We report a comprehensive study on novel, highly efficient, and biodegradable hybrid mol. transporters. To this end, we designed a series of cell-penetrating, cube-octameric silsesquioxanes (COSS), and investigated cellular uptake by confocal microscopy and flow cytometry. A COSS with dense spatial arrangement of guanidinium groups displayed fast uptake kinetics and cell permeation at nanomolar concentrations in living HeLa cells. Efficient uptake was also observed in bacteria, yeasts, and archaea. The COSS-based carrier was significantly more potent than cell-penetrating peptides (CPPs) and displayed low toxicity. It efficiently delivered a covalently attached cytotoxic drug, doxorubicin, to living tumor cells. As the uptake of fluorescently labeled carrier remained in the presence of serum, the system could be considered particularly attractive for the in vivo delivery of therapeutics.

Kaneyasu, Tomoko published the artcileAuxin response, but not its polar transport, plays a role in hydrotropism of Arabidopsis roots, Category: chlorides-buliding-blocks, the publication is Journal of Experimental Botany (2007), 58(5), 1143-1150, database is CAplus and MEDLINE.

Plants are sessile in nature, and need to detect and respond to many environmental cues in order to regulate their growth and orientation. Indeed, plants sense numerous environmental cues and respond via appropriate tropisms, and it is widely accepted that auxin plays an important role in these responses. Recent analyses using Arabidopsis have emphasized the importance of polar auxin transport and differential auxin responses to gravitropism. Even so, the involvement of auxin in hydrotropism remains unclear. To clarify whether or not auxin is involved in the hydrotropic response, Arabidopsis seedlings were treated with inhibitors of auxin influx (3-chloro-4-hydroxyphenylacetic acid), efflux (1-naphthylphthalemic acid and 2,3,5-triiodobenzoic acid), and response (p-chlorophenoxyisobutylacetic acid), and their effects were examined on both hydrotropic and gravitropic responses. In agreement with previous reports, gravitropism was inhibited by all the chems. tested. By contrast, only an inhibitor of the auxin response (p-chlorophenoxyisobutylacetic acid) reduced hydrotropism, whereas inhibitors for influx or efflux of auxin had no effect. These results suggest that auxin response, apart from its polar transport, plays a definite role in hydrotropic response, and will evoke a new concept for the auxin-mediated regulation of tropisms.

Goestl, Robert published the artcileSterically crowding the bridge of dithienylcyclopentenes for enhanced photoswitching performance, SDS of cas: 219537-97-0, the publication is Chemistry – A European Journal (2012), 18(45), 14282-14285, S14282/1-S14282/28, database is CAplus and MEDLINE.

Diarylethenes (DAEs) are photochromic mols. with outstanding physicochem. properties. They are ideal for incorporation into materials for optoelectronics because of their superior switching properties. DAEs undergo a reversible 6p electrocyclic reaction upon irradiation with light. The efficiency of the photocyclization reaction is governed by its quantum yield, which is dependent on the equilibrium between the parallel (p) and the antiparallel (ap) conformation. Steric repulsion, which is largely independent of the environment, can also be used to influence the equilibrium between p and ap conformation. Herein, we report a synthetically straightforward method for introducing bulky substituents into the bridge moiety of dithienylcyclopentenes, thus leading to derivatives exhibiting higher photocyclization quantum yield.

Electron-rich arenes are oxidatively photochlorinated in the presence of catalytic amounts of bromide ions, visible light, and 4CzIPN as organic photoredox catalyst. The substrates are brominated in situ in a first photoredox-catalyzed oxidation step, followed by a photocatalyzed ipso-chlorination, yielding the target compounds in high ortho/para regioselectivity. Dioxygen serves as a green and convenient terminal oxidant. The use of aqueous hydrochloric acid as the chloride source reduces the amount of saline byproducts.

Esmaeilzadeh, Pegah published the artcileStimuli-responsive multilayers based on thiolated polysaccharides that affect fibroblast cell adhesion, HPLC of Formula: 7080-50-4, the publication is ACS Applied Materials & Interfaces (2018), 10(10), 8507-8518, database is CAplus and MEDLINE.

