MiR-21 expression stimulates osteoclast cells in the context of osteoclastogenesis. A previous report showed that NFκB-miR-21 pathway could serve as an innovative alternative to devise therapeutics for healing diabetic ulcers. Furthermore, our study demonstrated that a highly water-soluble curcuminoids-rich extract (CRE-Ter) inhibits osteoclastogenesis through NFκB pathway. The interplay between miR-21 and CRE-Ter in osteoclastogenesis has not yet been investigated. In this study, we examined the relation of CRE-Ter and miR-21 gene expression in receptor of the nuclear factor κB (NFκB) ligand (RANKL) – induced murine monocyte/macrophage RAW 264.7 cells, osteoclast cells, in osteoclastogenesis. Effect of CRE-Ter on generation of intracellular reactive oxygen species (ROS) was estimated by dichlorofluorescein diacetate (DCFH-DA). The results reveal that CRE-Ter reduced expression levels of miR-21 gene in osteoclasts. The inhibitory effects of CRE-Ter on in vitro osteoclastogenesis were evaluated by reduction in tartrate-resistant acid phosphatase (TRAP) content, and by reduction in expression levels of an osteoclast-specific gene, cathepsin K. Treatment of the osteoclast cells with CRE-Ter suppressed RANKL-induced NFκB activation including phospho-NFκB-p65, and phospho IκBα proteins. Western blot anal. revealed that NFκB inhibitor up-regulated CRE-Ter-promoted expression of phospho-NFκB-p65. In addition, CRE-Ter dose-dependently inhibited phospho-Akt expression. CRE-Ter also dose-dependently reduced DNA binding activity of NFκB and Akt as revealed by EMSA. ChIP assay revealed binding of NFκB-p65 to miR-21 promoters. In conclusion, our results demonstrate that CRE-Ter downregulates miR-21 gene expression in osteoclasts via a de novo mechanism, NFκB-Akt-miR-21 pathway. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Recommanded Product: 33171-05-0).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. 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.Recommanded Product: 33171-05-0

Distinct metabolomes and quality characteristics of vacuum-assisted osmosonic-pretreated Curcuma longa L. rhizomes subjected to different drying methods was written by Alolga, Raphael N.;Osae, Richard;Ibrahim, Traore S.;Onoja, Vitus;Apaliya, Maurice T.;Kwaw, Emmanuel;Huang, Feng-Qing. And the article was included in Industrial Crops and Products in 2022.Reference of 33171-05-0 The following contents are mentioned in the article:

This study sought to investigate the impact of four drying methods, thus, sun (S) drying, freeze (F) drying, relative humidity convective (RHC) drying and IR (IR) drying, on the metabolomes and quality characteristics of vacuum-assisted osmosonic-pretreated turmeric (Curcuma longa L.) slices. The quality characteristics examined included contents of marker compounds, antioxidant activities, total phenolic content (TPC), total flavonoid content (TFC), chromatic properties, sensory characteristics, rehydration ratios (RR), and moisture diffusivities. Using LC-Q/TOF-MS and chemometric analyses, the metabolomes of variously dried turmeric samples were examined In this regard, we found distinct metabolome differences between the samples. These differences translated into differential levels of three marker compounds, thus, curcumin, demethoxycurcumin and bisdemethoxycurcumin as captured by HPLC-DAD anal. Overall, F drying gave the best results for all parameters assessed except for effective moisture diffusivity. Specifically, the F dried samples possessed the highest contents of the marker compounds, curcumin (3.99 ± 0.01μg/mg), BDMC (0.275 ± 0.0006μg/mg), DMC (0.170 ± 0.0007μg/mg). The F dried samples also possessed the highest antioxidant activities, TPC, and TFC, chromatic and sensory characteristics. There were also marked differences in the rehydration ratios (RR), and the moisture diffusivities of the various dried samples. The RHC dried samples ranked second to the F dried samples for all quality parameters examined In summary, for all the quality characteristics examined, the following order in terms of suitability and potential industrial large-scale applicability of the various drying methods was deduced: F drying > RHC drying > IR drying > S drying. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Reference of 33171-05-0).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. 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.Reference of 33171-05-0

