Regiospecific Introduction of Halogens on the 2-Aminobiphenyl Subunit Leading to Highly Potent and Selective M3 Muscarinic Acetylcholine Receptor Antagonists and Weak Inverse Agonists

Muscarinic M-3 receptor antagonists and inverse agonists displaying high affinity and subtype selectivity over the antitarget M-2 are valuable pharmacological tools and may enable improved treatment of chronic obstructive pulmonary disease (COPD), asthma, or urinary incontinence. On the basis of known M-3 antagonists comprising a piperidine or quinuclidine unit attached to a biphenyl carbamate, S-fluoro substitution was responsible for M-3 subtype selectivity over M-2, while 3′-chloro substitution substantially increased affinity through a sigma-hole interaction. Resultantly, two piperidinyl- and two quinuclidinium-substituted biphenyl carbamates OFH243 (13n), OFH244 (13m), OFH3911 (14n), and OFH3912 (14m) were discovered, which display two-digit picomolar affinities with K-i values from 0.069 to 0.084 nM, as well as high selectivity over the M-2 subtype (46- to 68-fold). While weak inverse agonistic properties were determined for the biphenyl carbamates 13m and 13n, neutral antagonism was observed for 14m and 14n and tiotropium under identical assay conditions.

Antinociceptive effects of novel histamine H-3 and H-4 receptor antagonists and their influence on morphine analgesia of neuropathic pain in the mouse

Background and Purpose The histaminergic system is a promising target for the development of new analgesics, as histamine H-3 and H-4 receptors are expressed in regions concerned with nociceptive transmission. Here we have determined the analgesic effects of new H-3 and H-4 receptor antagonists in naive and neuropathic mice. Experimental Approach We used chronic constriction injury (CCI) to the sciatic nerve in mice to model neuropathy. Effects of a new H-3 receptor antagonist, E-162(1-(5-(naphthalen-1-yloxy)pentyl)piperidine) and H-4 receptor antagonist, TR-7(4-(4-chlorophenyl)-6-(4-methylpiperazin-1-yl)-1,3,5-triazin-2-amine) were assessed on mechanical (von Frey) and thermal (cold plate, tail flick) stimuli in mice with and without CCI (7days after injury). Effects of these antagonists on morphine analgesia were also evaluated, along with the possible participation of H-1 receptors in their effects. We analysed the compounds in binding and functional cAMP assays at the H-3 and H-4 receptors and determined metabolic stability. Key Results E-162 and TR-7 attenuated nociceptive responses and profound morphine analgesia in males with CCI. These antagonists showed analgesia in naive mice (tail flick test) and produced prolonged analgesia in neuropathic females. E-162-induced analgesia was reversed by pyrilamine, an H-1 receptor antagonist. E-162 bound potently to H-3 receptors (K-i=55nM) and inhibited cAMP accumulation (IC50=165nM). TR-7 showed lower affinity for H-4 receptors (K-i=203nM) and IC(50)of 512nM. Conclusions and Implications We describe a therapeutic use for new H-3 (E-162) and H-4 receptor (TR-7) antagonists in neuropathy. Targeting H-3 and H-4 receptors enhanced morphine analgesia, consistent with multimodal pain therapy.

One-pot multicomponent synthesis of piperidinium 3,3 ‘-(arylmethylene) bis (2-hydroxynaphthalene-1,4-diones): NMR spectroscopic and X-ray structure characterization

A facile synthesis of piperidinium 3,3’-(arylmethylene) bis (2-hydroxynaphthalene-1,4-dione) analogs as organic salts is described by the one-pot pseudo-four-component reaction between 2-hydroxy-1,4-naphthoquinone, aromatic aldehydes, and piperidine. The single-crystal X-ray diffraction analysis of these systems confirms that the stabilized predominant interactions are N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds. Mild and clean reaction conditions, high atom economy, and operational simplicity of this one-pot multicomponent reaction coupled with excellent yields and no need for column chromatography have transformed this procedure to be a superior synthetic route for the efficient formation of families of naphthoquinone-derived compounds.

Characterization of post-surgical critical patients with infections associated with healthcare after prolonged perfusion of remifentanil

