In the reaction of 2,6-dichloropyridine and 2,6-dichloro-3-phenylpyridine with potassium amide in liquid ammonia at -70°C, formation of derivatives of 4,4-bipyridyl and 3,4-bipyridyl is observed. The 4,4 coupling products are far in excess to the 3,4 coupling products. When the reaction is carried out at -70°C in the presence of potassium permanganate, the corresponding 4-aminopyridines are the main products. 2-Chloro-6-phenoxypyridine is very unreactive with this aminating reagent at -70°C as well as -33°C, but in the presence of potassium permanganate at -33°C 4-amino-2-chloro-6-phenoxypyridine is formed in fair yield. The mechanisms of the formation of the bipyridyls and 4-aminopyridines are presented.. ...

Rationale Roflumilast is an investigational PDE4 inhibitor for potential asthma therapy. Inhibitory effects of roflumilast on allergen-induced early airway response (EAR), late airway hyperresponsiveness (AHR), and inflammatory cells were investigated in a fungal allergen model of asthma in BALB/c mice. Methods Mice were sensitized with Aspergillus fumigatus extract (Afu) and adjuvant (i.p. and s.c. both on Day 0). After 2 inhalation boosts with Afu aerosol on Days 14 and 21, animals were Afu aerosol challenged on Day 23. Before each Afu aerosol exposure, animals received i.g. 1mg/kg or 5mg/kg roflumilast. For EAR, lung resistance was measured by body plethysmography in orotracheally intubated mice. AHR against aerosolized methacholine was determined 24 h after challenge by head-out plethysmography. Bronchoalveolar lavage (BAL) was done 25 h after challenge and differential cell count was determined. Results Afu-sensitized and -challenged mice showed pronounced EAR, AHR, and pulmonary ...

Abstract : 2-Aminopyridine (2-AP) and 2,6-diaminopyridine (2,6-DAP) are two derivatives of aminopyridines that act as animportant organic intermediates, mostly used in medicines, dyes and organic sensors. The aim of the study was to evaluate theimpact of biofield energy treatment on isotopic abundance ratios of 2H/1H, 13C/12C, or 15N/14N, in aminopyridine derivativesusing gas chromatography-mass spectrometry (GC-MS). The 2-AP and 2,6-DAP samples were divided into two parts: controland treated. The control sample remained as untreated, while the treated sample was further divided into four groups as T1, T2,T3, and T4. The treated group was subjected to Mr. Trivedis biofield energy treatment. The GC-MS spectra of 2-AP and 2,6-DAP showed five and six m/z peaks respectively due to the molecular ion peak and fragmented peaks of aminopyridinederivatives. The isotopic abundance ratio of 2H/1H, 13C/12C, or 15N/14N were calculated for both the derivatives and significantalteration was found in the ...
Methapyrilene is an antihistamine and anticholinergic of the pyridine chemical class which was developed in the early 1950s. It was sold under the trade names Co-Pyronil and Histadyl EC.[1] It has relatively strong sedative effects, to the extent that its primary use was as a medication for insomnia rather than for its antihistamine action. Together with scopolamine, it was the main ingredient in Sominex, Nytol, and Sleep-Eze. It also provided the sedative component of Excedrin PM. All of these products were reformulated in the late 1970s when methapyrilene was demonstrated to cause liver cancer in rats when given chronically.[2] ...
Aminopyridines have recently become the focus of extensive studies, mainly because of their wide use as building blocks for synthetic transformations (Peng et al., 2001; Leung et al., 2002). Carboxylic acids are important in crystal engineering due to their strong and directional O-H···O and N-H···O hydrogen bonds; this is the main hydrogen-bonding motif often encountered in carboxylic acid-amine complexes (Banerjee & Murugavel, 2004; Lautie & Belabbes, 1996). Here, we report the synthesis and crystal structure of the title compound, (I).. The asymmetric unit of the title compound, (Fig 1), contains one 2,3-diaminopyridinium cation, one sorbate anion and one neutral sorbic acid molecule. The 2,3-diaminopyridinium cation is planar with a maximum deviation of 0.013 (2) Å for atom C2. Protonation of atom N1 has resulted in a slight increase in the angle C1-N1-C5 [123.71 (17)°]. The sorbate anion and sorbic acid moiety is in the EE configuration. The structure is significantly different ...

