM (MPS-induced) to 30.7 mM (Etoposide-induced) for inhibiting DNA fragmentation. TMPO reacts with intracellular free radicals to form stable nitroxide radical products, reducing oxidative stress (e.g., decreasing peroxide levels, maintaining glutathione content) and blocking oxidative events in the apoptotic pathway. TMPO is promising for research of apoptosis in immune cells like thymocytes[1][2].
