Raimundo, Brian C. published the artcileIntegrating Fragment Assembly and Biophysical Methods in the Chemical Advancement of Small-Molecule Antagonists of IL-2: An Approach for Inhibiting Protein-Protein Interactions, Recommanded Product: 2-Chloro-4-hydroxyphenylboronic acid, the publication is Journal of Medicinal Chemistry (2004), 47(12), 3111-3130, database is CAplus and MEDLINE.

Fragment assembly has shown promise for discovering small-mol. antagonists for difficult targets, including protein-protein interactions. Here, the authors describe a process for identifying a 60 nM inhibitor of the interleukin-2 (IL-2)/IL-2 receptor (IL-2Rα) interaction. By use of fragment-based approaches, a compound with millimolar affinity was evolved to a hit series with low micromolar activity, and these compounds were optimized into a lead series with nanomolar affinity. Fragment assembly was useful not only for hit identification, but also for lead optimization. Throughout the discovery process, biophys. methods and structural biol. demonstrated that compounds bound reversibly to IL-2 at the IL-2 receptor binding site.

Perez-Rodriguez, Santiago published the artcileHighly twisted adamantyl arotinoids: Synthesis, antiproliferative effects and RXR transactivation profiles, SDS of cas: 33697-81-3, the publication is European Journal of Medicinal Chemistry (2009), 44(6), 2434-2446, database is CAplus and MEDLINE.

I (R = H, MeOCH₂CH₂OCH₂; R¹ = R² = H; R¹R² = CH:CH) and II (R = H, MeOCH₂CH₂OCH₂) are prepared as novel adamantyl biaryl arotinoids with decreased binding to retinoic acid receptors but with anticancer activity (by selective induction of apoptosis in cancer cells). I and II are prepared using Suzuki coupling reactions of an adamantylphenylboronic acid with a trifloxyphenylacetate, a trifloxycinnamate, and a trifloxynaphthoate. I (R = H, MeOCH₂CH₂OCH₂; R¹ = R² = H; R¹R² = CH:CH) show significant antiproliferative activity in several human cancer cell lines, with the anticancer activity correlated to the induction of apoptosis as measured by caspase activity. I (R = H, MeOCH₂CH₂OCH₂; R¹ = R² = H; R¹R² = CH:CH), while devoid of retinoic acid receptor binding capacity, transactivate the retinoid X receptor α.

Farrell, Wesley S. published the artcilePrecision, Tunable Deuterated Polyethylene via Polyhomologation, Name: N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Macromolecules (Washington, DC, United States) (2019), 52(15), 5741-5749, database is CAplus.

The ability to introduce isotopic labeling in a controlled fashion into polymers has long been an area of keen interest, as it allows for anal. by methods such as small-angle neutron scattering. In this work, polyhomologation (also known as “C1 polymerization”) of a deuterated ylide was performed, yielding linear polyethylene of high deuterium content. Copolymerization with the protonated analog allowed for the preparation of statistical copolymers, in which linear polyethylene with a uniform and tunable amount of deuterium is obtained. The amount of deuterium present, as well as its uniform distribution, is supported by vibrational spectroscopy, size-exclusion chromatog. with IR detection, and ²H NMR spectroscopy. This technique was extended to prepare a precision triblock copolymer in which the chain-ends are selectively deuterated. All polymers reported are of narrow dispersity, and will find use in myriad measurements sensitive to deuterium labeling, most notably small-angle neutron scattering.

Aspuria, E. T. published the artcileGFP accumulation controlled by an auxin-responsive promoter as a non-destructive assay to monitor early auxin response, HPLC of Formula: 33697-81-3, the publication is Plant Cell Reports (2002), 21(1), 52-57, database is CAplus.

