Purification and characterization of enkephalin convertase, an enkephalin-synthesizing carboxypeptidase.

open access: yesJournal of Biological Chemistry, 1983
Enkephalin convertase, an enkephalin-synthesizing carboxypeptidase present in adrenal medulla chromaffin granules, has also been detected in brain and pituitary. To determine whether these three carboxypeptidase activities represent the same enzyme, we purified and characterized enkephalin convertase from adrenal medulla, whole brain, and whole ...

RELEASE OF VASOPRESSIN BY ENKEPHALIN [PDF]

open access: yesBritish Journal of Pharmacology, 1978
Leu‐enkephalin, its stable analogue [D‐Ala2‐D‐Leu5]‐enkephalin and the C‐fragment of lipotropin (β endorphin) injected intravenously in the rat produced anti‐diuretic responses which were inhibited reversibly by naloxone. It was shown for Leu‐enkephalin that injection into the cerebral ventricles was at least ten times more effective than intravenous ...

The Opioid System in Temporal Lobe Epilepsy: Functional Role and Therapeutic Potential

open access: yesFrontiers in Molecular Neuroscience, 2017
Temporal lobe epilepsy is considered to be one of the most common and severe forms of focal epilepsies. Patients often develop cognitive deficits and emotional blunting along the progression of the disease.

The Effect of Exogenously Applied Dicarboxylic Acids (Photon) on the Maize (Zea mays) Metabolite Profile

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Maize is an important crop worldwide with approximately 1200 million tons consumed and a market size worth $143 billion. Environmental stress influence production of crops and mitigating these ensures optimum production. Dicarboxylic acids are known as emulsifying agents that mitigate various stresses in plants.

UPLC–ESI–QToF–MS Profile of Hydroalcoholic Extract of Persea cordata (Meisn.) and its Antioedematogenic and Antinociceptive Effects in Mice

open access: yesChemistry &Biodiversity, EarlyView.
Hydroalcoholic crude extract of Persea cordata showed in its composition, the presence of lignans based on LCESIMS data. This crude extract displayed anti‐oedematogenic and antinociceptive activities in vivo. Abstract This study aimed to establish the chemical profile and evaluate the anti‐oedematogenic and analgesic activities of the hydroalcoholic ...

Anxiety- and depressive-like responses and c-fos activity in preproenkephalin klockout mice: Oversensitivity hypothesis of enkephalin deficit-induced posttraumatic stress disorder

open access: yesJournal of Biomedical Science, 2010
The present study used the preproenkephalin knockout (ppENK) mice to test whether the endogenous enkephalins deficit could facilitate the anxiety- and depressive-like symptoms of posttraumatic stress disorder (PTSD).

Selank effects on morphine-induced analgesia in vivo experiments

open access: yesФармакокинетика и Фармакодинамика, 2022
Background. The endogenous opioid system is involved in neuroadaptation produced by exogenous opioids. Synthesized on the basis of the regulatory peptide tuftsin, the anxiolytic selank inhibits the activity of enkephalin-degrading enzymes, increasing the

Easier, Safer, and Greener: Unlocking the Power of Solid Reagents in Organic Reactions by Mechanochemistry

open access: yesChemistryEurope, EarlyView.
This review highlights the powerful synergy between mechanochemistry and solid reagents to replace hazardous substances traditionally used in organic synthesis. Such an approach offers a safer and more sustainable pathway for conducting organic reactions, with potential benefits in both reactivity and selectivity. The use of solid bases, acids, and gas

Analgesia linked to Nav1.7 loss of function requires µ- and δ-opioid receptors [version 1; referees: 2 approved]

open access: yesWellcome Open Research, 2018
Background: Functional deletion of the Scn9a (sodium voltage-gated channel alpha subunit 9) gene encoding sodium channel Nav1.7 makes humans and mice pain-free. Opioid signalling contributes to this analgesic state.
