Structure-directed formation of the dative/covalent bonds in complexes with C70MIDLINE HORIZONTAL ELLIPSISpiperidine

The combined experimental-computational study has been performed to investigate the complexes formed between C-70 carbon allotrope and piperidine. The results of FT-IR, H-NMR, and C-NMR measurements, together with the calculations based on the DFT approach and molecular dynamics simulations, prove the existence of dative/covalent bonding in C70MIDLINE HORIZONTAL ELLIPSISpiperidine complexes. The dative bond forms not only at the region of five- and six-membered rings, observed previously with C-60, but also at the region formed of six-membered rings. The structure, i.e., nonplanarity, explains the observed dative bond formation. New findings on the character of interaction of secondary amines with C-70 bring new aspects for the rational design of modified fullerenes and their applications in electrocatalysis, spintronics, and energy storage.

Alkaloid-Rich Crude Extracts, Fractions and Piperamide Alkaloids of Piper guineense Possess Promising Antibacterial Effects

Piper guineense is a food and medicinal plant commonly used to treat infectious diseases in West-African traditional medicine. In a bid to identify new antibacterial compounds due to bacterial resistance to antibiotics, twelve extracts of P. guineense fruits and leaves, obtained by sequential extraction, as well as the piperine and piperlongumine commercial compounds were evaluated for antibacterial activity against human pathogenic bacteria. HPLC-DAD and UHPLC/Q-TOF MS analysis were conducted to characterize and identify the compounds present in the extracts with promising antibacterial activity. The extracts, with the exception of the hot water decoctions and macerations, contained piperamide alkaloids as their main constituents. Piperine, dihydropiperine, piperylin, dihydropiperylin or piperlonguminine, dihydropiperlonguminine, wisanine, dihydrowisanine and derivatives of piperine and piperidine were identified in a hexane extract of the leaf. In addition, some new piperamide alkaloids were identified, such as a piperine and a piperidine alkaloid derivative and two unknown piperamide alkaloids. To the best of our knowledge, there are no piperamides reported in the literature with similar UV absorption maxima and masses. A piperamide alkaloid-rich hexane leaf extract recorded the lowest MIC of 19 mu g/mL against Sarcina sp. and gave promising growth inhibitory effects against S. aureus and E. aerogenes as well, inhibiting the growth of both bacteria with a MIC of 78 mu g/mL. Moreover, this is the first report of the antibacterial activity of P. guineense extracts against Sarcina sp. and E. aerogenes. Marked growth inhibition was also obtained for chloroform extracts of the leaves and fruits against P. aeruginosa with a MIC value of 78 mu g/mL. Piperine and piperlongumine were active against E. aerogenes, S. aureus, E. coli, S. enterica, P. mirabilis and B. cereus with MIC values ranging from 39-1250 mu g/mL. Notably, the water extracts, which were almost devoid of piperamide alkaloids, were not active against the bacterial strains. Our results demonstrate that P. guineense contains antibacterial alkaloids that could be relevant for the discovery of new natural antibiotics.

Ring opening of 2,6-diaryl-3,5-diphenyl piperidine-4-one by acetic acid: Structural studies and Hirshfeld surface analysis of (E)-4-aryl-1,3-diphenylbut-3-en-2-ones

Six alpha,beta-unsaturated carbonyl compounds have been obtained from 2,6-diaryl-3,5-diphenylpiperidine-4-one by the treatment with acetic acid. A plausible mechanism for the ring opening of 2,6-diaryl-3,5-diphenyl piperidin-4-ones is proposed. The resultant (E)-4-aryl-1,3-diphenylbut-3-en-2-ones have been characterized by H-1 and C-13 nuclear magnetic resonance (NMR) spectral studies. One of the compounds was completely characterized by 2D NMR techniques, and structure of the compound is further proved by single-crystal X-ray diffraction (XRD) analysis. The crystal structure, three-dimensional framework of crystal, and Hirshfeld surface analysis of two of the compounds have been discussed. In the crystals, molecules are mainly linked by C-H center dot center dot center dot O hydrogen bonding interactions, and this interaction forms an inversion dimer with R-2(1)(6) and R-2(1)(10) ring motifs in one of the compounds. Hirshfeld surface indicates the dominance of H center dot center dot center dot H contacts on the overall surface.

