Abstract
Despite the availability of numerous pain medications, the current array of Food and Drug Administration-approved options falls short in adequately addressing pain states for numerous patients and consequently worsens the opioid crisis. Thus, it is imperative for basic research to develop novel and nonaddictive pain medications. Toward addressing this clinical goal, nalfurafine (NLF) was chosen as a lead and its structure-activity relationship (SAR) systematically studied through design, syntheses, and in vivo characterization of 24 analogues. Two analogues, 21 and 23, showed longer durations of action than NLF in a warm-water tail immersion assay, produced in vivo effects primarily mediated by KOR and DOR, penetrated the blood-brain barrier, and did not function as reinforcers. Additionally, 21 produced fewer sedative effects than NLF. Taken together, these results aid the understanding of NLF SAR and provide insights for future endeavors in developing novel nonaddictive therapeutics to treat pain.

Abstract
Morphinan-based opioids, derived from natural alkaloids like morphine, codeine and thebaine, have long been pivotal in managing severe pain. However, their clinical utility is marred by significant side effects and high addiction potential. This review traces the evolution of the morphinan scaffold in light of advancements in biochemistry and molecular biology, which have expanded our understanding of opioid receptor pharmacology. We explore the development of semi-synthetic and synthetic morphinans, their receptor selectivity and the emergence of biased agonism as a strategy to dissociate analgesic properties from undesirable effects. By examining the molecular intricacies of opioid receptors and their signaling pathways, we highlight how receptor-type selectivity and signaling bias have informed the design of novel analgesics. This synthesis of historical and contemporary perspectives provides an overview of the morphinan landscape, underscoring the ongoing efforts to mitigate the problems facing opioids through smarter drug design. We also highlight that most morphinan derivatives show a preference for the G protein pathway, although detailed experimental comparisons are still necessary. This fact underscores the utility of the morphinan skeleton in future opioid drug discovery.

Abstract
Defluorination of the readily available 21,21,21-trifluorothevinone (7) with Mg + Me3SiCl allows the preparation of 21,21-difluorothevinone (10) and 21-fluorothevinone (11), which can be used as the starting compounds for syntheses of 21,21-difluoro- and 21-fluoro-substituted relatives of thevinols and orvinols. Taken together, thevinols and orvinols are well known to constitute a family of the highly potent 4,5α-epoxy-18,19-endo-(etheno/ethano)morphinan-type opioid receptor ligands. Alternatively, 10 and 18,19-dihydro-21,21-difluorothevinone (13) have been synthesized by the addition of Me3SiCHF2 to the carbonyl function of thevinal (12) and dihydrothevinal (18) followed by oxidation of the intermediate C(21)-difluorinated secondary alcohols. 21,21-Difluorothevinols were obtained both by the addition of RMgX or RLi to the 21,21-difluoroketones and by the addition of Me3SiCHF2 to the carbonyl function of the non-fluorinated 18,19-endo-(etheno/ethano)morphinan ketones. In general, these addition reactions have been shown to result in mixtures of the C(21)-epimeric alcohols. However, in some cases, the reactions proceeded with high stereoselectivity allowing the isolation of one of the epimeric alcohols by conventional crystallization. Preparations of the 21,21-difluorothevinols bearing an allyl, cyclopropylmethyl, or cyclobutylmethyl group at the N(17) nitrogen are also reported.

Abstract
Thevinols and their 3-O-demethylated relatives, orvinols, are derivatives of the Diels-Alder adduct of natural alkaloid thebaine with methyl vinyl ketone. Taken together, thevinols and orvinols constitute an important family of opioid receptor (OR) ligands playing an important role in both the OR mediated antinociception and OR antagonism. Herein, we disclose for the first time the OR activity of orvinols fluorinated within the pharmocophore associated with C(20) and its surrounding along with a dependence of the activity profile on the substituent at N(17). Starting from thevinone and 18,19-dihydrothevinone, a family of C(21)-fluorinated orvinols bearing methyl, cyclopropylmethyl (CPM), and allyl substituent at N(17) was synthesized. The fluorinated compounds were evaluated for OR activity. The orvinols bearing three fluorine atoms at C(21) were found to retain the properties of OR ligands and their activity profile depends on the substituent at N(17). Pilot in vivo experiments in a model of acute pain (tail-flick test in mice) revealed that 6-O-desmethyl-21,21,21-trifluoro-20-methylorvinol at doses 1.0-10.0 mg/kg (s.c.) exhibits analgesic activity at the level of morphine for a duration of 30-180 min. Its N(17)-CPM counterpart demonstrated the partial opioid agonist properties. The N(17)-allyl substituted derivative showed no analgesic activity. In vivo evaluation of an analgesic activity indicates that 21,21,21-trifluoro-20-methylorvinols represent a novel family of OR ligands related to buprenorphine, diprenorphine, etc. These compounds are promising for the structure-activity relationship studies among the thevinol/orvinol series as well as for a search for new OR ligands with potentially valuable pharmacological profiles.

