Xu, Jinhui published the artcileUnveiling Extreme Photoreduction Potentials of Donor-Acceptor Cyanoarenes to Access Aryl Radicals from Aryl Chlorides, Related Products of chlorides-buliding-blocks, the publication is Journal of the American Chemical Society (2021), 143(33), 13266-13273, database is CAplus and MEDLINE.

Since the seminal work of Zhang in 2016, donor-acceptor cyanoarene-based fluorophores, such as 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN), have been widely applied in photoredox catalysis and used as excellent metal-free alternatives to noble metal Ir- and Ru-based photocatalysts. However, all the reported photoredox reactions involving this chromophore family are based on harnessing the energy from a single visible light photon, with a limited range of redox potentials from -1.92 to +1.79 V vs SCE. Here, we document the unprecedented discovery that this family of fluorophores can undergo consecutive photoinduced electron transfer (ConPET) to achieve very high reduction potentials. One of the newly synthesized catalysts, 2,4,5-tri(9H-carbazol-9-yl)-6-(ethyl(phenyl)amino)isophthalonitrile (3CzEPAIPN), possesses a long-lived (12.95 ns) excited radical anion form, 3CzEPAIPN^•-*, which can be used to activate reductively recalcitrant aryl chlorides (E_red ≈ -1.9 to -2.9 V vs SCE) under mild conditions. The resultant aryl radicals can be engaged in synthetically valuable aromatic C-B, C-P, and C-C bond formation to furnish arylboronates, arylphosphonium salts, arylphosphonates, and spirocyclic cyclohexadienes.

Jin, Piaopiao published the artcileMulti-responsive diarylethene-phenolphthalein hybrids by multiple stimuli, COA of Formula: C15H14Cl2S2, the publication is Tetrahedron (2016), 72(35), 5488-5494, database is CAplus.

Photochromic diarylethene derivatives cherishing phenolphthalein moieties were designed and constructed. We present efforts to investigate their versatile performances in multi-responsive properties with multiple stimuli of light, acid/base and temperature/heat. Results show their fluorescence could be on-off switched not only by different lights but also by acid/base. Besides lights and acid/base controllable color change and fluorescence-changing, altering phase states could also tune their colors via different temperature, which is rare performance for diarylethene derivatives Especially, the photocyclization ratio is as high as 100% for compound 2o bearing two phenolphthalein groups. These versatile properties are helpful to the design of pH sensitive photoswitches, fluorescent sensors, and mol. logical gates.

Cao, Chaotun published the artcileQuantifying and fine adjusting the solid-state fluorescence wavelength of 1-thienyl-2-arylethylene, Recommanded Product: 1-(Chloromethyl)-4-(trifluoromethyl)benzene, the publication is Journal of Luminescence (2021), 117895, database is CAplus.

Thirty two 1-thienyl-2-arylethylene derivatives (XAEY) were synthesized and their solid-state fluorescence emission wavelengths Em (nm) were determined The effects of substituents X and Y on the fluorescence wavelengths were analyzed in detail. The quant. correlation anal. for the Em was carried out by employing the ground-state polarity parameters and excited-state parameters of the substituents X and Y. A quant. equation was obtained and its reliability was verified by the leave-one-out (LOO) method. The obtained results show: (1) For the compounds XAEY, when the group Y on the aryl group is fixed, the Em order is 2′-methyl-2-thienyl-AEY > 3-thienyl-AEY > 2-thienyl-AEY; when thienyl (X) is fixed, the Em of XAEY with electron-withdrawing group Y is longer than that of XAEY with electron-donating group Y; (2) The Em of XAEY can be finely adjusted by changing groups X and Y. That is, one can obtain a series of compounds with continuous fluorescence emission wavelength in range of 450-600 nm via selecting different groups X or Y. (3) The 2′-Me has an addnl. red shift effect on the Em of 2′- methyl-2-thienyl-AEY. The results of this paper can provide an important reference for studying theor. solid-state fluorescence emission spectra of organic compounds and designing corresponding fluorescent material mols.

Cruz-Migoni, Abimael published the artcileStructure-based development of new RAS-effector inhibitors from a combination of active and inactive RAS-binding compounds, Computed Properties of 944129-07-1, the publication is Proceedings of the National Academy of Sciences of the United States of America (2019), 116(7), 2545-2550, database is CAplus and MEDLINE.

The RAS gene family is frequently mutated in human cancers, and the quest for compounds that bind to mutant RAS remains a major goal, as it also does for inhibitors of protein-protein interactions. We have refined crystallization conditions for KRAS169Q61H-yielding crystals suitable for soaking with compounds and exploited this to assess new RAS-binding compounds selected by screening a protein-protein interaction-focused compound library using surface plasmon resonance. Two compounds, referred to as PPIN-1 and PPIN-2, with related structures from 30 initial RAS binders showed binding to a pocket where compounds had been previously developed, including RAS effector protein-protein interaction inhibitors selected using an intracellular antibody fragment (called Abd compounds). Unlike the Abd series of RAS binders, PPIN-1 and PPIN-2 compounds were not competed by the inhibitory anti-RAS intracellular antibody fragment and did not show any RAS-effector inhibition properties. By fusing the common, anchoring part from the two new compounds with the inhibitory substituents of the Abd series, we have created a set of compounds that inhibit RAS-effector interactions with increased potency. These fused compounds add to the growing catalog of RAS protein-protein inhibitors and show that building a chem. series by crossing over two chem. series is a strategy to create RAS-binding small mols.

