Mahmoudabadi, Samane Zarei published the artcileInvestigation of COSMO-SAC model for solubility and cocrystal formation of pharmaceutical compounds, Recommanded Product: rel-(1R,2R,4R)-1,7,7-Trimethylbicyclo[2.2.1]heptan-2-ol, the main research area is acetone heptane cocrystal solubility pharmaceutical.

In this study, a predictive model named COSMO-SAC was investigated in solid/liquid equilibrium for pharmaceutical compounds The examined properties were the solubility of drug in the pure and mixed solvents, octanol/water partition coefficient, and cocrystal formation. The results of the original COSMO-SAC model (COSMO-SAC (2002)) was compared with a semi-predictive model named Flory-Huggins model and a revised version of the COSMO-SAC (COSMO-SAC (2010)). The results indicated the acceptable accuracy of the COSMO-SAC (2002) in the considered scope. The results emphasized on the suitability of the COSMO-SAC model for simple mols. containing C, H, and O by covalent and hydrogen bonding interactions. Applicability of the COSMO-SAC for more complicated mols. made of various functional groups such as COO and COOH doubly requires more modification in the COSMO-SAC.

Ciera, Lucy published the artcileElectrospinning repellents in polyvinyl alcohol-nanofibers for obtaining mosquito-repelling fabrics, Name: 2-(2-Hydroxypropan-2-yl)-5-methylcyclohexanol, the main research area is polyvinyl alc nanofiber repellent electrospinning mosquito repelling fabric; mech property; electrospinning; emulsion; micro-capsules; mosquito; repellent.

Recently, the use of repellents for preventing the transmission of mosquito-borne diseases is getting increasingly more attention. However, most of the current repellents are volatile in nature and must be frequently re-applied as their efficacy is only limited to a short period of time. Therefore, a slow release and abrasion-resistant mechanism is needed for prolonging the protection time of the repellents. The focus of this study is on the direct micro-encapsulation of repellents from an emulsion and integration of already encapsulated repellents into nanofibres via electrospinning. Different repellents were electrospun in polyvinyl alc. (PVA) nanofibrous structures, namely p-menthane-3,8-diol micro-capsules, permethrin, chilli and catnip oil. The repellents were successfully incorporated in the nanofibres and the tensile properties of the resulting samples did not have a significant change. This means that the newly created textiles were identical to current PVA nanofibrous textiles with the added benefit of being mosquito repellent. Principally, all incorporated repellents in the nanofibrous structures showed a significantly reduced number of mosquito landings compared to the control. Consequently, the currently described method resulted in a new and very effective repelling textile material that can be used in the prevention against mosquito-associated diseases.

Barasa, Stephen S. published the artcileRepellent activities of stereoisomers of p-menthane-3,8-diols against Anopheles gambiae (Diptera: Culicidae), Application In Synthesis of 42822-86-6, the main research area is menthanediol stereoisomer insect repellent Anopheles.

Four stereoisomers of p-menthane-3,8-diol, which make up the natural product obtained from Eucalyptus citriodora, were synthesized through stereoselective procedures. Repellency assays showed that all the four were equally active against Anopheles gambiae s.s. Racemic blends and the diastereoisomeric mixture of all the four isomers were also equally repellent. 1-α-Terpineol, with a single hydroxyl function at C-8 and unsaturation at C-8, and menthol, with a single hydroxyl function at C-3, were not repellent. The practical implication of these results is discussed.

Li, Qiaofeng published the artcileA network pharmacology-based approach to explore the active ingredients and molecular mechanism of Lei-gong-gen formula granule on a spontaneously hypertensive rat model, COA of Formula: C10H18O, the main research area is Lei gong gen spontaneous hyertension NOS3 SRC; Centella asiatica (L.) Urb.; Eclipta prostrata (L.) L.; Hypertension; Network pharmacology; Smilax glabra Roxb..

