Biochem/physiol Actions

Macimorelin (AEZS-130; ARD-07; EP1572; UMV1843; Aib-DTrp-DgTrp-CHO) is an orally active peptido-mimetic growth hormone (GH) secretagogue (GHS) that targets human and animal GHS-receptor (IC50 in nM = 10.2/ghrelin, 12.3/hexaghrelin, 15.6/macimorelin against ghrelin binding to human GHS-R) with potent and selective GH-releasing activity in vivo (GH level = 158.8 μg/L 15 min post 300 μg/kg s.c. in neonatal rats; 11.3 μg/L without treatment).

EP1572 UMV1843 [Aib-DTrp-DgTrp-CHO]) is a new peptido-mimetic GH secretagogue (GHS) showing binding potency to the GHS-receptor in animal and human tissues similar to that of ghrelin and peptidyl GHS. EP1572 induces marked GH increase after s.c. administration in neonatal rats.

In models of status epilepticus ghrelin displays neuroprotective effects mediated by the growth hormone secretagogue-receptor 1a (GHS-R1a). This activity may be explained by anticonvulsant properties that, however, are controversial. We further investigated neuroprotection and the effects on seizures by comparing
