A new route to the synthesis of 14beta-alkylmorphinans, of interest as potential analgesics, has been developed. Several such morphinans have been produced by desulphurisation of the Diels-Alder cycloadducts of thebaine and thioaldehydes, or of related, rearranged codeinones. Several methods of desulphurisation were explored. For example the 8alpha-ethoxycarbonyl-7-thia cycloadduct (49a) gave the 6,7-didehydro-14beta-ethyl acetate derivative (114) on desulphurisation with Raney nickel, and also with tri-n-butyltin hydride; the (19S)-anilinoenone and thiobenzaldehyde codeinone derivatives (131) and (138), each gave 8beta,14beta-methano derivatives, i.e. (132) and (139), respectively, with Raney nickel; while the ethyl ester codeinone derivative (86) gave the 8beta,14beta-alkylcodone (128) on treatment with aluminium amalgam. Raney nickel was found to be the best method for desulphurisation. The Diels-Alder cycloadducts of thebaine and thioaldehydes were known to undergo molecular rearrangements ...

Hydrocodone is an opioid agonist of opioid receptors within the CNS. This morphinans structure substance blocks pain perception in the cerebral cortex of the brain. Hydrocodone decreases synaptic chemical transmission in the CNS, which in turn inhibits pain sensation into the higher centers of the brain. Agonist activities at the μ and kappa receptors can cause analgesia, miosis, and decreased body temperature. Agonist activity at the μ receptor can also cause the suppression of opiate withdrawal, while antagonist activity can result in precipitation of withdrawal. Hydrocodone acts at several locations within the CNS by involving several systems of neurotransmitters to produce analgesia, but the precise mechanism of action has not been fully understood. Opiate agonists dont change the threshold or responsiveness of afferent nerve endings to noxious stimuli nor the conduction of impulses along peripheral nerves. Instead, they alter the perception of pain at the spinal cord and higher ...

article{8565564, abstract = {Currently, there is mounting evidence that intermolecular receptor-receptor interactions may result in altered receptor recognition, pharmacology and signaling. Heterobivalent ligands have been proven useful as molecular probes for confirming and targeting heteromeric receptors. This report describes the design and synthesis of novel heterobivalent ligands for dopamine D-2-like receptors (D-2-likeR) and the -opioid receptor (OR) and their evaluation using ligand binding and functional assays. Interestingly, we identified a potent bivalent ligand that contains a short 18-atom linker and combines good potency with high efficacy both in -arrestin2 recruitment for OR and MAPK-P for D4R. Furthermore, this compound was characterized by a biphasic competition binding curve for the D4R-OR heterodimer, indicative of a bivalent binding mode. As this compound possibly bridges the D4R-OR heterodimer, it could be used as a pharmacological tool to further investigate the ...
H insertion products through cyclopropanation/ring-opening reactions. DFT calculations and cross-experiments indicate that, in this process, the ring opening of the cyclopropylmethyl ylide intermediate is rapid and reversible and the subsequent proton transfer is the rate-determining step. Further studies revealed that, based on the choice of the ylide and ester groups, as well as the base, the reaction could be steered towards either the ring-opening pathway or to the production of vinyl cyclopropanes. ...

Endogenous opioids acting at μ-opioid receptors (MOPR) mediate many biological functions. Pharmacological intervention at these receptors has greatly aided in the treatment of acute and chronic pain, in addition to other uses. However, the development of tolerance and dependence has made it difficult to adequately prescribe these therapeutics. A common single nucleotide polymorphism (SNP), A118G, in the MOPR gene can affect opioid function and, consequently, has been suggested to contribute to individual variability in pain management and drug addiction. Investigation into the role of A118G in human disease and treatment response has generated a large number of association studies across various disease states as well as physiological responses. However, characterizing the functional consequences of this SNP and establishing if it causes or contributes to disease phenotypes have been significant challenges. To clarify the functional mechanisms linking the OPRM1 A118G SNP to addiction and analgesia

Salutaridine reductase (NADPH) is a key enzyme involves in morphine biosynthesis. BLASTP search waer performed to found orthologous proteins across different plant species. Domain analysis of all orthologous proteins was performed using Pfam and it was observed that Adh_short domain was conserved across all proteins. 3D structure of Salutaridine reductase was not available in PDB database, therefore Homology model of Salutaridine reductase was constructed using HOMER. A template structure (PDB ID: 2PFG) was selected from protein databank (PDB) using BLASTP with BLOSUM62 sequence alignment scoring matrix. The protein model was validated using PROCHECK. The model structure was visualized and superimposed with template using Discovery Studio Visualizer (Accelrys) and Swiss PDBviewer.
Generalizations of NMDA-receptor antagonists to the discriminative stimulus effects of κ-opioid receptor agonists in rats were examined. Phencyclidine, MK-801, and ketamine, non-competitive NMDA-receptor antagonists, generalized to the discriminative stimulus effects of U-50,488H, but not those of TRK-820, whereas (±)-3-(2-carbaxypiperazine-4-yl) propyl-1-phosphonic acid (CPP), a competitive NMDA-receptor antagonist, and ifenprodil, an NR1/NR2B NMDA-receptor antagonist, did not, suggesting that non-competitive NMDA-receptor antagonists possess U-50,488H-like discriminative stimulus effects in rats. Since U-50,488H and phencyclidine both induce aversive effects, our findings indicate that the cue of the discriminative stimulus effects of U-50,488H and non-competitive NMDA-receptor antagonists may be associated with their aversive effects.,br,. ...

