Racemic mefloquinium chlorodifluoroacetate: crystal structure and Hirshfeld surface analysis

In the racemic title molecular salt, C17H17F6N2O+center dot C2ClF2O3-(systematic name: 2-{[2,8-bis(trifluoromethyl) quinolin-4-yl](hydroxy) methyl} piperidin-1-ium chlorodifluoroacetate), the cation, which is protonated at the piperidine N atom, has the shape of the letter, L, with the piperidin-1-ium group being approximately orthogonal to the quinolinyl residue [the C-q-C-m-C-m-N-a (q = quinolinyl; m = methine; a = ammonium) torsion angle is 177.79 (18)degrees]. An intramolecular, charge-assisted ammonium-N-H center dot center dot center dot O(hydroxyl) hydrogen bond ensures the hydroxy-O and ammonium-N atoms lie to the same side of the molecule [O-h-C-m-C-m-N-a (h = hydroxyl) = -59.7 (2)degrees]. In the crystal, charge-assisted hydroxyl-O-H center dot center dot center dot O- (carboxylate) and ammonium-N+-H center dot center dot center dot O-(carboxylate) hydrogen bonds generate a supramolecular chain along [010]; the chain is consolidated by C-H center dot center dot center dot O interactions. Links between chains to form supramolecular layers are of the type C-Cl center dot center dot center dot pi (quinolinyl-C-6) and the layers thus formed stack along the a-axis direction without directional interactions between them. The analysis of the calculated Hirshfeld surface points to the dominance of F center dot center dot center dot H contacts to the surface (40.8%) with significant contributions from F center dot center dot center dot F (10.5%) and C center dot center dot center dot F (7.0%) contacts.

Occupational Dermatoses Caused by Contact with Metalworking Fluids in the Region of Central Slovakia from 2000 to 2012

Metalworking fluids (MWFs) are a common cause of allergic and irritant contact dermatitis. MWFs being currently used are mostly water based, containing biocides, emulsifiers, and other additives. We performed a retrospective analysis of the etiology of the occupational dermatoses caused by metalworking fluids in three regions of Central Slovakia (population of approximately 2 million) between 2000 and 2012. The primary aim was the analysis of metalworking fluid-induced dermatoses, which involved determining the particular disease type (allergic or irritant), its regional distribution, and the specific chemical causing the disease. The secondary aim of the study was to assess the level of knowledge and competence among dermatologists in performing patch testing for allergens contained in metalworking fluids using a study-specific questionnaire. Of the total number of 422 dermatoses during the analyzed period, 64 (41 in men and 23 in women) were caused by metalworking fluids. The implicated fluids were all aqueous, synthetic MWFs. 39 patients developed an allergic and 25 an irritant-induced contact dermatitis. 51 patients were tested using a special Trolab (R) metalworking battery (Almirall Hermal GmbH, Reinbek, Germany).The test identified a positive reaction to one of the following chemicals: methylchoroisothiazolinone/methylisothiazolinone (MCl/MI), formaldehyde, 1,2-benzisothiazoline-3-one, abietic acid, chloroxylenol, triclosan, amerchol L101, dichlorophene, propylenglycol, metylene (bis-methyl oxazolidine), monoethanolamine, and diethanolamine. The questionnaire showed that a large majority of Slovak dermatologists have no experiences with testing of MWFs. Metalworking fluids were found to be the most frequent cause of occupational contact dermatitis. They also are the second largest group of all occupational dermotoses. Their incidence corresponded with the presence of machine industry in the region. Several unresolved problems include detection of specific allergens and standardization of patch test performance among individual dermatologists. Low levels of experience in testing of MWFs revealed need to educate both dermatologists and residents.

