High-quality biocompatible magnetic iron oxide (Fe₃O₄) nanocrystals were developed through a ligand exchange process of hydrophobically capped nanocrystals with hydrophilic mols. By simple modulation of the nanocrystal surface ligand charge properties, the authors have been able to prepare magnetic nanocrystals with excellent intracellular labeling capabilities that efficiently label a variety of cell types without the need for addnl. transport facilitating agents. The excellent intracellular labeling capability of the newly developed cationic WSIO has further led to successful MRI monitoring of the migration of neural stem cells in rat spinal cord. The magnetic nanocrystals developed here have great potential in applications for labeling of various cell types and also the monitoring of cell-based medical treatments and cancer metastasis.

This Letter describes the further lead optimization of the VU0486321 series of mGlu₁ pos. allosteric modulators (PAMs), focused on addressing the recurrent issue of plasma instability of the phthalimide moiety. Here, the authors evaluated a number of phthalimide bioisosteres, and ultimately identified isoindolinones as the ideal replacement that effectively address plasma instability, while maintaining acceptable mGlu₁ PAM potency, DMPK profile, CNS penetration and mGluR selectivity.

Vilceanu, R. published the artcileStructure-activity correlations for the toxicity of organic phosphorus compounds of the Schrader type, Quality Control of 866-23-9, the publication is Analele Universitatii din Timisoara, Stiinte Fizice-Chimice (1977), 15(1), 61-77, database is CAplus.

The toxicity in mice of 71 phosphororg. compounds of the Schrader type, R¹R²PO₂R³, was correlated with parameters for intermol. forces [number of atoms with lone electron pairs (HA), molar refractions (R), Hammett constants of the R³ groups (H), number of aromatic cycles (AR), electron attracting character in charge transfer (CT)] and minimal steric difference (MSD), with respect to acetylcholine. The best linear correlational equation obtained (71 compounds, 6 parameters) was: A = 0.555 + 0.476(HA)-0.017(R) + 0.343(H)-0.402(AR) + 0.611(CT)-0.063(MSD), where A = -lgLD₅₀. This correlation was obtained for a very wide range of chem. structures with the R¹, R² and R³ groups.

Hydrophilic polymers having pendant groups of carboxylates or sulfonates have been used as a polymer support for chiral 1,2-diamine monosulfonamides. The polymeric chiral complex prepared from the polymer-supported chiral ligand with ruthenium dichloride p-cymene was used in the asym. transfer hydrogenation of prochiral ketones in water. The balance between hydrophilicity and hydrophobicity of the polymer support influenced both the reactivity and the enantioselectivity of the reaction in water. The chiral polymeric complex having a quaternary ammonium salt structure as the pendant group worked well in water. In most cases the polymer-supported catalyst having a quaternary ammonium sulfonate pendant group showed superior enantioselectivity compared to the corresponding nonsupported model catalyst in the solution system. The polymeric catalysts can be reused without loss of catalytic activity.

Su, Yuan-Hsiao published the artcileSolution-phase parallel synthesis and screening of anti-tumor activities from fenbufen and ethacrynic acid libraries, Synthetic Route of 33697-81-3, the publication is Bioorganic & Medicinal Chemistry Letters (2011), 21(5), 1320-1324, database is CAplus and MEDLINE.

The derivatives with fenbufen and ethacrynic acid core compounds was synthesized through a facial preparation of 1-amino-4-azidobutane. The subsequent coupling with 102 members of carboxylic acids afforded amide products. The in situ screening using colorimetric assay with 3-(4.5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide showed that fenbufen but not ethacrynic acid Bu amide members displayed the cytotoxicities to tumor cells substantially, including two human cell lines (MCF7 and A549) and two murine cell lines (C26 and TRAMP-C1). Three fenbufen analogs, e.g. I, II and III, were found to have a good anti-tumor activity comparable to cisplatin.

Selective oxidation of organic substrates by environment-friendly oxidizing agents is an important ingredient of the sustainable chem. industry. Here we report a comprehensive study in the field of metal peoroxocomplex catalysis for the selective liquid phase oxidation of various organic substrates. A number of well-defined bi-functional tungsten complex catalysts with tetra nuclear structure {PO4[WO(O₂)₂]₄}^3- in combination with a phase-transfer agents were synthesized. The structural properties were thoroughly studied using of IR, Raman and EXAFS spectroscopy. By combining different spectroscopy techniques were able to elucidate the effect of quaternary ammonium cations on the structural properties of the resulting peroxo complexes. The catalytic properties of these well-defined material were then evaluated in bi-phasic selective oxidation of cyclooctene, Me oleate and N-phosphonomethyliminodiacetic acid with hydrogen peroxide under mild conditions. For every substrate we were able to achieve high conversion at the selectivity towards a target product close to 100%.

Xiao, Chunsheng published the artcileSide chain impacts on pH- and thermo-responsiveness of tertiary amine functionalized polypeptides, SDS of cas: 4584-49-0, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (2014), 52(5), 671-679, database is CAplus.

The systemic investigation of the structural impacts of side chains on the pH- and thermo-responsiveness of tertiary amine functionalized poly(L-glutamate)s (TA-PGs) was carried out. The TA-PGs polymers were effectively synthesized by Cu(I)-catalyzed azide-alkyne cycloaddition click reaction of azido tertiary amines with poly(γ-propargyl-L-glutamate) (PPLG). Turbimetric measurements were performed to characterize the pH- and temperature-induced phase transition of TA-PGs in aqueous solution, which suggested a structural dependence of the properties on the N-substituted groups and the “linkers” between 1,2,3-triazole ring and the tertiary amine groups in the side chains. In detail, the pH responsive properties of TA-PGs were basically determined by the hydrophobicity of the N-substituted groups in the side chains and the pH transition point (pH_t) decreased as the increasing hydrophobicity of the N-substituted groups, while the temperature-responsiveness of TA-PGs were affected by either the N-substituted groups or the “linkers.” TA-PGs with a moderate N-substituted amine group (e.g., DEA, PR, and PD) or a branched “linker” (e.g., iso-propylene and 2-methylpropylene group) were more likely to express the LCST-type phase transition tuned by pH variation. These structure-property relationships revealed in this study would help to develop the applications of TA-PGs in smart drug delivery systems. © 2013 Wiley Periodicals, Inc. J. Polym.

A series of new benzothiazole derivatives containing dimethylpyrazole I [R = H, n-pentyl, benzyl, etc.] were synthesized and evaluated for their anticonvulsant activity, neurotoxicity and cytotoxicity by using the maximal electroshock (MES), rotarod neurotoxicity (TOX) and MTT colorimetric assay. Among the compounds studied, four compounds I [R = Bu, n-pentyl, 2-fluorobenzyl, 2,6-dichlorobenzyl] showed better anticonvulsant than the others at 300 mg/kg and they also showed anticonvulsant activity at the dose of 100 mg/kg. All the synthetic compounds I showed lower neurotoxicity and little cytotoxicity, so that the compounds, which with better activities, also had higher protective index. In particular, the compound I [R = 2-fluorobenzyl] showed better activity with an ED₅₀ value of 160.4 mg/kg and higher protective index (PI) values of 2.74 in the MES test than the standard drugs sodium valproate, which used as pos. controls in this study. After that the compound I [R = 2-fluorobenzyl] demonstrated antagonistic activity against seizures induced by pentylenetetrazol, which proved compound I [R = 2-fluorobenzyl] may be exert activity through effecting GABAergic neurotransmission.
