Synthesis, stereochemical, single crystal X-ray structural and antimicrobial studies of some isobutyl-1,2,6-triaryl-4-(arylamino)-1,2,5,6-tetrahydropyridine-3-carboxylates: Exploring RAHB with S(6) graph set

A new set of compounds which are intra-molecularly hydrogen bonded have been synthesized and analyzed with special reference to Resonance Assisted Hydrogen Bonding (RAHB). The structure and stereochemistry of the synthesized compounds (1-10), were established on the basis of their analytical and spectral data (IR, H-1, C-13 NMR, HOMOCOSY, NOESY, HSQC and HMBC). The structure in the solid state for 5, 9 and 10 is clearly established by single crystal X-ray diffraction analysis. Spectral and single crystal Xray structural study confirms the flattened boat conformation of the heterocyclic ring which is analyzed with the help of dihedral angles and the mean plane deviations. Hirshfeld surface analysis is carried out and the packing interactions are discussed. The prevalent intramolecular hydrogen bonding is well proved by XRD analysis and the type of hydrogen bonding is classified as S(6), and the resonance assistance for the hydrogen bonding is also quantified and discussed explicitly. Antimicrobial studies were performed for the synthesized compounds against some Gram positive and Gram negative bacterial strains and some fungal strains and the results are summarized.

Excess molar volumes and excess isentropic compressibilities of liquid mixtures formed by tetrahydropyran, piperidine and cyclic ketones at temperature from 293.15 to 308.15 K.

The densities, rho, rho(123) and speeds of sound, u, u(123) of binary Tetrahydropyran (1) Piperidine (2) and ternary Tetrahydropyran (1) Piperidine (2) + Cyclohexanone or Cycloheptanone (3) mixtures have been measured over the whole range of mole fraction at 293.15, 298.15, 303.15, 308.15 K and atmospheric pressure. The observed data have been utilized to determine excess molar volumes, (V-E)(12), V-123(E) and excess isentropic compressibilities, (kappa(E)(S))(12,) (kappa(E)(S))(123) for the binary and ternary liquid mixtures respectively. The (V-E)(12), V-123(E) and (kappa(E)(S))(12,) (kappa(E)(S))(123) data have been fitted to Redlich-Kister equation to determine binary as well as ternary adjustable parameters along with standard deviations. The Moelywn-Huggins concept of interaction between the surfaces of the binary mixture constituents has been extended (Graph theory) to evaluate excess molar volumes and excess isentropic compressibilities of ternary mixtures using the concept of connectivity parameter of third degree of molecules, (3)xi (which deals with the topology of the constituents in pure and mixed state) to obtain an expression that describe well the measured data.

Synthesis and Characterization of Nickel(II) Salphen Complex with Piperidine Side Chain and Interaction Study with Dengue DNA

Development of DNA biosensor model based on interaction of metal complexes as DNA hybridization marker can be used for dengue viruses early diagnosis. Nickel(II) salphen complex with piperidine side chain were successfully synthesized and characterized using Nucleus Magnetic Resonance Spectroscopy (NMR), mass spectrometry, differential scanning calorimetry and FTIR. The binding mode and interactions of nickel(II) salphen complex with piperidine side chain and dengue DNA were determined by uv-vis titration. Based on ultra violet visible spectra, hypochromism and redshift (bathochromism) were observed after upon tiration of the complex with dengue DNA which suggested formation of new complex. Nickel(II) salphen complex with piperidine side chain interact with dengue DNA by intercalation binding mode with the binding constant, Kb= 4.576×10(5) M-1.

Spirocyclic Nitroxides as Versatile Tools in Modern Natural Sciences: From Synthesis to Applications. Part I. Old and New Synthetic Approaches to Spirocyclic Nitroxyl Radicals

Spirocyclic nitroxyl radicals (SNRs) are stable paramagnetics bearing spiro-junction at alpha-, beta-, or gamma-carbon atom of the nitroxide fragment, which is part of the heterocyclic system. Despite the fact that the first representatives of SNRs were obtained about 50 years ago, the methodology of their synthesis and their usage in chemistry and biochemical applications have begun to develop rapidly only in the last two decades. Due to the presence of spiro-function in the SNRs molecules, the latter have increased stability to various reducing agents (including biogenic ones), while the structures of the biradicals (SNBRs) comprises a rigid spiro-fused core that fixes mutual position and orientation of nitroxide moieties that favors their use in dynamic nuclear polarization (DNP) experiments. This first review on SNRs will give a glance at various strategies for the synthesis of spiro-substituted, mono-, and bis-nitroxides on the base of six-membered (piperidine, 1,2,3,4-tetrahydroquinoline, 9,9 ‘(10H,10H ‘)-spirobiacridine, piperazine, and morpholine) or five-membered (2,5-dihydro-1H-pyrrole, pyrrolidine, 2,5-dihydro-1H-imidazole, 4,5-dihydro-1H-imidazole, imidazolidine, and oxazolidine) heterocyclic cores.

