The oral S1PR1 agonist ponesimod demonstrated substantial efficacy in a phase II clin. trial of psoriasis. Unfortunately, systemic side effects were observed, which included lymphopenia and transient bradycardia. We sought to develop a topical soft-drug S1PR1 agonist with an improved therapeutic index. By modifying ponesimod, we discovered an ester series of S1PR agonists. To increase metabolic instability in plasma we synthesized esters described as specific substrates for paraoxonase and butyrylcholinesterases, esterases present in human plasma.

Bijleveld, Johan C. published the artcileControlling morphology and photovoltaic properties by chemical structure in copolymers of cyclopentadithiophene and thiophene segments, Category: alcohols-buliding-blocks, the publication is Solar Energy Materials & Solar Cells (2010), 94(12), 2218-2222, database is CAplus.

A series of polythiophenes (PTn) based on dialkyl-cyclopentadithiophene (CPDT) units alternating with short un-substituted thiophene segments of length n (n being the number of thiophenes) along the chain has been synthesized to control the morphol. of PTn:PCBM blends for solar cell applications via the chem. structure of the polymer rather than via (post) processing conditions. The degree of phase separation in PTn:PCBM blends can be controlled via n, because with increase in n the number of solubilizing side chains per thiophene is reduced. For the most soluble derivative, PT0, we find that PCBM crystallizes first, while for the least soluble version, PT3, polymer aggregation prevails. The most intimately mixed morphol. and best solar cells were obtained for PT2, which exhibits a power conversion efficiency (PCE) of about 1.5% under AM1.5G conditions when mixed with PCBM. Although the final PCE is moderate, the study represents an example of a rational approach towards morphol. control via chem. structure, rather than via processing.

Rozsar, Daniel published the artcileBifunctional Iminophosphorane Catalyzed Enantioselective Sulfa-Michael Addition to Unactivated α,β-Unsaturated Amides, Application of 2-Phenylethanethiol, the publication is Journal of the American Chemical Society (2022), 144(2), 1006-1015, database is CAplus and MEDLINE.

The first metal-free catalytic intermol. enantioselective Michael addition to unactivated α,β-unsaturated amides was described. Consistently high enantiomeric excesses and yields were obtained over a wide range of alkyl thiol pronucleophiles and electrophiles under mild reaction conditions, enabled by a novel squaramide-based bifunctional iminophosphorane (BIMP) catalyst. Low catalyst loadings (2.0 mol %) were achieved on a decagram scale, demonstrating the scalability of the reaction. Computational anal. revealed the origin of the high enantiofacial selectivity via anal. of relevant transition structures and provided substantial support for specific noncovalent activation of the carbonyl group of the α,β-unsaturated amide by the catalyst.

Hammerl, Richard published the artcileQuantitative Proton NMR Spectroscopy for Basic Taste Recombinant Reconstitution Using the Taste Recombinant Database, Recommanded Product: 2-Hydroxy-2-phenylacetic acid, the publication is Journal of Agricultural and Food Chemistry (2021), 69(48), 14713-14721, database is CAplus and MEDLINE.

The quant. determination of putative taste active metabolites, the ranking of these compounds in their sensory impact based on dose-overthreshold (DoT) factors, followed by confirmation of their relevance by reconstitution and omission experiments enables the decoding of the non-volatile sensometabolome of certain foods. The identification and quantitation of target taste compounds by liquid chromatog.-tandem mass spectrometry (LC-MS/MS), high-performance liquid chromatog.-UV/visible (HPLC-UV/Vis) spectroscopy, or high-performance ion chromatog. (HPIC) is often laborious and time-consuming. In this work, we present a novel quant. ¹H NMR approach for reconstituting basic taste recombinants of different foods, including apple juice, balsamic vinegar, golden chanterelles, process flavor, and shrimp. Compound identification using the taste recombinant database, followed by absolute quantitation via quant. ¹H NMR (qHNMR), enables a fast and direct reconstitution of basic taste recombinants. The taste profile anal. of basic taste recombinants was generated via qHNMR in less than 15 min and compared with literature data acquired by LC-MS/MS and/or HPLC-UV/Vis and revealed identical results for all taste qualities. A determination of limit of detection (LoD) values for S/N = 50 of various proton signals with different integrals and multiplicities demonstrated that taste recognition thresholds of all basic tastants are far above those of LoD concentrations under the chosen conditions. Therefore, our exptl. setup is able to detect basic taste-active compounds well below their taste recognition thresholds.

Marcinkowska, Monika published the artcileKey Odorants of Raw and Cooked Green Kohlrabi (Brassica oleracea var. gongylodes L.), Computed Properties of 4410-99-5, the publication is Journal of Agricultural and Food Chemistry (2021), 69(41), 12270-12277, database is CAplus and MEDLINE.

