The design and implementation of a generic lipopeptide scanning platform to enable the identification of ‘locally acting’ agonists for the apelin receptor

This Letter describes methodology to enable the identification of tool or therapeutic lipopeptides which modulate the function of membrane bound proteins. The choice of lipopeptides as a chemotype is the amalgamation of multiple medicinal chemistry considerations including duration of action, low systemic exposure and access to intracellular components. The ‘lipopeptide shuffle’ has been applied here to the APJ receptor and has rapidly resulted in the discovery of a 33 nM APJ agonist hit from an initial 369 member lipopeptide synthetic array.
