Sample Use Guides

In Vitro Use Guide

The effect of the ATP-sensitive potassium channel opener emakalim (EMD 56431) on coronary vasodilation and cardioprotection in isolated rat hearts was investigated. EMD 56431 caused a significant increase in pre-ischemic coronary flow. Time to contracture and reperfusion function were significantly increased at 3, 10 and 30 microM concentrations. LDH release was significantly reduced at 10 and 30 microM concentrations. 1 microM glyburide completely abolished the protective effects found with 10 microM EMD 56431. When given during reperfusion only, 10 microM EMD 56431 showed no cardioprotection.
