Wirkmechanismus (Mechanism of Action)

Targets/IC₅₀/Ki	Mutant p53
In vitro	Eprenetapopt (APR-246), also known as PRIMA-1MET, is the first clinical-stage compound that reactivates mutant p53 and induces apoptosis. It is a prodrug that is converted to the active compound methylene quinuclidinone (MQ), a Michael acceptor that binds to cysteine residues in mutant p53 and restores its wild-type conformation. This compound not only reactivates p53 but also decreases intracellular glutathione levels in a dose-dependent manner. It can trigger apoptosis in a p53-independent manner by inducing ROS and endoplasmic reticulum (ER) stress and by inhibiting thioredoxin reductase 1 (TrxR1). It was also reported that APR-246 induces cell death in myeloma cells independently of p53 status by impairing the GSH/ROS balance. PRIMA-1Met/APR-246 efficiently inhibited the growth of the SCLC cell lines expressing mutant p53 in vitro and induced apoptosis, associated with increased fraction of cells with fragmented DNA, caspase-3 activation, PARP cleavage, Bax and Noxa upregulation and Bcl-2 downregulation in the cells.
In vivo	In a Phase I/II clinical dose-finding study on hematological malignancies and prostate cancer, Eprenetapopt (APR-246) showed a good safety profile, and both clinical and p53-dependent biological responses were observed. It is well tolerated in animal studies, and single treatment with this compound inhibits tumor growth by 21% in mice bearing the aggressively growing A2780-CP20 tumor xenografts.
