Pharmacological potential of Jussiaea repens L. against CuSO 4 and bacterial lipopolysaccharide O55:B5 induced inflammation using in-vivo zebrafish models. JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116932. [PMID: 37473823 DOI: 10.1016/j.jep.2023.116932] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 07/11/2023] [Accepted: 07/17/2023] [Indexed: 07/22/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The Northeastern state of India is known for its remarkable biodiversity and untapped medicinal resources. Jussiaea repens L., commonly known as water primrose, is a plant found in this region that has been traditionally used by indigenous communities for various purposes. It has been employed to treat skin ulcerations, bone fractures, rheumatism, stomach pain, and intestinal worms. Despite its long-standing ethnopharmacological usage, there is limited scientific research on the bioactivity of Jussiaea repens L. However, preliminary studies have shown its potential antioxidant properties and cytotoxicity against cancer cells. Further exploration of its medicinal properties, particularly its potential as an anti-inflammatory agent, is warranted. AIM OF THE STUDY This study aimed to investigate the anti-inflammatory properties of Jussiaea repens L., a plant species found in the biodiverse Northeastern region of India. The plant has been traditionally used by indigenous communities for various ailments. By utilizing zebrafish as an animal model and evaluating its effects in different inflammation models, the study aimed to uncover the plant's potential as an anti-inflammatory agent. The research contributes to the scientific understanding of this traditional remedy and its potential therapeutic applications. METHODS Jussiaea repens L. extract was obtained from the stem and leaves using methanol as the solvent. Zebrafish embryos were used for in vivo assays. The anti-inflammatory study included two models: CuSO4-induced inflammation and tail wounding followed by bacterial lipopolysaccharide-induced inflammation. The activities of catalase (CAT) and superoxide dismutase (SOD) were measured in CuSO4-induced inflammation. Leukocyte migration at the injury site was observed in the tail wounding model. The extract's inhibition of the 15-LOX enzyme was assessed. All procedures followed established protocols and ethical guidelines. RESULTS AND CONCLUSION Jussiaea repens L. extract exhibited anti-inflammatory activity in two in vivo zebrafish models: CuSO4-induced inflammation and tail wounding combined with bacterial lipopolysaccharide-induced inflammation. The extract reduced mortality rates and showed antioxidant effects by increasing catalase (CAT) and superoxide dismutase (SOD) activities in the CuSO4 model. In the tail wounding model, the extract reduced leukocyte migration in a concentration-dependent manner. Additionally, the extract demonstrated dose-dependent inhibition of the 15-LOX enzyme in the in vitro assay. These results suggest that Jussiaea repens L. extract possesses anti-inflammatory properties and inhibits the 15-LOX enzyme.

Abstract
Potentilla sischanensis Bunge ex Lehm. is a widespread perennial herb in north China. The plant has little yellow flowers, and the petioles are white-tomentose and sparsely villous. To determine the chloroplast genome, total genomic DNA was extracted from fresh leaves and sequenced. The complete chloroplast genome was assembled and annotated. The chloroplast genome of this plant is a circular form with a length of 156,240 bp, including a large single-copy region (LSC, 85,748 bp), a small single-copy region (SSC, 18,566 bp), and two inverted repeats (IRs, 25,963 bp). A total of 132 genes were predicted, comprising 87 encoded proteins, 8 rRNAs and 37 tRNAs. The evolutionary history indicates that P. sischanensis was grouped within Potentilla and formed a clade with Potentilla chinensis and Potentilla stolonifera with a 100% bootstrap support value. The complete cp genome can serve as a reference for future studies on molecular biology, evolution, population genetics, taxonomy and resource protection.

Abstract
The viral particle, SARS-CoV-2 is responsible for causing the epidemic of Coronavirus disease 2019 (COVID-19). To combat this situation, numerous strategies are being thought for either creating its antidote, vaccine, or agents that can prevent its infection. For enabling research on these strategies, several target proteins are identified where, Spike (S) protein is of great potential. S-protein interacts with human angiotensin-converting-enzyme-2 (ACE2) for entering the cell. S-protein is a large protein and a portion of it designated as a receptor-binding domain (RBD) is the key region that interacts with ACE2, following to which the viral membrane fuses with the alveolar membrane to enter the human cell. The hypothesis is to identify molecules from the pool of anticancer phytochemicals as a lead possessing the ability to interact and mask the amino acids of RBD, making them unavailable to form associations with ACE2. Such a molecule is termed as 'fusion inhibitor'. We hypothesized to identify fusion inhibitors from the NPACT library of anticancer phytochemicals. For this, all the molecules from the NPACT were screened using molecular docking, the five top hits (Theaflavin, Ginkgetin, Ursolic acid, Silymarin and Spirosolane) were analyzed for essential Pharmacophore features and their ADMET profiles were studied following to which the best two hits were further analyzed for their interaction with RBD using Molecular Dynamics (MD) simulation. Binding free energy calculations were performed using MM/GBSA, proving these phytochemicals containing anticancer properties to serve as fusion inhibitors.Communicated by Ramaswamy H. Sarma.

Mitigation of X-ray induced DNA damages and expression of DNA-repair genes by antioxidative Potentilla fulgens root extract and its ethyl-acetate fraction in mammalian cells. Mutagenesis 2021; 36:165-175. [PMID: 33693790 DOI: 10.1093/mutage/geab009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2020] [Accepted: 03/04/2021] [Indexed: 11/13/2022] Open
Abstract
Potentilla fulgens is a medicinal plant in North-East India whose root is reported to have anti-diabetic, anticarcinogenic and antioxidant properties. The potential of hydro-alcoholic extract of P. fulgens root (PRE) for providing protection to mammalian cells exposed to ionising radiation was investigated in this study. The methanolic extract of PRE shows an enhanced radical scavenging ability in a concentration dependent manner. PRE-pre-treatment to stimulated human blood lymphocytes (HBLs) reduced the frequency of deletion and exchange aberrations induced by X-irradiation. Similar protection of chromosome aberrations was also observed in mouse bone marrow cells (BMCs) where mice were given PRE extract (1 mg extract/day/mice) ad libitum in the drinking water for 45 days before whole-body X-irradiation. Of the various extracts prepared by partitioning of the methanol extract, the ethyl-acetate (EA) fraction was found to possess better antioxidant, radical scavenging and DNA-damage reduction activities. PRE-pre-treatment also reduced the radiation-induced cell-cycle delay effectively in HBL. In HEK-293 cells, PRE reduced radiation-induced G2-block in cell kinetics. Interestingly, PRE-treatment alone increased the concentration of endogenous glutathione (GSH) in mouse BMC and in stimulated HBL along with the elevated expression of γ-glutamyl-cysteine synthetase heavy/catalytic subunit, a key determinant of GSH synthesis. Studies on expression of two DNA-repair genes revealed that there was a marked increase in the expression of GADD45 and H2AX genes after X-irradiation in stimulated HBL, and such expression was reduced significantly if PRE-treatment was given prior to radiation. The present findings show the ability of PRE to reduce radiation-induced DNA damages probably by free radical scavenging whereas modulation of expression of DNA-repair genes' and endogenous GSH-increment emerge as effective strategies. The present study is the first report on the selected medicinal plant species that suggests it to be a potential natural radioprotector when used as root extract or its EA fraction for mitigating radiation toxicity.
