The results suggest that myEnteric δ- and κ-opioid receptors mediate the antitransit effects of opioids in the porcine small intestine and may be functionally coupled in a subpopulation of myenteric neurons.

It seemed of interest, therefore, to examine the kinetics of these drugs and for this purpose the following parameters were chosen: the concentration causing 50% inhibition of the contraction of the longitudinal muscle (ID50), to characterize agonist activity; the equilibrium constant and the recovery rate constant, to characterize antagonist activity.

Isolation and structural organization of the human preproenkephalin gene
- Biology, ChemistryNature

The general organization of the preproenkephalin gene is strikingly similar to that of the gene encoding the common precursor of corticotropin and β-lipotropin (β-LPH)7–9 (alternatively designated preproopiomelanocortin), another multi-hormone precursor.
