Disease relevance of Endomorphin 1

 

Psychiatry related information on Endomorphin 1

  • These results suggest that endomorphin-1 improves the disturbance of short-term memory resulting from cholinergic dysfunction through the mediation of mu1-opioid receptors [5].
  • In contrast, physostigmine (0.025 and 0.05 mg/kg, i.p.) significantly reversed the endomorphin-1 (10 microg)- and endomorphin-2 (10 microg)-induced disturbance of passive avoidance learning, whereas physostigmine (0.025 and 0.05 mg/kg, i.p.) alone did not influence such learning [6].
  • The distribution of EM1 suggests a potential endogenous role for this peptide in major processes modulated by opiates, including affective states and social behavior [7].

Chemical compound and disease context of Endomorphin 1

  • Infusions of selective MOR agonists, H-Tyr-d-Ala-Gly-N-Met-Phe-glycinol-enkephalin (DAMGO) or endomorphin-1, into the medial preoptic nucleus attenuated lordosis, and their effects were blocked with the MOR antagonist H-d-Phe-Cys-Tyr-d-Trp-Orn-Thr-Pen-Thr-NH(2) (CTOP) [10].
