The 1,3-dipolar cycloaddition reaction of cyclopropanes and nitrones to give tetrahydro-1,2-oxazine has been studied with density functional theory calculations at the B3LYP/6-31+G(d,p) level of theory. Realistic substituents were modelled including those at the 2-, 3-, 4-, and 6-positions of the final oxazine ring product. The strained σ bond of the cyclopropane was found to play the role of an alkene in a conventional [3+2] dipolar cycloaddition. Two distinct, but similar, reaction mechanisms were found †an asymmetric concerted pathway and a stepwise zwitterionic pathway. The reaction barriers of the two pathways were nearly identical, differing by less than ~1 kcal/mol, no matter what the substituents were. The effect of a Lewis acid catalyst was examined and found to have a very large effect on the calculated barriers through coordination to the carbonyl oxygen atoms of the diester substituents on the cyclopropane. The reaction barrier was found to decrease by as much as ~19 ...

Anticonvulsive and neuroprotective effects of (2S,1R,2R,3R)-2-(2,3-dicarboxycyclopropyl) glycine (DCG-IV), a potent agonist for Group II metabotropic glutamate receptors, were examined in vivo against the excitotoxicity of kainic acid in the rat. Intraventricular injection of kainic acid (2 nmol) …

The structure of cord factor was studied in several strains of Mycobacterium simiae, including habana TMC 5135, considered as highly immunogenic in experimental tuberculosis and leprosy. The mycolic acids liberated from cord factor were identified in all cases as α′-, α- and keto-mycolates. According to the general NMR and MS data, α′-mycolates were mono-unsaturated and contained from 64 to 68 carbon atoms, whereas α-mycolates mainly presented two 2,3-disubstituted cyclopropane rings and a chain length of 80-91 carbon atoms; keto-mycolates mostly contained one cyclopropane ring and 85-91 carbon atoms. Taking into account the 1H-NMR results, strains varied in the ratio of the different mycolates, and the high levels of keto-mycolates found in the cord factors of TMC 5135 and ATCC 25275T stood out. Notably, MS revealed that the odd carbon number series of α-mycolates (C87-C89) predominated in the cord factor of TMC 5135, in contrast to the remaining studied strains, in which the even (C84-C86)

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. The relative proportion of sputum neutrophils and ...

Roflumilast is a product which has been approved for the treatment of severe chronic obstructive lung disease (COPD) and its approved dose is 500μg once daily. This study is primarily designed to see whether alternation in this dose can improve tolerability of Roflumilast in COPD patients. Therefore one in three patients will start roflumilast therapy at a lower dose of 250μg once daily, another one in three will only take the 500μg tablet every other day (and one placebo every other day). Rest of them will start the regular dose of 500μg once daily right away and see whether starting with a lower dose of Roflumilast will lead to better tolerability. Furthermore, the study will see if patients who do not tolerate roflumilast should be given a lower dose of 250μg once daily.. Lastly, the study will investigate what the body does to roflumilast. Patients with a history of COPD for at least last 12 months and a former smoker or current smoker with history of at least 10 pack years will be ...

Figure 1. M06-2x/6-31G(d) optimized geometries of 1 and 2.. They show that the geometry of 2 exhibits a structure that has two different C-C distances: one between the spiro carbons, and the second between the spiro carbon and the methylene carbon. The distance between the spiro carbons is rather short (1.458 Å), suggesting that the bonding here is between carbons that are nearly sp2-hybridized.. Lastly, they discuss the thermodynamics of polytriangulane. They employ a series of homodesmotic reactions to attempt to determine the enthalpy for adding another cyclopropyl ring to an extended triangulane. Unfortunately, the computed enthalpy is quite dependent on functional used. Similar attempts to define the strain energy is also flawed in this way. However, regardless of the functional the enthalpy for adding a cyclopropane ring appears to reach an asymptote rather quickly. So, using [3]triangulane they estimate that the strain energy per mole of cyclopropane in triangulane is about 42.7 kcal ...

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 ...

Tween® 80 is a frequently used supplement of media for the cultivation of lactic acid bacteria. We investigated its effect on the cell physiology and stress tolerance of Lactobacillus (L.) plantarum. Data on the transcriptomic response to Tween 80 supplementation and its effects on cellular fatty acid profiles and growth characteristics are compared with data characterizing the effect of Tween 80, other Tween types and free fatty acids on the high hydrostatic pressure (HHP) tolerance of L. plantarum strain TMW 1.708. These include effects on cell viability, sub-lethal injury, metabolic activity, protein release and propidium iodide uptake. Tween 80 caused the downregulation of fatty acid biosynthesis and an increase in oleic acid and cyclopropane fatty acid levels in the cell membrane. Tween 20, Tween 80 and free oleic acid, but not Tween 40, Tween 60 and other free fatty acids, conferred resistance against HHP. Tween 80 diminished pressure-induced loss of metabolic activity, protein release and uptake

