PRIMA-1MET?(5291-32-7) reactivates mutant p53, an important tumor suppressor gene, in cancer cells.1?It induces p53-dependent mitochondrial apoptosis?via?activation of caspase-2.2?PRIMA-1MET?showed significant antitumor activity in multiple myeloma?via?activation of p733?and had previously been shown to target p53 family members p63 and p734. Tumor cell death by PRIMA-1MET?has been also shown to be caused by glutathione depletion and induced ROS production in a p53 independent manner.5-7?PRIMA-1MET?probably induces tumor cell death by both reactivating mutant p53 and inhibiting cellular thiol-dependent redox systems.8 | [Uses]
2-(Hydroxymethyl)-2-(methoxymethyl)quinuclidin-3-one is a small molecule that has shown promising preclinical activity in various cancer types. 2-(Hydroxymethyl)-2-(methoxymethyl)quinuclidin-3-one shows antitumor activity in multiple myeloma by induction of p73 and Noxa. | [Biochem/physiol Actions]
PRIMA-1Met, also called APR-246, is converted to methylene quinuclidinone (MQ), a Michael acceptor. It interacts with p53 through the cysteine (Cys) residue. It blocks the thioredoxin reductase (TrxR1) enzyme. It is under clinical investigation and well-studied. PRIMA-1Met effect is tested on breast cancer specific gene expression. | [storage]
