A Metabolomics Study of Retrospective Forensic Data from Whole Blood Samples of Humans Exposed to 3,4-Methylenedioxymethamphetamine: A New Approach for Identifying Drug Metabolites and Changes in Metabolism Related to Drug Consumption

The illicit drug 3,4-methylenedioxymethamphetamine (MDMA) has profound physiological cerebral, cardiac, and hepatic effects that are reflected in the blood. Screening of blood for MDMA and other narcotics are routinely performed in forensics analysis using ultra performance liquid chromatography with high-resolution time-of-flight mass spectrometry (UPLC-HR-TOFMS). The aim of this study was to investigate whether such UPLC-HR-TOFMS data collected over a two-year period could be used for untargeted metabolomics to determine MDMA metabolites as well as endogenous changes related to drug response and toxicology. Whole blood samples from living Danish drivers’ positive for MDMA in different concentrations were compared to negative control samples using various statistical methods. The untargeted identification of known MDMA metabolites was used to validate the methods. The results further revealed changes of several acylcarnitines, adenosine monophosphate, adenosine, inosine, thiomorpholine 3-carboxylate, tryptophan, S-adenosyl-L-homocysteine (SAH), and lysophospatidylcholine (lysoPC) species in response to MDMA. These endogenous metabolites could be implicated in an increased energy demand and mechanisms related to the serotonergic syndrome as well as drug induced neurotoxicity. The findings showed that it was possible to extract meaningful results from retrospective UPLC-HR-TOFMS screening data for metabolic profiling in relation to drug metabolism, endogenous physiological effects, and toxicology.

Electrochemical examination of mixed-ligand cobalt(III) complexes with tetraazamacrocyclic ligand and heterocyclic dithiocarbamates

Electrochemical stability of eight complexes of the general formula [Co(III)Rdtc(1-8)cyclam](ClO4)(2), where cyclam = 1,4,8,11-tetraazacyclotetradecane and Rdtc(-) (1-8) = 4-morpholine (Morphdtc), 4-thiomorpholine (Timdtc), 4-piperazine (Pzdtc), N-methyl piperazine (N-Mepzdtc), piperidine (Pipdtc), 2-, 3- or 4-methylpiperidine (2-, 3- or 4-Mepipdtc) dithiocarbamates, respectively, were studied. The substances were examined in aqueous NaClO4 solution and nonaqueous LiClO4 in CH3CN solution by cyclic voltammetry. In aqueous solution, macrocyclic ligand cyclam is characterized by the anodic peak at 0.95 V. The Rdtc(-) ligands have two anodic peaks, one in the region 0.25-0.30 V and the other in the 0.78-0.95 V region. Absence of these anodic peaks in the case of the complexes indicates that coordination to cobalt(III) stabilizes both cyclam and Rdtc(-) ligands, but reversible peaks in the range -0.68 to -0.78 V support the Co(III) redox reaction. In nonaqueous solutions cyclam has one anodic peak at 1.75 V. The ligands with heteroatom in the ring (Morphdtc, Timdtc, Pzdtc, N-Mepzdtc) have two anodic peaks, while the other four ligands (Pipdtc, 2-, 3- and 4-Mepipdtc) have only one anodic peak. In nonaqueous solution again, coordination to Co(III) ion stabilizes the Rdtc(-) ligands and contrary to aqueous solution no Co(III) redox reaction occurs, indicating a greater stability of the complexes in this media. Finally, the electrochemical results are compared with spectroscopic data obtained previously.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.If you’re interested in learning more about 35092-89-8. The above is the message from the blog manager. SDS of cas: 35092-89-8.

Polymer-Supported Stereoselective Synthesis of Benzoxazino[4,3-b][1,2,5]thiadiazepinone 6,6-dioxides

Herein, we report the stereoselective synthesis of trisubstituted benzoxazino[4,3-b]{1,2,5}thiadiazepinone 6,6-dioxides from polymer-supported Fmoc-Ser(tBu)-OH and Fmoc-Thr(tBu)-OH. After the solid-phase synthesis of N-alkylated-Nsulfonylated intermediates using various 2-nitrobenzenesulfonyl chlorides and bromoketones, the target compounds were obtained via trifluoroacetic acid (TFA)-mediated cleavage from the resin, followed by cyclization of the diazepinone scaffold. Except for the threonine-based intermediates, the inclusion of triethylsilane (TES) in the cleavage cocktail yielded a specific configuration of the newly formed C-3 chiral center. The final cyclization resulted in minor or no inversion of the C-12a stereocenter configuration.

