The formation of fluorescent alkali metal and alkaline earth complexes by 1-(2-{10-[2-piperazinoethyl]-9-anthryl}ethyl)piperazine and alkaline earth complexes by 4-(2-{10-[2-(1,4-thiazinan-4-yl)ethyl]-9-anthryl}ethyl)thiomorpholine in acetonitrile

The formation of fluorescent alkali metal and alkaline earth complexes of 1-(2-{10-[2-piperazinoethyl]9- anthryl} ethyl) piperazine ( 1) and alkaline earth complexes by 4-(2-{10-[2-(1,4-thiazinan-4-yl) ethyl]-9-anthryl} ethyl) thiomorpholine ( 2) in acetonitrile is reported. Both ( 1) and ( 2) have ‘fluorophore – spacer – receptor’ structures in the sequences ‘anthracene – dimethylene – piperazine’ and ‘anthracene – dimethylene – thiomorpholine’, respectively. Complexation by alkali metal ions and alkaline earth ions, Mm+, modulate photoinduced electron transfer ( PET) to increase the fluorescence of ( 1) and complexation of alkaline earth ions similarly increases the fluorescence of ( 2). The two receptors of ( 1) and ( 2) may either complex Mm+ singly to form [ML](m+) or cooperatively to form a ‘sandwich’ complex [ML’](m+) characterized together by complexation constant K-1 and quantum yield phi(1). They may also complex two Mm+ in [M2L](2m+) characterized by K-2 and phi(2). Typical data are exemplified for (1) and Mm+ = Na+ by K-1 = 1.33 x 10(5) dm(3) mol(-1) (phi(1) = 0.02) and K-2 = 4.20 x 10(2) dm(3) mol(-1) (phi(1) = 0.07), for (1) and Mm+ = Ca2+ by K-1 = 3.2 x 10(6) dm(3) mol(-1) (phi(1) = 0.34) and K-2 = 1.32 x 10(4) dm(3) mol(-1) (phi(2) = 0.54), and for (2) and Mm+ = Ca2+ by K-1 = 2.29 x 10(4) dm(3) mol(-1) (phi(1) = 0.20) and K-2 = 8.0 x 10(2) dm(3) mol(-1) (phi(2) = 0.57) at 298.2 K and I = 0.05 mol dm(-3) (NEt4ClO4). These data are compared with those for the alkaline earth complexes of 4-{2-[10-(2-morpholinoethyl)-9-anthryl] ethyl} morpholine. In 40 : 60 (v/v) 1,4-dioxan/water, protonation modulates PET to increase the fluorescence of (1) H-4(4+) and ( 2) H-2(2+). (The pK(a) values of (1) H-4(4+) are 9.02, 8.06, 4.32, and 2.96 at 298.2 K and I = 0.05 mol dm(-3) (NEt4ClO4).) The syntheses of (1) and (2) are reported.

Synthesis, in vitro, and in vivo (Zebra fish) antitubercular activity of 7,8-dihydroquinolin-5(6H)-ylidenehydrazinecarbothioamides

We, herein, describe the synthesis of a series of novel aryl tethered 7,8-dihydroquinolin-5(6H)-ylidenehydrazinecarbothioamides 4a-v, which showed in vitro and in vivo antimycobacterial activity against Mycobacterium tuberculosis (Mtb) H37Rv. The intermediates dihydro-6H-quinolin-5-ones 3a-v were synthesized from beta-enaminones, reacting with cyclochexane-1,3-dione/5,5-dimethylcyclohexane-1,3-dione and ammonium acetate using a modified Bohlmann-Rahtz reaction conditions. They were further reacted with thiosemicarbazide to give the respective hydrazine carbothioamides 4a-v. All the new analogues 4a-v, were characterized by their NMR and mass spectral data analysis. Among the twenty-two compounds screened for in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv (ATCC27294), two compounds, 4e and 4j, exhibited the highest inhibition with an MIC of 0.39 mu g/mL. Compounds 4a, 4g, and 4k were found to inhibit Mtb at an MIC of 0.78 mu g/mL. Hydrazinecarbothioamides 4a-k, exhibited enhanced activity than dihydroquinolinones 3a-k. The observed increase in potency provides a clear evidence that hydrazinecarbothioamide is a potential pharmacophore, collectively imparting synergistic effect in enhancing antitubercular activity of the dihydroquinolinone core. The in vivo (Zebra fish) antimycobacterial screening of the in vitro active molecules led to the identification of a hit compound, 4j, with significant activity in the Mtb nutrient starvation model (2.2-fold reduction). Docking studies of 4j showed a hydrogen bond with the P156 residue of the protein.

In situ H-1 NMR study of cytochrome P450 inhibition by metyrapol in mycobacterium aurum MO1

In situ H-1 NMR was used to monitor incubations of Mycobacterium aurum MO1 with thiomorpholine or morpholine in the presence of metyrapone, a specific inhibitor of P450. Unexpected signals were detected and assigned to metyrapol, the reduction product of metyrapone. The inhibitory effects of racemic metyrapol and of its (-)-enantiomer were compared to that of metyrapone. They are similar.

Application of a new chiral derivatizing agent to the enantioseparation of secondary amino acids

A new chiral derivatizing, agent, (S)-N-(4-nitrophenoxycarbonyl)phenylalanine methoxyethyl ester, (S)-NIFE, was applied for the high-performance liquid chromatographic separation of enantiomers of 19 unnatural secondary amino acids: proline, pipecolic acid analogues, piperazine-2-carboxylic acid, morpholine-3-carboxylic acid, thiomorpholine-3-carboxylic acid and analogues containing the 1,2,3,4-tetrahydroisoquinoline, 1,2,3,4-tetrahydronorharmane, 1,2,3,4-tetrahydro-2-carboline and 2-benzazepine skeletons. Excellent resolutions were achieved for most of the investigated compounds by using a reversed-phase mobile phase system. The conditions of separation were optimized by variation of the mobile phase composition. (C) 2002 Elsevier Science B.V. All rights reserved.

The Vinylic S-N Reactions of Nitrodienes with Heteroatom-Substituted Nuchleophilies and Their Structural Studies

Herein, we report the reactions of 1,1,2,4,4-pentachloro-3-nitro-1,3-butadiene 1a and (1Z)-1-bromo-1,2,4,4-tetrachloro-3-nitro-1,3-butadiene 1b with nitrogen- and sulfur-containing nucleophiles to obtain highly functionalized S-, S,S-, S,S,S-, S,O- and N,S-substituted-polyhalodiene-3-nitro-1,3-butadiene derivatives.

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.

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.

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.

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. Interested yet? Read on for other articles about 64-10-8, you can contact me at any time and look forward to more communication. Reference of 64-10-8.

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.

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.
