In the last few years, essential oils (EOs) derived from plants have aroused great interest due to their well-known antimicrobial activity. Unfortunately, they present several limitations in their use, such as photosensitivity, temperature sensitivity, high volatility, and poor water solubility The encapsulation technique represents a good solution to these problems and ensures protection of the functional properties of essential oils. In this work, bergamot essential oil (BEO) and sweet orange essential oil (OEO) loaded-Eudragit RS 100 (EuRS100) nanoparticles (NPs) were prepared by using the nanopptn. technique. We obtained nanoparticles characterized by a mean diameter of 57 to 208 nm and a pos. surface charge (39 to 74 mV). The antibacterial activity of the obtained systems against Escherichia coli was in vitro investigated. We demonstrated that both orange and bergamot essential oils were successfully encapsulated and our nanoparticles have good antibacterial activity. Finally, in order to evaluate the potential applicability of OEONps to prolong fresh orange juice shelf-life, survival of E. coli during a storage period of one week at 25°C was investigated: Orange essential oil-loaded nanoparticles (OEONPs) have been able to prolong the orange juice shelf life.

Heng, Ya Gao; Wen, Li Peng; Pan, Pan Meng; Xue, Feng Feng; Jian, Qiang Li; Hui, Qiong Wu; Chang, Sheng Yan; Yang, Yang Xiong; Luo, Feng published the artcile< Lanthanide separation using size-selective crystallization of Ln-MOFs>, Formula: C14H8N2Na2O6, the main research area is size selective crystallization separation lanthanide olsalazine MOF; crystal structure lanthanide olsalazine MOF preparation.

Herein, the authors report an elaborate method, size-selective crystallization of Ln-MOFs, to isolate lanthanide (Ln) ions. Herein, 13 lanthanide ions, except for the radioactive Pm(III) ion and ytterbium, were separated by four types of Ln-MOFs: type I [La-Pr, Ln2(OLZ)(H2OLZ)(DMF)(H2O)2·2H2O], type II [Nd-Eu, Ln(OLZ)0.5(H2OLZ)0.5(DMF)(μ2-DMF)0.5], type III [Gd-Ho, Ln(OLZ)0.5(H2OLZ)0.5(DMF)(H2O)·H2O], and type IV [Er-Lu, Ln2(OLZ)(H2OLZ)(H2O)4 where OLZ = olsalazine]. Further systemic investigation also suggested the highly selective separation of lanthanide ions by this method.

Su, Lebin; Xie, Shimin; Dong, Jianyu; Liu, Feng; Yin, Shuang-Feng; Zhou, Yongbo published the artcile< Copper-Catalyzed Nitrogen Atom Transfer to Isoquinolines via C-N Triple Bond Cleavage and Three-Component Cyclization>, Name: (4-Ethynylphenyl)methanol, the main research area is bromoaryl ketone alkyne acetonitrile copper catalyst three component cyclization; isoquinoline preparation.

A copper(I)-catalyzed tandem reaction of 2-bromoaryl ketones, terminal alkynes, and CH3CN was developed, which combines N atom transfer and three-component [3 + 2 + 1] cyclization, and efficiently produces densely functionalized isoquinolines in a facile, highly selective, and general manner. In the reaction, the formation of aromatic C-N bonds along with the complete C-N triple bond cleavage was first realized; Cu(III)-acetylide species might serve as the intermediates, which allow highly selective 6-endo-dig cyclization.

Yan, Jing-Kun; Wu, Li-Xia; Qiao, Ze-Ru; Cai, Wu-Dan; Ma, Haile published the artcile< Effect of different drying methods on the product quality and bioactive polysaccharides of bitter gourd (Momordica charantia L.) slices>, Category: alcohols-buliding-blocks, the main research area is drying polysaccharide bitter gourd antioxidant antidiabetic; Bioactivity; Bitter gourd (Momordica charantia L.); Drying method; Physicochemical property; Polysaccharide.

