Mechanism of Action

Features	An allele-specific p53 mutant reactivator.
Targets/IC₅₀/Ki	p53 (R175) 8 nM
In vitro	NSC319726 is a p53(R175) mutant reactivator, exhibits growth inhibition in cells expressing mutant p53, with IC50 of 8 nM for p53(R175) mutant, shows no inhibition for p53 wild-type cells, shows 10- to 100-fold selectivity over the other hotspot p53 mutants. NSC319276 induces p53(R175)-mutant-dependent apoptosis. NSC319726 treatment induces a WT-like conformational change in the p53(R175) mutant protein that restores sequence-specific p53 transcription. The activity of NSC319726 depends on the zinc ion chelating properties of the compound as well as redox changes.
Kinase Assay	MTS
Kinase Assay	5,000 cells of TOV112D cells (5,000 cells/well, in 100 ml culture) are cultured in 96-well plate to reach the 50%–60% confluence on the second day when treated with serial dilutions of the compounds. The growth is measured by MTS reagent and Victor Plate reader instrument after incubation for 3 days.
In vivo	NSC319726 (5mg/kg, 7days) exhibits greater toxicity for p53(R172H/R172H) mice, with only 30% survival, as compared to 100% survival for p53^+/+ and p53^-/- mice. NSC319726 inhibits the growth of TOV112D-p53(R175H) xenografts, but not H460 (p53^+/+) and MDAMB468-p53(R273W) xenografts.
