Amino Acid Sequence

Tyr-Ala-Gly-Nme-Phe-Gly-ol

General description

[D-Ala2, N-Me-Phe4, Gly5-ol]-Enkephalin acetate salt or DAMGO is a full agonist of the μ-opioid receptor. μ-opioid receptor is encoded by the OPRM1 gene, which has a predominant expression in reward-processing areas of brain. It acts as a receptor for endogenous opioids such as β-endorphin, encephalin, as well as foreign opioids such as morphine, heroin, and methadone.

Application

[D-Ala2, N-Me-Phe4, Gly5-ol]-Enkephalin acetate salt or DAMGO has been used:
  • for use as a positive control in the assay of G-protein activation with μ-opioid receptor, to assay the inhibition of cAMP inhibition by DAMGO
  • for the determination of the suppression of contraction by opioid receptors
  • to determine whether the peripheral application of DAMGO suppresses the hypertonic saline (HS)-induced masseter nociception in slightly anaesthetized rats

Biochem/physiol Actions

Enkephalin analog that is a selective agonist at μ-opioid receptors.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Designer receptors exclusively activated by designer drugs (DREADDs) are an advanced experimental tool that could potentially provide a novel approach to pain management. In particular, expression of an inhibitory (Gi-coupled) DREADD in nociceptors might enable ligand-dependent analgesia. To test this
