New life-saving treatments for Addictions in clinical trial on Behavioral and Neuroendocrine Effects of a Selective Kappa Opioid Receptor Antagonist

Rationale Several lines of evidence support a role for the endogenous opioid system in mediating behaviors associated with drug dependence. Specifically, recent findings suggest that the kappa-opioid receptor (KOR) may play a role in aspects of nicotine dependence, which contribute to relapse and continued tobacco smoking. Objective The objective of this study is to determine the involvement of the KOR in the initial behavioral responses of nicotine, nicotine reward, and nicotine withdrawal using the highly selective KOR antagonist JDTic.

N2 - Molecular modifications of both the kappa opioid antagonist norbinaltorphimine (norBNI, 1) and the kappa receptor have provided evidence that the selectivity of this ligand is conferred through ionic interaction if its N17 protonated amine group (an address) with a nonconserved acidic residue (Glu297) on the kappa receptor. In the present study, we have examined the effect of structural modifications on the affinity of norBNI analogues for wild-type and mutant kappa and mu opioid receptors expressed in COS-7 cells. Compounds 2, 3, and 7, which have an antagonist pharmacophore and basic N17 group in common with norBNI, ...

Mu and kappa opioid receptors often show antagonism in the regulation of physiological responses and behavior, including aggressive behavior. We report here our studies of the effects of acute administration of the selective mu opioid receptor antagonist CTAP (1 and 2 mg/kg, s.c.) and the selective kappa opioid receptor antagonist nor-BNI (0.5 mg/kg, s.c.) on manifestations of aggressive behavior in male C57BL/6 J mice with short (three days) and long (20 days) experience of victory in intermale confrontations. Animals with short experience of aggression were insensitive to blockade of both mu and kappa receptors. In males with long experience of aggression, administration of CTAP led to dose-dependent increases in the latent period of attacks but had no effect on attack duration. Administration of nor-BNI had no effect on the behavior of males with prolonged experience of aggression in antagonistic confrontations. Possible changes in the sensitivity of opioid receptors in male C57BL/6 J mice ...

0144] Although not wishing to be bound by any theory, it is believed that peripherally selective kappa opioid receptor agonist administered to subjects stimulates release of the anterior pituitary hormone prolactin. The compound is typically administered in an amount sufficient to stimulate secretion of prolactin, or stabilize or prevent or inhibit reductions or decreases in prolactin, without causing a severe side effect, such as CNS side effects or diuresis. A useful dose range of a peripherally selective kappa opioid receptor agonist can be determined by one of skill in the art through routine testing. One skilled in the art recognizes that a dose depends, in part, upon physical characteristics of the patient to be treated, e.g., body weight, as well as the route of administration, e.g., intravenous injection or transdermal delivery, and the bioavailability and plasma clearance of the compound by that route of administration, as well as the kappa opioid receptor affinity of the compound. One ...

U-50,488 (trans-3,4-dichloro-N-methyl-N-[2-(1-pyrrolidinyl)cyclohexyl]-benzeneacetamide) displays analgesic actions in a variety (thermal, pressure and irritant) of assays in mice and rats. Naloxone and MR-2266 block this analgesic effect; thus it is mediated by opioid receptors. However, when compared to morphine analgesia, the naloxone and MR-2266 pA2 values for U-50,488 analgesia were much lower and higher, respectively. Likewise, although tolerance occurs to both morphine and U-50,488 analgesia, there was no cross-tolerance between these drugs, and U-50,488 does not cause morphine-type physical dependence. These observations suggest that different opioid receptors mediate the analgesic effects of morphine and U-50,488. The effects of U-50,488 appear to be mediated by the so-called kappa opioid receptor. In contrast to U-50,488, other reputed kappa opioid agonists displayed varying degrees of mu agonist (ketazocine and ethylketocyclazocine) and narcotic antagonist (bremazocine) activities. ...