For the past 40 years, dermatologists have safely used contact sensitizers such as dinitrochlorobenzene (DNCB), diphenylcyclopropenone (DPCP), and squaric acid dibutylester (SADBE) for the treatment of warts, alopecia areata, and even skin cancers. Most of these studies have utilized these powerful topical immunomodulators in acetone, a volatile solvent that precludes development of contact sensitizers as products. We have overcome these problems and stabilized these topical immunomodulators in a non-volatile, nonirritating GRAS (generally regarded as safe) vehicle. The current review article covers the traditional use of contact sensitizers for a variety of benign and malignant conditions and discusses possible mechanisms in relation to developments in modern molecular immunodermatology.

Like many of the molecular species that have been detected in the interstellar medium, the singlet carbene cyclopropenylidene (C3H2) has been presumed to be too unstable to isolate in the laboratory. However, by appending pi-electron-donating amino groups to the triangular skeleton, we prepared a cyclopropenylidene derivative that is stable at room temperature. In contrast to previously isolated carbenes, this compound does not require a heteroatom adjacent to the electron-deficient carbon to confer stability. Despite the presence of amino groups, the geometric parameters of the cyclic skeleton, revealed by x-ray crystallography, are only slightly perturbed relative to those of the calculated structure of unsubstituted cyclopropenylidene. Stable cyclopropenylidene derivatives might thus serve as models for a better understanding of the formation of carbon-bearing molecules in the interstellar medium ...

Dihalocarbenes were added to allenes to form dihalo-methylene- cyclopropanes which were then converted by the n-butyl lithium method to cumulenes. Both dichloro- and dibroraocarbenes were found to add to the allene double bond with the highest number of alkyl substituents. Propargyl alkenylmalonates were prepared in good yields and pyrolised under carefully controlled conditions to give allenic alkylidenemalonates in fair yields by Cope Rearrangement, but gave fission products under more extreme conditions. The position of the alkyl substituents on the alkenylmalonate group seemed to influence the ease of the rearrangement. Cyclopropanes were prepared in good yields from different types of x, b-unsaturated esters by the dimethylsulphozonium methylide reaction in dimethyl sulphoxide and dimethylformamide solvents. An Allentc ester, on the other hand, gave an unstable complex postulated as dimethylsulphoxonium 3-ethozycarbonyl 2-methylallylide. The syntheses of the only two naturally-occurring ...

Xiao-Chen Wang of Nankai University used 16 to rearrange the cyclopropane 15 to the alkene 17 (Angew. Chem. Int. Ed. 2017, 56, 4028. ). Hegui Gong of Shanghai University showed that even a tertiary halide such as 18 could participate in allylic coupling with 19, leading to 20 (Angew. Chem. Int. Ed. 2017, 56, 13103. ). Organopalladium intermediates are usually subject to rapid β-hydride elimination. Rui Shang and Yao Fu of the University of Science and Technology of China found that under blue light irradiation, even the tertiary halide 22 could participate in Heck coupling with 21 to give 23 (J. Am. Chem. Soc. 2017, 139, 18307. ). Lor nd Kiss and Ferenc F l p of the University of Szeged demonstrated that the chelating ability of the amide of 24 enabled selective cross metathesis with 25, leading to 26 (Eur. J. Org.

The ADME characteristics were investigated by the oral and IV routes in the rat. The bioavailability after the oral low and high doses were , 100% and approximately 50%, respectively. However, the bioavailability for the high dose was calculated using a lower IV dose. In addition, less than 1% of the parent compound was found in the faeces after the oral high dose, indicating practically complete absorption from the gastrointestinal tract. Therefore, 100% absorption by the oral route is assumed and is taken forward to risk characterisation. No sex difference was observed in blood kinetics at the low dose, however, in the high dose group, Cmax and AUC were higher in females than males. The elimination half life was 99-113 hours, irrespective of the dose, route or sex. The retention of radioactivity was low, with the majority (60%) of the radioactivity excreted by biliary route within 3 days of dosing. Approximately 20% was excreted in urine and a small amount of radioactivity exhaled as14CO2. ...

