This study provides confirmatory evidence for the anti-allodynic activity of purified 1 and also reveals two additional active iridoids from Viticis Fructus. These three iridoids could be potential candidates for the treatment of CIPN.Peroxisome proliferator-activated receptors-γ (PPAR-γ), a ligand-activated transcription factor, activated by several ligands like fatty acids (linoleic acid being the most common) or their metabolites, can function as potential therapeutic target for various cancers. Although various synthetic ligands, thiazolidinediones (TZDs), serves as full agonist for PPAR-γ, application of these molecules has been discontinued due to adverse toxicity profile. Hence, with a dire need to identify novel PPAR-γ-agonists, the present in silico study aimed to determine the effectiveness of potent flavonoids, kaempferol (CID 5280863), quercetin (CID 5280343), and stilbenoid resveratrol (CID 445154) and their 806 derivatives towards PPAR-γ that could combat the deleterious effect of TZDs. The molecular docking experiment performed by FlexX elucidated the efficacy of derivatives; Kem204, Qur8, and Res183 of kaempferol, quercetin, and resveratrol respectively to be more effective against PPAR-γ as compared with other derivatives. The physicochemical and pharmacokinetic parameters of Kem204, Qur8, and Res183 follow the drug-likeness and thus comprise a pharmacologically active model to be considered for advancing further potential hits. Further molecular dynamics (MD) simulation study revealed the Qur8 compound to have favorable dynamic interactions within the PPAR-γ which certainly paves away in developing futuristic potential anticancer drugs.

Colon cancer cells can migrate and metastasize by undergoing epithelial-to-mesenchymal transition (EMT). Mesenchymal stem cells (MSCs) are non-cancerous, multipotent adult stem cells, which can also migrate. In this study, we wanted to compare the biological, physical, and functional properties of these migratory cells.

HT-29 and HCT-116, two human colon carcinoma cell lines, represent less aggressive and more aggressive cancer cells, respectively. MSCs were isolated from human bone marrow. After confirming the identity of all the cell types, they were evaluated for E-cadherin, β1-integrin, Vimentin, ZEB-1, β-catenin, and 18SrRNA using Q-PCR. MMP-2 and MMP-9 activity were evaluated using gelatin zymography. Functional tests like wound healing assay, migration assay, and invasion assay were also done. Biomechanical properties like cell stiffness and non-specific adhesion (between indenter probe and cell membrane) were evaluated through nanoindentation using atomic force microscopy (AFM).

Expression of EMT and stem cell markers showed typical expression patterns for HT-29, HCT-116, and MSCs. Functional tests showed that MSCs migrated faster than malignant cells. MMP-2 and MMP-9 activity reinforced this behavior. Interestingly, the migration/invasion capacity of MSCs was comparable to aggressive HCT-116, and more than HT-29. MSCs also showed the maximum cell stiffness and non-specific cell-probe adhesions, followed by HCT116 and HT29 cells.

Our findings indicate that the migratory properties of MSCs is comparable or even greater than that of cancer cells and despite their high migration potential, they also have the maximum stiffness.

The inhibitory activity of an ethyl acetate extract of its fermentation broth was higher than that of an n-butanol extract. After isolation and purification, 9 compounds were obtained cyclo(L-Leu-L-Pro) (1), cyclo(L-Pro-L-Tyr) (2), Brevianamide F (3), 2-(3-Indolyl) ethanol (4), N-[2-(1H-indol-3-yl) ethyl] acetamide (5), 3, 3-di(1H-indol-3-yl)propane-1,2-diol (6), Lincomycin B (7), dibutylphthalate (8), and p-hydroxyphenethyl alcohol (9). Compounds 1, 5, and 9 showed inhibitory activities against potato virus Y (PVY). Compounds 1, 4, and 9 had significant inhibitory activity against genes HC-pro, P3, and Nib, compound 5 against gene P3, and compounds 1 and 4 against NIa. Compounds 1, 4, 5, and 9 had significant inhibitory activity against genes VPg and 6K1. Active compounds 1, 5, and 9 had various effects on the expression of viral genes related to pathogenesis. Expression of genes cullin and XTH was up-regulated and CP was down-regulated, compared to the positive control. In conclusion, compounds 1, 5, and 9 might be considered as potential antiviral agents for future development.Two environmentally friendly innovative extraction techniques - subcritical water (SWE) and microwave-assisted extraction (MAE) were applied for the extraction of phenolics from pomegranate peel. The impact of process conditions (SWE temperature 100-220 °C, extraction time 5-30 min; MAE solvent water and 50% ethanol, irradiation power 470 and 800 W) on the quality of extracts in terms of the content of total phenolics, total flavonoids, major phenolic constituents (gallic acid, ellagic acid, punicalin, punicalagin), as well as 5-hydroxymethylfurfural(HMF) amount was investigated. For SWE, temperature of 130 °C and 20 min extraction time were found optimal for obtaining high content of bioactive compounds and minimizing the yield of HMF. During MAE, phenolic compounds were effectively extracted by using lower microwave power and 50% ethanol. Comparing two techniques, MAE is more efficient than SWE for the extraction of phenolics from pomegranate peel while obtaining a HMF-free extracts.Cinnamomum cassia Presl. (CCP) is a popular natural spice possessing various pharmacological properties. We obtained polyphenol-rich fraction (CCP-P) from CCP by bioactivity-oriented purification method and evaluated its Wnt signaling inhibition activity. Firstly, the phenolic components were identified as the main bioactive compounds with anti-colorectal cancer activity. Then, we compared the anti-colorectal cancer activity of CCP extract obtained from different solvent by cell morphology alteration and EdU assay. Ethanol extract showed higher antiproliferative activity compared to water extract on HCT116 cells, with proliferating cells reducing to 41.12 and 21.83% at 156.00 μg GAE/mL, respectively. Next, separation and enrichment of polyphenols from ethanol extract was performed on AB-8 macroporous resins under optimal conditions. this website Further evaluation of the CCP-P bioactivity revealed that it exerted more potent antiproliferative activity on RKO and HCT116 cells, showing higher selectivity for Wnt-dependent colorectal cancer cells (CRCs).