Well provide an overview of both methadone and levorphanol, including mechanism of action, dosing, adverse effect profile, and equianalgesic dosing. Well be employing interactive audience polling questions and patient cases for discussion.. Jeffrey Fudin, PharmD: Although methadone has a role in the treatment of opioid dependence, its unique mechanism of action, oral bioavailability, absence of active metabolites, and delayed withdrawal syndrome makes it a viable option for chronic pain management. With these benefits come multiple pitfalls, including variable pharmacokinetics, pharmacogenetic considerations, potential for multiple drug interactions, QTc prolongation, and an extended titration period. Thus, the risks of methadone ...

Absorption Following oral administration, MOVANTIK is absorbed with peak concentrations (Cmax) achieved at less than 2 hours. In a majority of subjects, a secondary plasma concentration peak of naloxegol was observed approximately 0.4 to 3 hours after the first peak. Across the range of doses evaluated, peak plasma concentration and area under the plasma concentration-time curve (AUC) increased in a dose-proportional or almost dose-proportional manner. Accumulation was minimal following multiple daily doses of naloxegol.. MOVANTIK as a crushed tablet mixed in water, given orally or administered through a nasogastric tube into the stomach, provides systemic naloxegol concentrations that are comparable to the whole tablet, with a median tmax of 0.75 and 1.5 hours (range 0.25 to 5 hours) for the crushed tablet given orally and the crushed tablet given via nasogastric (NG) tube, respectively [see Dosage and Administration (2.2)]..

I agree that AppleWorks has been shorted in prior columns, and I am sorry for that. For what it is worth, I have a constant flow of e-mails with similar complaints about the attention all the others are getting as well.. But I stand by my characterization. AppleWorks is not an outliner designed to outline a document like the ones I mentioned (and this month surveys FullWrite and WordPerfect). In those, you can use the outline functions as a skeleton to progressively fill out an entire document. When finished, you can then remove the outline functions (labels and-importantly-indents) and be left with an ordinary document.. AppleWorks outline function is designed to create internal outlines as part of a document, just like it and others support lists and tables. You cannot remove the indents in AW. I suppose you could write a long document in it as you could in any of the ones weve surveyed-and you would have named styles in a single pane. But in that case, unless I am mistaken, you would ...

TY - JOUR. T1 - High affinity [3H]dextrorphan binding in rat brain is localized to a noncompetitive antagonist site of the activated N-methyl-D-aspartate receptor-cation channel. AU - Franklin, P. H.. AU - Murray, T. F.. PY - 1992/2/21. Y1 - 1992/2/21. N2 - [3H]Dextrorphan recognition sites were characterized in rat brain membranes. The pharmacological profile and regional distribution of [3H]dextrorphan binding sites appear to distinguish these sites from those labeled either by [3H]dextromethorphan or by putative σ receptor radioligands. Data from thoroughly washed forebrain membranes suggest that [3H]dextrorphan predominantly labels a high affinity site defined by the activated state of the N-methyl-D-aspartate (NMDA) receptor-channel complex. Regulation of [3H]dextrorphan binding by specific modulators of NMDA receptor function suggests that [3H]dextrorphan binding is predominantly localized to a domain of the receptor-channel complex also recognized by the prototypical noncompetitive ...

Naloxegol (nal ox ee gol) is a pegylated, semisynthetic opiate receptor antagonist which is similar structurally to naltrexone, but is peripherally restricted and thus has few if any effects on the central nervous system. Naloxegol is a polyethylene glycol (PEG) derivative of alpha-naloxol, an opiate antagonist. The addition of the large PEG molecule to naloxol does not block its engagement with opioid receptors, but does prevent the drug from crossing the blood brain barrier. As a consequence, the opioid antagonist reverses the peripheral but not the central nervous system effects of opiates, such as pain relief and euphoria. In large, preregistration trials, naloxegol was found to increase spontaneous bowel movement frequency and reduce constipation related side effects of opiates used for analgesia in patients with chronic pain. ...

Metazocine is an opioid analgesic related to pentazocine. While metazocine has significant analgesic effects, mediated through a mixed agonist-antagonist action at the mu opioid receptor, its clinical use is limited by dysphoric and hallucinogenic effects which are most likely caused by activity at kappa opioid receptors (where it is a high-efficacy agonist) and/or sigma receptors. Metazocine is in Schedule II of the Controlled Substances Act 1970 of the United States as a Narcotic with ACSCN 9240 with a 19 gram aggregate manufacturing quota as of 2014. The free base conversion ratio for salts includes 0.81 for the hydrochloride and 0.74 for the hydrobromide. It is listed under the Single Convention for the Control of Narcotic Substances 1961 and is controlled in most countries in the same fashion as is morphine. The prototype benzomorphan, metazocine (6), can be obtained from a variation of the morphinan synthesis. Thus, reaction of the Grignard reagent from p-methoxybenzyl chloride (1) with ...
Opioid analgesics are the cornerstone drugs for the treatment of moderate-to-severe pain. Morphine and other analgesics like fentanyl, oxycodone and oxymorphone activate the µ opioid (MOP) receptor, the main type targeted for pharmacotherapy of pain. These drugs share the same pharmacological profiles including severe adverse effects such as respiratory depression, constipation, tolerance and physical dependence. Chemical approaches towards the identification of novel MOP analgesics with reduced side effects include structural modifications of morphinan-6-ones in key positions that are important for binding, selectivity, potency and efficacy at opioid receptors. A representative example is the development of the 14-O-methyl-substituted derivative of the clinically used MOP analgesic oxymorphone, namely 14-O-methyloxymorphone, and its 5-methyl-substituted analogue, 14-methoxymetopon. The focus of the present work is on structure-activity relationship (SAR) studies and in vitro and in vivo ...