A series of studies is presented in which microwave spectra are obtained for various hydrogen-bonded, gas phase complexes between small hydrocarbons and hydrogen halides or HCN. The pulsed Fourier-transform, Fabry-Perot technique is used allowing nuclear quadrupole coupling and other various hyperfine interactions to be observed in addition to the normal rotational spectra. Details of structure and binding are elucidated for the complexes from zero-field spectroscopic constants. Observation of the rotational Zeeman effect for complexes involving cyclopropane gives additional electronic distribution information for the complexes and is shown to indirectly give magnetic properties for cyclopropane. The complexes discussed include complexes between cyclopropane and HCl, HF, and HCN and complexes between ethylene or acetylene and HCl or HCN. Also, the extension of the pulsed Fourier-transform, Fabry-Perot microwave technique to study electronically excited triplet states is discussed ...

They carried out DSC studies on the cyclopropane and on the bromodiene. The first step involves dibromocarbene addition to the but-2-ene and noted that the cyclopropane decomposes at an onset temperature of 145°C releasing 360 J/g and the diene at 226°C delivering 500 J/g. Both non-trivial amounts of energy. According to their SOPs a 100°C difference between onset temperature and reaction temperature must be observed for a decent safety margin to be maintained. To get around this problem two thing were done a) the dibromocyclopropane was isolated and b) the conversion to the bromodiene was carried out in a continuous flow reactor. A further complication is that the dibromocyclopropane is sensitive to basic conditions and careful work-up conditions had to be chosen to avoid high pH. Using t-BuOK/CHBr3 in heptanes the reaction was addition controlled at 0°C and gave a 98% yield of the diene precursor.. It was determined that the bromodiene was optimally synthesised by using a reaction ...

Hydroboration of alkenes is a classical reaction in organic synthesis in which alkenes react with boranes to give alkylboranes with subsequent oxidation resulting in alcohols. The double bond (π-bond) of alkenes can be readily reacted with boranes owing to its high reactivity. However, the single bond (σ-bond) of alkanes has never been reacted. To pursue the development of σ-bond cleavage, we selected cyclopropanes as model substrates since they present a relatively weak σ-bond. Herein, we describe an iridium-catalyzed hydroboration of cyclopropanes, resulting in β-methyl alkylboronates. These unusually branched boronates can be derivatized by oxidation or cross-coupling chemistry, accessing designer products that are desired by practitioners of natural product synthesis and medicinal chemistry. Furthermore, mechanistic investigations and theoretical studies revealed the enabling role of the catalyst.. ...

CL(14:0/14:0/18:1(11Z)/22:0) is a cardiolipin (CL). Cardiolipins are sometimes called a double phospholipid because they have four fatty acid tails, instead of the usual two. CL(14:0/14:0/18:1(11Z)/22:0) contains two chains of tetradecanoic acid at the C1 and C2 positions, one chain of (11Z-octadecenoyl) at the C3 position, one chain of docosanoic acid at the C4 position. While the theoretical charge of cardiolipins is -2, under normal physiological conditions (pH near 7), the molecule may carry only one negative charge. In prokaryotes such as E. coli, the enzyme known as diphosphatidylglycerol synthase catalyses the transfer of the phosphatidyl moiety of one phosphatidylglycerol to the free 3-hydroxyl group of another, with the elimination of one molecule of glycerol. In E. coli, which acylates its glycerophospholipids with acyl chains ranging in length from 12 to 18 carbons and possibly containing an unsaturation, or a cyclopropane group more than 100 possible CL molecular species are ...

Phytohormones are essential for integrating many aspects of plant development and responses to the environment. Regulation of hormonally controlled events occurs at multiple levels: synthesis, catabolism and perception (Trewavas 1983, Bradford and Trewavas 1994). At the level of perception, sensitivity to hormones can be regulated both spatially and temporally during the life cycle. An example of spatial regulation is the differential response to a hormone that occurs during organ abscission. Temporally, sensitivity of an organ to a hormone may change during maturation, as occurs during fruit ripening. In this review, we will focus on the initial event in recognition of one hormone, ethylene. The ethylene receptor was the first plant hormone receptor to be unambiguously identified. Over the last few years, great progress has been made in elucidating the genes involved in ethylene action. Nonetheless, the mechanisms of signal transduction remain to be established. Here, we will address the status ...

Cyclopropanetrione or trioxocyclopropane is a little-known oxide of carbon with formula C3O3. It consists of a ring of three carbon atoms each attached to an oxygen atom with a double bond. Alternately it can be thought as a trimer of carbon monoxide. This compound is thermodynamically unstable, and has not been produced in bulk. However it has been detected using mass spectrometry. It is the neutral equivalent of the deltate anion C3O32−, known since 1975. An equivalent hydrate hexahydroxycyclopropane or cyclopropane-1,1,2,2,3,3-hexol, (-C(OH)2-)3 also exists. This contains geminal hydroxy groups. Corkran, Greg; David W. Ball (2004). The relative energies of cyclopropanone, cyclopropanedione, and cyclopropanetrione.
