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.

A new methodology for the synthesis of alpha-diketones was reported via a one-pot cascade process from aldehydes and ketones catalyzed by a bifunctional iron nanocomposite using H2O2 as a green oxidant in water. The one-pot strategy showed excellent catalytic stability, comprehensive suitability of substrates and important practical utility for directly synthesizing biologically active and medicinally valuable N-heterocycles via an intermittent process.

New approaches to the synthesis of 4,7-dichloro-1,10-phenanthrolines and their corresponding 9H-carbazol-9-yl-, 10H-phenothiazin-10-yl- and pyrrolidin-1-yl derivatives were developed. Their properties have been characterized by a combination of several techniques: MS, HRMS, GC-MS, electronic absorption spectroscopy and multinuclear NMR in both solution and solid state including N-15 CP/MAS NMR. The structures of 5-fluoro-2,9-dimethyl-4,7-di(pyrrolidin-1-yl)-1,10-phenanthroline (5d), 4,7-di(9H-carbazol-9-yl)-9-oxo-9,10-dihydro-1,10-phenanthroline-5-carbonitrile (6a) and 4,7-di(10H-phenothiazin-10-yl)-1,10-phenanthroline-5-carbonitrile (6b) were determined by single-crystal X-ray diffraction measurements. The nucleophilic substitutions of hydrogen followed by oxidation produced compounds 6a and 6b. The electrochemical properties of selected 1,10-phenanthrolines were investigated using cyclic voltammetry and compared with commercially available reference 1,10-phenanthrolin-5-amine (5l). The spatial distribution of frontier molecular orbitals of the selected compounds has been calculated by density functional theory (DFT). It was shown that potentials of reduction and oxidation were in consistence with the level of HOMO and LUMO energies.

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

Inspired by the synergistic effects of hetero-aromatic scaffolds on curcumin, a novel array of pyrazoline substituted curcumin analogs was designed. Multi-scale computational studies were carried out to target the proposed analogs on human kinase beta (IKK-beta), a potential anti-cancer target. In molecular docking analysis, all the eleven molecules were observed to bind the target site and 4-bromo-4′-chloro analog displayed three hydrogen bond interactions with a docking score of -11.534 kcal/mol higher than parent molecule, curcumin (docking score = -7.12 kcal/mol) as the propellant shaped of analogs aided in proper binding with Kinase Domain binding pocket. The molecular dynamics and simulations studies revealed that the stable complexes of lead molecule were developed as the minimal deviations per residue of protein found within the range of 0.11 to 0.92 angstrom. The proposed compounds were synthesized, characterized and biologically evaluated against human cervical cancer cell line, HeLa, using standard MTT cell assay. Bio-evaluation studies exhibited superior cytotoxic profile for many analogs as Chloro bromo analog with IC50 value (8.7 mu g/mL) exhibited fivefolds improvement in the potency in comparison to curcumin (IC50 = 42.4 mu g/mL) but was less potent than the standard drug, paclitaxel (IC50 = 0.008 mu g/mL). The apoptotic effect was evaluated in the terms of caspase-3 enzyme cleavage and exhibited 70.5% of apoptosis significantly (p < 0.05) higher than 19.9% induced by curcumin. In short, 4-bromo-4'-chloro analog was the potent cytotoxic agent in this structural class and must be evaluated further under a set of stringent parameters for transforming in to a clinically viable therapeutic molecule.

The most red-shifted hemithioindigo photoswitches have been identified through systematic introduction of aryl units to a parent pyrrole hemithioindigo photoswitch. Increasing the size of the 5′-aryl substituent is ineffective at producing further redshifted chromophores. A second generation of 3′,5′-diarylated photoswitches which possess increased tunability is reported. Experimental and computational evidence indicates the 4′ position is electronically isolated from the bulk of the conjugated system. (C) 2019 Elsevier Ltd. All rights reserved.

