Contino, Marialessandra;Guglielmo, Stefano;Riganti, Chiara;Antonello, Giulia;Perrone, Maria Grazia;Giampietro, Roberta;Rolando, Barbara;Fruttero, Roberta;Colabufo, Nicola A. research published 《 One molecule two goals: A selective P-glycoprotein modulator increases drug transport across gastro-intestinal barrier and recovers doxorubicin toxicity in multidrug resistant cancer cells》, the research content is summarized as follows. In the present study a series of tetrahydroisoquinoline derivatives were synthesized and evaluated for their activity towards three ABC transporters, P-gp, MRP1 and BCRP. The compounds proved to be selective against P-gp. One of them, 8b, displayed activity in the nanomolar range (EC₅₀ = 94 nM). Thus, compound 8b was tested for its ability to restore the cytotoxic activity of a well-known anti-cancer agent and P-gp substrate, doxorubicin, as first proof of concept. Moreover, compound 8b was also tested in an in vitro model of competent gastro-intestinal (GI) barrier (Caco-2 cells) for its ability to inhibit P-gp, present on luminal side, and increase the apical-to-basolateral transport of several structurally uncorrelated drugs, belonging to different therapeutic areas but actively excreted by P-gp. Notably the transport of the drugs across the GI barrier was increased by a concentration of 8b devoid of toxicity and of perturbing effects on barrier function. An in vitro simulated digestion process was set up: interestingly the effect of 8b on the transport of digoxin was preserved also after the simulated digestion process. This result may suggest 8b as a safe and effective P-gp modulator that can increase the bioavailability of a wide spectrum of drugs administered per os, improving their transport across the GI barrier.

Chen, Sung-Po R.;Bobrin, Valentin A.;Jia, Zhongfan;Monteiro, Michael J. research published 《 Temperature-Directed Formation of Anisotropic Kettlebell and Tadpole Nanostructures in the Absence of a Swelling-Induced Solvent》, the research content is summarized as follows. Anisotropic Janus (“snowman”) nanoparticles with a single protrusion are currently made via the solvent swelling-induced method. Here, we demonstrate without the aid of toxic solvents a generally applicable method for the formation of anisotropic polymer nanoparticles directly in water by controlling polymer mobility through tuning its glass transition temparature (Tg). Spherical structures, formed immediately after the emulsion polymerization, transformed into uniform tadpoles (with head diameter ∼60 nm and tail length ∼130 nm) through the protrusion of a single cylindrical tail when cooled to a temparature above the Tg of the polymer. Cooling the spheres to below the Tg produced kinetically trapped kettlebell structures that could be freeze-dried and rehydrated without any structural change. These unique kettlebells could transform into uniform tadpoles by heating above the Tg, representing a triggered and on-demand structural reorganization.

Chen, Sung-Po R.;Jia, Zhongfan;Bobrin, Valentin A.;Monteiro, Michael J. research published 《 UV-Cross-Linked Polymer Nanostructures with Preserved Asymmetry and Surface Functionality》, the research content is summarized as follows. Polymer nanostructures can be designed with tailored properties and functions by varying their shape, chem. compositions, and surface functionality. The poor stability of these soft materials in solvent other than water can be overcome by introducing cross-links. However, crosslinking complex morphologies remains a challenge. Here, by using the temperature-directed morphol. transformation method, we show that the sym. (nanoworm) and asym. (tadpole) nanostructure cores can be UV-cross-linked through the coupling of styrene and para-chlorostyrene units found in the core by irradiating at 254 nm for up to 5 h. Once cross-linked, these nanostructures maintain their structure in organic solvent, further allowing us to couple on a water-insoluble pro-fluorescent probe with high efficiency.

Inspired by the widely antiphytopathogenic application of diversified derivatives from natural sources, cryptolepine and its derivatives were subsequently designed, synthesized, and evaluated for their antifungal activities against four agriculturally important fungi Rhizoctonia solani, Botrytis cinerea, Fusarium graminearum, and Sclerotinia sclerotiorum. The results obtained from in vitro assay indicated that compounds showed great fungicidal property against B. cinerea (EC₅₀ < 4μg/mL); especially, I presented significantly prominent inhibitory activity with an EC₅₀ of 0.027μg/mL. In the pursuit of further expanding the antifungal spectrum of cryptolepine, ring-opened compound II produced better activity with an EC₅₀ of 3.632μg/mL against R. solani and an EC₅₀ of 5.599μg/mL against F. graminearum. Furthermore, I was selected to be a candidate to investigate its preliminary antifungal mechanism to B. cinerea, revealing that not only spore germination was effectively inhibited and the normal physiol. structure of mycelium was severely undermined but also detrimental reactive oxygen was obviously accumulated and the normal function of the nucleus was fairly disordered. Besides, in vivo curative experiment against B. cinerea found that the therapeutic action of I was comparable to that of the pos. control azoxystrobin. These results suggested that compound I could be regarded as a novel and promising agent against B. cinerea for its valuable potency.

