Bis-penicillamine enkephalins possess highly improved specificity toward delta opioid receptors.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1983
The conformationally restricted, cyclic, disulfide-containing, enkephalin analogs [2-D-penicillamine, 5-L-penicillamine]enkephalin [(D-Pen2,L-Pen5]enkephalin) and [2-D-penicillamine, 5-D-penicillamine]enkephalin [(D-Pen2,D-Pen5]enkephalin) were ...

Downregulation of the endogenous opioid peptides in the dorsal striatum of human alcoholics

open access: yesFrontiers in Cellular Neuroscience, 2015
The endogenous opioid peptides dynorphins and enkephalins may be involved in brain-area specific synaptic adaptations relevant for different stages of an addiction cycle.

Neuropharmacological targets for drug action in vestibular sensory pathways [PDF]

open access: yes, 2017
The use of pharmacological agents is often the preferred approach to the management of vestibular dysfunction. In the vestibular sensory pathways, the sensory neuroepithelia are thought to be influenced by a diverse number of neuroactive substances that ...

Racecadotril for acute diarrhoea in children: systematic review and meta-analyses [PDF]

open access: yes, 2015
OBJECTIVE Racecadotril is an antisecretory agent that can prevent fluid/electrolyte depletion from the bowel as a result of acute diarrhoea, without affecting intestinal motility. An up-to-date systematic review is indicated to summarise the evidence on

THE DISTRIBUTION OF METHIONINE‐ENKEPHALIN AND LEUCINE‐ENKEPHALIN IN THE BRAIN AND PERIPHERAL TISSUES [PDF]

open access: yesBritish Journal of Pharmacology, 1977
A method is described for the rapid extraction of opioid peptides from the brain and other tissues. The method is based on acid extraction of tissues followed by adsorption of the extract onto Amberlite XAD‐2 resin. Elution with methanol separates the enkephalins and α‐endorphin from β‐endorphin.Over 90% of the opioid peptide activity isolated from ...

Crosslinking of membrane CD13 in human neutrophils mediates phagocytosis and production of reactive oxygen species, neutrophil extracellular traps and proinflammatory cytokines

open access: yesFrontiers in Immunology, 2022
Aminopeptidase N, or CD13, is a cell membrane ectopeptidase highly expressed in myeloid cells. Through its enzymatic activity, CD13 regulates the activity of several bioactive peptides, such as endorphins and enkephalins, chemotactic peptides like MCP-1 ...

The metabolism of neuropeptides. The hydrolysis of peptides, including enkephalins, tachykinins and their analogues, by endopeptidase-24.11.

open access: yesBiochemical Journal, 1984
Endopeptidase-24.11 (EC 3.4.24.11), purified to homogeneity from pig kidney, was shown to hydrolyse a wide range of neuropeptides, including enkephalins, tachykinins, bradykinin, neurotensin, luliberin and cholecystokinin.

Three-dimensional structure of monoanionic methionine-enkephalin: X-ray structure of tert-butyloxycarbonyl-Tyr-Gly-Gly-(4-bromo)Phe-Met-OH [PDF]

open access: yes, 1984
The conformation of tert-butyloxycarbonyl-Tyr-Gly-Gly-(4-bromo)Phe-Met-OH, as a monoanionic derivative of Met-enkephalin, was elucidated by X-ray crystal analysis. The molecule took an extended conformation which was bended at the Phe residue.

From morphine to endogenous opioid peptides, e.g., endorphins: the endless quest for the perfect painkiller

open access: yesSubstantia, 2018
Opium was known since the Neolithic era and in 5th century wild Papaver use was reported to induce sleep and relieving pain. First active component isolated from Opium was morphine, the paradigm of a natural product discovered 150 years before isolation ...
