Dong, Huan published the artcileSynthesis and properties of tetraphenylethylene derivatived diarylethene with photochromism and aggregation-induced emission, HPLC of Formula: 219537-97-0, the publication is Dyes and Pigments (2017), 118-128, database is CAplus.

A series of new diarylethene compounds with both photochromism and aggregation-induced emission have been synthesized by connecting tetraphenylethene and triphenylethene to the bisthienylethene. All the four compounds exhibit good photochromism upon irradiation with alternative UV and visible light. And they are all provided with aggregation-induced emission properties in THF solution with different fraction of water, non-emissive in the pure THF solution but yellowish green fluorescence in the aggregate or solid state. Furthermore, the compounds connecting tetraphenylethene to the bisthienylethene were found to exhibit the stronger fluorescence emission in the aggregate or solid state than the ones connecting triphenylethene to the bisthienylethene.

Wang, Huaimin published the artcileEnzyme-Catalyzed Formation of Supramolecular Hydrogels as Promising Vaccine Adjuvants, Application In Synthesis of 42074-68-0, the publication is Advanced Functional Materials (2016), 26(11), 1822-1829, database is CAplus.

Promising vaccine adjuvants of self-assembling peptide hydrogels for protein ovalbumin (OVA) are introduced in this study. The hydrogels are formed by the enzyme of phosphatase, and the vaccine adjuvant potency of both L– and D-peptide hydrogels is evaluated. The results indicate that, compared with the clin. used alum adjuvant, both L– and D-peptide hydrogels can increase the IgG production of OVA for about 1.3 and 3.8 times, resp. Both gels can enhance antigen uptake and induce dendritic cell maturation, and promote and prolong accumulation of antigen in lymph node, as well as evoke germinal center formation. However, the D-peptide hydrogel with OVA exhibits a slightly more efficient accumulation of OVA in the lymph nodes and seems preventing tumor growth more significantly than its L-counterpart. With the good biocompatibility and degradability of peptide hydrogels, the hydrogels described in this study have big potential for the production of protein vaccines for immunotherapy against different diseases.

Luong, Hoa published the artcileImprovement in the One-Carbon Chain Extension of Esters with Dimethylsulfoxonium Methylide, HPLC of Formula: 5034-06-0, the publication is European Journal of Organic Chemistry (2013), 2013(20), 4238-4241, database is CAplus.

A recent report suggests that the reaction of dimethylsulfoxonium methylide with esters does not produce a chain-extended sulfur ylide as previously reported, but rather affords the corresponding carboxylate salt. We have investigated this assertion by using a combination of ab initio MO calculations, spiking studies, and isotopic labeling. The formation of carboxylate is unambiguously demonstrated to arise through hydrolysis involving adventitious water, principally derived from moisture in com. trimethylsulfoxonium chloride. Careful vacuum drying of this reagent diminishes the competing hydrolytic pathway resulting in higher yields for the chain-extension reaction than previously reported.

Hrdina, R. published the artcileIron complexes of reactive azo dyes, Related Products of chlorides-buliding-blocks, the publication is Advances in Colour Science and Technology (2004), 7(1), 6-17, database is CAplus.

A set of reactive mordant azo dyes was prepared by diazotization of aromatic amines and their subsequent coupling reaction with secondary components. The reactive dyes thus formed contained 2-sulfatoethylsulfonyl (-SO₂CH₂CH₂OSO₃Na), N-methyl-N-carboxymethyl-2-aminoethylsulfonyl (-SO₂CH₂CH₂NMeCH₂CO₂H) and 2,3-dibromopropionamidyl (-NHCOCHBrCH₂Br) reactive groups capable of liberating reactive vinyl groups in the application dyebath. Neg.-ion electrospray ionization mass spectrometry, UV/visible spectroscopy, and elemental anal. confirmed the structure of the prepared dyes. Dyed wool fabric samples (combination of acid and reactive dyeing conditions) were treated (mordanted) with iron salts (FeCl₂, FeCl₃) and a comparison chromium salt (CrF₃). The iron mordant dyeing showed acceptable wash fastness and light fastness comparable with chromium complexed dyes.

Ruzi, Rehanguli published the artcileDeoxygenative Arylation of Carboxylic Acids by Aryl Migration, Recommanded Product: Coumarin-6-sulfonyl chloride, the publication is Chemistry – A European Journal (2019), 25(55), 12724-12729, database is CAplus and MEDLINE.

An unprecedented deoxygenative arylation of aromatic carboxylic acids was achieved, allowing the construction of an enhanced library of unsym. diaryl ketones. The synergistic photoredox catalysis and phosphoranyl radical chem. allows for precise cleavage of a stronger C-O bond and formation of a weaker C-C bond by 1,5-aryl migration under mild reaction conditions. This new protocol was independent of substrate redox-potential, electronic, and substituent effects. It afforded a general and promising access to 60 examples of synthetically versatile o-amino and o-hydroxy diaryl ketones under redox-neutral conditions. Furthermore, it also brings one concise route to the total synthesis of quinolone alkaloid, (±)-yaequinolone A2, and a viridicatin derivative in satisfying yields.

