K201, also known as JTV519 or JTV-519, is a 1,4-benzothiazepine derivative that was developed for its protective action against Ca2+-induced myocardial damage [1]. It was subsequently shown to be protective in models of ischaemia-reperfusion injury [2,3] and heart failure (HF) [4], has been in phase II clinical trials as a protective agent against acute myocardial infarction since 2000, and is suggested to reduce reperfusion injury following percutaneous transluminal coronary angioplasty (see http://www.jti.co.jp/JTI_E/IR/FR/0111/0111-Supplementary.pdf). Although like diltiazem, to which