Abstract
The modulation and selectivity mechanisms of seven mixed-action kappa opioid receptor (KOR)/mu opioid receptor (MOR) bitopic modulators were explored. Molecular modeling results indicated that the 'message' moiety of seven bitopic modulators shared the same binding mode with the orthosteric site of the KOR and MOR, whereas the 'address' moiety bound with different subdomains of the allosteric site of the KOR and MOR. The 'address' moiety of seven bitopic modulators bound to different subdomains of the allosteric site of the KOR and MOR may exhibit distinguishable allosteric modulations to the binding affinity and/or efficacy of the 'message' moiety. Moreover, the 3-hydroxy group on the phenolic moiety of the seven bitopic modulators induced selectivity to the KOR over the MOR.

Abstract
RATIONALE Agonists of the kappa opioid receptor (KOR) have been shown to block the rewarding effects of drugs of abuse, but with negative side effects. The antipruritic drug nalfurafine, approved in Japan in 2009, is a potent, selective KOR agonist that does not cause significant side effects in humans. Nalfurafine has not been extensively tested for its effect on drug reward and reinforcement in preclinical models. OBJECTIVES The goal of this study was to compare the effects of nalfurafine and a reference KOR agonist for a variety of KOR-mediated endpoints in male C57BL6 mice. Specifically, we aimed to evaluate the "therapeutic window"-doses of agonists lower than those eliciting negative side effects, while still effective for desired therapeutic effects. METHODS In this study, several low doses of nalfurafine and U50,488 were tested for serum prolactin release, rotarod-mediated sedation, and place-conditioning in male C57BL6 mice. These agonists were also tested for effects on intravenous cocaine self-administration, both on an FR1 schedule and on a progressive ratio schedule for 0.5 mg/kg/infusion cocaine. RESULTS Serum prolactin levels increased following doses of both nalfurafine (3 μg/kg and 10 μg/kg) and U50,488 (3 mg/kg). These doses did not cause sedation in the rotarod assay or aversion in a place-conditioning assay, but blocked conditioned place preference for cocaine. Immediate pretreatment of mice with 10 μg/kg nalfurafine and 3 mg/kg U50,488, however, potentiated cocaine self-administration. Further 10 μg/kg nalfurafine was also observed to potentiate cocaine-seeking behavior as demonstrated by increased progressive ratio break point. CONCLUSIONS Both nalfurafine and U50,488 showed a separation of negative side effects and the modulation of cocaine reward, suggesting this effect of KOR agonists at low doses may be characteristic of the KOR system in general. At higher doses, nalfurafine had similar effects to traditional KOR agonists like U50,488, indicating that its relative potency, rather than differences in KOR signaling, may be responsible for its unique effects in humans.

Abstract
It is well documented in the literature that opioid receptors modulate a large number of physiological functions (pain perception, breathing, mood, gastrointestinal motility, etc.). Natural opiates and 4,5α-epoxymorphinan derivatives obtained by their chemical modifications, which are frequently referred to as semi-synthetic opioids, are among the most important types of opioid ligands. On the other hand, fluorinated compounds have a remarkable record in medicinal chemistry providing developmental candidates for therapeutic applications. The reasons are very similar steric impacts of hydrogen and fluorine along with the influence of substituting fluorine for hydrogen in the molecules of exogenous compounds on their lipophilicity, metabolism, conformation and other properties. This review focuses on the functionalization of 4,5α-epoxymorphinans and their derivatives via substitutions with fluorine or fluorine-containing groups in the search for improved pharmacological profile opioid ligands and 18F-containing opioid receptor radioligands for PET. These functionalizations are typically associated with substituents either at the C(3)-O, C(6)-O, and N(17) positions of the 4,5α-epoxymorphinan core or at C(7) in the thebaine based Diels-Alder type adducts. The syntheses resulted in the preparation of both single fluorinated derivatives or short sets of fluorinated derivatives and the families of fluorine-containing opioids allowing, in principle, the structure-activity relationship studies.

Abstract
We have recently reported that the elaboration of the N-substituent in the δ opioid receptor (DOR) antagonist naltrindole (NTI) enabled the regulation of the DOR activities from full inverse agonists to weak partial agonists. The investigations of amide-type NTI derivatives revealed that N-phenylacetyl and N-dihydrocinnamoyl derivatives 3a and 3b were DOR full agonists. The same transformations were applied to a DOR agonist KNT-127 to provide the more potent DOR agonists 6a and 6b. Among the tested compounds, the most efficacious compound 6a showed dose-dependent antidepressant-like effects in the mouse forced swim test. The antidepressant-like effects by 6a seemed to be more potent than those of KNT-127, which is a more potent DOR agonist in in vitro assays. The amide-type compound like 6a may more fully penetrate into the central nervous system.