Volatile compounds of raw and cooked green kohlrabi were investigated using a sensomics approach. A total of 55 odor-active compounds were detected and identified in raw and cooked green kohlrabi using GC-O. Twenty-eight odor-active compounds with high flavor dilution (FD) factors ranging from 64 to 1024 were quantitated, and odor activity values (OAVs) were determined Eight compounds showed high OAVs in raw and cooked kohlrabi: five sulfur compounds (di-Me trisulfide, Me 2-methyl-3-furyl disulfide, and three isothiocyanates (1-isothiocyanato-3-(methylsulfanyl)propane, benzyl isothiocyanate, and 1-isothiocyanato-4-(methylsulfanyl)butane)), two lipid oxidation products (1-octen-3-one and trans-4,5-epoxy-(2E)-dec-2-enal), and 2-isopropyl-3-methoxypyrazine. Among these, the sulfur compounds contributed most to the overall smell of the raw and cooked vegetables. The quantitation anal. indicates that the eight odorants are the backbone compounds for raw and cooked kohlrabi. The OAVs for the backbone compounds and also for minor odorants are clearly higher in raw kohlrabi than in the cooked one. Differences can be explained by the influence of the cooking process.

Lynch, John K. published the artcileOptimization of Chromone-2-carboxamide Melanin Concentrating Hormone Receptor 1 Antagonists: Assessment of Potency, Efficacy, and Cardiovascular Safety, Computed Properties of 328-90-5, the publication is Journal of Medicinal Chemistry (2006), 49(22), 6569-6584, database is CAplus and MEDLINE.

Evaluation of multiple structurally distinct series of melanin concentrating hormone receptor 1 antagonists in an anesthetized rat cardiovascular assay led to the identification of a chromone-2-carboxamide series as having excellent safety against the chosen cardiovascular endpoints at high drug concentrations in the plasma and brain. Optimization of this series led to considerable improvements in affinity, functional potency, and pharmacokinetic profile. This led to the identification of a 7-fluorochromone-2-carboxamide (I) that was orally efficacious in a diet-induced obese mouse model, retained a favorable cardiovascular profile in rat, and demonstrated dramatic improvement in effects on mean arterial pressure in our dog cardiovascular model compared to other series reported by our group. However, this analog also led to prolongation of the QT interval in the dog that was linked to affinity for hERG channel and unexpectedly potent functional blockade of this ion channel.

Ryan, Timothy M. published the artcileSmall Amphipathic Molecules Modulate Secondary Structure and Amyloid Fibril-forming Kinetics of Alzheimer Disease Peptide Aβ_1-42, Application of (2R,3S,4S,5R,6S)-2-(Hydroxymethyl)-6-(octylthio)tetrahydro-2H-pyran-3,4,5-triol, the publication is Journal of Biological Chemistry (2012), 287(20), 16947-16954, database is CAplus and MEDLINE.

Amyloid fibril formation is associated with a number of debilitating systemic and neurodegenerative diseases. One of the most prominent is Alzheimer disease in which aggregation and deposition of the Aβ peptide occur. Aβ is widely considered to mediate the extensive neuronal loss observed in this disease through the formation of soluble oligomeric species, with the final fibrillar end product of the aggregation process being relatively inert. Factors that influence the aggregation of these amyloid-forming proteins are therefore very important. The authors have screened a library of 96 amphipathic mols. for effects on Aβ_1-42 aggregation and self-association The authors find, using thioflavin T fluorescence and electron microscopy assays, that 30 of the mols. inhibit the aggregation process, whereas 36 activate fibril formation. Several activators and inhibitors were subjected to further anal. using anal. ultracentrifugation and CD. Activators typically display a 1:10 peptide:detergent stoichiometry for maximal activation, whereas the inhibitors are effective at a 1:1 stoichiometry. Anal. ultracentrifugation and CD experiments show that activators promote a mixture of unfolded and β-sheet structures and rapidly form large aggregates, whereas inhibitors induce α-helical structures that form stable dimeric/trimeric oligomers. The results suggest that Aβ_1-42 contains at least one small mol. binding site, which modulates the secondary structure and aggregation processes. Further studies of the binding of these compounds to Aβ may provide insight for developing therapeutic strategies aimed at stabilizing Aβ in a favorable conformation.

Jin, Yongdong published the artcileBacteriorhodopsin-monolayer-based planar metal-insulator-metal junctions via biomimetic vesicle fusion: preparation, characterization, and bio-optoelectronic characteristics, Related Products of alcohols-buliding-blocks, the publication is Advanced Functional Materials (2007), 17(8), 1417-1428, database is CAplus.

A reliable and reproducible method for preparing bacteriorhodopsin (bR)-containing metal-biomol.-monolayer-metal planar junctions via vesicle fusion tactics and soft deposition of Au top electrodes is reported. Optimum monolayer and junction preparations, including contact effects, are discussed. The electron-transport characteristics of bR-containing membranes are studied systematically by incorporating native bR or artificial bR pigments derived from synthetic retinal analogs, into single solid-supported lipid bilayers. Current-voltage (I-V) measurements at ambient conditions show that a single layer of such bR-containing artificial lipid bilayers pass current in solid electrode/bilayer/solid electrode structures. The current is passed only if retinal or its analog is present in the protein. Furthermore, the preparations show photoconductivity as long as the retinal can isomerize following light absorption. Optical characterization suggests that the junction photocurrents might be associated with a photochem. induced M-like intermediate of bR. I-V measurements along with theor. estimates reveal that electron transfer through the protein is over four orders of magnitude more efficient than what would be estimated for direct tunneling through 5 nm of water-free peptides. The authors’ results furthermore suggest that the light-driven proton-pumping activity of the sandwiched solid-state bR monolayer contributes negligibly to the steady-state light currents that are observed, and that the orientation of bR does not significantly affect the observed I-V characteristics.
