Peristyy, Anton published the artcileIon-exchange properties of High Pressure High Temperature synthetic diamond, HPLC of Formula: 23616-79-7, the publication is Diamond and Related Materials (2017), 131-139, database is CAplus.

The adsorption and chromatog. properties of microparticulated diamond (1-2 μm and 4-6 μm fractions) from high pressure and high temperature synthesis (HPHT diamond) are investigated, with a focus on their cation-exchange capacity. Several adsorbents were prepared, either by wet oxidation of the surface of HPHT with H₂O₂/H₂SO₄ or HNO₃/H₂SO₄ mixtures, or by oxidation in air at 700 °C, or following a four-step reduction using LiAlH₄ and n-butyllithium. The zeta-potential profiles as a function of pH and ion-exchange capacities were measured for the prepared adsorbents as well as isotherms of adsorption. The ion-exchange selectivity of oxidised HPHT diamond was studied towards alkali, alk.-earth and transition metal cations.

Afonin, Sergii published the artcileIn Vivo Behavior of the Antibacterial Peptide Cyclo[RRRWFW], Explored Using a 3-Hydroxychromone-Derived Fluorescent Amino Acid, Safety of 2-Chlorotrityl chloride, the publication is Frontiers in Chemistry (Lausanne, Switzerland) (2021), 688446, database is CAplus and MEDLINE.

Labeling biomols. with fluorescent labels is an established tool for structural, biochem., and biophys. studies; however, it remains underused for small peptides. In this work, an amino acid bearing a 3-hydroxychromone fluorophore, 2- amino-3-(2-(furan-2-yl)-3-hydroxy-4-oxo-4H-chromen-6-yl)propanoic acid (FHC), was incorporated in a known hexameric antimicrobial peptide, cyclo[RRRWFW] (cWFW), in place of aromatic residues. CD spectropolarimetry and antibacterial activity measurements demonstrated that the FHC residue perturbs the peptide structure depending on labeling position but does not modify the activity of cWFW significantly. FHC thus can be considered an adequate label for studies of the parent peptide. Several anal. and imaging techniques were used to establish the activity of the obtained labeled cWFW analogs toward animal cells and to study the behavior of the peptides in a multicellular organism. The 3-hydroxychromone fluorophore can undergo excited-state intramol. proton transfer (ESIPT), resulting in double-band emission from its two tautomeric forms. This feature allowed us to get insights into conformational equilibrium of the labeled peptides, localize the cWFW analogs in human cells (HeLa and HEK293) and zebrafish embryos, and assess the polarity of the local environment around the label by confocal fluorescence microscopy. We found that the labeled peptides efficiently penetrated cancerous cells and localized mainly in lipid-containing and/or other nonpolar subcellular compartments. In the zebrafish embryo, the peptides remained in the bloodstream upon injection into the cardinal vein, presumably adhering to lipoproteins and/or microvesicles. They did not diffuse into any tissue to a significant extent during the first 3 h after administration. This study demonstrated the utility of fluorescent labeling by double-emission labels to evaluate biol. active peptides as potential drug candidates in vivo.

Tosi, Umberto published the artcileReal-Time, in Vivo Correlation of Molecular Structure with Drug Distribution in the Brain Striatum Following Convection Enhanced Delivery, Computed Properties of 6249-56-5, the publication is ACS Chemical Neuroscience (2019), 10(5), 2287-2298, database is CAplus and MEDLINE.