Oxazolidine Formation, or Loss of Acid, from Attempted Fluorination of Amide Side-Chain in 2-Nitroimidazoles

Reaction of Etanidazole (a 2-nitroimidazole derivative with an amide side-chain containing a hydroxyethyl group) with triflic anhydride gives, depending on conditions, a trifluoromethyl(sulfonyl)oxazolidine via a cyclization reaction, or a fluorine-free formate derivative; reaction with tosyl chloride gives only a chloroethyl derivative. An attempt to replace a Br-atom in a related propyl-containing amide side-chain by a F-atom forms instead a propylene derivative via loss of HBr. The studies stem from interest in use of 2-nitroimidazoles with fluorine-containing amide side-chains as hypoxia markers.

HPLC-UV method for evaluation of inhibitors of plasma amine oxidase using derivatization of an aliphatic aldehyde product with TRIS

Plasma amine oxidase (PAO), which is also designated as semicarbazide-sensitive amine oxidase (SSAO), copper-containing amine oxidase 3 (AOC3), or vascular adhesion protein-1 (VAP-1), catalyzes the oxidative deamination of primary amines to aldehydes using copper and a quinone as cofactors. Because it participates in the transmigration of inflammatory cells through the blood vessels into the tissue, PAO is attributed an important role in inflammatory diseases. Therefore, inhibitors of this enzyme could lead to new therapeutics for the treatment of inflammation-related conditions. Assays for the evaluation of PAO inhibitors usually measure the conversion of benzylamine to benzaldehyde by UV spectroscopy. We have developed a test system with the new substrate 6-(5-phenyl-2H-tetrazol-2-yl)hexan-1-amine, monitoring the formation of the enzyme product 6-(5-phenyl-2H-tetrazol-2-yl)hexanal by reversed phase HPLC with UV detection. Since this compound only eluted with poor peak shape due to hydrate formation in the aqueous mobile phase, it was derivatized with tris(hydroxymethyl)aminomethane (TRIS) under mild conditions to an oxazolidine prior HPLC analysis. The validation of the method revealed that the new substrate was bound with higher affinity to PAO and converted with higher velocity than the standard substrate benzylamine.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 90319-52-1. Formula: C9H9NO2.

Catalytic Reductive Aminolysis of Reducing Sugars: Elucidation of Reaction Mechanism

A catalytic reductive aminolysis of reducing monosaccharides into short ethylene diamines (or C-2 diamines) was recently communicated by our group (Pelckmans et al. Angew. Chem. Int. Ed. 2017, 56, 14540-14544). Here, a general mechanism for this novel reaction is proposed based on the results of a combined experimental and theoretical study. The mechanism involves hemiaminal formation and subsequent dehydration to produce a zwitterionic iminium intermediate, which undergoes fast C-C cleavage as a result of intramolecular deprotonation, followed by hydrogenation of the formed unsaturated amine intermediate. The role of the amine in facilitating the C-C scission is explained in detail and supported by DFT calculations. Different catalysts, carbohydrate substrates, and reaction conditions were tested to validate the proposed reaction mechanism. Reductive aminolysis of sugars is preferably carried out in the presence of a passivated silica(-alumina) supported Ni catalyst and an alkyl amine using 75-85 bar H-2 at 125-130 degrees C. The water content in the reaction mixture should be kept below 33 wt % to favor dehydration equilibria in the mechanism, while the amine-to-glucose molar ratio should be kept high, preferably larger than 6, to favor the amination equilibria. The reaction rate experiences a strong solvent dependency. For instance, the presence of MeOH enhances the rate of C-2 diamine formation, as compared to the use of tetrahydrofuran (THF). DFT calculations show that presence of MeOH beneficially affects both the kinetics of the nucleophilic amine attack and the C-C bond scission. These selective rate enhancements result in a 2- to 3-fold increase of the C-2 diamine yield. Among a series of aminating agents, reductive aminolysis with N-methylethanolamine (MEOA) shows a 92 C% yield to the corresponding C-2 diamine (BHEDMEDA). The high yield is explained by the formation of a heterocyclic oxazolidine intermediate. Since its formation occurs H-2 free, a two-step one-pot production protocol, decoupling C-C scission and hydrogenation, is proposed to achieve highest C-2 diamine yield.