Abstract
The cyclopropylmethyl group in classical δ opioid receptor (DOR) antagonist NTI, BNTX, and NTB was replaced with various electron-withdrawing groups to develop DOR inverse agonists. N-Benzyl NTB derivative SYK-657 was a potent DOR full inverse agonist and its potency was over 10-fold potent than that of a reference compound ICI-174,864. Intraperitoneal administration of SYK-657 induced the short-term memory improving effect in mice without abnormal behaviors.

Abstract
We designed and synthesized novel triplet molecules with 1,3,5-trioxazatriquinane skeletons. One class comprises double-capped triplets with a morphinan skeleton; the other class comprises simple phenol derivatives with phenethylamine moieties. One compound with m-phenolic hydroxyl group, called SYK-146, is a highly selective, potent agonist for the κ receptor, with activity nearly equivalent to that of U-50488H. The o-phenolic isomer of SYK-146, called SYK-524, showed potent but non-selective agonistic activity for the opioid receptors. We also added several simple phenol derivatives to a library of compounds that target opioid receptors, and they showed high hit rates for the receptor. This library might also be expected to show high hit rates for other receptors.

Abstract
This paper is the thirty-sixth consecutive installment of the annual review of research concerning the endogenous opioid system. It summarizes papers published during 2013 that studied the behavioral effects of molecular, pharmacological and genetic manipulation of opioid peptides, opioid receptors, opioid agonists and opioid antagonists. The particular topics that continue to be covered include the molecular-biochemical effects and neurochemical localization studies of endogenous opioids and their receptors related to behavior, and the roles of these opioid peptides and receptors in pain and analgesia; stress and social status; tolerance and dependence; learning and memory; eating and drinking; alcohol and drugs of abuse; sexual activity and hormones, pregnancy, development and endocrinology; mental illness and mood; seizures and neurologic disorders; electrical-related activity and neurophysiology; general activity and locomotion; gastrointestinal, renal and hepatic functions; cardiovascular responses; respiration and thermoregulation; and immunological responses.

The most effective influence of 17-(3-ethoxypropyl) substituent on the binding affinity and the agonistic activity in KNT-127 derivatives, δ opioid receptor agonists.

Abstract
We investigated the structure-activity relationship of KNT-127 (opioid δ agonist) derivatives with various 17-substituents which are different in length and size. The 17-substituent in KNT-127 derivatives exerted a great influence on the affinity and agonistic activity for the δ receptor. While the compounds with electron-donating 17-substituents showed higher affinities for the δ receptor than those with electron-withdrawing groups, KNT-127 derivatives with 17-fluoroalkyl groups (the high electron-withdrawing groups) showed high selectivities for the δ receptor among evaluated compounds. In addition, the basicity of nitrogen as well as the structure of the 17-N substituent such as the length and configuration at an asymmetric carbon atom contributed to agonist properties for the δ receptor. Thus, the analog with a 17-(3-ethoxypropyl) group showed the best selectively and potent agonistic activity for the δ receptor among KNT-127 derivatives. These findings should be useful for designing novel δ selective agonists.

The effect of 17-N substituents on the activity of the opioid κ receptor in nalfurafine derivatives. Bioorg Med Chem Lett 2012.

Abstract
We have previously reported the essential structure of the opioid κ receptor agonist nalfurafine hydrochloride (TRK-820) for binding to the κ receptor. In the course of this study, we focused on the effect of the substituent at 17-N in nalfurafine on the binding affinity for the κ receptor. The exchange of the 17-N substituent in nalfurafine from cyclopropylmethyl to fluoro-substituted alkyl groups, which are strong electron withdrawing substituents, almost completely diminished the binding affinities for the μ and δ opioid receptors, but the binding affinity for the κ receptor was still maintained. As a result, nalfurafine derivatives with 17-fluoro-substituted alkyl groups showed higher selectivities for the κ receptor than did nalfurafine itself. With regard to the κ agonistic activities, the conversion of the 17-N substituent in nalfurafine from cyclopropylmethyl to fluoro-substituted alkyl groups led to the gradual decrease of the agonistic activities in the order corresponding to their binding affinities for the κ receptor. In contrast, the derivative with the bulky 17-isobutyl group showed lower affinity and agonistic activity for the κ receptor than the derivatives with the smaller functional groups. This research suggested that both the electronic property and the steric characteristics of the 17-N substituent would have a great influence on the binding property for the κ receptor.