The blood-brain barrier (BBB) represents a major obstacle in delivering therapeutics to brain lesions. Convection-enhanced delivery (CED), a method that bypasses the BBB through direct, cannula-mediated drug delivery, is one solution to maintaining increased, effective drug concentration at these lesions. CED was recently proven safe in a phase I clin. trial against diffuse intrinsic pontine glioma (DIPG), a childhood cancer. Unfortunately, the exact relationship between drug size, charge, and pharmacokinetic behavior in the brain parenchyma are difficult to observe in vivo. PET imaging of CED-delivered agents allows us to determine these relationships. In this study, we label different modifications of the PDGFRA inhibitor dasatinib with fluorine-18 or via a nanofiber-zirconium-89 system so that the effect of drug structure on post-CED behavior can accurately be tracked in vivo, via PET. Relatively unchanged bioactivity is confirmed in patient- and animal-model-derived cell lines of DIPG. In naïve mice, significant individual variability in CED drug clearance is observed, highlighting a need to accurately understand drug behavior during clin. translation. Generally, the half-life for a drug to clear from a CED site is short for low mol. weight dasatinib analogs that bare different charge; 1-3 (1, 32.2 min (95% CI: 27.7-37.8), 2, 44.8 min (27.3-80.8), and 3, 71.7 min (48.6-127.6) minutes) and is much longer for a dasatinib-nanofiber conjugate, 5, (42.8-57.0 days). Positron emission tomog. allows us to accurately measure the effect of drug size and charge in monitoring real-time drug behavior in the brain parenchyma of live specimens.

Kalcic, Filip published the artcilePolysubstituted Pyrimidines as mPGES-1 Inhibitors: Discovery of Potent Inhibitors of PGE₂ Production with Strong Anti-inflammatory Effects in Carrageenan-Induced Rat Paw Edema, SDS of cas: 870778-91-9, the publication is ChemMedChem (2020), 15(15), 1398-1407, database is CAplus and MEDLINE.

We report an extensive structure-activity relationship optimization of polysubstituted pyrimidines that led to the discovery of 5-butyl-4-(4-benzyloxyphenyl)-6-phenylpyrimidin-2-amine, and its difluorinated analog. These compounds are sub-micromolar inhibitors of PGE₂ production (IC₅₀ as low as 12 nM). In order to identify the mol. target of anti-inflammatory pyrimidines, we performed extensive studies including enzymic assays, homol. modeling and docking. The difluorinated analog simultaneously inhibits two key enzymes of the arachidonic acid cascade, namely mPGES-1 and COX-2, with mPGES-1 inhibition being the principal mechanism of action. Other pyrimidines studied are potent mPGES-1 inhibitors with no observed inhibition of COX-1/2 enzymes. Moreover, the two most potent compounds proved to be significantly effective in vivo in a model of acute inflammation, suppressing carrageenan-induced rat paw edema by 36 and 46%. The promising results of this study warrant further preclin. evaluation of selected anti-inflammatory candidates.

Gee, Clifford T. published the artcileFragment Screening and Druggability Assessment for the CBP/p300 KIX Domain through Protein-Observed ¹⁹F NMR Spectroscopy, COA of Formula: C8H7ClO3, the publication is Angewandte Chemie, International Edition (2015), 54(12), 3735-3739, database is CAplus and MEDLINE.

¹⁹F NMR spectroscopy of labeled proteins is a sensitive method for characterizing structure, conformational dynamics, higher-order assembly, and ligand binding. Fluorination of aromatic side chains has been suggested as a labeling strategy for small-mol. ligand discovery for protein-protein interaction interfaces. Using a model transcription factor binding domain of the CREB binding protein (CBP)/p300, KIX, we report the first full small-mol. screen using protein-observed ¹⁹F NMR spectroscopy. Screening of 508 compounds and validation by ¹H-¹⁵N HSQC NMR spectroscopy led to the identification of a minimal pharmacaphore for the MLL-KIX interaction site. Hit rate anal. for the CREB-KIX and MLL-KIX sites provided a metric to assess the ligandability or “druggability” of each interface informing future medicinal chem. efforts. The structural information from the simplified spectra and data collection speed, affords a new screening tool for anal. of protein interfaces and discovery of small mols.

Both mols. showed high configurational stability and distinct functional properties, which were attributed to the fusing mode of [5]helicene with the pyrene and mol. symmetry. The estimated Gibbs activation energy for enantiomerization of 2 is one of the highest reported values for any π-conjugated mols. incorporating [5]helicene moiety.
