Chemical Name: 2-(10-hydroxy-3,7,9,11-tetramethyl-2,4,7,11-tridecatetraenyl)-5,6-dimethoxy-3-methyl-4-pyridinol. Alternate Names: Piericidin A1, Shaoguanmycin B, SN 198E, AR-054
Mitochondrial complex I inhibitor
Molecular Weight:
415.57
Purity:
94% by HPLC NMR (Conforms)
Form:
Yellow solid
CAS Number:
[2738-64-9]
Formula:
C25H37NO4
Application Notes:
A potent inhibitor of the mitochondrial and bacterial type I NADH-ubiquinone oxidoreductase (complex I).1 Piericidin A is a ubiquinone analog which binds to the ubiquinone binding site of the enzyme.2 It is an extremely useful tool for exploring the role of complex I in mitochondrial function in both normal and pathophysiology.3-5 Prevents upregulation of GRP78 and induces cell death in glucose-deprived, etoposide-resistant HT-29 cells (IC50=7.7 nM).6