Zhang, Sheng published the artcileA Highly Selective and Potent PTP-MEG2 Inhibitor with Therapeutic Potential for Type 2 Diabetes, Product Details of C8H7ClO3, the publication is Journal of the American Chemical Society (2012), 134(43), 18116-18124, database is CAplus and MEDLINE.

Protein tyrosine phosphatases (PTPs) constitute a large family of signaling enzymes that control the cellular levels of protein tyrosine phosphorylation. A detailed understanding of PTP functions in normal physiol. and in pathogenic conditions has been hampered by the absence of PTP-specific, cell-permeable small-mol. agents. We present a stepwise focused library approach that transforms a weak and general non-hydrolyzable pTyr mimetic (F₂Pmp, phosphonodifluoromethyl phenylalanine) into a highly potent and selective inhibitor of PTP-MEG2, an antagonist of hepatic insulin signaling. The crystal structures of the PTP-MEG2-inhibitor complexes provide direct evidence that potent and selective PTP inhibitors can be obtained by introducing mol. diversity into the F₂Pmp scaffold to engage both the active site and unique nearby peripheral binding pockets. Importantly, the PTP-MEG2 inhibitor possesses highly efficacious cellular activity and is capable of augmenting insulin signaling and improving insulin sensitivity and glucose homeostasis in diet-induced obese mice. The results indicate that F₂Pmp can be converted into highly potent and selective PTP inhibitory agents with excellent in vivo efficacy. Given the general nature of the approach, this strategy should be applicable to other members of the PTP superfamily.

Yu, Fei published the artcilePhotostimulus-Responsive Large-Area Two-Dimensional Covalent Organic Framework Films, Quality Control of 219537-97-0, the publication is Angewandte Chemie, International Edition (2019), 58(45), 16101-16104, database is CAplus and MEDLINE.

Using an external stimulus to modulate the electronic structure of covalent organic frameworks (COFs) is very important because such a response will endow them with addnl. functions. A two-dimensional (2D) COF, constructed from a photo-responsive unit (1,2-bis(5-formyl-2-methylthien-3-yl)cyclopentene), can reversibly switch its elec. conductivity 200 times from low state (the open form) to high state (the closed form) upon irradiation with UV light and reversible with visible light. This reversible phenomenon can be monitored through a circuit containing a light-emitting diode (LED). Photoinduced ring-closing/opening reactions do not destroy the integrity of the frameworks, and both processes follow logarithmic carrier generation with time. Moreover, the correlation between COFs electronic properties and changes in photoinduced kinetics and absorption curves has been demonstrated.

An efficient one-pot synthesis of multisubstituted 9,10-dihydrophenanthrenes from easily available 2-arylazaarenes and cyclohexadienone-tethered terminal alkynes (1,6-enynes) has been successfully achieved. This domino reaction proceeded smoothly through Cp*Rh(III)-catalyzed C-H activation, direct protonation of alkenyl-Rh intermediates, intramol. Diels-Alder reaction, alkene isomerization, subsequent ring-opening aromatization, and acetylation. This strategy was pot-economical and tolerated a wide range of functional groups. Moreover, the potent anticancer activities against HepG2 cells were observed for these artificial 9,10-dihydrophenanthrene derivatives

Tan, Yun-Xuan published the artcileAn unconventional trans-exo-selective cyclization of alkyne-tethered cyclohexadienones initiated by rhodium(III)-catalyzed C-H activation via insertion relay, Application In Synthesis of 637-07-0, the publication is CCS Chemistry (2021), 3(5), 1582-1595, database is CAplus.

Different from the established trans-endo-selective cyclization of alkyne-tethered electrophiles that involve an E/Z isomerization process, herein, the authors present a novel strategy to allow trans-exo-selective arylative cyclization of 1,6-enynes. Through initiation of rhodium(III)-catalyzed C-H activation, a diverse range of N-heterocyclic directing groups, including pyridine, pyrazole, imidazo[1,2-a] pyridine, benzoxazole, benzothiazole, and purine, was feasible for the cascade transformation, exhibiting high efficiency (up to 92% yield), broad substrate scope, and excellent functional group compatibility. Moreover, the modification of natural products and pharmaceutical compounds was also demonstrated to showcase its synthetic utility. Based on d. functional theory (DFT) calculations, a key three-membered ring intermediate through the insertion relay, rather than the direct E/Z isomerization of alkenyl rhodium species, controlled the stereochem. outcome for this trans-exo-selective cyclization. The subsequent ring-opening protonation of the more favored rotamer led to exclusive trans-exo-selectivity.