Alzheimer’s disease (AD) is a neurodegenerative disease associated with aging, and the number of people affected is rapidly increasing. Abnormally hyperphosphorylated tau filaments and extracellular deposits of amyloid β-peptides (Aβ) fibrils are two important pathol. hallmarks of AD. Currently, stopping the production of Aβ and blocking its aggregation is the main strategy for the treatment of AD. Turmeric is effective in treating neurodegenerative diseases, but there is no effective way to identify active compounds from their complicated chem. compositions Instead of using conventional extraction and separation methods with low efficiency and time-consuming, our group tried to use at. materials in high-throughput chem. screening due to their structural characteristics and the unique advantages of surface at. Herein, a novel at. zinc sites with hierarchical porous carbon (Zn-HPC) was synthesized to quickly screen potential inhibitors of Aβ aggregation in turmeric. As-combined Aβ@Zn-HPC demonstrates superior storage stability and high selectivity, outperforming the most reported supporters for ligand fishing. Five compounds with strong affinity on Aβ@Zn-HPC were selected by high-performance liquid chromatog.-hybrid linear ion trap/orbitrap mass spectrometer after incubation with turmeric extract Finally, it was shown that curcumin and bisdemethoxycurcumin can inhibit Aβ aggregation by using thioflavin-T fluorescence assay and biolayer interferometry. A new application for the accurate identification of Aβ aggregation inhibitors from turmeric were developed based on the active compounds possessing binding affinity to Aβ to inhibit its aggregation. The developed method could provide a promising tool for efficient drug discovery from natural product resources. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0COA of Formula: C19H16O4).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. 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. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C 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.

Predicting chemically-induced skin reactions. Part II: QSAR models of skin permeability and the relationships between skin permeability and skin sensitization was written by Alves, Vinicius M.;Muratov, Eugene;Fourches, Denis;Strickland, Judy;Kleinstreuer, Nicole;Andrade, Carolina H.;Tropsha, Alexander. And the article was included in Toxicology and Applied Pharmacology in 2015.Recommanded Product: 2-(2-(Hexyloxy)ethoxy)ethanol The following contents are mentioned in the article:

Skin permeability is widely considered to be mechanistically implicated in chem.-induced skin sensitization. Although many chems. have been identified as skin sensitizers, there have been very few reports analyzing the relationships between mol. structure and skin permeability of sensitizers and non-sensitizers. The goals of this study were to: (i) compile, curate, and integrate the largest publicly available dataset of chems. studied for their skin permeability; (ii) develop and rigorously validate QSAR models to predict skin permeability; and (iii) explore the complex relationships between skin sensitization and skin permeability. Based on the largest publicly available dataset compiled in this study, we found no overall correlation between skin permeability and skin sensitization. In addition, cross-species correlation coefficient between human and rodent permeability data was found to be as low as R² = 0.44. Human skin permeability models based on the random forest method have been developed and validated using OECD-compliant QSAR modeling workflow. Their external accuracy was high (Q²_ext = 0.73 for 63% of external compounds inside the applicability domain). The extended anal. using both exptl.-measured and QSAR-imputed data still confirmed the absence of any overall concordance between skin permeability and skin sensitization. This observation suggests that chem. modifications that affect skin permeability should not be presumed a priori to modulate the sensitization potential of chems. The models reported herein as well as those developed in the companion paper on skin sensitization suggest that it may be possible to rationally design compounds with the desired high skin permeability but low sensitization potential.

Tiaoganquzhi Decoction (TGQZD) is a traditional Chinese herbal formulation demonstrated to be a clin. effective treatment for nonalcoholic fatty liver disease (NAFLD), although details concerning its clin. mechanism are poor. This study aimed to explore the mechanism of TGQZD on improvement of inflammatory damage and dyslipidemia caused by NAFLD through the CGI-58/ROS/NLRP3 inflammasome pathway. In our research, the in vivo protective effects of TGQZD on HFD-induced liver injury in rats and in vitro using lipopolysaccharide (LPS) + palmitate (PA)-stimulated HepG-2 cells model. Histol. changes were evaluated by hematoxylin-eosin and Oil Red O staining. Inflammatory cytokines and protein expression were analyzed by ELISA, Real time PCR and western blotting. Liver function, blood lipids, free fatty acids (FFA), and reactive oxygen species (ROS) were determined by biochem. detection. Our results indicated that TGQZD exhibited anti-inflammatory activity, reduced the severity of NAFLD and ameliorated the pathol. changes. Further, TGQZD improved liver function and lipid metabolism in NAFLD rats. TGQZD lowered serum aspartate aminotransferase, alanine aminotransferase, triglyceride, and total cholesterol levels. TGQZD suppressed the formulation of FFA and ROS. It also reduced the expression and release of the inflammatory cytokine interleukin-1β by promoting CGI-58 expression and inhibiting the expression of FFA, TNF-α, and the NLRP3 inflammasome induced by ROS. TGQZD exhibited anti-inflammatory effects via the CGI-58, ROS and NLRP3 inflammasome pathway in vivo and in vitro, resp. Our findings demonstrated that TGQZD is a useful and effective therapeutic agent for treating NAFLD via promotion of CGI-58 to inhibit the expression of ROS-induced NLRP3 inflammasome.