Lei-gong-gen formula granule (LFG) is a folk prescription derived from Zhuang nationality, the largest ethnic minority among 56 nationalities in China. It consists of three herbs, namely Eclipta prostrata (L.) L., Smilax glabra Roxb, and Centella asiatica (L.) Urb. It has been widely used as health protection tea for hundreds of years to prevent hypertension in Guangxi Zhuang Autonomous Region. The purpose of this study is to validate the antihypertensive effect of LFG on the spontaneously hypertensive rat (SHR) model, and to further identify the effective components and anti-hypertension mechanism of LFG. The effects of LFG on blood pressure, body weight, and heart rate were investigated in vivo using the SHR model. The levels of NO, ANG II, and ET-1 in the serum were measured, and pathol. changes in the heart were examined by H&E staining. The main active components of LFG, their corresponding targets, and hypertension associated pathways were discerned through network pharmacol. anal. based on the Traditional Chinese Medicine Systems Pharmacol. (TCMSP), Traditional Chinese Medicine Integrated Database (TCMID), and the Bioinformatics Anal. Tool for Mol. Mechanism of Traditional Chinese Medicine (BATMAN-TCM). Then the predicted results were further verified by mol. biol. experiments such as RT-qPCR and western blot. Addnl., the potential active compounds were predicted by mol. docking technol., and the chem. constituents of LFG were analyzed and identified by UPLC-QTOF/MS technol. Finally, an in vitro assay was performed to investigate the protective effects of potential active compounds against hydrogen peroxide (H2O2) induced oxidative damage in human umbilical vein endothelial cells (HUVEC). LFG could effectively reduce blood pressure and increase serum NO content in SHR model. Histol. results showed that LFG could ameliorate pathol. changes such as cardiac hypertrophy and interstitial inflammation. From network pharmacol. anal., 53 candidate active compounds of LFG were collected, which linked to 765 potential targets, and 828 hypertension associated targets were retrieved, from which 12 overlapped targets both related to candidate active compounds from LFG and hypertension were screened and used as the potential targets of LFG on antihypertensive effect. The mol. biol. experiments of the 12 overlapped targets showed that LFG could upregulate the mRNA and protein expressions of NOS3 and proto-oncogene tyrosine-protein kinase SRC (SRC) in the thoracic aorta. Pathway enrichment anal. showed that the PI3K-AKT signaling pathway was closely related to the expression of NOS3 and SRC. Moreover, western blot results showed that LFG significantly increased the protein expression levels of PI3K and phosphorylated AKT in SHR model, suggesting that LFG may active the PI3K-AKT signaling pathway to decrease hypertension. Mol. docking study further supported that p-hydroxybenzoic acid, cedar acid, shikimic acid, salicylic acid, nicotinic acid, linalool, and histidine can be well binding with NOS3, SRC, PI3K, and AKT. UPLC-QTOF/MS anal. confirmed that p-hydroxybenzoic acid, shikimic acid, salicylic acid, and nicotinic acid existed in LFG. Pre-treatment of HUVEC with nicotinic acid could alleviate the effect on cell viability induced by H2O2 and increase the NO level in cell supernatants. LFG can reduce the blood pressure in SHR model, which might be attributed to increasing the NO level in serum for promoting vasodilation via upregulating SRC expression level and activating the PI3K-AKT-NOS3 signaling pathway. Nicotinic acid might be the potential compound for LFG antihypertensive effect.

The physicochem. properties, structural features and immunomodulatory effects of the white asparagus (Asparagus officinalis L.) skin polysaccharides (WASP) were systematically studied. WASP showed a pectic-like structure with a relatively low degree of esterification (DE, 18%); the weight-average mol. weight (Mw) and intrinsic viscosity were 76.1 kDa and 13 mL/g, resp. Structurally, the dominated sugar residue of WASP was 4-α-D-GalpA (39.7 mol%), while other residues including α-L-Araf, 3-α-L-Rhap, 2,4-α-L-Rhap, and 4-β-D-Galp were also detected with a comparable amount A proposed structure of WASP was also presented. Physiol., WASP could modulate the immune response of RAW 264.7 macrophages through increasing the release of immune factors (IL-6, TNF-α and IL-10) and improving the expression of mRNA. To conclude, the pectic-like polysaccharides from white asparagus (Asparagus officinalis L.) skin could be potentially used as an immunomodulatory agent in functional food.