The indole moiety in the delta-opioid antagonist, naltrindole (2, NTI), was employed as a scaffold to hold an address for interaction with the kappa-opioid receptor. The attachment of the address to the 5-position of the indole moiety was based on superposition of NTI upon the kappa antagonist, norbinaltorphimine (1, norBNI). A variety of cationic groups were employed as a kappa address in an effort to investigate its interaction with the anionic address subsite, Glu297, on the kappa receptor. Some of the groups that were employed for this purpose were amines, amidines, guanidines, and quaternary ammonium. Members of the series were found to have a varying degree of kappa antagonist potency and kappa selectivity when tested in smooth muscle preparations. The 5-guanidine derivative 12a (GNTI) was the most potent member of the series and had the highest kappa selectivity ratio. GNTI was 2 times more potent and 6-10-fold more selective than norBNI (1). In general, the order of potency in the ...

The duration of ischemia was 10 or 45 min and the duration of reperfusion was 10 min or 2 h. Administration of 1 mg/kg U-50,488 both before ischemia and 5 min before reperfusion produced a pronounced antiarrhythmic effect. U-50,488 injected 5 min before reperfusion 2-fold reduced the ratio of infarction to risk area. Administration of ICI 199,441 in a dose of 0.1 mg/kg 15 min before ischemia ...

The varied behavioral effects of kappa opioid receptors (KOR) are mediated through different signaling cascades. KOR activation of G protein-dependent signaling results in analgesia, whereas the dysphoric effects are mediated by a different pathway involving G protein-coupled receptor kinase (GRK) and arrestin. Therefore, a partial KOR agonist that does not efficiently activate arrestin-dependent signaling may produce analgesia without dysphoria. No selective KOR partial agonists are currently available, and preclinical assessment is complicated by sequence differences between rodent (r) and human (h) KOR. KOR antagonists are also of therapeutic interest for their potential anxiolytic and antidepressant effects, but many KOR antagonists have long durations of action resulting from selective activation of cJun kinase (JNK). In this thesis, I compared the signaling events initiated by agonist stimulation of hKOR and rKOR. Although a partial agonist at both hKOR and rKOR, pentazocine was more ...

The effect of dexamethasone on acute opiate withdrawal induced by mu, kappa and delta receptor agonists was investigated in vitro. After a 4-min in vitro exposure to morphine (less selective mu agonist), D-Ala2-N-methyl-Phe4-Gly5-ol)-enkephalin (DAGO; highly selective mu agonist) and trans(+/-)-3,4-dichloro-N-methyl-N-[2(1-pyrrolidynyl)cyclohexyl]- benzeneacetamide (U50-488H; highly selective kappa agonist) a strong contracture of guinea pig isolated ileum was observed after the addition of naloxone. This effect was also observed when rabbit isolated jejunum was pretreated with deltorphin (highly selective delta agonist). Dexamethasone treatment before or after the opioid agonists tested was capable of both preventing and reverting the naloxone-induced contracture after exposure to mu opiate agonists morphine and DAGO in a concentration- and time-dependent fashion. Also, the steroid reduced naloxone-induced contracture after the exposure to U50-488H only when injected before the kappa opiate ...

Methamphetamine (METH) is a potent and highly abused psychomotor stimulant that produces powerful rewarding effects. Most of the scientific literature examining the neural mechanisms of METH have focused on the effect of this drug on the neurotransmitter dopamine. However, recent findings suggest that endogenous opioids are also affected by psychomotor stimulants such as METH, and that activation of these neurotransmitters may contribute to the rewarding and aversive effects induced by this drug. The current study is aimed at investigating the potential role of kappa opioid receptor activation in the response to METH in laboratory rats. METH was administered in the presence or absence of norbinaltorphimine (nor-BNI), a kappa opioid receptor antagonist, and locomotor activity and ultrasonic vocalizations (USVs) were assessed. In a pilot study, nor-BNI (5.0 mg/kg) increased METH-induced (3.0 mg/kg) 50 kHz USVs and locomotor activity, which is consistent with our hypothesis. We are currently replicating

