Due to the fact that tyrosinase is responsible for biosynthesis and regulation of melanins and browning food products, tyrosinase inhibitors can be favorable agents in cosmetics and medicinal industries. A series of novel 2-hydroxy-4-methoxybenzohydrazide were designed, synthesized, and their new application as tyrosinase inhibitors was also disclosed. Based on in vitro tyrosinase inhibitory assay, 4d as the strongest inhibitor of tyrosinase with an IC50 value of 7.57 mu M showed approximately 2.5-fold better inhibition than kojic acid as positive control followed by two compounds 4b (IC50 = 8.19 +/- 0.25 mu M) and 4j (IC50 = 8.92 +/- 0.016) which displayed preferable tyrosinase inhibitory activity. Detailed investigations on the mechanism of action of the 4d reported mix type of inhibition. More importantly, molecular modeling assessments proposed the ability of 4d for potential interaction with Cu (metal)-His (residue) within tyrosinase active site. Overall, 4d is a promising candidate for the development of anti-tyrosinase agents.

Histaminium tetrachlorozincate nanoparticles are prepared, characterized and applied as an effective and recoverable photocatalyst in the one-pot, green and multi-component synthesis of various chromenes by the reaction of dimedone and/or 1,3-cyclohexanedione, arylaldehyde and 4-hydroxycoumarin in high yields under solventless conditions at ambient temperature. This new catalyst is characterized by FT-IR, XRD, EDX, NMR, SEM and TEM techniques. The incorporation of histaminium ions into the framework of ZnCl42- significantly affected the photocatalytic activity of tetrachlorozincate such that good reusability and recyclability are attained. Moreover, reactive species such as O-2(-) and hydroxyl radicals have proved to be active species in the presented photocatalytic reaction. In addition, the hot filtration test confirms enough stability of the photocatalyst and no significant leaching and destruction of the framework in the course of the reaction. The major advantages of the presented methodology include easy work-up, cost effectiveness, nontoxic nature, broad substrate scope, 100% atom economy, ease of separation, and environment friendly reaction conditions. Finally, the catalyst could be reused many times without significant loss of activity.

Higher cocrystal synthesis depends acutely on a knowledge of supramolecular synthons. We report three synthetic approaches towards ternary halogen bonded cocrystals that illustrate specificity and generality. Electrophilicity/nucleophilicity differences are needed among alternative sites of halogen bond formation. The two halogen bonds AB and BC in a halogen bonded ternary cocrystal ABC need to be of different strength. Interaction mimicry of hydrogen bonds by halogen bonds is a viable approach towards ternaries as illustrated with the pyrene structure. Finally, the crystal engineer should well be able to anticipate halogen bonds that are stronger than hydrogen bonds.

The preparation of metal nanocomposite catalysts with MOFs as precursors has attracted extensive attention, as the design and preparation of catalysts by this method could maximize the advantages of the precursors and ensure the stability of the catalysts as much as possible. Here, a benzimidazole-modified Cu/Co bimetal-MOF as a precursor was used to synthesize a Cu-nanowire@Quasi-MOF material via a simple and low-cost thermal decomposition strategy for the first time. Experimental evaluation suggested that the Co-MOF part in Cu/Co bimetal-MOF was a morphology retainer, and the special channel composition of the Quasi-MOF played a space-confined role in the formation of the unique Cu-nanowires. Based on the detailed investigation, a possible formation mechanism was proposed. Furthermore, Cu-nanowire@Quasi-MOF exhibited excellent catalytic performance and good stability in the selective oxidation of benzyl alcohol in air. This study demonstrated that using MOFs as a precursor, by adjusting the calcination temperature and adding heteroatoms, can control the morphology of metal nanoparticles (MNPs) in MOF derivatives, reduce agglomeration and enhance catalytic activity, which will be a promising approach to in situ preparation of complex metal nanocomposites.