Amlexanox is the active ingredient in a common topical treatment for recurrent aphthous ulcers of the mouth (canker sores),[2] reducing both healing time[3] and pain.[4] Amlexanox 5% paste is well-tolerated,[5] and is typically applied four times per day directly on the ulcers.[3] A 2011 review found it to be the most effective treatment of the eight treatments investigated for recurrent canker sores.[6] It is also used to treat ulcers associated with Behçet disease.[7]. In Japan, it is used to treat bronchial asthma, allergic rhinitis and conjunctivitis.[8]. Although it is one of the only effective treatments known for apthous stomatitis, the company that claims to have the rights to the drug, Uluru Inc., is either unwilling or incapable of manufacturing it. The company has not responded to patients who have pleaded for help in obtaining the medication for relief from this often debilitating condition.. ...

Lawrence LeBlond for redOrbit.com - Your Universe Online. A drug that is normally prescribed for asthma patients is breathing new life as a potential treatment option for people who suffer from diabetes and obesity. The drug, amlexanox, was demonstrated to reverse obesity, diabetes and fatty liver in mice in a new study, published this week in the journal Nature Medicine.. The finding comes from the research lab of Alan Saltiel, the Mary Sue Coleman director of the Life Sciences Institute at the University of Michigan. Saltiel explained that amlexanox is currently prescribed to treat asthma in Japan and canker sores in the US, but the new research shows that it may also be a viable option for treatment of obesity and diabetes.. One of the reasons that diets are so ineffective in producing weight loss for some people is that their bodies adjust to the reduced calories by also reducing their metabolism, so that they are defending their body weight, Saltiel said in a statement. Amlexanox seems ...

AU - Ramakrishnan, Sundaram. AU - Loh, H. H.. PY - 1996/10/22. Y1 - 1996/10/22. N2 - Somatostatin and other neuropeptides are known to modulate the proliferative capacity of immune cells. In the present study, we investigated the expression of Somatostatin receptor (SSTR) subtypes on rat thymocytes. RT-PCR analysis of fresh thymocytes showed significant levels of transcripts for the SSTR2 whereas transcripts for the SSTR1 and SSTR3 were not detectable. Interestingly, when the thymocytes were activated with low concentration of Phytohemagglutinin and interleukin 1, the transcript for SSTR1 was markedly increased. Lymphokine induced activation of thymocytes selectively upregulated the SSTR1 since, transcripts for SSTR2 remained the same after activation and SSTR3 was not detectable. PCR amplified fragment of SSTR1 from the ...
There is limited real-world evidence of the demographic and clinical characteristics, as well as resource utilizations and associated costs, among COPD patients who were on roflumilast vs other maintenance combination medications. Results from this study indicate that, at baseline, most patients in the roflumilast cohort use roflumilast along with other maintenance medications as combination therapy. The roflumilast cohort showed a larger proportion of patients with ,3 drug classes in their combination therapy, a greater comorbidity burden, more severe COPD conditions, and higher exacerbation history compared with the nonroflumilast cohort. These results are not unexpected. Roflumilast is a relatively new drug indicated for the treatment of severe COPD, and previous research has suggested that newer drugs are more likely to be prescribed to patients who have failed to respond to other treatments, tend to be sicker, or both (Schneeweiss 2011). In addition, the GOLD guidelines recommend adding ...

We review the latest literature on the neuropharmacological treatments for acquired nystagmus. Nystagmus may have a significantly impact on health, yet there is little scientific evidence on which to make firm recommendations for treatment. Acquired pendular nystagmus may respond to gabapentin or memantine; downbeat and upbeat nystagmus to aminopyridines; and periodic alternating nystagmus to baclofen. To improve treatment we need multi-centre, randomised controlled trials using standardised techniques in reporting objective outcomes, with good follow-up duration and careful reporting of side effects.. ...

Roflumilast has been shown to reduce exacerbations in patients at risk of these episodes, but whether this occurs on top of the effect of other therapy has been less clear. In this pre-specified combined analysis of data from two large randomised clinical trials, roflumilast decreased the rate of COPD exacerbations and improved lung function (pre- and post-bronchodilator FEV1) despite concomitant treatment with LABAs. In addition, the time to onset of the first, second and third moderate or severe exacerbation was delayed by roflumilast regardless of concomitant LABA use, while the frequency of adverse events associated with roflumilast treatment was not different in those with or without LABAs. The relative reduction in moderate or severe exacerbation rates in patients treated with LABAs was 20.7% and the corresponding number needed to treat with roflumilast to prevent one moderate or severe exacerbation per year was low (3.2).. Although the treatment effect of roflumilast together with ...

