DAMGO
Overview[edit | edit source]
DAMGO is a synthetic peptide that acts as a selective agonist for the mu-opioid receptor. It is widely used in neuroscience research to study the effects of mu-opioid receptor activation. The chemical structure of DAMGO is D-Ala2, N-MePhe4, Gly-ol5 enkephalin, which is a modified form of the naturally occurring enkephalins.
Structure[edit | edit source]
DAMGO is a peptide with the sequence D-Ala2, N-MePhe4, Gly-ol5 enkephalin. The modifications in its structure, such as the D-alanine and N-methylphenylalanine, enhance its selectivity and affinity for the mu-opioid receptor compared to natural enkephalins.
Mechanism of Action[edit | edit source]
DAMGO binds to the mu-opioid receptor, which is a G-protein coupled receptor (GPCR) located in the central nervous system. Upon binding, DAMGO activates the receptor, leading to the inhibition of adenylate cyclase, reduction of cAMP levels, and subsequent decrease in neurotransmitter release. This results in analgesic effects and other physiological responses associated with opioid receptor activation.
Applications in Research[edit | edit source]
DAMGO is primarily used in pharmacological and neuroscience research to investigate the role of mu-opioid receptors in pain modulation, reward pathways, and addiction. It serves as a tool to understand the physiological and behavioral effects of opioid receptor activation without the complications of using endogenous opioids.
