J Kamei et al.
European journal of pharmacology, 187(2), 281-286 (1990-10-09)
The effects of highly selective agonists of kappa-opioid receptors, namely U-50,488H and U-62,066E, on the capsaicin-induced cough reflex in rats were studied. Intracisternal (i.cist.) injection of U-50,488H and of U-62,066E significantly decreased the number of coughs in a dose-dependent manner.

Although studies suggest that 2-(3,4-dichlorophenyl-N-methyl-N-[(1S)-1-(3-isothiocyanatophenyl)-2-(1-pyrrolidinyl) ethyl] acetamide (DIPPA) has transient kappa-opioid-mediated agonist effects followed by long-lasting kappa-antagonist effects, its behavioral and pharmacological actions have not been systematically examined and there is evidence suggesting that some of its effects are species
David A White et al.
Brain research bulletin, 76(6), 597-604 (2008-07-05)
The primary objective of this study was to determine whether pretreatment with kappa- and delta-opioid agonists potentiates naltrexone-induced suppression of water consumption following 24h of deprivation. This study also examined the temporal effects of agonist-induced antinociception using the tail-flick and
S G Holtzman
Pharmacology, biochemistry, and behavior, 66(3), 517-522 (2000-07-19)
The results of a previous study in rats indicated that spiradoline has pharmacologically selective discriminative effects that are mediated by kappa-opioid receptors. However, the training dose, 3.0 mg/kg, increased response latencies, suggesting that it was relatively high. The current study
Glenn R Valdez et al.
The Journal of pharmacology and experimental therapeutics, 323(2), 525-533 (2007-08-19)
Kappa opioid agonists were at one time proposed as candidate pharmacotherapies for cocaine addiction, mainly because of their ability to decrease dopamine neurotransmission and attenuate the behavioral effects of cocaine in laboratory animals. Recent studies, however, suggest that kappa agonists
