Bacterial Analogs to Cholesterol Affect Dimerization of Proteorhodopsin and Modulates Preferred Dimer Interface was written by Sefah, Eric;Mertz, Blake.

Hopanoids, the bacterial analogs of sterols, are ubiquitous in bacteria and play a significant role in organismal survival under stressful environments. Unlike sterols, hopanoids have a high degree of variation in the size and chem. nature of the substituent attached to the ring moiety, leading to different effects on the structure and dynamics of biol. membranes. While it is understood that hopanoids can indirectly tune membrane phys. properties, little is known on the role that hopanoids may play in affecting the organization and behavior of bacterial membrane proteins. The authors used coarse-grained mol. dynamics simulations to characterize the effects of two hopanoids, diploptene (DPT) and bacteriohopanetetrol (BHT), on the oligomerization of proteorhodopsin (PR) in a model membrane composed of 1-palmitoyl-2-oleoyl-sn-glycero-3-phophoethanolamine (POPE) and 1-palmitoyl-2-oleoyl-sn-3-phosphoglycerol (POPG). PR is a bacterial membrane protein that functions as a light-activated proton pump. The authors chose PR based on its ability to adopt a distribution of oligomeric states in different membrane environments. Furthermore, the efficiency of proton pumping in PR is intimately linked to its organization into oligomers. The authors’ results reveal that both BHT and DPT indirectly affect dimerization by tuning membrane properties in a fashion that is concentration-dependent. Variation in their interaction with PR in the membrane-embedded and the cytoplasmic regions leads to distinctly different effects on the plasticity of the dimer interface. BHT has the ability to intercalate between monomers in the dimeric interface, whereas DPT shifts dimerization interactions via packing of the interleaflet region of the membrane. The authors’ results show a direct relation between hopanoid structure and lateral organization of PR, providing a first glimpse at how these bacterial analogs to eukaryotic sterols produce very similar biophys. effects within the cell membrane.

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Computed Properties of C21H44O5

Stress response to oxytetracycline and microplastic-polyethylene in wheat (Triticum aestivum L.) during seed germination and seedling growth stages was written by Bao, Yanyu;Pan, Chengrong;Li, Dezheng;Guo, Aiyun;Dai, Fengbin.

Much efforts have been devoted to clarify the phytotoxicity of individual contaminants in plants, such as individual antibiotic and microplastic; however, little is known about the phytotoxicity of their combined exposure. Here, we investigated the effects of individual and combined exposure of wheat (Triticum aestivum L.) (Xiaoyan 22) to oxytetracycline (OTC) and polyethylene (PE) microplastics using physiol. and metabolic profilings. During the seed germination stage, OTC induced phytotoxicity, as observed through the changes of root elongation, sprout length, fresh weight and the vitality index, with significant effect at the 50 and 150 mg路L-1 levels; the effect of PE microplastics depended on the OTC level in the combined exposure groups. During seedling cultivation, catalase (CAT) and ascorbate peroxidase (APX), as antioxidant enzyme indexes, were sensitive to OTC exposure stress, although OTC was not determined in leaves. Untargeted metabolomics of wheat leaves revealed OTC concentration-, metabolite class- and PE-dependent metabolic responses. Dominant metabolites included carboxylic acids, alcs., and amines in the control group and all treatment groups. Compared to only OTC treatment, PE reprogrammed carboxylic acid and alc. profiles in combined exposure groups with obvious separation in PLS-DA. Combined exposure induced fewer metabolites than OTC exposure alone at the 5 and 50 mg路L-1 levels. The shared metabolite numbers were higher in the OTC groups than in the PE-OTC groups. Pathway enrichment anal. showed a drift in metabolic pathways between individual and combined exposure to OTC and PE, which included glyoxylate and dicarboxylate metabolism, amino acid metabolism and isoquinoline alkaloid biosynthesis. Among metabolites, aromatic acids and amino acids were more sensitive to combined exposure than individual exposure. These results contribute to clarifying the underlying mechanisms of phytotoxicity of individual and combined exposure to OTC and PE.