Local tribes use the leaves of Ficus lepicarpa B. (Moraceae), a traditional Malaysian medicine, as a vegetable dish, a tonic, and to treat ailments including fever, jaundice and ringworm. The purpose of this study was to look into the possible therapeutic effects of F. lepicarpa leaf extract against carbon tetrachloride (CCl4)-induced liver damage in rats. The DPPH test was used to measure the antioxidant activity of plants. Gas chromatog.-mass spectrometry was used for the phytochem. anal. (GCMS). Six groups of male Sprague-Dawley rats were subjected to the following treatment regimens: control group, CCl4 alone, F. lepicarpa 400 mg/kg alone, CCl4 + F. lepicarpa 100 mg/kg, CCl4 + F. lepicarpa 200 mg/kg and CCl4 + F. lepicarpa 400 mg/kg. The rats were euthanized after two weeks, and biomarkers of liver function and antioxidant enzyme status were assessed. To assess the extent of liver damage and fibrosis, histopathol. and immunohistochem. examinations of liver tissue were undertaken. The total phenolic content and the total flavonoid content in methanol extract of F. lepicarpa leaves were 58.86 ± 0.04 mg GAE/g and 44.31 ± 0.10 mg CAE/g, resp. F. lepicarpa′s inhibitory concentration (IC50) for free radical scavenging activity was reported to be 3.73 mg/mL. In a dose-related manner, F. lepicarpa was effective in preventing an increase in serum ALT, serum AST and liver MDA. Histopathol. alterations revealed that F. lepicarpa protects against the oxidative stress caused by CCl4. The immunohistochem. results showed that proinflammatory cytokines (tumor necrosis factor-α, interleukin-6, prostaglandin E2) were suppressed. The antioxidative, anti-inflammatory, and free-radical scavenging activities of F. lepicarpa can be related to its hepatoprotective benefits.

Design, synthesis, and mechanistic investigations of phenylalanine derivatives containing a benzothiazole moiety as HIV-1 capsid inhibitors with improved metabolic stability was written by Xu, Shujing;Sun, Lin;Dick, Alexej;Zalloum, Waleed A.;Huang, Tianguang;Meuser, Megan E.;Zhang, Xujie;Tao, Yucen;Cherukupalli, Srinivasulu;Ding, Dang;Ding, Xiao;Gao, Shenghua;Jiang, Xiangyi;Kang, Dongwei;De Clercq, Erik;Pannecouque, Christophe;Cocklin, Simon;Liu, Xinyong;Zhan, Peng.

Further clin. development of I, a lead compound targeting HIV-1 capsid, is impeded by low antiviral activity and inferior metabolic stability. By modifying the benzene (region I) and indole of I, we identified two potent compounds II [R = propargyl, 4-NH₂Ph] with significantly improved metabolic stability. Compared to PF74, II [R = 4-NH₂Ph] displayed greater metabolic stability in human liver microsomes (HLMs) with half-life (t_1/2) 109-fold that of PF74. Moreover, mechanism of action (MOA) studies demonstrated that II [R = propargyl, 4-NH₂Ph] effectively mirrored the MOA of compounds that interact within the I interprotomer pocket, showing direct and robust interactions with recombinant CA, and 7u displaying antiviral effects in both the early and late stages of HIV-1 replication. Furthermore, MD simulation corroborated that II [R = 4-NH₂Ph] was bound to the I binding site, and the results of the online molinspiration software predicted that II [R = propargyl, 4-NH₂Ph] had desirable physicochem. properties. Unexpectedly, this series of compounds exhibited better antiviral activity than I against HIV-2, represented by compound II [R = propargyl] whose anti-HIV-2 activity was almost 5 times increased potency over I. Therefore, we have rationally redesigned the I chemotype to inhibitors with novel structures and enhanced metabolic stability in this study. We hope that these new compounds can serve as a blueprint for developing a new generation of HIV treatment regimens.

