Carbonyl-olefin metathesis and carbonyl-alkyne metathesis represent established reactivity modes between carbonyls, alkenes, and alkynes under Lewis and Bronsted acid catalysis. Recently, an interrupted carbonyl-olefin metathesis reaction has been reported that results in tetrahydrofluorenes via a distinct fragmentation of the reactive intermediate. We herein report the development of an analogous transformation interrupting the carbonyl-alkyne metathesis reaction path resulting in dihydrofluorene products relying on Lewis acidic superelectrophiles as active catalytic species.

Hsp90, as a key molecular chaperone, plays an important role in modulating the activity of many cell signaling proteins and is an attractive target for anticancer therapeutics. Herein, we report the discovery of N-pyridoyl-Delta(2)-pyrazoline analogs as novel Hsp90 inhibitors by integrated approaches of drug design, organic synthesis, cell biology, and qualitative proteomic analysis. Novel chemical compounds were designed and optimized in the adenosine triphosphate-binding site of Hsp90; lead optimized compounds were found to have significant interactions with Asp93 and other amino acids crucial for Hsp90 inhibition. The designed compounds were synthesized by a two-step procedure; different aromatic aldehydes were reacted with various acetophenones to form substituted 1,3-diphenyl-prop-2-enones (Ic-Io), which upon reaction with isonicotinic acid hydrazide in the presence of glacial acetic acid form N-pyridoyl-Delta(2)-pyrazoline compounds (PY1-PY13). Compounds PY3, PY2, and PY1 were identified as potential leads amongst the series, with promising anticancer activity against human breast cancer and melanoma cells, and the ability to inhibit Hsp90 similar to radicicol by drug-affinity responsive target stability proteomic analysis in a whole-cell assay.

The Name is Chalcone. Through research, I have a further understanding and discovery of 94-41-7.

Various phytochemicals have been reported to protect against oxidative stress. However, the mechanism underlying has not been systematically evaluated, which limited their application in disease treatment. Nuclear factor erythroid 2 – related factor 2 (Nrf2), a central transcription factor in oxidative stress response related to numerous diseases, is activated after dissociating from the cytoskeleton – anchored Kelch – like ECH – associated protein 1 (Keap1). The Keap1-Nrf2 protein-protein interaction has become an important drug target. This study was designed to clarify whether antioxidantive phytochemicals inhibit the Keap1-Nrf2 protein-protein interaction and activate the Nrf2-ARE signaling pathway efficiently. Molecular docking and 3D – QSAR were applied to evaluate the interaction effects between 178 antioxidant phytochemicals and the Nrf2 binding site in Keap1. The Nrf2 activation effect was tested on a H2O2 – induced oxidative – injured cell model. Results showed that the 178 phytochemicals could be divided into high – , medium – , and low – total -score groups depending on their binding affinity with Keap1, and the high total – score group consisted of 24 compounds with abundant oxygen or glycosides. Meanwhile, these compounds could bind with key amino acids in the structure of the Keap1 – Nrf2 interface. Compounds from high – total – score group show effective activation effects on Nrf2. In conclusion, phytochemicals showed high binding affinity with Keapi are promising new Nrf2 activators.

Efficient hydrogenation of electron-deficient internal olefins and alkynes access to saturate ketone with CH3OH as a single hydrogen donor under electrochemical conditions has been successfully developed. This hydrogenation strategy can be used to convert electron-deficient internal olefins and alkynes to saturate ketone under electrochemical conditions with exogenous-reductant and a metal catalyst. Mechanistic studies reveal that radical hydrogenation was involved in this transformation. Notably, various electron-deficient internal olefins and alkynes could be tolerated in such an electrochemical hydrogenation synthetic strategy and can be easily scaled up with good efficiency.

Bacterial lipopolysaccharides (LPS) are important bio-medical structures, playing a major role in the interaction with human immune systems. Their core regions, containing multiple units ofl-glycero-d-mannoheptoses (l,d-heptose), are highly conserved structurally (withO3 andO7 glycosidic bonds), making them an epitope of high interest for the potential development of new antibiotics and vaccines. Research in this field has always been restricted by the limited availability of the parentl,d-heptose as well as its biochemical epimeric precursord-glycero-d-mannoheptose (d,d-heptose). This problem of availability has recently been solved by us, through a rapid and efficient practical synthesis ofl,d-manno-heptose peracetate demonstrated at scale. Herein we report an optimized, technically simple and versatile synthetic strategy for the differentiation of both thel-glyceroandd-glycero-d-mannoheptose scaffolds. Our approach is based on an orthoester methodology for the differentiation of all three positions of the sugar core using aO6,O7-tetraisopropyl disiloxyl (TIPDS) protecting group for the exocyclic positions. Furthermore, the regioselective opening toward 7-OH acceptors (6O-FTIPDS ethers) differentiates the exocyclic diol which has been demonstrated with a broader set of substrates and for bothmanno-heptoses for the first time.