Investigation of therapeutic effect of curcumin 伪 and 尾 glucoside anomers against Alzheimer’s disease by the nose to brain drug delivery was written by Ahmadi, Nahid;Hosseini, Mir-Jamal;Rostamizadeh, Kobra;Anoush, Mahdieh.

Alzheimer’s disease (AD) is one of the greatest geriatric medicinal challenges of our century and is the main disease leading to dementia. Despite extensive scientific research advances, available disease-modifying treatment strategies remained limited; thus, increasing demand for new drugs. In recent years, medicinal plants attracted attention due to their potential role in dementia. In the present study, 伪 and 尾 anomers of curcumin glucosides (CGs) were synthesized and evaluated for Alzheimer’s treatment. CGs were synthesized by fusion reaction as a novel and easy method with more advantages (high yield, short reaction time, and low chems.), and the products were characterized using HNMR. Wistar male rats were used to administer different treatments. They divided into control, sham, Alzheimer, and test groups (Alzheimer + 伪 anomer and Alzheimer + 尾 anomer). Animals received normal saline, Scopolamine (1 mg/kg), high dose anomers, scopolamine, and two doses (12.5 and 25 mg/kg) of anomers, resp., for 10 days. Then the Morris Water Maze (MWM) test was performed on all animals. Finally, the animals’ brains were extracted and homogenized for glutathione, acetylcholine esterase activity, protein carbonyl, and lipid peroxide level detection. The escape latency and the distance towards the hidden platform in Morris water maze in the Alzheimer group were significantly higher than both the control and test groups. Besides, there were no significant differences between sham and control groups in all tests. Both anomers led to a significant increase in glutathione, and acetylcholine levels while they caused a decrease in lipid peroxidation and protein carbonyl levels in brain tissue. It seems that intranasal administration of both anomers pos. influenced maze learning in scopolamine receiving subjects. Although both anomers resulted in similar biochem. tests, a higher dose of 尾 anomer indicated better results than 伪 anomer not only in behavioral tests but also in biochem. tests.

A technique for rapid source apportionment applied to ambient organic aerosol measurements from a thermal desorption aerosol gas chromatograph (TAG) was written by Zhang, Yaping;Williams, Brent J.;Goldstein, Allen H.;Docherty, Kenneth S.;Jimenez, Jose L..

We present a rapid method for apportioning the sources of atm. organic aerosol composition measured by gas chromatog.-mass spectrometry methods. Here, we specifically apply this new anal. method to data acquired on a thermal desorption aerosol gas chromatograph (TAG) system. Gas chromatograms are divided by retention time into evenly spaced bins, within which the mass spectra are summed. A previous chromatogram binning method was introduced for the purpose of chromatogram structure deconvolution (e.g., major compound classes). Here we extend the method development for the specific purpose of determining aerosol samples’ sources. Chromatogram bins are arranged into an input data matrix for pos. matrix factorization (PMF), where the sample number is the row dimension and the mass-spectra-resolved eluting time intervals (bins) are the column dimension. Then two-dimensional PMF can effectively do three-dimensional factorization on the three-dimensional TAG mass spectra data. The retention time shift of the chromatogram is corrected by applying the median values of the different peaks’ shifts. Bin width affects chem. resolution but does not affect PMF retrieval of the sources’ time variations for low-factor solutions A bin width smaller than the maximum retention shift among all samples requires retention time shift correction. A six-factor PMF comparison among aerosol mass spectrometry (AMS), TAG binning, and conventional TAG compound integration methods shows that the TAG binning method performs similarly to the integration method. However, the new binning method incorporates the entirety of the data set and requires significantly less pre-processing of the data than conventional single compound identification and integration. In addition, while a fraction of the most oxygenated aerosol does not elute through an underivatized TAG anal., the TAG binning method does have the ability to achieve mol. level resolution on other bulk aerosol components commonly observed by the AMS.

