Glycomimetic Based Approach toward Selective Carbonic Anhydrase Inhibitors

The synthesis of selective inhibitors of human carbonic anhydrases (hCAs) is of paramount importance to avoid side effects derived from undesired interactions with isoforms not involved in the targeted pathology, and this was partially addressed with the introduction of a sugar moiety (the so-called sugar approach). Since glycomimetics are considered more selective than the parent sugars in inhibiting carbohydrate-processing enzyme, we explored the possibility of further tuning the selectivity of hCAs inhibitors by combining the sulfonamide moiety with a sugar analogue residue. In particular, we report the synthesis of two novel hCAs inhibitors 2 and 3 which feature the presence of a piperidine iminosugar and an additional carbohydrate moiety derived from levoglucosenone (1), a key intermediate derived from cellulose pyrolysis. Biological assays revealed that iminosugar 2 is a very strong inhibitor of the central nervous system (CNS) abundantly expressed hCA VII (K-I of 7.4 nM) and showed a remarkable selectivity profile toward this isoform. Interestingly, the presence of levoglucosenone in glycomimetic 3 imparted a strong inhibitory activity toward the tumor associated hCA IX (K-I of 35.9 nM).

Multifunctional arylsulfonamide derivatives with 5-HT6/5-HT7 receptor antagonistic activity: a structural study

Nowadays, a search for antagonists co-acting on serotonin receptor subtypes 6 and 7 (5-HT6R and 5-HT7R, respectively) is of great interest due to the increasing number of patients suffering from dementia and related behavioural and psychological symptoms. The X-ray crystal structures of four promising multifunctional ligands in the hydrochloride forms were determined, namely 4-(6-fluoro-1,2-benzoxazol-3-yl)-1-[3-(3-methylbenzenesulfonamido) propyl]piperidin-1-ium chloride, C22H27FN3O3S+center dot Cl-, (I), 4-(6-fluoro-1,2-benzoxazol-3-yl)-1-[4-(5-fluoro-3-methylbenzo[b]thiophene-2-sulfonamido) butyl] piperidin-1-ium chloride, C25H28F2N3O3S2+Cl-, (II), 4-(6-fluoro-1,2-benzoxazol-3-yl)-1-[4(6-fluorobenzo[b]thiophene-2-sulfonamido)butyl] piperidin-1-ium chloride, C24H26ClFN3O3S2+center dot Cl-, (III), and 4-(6-fluoro-1,2-benzoxazol-3-yl)-1-[3-(3-chloro4-fluorobenzenesulfonamido)propyl] piperidin-1-ium chloride, C21H22ClF2N3O3S2+center dot Cl-, (IV). Two pharmacologically important functional groups, i.e. arylsulfonamide and piperidinyl-fluorobenzisoxazole, are linked by three- and four-membered aliphatic chains. These compounds crystallize as hydrochloride salts in monoclinic space groups, i.e. C2/c for (I), P2(1)/c for (II) and (III), and P2(1/n) for (IV). In the asymmetric unit, a charge-assisted hydrogen bond is observed between the cation located at the piperidine N atom and the chloride anion. The protonated piperidine N atom is critical to the pharmacological activity for the compounds, allowing for a strong interaction with monoaminergic receptors in the central nervous system. The sulfonyl group plays the role of a hydrogen-bond acceptor in the pharmacophore model and is involved in several C-H center dot center dot center dot O interactions. Two aromatic fragments of the presented structures are involved in C-H center dot center dot center dot pi contacts, which were studied by Hirshfeld structure analysis. The distances between the mentioned functional groups are in agreement with pharmacophore models given in the literature. The studied interactions observed in the crystal structure indicate the main forces responsible for ligand-receptor recognition and binding.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 124172-53-8, in my other articles.

Four xanthenyl-derived compounds: a comparative investigation of their host behaviour in the presence potential saturated and unsaturated heterocyclic six-membered ring guest solvents

Four xanthenyl-derived host compounds, namely trans-N,N ‘-bis(9-phenyl-9-xanthenyl)cyclohexane-1,4-diamine (1,4-DAX), trans-N,N ‘-bis(9-phenyl-9-thioxanthenyl)cyclohexane-1,4-diamine (1,4-DAT), N,N ‘-bis(9-cyclohexyl-9-xanthenyl)ethylenediamine (OED) and N,N ‘-bis(9-cyclohexyl-9-thioxanthenyl)ethylenediamine (SED) were assessed for their selectivity behaviour in the presence of both the saturated and unsaturated heterocyclic six-membered ring guest solvents morpholine (MOR), piperidine (PIP), dioxane (DIO) and pyridine (PYR). Related compounds OED and SED behaved similarly when each was recrystallized from mixtures of these guests, both selecting for MOR and discriminating against PYR, while, surprisingly, the performance of structurally-similar 1,4-DAX and 1,4-DAT in equivalent conditions, on the other hand, was entirely contrasting: only 1,4-DAX formed complexes from such guest mixtures and 1,4-DAT failed to do so in each instance. Furthermore, 1,4-DAX preferred PYR, an observation distinct from that of OED and SED. Single crystal diffraction (SCXRD) experiments were carried out on suitable crystals formed by 1,4-DAX with these guests, and it was revealed that the preference for PYR may be attributed to both host-guest pi-pi interactions and a shorter H-bond between molecules of the host and PYR compared with other complexes. SCXRD experiments were not possible for OED, SED and 1,4-DAT owing to either the inability of the host compound to complex with these guests or poor crystal quality of the resultant complexes.

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.

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.

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.

A series of novel pyridine-connected piperidine derivatives (2a-g) and pyridine-connected 2H-thiopyran derivatives (4a-g) were synthesized and evaluated for larvicidal, nematicidal, and antimicrobial activities. Compound 4e exhibited larvicidal activity against second instar larvae with an LD50 value of 0.8 mu g/mL. In addition, 4e was most effective against root knot nematode Meloidogyne javanica, with an LD50 value of 3.2 mu g/mL. Compounds 2e (MIC: 4 mu g/mL) and 2d (MIC: 4 mu g/mL) exhibited high antibacterial activity against Klebsiella pneumonia, and Escherichia coli, respectively. Compounds 4b (MIC: 0.25 mu g/mL) and 4f (MIC: 2 mu g/mL) showed high antifungal activity against Candida albicans and Microsporum audouinii, respectively. Therefore, overall activity profiles envisages that compounds 2e, 2d, 4e, 4b, and 4f could be employed for the development of new classes of drugs with larvicidal, nematicidal, and antimicrobial activities.

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.