Stachyodin A, possessing a unique spirotetrahydrofuran ring system, was isolated from the roots of Indigofera stachyodes in 2018. The first total synthesis of racemic stachyodin A was accomplished in 14 steps. The efficient stereoselective synthetic route involved one-pot Suzuki coupling and stereocontrolled epoxidation followed by reductive opening and spirocyclization.

Organophosphorus flame retardants are stable toxic compounds used in nearly all durable plastic products and are considered major emerging pollutants. The phosphotriesterase from Sphingobium sp. TCM1 (Sb-PTE) is one of the few enzymes known to be able to hydrolyze organophosphorus flame retardants such as triphenyl phosphate and tris(2-chloroethyl) phosphate. The effectiveness of Sb-PTE for the hydrolysis of these organophosphates appears to arise from its ability to hydrolyze unactivated alkyl and phenolic esters from the central phosphorus core. How Sb-PTE is able to catalyze the hydrolysis of the unactivated substituents is not known. To interrogate the catalytic hydrolysis mechanism of Sb-PTE, the pH dependence of the reaction and the effects of changing the solvent viscosity were determined. These experiments were complemented by measurement of the primary and secondary 18-oxygen isotope effects on substrate hydrolysis and a determination of the effects of changing the pK(a) of the leaving group on the magnitude of the rate constants for hydrolysis. Collectively, the results indicated that a single group must be ionized for nucleophilic attack and that a separate general acid is not involved in protonation of the leaving group. The Bronsted analysis and the heavy atom kinetic isotope effects are consistent with an early associative transition state with subsequent proton transfers not being rate limiting. A novel binding mode of the substrate to the binuclear metal center and a catalytic mechanism are proposed to explain the unusual ability of Sb-PTE to hydrolyze unactivated esters from a wide range of organophosphate substrates.

Product Details of 100-51-6. I found the field of Polymer Science very interesting. Saw the article Mechanistic Insight into the Ring-Opening Polymerization of epsilon-Caprolactone and L-Lactide Using Ketiminate-Ligated Aluminum Catalysts published in 2019.0, Reprint Addresses Lin, YF (corresponding author), Kaohsiung Med Univ, Dept Fragrance & Cosmet Sci, Kaohsiung 80708, Taiwan.; Lin, YF (corresponding author), Kaohsiung Med Univ, Dept Med & Appl Chem, Kaohsiung 80708, Taiwan..

The reactivity and the reaction conditions of the ring-opening polymerization of epsilon-caprolactone (epsilon-CL) and L-lactide (LA) initiated by aluminum ketiminate complexes have been shown differently. Herein, we account for the observation by studying the mechanisms on the basis of density functional theory (DFT) calculations. The calculations show that the ring-opening polymerization of epsilon-CL and LA are rate-determined by the benzoxide insertion and the C-O bond cleavage step, respectively. Theoretical computations suggest that the reaction temperature of L-LA polymerization should be higher than that of epsilon-CL one, in agreement with the experimental data. To provide a reasonable interpretation of the experimental results and to give an insight into the catalyst design, the influence of the electronic, steric, and thermal effects on the polymerization behaviors will be also discussed in this study.

Zinc oxide (ZnO) prepared by chemical vapor deposition was combined with different amounts of carbon nanofibers (CNF) to obtain hybrid materials, which were thoroughly characterized using several techniques. The photocatalytic performance was evaluated towards the photocatalytic synthesis of vanillin (VAD) starting from vanillyl alcohol (VA). The incorporation of the carbon phase in ZnO (from 5% to 20% wt.) was found to increase the surface area and the photocatalytic performance of the materials. The latter was attributed to the efficient separation of charge carriers generated on the optical semiconductor. With the best performing material, the one containing 10% of CNF, the selectivity of the synthesis towards vanillin generation was increased by a factor of 2.5 compared to previous studies, with the additional advantage of carrying the reaction in aqueous medium. The same photocatalyst was successfully applied to the selective synthesis of other aromatic aldehydes, namely anisaldehyde, piperonal, and benzaldehyde. A relationship between the efficiency of the photocatalytic oxidation of the alcohols and the activating nature of their aromatic ring substituents was proposed.
