详情描述

PK11007 is a mild thiol alkylator with anticancer activity. PK11007 stabilizes p53 via selective alkylation of two surface-exposed cysteines without compromising its DNA binding activity. PK11007 induces mutant p53 cancer cell death by increasing reactive oxygen species (ROS) levels.

How to use

In Vitro:

PK11007 (0-120 µM; 24 hours; four p53 wild-type cell lines and fours p53 mutant cell lines) treatment results in a large viability reduction in mutant p53 cell lines MKN1 (V143A), HUH-7 (Y220C), NUGC-3 (Y220C), and SW480 (R273H/P309S) at concentrations ranging from 15 to 30 µM. PK11007 induces mainly caspase-independent cell death[1]. PK11007 (0-60 µM; 3 hours or 6 hours; NUGC-4, NUGC-3, MKN1, HUH-6, and HUH-7 cancer cells) treatment up-regulates protein levels of the p53 target genes p21, MDM2, and PUMA in a mostly concentration-dependent manner in NUGC-3 (p53-Y220C), HUH-7 (p53-Y220C) and MKN1 (p53-V143A) cells, suggesting partial restoration of transcriptional activity to destabilized p53 mutants. PK11007 also increases p53 activity in HUH-6 and NUGC-4 cells, as indicated by the increase of MDM2, PUMA, and p21 protein levels. PK11007 (15-20 µM; 4.5 hours or 6 hours; MKN1, HUH-7, NUGC-3, HUH-6 cells) treatment increases transcription of p53 target genes in three mutant p53 cell lines after 6-h treatment. PUMA and p21 mRNA levels are up-regulated by a factor of 2 upon treatment of NUGC-3, MKN, and HUH-7 cells, as well as NOXA for the latter two. MDM2 levels are halved in MKN1 and NUGC-3 cells. PK11007 viability reduction is potentiated by glutathione depletion. To test whether PK11007 also increases ROS levels, NUGC-3, NUGC-4, HUH-6, HUH-7, and MKN1 cells with PK11007 are incubated for 2 h. There are elevated ROS levels in all cell lines after 2 h. In the mutant p53 cells MKN1, HUH-7, and NUGC-3, however, the ROS increase is higher at 60 µM PK11007 than in NUGC-4 and HUH-6 cells, suggesting that the higher PK11007 sensitivity of the mutant p53 cell lines is mediated by a stronger ROS induction. Basal and PK11007-induced ROS levels in MKN1 cells are at least twofold higher than in other cell lines. PK11007 inhibits cell proliferation, induces apoptosis and alters genes involved in cell death are all consistent with the ability of PK11007 to reactivate mutant p53.