The goal of this clinical research study is to learn if BKM120 (buparlisib) can help to control glioblastoma and/or gliosarcoma. Researchers also want to learn more about how much study drug is in different areas of the body at different time points. The safety of this drug will also be studied. BKM120 is designed to block a protein that is important to the growth and division of cancer cells, which may cause the cells to die.
While Roflumilast is an established drug for the reduction of COPD exacerbations, its mechanism in the lungs, particularly its anti-inflammatory activities, are not well understood. Better understanding of its effects on inflammatory cells and the inflammatory cascade may result in a better understanding which patients would benefit most from a treatment with Roflumilast and which measurable parameters might serve as surrogate predictors for the clinical efficaciousness of Roflumilast ...
The aim of the study is to investigate the efficacy of the drug roflumilast for the treatment of mild cognitive impairment (MCI). We are comparing the efficacy of roflumilast with that of a placebo. A placebo is a drug without an active ingredient, a fake drug. With an increasingly aging population, more and more people are having problems with their memory, attention, language or learning ability: known as cognition for short. The possibilities of treating people with these complaints are limited. For this reason we are looking for ways to reduce these symptoms by treating them with a drug. In this study we will investigate in people with mild memory problems whether a 6-month treatment with roflumilast improves memory and attention. Furthermore, we are also interested in the views of the patients informal caregiver.. ...

Roflumilast is a targeted, oral, once-daily administered phosphodiesterase 4 (PDE4) inhibitor with clinical efficacy in COPD. Results from in vitro studies with roflumilast indicate that roflumilast has anti-inflammatory properties that may be applicable for the treatment of COPD. In this cross-over study, 38 patients with COPD (mean (SD) age 63.1 (7.0) y, post-bronchodilator FEV1 61.0 (12.6) %predicted) received 500 μg roflumilast or placebo once daily for 4 weeks. Induced sputum samples were collected prior to and after 2 and 4 weeks of treatment. Differential and absolute cell counts were determined in whole sputum samples. Markers of inflammation were determined in sputum supernatants and blood. Spirometry was performed weekly. Roflumilast significantly reduced the absolute number of neutrophils and eosinophils per gram of sputum, compared with placebo, by 35.5% (95%CI 15.6, 50.7; p=0.0017) and 50.0% (26.8, 65.8; p=0.0005), respectively.

Molecular imprinted polymer against nicotine was prepared and its binding affinity and selectivity to nicotine were evaluated by batch adsorption experiments. Nicotine-imprinted polymer exhibited higher affinity to nicotine compared to non-imprinted polymer; Scatchard analysis indicated that there were two classes of recognition sites in nicotine-imprinted polymer, which had different affinity to nicotine. Furthermore, compared to the adsorption behaviors of aminopyridines, nicotine-imprinted polymer displayed satisfying selectivity. The results in this study proved the possibility to selectively extract nicotine from tobacco smoke when the nicotine-imprinted polymer was used as solid-phase extraction material.

Purpose: Cetuximab, an antibody targeting the epidermal growth factor receptor (EGFR), is active in colorectal cancer (CRC). However, response rates range from only 10% to 20%. Here, we investigate hepatocyte growth factor (HGF)-dependent mesenchymal-epithelial transition factor (MET) activation as a mediator of cetuximab resistance through signal diversification in CRC cell lines. Experimental Design: DiFi, GEO, and LIM1215 cells were treated with varying concentrations and combinations of EGF, HGF, cetuximab, and PHA-665752 (a highly specific MET kinase inhibitor). Biological end points included proliferation, cell-cycle arrest, and apoptosis. Proliferation was measured using WST-1 assays and synergy investigated via isobolograms. Expression and signaling were examined using immunoblotting. Results: EGFR and MET are co-expressed in these CRC cell lines, and dual receptor activation synergistically increased proliferation. Cetuximab inhibited cell growth by 60% to 80%, with an associated ...
BACKGROUND: Tramadol is an opioid analgesic licensed for use in moderate to severe pain. It is considered as a low risk for abuse, so control regulations are not as stringent as for strong opioids such as morphine. It has a potential role as a step 2 option of the World Health Organization (WHO) analgesic ladder. OBJECTIVES: To assess the benefits and adverse effects of tramadol with or without paracetamol (acetaminophen) for cancer-related pain. SEARCH METHODS: We searched the following databases using a wide range of search terms: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and LILACS ...
