Mechanism of Action

Targets/IC₅₀/Ki	BMI-1
In vitro	PTC-028 is an orally bioavailable compound that decreases BMI-1 levels by posttranslational modification. This compound treatment selectively inhibits cancer cells in clonal growth and viability assays, whereas normal cells remain unaffected. Hyperphosphorylation-mediated depletion of cellular BMI-1 by this agent coupled with a concurrent temporal decrease in ATP and a compromised mitochondrial redox balance potentiates caspase-dependent apoptosis.
In vivo	In vivo, orally administered PTC-028, as a single agent, exhibits significant antitumor activity comparable with the standard therapy in an orthotopic mouse model of ovarian cancer. After administration of single oral doses to the CD-1 mice, total plasma AUC_0-24h are 10.9 and 26.1 mg/h/mL at doses of 10 and 20 mg/kg, showing dose proportional pharmacokinetics. The Cmax for this compound at 10 and 20 mg/kg is 0.79 and 1.49 mg/mL, respectively. The Cmax is reached at both dose levels 1-hour postdose after which plasma concentrations slowly reduce.
