Obs: 1. Se till att vätskan är klar innan du tillsätter nästa lösningsmedel.
2. Se till att tillsätta lösningsmedlet/lösningsmedlen i ordning. Du måste se till att lösningen som erhålls i föregående tillsats är en klar lösning innan du fortsätter att tillsätta nästa lösningsmedel. Fysiska metoder som vortex, ultraljud eller varmt vattenbad kan användas för att underlätta upplösningen.

Verkningsmekanism (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.
