Amiodarone 是治療心律不整的藥物, 心律不整是由於心臟不正常的神經傳導所引起。此藥的主要的作用再於控制心臟肌肉內電流的傳導。使心臟跳動的速率或節奏達到適當的程度。當心律不整嚴重時此藥通常用於治療較嚴重的心跳不規則或心室心率失常或物保留用於其它心律不整藥物無效的病人。它主要作用在於鬆弛過度活化的心肌。本文主要發現Amiodarone具有其他未被報導的新功能: 能夠抑制癌細胞的轉移(metastasis) :藉由抑制EGFR signaling 進而影響snail 與E-cadherin 表現達到抑制癌細胞的轉移的能力。 能夠抑制癌細胞的增生(proliferation) : 藉由抑制EGFR signaling 進而抑制AKT 與ERK 的磷酸化, 藉此達到抑制癌細胞的增生。 Amiodarone is categorized as a type III antiarrhythmic drug. It is considered a broad-spectrum antiarrhythmic agent because it has multiple and complex effects on the electrical activity of the heart. As such, Amiodarone is effective in treating tachyarrhymias, including re-entry supraventricular tachycardias, ventricular tachycardia, atrial arrhythmias and ventricular fibrillation. Here, the present invention provides a method for inhibiting cancer metastasis in a subject in need thereof comprising administering to the subject a pharmaceutically effective amount of an Amiodarone or its salt. Based on the present invention, the inhibition of cancer metastasis is due to an inhibition of epithelial-mesenchymal transition by the Amiodarone which is through an inhibition of EGFR signaling pathway by the Amiodarone to inhibit an expression of Snail and promotes an expression of E-cadherin.
