Abstract
?-Blockers reduce mortality and improve symptoms in people with heart disease. However, current clinically available ?-blockers have poor selectivity for the cardiac ?1-adrenoceptor (AR) over the lung ?2-AR. Unwanted ?2-blockade risks causing life-threatening bronchospasm and a reduction in the efficacy of ?2-agonist emergency rescue therapy. Thus current life-prolonging ?-blockers are contraindicated in people with both heart disease and asthma. Here we describe NDD-713 and NDD-825, novel highly ?1-selective neutral antagonists with good pharmaceutical properties that can potentially overcome this limitation. Radioligand binding studies and functional assays using human receptors expressed in CHO cells demonstrate that NDD-713 and NDD-825 have nanomolar ?1-AR affinity, greater than 500-fold ?1-AR vs ?2-AR selectivity and no agonism. Studies in conscious rats demonstrated that they are orally bioavailable and cause pronounced ?1-mediated reduction of heart rate while showing no effect on ?2-mediated hindquarters vasodilatation. The compounds also have good disposition properties and show no adverse toxicological effects. They potentially offer a truly cardioselective ?-blocker therapy for the large number of people with heart and respiratory, or peripheral vascular comorbidities.