The posttranslational addition of a farnesyl moiety to the Ras oncoprotein is essential for its membrane localization and is required for both its biol. activity and ability to induce malignant transformation. We describe the design and synthesis of a farnesyl pyrophosphate (FPP) analog, 8-anilinogeranyl pyrophosphate, PhNHCH2CMe:CH(CH2)2CMe:CHCH2OP2O6H3 [AGPP (I)], in which the 蠅-terminal isoprene unit of the farnesyl group has been replaced with an aniline functionality. The key steps in the synthesis are the reductive amination of the 伪,尾-unsaturated aldehyde, OHCCMe:CH(CH2)2CMe:CHCH2OAc-(E,E), to form the lipid analog, PhNHCH2CMe:CH(CH2)2CMe:CHCH2OAc-(E,E), and the subsequent conversion of the allylic alc., PhNHCH2CMe:CH(CH2)2CMe:CHCH2OH-(E,E), to the chloride, PhNHCH2CMe:CH(CH2)2CMe:CHCH2Cl-(E,E), via Ph3PCl2 followed by displacement with [(n-Bu)4N]3HP2O7 to give I. I is a substrate for protein farnesyltransferase (FTase) and is transferred to Ras by FTase with the same kinetics as the natural substrate, FPP. I is highly selective, showing little inhibitory activity against either geranylgeranyl-protein transferase type I (GGTase I) (Ki = 0.06 渭M, IC50 = 20 渭M) or squalene synthase (IC50 = 1000 渭M). I is the first efficiently transferable analog of FPP to be modified at the 蠅-terminus that provides a platform from which addnl. analogs can be made to probe the biol. function of protein farnesylation.

Octyl acetate (cas: 112-14-1) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Safety of Octyl acetate

The paper describes the results of using Raman spectroscopy to study the canvases of Russian avant-garde artists. The study aimed to identify stable signs of paints for the recognition of counterfeits. The subject of the research was zinc white as a component of paints used by the 20th-century Russian avant-garde. Temporal changes occurring with them are due to chem. reactions of organic paint components with whites and with each other. The study shows that Raman spectroscopy is the most sensitive method for detecting ZnO time markers. Its results are compared with the results of pyrolysis-gas chromatog., mass spectrometry, and X-ray anal. of paints from paintings from the Russian avant-garde of the early, middle, and late twentieth century. The study results demonstrate that the paint compositions of the early and late 20th Century have significant similarities. The result of their aging is the appearance of products of thermal desorption and pyrolysis in the form of a homologous series of alcs. and aromatic hydrocarbons formed during the destruction and oxidation of oleic, linoleic, linolenic, palmitic, stearic acids, and/or azelaic acid. These acids are found in flaxseed oil. Zinc white of the early 20th century contains significant additions of gypsum. The composition of the components of mid-century paints is much less diverse. Genuine paintings contain homologous series of fatty acids sorbed on zinc oxide. The paper analyzes historical reasons for this phenomenon. The research shows that one of the stable signs of falsification is the use of titanium white and organic catalysis products based on them. The results of gas chromatog. and mass spectrometry and Raman spectroscopy are supplemented by X-ray phase and X-ray fluorescence anal. The paper provides detailed reference data on the spectra of Raman light scattering, thermal desorption, and pyrolysis of paints of the studied canvases and shows the differences in the mass spectra of genuine paintings and falsifications.

Rice rhizodeposition promotes the build-up of organic carbon in soil via fungal necromass was written by Luo, Yu;Xiao, Mouliang;Yuan, Hongzhao;Liang, Chao;Zhu, Zhenke;Xu, Jianming;Kuzyakov, Yakov;Wu, Jinshui;Ge, Tida;Tang, Caixian.