Mahanta, Bhaskar Protim published the artcilePhytotoxic essential oil from black turmeric (Curcuma caesia Roxb.) rhizome: Screening, efficacy, chemical basis, uptake and mode of transport, Category: alcohols-buliding-blocks, the main research area is black turmeric rhizome phytotoxic essential oil screening transport.

Plant-based phytotoxins play an important role in plant-plant interaction and are of great promise for the development of bioherbicide. In this study, screening of essential oils from six different Curcuma rhizomes identified black turmeric (Curcuma caesia Roxb.) oil as an efficient growth inhibitor in wheatgrass coleoptile bioassay (IC50 57.1μg/mL). The phytotoxic efficacy of this oil was further confirmed through the dose dependent (10.0-300.0μg/mL) inhibition of germination, coleoptile and radicle growth of wheatgrass seeds in water medium (IC50 176.7, 90.6 and 93.0μg/mL resp.) and the pre-germinated seeds in agar medium. Activity-guided fractionation and purification of the crude oil identified curzerenone, a major furanosesquiterpene in this oil as the most active phytotoxin (IC50 13.0μg/mL in coleoptile bioassay; 188.3, 34.7 and 36.7μg/mL resp. in water medium). Structure-activity relationship study indicated the importance of all the functional groups for its phytotoxicity. A significant contribution by the oxygenated monoterpenes towards oil phytotoxicity was also evidenced. Though inhibitory efficacy of the oil was comparatively weak in soil, a profound activity through aerial diffusion was observed against germination and/or growth of fresh and pre-germinated wheatgrass seeds (IC50 1.4-6.2 mg/L air). The study also confirmed the uptake of active phytotoxins with no detectable transformation by the seeds in water and their persistence in the soil for at least one and half months. Further, its applicability was demonstrated through an efficient post-emergence growth inhibition (IC50 37.0-81.4μg/mL) of bermudagrass weed in water and agar medium.

Huang, Zhi published the artcileA novel polysaccharide from the roots of Millettia Speciosa Champ: preparation, structural characterization and immunomodulatory activity, Computed Properties of 59-23-4, the main research area is Millettia root polysaccharide fucose arabinose galactose pinocytosis; Immunomodulatory activity; Millettia Speciosa champ polysaccharide; Structural characterization.

A novel polysaccharide fraction (MSCP2) was extracted and isolated from the roots of Millettia Speciosa Champ. Structural characterization revealed that MSCP2 had an average mol. weight of 2.85 × 104 Da and was composed of fucose, arabinose, galactose, glucose and xylose with a ratio of 2.20: 2.52: 4.04: 87.29: 3.96. Methylation anal. and NMR (NMR) anal. showed that the main glycosidic linkage types of MSCP2 were proved to be α-D-Glcp-(1→, →4)-α-D-Glcp-(1→, →4)-α-D-Xylp-(1→, →6)-α-D-Galp-(1→, α-L-Araf-(1→, →3,4)-β-L-Fucp-(1→) and →4)-α-D-GalpA-(1→). The immunomodulatory assay suggested that MSCP2 could significantly improve the pinocytic capacity and increase the secretion of nitric oxide (NO) and cytokines by regulating the corresponding mRNA expression in RAW 264.7 cells. The data from the membrane receptor assay demonstrated that the potential mechanisms of MSCP2-induced macrophage activation were mainly through toll-like receptor 4 (TLR4), scavenger receptor type A (SRA) and glucan receptor (GR)-mediated signaling pathways. These results suggested that MSCP2 can be developed as a promising immunomodulatory agent in functional foods.

Hao, Huili published the artcileStructural characterization and immunostimulatory activity of a novel polysaccharide from green alga Caulerpa racemosa var peltata, Safety of (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is Caulerpa galacturonic acid polysaccharide immunostimulant; Caulerpa racemosa var peltata; Immunostimulatory activity; Polysaccharide; Structural characteristics.

