Enones 1, are examples of available and attractive building block which already has the polyfluoroalkyl group in blocks skeleton and their functionalization is an actual and perspective approach for the synthesis of more functionalized molecules. This approach led us to new polyfluoroalkyl containing trioxabicyclo[3.3.1]nona-3,7-diene-4,8-dicarboxylates with four trifluoromethyl or two trifluoromethyl and two difluoromethyl groups in moderate yields (up to 68%). These compounds are perspective as synthetic intermediates for preparation of new polyfluoromethyl containing heterocycles as well as their interaction into macrocycles system like crown ethers.

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

In an attempt to synthesise new tyrosinase inhibitors, we designed and synthesised a series of chalcone-hydroxypyridinone hybrids as potential tyrosinase inhibitors adopting strategic modifications of kojic acid. All the newly synthesised compounds were characterised by NMR and mass spectrometry. Initial screening of the target compounds demonstrated that compounds1a,1d, and1nhad relatively strong inhibitory activities against tyrosinase monophenolase, with IC(50)values of 3.07 +/- 0.85, 2.25 +/- 0.8 and 2.75 +/- 1.19 mu M, respectively. The inhibitory activity against monophenolase was 6- to 8-fold higher than that of kojic acid. Compounds1a,1d, and1nalso showed inhibition of diphenolase, with IC(50)values of 17.05 +/- 0.07, 11.70 +/- 0.03 and 19.3 +/- 0.28 mu M, respectively. The inhibition kinetics of diphenolase indicates that compounds1aand1dinduce reversible inhibition on tyrosinase. Finally, we found that copper coordination should be one of the important inhibitory mechanism of these compounds in tyrosinase.

Polyaniline coated on particles of celite is used as support to load palladium catalyst. This heterogenized Celite center dot PANI center dot Pd system, is used as an efficient catalyst for chemoselective hydrogenation reactions. The catalyst is characterized by usual spectral, analytical techniques and studied for hydrogenation reactions at ambient conditions. The mild reaction conditions allow the control over the reactions and excellent selectivity is achieved in number of conversions. Hydrogenation of a carbon-carbon double bond was favored over other polar pi-bond systems, while labile functional groups such as benzyl ether, benzyl esters, cyano, nitro and halogen remained unaffected. Primary amines were converted to N,N-dimethyl amines with formaldehyde, the double bond of coumarin was selectively hydrogenated without opening of the lactone functionality.

This Letter describes the chemical optimization of a new series of muscarinic acetylcholine receptor subtype 1 (MO positive allosteric modulators (PAMs) based on novel tricyclic triazolo- and imidazopyridine lactam cores, devoid of M-1 agonism, e.g., no M-1 ago-PAM activity, in high expressing recombinant cell lines. While all the new tricyclic congeners afforded excellent rat pharmacokinetic (PK) properties (CLp < 8 mL/min/kg and t(1/2) > 5 h), regioisomeric triazolopyridine analogues were uniformly not CNS penetrant (K-p < 0.05), despite a lack of hydrogen bond donors. However, removal of a single nitrogen atom to afford imidazopyridine derivatives proved to retain the excellent rat PK and provide high CNS penetration (K-p > 2), despite inclusion of a basic nitrogen. Moreover, 24c was devoid of M-1 agonism in high expressing recombinant cell lines and did not induce cholinergic seizures in vivo in mice. Interestingly, all of the new M-1 PAMs across the diverse tricyclic heterocyclic cores possessed equivalent CNS MPO scores (>4.5), highlighting the value of both medicinal chemist’s eye and experimental data, e.g., not sole reliance (or decision bias) on in silico calculated properties, for parameters as complex as CNS penetration.

A group of novel 1,4-bis(3,5-dialkyl-4H-1,2,4-triazol-4-yl)bencene and 5-aryltriaz- 1-en-1-yl-1-phenyl-1H-pyrazole-4-carbonitrile derivatives have been successfully synthesized and characterized by spectroscopic analyses. The triazenes were obtained in moderate yield by a coupling reaction between 5-aminopyrazol-4-carbonitrile and aryl diazonium chlorides, and their structures were confirmed by detecting the CN functional group in both IR and C-13 NMR spectra. Conversely, the novel 1,4-bis(3,5-dialkyl-4H-1,2,4-triazol-4-yl)benzene derivatives were obtained using a previously unreported and facile pathway starting with p-phenylenediamine with selected triethyl orthoalkylates and then hydrazine monohydrate, followed by refluxing in triethyl orthoalkylates. The structure of the methyl derivative was confirmed by X-ray analysis. The synthesized compounds were tested and evaluated as antimicrobial agents.

Among them, the compound with most potential, 22i, exhibited excellent anti-tumor activity against A549, MCF-7 and HeLa cancer cell lines with IC50 values of 0.83 +/- 0.07 mu M, 0.15 +/- 0.08 mu M and 2.85 +/- 0.74 mu M, respectively, and it also possessed superior c-Met kinase inhibition ability at the nanomolar level (IC50 = 48 nM). Moreover, dose-dependent experiments, AO fluorescence staining, cell cycle assay, Annexin V-FITC/PI staining and docking studies were carried out in this study. The results demonstrated that compound 22i could be a potential c-Met kinase inhibitor.

Chalcones, as a large group of organic compounds, are widely implemented in various types of anticancer therapeutics. These plant metabolites are present in fruits, vegetables, spices, and have anti-tumor, anti-inflammation, immunomodulation, antibacterial and anti-oxidative activities, as well as many other pharmacological and biological effects. The aim of the present study was to investigate cytotoxic effects, type of cell death and mechanism of action of the newly synthesized vanillin based chalcone analogs, (CH1) and (CH2) on human colon cancer HCT-116 and noncancerous (control) MRC-5 cell lines. In order to compare the effects of vanillin based chalcone analogs on investigated cell lines, as reference substances cisplatin (cisPt) and dehydrozingerone (DHZ) were used. Investigation of antitumor effect of chalcone analogs on HCT-116 cells was carried out by three methods MTT assay, flow cytometry and immunofluorescence analysis. The result of our investigation indicated that newly synthesized vanillin based chalcone analogs expressed powerful antitumor effect on cancer cells (HCT-116 cell line), while their effect on healthy cells (MRC-5 cell line) was not statistically significant. Vanillin based chalcone analogs caused overexpression and activation of mitochondrial Bax protein and caspase-3 in HCT-116 cells, indicating that their mechanism of antitumor action was mediated through activation of the inner apoptotic pathway. These results indicate possible usefulness of CH1 and CH2 in antitumor therapy whether through its direct cytotoxic effect or as adjuvant therapy. Our results indicate possible usefulness of CH1 and CH2 vanillin based chalcone analogs in antitumor therapy.

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.
