“…Presumably, high myocardial levels can explain why comparatively low doses of both MDL 74,270 and MDL 73,404 are required for myocardial salvage in conditions of reperfusion injury. This relative myocardial selectivity of the two compounds represents an advantage over other antioxidants, such as superoxide dismutase or catalase, which have to be introduced into the ischemic myocardium by coronary venous retroinfusion in order to achieve adequate concentrations (18). Cardiac selectivity is apparently not limited to quaternary ammonium compounds (28.30) but is a feature common to many quaternary substituted compounds (37)(38)(39)43).…”

“…However, enzymatic elimination of reactive oxygen species by superoxide dismutase and catalase lacked in vivo efficacy in preclinical large animal models [9][10][11] although myocyte protection was achieved in vitro [12]. Alternatively, supplementation of physiological ROS scavengers such as GSH is an attractive option, since intracellular GSH levels decrease rapidly after ROS-exposure.…”

“…43 Favorable results in terms of preservation of regional myocardial function and reduction of infarct size were obtained after retrograde injection of recombinant tissue-type plasminogen activator, different calcium blockers, superoxide dismutase, catalase, and L-arginine. [43][44][45][46][47][48][49] However, despite these observations, the retrograde drug administration via the coronary venous system has not been introduced into clinical practice.In patients with chronic refractory ischemia, 2 treatment methods using a transvenous coronary approach were recently tested. The potential for percutaneous coronary artery bypass grafting in situ has been evaluated in animal models and different catheter-based techniques have been extensively tested.…”