We have constructed transgenic Arabidopsis lines that contain a gene for green fluorescent protein (GFP) under the control of auxin-responsive domains A and B of the promoter from the pea PS-IAA4/5 gene. The chimeric transgene was named BA-mgfp5-ER. GFP was detected after the application of indole-3-acetic acid at concentrations as low as 100 nM in epidermal cells in the root elongation zone. The induction of the reporter gene was highly specific to auxin and was correlated with the auxin-induced change in epidermal cell shape. No GFP accumulation was observed in the lateral root meristem that was formed as a result of exogenous auxin application. These results suggest that auxin signals were transmitted through several distinct pathways depending on the cell type. The intensity of the GFP signal was strong enough to be observed through the plastic lid of the culture dish using a dissecting microscope, thereby enabling GFP expression to be monitored in an aseptic environment. Thus, the BA-mgfp5-ER transgenic plant can be a powerful tool for screening mutants that are defective in auxin signaling and the expression of early auxin-response genes.

Lupi, Michela published the artcileResolution of a Configurationally Stable Hetero[4]helicene, Formula: C10H15ClO3S, the publication is Molecules (2022), 27(4), 1160, database is CAplus and MEDLINE.

Authors developed an efficient chem. resolution of racemic hydroxy substituted dithia-aza[4]helicenes (DTA[4]H) 1(OH) using enantiopure acids as resolving agents. The better diastereomeric separation was achieved on esters prepared with (1S)-(-)-camphanic acid. Subsequent simple manipulations produced highly optically pure (≥ 99% enantiomeric excess) (P) and (M)-1(OH) in good yields. The role of the position where the chiral auxiliary is inserted (cape- vs. bay-zone) and the structure of the enantiopure acid used on successful resolution are discussed.

The author are constructing the “Percellome Database” containing many transcriptomes of mice exposed to a series of chems. to elucidate the mol. mechanism of toxicity and to develop toxicity prediction technol. Acute toxicity of a chem. can be predicted to a certain extent by searching the similarity of the transcriptomes obtained by the single-dose exposure experiments In addition, the author are analyzing the relation between the transcriptome and the epigenome i.e. histone modification and genomic DNA methylation to understand the mol. mechanism of the repeated dose toxicity. The author are attempting to expand the scale and improve the efficiency of the anal. by introducing artificial intelligence technologies. This approach should maximize the use of toxicogenomics technol. for optimizing the exptl. protocols for repeated dose toxicity studies towards 3Rs principle, and optimizing the process of in silico toxicity prediction by combining the available big data.

Solvent effect, SDS of cas: 866-23-9, the publication is Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (1974), 30A(11), 2121-31, database is CAplus.

The association constants, (Ka), entropy, and enthalpy (ΔH) for the H-bonding of PhSH with 6 phosphoryl compounds, e.g., (EtO)2P(O)CCl3, were determined using the Hiquchi plot. ΔH and log Ka were both linearly dependent on the change in NMR chem. shift, Δδx, and with ir frequency shift δυSH, and δΔx and σν were linearly related. On going from CCl4 to cyclohexane solvent Ka and -δH were greatly increased whereas δx and δΔx were considerably decreased. A relation between the energy changes between S-H and C-H and S-H and O-H proton donors was established.

Sauerberg, Per published the artcileIdentification and Synthesis of a Novel Selective Partial PPARδ Agonist with Full Efficacy on Lipid Metabolism In Vitro and In Vivo, Application of 3-Chloro-4-hydroxyphenylacetic acid, the publication is Journal of Medicinal Chemistry (2007), 50(7), 1495-1503, database is CAplus and MEDLINE.

The aim was to identify a novel selective PPARδ agonist with full efficacy on free fatty acid (FFA) oxidation in vitro and plasma lipid correction in vivo. Using the triple PPARα,γ,δ agonist 1 (I) as the structural starting point, we wanted to investigate the possibility of obtaining selective PPARδ agonists by modifying only the acidic part of 1, while holding the lipophilic half of the mol. constant The structure-activity relationship was guided by in vitro transactivation data using the human PPAR receptors, FFA oxidation efficacy performed in the rat muscle L6 cell line, and in vivo rat pharmacokinetic properties. Compound 7 ([4-[3,3-bis-(4-bromo-phenyl)-allylthio]-2-chloro-phenoxy]-acetic acid) was identified as a selective, partial agonist with good oral pharmacokinetic properties in rat. Chronic treatment of high fat fed ApoB100/CETP-Tgn mice with 7 corrected the plasma lipid parameters and improved insulin sensitivity. These data suggest that selective PPARδ agonists have the potential to become a novel treatment of dyslipidemia.
