U-69593, a kappa opioid receptor agonist, decreases cocaine-induced behavioral sensitization in female rats
Behav Neurosci 2008 Feb;122(1):151-60.PMID:18298258DOI:10.1037/0735-7044.122.1.151.
This study was designed to investigate if the kappa opioid system regulates the locomotor response to cocaine in the female rat and to determine if the effect is dependent on estradiol treatment. Adult rats were ovariectomized (OVX) and half received an estradiol (OVX-EB) implant. After a week, rats were injected for 5 consecutive days with vehicle or with the kappa opioid receptor (KOPr) agonist U-69593 (0.16, 0.32, and 0.64 mg/kg) 15 min prior to cocaine injection (15 mg/kg). Following a 7-day drug-free period, rats were challenged with cocaine (Day 13). The locomotor response to cocaine was measured on Days 1, 5, and 13. U-69593 (0.32 mg/kg) decreased cocaine-induced locomotor activity in drug-naïve OVX rats and in those that received the OVX-EB implant. These results indicate that the acute effects of U-69593 are independent of estradiol treatment. Repeated exposure to U-69593 (0.32 mg/kg) prior to cocaine decreased the development of behavioral sensitization in OVX-EB-implanted rats. This decrease in cocaine-induced hyperlocomotion persisted after 1 week of cocaine withdrawal. These data indicate that the KOPr system participates in estradiol modulation of cocaine-induced behavioral sensitization in the female rat.
[3H]U-69593 a highly selective ligand for the opioid kappa receptor
Eur J Pharmacol 1985 Feb 26;109(2):281-4.PMID:2986999DOI:10.1016/0014-2999(85)90431-5.
The selective kappa agonist U-50488 was recently discovered and characterized. In this study, the receptor binding properties of [3H]U-69593, an analog of U-50488, were characterized. [3H]U-69593 binds with high affinity (3 nM) to membranes prepared from guinea pig, mouse and rat brain. The number of kappa binding sites comprise only 13%, 9% and 4% of the total opioid sites, respectively. The benzmorphans, dynorphin, and compounds structurally related to U-50488 have high affinity for this kappa site.
U-69593 prevents cocaine sensitization by normalizing basal accumbens dopamine
Neuroreport 1994 Sep 8;5(14):1797-800.PMID:7827335DOI:10.1097/00001756-199409080-00028.
Repeated intermittent administration of cocaine (20 mg kg-1, i.p.) for 3 days dramatically increased basal dopamine (DA) overflow in the nucleus accumbens (ACB) 48 h after the final daily injection. This cocaine pretreatment also produced a significant increase in stereotypy in response to a subsequent cocaine challenge. However, when the selective kappa-opioid receptor agonist U-69593 was administered in combination with cocaine for 3 days, these cocaine-induced biochemical and behavioral effects were abolished. It is suggested that the responsiveness of mesolimbic DA neurons to cocaine is intimately related to basal DA concentrations within the ACB and that U-69593, by normalizing cocaine-induced increases in basal DA overflow, may prevent the development of behavioral sensitization to cocaine.
Activation of micro, delta or kappa opioid receptors by DAMGO, DPDPE, U-50488 or U-69593 respectively causes antinociception in the formalin test in the naked mole-rat (Heterocephalus glaber)
Pharmacol Biochem Behav 2009 Feb;91(4):566-72.PMID:18929596DOI:10.1016/j.pbb.2008.09.011.
Data available on the role of the opioid systems of the naked mole-rat in nociception is scanty and unique compared to that of other rodents. In the current study, the effect of DAMGO, DPDPE and U-50488 and U-69593 on formalin-induced (20 microl, 10%) nociception were investigated. Nociceptive-like behaviors were quantified by scoring in blocks of 5 min the total amount of time (s) the animal spent scratching/biting the injected paw in the early (0-5 min) and in the late (25-60 min) phase of the test. In both the early and late phases, administration of 1 or 5 mg/kg of DAMGO or DPDPE caused a naloxone-attenuated decrease in the mean scratching/biting time. U-50488 and U-69593 at all the doses tested did not significantly change the mean scratching/biting time in the early phase. However, in the late phase U-50488 or U-69593 at the highest doses tested (1 or 5 mg/kg or 0.025 or 0.05 mg/kg, respectively) caused a statistically significant and naloxone-attenuated decrease in the mean scratching/biting time. The data showed that mu, delta or kappa-selective opioids causes antinociception in the formalin test in this rodent, adding novel information on the role of opioid systems of the animal on pain regulation.
[3H]U-69593 labels a subtype of kappa opiate receptor with characteristics different from that labeled by [3H]ethylketocyclazocine
Life Sci 1988;42(23):2403-12.PMID:2836684DOI:10.1016/0024-3205(88)90195-6.
[3H]U-69593 is an opiate agonist that has been reported to bind in vitro with high affinity and selectivity to the kappa receptor subtype. The studies reported here were designed to determine the optimal conditions for labeling kappa receptors with [3H]U-69593 and to further characterize the binding site. The effects of temperature and NaCl on [3H]U-69593 binding were of particular interest because previous studies reported that [3H]ethylketocyclazocine ([3H]EKC) and [3H]bremazocine binding to kappa receptors was optimal at 4 degrees C in the presence of NaCl. Those conditions were not found to be optimal for [3H]U-69593 binding. Although the pharmacological specificity and Bmax of [3H]U-69593 binding was similar at room temperature and at 4 degrees C, the binding affinity was approximately three times lower at 4 degrees C than at room temperature. In addition, NaCl had an effect on [3H]U-69593 binding that was opposite that on [3H]EKC binding at 4 degrees C (100 nM DAGO and 100 nM DADLE were included in all [3H]EKC assays to prevent binding to mu and delta receptors), i.e. NaCl decreased, rather than increased, [3H]U-69593 binding at 4 degrees C. These differences between [3H]U-69593 and [3H]EKC binding at 4 degrees C were accentuated by a vast difference in the density of the binding sites [Bmax approximately equal to 12 fmol/mg protein for [3H]U-69593 vs approximately equal to 375 fmol/mg protein for [3H]EKC at 4 degrees C in the presence of NaCl) and suggested that [3H]U-69593 might bind selectively to a kappa receptor subtype. This concept was supported by competition experiments. In particular, the site labeled by [3H]EKC at 4 degrees C was found to be relatively insensitive (compared to [3H]U-69593 and [3H]EKC binding at room temperature) to the kappa agonist U-50488H, a close analog to U-69593. Based on these findings, we propose that [3H]U-69593 (and U-50488H) labels a kappa receptor subtype which differs from that labeled by [3H]EKC at 4 degrees C.