Identification of a novel oxazolidinone (U-100480) with potent antimycobacterial activity

During the course of our investigations in the oxazolidinone antibacterial agent area, we have identified a subclass with especially potent in vitro activity against mycobacteria. The salient structural feature of these oxazolidinone analogues, 6 (U-100480), 7 (U-101603), and 8 (U-101244), is their appended thiomorpholine moiety. The rational design, synthesis, and evaluation of the in vitro antimycobacterial activity of these analogues is described. Potent activity against a screening strain of Mycobacterium tuberculosis was demonstrated by 6 and 7 (minimum inhibitory concentrations or MIC’s less than or equal to 0.125 mu g/mL). Oxazolidinones 6 and 8 exhibit MIC(90) values of 0.50 mu g/mL or less against a panel of organisms consisting of five drug-sensitive and five multidrug-resistant strains of M. tuberculosis, with 6 being the most active congener. Potent in vitro activity against other mycobacterial species was also demonstrated by 6. For example, 6 exhibited excellent in vitro activity against multiple clinical isolates of Mycobacterium avium complex (MIC’s = 0.5-4 mu g/mL). Orally administered 6 displays in vivo efficacy against M. tuberculosis and M. avium similar to that of clinical comparators isoniazid and azithromycin, respectively. Consideration of these factors, along with a favorable pharmacokinetic and chronic toxicity profile in rats, suggests that 6 (U-100480) is a promising antimycobacterial agent.

Synthesis of new quinoxaline derivatives by reductive cyclization of various 1-(2-nitrophenyl)-2-cyanoamines

The electrochemical cyanation of various six-membered N-(2-nitrophenyl) heterocyclic amines, including piperidine, morpholine, thiomorpholine, and N-Boc-protected piperazine derivatives, was investigated. The expected cyanoamines 5 were obtained in good yields and subjected to catalytic hydrogenation to afford the corresponding cyclic amidine N-oxides 6. The reductive cyclization proceeded through the formation of a hydroxylamine, which cyclized onto the cyano moiety. The stereoselectivity of the cyclization reaction was studied for the cases both of trans-5f, in which the substituent was axial and the 4-methyl substituent equatorial, and of cis-5f, in which both the 2-cyano and the substituents were equatorial. The expected tetrahydroquinoxalines 3 were conveniently prepared in a following step by the catalytic hydrogenation of cyclic amidines 6 in the presence of Pearlman’s catalyst at five atmospheres of hydrogen pressure.

Structure-reactivity correlations for complex formation reactions between square-planar metal centers and thioethers

Kinetics for complex formation between Pd(H2O)(4)(2+) and thioethers of largely varying electronic and steric properties, viz. MeSCH(2)COOH, (n-Pr)(2)S, EtSCH(2)CH(2)OH, S(CH2CH2CH2OH)(2), S(CH2CH2OH)(2), EtSCH(2)COOH, S(CH2COOH)(2), S(CH2CH2COOH)(2), (i-Pr)(2)S, (s-Bu)(2)S, (t-Bu)(2)S, and protonated thiomorpholine, S(C2H4)(2)NH2+, has been studied by use of stopped-flow spectrophotometry in an acidic aqueous medium. Second-order rate constants k(1)(298) are 1.61 x 10(4), 8.0 x 10(4), 3.79 x 10(4), 3.69 x 10(4), 2.21 x 10(4), 1.84 x 10(4), 1.91 x 10(3), 1.34 x 10(4), 1.52 x 10(4), 7.75 x 10(3), 900, and 5.2 x 10(3) M(-1) s(-1), respectively. The reactivity toward Pd(H2O)(4)(2+) of all thioethers studied so far can be described as a function of their sigma-donor properties as expressed by the sum of the Taft constants, Sigma sigma*, and their steric requirements as defined by cone angles, theta, by use of the equation: log k(1) = (9.9 +/- 0.3) – (0.67 +/- 0.05)Sigma sigma* – (0.059 +/- 0.003)theta. Similarly, second-order rate constants k(298) reported previously for reactions between thioethers and Pd(dien)H2O2+ and Pt(dienBr+ are described by log k(298) = (10.5 +/- 0.6) – 0.67 Sigma sigma* – (0.081 +/- 0.006)theta and log k(298) = (4.6 +/- 0.6) – 0.72 Sigma sigma* – (0.080 +/- 0.006)theta, respectively. Hence, the reactivity trends of thioethers toward square-planar complexes can be given a general interpretation in terms of intrinsic, electronic, and steric parameters, by use of log k = gamma + alpha Sigma sigma* + beta theta. Large variations in both electronic and steric properties of the entering ligands indicate that there is no ”duality behavior” in the reactions of thioethers with square-planar metal centers, as claimed in previous literature. No steric threshold is observed for these sterically unhindered systems. There is a rough compensation effect between Delta H-1 double dagger and Delta S-1 double dagger, i.e. a smaller Delta H-1 double dagger is usually accompanied by a larger negative Delta S-1 double dagger, indicating that all thioethers react via the same mechanism. It appears that the much lower reactivity observed for the highly branched (t-Bu)(2)S is primarily caused by a high activation enthalpy. Volumes of activation have been determined for a series of thioethers with a constant cone angle, viz. EtSCH(2)COOH, S(CH2COOH)(2), and S(CH2CH2COOH)(2) through high-pressure stopped-flow measurements. Values of Delta V-1 double dagger are -7.9 +/- 0.5, -8.1 +/- 0.4, and -7.6 +/- 0.3 cm(3) mol(-1), respectively. These values together with that for Et(2)S (-8.7 +/- 0.1 cm(3) mol(-1)) determined previously shows that variation of electronic properties, steric factors being kept constant, change the reactivity markedly, but have no observable influence on the activation volumes. Stability constants beta(1) for five palladium thioether complexes derived as the ratio between rate constants for forward and reverse reactions vary between (1.2 +/- 0.3) x 10(4) and (3.2 +/- 0. 7) x 10(4) M(-1).