MOR signaling in the VTA plays an important role in reward processing and aspects of addiction (Bozarth and Wise, 1984; Wise, 1989; Laviolette et al., 2004), including opiate withdrawal (Bonci and Williams, 1997; Madhavan et al., 2010a). We now show inverse agonistic effects at the MOR in the VTA, likely suggesting a role for constitutive agonist-independent MOR activation in the regulation of GABAergic control of VTA dopamine neurons. Furthermore, such MOR constitutive activity is especially prominent during morphine withdrawal.. The MOR-dependent inverse agonism by KC-2-009 on mIPSC frequency in the VTA is most likely best explained by suppression of constitutive MOR activity. Indeed, the effect of KC-2-009 was reliably blocked by the selective MOR neutral antagonist CTOP. While KC-2-009 also has low affinity for the KOR (Sally et al., 2010), its inverse agonistic effect was not blocked by the selective KOR antagonist Nor-BNI. Moreover, the effect of KC-2-009 was not due to interference with ...

Molecular changes induced by excessive alcohol consumption may underlie formation of dysphoric state during acute and protracted alcohol withdrawal which leads to craving and relapse. A main molecular addiction hypothesis is that the upregulation of the dynorphin (DYN)/κ-opioid receptor (KOR) system in the nucleus accumbens (NAc) of alcohol-dependent individuals causes the imbalance in activity of D1- and D2 dopamine receptor (DR) expressing neural circuits that results in dysphoria. We here analyzed post-mortem NAc samples of human alcoholics to assess changes in prodynorphin (PDYN) and KOR (OPRK1) gene expression and co-expression (transcriptionally coordinated) patterns. To address alterations in D1- and D2-receptor circuits, we studied the regulatory interactions between these pathways and the DYN/KOR system. No significant differences in PDYN and OPRK1 gene expression levels between alcoholics and controls were evident. However, PDYN and OPRK1 showed transcriptionally coordinated pattern ...

G-protein coupled opioid receptor that functions as receptor for endogenous alpha-neoendorphins and dynorphins, but has low affinity for beta-endorphins. Also functions as receptor for various synthetic opioids and for the psychoactive diterpene salvinorin A. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors, such as adenylate cyclase. Signaling leads to the inhibition of adenylate cyclase activity. Inhibits neurotransmitter release by reducing calcium ion currents and increasing potassium ion conductance. Plays a role in the perception of pain. Plays a role in mediating reduced physical activity upon treatment with synthetic opioids. Plays a role in the regulation of salivation in response to synthetic opioids. May play a role in arousal and regulation of autonomic and neuroendocrine functions.

POCD is a common complication following cardiac surgery and may lead to an extended stay in an intensive care unit or hospital, increased perioperative complications and mortality and a decrease in the ability of the patient to lead an independent life (2). At 1 week following cardiac surgery, the incidence of POCD is as high as 50-70 and ~40% of patients still have cognitive dysfunction at five years following surgery (37,38). CPB surgery can reduce postoperative neurocognitive ability because of hypoperfusion or low mean arterial pressure, hemodynamic instability, cerebral thrombosis, systemic inflammatory responses, anemia, hyperglycemia and extracorporeal circulation trauma (39). In the present study, a CPB rat model was successfully established and treated with a KOR agonist and then the cognitive function, inflammatory response, oxidative stress injury and apoptosis were observed. The results demonstrated that a KOR agonist could improve cognitive function and reduce brain damage in CPB ...