Polymeric carbon nitride materials have been used in numerous light-to-energy conversion applications ranging from photocatalysis to optoelectronics. For a new application and modelling, we first refined the crystal structure of potassium poly(heptazine imide) (K-PHI)-a benchmark carbon nitride material in photocatalysis-by means of X-ray powder diffraction and transmission electron microscopy. Using the crystal structure of K-PHI, periodic DFT calculations were performed to calculate the density-of-states (DOS) and localize intra band states (IBS). IBS were found to be responsible for the enhanced K-PHI absorption in the near IR region, to serve as electron traps, and to be useful in energy transfer reactions. Once excited with visible light, carbon nitrides, in addition to the direct recombination, can also undergo singlet-triplet intersystem crossing. We utilized the K-PHI centered triplet excited states to trigger a cascade of energy transfer reactions and, in turn, to sensitize, for example, singlet oxygen (O-1(2)) as a starting point to synthesis up to 25 different N-rich heterocycles.

A one-pot route to 2-alkyl and 2-aryl-4H-benzo[d][1,3]oxazin-4-ones (also known as 4H-3,1-benzoxazin-4-ones) has been developed and studied. The method involves the reaction of aryl-substituted anthranilic acids with orthoesters in ethanol catalyzed by acetic acid. Additionally, we have also investigated the reaction under microwave conditions. Not all of the substrates were successful in yielding the target heterocycles as some of the reactions failed to undergo the final elimination. This process led to the isolation of (+/-)-2-alkyl/aryl-2-ethoxy-1,2-dihydro-4H-benzo[d][1,3]oxazin-4-ones. The formation of the dihydro analogs correlated with the electron density on the aromatic ring: Electron-donating groups favored the 4H- benzo[d][1,3]oxazin-4-ones, while electron-withdrawing groups tended to favor the dihydro product. Substituting a pyridine ring for the benzene ring in the substrate acid suppressed the reaction.

With raising prevalence of obesity, the regulation of human body fat is increasingly relevant. The modulation of fatty acid uptake by enterocytes represents a promising target for body weight maintenance. Recent results demonstrated that the trigeminal active compounds capsaicin, nonivamide, and trans-pellitorine dose-dependently reduce fatty acid uptake in differentiated Caco-2 cells as a model for the intestinal barrier. However, non-pungent alternatives have not been investigated and structural determinants for the modulation of intestinal fatty acid uptake have not been identified so far. Thus, based on the previous results, we synthesized 23 homovanillic acid esters in addition to the naturally occurring capsiate and screened them for their potential to reduce intestinal fatty acid uptake using the fluorescent fatty acid analog Bodipy-C12 in differentiated Caco-2 cells as an enterocyte model. Whereas pre-incubation with 100 mu M capsiate did not change fatty acid uptake by Caco-2 enterocytes, a maximum inhibition of -47% was reached using 100 mu M 1-methylpentyl-2-(4-hydroxy-3-methoxy-phenyl)acetate. Structural analysis of the 24 structural analogues tested in the present study revealed that a branched fatty acid side chain, independent of the chain length, is one of the most important structural motifs associated with inhibition of fatty acid uptake in Caco-2 enterocytes. The results of the present study may serve as an important basis for designing potent dietary inhibitors of fatty acid uptake.

The [4+2] cycloaddition reaction of the (dimesitylphosphino) cyclopentadienes 5a,b with N-phenyl-maleimide gave the norbornene derivative 9. Its reduction with LiAlH4 produced the N-phenyl-pyrrolidino-annulated system 10. Treatment with Piers’ borane gave the respective P/B FLP 12 as the major product, which cleaved dihydrogen under mild conditions to yield the phosphonium/hydrido borate product 14. Reaction of the phosphino-norbornene 10 with 2 M equiv. of Piers’ borane [HB(C6F5)(2)] followed by exposure to dihydrogen eventually gave the HB(C6F5)(2) adduct 15. This served as a catalyst for the hydrogenation of a series of chalcone derivatives. The system requires a pre-activation period before becoming active for the conjugated enone hydrogenation.
