Description
Dynorphin A ethylamide (1-9), The opioid activities were examined in the bioassays (guinea pig ileum, mouse vas deferens and rabbit vas deferens). the extension of the C-terminal in the peptide chain of [MeArg7,D-Leu8]-Dyn(1-8)-NH2 analogues by Arg is ineffective for increasing the kappa-opioid activities, kappa-receptor selectivity and/or analgesic effects of the peptides.
Uses
Daeatal (Dynorphin A ethylamide (1-9)) is an ethylamine-modified dynorphin fragment that can be used in the study of analgesia, addiction, depression, etc. Dynorphin A is an endogenous opioid peptide involved in inhibitory neurotransmission in the central nervous system (CNS). Dynorphin A is a highy potent kappa opioid receptor (KOR) agonist, and is also an agonist for other opioid receptors, such as mu (MOR) and delta (DOR). Dynorphin A can induce neuronal death, and can be used in the research of neurological disease[1].
