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).

Cellular energy metabolism is fundamental for all biological functions. Cellular proliferation requires extensive metabolic reprogramming and has a high energy demand. The Kv1.3 voltage-gated potassium channel drives cellular proliferation. Kv1.3 channels localise to mitochondria. Using high-resolution respirometry, we show Kv1.3
