Liu, Yan published the artcileIdentification of a hormone response element that mediates suppression of APOF by LXR and PPARα agonists, Synthetic Route of 637-07-0, the publication is Biochimica et Biophysica Acta, Molecular and Cell Biology of Lipids (2020), 1865(3), 158583, database is CAplus and MEDLINE.

Here we show in human liver C3A cells that APOF mRNA levels are reduced by agonists of LXR and PPARα nuclear receptors. This neg. regulation requires co-incubation with the RXR agonist, retinoic acid. Bioinformatic anal. of the ∼2 kb sequence upstream of the APOF promoter identified one potential LXR and 4 potential PPARα binding sites clustered between nucleotides -2007 and -1961. ChIP anal. confirmed agonist-dependent binding of LXRα, PPARα, and RXRα to this hormone response element complex (HREc). A luciferase reporter containing the 2 kb 5′ APOF sequence was neg. regulated by LXR and PPARα ligands as seen in cells. This regulation was maintained in constructs lacking the ∼1700 nucleotides between the HREc and the APOF proximal promoter. Mutations of the HREc that disrupted LXRα and PPARα binding led to the loss of reporter construct inhibition by agonists of these nuclear receptors. siRNA knockdown studies showed that APOF gene regulation by LXRα or PPARα agonists did not require an interaction between these two nuclear receptors. Thus, APOF is subject to neg. regulation by agonist-activated LXR or PPARα nuclear receptors binding to a regulatory element ∼1900 bases 5′ to the APOF promoter. High fat, cholesterol-enriched diets likely reduce APOF gene expression via these receptors interacting at this regulatory site.

1-Ethynyl-2,3,4,5-tetramethylruthenocene was prepared by the reaction of 1-formyl-2,3,4,5-tetramethylruthenocene with trimethylsilyldiazomethyllithium and also by the reaction of 1-(2′,2′-dichlorovinyl)-2,3,4,5-tetramethylruthenocene, which was obtained from the reaction of 1-formyl-2,3,4,5-tetramethylruthenocene with Li di-Et dichloromethylphosphonate and t-BuLi in good yield. 1-Ethynyl-2,3,4,5-tetramethylruthenocene reacted with RuClP₂L (P₂ = 2 PPh₃ or dppe; L = η-C₅H₅, η-C₅Me₅, or η⁵-C₉H₇) in the presence of NH₄PF₆ or AgBF₄, followed by column chromatog. on deactivated Al₂O₃, to give Ru(CCRc’)P₂L in moderate or good yields. Ru(CCRc)P₂(η⁵-C₉H₇) and Ru(CCRc^*)P₂(η⁵-C₉H₇) were similarly prepared (Rc, Rc’, and Rc^* are ruthenocenyl, 2,3,4,5-tetramethylruthenocenyl, and 1′,2′,3′,4′,5′-pentamethylruthenocenyl, resp.). The structures of Ru(CCRc’)(dppe)(PPh₃)₂(η-C₅H₅), Ru(CCRc)(dppe)(η⁵-C₉H₇), and Ru(CCRc’)(dppe)(η⁵-C₉H₇) were determined by x-ray anal. Cyclic voltammetry of the acetylide complexes showed two well-separated quasi-reversible waves. Chem. oxidation of Ru(II) 2,3,4,5-tetramethylruthenocenylacetylide complexes gave products whose stability was dependent on the ligand on the Ru(II) moiety. The ¹³C NMR spectrum of the oxidized species isolated as stable crystals confirmed the structural rearrangement of the bridging acetylide ligand to a μ-η⁶:η¹-[(cyclopentadienylidene)ethylidene] ligand. The structure of [(η-C₅H₅)Ru(μ-η⁶:η¹-C₅Me₄:C:C)Ru(dppe)(η⁵-C₅Me₅)](BF₄)₂ was determined by x-ray anal.

Pijper, Thomas C. published the artcilePosition and Orientation Control of a Photo- and Electrochromic Dithienylethene Using a Tripodal Anchor on Gold Surfaces, Synthetic Route of 219537-97-0, the publication is Journal of Physical Chemistry C (2015), 119(7), 3648-3657, database is CAplus.

A tripodal system for anchoring photochromic dithienylethenes on gold surfaces is reported. The self-assembled monolayers of a tripod-functionalized dithienylethene were characterized by cyclic voltammetry, surface-enhanced Raman spectroscopy (SERS), and XPS. These data are compared with solution studies, solid state Raman spectroscopy, and d. functional theory (DFT) calculations We show that the tripod-functionalized dithienylethene forms stable monolayers on gold in which all three legs of the tripod are adsorbed via the thiol units, thus providing a fixed position and orientation of the dithienylethene moiety with respect to the surface. Importantly, immobilization in this way allows for retention of both the photochem. and electrochem. functionality of the dithienylethene unit and reduces photochem. fatigue observed in solution

Decamethoxine was the most active drug, as it inhibited 78% of the strains at 0.08-6.25 μg/mL concentration; at 12.5 μg/mL, the drug showed fungicidal activity against 20% of the strains. Levorin and amphotericin B displayed antifungal activity at 50 μg/mL concentration At 3.9-7.8, μg/mL enteroseptol inhibited 78% of the strains.

Shinohara, Naoki published the artcileSelective Modification of the N-Terminal Structure of Polytheonamide B Significantly Changes its Cytotoxicity and Activity as an Ion Channel, Safety of 3-Carboxy-N,N,N-trimethylpropan-1-aminium chloride, the publication is ChemMedChem (2012), 7(10), 1770-1773, S1770/1-S1770/7, database is CAplus and MEDLINE.

Polytheonamide B is an extremely cytotoxic natural product and is the largest nonribosomal peptide that has been described to date. Polytheonamide B is a linear chain polypeptide containing an N-terminal 5,5-dimethyl-2-oxohexanoate group (Ncap) and 48 amino acid residues of alternating D– and L-chirality; in addition, the secondary structure of this peptide was recently reported to be a remarkable β^6,3 helix with a length of approx. 45 Å. This helical tube structure is thought to function as a transmembrane ion channel in which the 4 Å hydrophobic pore provides a path for ion translocation. Planar bilayer experiments have previously demonstrated that the monomeric form of polytheonamide B functions as a monovalent cation-selective channel. The present work describes the synthesis of seven derivatives of polytheonamide B and examines the effect of N-terminal modification on cytotoxicity and ion channel activity.

Yoshii, Yoshihiro published the artcileFriedel-Crafts phenylsulfonylation of o-xylene, indan, and tetralin in nitrobenzene, Computed Properties of 61551-49-3, the publication is Nippon Kagaku Kaishi (1986), 1117-21, database is CAplus.

Friedel-Crafts reactions of o-xylene, indan, and tetralin with PhSO₂Cl in the presence of AlCl₃ in PhNO₂ were studied in relation to temperature effects on isomer distribution under kinetic conditions. In indan, the isomer ratio (3 to 4) increased with temperature, while the ratio (3 to 4) decreased in o-xylene and in tetralin. Differences of activation energies and activation entropies in the 3- and 4-position for o-xylene, indan, and tetralin were -0.39 kcal/mol, -2.0 e.u./mol; 0.16, -0.2; and -0.31, -1.5. Isokinetic temperature were -81 and -62° for o-xylene and tetralin, resp. These results suggest that the 3-position of o-xylene or tetralin is more reactive than the 4-position, whereas the 4-position is more reactive in indan. The reaction proceeded with a concerted mechanism in which strong acid-catalytic effect by AlCl₃ and base-catalyzed deprotonation by solvent and/or AlCl₄^– on the 3-position were observed in o-xylene and tetralin.