In this study, three drying methods, namely, hot-air drying, freeze drying (FD), and IR radiation drying (ID), were applied to dry bitter gourd (Momordica charantia L.) slices. Results showed that the drying methods had significant influences on appearance, color, rehydration ratio, and microstructure of dried bitter gourd. FD provided high-quality dried bitter gourd products due to the uniform honeycomb network and less collapsed structure. Three water-soluble bitter gourd polysaccharides (BPS-H, BPS-F, and BPS-I) were obtained from the bitter gourd dried using the three drying methods. The three polysaccharides exhibited similar preliminary structural characteristics with different monosaccharide compositions and mol. weights BPS-I obtained from ID-dried bitter gourd had higher sugar and uronic acid contents than BPS-H and BPS-F. BPS-I exhibited stronger antioxidant activities and bile acid-binding capacity in vitro than BPS-H and BPS-F. Moreover, BPS-F and BPS-I showed significant α-amylase inhibitory activities in vitro.

Das, Joydip published the artcile< Identification of alcohol-binding site(s) in proteins using diazirine-based photoaffinity labeling and mass spectrometry>, HPLC of Formula: 25055-82-7, the main research area is protein alc binding site diazirine photoaffinity labeling mass spectrometry; alcoholism; azialcohol; diazirine; mass spectrometry; photoaffinity labeling.

Defining mol. targets of alc. and understanding the mol. mechanism of alc. actions are necessary to develop effective therapeutics for alc. use disorder (AUD). Here, we describe a detailed protocol for identifying alc.-binding site(s) in proteins using diazirine-based azialc. as photoaffinity labeling agents. Upon photoirradiation, azialc. photoincorporates into alc.-binding proteins. The stoichiometry and site of azialc. photoincorporation can be determined using high-resolution mass spectrometry. Identification of the alc.-binding residues in protein followed by measuring the biol. significance of these residues in regulating alc. action are important steps in characterizing the mol. targets of alc.

A magnetic asym. Salamo-based Zn complex (H2L = salen type di-Schiff bases)-supported on the surface of modified Fe3O4 (Fe3O4@H2L-Zn) as a new catalyst was designed and characterized via numerous anal. techniques such as FT-IR spectroscopy, XRD, EDS, ICP-AES, SEM, TEM, TGA and VSM. An efficient and sustainable synthetic protocol were presented for the synthesis of silyl ether substructures via the silyl protection of alcs. under mild conditions. The synthetic protocol involved a two-component solvent-free reaction between various hydroxyl-bearing substrates and hexamethyldisilazane (HMDS) as an inexpensive silylating agent using Fe3O4@H2L-Zn MNPs as a magnetically separable, recyclable and reusable heterogeneous catalyst. Fe3O4@H2L-Zn MNPs were also applied for the removal of silyl protecting groups from hydroxyl functions using water in DCM under green conditions. The catalyst demonstrated good to excellent catalytic yield efficiency for both the reactions compared to the com. metal-based catalysts under green conditions for a wide range of substrates.

Korade, Zeljka; Allen, Luke B.; Anderson, Allison; Tallman, Keri A.; Genaro-Mattos, Thiago C.; Porter, Ned A.; Mirnics, Karoly published the artcile< Trazodone effects on developing brain>, Product Details of C27H44O, the main research area is Dhcr7 genotype trazodone brain.

Abstract: Trazodone (TRZ) is a commonly prescribed antidepressant with significant off-label use for insomnia. Recognizing the well-documented, disruptive effect of 7-DHC on brain development, we designed a study to analyze TRZ effects during pregnancy. Utilizing an in vivo model and human biomaterial, our studies were designed to also account for drug interactions with maternal or offspring Dhcr7 genotype. In a maternal exposure model, we found that TRZ treatment increased 7-DHC and decreased desmosterol levels in brain tissue in newborn pups. We also observed interactions between Dhcr7 mutations and maternal TRZ exposure, giving rise to the most elevated toxic oxysterols in brains of Dhcr7+/- pups with maternal TRZ exposure, independently of the maternal Dhcr7 genotype. Therefore, TRZ use during pregnancy might be a risk factor for in utero development of a neurodevelopmental disorder, especially when the unborn child is of DHCR7+/- genotype. The effects of TRZ on 7-DHC was corroborated in human serum samples. We analyzed sterols and TRZ levels in individuals with TRZ prescriptions and found that circulating TRZ levels correlated highly with 7-DHC. The abundance of off-label use and high prescription rates of TRZ might represent a risk for the development of DHCR7 heterozygous fetuses. Thus, TRZ use during pregnancy is potentially a serious public health concern.