Sterically encumbered dianionic dicarboranyl pincer ligand (C5H3N)(C2B10H11)(2) and its CNC Nickel(II) complex

The novel 2,6-bis(carborane) pyridine (C5H3N)(C2B10H11)(2) ligand precursor containing two icosahedral carborane clusters attached to the pyridine ring was synthesized by the SNAr reaction between 2,6-difluoropyridine and lithiated ortho-carborane LiC2B10H11. Lithiation of the proligand at carbon atoms of carborane cages and the subsequent reaction with Ni(PPh3)(2)Cl-2 afforded the square-planar Ni(II) pincer complex {(C5H3N)(C2B10H10)(2)} Ni(CH3CN). X-ray single crystal diffraction revealed extreme steric hindrance around the metal center in the complex imposed by two carboranyl groups in the rigid pincertype framework, which was also manifested by the high value of the ligand buried volume % V-bur = 70.6%. The title pincer complex {(C5H3N)(C2B10H10)(2)} Ni(CH3CN) was found to be a competent catalyst for nucleophilic addition of piperidine to acetonitrile. (C) 2017 Elsevier B.V. All rights reserved.

One pot synthesis, physicochemical and photophysical investigation of biologically active pyridine-3-carboxylate (ECPC) as probe to determine CMC of surfactants in organized media

Ethyl 4 – (9-ethyl-9H-carbazol-3-yl) – 2 – methyl – 5- oxo – 4, 5 – dihydro-1H-indeno[1,2-b]pyridine-3-carboxylate (ECPC) was prepared by one pot multi component reaction of 9-ethyl-9H-carbazole-3-carbaldehyde, indane-1,3-dione, ethyl acetoacetate and ammonium acetate in the presence few drops of piperidine. Structure of the title compound (ECPC) was confirmed by the spectroscopic techniques (FT-IR, H-1-NMR, C-13-NMR, EI-MS) and elemental analysis. Photophysical parameter of the ECPC such as transition dipole moment, extinction coefficient, stokes shift, oscillator strength, fluorescence quantum yield were calculated by using the different solvents (based on the polarity). The results of compound ECPC showed red shift in absorbance and emission spectrum with increase in the polarity of the solvents from n-heptane to DMSO. Emission spectrum of ECPC effected with anionic and cationic surfactant so ECPC can be used as probe to determine critical micelle concentrations (CMC) of anionic sodium dodecyl sulfate (SDS) and cationic cetyltrimethylammonium bromide (CTAB) surfactant. The in-vitro antibacterial activity of ECPC was examined by the disk diffusion and minimum inhibitory concentration (MIC) methods against two Gram-positive and two Gram-negative bacteria by using Tetracycline as reference drug.

A novel piperidine identified by stem cell-based screening attenuates pulmonary arterial hypertension by regulating BMP2 and PTGS2 levels

Genetic defects in bone morphogenetic protein type II receptor (BMPRII) signalling and inflammation contribute to the pathogenesis of pulmonary arterial hypertension (PAH). The receptor is activated by bone morphogenetic protein (BMP) ligands, which also enhance BMPR2 transcription. A small-molecule BMP upregulator with selectivity on vascular endothelium would be a desirable therapeutic intervention for PAH. We assayed compounds identified in the screening of BMP2 upregulators for their ability to increase the expression of inhibitor of DNA binding 1 (Id1), using a dual reporter driven specifically in human embryonic stem cell-derived endothelial cells. These assays identified a novel piperidine, BMP upregulator 1 (BUR1), that increased endothelial Idl expression with a half-maximal effective concentration of 0.098 mu mol.L-1. Microarray analyses and immunoblotting showed that BUR1 induced BMP2 and prostaglandin-endoperoxide synthase 2 (PTGS2) expression. BUR1 effectively rescued deficient angiogenesis in autologous BMPR2(+/R899X) endothelial cells generated by CRISPR/Cas9 and patient cells. BUR1 prevented and reversed PAH in monocrotaline rats, and restored BMPRII downstream signalling and modulated the arachidonic acid pathway in the pulmonary arterial endothelium in the Sugen 5416/hypoxia PAH mouse model. In conclusion, using stem cell technology we have provided a novel small-molecule compound which regulates BMP2 and PTGS2 levels that might be useful for the treatment of PAH.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 3040-44-6 is helpful to your research. Formula: C7H15NO.

Stereoselective synthesis of 2,6-disubstituted piperidine alkaloids

Among the large number of structurally diverse alkaloids, 2,6-disubstituted piperidine and its analogs have often been targeted when exploiting new synthetic techniques perhaps because of their strong pharmacological properties. This review outlines synthetic strategies to build the 2,6-disubstituted piperidine structural motif with a focus on stereochemical control of two substituents at C2 and C6. The key reactions in this process are then classified on the basis of how the piperidine rings were built with specific examples of natural products that control the stereochemical outcomes and their transition states.