INTRODUCTION: Healthcare associated infections (HAI) are the most frequent complication of hospitalized patients. The aim of this study was to describe the clinical and epidemiological characteristics of critically ill post-surgical patients with a diagnosis of healthcare associated infections, after a pattern of sedoanalgesia of at least 4 days. METHODS: All patients over 18 years of age with a unit admission of more than 4 days were consecutively selected. The study population was the one affected by surgical pathology where sedation was based as analgesic the opioid remifentanil for at least 96 hours in continuous perfusion. Patients who died during admission to the unit and those with combined analgesia (peripheral or neuroaxial blocks) were excluded. Data analysis was performed using the statistical package Stata version 7.0. RESULTS: The patients admitted to the Post-Surgical Critical Care Unit (PCU) during study were 1789 and the population eligible was comprised of 102 patients. 56.86% of patients suffered IACS. The most frequent IACS was pneumonia associated with mechanical ventilation (30.96 per 1000 days of mechanical ventilation), Pseudomonas aeruginosa being the most frequently isolated germ. The germs with the greatest involvement in multiple drug resistance (MDROs)were enterobacteria, mainly Klebsiella pneumoniae resistant to extended-spectrum beta-lactamases (ESBL). CONCLUSIONS: Pneumonia associated with mechanical ventilation is the most prevalent HAI and Pseudomonas aeruginosa is the main etiological agent. The groups of antibiotics most frequently used were cephalosporin and aminoglycosides. It is necessary to implement the prevention strategies of the different HAI, since most of them are avoidable.

Functionalization of Piperidine Derivatives for the Site-Selective and Stereoselective Synthesis of Positional Analogues of Methylphenidate

Rhodium-catalyzed C-H insertions and cyclopropanations of donor/acceptor carbenes have been used for the synthesis of positional analogues of methylphenidate. The site selectivity is controlled by the catalyst and the amine protecting group. C-H functionalization of N-Boc-piperidine using Rh-2(R-TCPTAD)(4), or N-brosyl-piperidine using Rh-2(R-TPPTTL)(4) generated 2-substitited analogues. In contrast, when N-alpha-oxoarylacetyl-piperidines were used in combination with Rh-2(S-2-Cl-5-BrTPCP)(4), the C-H functionalization produced 4-susbstiuted analogues. Finally, the 3-substituted analogues were prepared indirectly by cyclopropanation of N-Boc-tetrahydropyridine followed by reductive regio- and stereoselective ring-opening of the cyclopropanes.

The reactions of chlorine dioxide with inorganic and organic compounds in water treatment: kinetics and mechanisms

Chlorine dioxide (ClO2), as an alternative to chlorine, has been widely applied in water treatment. In order to better understand the performance of ClO(2)in water treatment, the kinetics and mechanisms of ClO(2)reactions with inorganic and organic compounds found in waters are critically reviewed. In the case of inorganic compounds, ClO(2)reacts with I-, CN-, NO2-, SO32-, Fe(ii) and Mn(ii) rapidly at apparent second-order reaction rate constants (k(app)) of 10(2)-10(6)M(-1)s(-1)at pH 7.0 and barely reacts with NH(4)(+)and Br-. In the case of organic compounds, ClO(2)selectively reacts with compounds with electron-rich moieties, such as phenols (k(app)= 10(3)-10(9)M(-1)s(-1)), anilines (k(app)= 10(5)-10(8)M(-1)s(-1)), and thiols (k(app)> 10(8)M(-1)s(-1)). ClO(2)also shows high reactivity towards aliphatic tertiary amines and heterocyclic nitrogenous compounds (i.e., indoles and piperidines) withk(app)of 10(1)-10(6)M(-1)s(-1)at pH 7.0, but low reactivity with unsaturated structures (i.e., olefins and aldehydes). Thek(app)values at pH 7.0 in ClO(2)oxidation vary over 14 orders of magnitude. Electron transfer is the dominant pathway for ClO(2)reactions. Quantitative structure-activity relationships (QSARs) can be used to predict the species-specific secondary reaction rate constants for ClO(2)oxidation of compounds containing phenolic and amine structures. Little modifications are expected on the structure of the parent compounds upon the primary attack of ClO2, but further oxidation generally leads to the formation of quinones, aldehydes and carboxylic acids. Furthermore, the transformation kinetics of inorganic compounds, typical organic compounds and emerging micropollutants are compared and their half-life times under typical water treatment conditions during ClO(2)oxidation are calculated.

Generation and Alkylation of alpha-Carbamyl Radicals via Organic Photoredox Catalysis

Strategies for the direct C-H functionalization of amines are valuable as these compounds comprise a number of pharmaceuticals, agrochemicals and natural products. This work describes a novel method for the C-H functionalization of carbamate-protected secondary amines via a-carbamyl radicals generated using photoredox catalysis. The use of the highly oxidizing, organic acridinium photoredox catalyst allows for direct oxidation of carbamate-protected amines with high redox potentials to give the corresponding carbamyl cation radical. Following deprotonation, the resultant open-shell species can be intercepted by a variety of Michael acceptors to give elaborate alpha-functionalized secondary amines. The reaction proceeds under mild conditions without the requirement of exogenous redox mediators or substrate prefunctionalization. Additionally, we were able to showcase the utility of this methodology through the enantioselective synthesis of the indolizidine alkaloid, (+)-monomorine I.