Control of the biomaterial properties through stimuli-responsive polymeric platforms has become an essential technique in recent biomedical applications. A multilayer system of thiolated chitosan (t-Chi) and thiolated chondroitin sulfate (t-CS), consisting of five double layers ([t-Chi/t-CS]₅), was fabricated here by applying a layer-by-layer coating strategy. To represent a novel class of chem. tunable nanostructures, the ability to cross-link pendant thiol groups was tested by a rise from pH 4 during layer formation to pH 9.3 and a more powerful chem. stimulus by using chloramine-T (ChT). Following both treatments, the resulting multilayers showed stimuli-dependent behavior, as demonstrated by their content of free thiols, wettability, surface charge, elastic modulus, roughness, topog., thickness, and binding of fibronectin. Studies with human dermal fibroblasts further demonstrated the favorable potential of the ChT-responsive multilayers as a cell-adhesive surface compared to pH-induced crosslinking. Because the [t-Chi/t-CS]₅ multilayer system is responsive to stimuli such as the pH and redox environment, multilayer systems with disulfide bond formation may help to tailor their interaction with cells, film degradation, and controlled release of bioactive substances like growth factors in a stimuli-responsive manner useful in future wound healing and tissue engineering applications.

Nadirova, Maryana A. published the artcileCascade of the Hinsberg / IMDAF reactions in the synthesis 2-arylsulfonyl-3a,6-epoxyisoindoles and 4a,7-epoxyisoquinolines in water, Name: 4-Chloro-3-(trifluoromethyl)benzenesulfonyl Chloride, the publication is Tetrahedron (2021), 132032, database is CAplus.

N-Furfuryl allylamines, readily accessible from corresponding furfurals or furfuryl amines, react with a broad range of aryl sulfonyl chlorides with the formation of a 3a,6-epoxyisoindoles I [Ar = Ph, 2-thienyl, Ts, etc.; R¹ = H, I, Et, etc.; R² = H, Br, Me] in one synthetic stage was reported. Usually, in boiling water, the interaction sequence involved two consecutive steps: the Hinsberg reaction and the intramol. Diels-Alder furane (IMDAF) reaction. The scope and limitations of the proposed method were thoroughly investigated, and it was revealed that the key [4+2] cycloaddition step proceeded through an exo-transition state, giving rise to the exclusive formation of a single diastereomer of the target heterocycle. The method allowed the ability to obtain N-sulfaryl-substituted 3a,6-epoxyisoindoles I and 4a,7-epoxyisoquinolines, which were potentially useful substrates for further transformations and subsequent bioscreening, in particular antimicrobial activity.

Transformations of anionic Cu^II chlorocomplexes have been studied under conditions of catalytic exchange reactions between carbon tetrachloride and n-alkanes. It was shown that chlorocuprates are just precursors and are easily reduced to the genuine catalysts, i.e., to the resp. Cu^I complexes. Both the composition and the geometric structure of the precursor (CuCl₄^2-) and, probably, the active site (CuCl₃^2-) have been investigated by several techniques (UV-vis spectroscopy, ESR, extended X-ray absorption fine structure (EXAFS), X-ray absorption near-edge structure (XANES), and static magnetic measurements). The dependence of the metathesis velocity on the [Cl^–]/[Cu] ratio was found to exhibit a maximum most likely corresponding to the highest content of trichlorocuprite CuCl₃^2-.

Balinge, Kamlesh Rudreshwar published the artcileFacile access to polymer supported zinc-salen complex: highly efficient heterogeneous catalyst for synthesizing hydantoins, thiohydantoins and Schiff bases in aqueous medium, Application In Synthesis of 3696-23-9, the publication is Research on Chemical Intermediates (2018), 44(3), 2075-2097, database is CAplus.

The synthesis of polymer supported zinc-salen complex (PS-Zn-salen) is described. The mononuclear zinc(II)-salen complex was characterized by Fourier-transform NMR spectroscopy, energy-dispersive X-ray spectroscopy, Fourier transform IR spectrophotometry (FT-IR), thermogravimetric anal., SEM, surface area and pore size distribution by Brunauer-Emmett-Teller. The synthesized PS-Zn-salen complex used as a recyclable heterogeneous catalyst for the efficient synthesis of hydantoins, thiohydantoins and Schiff bases in an aqueous medium. The isolated yields of hydantoins, thiohydantoins and Schiff bases achieved up to 89, 95 and 94%, resp. In spite of conventional heterogeneous catalysts, current PS-Zn-salen complex shows thermal stability up to 280 °C. Moreover, the catalyst could be recovered easily by simple filtration and reused for next run with slightly declining its activity up to six successive runs. The FT-IR spectrum of recycle catalyst after 6th run confirmed that the catalyst was stable during the course of a reaction. The leaching of metal from the PS-Zn-salen is negligible, which was confirmed by AAS and hot filtration test.
