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.

Current drugs for epilepsy affect seizures, but no antiepileptogenic or disease-modifying drugs are available that prevent or slow down epileptogenesis, which is characterized by neuronal cell loss, inflammation and aberrant network formation. Ghrelin and ghrelin receptor (ghrelin-R) agonists were previously

Ghrelin and agonists of its receptor GHS-R1a are potential substances for the treatment of cachexia. In the present study, we investigated the acute and long term effects of the GHS R1a agonist JMV 1843 (H Aib-DTrp-D-gTrp-CHO) on food intake, body

Recent research suggests a role for ghrelin in the modulation of inflammatory disorders. However, the type of ghrelin receptor (GHS-R) involved in both the anti-inflammatory and anti-hyperalgesic actions of ghrelin remains to be characterized. In this study, we examined whether
