Endothelin-3, human, mouse, rabbit, rat , is a cyclic 21 amino acid peptide. It is an endogenous neuropeptide and potent vasoconstrictor.

(Glu2)-TRH, a metabolically stable analogue of Thyrotropin-releasing hormone (TRH), is a negative modulator for the cholinergic effect of TRH in the mouse brain. (Glu2)-TRH significantly attenuates TRH-induced hippocampal extracellular acetylcholine release. (Glu2)-TRH is not metabolized by thyroliberinase. (Glu2)-TRH manifests neuroprotective, antidepressant, anticonvulsant in the CNS.