Complexation of Constrained Ligands Piperazine, N-substituted Piperazines, and Thiomorpholine

Complexation of the symmetric cyclic diamine piperazine (1,4-diazacyclohexane) has been examined in dry dimethyl formamide by spectrophotometric titrations (with Cu2+, Ni2+) to define formation constants, and by stopped-flow kinetics to define the complexation rates and reaction pathway. Initial formation of a rarely observed eta(1)-piperazine intermediate occurs in a rapid second-order reactions. This intermediate then undergoes two competing reactions: formation of (chelated) eta(2)-piperazine (ML) or the formation of (bridging) mu-piperazine (in M2L and M2L3, speciation depending on relative concentrations). Protonation constants and formation constants for complexation in water of N-ethylpiperazine and thiomorpholine (1-aza-4-thiocyclohexane, tm) have been determined by potentiometric titration; 1:1 complexes with first-row M2+ display a log K from similar to 4 to 6, with speciation that suggests chelation of the heterocycles may be involved. Complexation of thiomorpholine has been further probed by the synthesis of Pd-II complexes. The N-monodentate coordination mode has been confirmed in trans-[Pd(tm)(2)Br-2] by an X-ray crystal structure. Complexation of N-(2-aminoethyl)piperazine to Cu-II as a bidentate ligand involving the primary and tertiary amines is also defined by an X-ray crystal structure.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. 88-05-1, you can contact me at any time and look forward to more communication.

Synthetic studies of neoclerodane diterpenes from Salvia divinorum: role of the furan in affinity for opioid receptors

Further synthetic modi. cation of the furan ring of salvinorin A (1), the major active component of Salvia divinorum, has resulted in novel neoclerodane diterpenes with opioid receptor affinity and activity. A computational study has predicted 1 to be a reproductive toxicant in mammals and is suggestive that use of 1 may be associated with adverse effects. We report in this study that piperidine 21 and thiomorpholine 23 have been identified as selective partial agonists at kappa opioid receptors. This indicates that additional structural modi. cations of 1 may provide ligands with good selectivity for opioid receptors but with reduced potential for toxicity.

Investigations of primary and secondary amine carbamate stability by H-1 NMR spectroscopy for post combustion capture of carbon dioxide

Carbamate formation is one of the major chemical reactions that can occur in solution in the capture of CO2 by amine-based solvents, and carbamate formation makes a significant enthalpy contribution to the absorption-desorption of CO2 that occurs in the absorber/stripper columns of the PCC process. Consequently, the formation of carbamates of selected series of primary and secondary amines over the temperature range (288 to 318) K has been investigated by equilibrium H-1 NMR studies, and the stability constants (K-9) for the equilibrium: RNH2 + HCO3- reversible arrow(K9) RNHCOO- + H2O are reported. van’t Hoff analyses have resulted in standard molar enthalpies, Delta H-m(o), and entropies, Delta S-m(o), of carbamate formation. A Delta H-m(o) – Delta S-m(o) plot generates a linear correlation for carbamate formation (providing a mean standard molar free energy, Delta G(m)(o), for carbamate formation of about -7 kJ . mol (1)), and this relationship helps provide a guide to the selection of an amine(s) solvent for CO2 capture, in terms of enthalpy considerations. A linear Delta H-m(o) – Delta S-m(o) plot also occurs for carbamate protonation. The formation of the carbamates has been correlated with systematic changes in composition and structure, and steric effects have been identified by comparing molecular geometries obtained using density functional B3LYP/6-311++G(d,p) calculations. Trends in steric effects have been identified in the series of compounds monoethanolamine (MEA), 1-amino-2-propanol, 2-amino-1-propanol (AP) and 2-amino-2-methyl-1-propanol (AMP). In the case of 2-piperidinemethanol, 2-piperidineethanol and 3-piperidinemethanol, strong intramolecular hydrogen bonding is shown to be the likely cause for lack of carbamate formation, and in the ring systems of pyrrolidine, morpholine, piperidine and thiomorpholine trends in carbamate formation (as given by K-9) have been correlated with the internal ring angle at the amine nitrogen, as well as the planarity of the environment around the nitrogen atom.