Pseudomonas aeruginosa is a biofilm-forming Gram-negative bacterium and a leading cause of life-threatening nosocomial infections. The polysaccharide synthesis locus (Psl) exopolysaccharide of P. aeruginosa is a key constituent of the defending bacterial biofilm layer and is a promising therapeutic target for resistant species. The Psl exopolysaccharide is built up from repeating pentasaccharide units which contain one alpha- and two beta-mannosidic linkages, and one l -rhamnose and one d -glucose moieties. The preparation of this pentasaccharide was first described by Boons et al. in a 34-step synthesis. Based on their work, we have developed a new and effective pathway for the synthesis of the repeating pentasaccharide unit of the Psl exopolysaccharide. We have succeeded in simplifying the synthesis of the l -rhamnose and the alpha-selective d -mannose building blocks. Furthermore, taking advantage of a chemoselective pre-activation-based beta-mannosylation, we directly prepare a thioglycoside disaccharide donor and use it in the next coupling reaction without further transformation. The pentasaccharide, in the form of a p -methoxyphenyl glycoside, is prepared in 26 steps, which is suitable for biological testing.

The heterogeneous heteropolyacid-catalyzed acetalization of glycerol with acetone was investigated under solvent-free conditions. In this work, the calcined Ta/W mixed addenda heteropolyacid catalyst ({H-20}-355) was employed as a solid acid catalyst and showed much higher activity than these soluble Keggin-type catalysts in the acetalization of glycerol with acetone due to its superacidity (H-0 =-12.95). Meanwhile, it showed high stability in catalytic recycles and extended for acetalization of glycerol with the other aldehydes and ketones. Based on the catalyst characterization by X-ray diffraction (XRD), scanning electron microscopy (SEM), P-31 NMR spectra, FT-IR spectra, pyridine-absorbed FT-IR, and Hammett acidity functions (H-0) by UV-vis spectroscopy, it was found that the acidic strength of the Ta/W mixed addenda heteropolyacid was highly dependent on the contents of crystalline water that could be tuned by calcination temperature. Notably, the solid superacid catalyst {H-20}355 was swollen by acetone, exhibiting an interesting pseudo-liquid behavior, which served as a microreactor and facilitated the reaction. Furthermore, after the acetalization reaction of glycerol with furfural (98% yield of acetal) on {H-20}-355 catalyst, the furan ring of the acetal products can be hydrogenated sequentially into dioxolane or dioxane with Pd/C catalyst under room temperature condition without the need of any isolation procedure.

The development of new techniques and materials that can separate ethylene from ethane is highly relevant in modern applications. Although adsorption-based separation techniques using metal-organic frameworks (MOFs) have gained increasing attention, the relatively low stability (especially water resistance) and unscalable synthesis of MOFs severely limit their application in real industrial scenarios. Addressing these challenges, we rationally designed and synthesized two new C2H6-selective MOF adsorbents (NKMOF-8-Br and -Me) with ultrahigh chemical and thermal stability, including water resistance. Attributed to the nonpolar/hydrophobic pore environments and appropriate pore apertures, the MOFs can capture C-2 hydrocarbon gases at ambient conditions even in high humidity. The single-crystal structures of gas@NKMOF-8 realized the direct visualization of adsorption sites of the gases. Both the single-crystal data and simulated data elucidate the mechanism of selective adsorption. Moreover, the NKMOF-8 possesses high C2H6 adsorption capacity and high selectivity, allowing for efficient C2H6/C2H4 separation, as verified by experimental breakthrough tests. Most importantly, NKMOF-8-Br and -Me can be scalably synthesized through stirring at room temperature in minutes, which confers them with great potential for industrial application. This work offers new adsorbents that can address major chemical industrial challenges and provides an in-depth understanding of the gas binding sites in a visual manner.
