The pharmacological properties of Gypsophila eriocalyx: The endemic medicinal plant of northern central Turkey.

The aim of this study is to evaluate and compare the biological properties of different extracts (methanol, ethanol, and water) obtained from Gypsophila eriocalyx (G. eriocalyx), a medicinal plant traditionally used in Turkey. The components of different extracts were defined using the GC-MS method. The effects of G. eriocalyx extracts on cell proliferation, apoptosis, and cell cycle arrest in MDA-MB-231 breast cancer as well as in vitro antioxidant, enzyme inhibition, and antimicrobial activities were investigated. In accordance with the results obtained, although ethanol and methanol extracts of G. eriocalyx show higher antioxidant activity than G. eriocalyx water extract, enzyme inhibition activities of the extracts were not found to be significant compared to the reference drug. The methanol and ethanol extract of G. eriocalyx exhibited moderate antimicrobial activity against Staphylococcus aureus and methanol extract showed significant antimicrobial activity against Bacillus cereus. In addition, both extracts significantly inhibited cell viability in a dose-dependent manner in breast cancer cells. The cell growth inhibition by methanol and ethanol extracts induced S phase cell-cycle arrest and apoptosis in MDA-MB-231 cells. Lastly, in order to compare the activities of the chemicals found in Gypsophila eriocalyx plant extract, their activities against various proteins that are breast cancer protein (PDB ID:1A52 and 1JNX), antioxidant protein (PDB ID: 1HD2), AChE enzyme protein (PDB ID: 4M0E), BChE enzyme protein (PDB ID: 5NN0), and Escherichia coli protein (PDB ID: 4PRV)were compared. Then, ADME/T analysis calculations were made to examine the effects of molecules with high activity on human metabolism. Eventually, G. eriocalyx is thought to be a potent therapeutic herb that can be considered as an alternative and functional therapy for the management of diseases of a progressive nature related to oxidative damage such as infection, diabetes, cancer, and Alzheimer's disease.

Investigation on the mechanisms by which the herbal remedies induce anti-prostate cancer activity: uncovering the most practical natural compound.

Prostate cancer (PCa) is one of the most reported cancers among men worldwide. Targeting the essential proteins associated with PCa could be a promising method for cancer treatment. Traditional and herbal remedies (HRs) are the most practical approaches for PCa treatment. Here, the proteins and enzymes associated with PCa were determined based on the information obtained from the DisGeNET database. The proteins with a gene-disease association (GDA) score greater than 0.7 and the genes that have a disease specificity index (DSI) = 1 were selected as the target proteins. 28 HRs with anti-PCa activity as a traditional treatment for PCa were chosen as potential bioactive compounds. More than 500 compound-protein complexes were screened to find the top-ranked bioactives. The results were further evaluated using the molecular dynamics (MD) simulation and binding free energy calculations. The outcomes revealed that procyanidin B2 3,3'-di-O-gallate (B2G2), the most active ingredient of grape seed extract (GSE), can act as an agonist for PTEN. PTEN has a key role in suppressing PCa cells by applying phosphatase activity and inhibiting cell proliferation. B2G2 exhibited a considerable binding affinity to PTEN (11.643 kcal/mol). The MD results indicated that B2G2 could stabilize the key residues of the phosphatase domain of PTEN and increase its activity. Based on the obtained results, the active ingredient of GSE, B2G2, could play an agonist role and effectively increase the phosphatase activity of PTEN. The grape seed extract is a useful nutrition that can be used in men's diets to inhibit PCa in their bodies.Communicated by Ramaswamy H. Sarma.

In vitro anticancer, antioxidant and enzyme inhibitory potentials of endemic Cephalaria elazigensis var. purpurea with in silico studies.

In this study, the therapeutic potential and phytochemical composition of ethanolic extract of Cephalaria elazigensis var. purpurea (CE), an endemic species, were investigated. For this purpose, the antiproliferative effect of CE on the MCF-7 human breast cancer cell line was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, and its effectiveness on colony formation and cell migration was analyzed with clonogenic assay and wound healing assay, respectively. In addition, the cell death detection ELISA (CDDE) assay was conducted to determine the pro-apoptotic capacity of CE. The IC50 value of the CE was determined as 324.2 ± 14.7 µg/mL. Furthermore, upon 1000 µg/mL CE treatment, there was 4.96-fold increase in the population of cells undergoing apoptosis compared to the untreated control cells. The antioxidant activity tests were performed by DPPH free radical, ABTS cation radical, ferric-ion reducing power (FRAP) and ferrous-ion chelating power (FCAP) assays. Antioxidant activity values for the DPPH, ABTS and FRAP assays were found to be 125.6 ± 6.3, 34.09 ± 0.1 and 123.4 ± 4.2 µmol TE/mg DE, respectively. We further determined the effect of CE ethanolic extract against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) enzymes. CE plays an effective inhibitory role in AChE and BuChE (AChE: IC50: 10.54 µg/mL, BuChE: IC50: 6.84 µg/mL) respectively. Further, molecular docking stuy was conducted to understand the nature of the all compound against AChE an BChE. It is revealed that α-Linolenic acid shows lowest binding energy (-7.90 kcal/mol) towards AChE, on the other side, Linoleic acid shows good binding affinity (-7.40 kcal/mol) for BChE.Communicated by Ramaswamy H.
