The apelin ligand receptor system is an important target to develop treatment strategies for cardiovascular diseases. Although apelin exhibits strong inotropic effects, its pharmaceutical application is limited because no agonist with suitable properties is available. On the one hand, peptide ligands are too instable, and on the other hand, small-mol. agonists show only low potency. This study describes the development of apelin (APJ) receptor agonists with not only high activity but also metabolic stability. Several strategies including capping of termini, insertion of unnatural amino acids, cyclization, and lipidation were analyzed. Peptide activity was tested using a Ca2+-mobilization assay and the degradation of selected analogs was analyzed in rat plasma. The best results were obtained by N-terminal lipidation of a 13-mer apelin derivative This analog displayed a half-life of 29 h in rat plasma, compared with 0.025 h for the wild-type peptide. Furthermore, in vivo pharmacokinetics revealed a clearance of 0.049 L h-1 kg-1 and a half-life of 0.36 h. In summary, amino acid substitution and fatty acid modification resulted in a potent and 1000-fold more stable peptide that exhibits high pharmaceutical potential.
