Abstract: The APJ receptor and its endogenous peptidic ligand apelin have been implicated as important modulators of cardiovascular function, and APJ receptor agonists may be beneficial in the treatment of heart failure. In this article, we describe the discovery of a series of biphenyl acid derivatives as potent APJ receptor agonists. Following the identification of initial high-throughput screen lead 2, successive optimization led to the discovery of lead compound 15a. Compound 15a demonstrated comparable in vitro potency to apelin-13, the endogenous peptidic ligand for the APJ receptor. In vivo, compound 15a demonstrated a dose-dependent improvement in the cardiac output in male Sprague Dawley rats with no significant changes in either mean arterial blood pressure or heart rate, consistent with the hemodynamic profile of apelin-13 in an acute pressure volume loop model.
