Dronedarone (SR 33589) is an amiodarone analogue which has an effective and promising treatment for Atrial fibrillation.

BQ-788 is a selective and potent ETB receptor antagonist with potential hypertensive activity.BQ-788 inhibits ET-1 binding to ETB receptors and inhibits exogenous ET-1-induced elevation of coronary artery perfusion pressure.

Regadenoson (CVT-3146) is an adenosine derivative and selective A2A adenosine receptor agonist with coronary vasodilating activity. Upon administration, regadenoson selectively binds to and activates the A2A adenosine receptor, which induces coronary vasodilation. This leads to an increase in coronary blood flow and enhances myocardial perfusion. Compared to adenosine, regadenoson has a longer half-life and shows higher selectivity towards the A2A adenosine receptor. This agent is a very weak agonist for the A1 adenosine receptor and has negligible affinity for the A2B and A3 adenosine receptors.

Fostedil is a calcium channel antagonist. KB-944 increased regional segment function in normal and ischemic regions and maintained distal coronary artery perfusion pressure, coronary flow and transmural regional myocardial blood flow during partial corona
