Targeting G protein‐coupled receptors for heart failure treatment

Abstract

Heart failure remains a leading cause of morbidity and mortality worldwide. Current treatment for patients with heart failure include drugs targeting G protein‐coupled receptors such as β‐adrenoceptor antagonists (β‐blockers) and angiotensin II type 1 receptor antagonists (or angiotensin II receptor blockers). However, many patients progress to advanced heart failure with persistent symptoms, despite treatment with available therapeutics that have been shown to reduce mortality and mortality. GPCR targets currently being explored for the development of novel heart failure therapeutics include adenosine receptor, formyl peptide receptor, relaxin/insulin‐like family peptide receptor, vasopressin receptor, endothelin receptor and the glucagon‐like peptide 1 receptor. Many GPCR drug candidates are limited by insufficient efficacy and/or dose‐limiting unwanted effects. Understanding the current challenges hindering successful clinical translation and the potential to overcome existing limitations will facilitate the future development of novel heart failure therapeutics.
