 Use of Propafenone


Propafenone (SA-79), a sodium-channel blocker, acts an antiarrhythmic agent. Propafenone also has high affinity for the β receptor (IC50=32 nM)[1]. Propafenone blocks the transient outward current (Ito) and the sustained delayed rectifier K current (Isus) with IC50 values of 4.9 μm and 8.6 μm, respectively[2]. Propafenone suppresses esophageal cancer proliferation through inducing mitochondrial dysfunction and induce apoptosis[3].

Propafenone blocks the transient outward current (Ito) and the sustained delayed rectifier K current (Isus) with IC50 values of 4.9 μm and 8.6 μm, respectively[2]. Propafenone suppresses esophageal cancer proliferation through inducing mitochondrial dysfunction and induce apoptosis[3].

In Vitro Propafenone (5-25 μM) inhibits esophageal squamous cell carcinoma (ESCC) cell proliferation[3]. Propafenone causes mitochondrial dysfunction by a decreased mitochondrial membrane potential and reduced expression of Bcl-xL and Bcl-2[3]. Propafenone (10 and 20 μm) treatment significantly down regulates the expression levels of the anti-apoptotic proteins Bcl-xL and Bcl-2 in ESCC cells. Propafenone also reduces expression of p-ERK[3]. Cell Proliferation Assay[3] Cell Line: The human ESCC cell lines KYSE30, KYSE150 and KYSE270 Concentration: 5, 10, 15, 20, and 25 μm Incubation Time: 24, 48, and 72 hours Result: Gradually decreased cell proliferation over time and potently inhibited cell proliferation with increasing concentrations in KYSE30, KYSE150 and KYSE270 cells. Western Blot Analysis[3] Cell Line: The human ESCC cell lines KYSE30, KYSE150 and KYSE270 Concentration: 0, 10, and 20 μm Incubation Time: 72 hours Result: Significant downregulation of Bcl-xL and Bcl-2 expression levels was observed.
In Vivo Propafenone (20 mg/kg; intraperitoneal injection every other day) markedly suppresses the tumor burden with a decrease of 69.2%[3]. Propafenone also significantly inhibits tumor cell proliferation (mean index decreased from 56.3±6.7% in the DMSO-treated group to 20.7±5.1% in the 10 mg/kg propafenone-treated group and 11.3±4.0% in the 20 mg/kg propafenone-treated group)[3]. Animal Model: Female BALB/c nude mice bearing KYSE270-derived xenografts (6-8 weeks)[3] Dosage: 10 mg/kg or 20 mg/kg Administration: Intraperitoneally injected Result: Exerted a significantly inhibitory effect on the growth of tumor xenografts.