The non-viral gene vector properties of a protein-like polymer, the α,β-poly(N-2-hydroxyethyl)-,-aspartamide (PHEA) were investigated after its derivatization with 3-(carboxypropyl)trimethyl-ammonium chloride (CPTA) as mol. bearing cationic groups, in order to obtain stable polycations able to condense DNA. PHEA was firstly functionalized with hydrazide pendant groups by reaction with hydrazine monohydrate (HYD), obtaining the polyhydrazide α,β-poly(N-2-hydroxyethyl/carbazate)-,-aspartamide (PHEA-HYD). In this paper we reported that polymer functionalization degree can be easily modulated by varying reaction conditions, so allowing us to produce two PHEA derivatives at different molar percentage of hydrazide groups. Subsequently, condensation reaction of PHEA-HYD copolymers with CPTA yielded α,β-poly(N-2-hydroxyethyl)-N-carbazate[N’-(3-trimethylammonium chloride)propylhydrazide]-,-aspartamide (PHEA-HYD-CPTA) polycation derivatives In vitro studies were carried out to evaluate polycations ability to complex DNA and to protect it from nuclease degradation Obtained results demonstrated the good efficiency of our new PHEA-polycations derivatives, PHEA-HYD-CPTA, to complex and condense genomic material even at very low polycation/DNA weight ratio.

The properties as non viral gene vector of a protein-like polymer, the α,β-poly(N-2-hydroxyethyl)-D,L-aspartamide (PHEA) were exploited after its derivatization with 3-(carboxypropyl)trimethyl-ammonium chloride (CPTA) as mol. bearing a cationic group, in order to obtain stable polycations able to condense DNA. PHEA was firstly functionalized with aminic pendant groups by reaction with ethylenediamine (EDA) obtaining the α,β-poly(N-2-hydroxyethyl)(2-aminoethylcarbamate)-D,L-aspartamide (PHEA-EDA) copolymer. We demonstrated that polymer functionalization degree is easily modulable by varying reaction conditions, so allowing to produce two PHEA-EDA derivatives at different molar percentage of amine groups. Subsequently, the condensation reaction of PHEA-EDA copolymers with CPTA yielded α,β-poly(N-2-hydroxyethyl)(2-[3-(trimethylammonium chloride)propylamide]-amidoethylcarbamate)-D,L-aspartamide (PHEA-EDA-CPTA) polycation derivatives In vitro studies were carried out to evaluate polycations ability to complex DNA and to protect it from nuclease degradation Obtained results demonstrated the good ability of our new PHEA polycationic derivatives, PHEA-EDA-CPTA, to complex and condense genomic material, neutralizing its anionic charge even at very low polycation/DNA weight ratio. Finally, PHEA-EDA-CPTA polycations were characterized by in vitro cytotoxicity studies to evaluate their effects on the viability of HuH-6 human hepatocellular carcinoma cells by MTS assay. No cytotoxicity was evidenced by both polycationic derivatives after 48 h of incubation at all tested concentrations

Cavallaro, Gennara published the artcileReversibly stable thiopolyplexes for intracellular delivery of genes, Application of 3-Carboxy-N,N,N-trimethylpropan-1-aminium chloride, the publication is Journal of Controlled Release (2006), 115(3), 322-334, database is CAplus and MEDLINE.

Novel polyaspartamide non-viral carriers for gene therapy were synthesized by introducing, on the same polymer backbone, pos. charged groups, for electrostatic interactions with DNA, and thiol groups for the formation of disulfide bridges between polymer chains. The introduction of thiols was aimed to have a vector with low redox potential sensitivity: disulfide crosslinking in fact, being stable in extracellular environment, allowed either to have stable complexes in plasma, that can protect DNA from metabolism, or to be reduced inside the cell, where the excess of glutathion in reduced form maintains a low redox potential. The consequent destabilization of the complex after disulfide cleavage can release DNA selectively inside the cells. α,β-poly(N-2-hydroxyethyl)-D,L-aspartamide (PHEA) was used as starting polymer being a highly water-soluble synthetic polymer, already proposed with success as therapeutic carrier by our group. In this study, PHEA was firstly functionalized with ethylendiamine, obtaining a well defined copolymer with pendant primary amine groups (PHEA-EDA), to which N-succinimidyl 3-(2-pyridyldithio) propionate (SPDP) and 3-(carboxypropyl)trimethyl-ammonium chloride (CPTA) were linked in two subsequent steps, allowing the introduction of thiol and cationic groups resp. Finally DTT treatment lead to the final PHEA-EDA-SH-CPTA thiopolycation, named PESC. The present work describes the synthesis and characterization of the thiopolycation PESC. ¹H NMR spectroscopy detected the derivatization molar degrees in SPDP and CPTA; the formation of DNA complexes (thiopolyplexes), their stability in the presence of polyanions and the ability to release DNA under reductive conditions were studied by agarose gel electrophoresis. DNase II degradation study was carried out to detect the ability of thiopolyplex to stabilize DNA towards enzymic metabolism Thiopolyplexes were then characterized by Dynamic Light Scattering (DLS) and Zeta Potential anal. Finally, in vitro toxicity profile (MTT) and gene transfer efficiency (Luciferase assay) were carried out to evaluate thiopolyplex biocompatibility, safety and efficacy to be used as gene delivery system.