Rice rhizodeposition plays an important role in carbon sequestration in paddy soils. However, the pathways through which rice rhizodeposits contribute to soil organic C (SOC) formation are poorly understood because of specific paddy soil conditions. Furthermore, microbial necromass has been largely ignored in studies examining the contribution of rhizodeposits to C sequestration during plant growth. To evaluate the contribution of microbial necromass to SOC formation via rhizodeposition, rice (Oryza sativa L.) plants were continuously labeled with 13CO2 for 38 days under ambient (aCO2, 400渭L L-1) or elevated CO2 (eCO2, 800渭L L-1) in a paddy field at two levels of N fertilization. The distributions of photosynthetic-13C in the shoots and roots, microbial communities, and SOC fractions were quantified. eCO2 increased plant growth and, consequently, the total 13C incorporated into the shoots, roots, and SOC compared to aCO2, while N fertilization (100 kg N ha-1) decreased root biomass and rhizodeposits in the soil and microbial pools, including living biomass (phospholipid fatty acids, PLFA) and microbial necromass (amino sugars). Rhizodeposits were initially immobilized mainly by bacteria and preferentially recovered in fungal necromass (glucosamine). While 13C incorporation into PLFAs was slightly increased during plant growth, 13C in microbial necromass increased greatly between the tillering and booting stages. Fungal necromass, which is less decomposable compared to bacterial residues, was the largest contributor to C sequestration with rhizodeposits via the mineral-associated SOC fraction, particularly under elevated CO2 without N fertilization. This study reveals the significance of the C pathways from rhizodeposits through fungal necromass and organo-mineral associations for the build up of SOC in paddy fields.

In this work we introduce a novel filtering and mol. modeling pipeline based on a fingerprint and descriptor similarity procedure, coupled with mol. docking and mol. dynamics (MD), to select potential novel quoinone outside inhibitors (QoI) of cytochrome bc1 with the aim of determining the same or different chromophores to usual. The study was carried out using the yeast cytochrome bc1 complex with its docked ligand (stigmatellin), using all the fungicides from FRAC code C3 mode of action, 8617 Drugbank compounds and 401,624 COCONUT compounds The introduced drug repurposing pipeline consists of compound similarity with C3 fungicides and mol. docking (MD) simulations with final QM/MM binding energy determination, while aiming for potential novel chromophores and perserving at least an amide (R1HN(C=O)R2) or ester functional group of almost all up to date C3 fungicides. 3D descriptors used for a similarity test were based on the 280 most stable Padel descriptors. Hit compounds that passed fingerprint and 3D descriptor similarity condition and had either an amide or an ester group were submitted to docking where they further had to satisfy both Chemscore fitness and specific conformation constraints. This rigorous selection resulted in a very limited number of candidates that were forwarded to MD simulations and QM/MM binding affinity estimations by the ORCA DFT program. In this final step, stringent criteria based on (a) sufficiently high frequency of H-bonds; (b) high interaction energy between protein and ligand through the whole MD trajectory; and (c) high enough QM/MM binding energy scores were applied to further filter candidate inhibitors. This elaborate search pipeline led finaly to four Drugbank synthetic lead compounds (DrugBank) and seven natural (COCONUT database) lead compounds-tentative new inhibitors of cytochrome bc1.

Distinct lipid membrane interaction and uptake of differentially charged nanoplastics in bacteria was written by Dai, Shang;Ye, Rui;Huang, Jianxiang;Wang, Binqiang;Xie, Zhenming;Ou, Xinwen;Yu, Ning;Huang, Cheng;Hua, Yuejin;Zhou, Ruhong;Tian, Bing.

