MM 07 is a biased apelin receptor agonist, with a KD of 300 nM in CHO-K1 cells and a KD of 172 nM in human heart.
MM 07 competes with nanomolar affinities for binding of [Glp65,Nle75,Tyr77] [125I]apelin-13 to human apelin receptors in CHO-K1 cells (KD, 300 nM) and human heart (KD, 172 nM, n=3)[1].
MM 07 causes a dose-dependent increase in cardiac output, and although there is a decrease in vascular resistance, this is without corresponding effects on BP. Administration of SNAP produces a profound fall in BP in both [Pyr1]apelin-13 and MM 07-treated groups; however, although cardiac output is significantly increased in response to SNAP in the MM 07 group, it is significantly reduced in the [Pyr1]apelin-13 group. Neither peptide causes a significant change in heart rate, respiratory rate, or temperature. Both [Pyr1]apelin 13 and MM 07 increases peak velocity above basal levels[1].
