Description

Biochem/physiol Actions

PAPTP is a PAP-1-derivatized Kv1.3-selective potassium channel blocker with a positively charged lipophilic propyl-triphenylphosphonium (TP) moiety that allows mitochondria-targeted PAPTP delivery. Mitochondria Kv1.3 inhibition induces oxygen species (ROS)-mediated cancer-selective killing both in cultures (by 28%/69%/95% post 24-hr 0/1/10 µM PAPTP treatment of primary B-CLL; 20%/24% normal B-cell death with 0/20 µM PAPTP) and in murine orthotopic models of melanoma and pancreatic ductal adenocarcinoma in vivo (5 µmol/kg q.o.d. via i.p.). PAPTP exhibits higher anti-cancer efficacy than PAP-1 both in vitro and in vivo, and and is less affected by ultidrug resistance (MDR).
