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).

Glioblastoma (GBM) is one of the most aggressive cancers, counting for a high number of the newly diagnosed patients with central nervous system (CNS) cancers in the United States and Europe. Major features of GBM include aggressive and invasive growth

A developing family of chemotherapeutics-derived from 5-(4-phenoxybutoxy)psoralen (PAP-1)-target mitochondrial potassium channel mtKv1.3 to selectively induce oxidative stress and death of diseased cells. The key to their effectiveness is the presence of a positively charged triphenylphosphonium group which drives their accumulation

Wnt signaling affects fundamental development pathways and, if aberrantly activated, promotes the development of cancers. Wnt signaling is modulated by different factors, but whether the mitochondrial energetic state affects Wnt signaling is unknown. Here, we show that sublethal concentrations of

The potassium channel Kv1.3 is highly expressed in the mitochondria of various cancerous cells. Here we show that direct inhibition of Kv1.3 using two mitochondria-targeted inhibitors alters mitochondrial function and leads to reactive oxygen species (ROS)-mediated death of even chemoresistant
Roberta Peruzzo et al.
Frontiers in oncology, 7, 239-239 (2017-10-17)
Previous results link the mitochondrial potassium channel Kv1.3 (mitoKv1.3) to the regulation of apoptosis. By synthesizing new, mitochondria-targeted derivatives (PAPTP and PCARBTP) of PAP-1, a specific membrane-permeant Kv1.3 inhibitor, we have recently provided evidence that both drugs acting on mitoKv1.3