Overall survival of patients with low-grade glioma (LGG) has shown no significant improvement over the past 30 years, with survival averaging approx. 7 years. This study aimed to identify novel promising biomarkers of LGG and reveal its potential mol. mechanisms by integrated bioinformatics anal. The microarray datasets of GSE68848 and GSE4290 were selected from GEO database for integrated anal. In total, 293 overlapping differentially expressed genes (DEGs) were detected using the limma package. One hundred and eighty-eight nodes with 603 interactions were obtained from the establishment of protein-protein interaction (PPI) network. Functional and signaling pathway enriched were significantly correlated with the synapse and calcium signaling pathway, resp. Module anal. revealed eight hub genes with high connectivity, which included CHRM1, DLG2, GABRD, GRIN1, HTR2A, KCNJ3, KCNJ9, and NUSAP1, and they were markedly correlated with patients′ prognosis. The mining of the Gene Expression Profiling Interactive Anal. database and qPCR further confirmed the abnormal expression of these key genes with their prognostic value in LGG. We eventually predicted the 20 most vital small mol. drugs, which potentially reverse the carcinogenic state of LGG, as per the CMap (connectivity map) database and these DEGs, and MS-275 (enrichment score = -0.939) was considered as the most promising small mol. to treat LGG. In conclusion, our study provided eight reliable novel mol. biomarkers for diagnosis, prognosis prediction, and treatment targets for LGG. These conclusions will contribute to a better comprehension of mol. mechanisms fundamental to LGG occurrence and progression, and providing new insights for future development of genomic individualized treatment in LGG.

A major risk for patients having estrogen receptor α (ERα)-pos. breast cancer is the recurrence of drug-resistant metastases after initial successful treatment with endocrine therapies. Recent studies have implicated a number of activating mutations in the ligand-binding domain of ERα that stabilize the agonist conformation as a prominent mechanism for this acquired resistance. There are several critical gaps in our knowledge regarding the specific pharmacophore requirements of an antagonist that could effectively inhibit all or most of the different mutant ERs. To address this, we screened various chemotypes for blocking mutant ER-mediated transcriptional signaling and identified RU58668 as a model compound that contains structural elements that support potent ligand-induced inhibition of mutant ERs. We designed and synthesized a focused library of novel antagonists and probed how small and large perturbations in different ligand structural regions influenced inhibitory activity on individual mutant ERs in breast cancer cells. Effective inhibition derives from both nonpolar and moderately polar motifs in a multifunctional side chain of the antagonists, with the nature of the ligand core making important contributions by increasing the potency of ligands possessing similar types of side chains. Some of our new antagonists potently blocked the transcriptional activity of the three most common mutant ERs (L536R, Y537S, D538G) and inhibited mutant ER-mediated cell proliferation. Supported by our mol. modeling, these studies provide new insights into the role of specific components, involving both the ligand core and multifunctional side chain, in suppressing wild-type and mutant ER-mediated transcription and breast cancer cell proliferation.

Influence of lipid matrix composition on biopharmaceutical properties of lipid nanoparticles was written by Keck, Cornelia M.;Specht, David;Bruessler, Jana.

Lipid nanoparticles (LN) were invented in the early 1990ties and can be exploited for oral and topical drug delivery to increase the bioavailability of lipophilic active compounds The lipid matrix of the LN can be composed of solid lipids or of a mixture of liquid and solid lipids. The influence of the lipid matrix composition of LN on the dermal penetration efficacy is not known and was therefore investigated in this study. For this the whole spectrum of LN, that means NE (100% liquid lipid), SLN (100% solid lipid) and NLC that contained low, medium and high amounts of oil were produced and characterized in regard to size, zeta potential, crystallinity and in-vitro release. In addition, the dermal penetration efficacy was determined ex-vivo and the bio-phys. skin parameters, i.e., spreadability on skin, skin hydration, skin friction and transepidermal water loss were also assessed. Results demonstrate the tremendous influence of the lipid matrix composition on the biopharmaceutical properties of the LN but showed only minor differences in the physico-chem. properties of the particles. The physico-chem. properties of the LN and the in-vitro release data were not clearly linked to the dermal penetration efficacy, because also other parameters, e.g., skin hydration, spreadability of the formulation on skin and/or film formation of the LN on skin were found to be important parameters that influence the dermal penetration efficacy. Therefore, to allow for the development of effective LN formulations with tailor-made biopharmaceutical properties, not only the physico-chem. properties and in-vitro drug release profiles but also the most relevant biopharmaceutical properties of the LN should be assessed during the formulation development of LN.