In Vivo Imaging of the Intra- and Extracellular Redox Status in Rat Stomach with Indomethacin-Induced Gastric Ulcers Using Overhauser-Enhanced Magnetic Resonance Imaging

Aims: Repeated use of nonsteroidal anti-inflammatory drugs can induce changes in the redox status, including production of reactive oxygen species (ROS), but the specific details of these changes remain unknown. Overhauser-enhanced magnetic resonance imaging (OMRI) has been used in vivo to monitor the redox status in several diseases and map tissue oxygen concentrations. We monitored the intra- and extracellular redox status in the stomach of rats with indomethacin-induced gastric ulcers using OMRI and investigated the relationship with gastric mucosal damage. Results: One hour after oral administration of indomethacin (30 mg/kg), OMRI measurements in the stomach were made following nitroxyl probe administration. OMRI with the membrane-permeable nitroxyl probe, 4-hydroxy-2,2,6,6-tetramethyl-piperidine-1-oxyl (TEMPOL), demonstrated a redox change toward oxidation, which was reversed by a membrane-permeable antioxidant. Conversely, imaging with the impermeable probe, 4-trimethylammonium-2,2,6,6-tetramethyl-piperidine-1-oxyl (CAT-1), demonstrated little redox change. Redox imbalance imaging of a live rat stomach with indomethacin-induced gastric ulcers was produced by dual imaging of N-15-labeled TEMPOL and N-14-labeled CAT-1, in addition to imaging with another membrane-permeable N-15-labeled probe, 3-methoxycarbonyl-2,2,5,5-tetramethyl-pyrrolidine-1-oxyl (MC-PROXYL), and N-14-labeled CAT-1. Pretreatment with MC-PROXYL suppressed gastric mucosal damage, whereas pretreatment with CAT-1 did not suppress ulcer formation. Innovation: OMRI combined with a dual probe is a less invasive imaging technique for evaluation of intracellular ROS production contributing to the formation of gastric ulcers in the stomach of indomethacin-treated rats, which cannot be done with other methods. Conclusion: This method may be a very powerful tool for characterizing the pathogenesis of various diseases and may have medical applications.

Practical Early Development Synthesis of Nav1.7 Inhibitor GDC-0310

The concise early development route to the Nav1.7 inhibitor GDC-0310 is described. The active pharmaceutical ingredient (API) contains one stereocenter, which was obtained with high enantiomeric excess (>99:1) by using an S(N)2 displacement approach to connect two intermediates: a chiral benzyl alcohol and a piperidine. The synthesis of the piperidine building block proceeded via a regioselective SNAr reaction on 1-chloro-2,4-difluorobenzene byN-Boc-4-piperidinemethanol, followed by installation of the methyl ester group by electrophilic aromatic bromination and a palladium-catalyzed alkoxycarbonylation. A subsequent Suzuki-Miyaura cross-coupling reaction was then telescoped directly into cleavage of the Boc group to provide the advanced piperidine intermediate. The key feature of the synthesis is the highly selective S(N)2 displacement of the chiral mesylate of (R)-1-(3,5-dichlorophenyl)ethan-1-ol with the piperidine intermediate, followed by a chiral purity upgrade via the corresponding (1S)-(+)-camphorsulfonic acid salt. After standard hydrolysis of the methyl ester and CDI mediated amidation to couple the resulting acid with methanesulfonamide, enantiomerically pure GDC-0310 was obtained in high overall yield (37%) on a 6.5 kilogram scale.

Pick a Wick: A Simple, Ultrafast Combustion Synthesis of Co3O4 Dispersed Carbon for Enhanced Oxygen Evolution Kinetics

Mass transport and charge transfer at an interface play a crucial role in governing the electrochemical performance of a material. Wider meso-/macropores are expected to enhance the reaction kinetics by facilitating the ion transport to and fro from an active interface, thereby continuously regenerating it at accelerated rates. Herein, we report a generic, simple, and ultrafast synthetic method to obtain highly graphitized porous carbon containing well-dispersed Co3O4 nanoparticles (similar to 1 wt % Co) using cobalt acetate and piperidine precursors. The obtained catalyst (Co3O4@CS) exhibits onset potential and oxygen evolution kinetics similar to that of the state-of-the-art catalyst, RuO2. For oxygen evolution reaction (OER), the synthesized material exhibits excellent cycling performance over 2000 cycles. Such a performance metric can be attributed to the uniform dispersion of active sites (Co3O4) over a low-density, highly interconnected conducting carbon matrix leading to facile mass transport and charge transfer, respectively.