Highlights: The opioid system is, thus, a new regulator of vascular development that simultaneously modifies 2 distinct vascular properties, EC differentiation and vascular pathfinding. We confirmed that KOR, but not MOR, was highly expressed in various ECs such as HUVECs (data not shown), suggesting that KOR agonists could directly act on tumor ECs to suppress VEGF receptor expression, similar to the effects observed in embryonic ECs. If so, a combination therapy including an MOR agonist, morphine, and a KOR agonist (such as TRK820, a clinically approved drug in Japan for uremic pruritus) may prove useful for cancer therapy through the suppression of tumor angiogenesis by dual inhibition of VEGF ligands and receptors, extending the therapeutic benefits beyond pain relief ...

mRNAs localize to specific regions within neurons, where they can be translated to quickly generate large amounts of a protein in the place where it is needed. Due to the large size of neurons, this is much more efficient than translating all mRNAs in a single place and then shipping out each protein to its site of action. But the movement and translation of these mRNAs must be tightly regulated, potentially by extracellular signals such as growth factors.. Tsai et al. discovered that EGF boosts expression of the κ-opioid receptor (KOR) by stimulating both the nuclear export and translation of KOR mRNA. The key to this dual control was an RNA-binding protein called Grb7. EGF prods a phosphatase called SHP-2 to dephosphorylate Grb7 in the nucleus, prompting it to bind KOR mRNA and recruit a protein complex involved in nuclear export. But EGF also stimulated focal adhesion kinase to rephosphorylate Grb7 in the cytoplasm, causing it to release the mRNA for translation into KOR protein.. Senior ...

The antinociceptive effect of intrathecally (i.t.) administered protease inhibitors was tested against capsaicin (800 ng) injected into the dorsal surface of a hindpaw. Both p-hydroxymercuribenzoate (2-8 nmol), a cysteine protease inhibitor, and phosphoramidon (1-4 nmol), an endopeptidase 24.11 inhibitor in the presence of bestatin (0.25 nmol) an aminopeptidase inhibitor, administered i.t. 60 min prior to the injection of capsaicin produced a dose-dependent reduction of the capsaicin-induced paw licking and biting response. p-Hydroxymercuribenzoate (4 nmol)-induced antinociception was significantly antagonized by nor-binaltorphimine, a selective kappa-opioid receptor antagonist, but not by naltrindole, a selective delta-opioid receptor antagonist. On the other hand, phosphoramidon (4 nmol) /bestatin-induced antinociception was significantly antagonized by naltrindole, but not by nor-binaltorphimine. The results indicate that the antinociceptive effect of p-hydroxymercuribenzoate may be due to ...

Dynorphin is one of the endogenous opioids that modulates the excitability of nociceptive (pain-sensing) neurons. We have shown recently that dynorphin blocks NMDA-activated currents directly without the participation of kappa-opioid receptors. In order to understand the mechanism underlying this novel action of dynorphin, we examined, in detail, the interactions between dynorphin and NMDA receptors in isolated trigeminal neurons. Dynorphin reversibly blocks NMDA-activated current (INMDA). The onset and recovery of the block were determined with concentration jump experiments. The association rate (k+) of dynorphin(1-17) is 4.9 x 10(6) sec-1 M-1 and the dissociation rate (k-) is 7.5 sec-1. The apparent dissociation constant (KD) of dynorphin, calculated from these rate constants, is 1.6 microM. Dynorphin does not change the EC50 of NMDA, nor the potentiating action of glycine. The binding site for dynorphin is distinct from that of Zn2+ or H+. Upon treatment with the disulfide reducing agent ...

Agonists targeting MOR are effective analgesics, but their clinical use is hindered by side effects, including tolerance and addiction. KOR agonists also produce analgesia, but clinical use of these compounds has remained minimal due to aversive properties in humans. The µ-opioid receptor (MOR) agonists, morphine and fentanyl, both activate c-Jun N-terminal kinase (JNK), which is required for spinally-mediated morphine acute analgesic tolerance, whereas acute analgesic tolerance to fentanyl is blocked by G protein-coupled receptor kinase 3 (GRK3) gene deletion. Similarly, the κ-opioid receptor (KOR) collateral antagonist, norBNI, stimulates phosphorylation of JNK, and JNK1 is specifically required for norBNIs long duration of antagonism. The durations of action of a broad range of KOR antagonists, including norBNI, positively correlate with the ability of the antagonist to activate JNK1 (Melief et al., 2011), whereas there is no correlation between duration of antagonist action and drug ...
