Opioid and anti‐opioid peptides

Fundamental and Clinical Pharmacology, 1995
Summary— The numerous endogenous opioid peptides (β‐endorphin, enkephalins, dynorphins…) and the exogenous opioids (such as morphine) exert their effects through the activation of receptors belonging to four main types: μ, Δ, k and ε. Opioidergic neurones and opioid receptors are largely distributed centrally and peripherally. It is thus not surprising

Non-opioid actions of opioid peptides

Life Sciences, 2004
Beside the well known actions of opioid peptides on mu-, delta- and kappa-opioid receptors, increasing amount of pharmacological and biochemical evidence has recently been published about non-opioid actions of various opioid peptides. These effects are not abolished by naloxone treatments.

Biology of Opioid Peptides

Annual Review of Pharmacology and Toxicology, 1979
Opioid peptides are endogenous or synthetic peptides, with a spectrum of pharmacological activity similar to that of morphine and other narcotic agonist drugs. The designation opioid peptide can be made if (a) it produces morphine-like, naloxone reversible effects in several in vitro bioassay sys­ tems such as the guinea pig ileum (1), the cat ...

Opioid peptides in cancer

Cancer and Metastasis Reviews, 2004
Opioid and somatostatin systems are two main inhibitory systems in mammals implicated in a variety of processes from hormone secretion to the modulation of cell proliferation. Opioids and opioid receptors were found in a great diversity of primary human tumors and in various cancer cell lines.

Opioid Peptides and their Receptors

1982
The three agonists, methionine-enkephalin, leucine-enkephalin and beta-endorphin have different pharmacological patterns. It may be of particular importance that they vary in their relative affinities to the enkephalin and naltrexone binding sites in the brain; the former are probably related to delta-receptors prevalent in the mouse vas deferens and ...