Nanoplastics have been recently found widely distributed in our natural environment where ubiquitously bacteria are major participants in various material cycles. Understanding how nanoplastics interact with bacterial cell membrane is critical to grasp their uptake processes as well as to analyze their associated risks in ecosystems and human microflora. However, little is known about the detailed interaction of differentially charged nanoplastics with bacteria. The present work exptl. and theor. demonstrated that nanoplastics enter into bacteria depending on the surface charges and cell envelope structural features, and proved the shielding role of membrane lipids against nanoplastics. Pos. charged polystyrene nanoplastics (PS-NH2, 80 nm) can efficiently translocate across cell membranes, while neg. charged PS (PS-COOH) and neutral PS show almost no or much less efficacy in translocation. Mol. dynamics simulations revealed that the PS-NH2 displayed more favorable electrostatic interactions with bacterial membranes and was subjected to internalisation through membrane penetration. The pos. charged nanoplastics destroy cell envelope of Gram-pos. B. subtilis by forming membrane pore, while enter into the Gram-neg. E. coli with a relatively intact envelope. The accumulated pos. charged nanoplastics conveyed more cell stress by inducing a higher level of reactive oxygen species (ROS). However, the subsequently released membrane lipid-coated nanoplastics were nearly nontoxic to cells, and like wise, stealthy bacteria wrapped up with artificial lipid layers became less sensitive to the pos. charged nanoplastics, thereby illustrating that the membrane lipid can shield the strong interaction between the pos. charged nanoplastics and cells. Our findings elucidated the mol. mechanism of nanoplastics interaction and accumulation within bacteria, and implied the shielding and internalization effect of membrane lipid on toxic nanoplastics could promote bacteria for potential plastic bioremediation. This study involved multiple reactions and reactants, such as (2R,9Z)-1-(((2-Aminoethoxy)(hydroxy)phosphoryl)oxy)-3-(palmitoyloxy)propan-2-yl oleate (cas: 26662-94-2Recommanded Product: 26662-94-2).

(2R,9Z)-1-(((2-Aminoethoxy)(hydroxy)phosphoryl)oxy)-3-(palmitoyloxy)propan-2-yl oleate (cas: 26662-94-2) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters contain a carbonyl center, which gives rise to 120掳 C鈥揅鈥揙 and O鈥揅鈥揙 angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C鈥揙鈥揅 bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

(2R,9Z)-1-(((2-Aminoethoxy)(hydroxy)phosphoryl)oxy)-3-(palmitoyloxy)propan-2-yl oleate (cas: 26662-94-2) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Application In Synthesis of (2R,9Z)-1-(((2-Aminoethoxy)(hydroxy)phosphoryl)oxy)-3-(palmitoyloxy)propan-2-yl oleate

Osteoporosis and its associated fractures are highly prevalent in older women. Recent studies have shown that gut microbiota play important roles in regulating bone metabolism A previous randomized controlled trial (RCT) found that supplementation with Lactobacillus reuteri ATCC PTA 6475 (L.reuteri) led to substantially reduced bone loss in older women with low BMD. However, the total metabolic effects of L. reuteri supplementation on older women are still not clear. In this study, a post hoc anal. (not predefined) of serum metabolomic profiles of older women from the previous RCT was performed to investigate the metabolic dynamics over 1 yr and to evaluate the effects of L. reuteri supplementation on human metabolism Distinct segregation of the L. reuteri and placebo groups in response to the treatment was revealed by partial least squares-discriminant anal. Although no individual metabolite was differentially and significantly associated with treatment after correction for multiple testing, 97 metabolites responded differentially at any one time point between L. reuteri and placebo groups (variable importance in projection score >1 and p value <0.05). These metabolites were involved in multiple processes, including amino acid, peptide, and lipid metabolism Butyrylcarnitine was particularly increased at all investigated time points in the L. reuteri group compared with placebo, indicating that the effects of L. reuteri on bone loss are mediated through butyrate signaling. Furthermore, the metabolomic profiles in a case (low BMD) and control population (high BMD) of elderly women were analyzed to confirm the associations between BMD and the identified metabolites regulated by L. reuteri supplementation. The amino acids, especially branched-chain amino acids, showed association with L. reuteri treatment and with low BMD in older women, and may serve as potential therapeutic targets.
