Photodissociation of protonated Leucine-Enkephalin peptide in the VUV range
We present results of VUV action spectroscopy of gas-phase protonated Leucin-Enkephalin peptide. The experiment has been performed by coupling a linear quadrupole ion trap with a synchrotron radiation VUV ...

Gegen Qinlian decoction alleviates depression-like behavior by modulating the gut microenvironment in CUMS rats [PDF]
Background Gegen Qinlian Decoction (GQD) is a classical traditional Chinese medicine (TCM) formula primarily utilized for treating gut disorders. GQD showed therapeutic effects on several diseases in clinical and animal studies by targeting gut microbes.

Role of enkephalin derivative in promoting wound healing and scar remodeling via increased epidermal growth factor in a mouse model [PDF]
Background Enkephalin, an endogenous neuropeptide, binds to the delta (δ) opioid receptor and exerts an antinociceptive effect. Recent studies have suggested that neuropeptides might effectuate cutaneous wound healing.

Exposure to exogenous enkephalins disrupts reproductive development in the Eastern lubber grasshopper, Romalea microptera (Insecta: Orthoptera). [PDF]
Enkephalins play a major role in reproductive physiology in crustaceans; however their role in reproductive development in insects is largely unknown. We investigated the effect of exposure to exogenous leucine-enkephalin (Leu-Enk), methionine-enkephalin

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

‘Acetaldehyde‐enkephalins’: elucidation of the structure of the acetaldehyde adducts of methionine‐enkephalin and leucine‐enkephalin [PDF]
The two major endogenous opioid pentapeptides, methionine-enkephalin and leucine-enkephalin [ 1,2] rapidly react with acetaldehyde, under very mild conditions, to give an ‘acetaldehyde-enkephalin’ adduct, referred to as ‘acetaldehyde-enkephalin [Met’] and ‘acetaldehyde-enkephalin [Leu”], respectively 231.
