Biased Metropolis Sampling for Rugged Free Energy Landscapes [PDF]
, 2003 Metropolis simulations of all-atom models of peptides (i.e. small proteins) are considered. Inspired by the funnel picture of Bryngelson and Wolyness, a transformation of the updating probabilities of the dihedral angles is defined, which uses ...

Actions of D-Ala2-D-Leu5-enkephalin and dynorphin A (1–17) on neocortical neurons in vitro [PDF]
, 1984 Intracellular recordings were made from neocortical neurons in vitro. Application of D-Ala2-D-Leu5-enkephalin (DADL) by different methods produced a decrease in EPSP amplitude and in the amplitude of L-glutamate-induced depolarizations without changes in

Maturation of Circulatory Responses to Methionine-Enkephalin [PDF]
Pediatric Research, 1983 The cardiovascular and respiratory effects of the naturally occurring endogenous opiate, methionine-enkephalin, were studied in 23 fetal sheep, five newborn lambs, 15 pregnant sheep, and four nonpregnant ewes. The opiate peptide produced dose-dependent decreases in heart rate and blood pressure in fetal and neonatal lambs but increased heart rate and ...

Backbone Protecting Groups for Enhanced Peptide and Protein Synthesis
Angewandte Chemie, Volume 137, Issue 33, August 11, 2025.This review provides a comprehensive account of the use of backbone N‐protecting groups in peptide synthesis. It includes detailed synthetic methods relating to their introduction and removal and their application to “difficult” peptides and proteins of biological significance in both academic and industry contexts.

Methionine-enkephalin and leucine-enkephalin in human sympathoadrenal system and pheochromocytoma. [PDF]
Journal of Clinical Investigation, 1982 To elucidate the physiological and pathophysiological significance of methionine- and leucine-enkephalin (Met-and Leu-enkephalin, respectively) in human sympathoadrenal system, the contents of these peptides in normal human sympathetic nervous system, adrenal medulla, and pheochromocytomas were determined by specific radioimmunoassays combined with ...

Killing effect of methionine enkephalin on melanoma in vivo and in vitro
Oncology Report, 2017 Melanoma is a common cutaneous malignancy, that is also found in specific mucosal sites, and is associated with a poor prognosis. The aim of the present study was to investigate the cytotoxicity of methionine enkephalin (MENK) for B16 melanoma cells in ...

Opioid precursor protein isoform is targeted to the cell nuclei in the human brain [PDF]
, 2017 Background: Neuropeptide precursors are traditionally viewed as proteins giving rise to small neuropeptide molecules. Prodynorphin (PDYN) is the precursor protein to dynorphins, endogenous ligands for the kappa-opioid receptor.