Chen, Zhangxin;Mei, Shiwei;Li, Weijun;Xu, Ning;Dong, Yujie;Jin, Yanxian;Ouyang, Mi;Zhang, Cheng research published 《 Study of multi-electron redox mechanism via electrochromic behavior in hexaazatrinaphthylene-based polymer as the cathode of lithium-organic batteries》, the research content is summarized as follows. The charging and discharging mechanism of lithium-organic batteries has always been a challenging issue due to the lack of popularity of in situ characterization technol. during the charge/discharge process. In this article, a novel open lithium battery test combining the in situ electrochem. and UV spectral tests is firstly studied to explore the multi-electron redox mechanism of hexaazatrinaphthylene-based polymers as a cathode of lithium-organic batteries. Two triphenylamine-hexanazonaphthalene structure conjugated microporous polymers (PTPA-HATN and PDTPA-HATN) have been synthesized as models to study the charging and discharging mechanism of hexazanaphthalene. Both possess similar nanosphere morphol. and high surface area (~450 mA h g^-1) as well as abundant microporous structure. Using them as cathodes to explore the lithium battery performance, an obvious charge-discharge process with multi-electron redox characteristics can be observed in both, and the one with PTPA-HATN shows a higher discharge capacity (~168 mA h g^-1) and better rate performance than those of PDTPA-HATN in LiClO₄ electrolyte. Combining the in situ electrochem. and UV spectral results, a new multi-electron redox mechanism of hexanazonaphthalene-based polymer cathodes in lithium-organic batteries is proposed. Different from the previously reported mechanisms, the N and N lone electron pairs of the hexanazonaphthalene group in the polymer film will adsorb Li⁺ to form the N-Li-N bond in the electrolytes with low HF acid content accompanied with the red shift of absorption peak in the spectra under the open circuit voltage. During the discharge process, the N-Li-N bond will break and combine with the newly entered Li⁺ to form the N₂-Li₂ bond, resulting in a new large blueshift in the spectra. This work may provide new insight into the redox mechanism of functional groups of organic cathode materials via electrochromic behavior on the performance of lithium batteries.

A visible light-induced photocyanation of tertiary amines e.g., 1-((trimethylsilyl)methyl)piperidine by a stable, less-toxic and user-friendly CN reagent cyanobenziodoxolone (CBX) was developed. This cyanation process does not require any photocatalyst, oxidant, base or additives, and represents a set of extremely mild and succinct reaction conditions and a broad substrate scope. In addition to the frequently used N-aryl amine derivatives e.g, 2-thiomorpholinoacetonitrile, more challenging tertiary aliphatic amines (modified by a α-silyl substituent) can also be photocyanated smoothly. Mechanistic studies reveal that the cyanation reaction is enabled by an electron donor-acceptor (EDA) complex formed by the interaction between the amine and the cyanobenziodoxolone reagent.

Chaignon, Philippe;Petit, Benoit Eric;Vincent, Bruno;Allouche, Lionel;Seemann, Myriam research published 《 Methylerythritol Phosphate Pathway: Enzymatic Evidence for a Rotation in the LytB/IspH-Catalyzed Reaction》, the research content is summarized as follows. IspH/LytB, an oxygen-sensitive [4Fe-4S] enzyme, catalyzes the last step of the methylerythritol phosphate (MEP) pathway, a target for the development of new antimicrobial agents. This metalloenzyme converts (E)-4-hydroxy-3-methylbut-2-en-1-yl diphosphate (HMBPP) into the two isoprenoid precursors: isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). Here, the synthesis of (S)-[4-²H₁]HMBPP and (R)-[4-²H₁]HMBPP is reported together with a detailed NMR anal. of the products formed after their resp. incubation with E. coli IspH/LytB in the presence of the biol. reduction system used by E. coli to reduce the [4Fe-4S] center. (S)-[4-²H₁]HMBPP was converted into [4-²H₁]DMAPP and (E)-[4-²H₁]IPP, whereas (R)-[4-²H₁]HMBPP yielded [4-²H₁]DMAPP and (Z)-[4-²H₁]IPP, hence providing the direct enzymic evidence that the mechanism catalyzed by IspH/LytB involves a rotation of the CH₂OH group of the substrate to display it away from the [4Fe-4S].

Chen, Chien-Tien;Ho, Jih-Sen;Weng, Shu-Chih research published 《 Metal-Ion Specific Recognition with Amplified Transcription from Subnanometer to Submillimeter or Real-Time Domain by Self-Assembled Vanadyl Quartets》, the research content is summarized as follows. Vanadyl(V) complexes 1 and 2 bearing a nematic liquid crystal (LC) like a p-heptoxyphenyl group or a fluorous-tag p-nonafluoroheptoxyphenyl (NFH) group at the C5 position of the N-salicylidene template were designed and synthesized. Each complex was subjected to MVO₃-induced self-assembly to form metal-ion, encapsulated quartet clusters 3–M and 3′–M. The Na⁺ in cluster complex 3-Na or 3′-Na can be readily replaced by Rb⁺, Ag⁺, or Hg²⁺ in an aqueous layer to form cluster complexes by ion swapping at the H₂O/CDCl₃ bilayer interface. Selectivity profiles were examined with alkali-metal ions, Ag⁺, and Hg²⁺ through metal-ion competition experiments The 3′-Na has an exclusive selectivity for Hg²⁺ in the presence of Zn²⁺ and Cd²⁺. Cluster complexes 3–M were used as chiral dopants to nematic LC materials. The effects of the encapsulated metal ions within the alkali family and Ag⁺ on Cano’s line widths and helical pitch changes were viewed in wedge cells under a polarized microscope. Their correlations with the ionic radius were identified. The subnano information of the metal ions can thus be asym. amplified to Cano’s line spacings of the submilimeter domain. Conversely, the effects of the encapsulated alkali metal ions and Hg²⁺ in 3′–M on the interactions of their NFH tails toward fluorous silica gel (FSG) were performed via HPLC analyses. Their retention times became longer as the sizes of encapsulated, alkali metal ions increased. The increasing ion size from Na⁺ to Cs⁺ caused the four lower rim NFH tags of the cluster to be closer due to reduced cone angles. Their interactions among NFH tail groups on FSG became larger, thus leading to distinctive separations with t_R from 7.36 to 10.27 min. The retention time difference between 3′-Na and 3′-Hg on HPLC was ~3.6 min, resulting in discernible separation The individual ion size differences on the subnano scale can thus be amplified and unambiguously established in the real time domain.