A novel water-soluble polysaccharide (named CRVP-1) was successfully obtained from Caulerpa racemosa var peltata by hot-water extraction, ethanol precipitation, and column chromatog. The structure of CRVP-1 was characterized by HPGPC, HPAEC-PAD, FT-IR, GC-MS and NMR. The structural anal. indicated that CRVP-1 possessed a sulfate content of 25.8% ± 0.7% and was a heteropolysaccharide with an average mol. weight of 29.68 kDa, and composed of mannose, galactose, glucose, galacturonic acid, and glucuronic acid with rates of 92.1%, 2.9%, 1.8%, 1.7% and 1.2%, resp., owning a backbone structure of (1-6)-linked a-D-Manp residues with (1-4)-linked a-D-Manp and (1-2)-linked a-D-Manp residues and side chain that was consisted of (1-4)-linked b-D-Galp residues. The immunostimulatory assay revealed that CRVP-1 had significant effects on the proliferation of macrophage, production of NO and secretion of cytokines (TNF-a, IL-1b and IL-6). These findings provide a scientific basis for further utilization of polysaccharides from C. racemosa var peltata.

Coff, Lachlan published the artcileIdentifying glycan motifs using a novel subtree mining approach, Name: (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is glycan motif subtree mining algorithm; Carbohydrate; Frequent subtree mining; Glycan; Glycobiology; Machine learning; Microarray; Motif.

Glycans are complex sugar chains, crucial to many biol. processes. By participating in binding interactions with proteins, glycans often play key roles in host-pathogen interactions. The specificities of glycan-binding proteins, such as lectins and antibodies, are governed by motifs within larger glycan structures, and improved characterisations of these determinants would aid research into human diseases. Identification of motifs has previously been approached as a frequent subtree mining problem, and we extend these approaches with a glycan notation that allows recognition of terminal motifs. In this work, we customised a frequent subtree mining approach by altering the glycan notation to include information on terminal connections. This allows specific identification of terminal residues as potential motifs, better capturing the complexity of glycan-binding interactions. We achieved this by including addnl. nodes in a graph representation of the glycan structure to indicate the presence or absence of a linkage at particular backbone carbon positions. Combining this frequent subtree mining approach with a state-of-the-art feature selection algorithm termed min.-redundancy, maximum-relevance (mRMR), we have generated a classification pipeline that is trained on data from a glycan microarray. When applied to a set of commonly used lectins, the identified motifs were consistent with known binding determinants. Furthermore, logistic regression classifiers trained using these motifs performed well across most lectins examined, with a median AUC value of 0.89. We present here a new subtree mining approach for the classification of glycan binding and identification of potential binding motifs. The Carbohydrate Classification Accounting for Restricted Linkages (CCARL) method will assist in the interpretation of glycan microarray experiments and will aid in the discovery of novel binding motifs for further exptl. characterization.

Feng, Yuqin published the artcileRecent advances in Agaricus bisporus polysaccharides: Extraction, purification, physicochemical characterization and bioactivities, Category: alcohols-buliding-blocks, the main research area is review Agaricus polysaccharide galactose extraction physicochem property food composition.

Agaricus bisporus (A. bisporus), known as a cultivated mushroom or button mushroom, is a very important edible and medicinal basidiomycete fungus. The numerous health benefits of A. bisporus may be related to their polysaccharides, which have significant dietary value and bioactivity, including immunity stimulation and high antioxidant, anticancer, hepatoprotection, anti-inflammation and anti-obesity functions. In general, the extraction method of A. bisporus polysaccharides (ABPs) is relatively simple, and the yield from enzyme-assisted extraction is the highest among various extraction methods. The monosaccharide composition anal. revealed that ABPs mainly consist of glucose, galactose, fucose and xylose, which each have a backbone composed of (1→6)- and (1→4)-linked α-glucan or alternating (1→4)- and (1→6)-linked β-glucan. The biol. activity of ABPs may vary significantly depending on their source, composition, structural properties, and purity, and it is highly correlated with mol. weight (MW) and the monosaccharide components. Therefore, this review aims to introduce the extraction methods, chem. structure, and biol. activity of ABPs which may provide a theor. basis for the further development and utilization of polysaccharides and have important reference value for the future study of the relationship between structural features and biol. activities.
