Al-Mur BA. In vitro anticancer, antioxidant and antibacterial activities of crude extract prepared from Enteromorpha intestinalis habited in Jeddah, Saudi Arabia. Saudi J Biol Sci 2024; 31:104026. [PMID: 38840812 PMCID: PMC11152718 DOI: 10.1016/j.sjbs.2024.104026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Revised: 05/12/2024] [Accepted: 05/19/2024] [Indexed: 06/07/2024] Open
Abstract
The recent study purposes to evaluate the biological activities of Enteromorpha intestinalis gathered from Jeddah coastal area, Saudi Arabia, with respect to its phytochemical components. Our results indicated that the values of moisture content, ash, total organic matter, total proteins, total lipids and total carbohydrates were 34.25 ± 5.6 %, 40.70 ± 2.3 %, 25.05 ± 1.73 %, 14.39 ± 0.8 %, 4.86 ± 6.9 % and 2.81 ± 1.4 %, respectively. The data also showed that the total phenols and flavonoids were 345.04 ± 1.50 and 320.67 ± 0.92 mg/g in the dried sample, respectively. Furthermore, four compounds were detected by HPLC at very low concentrations (quinic acid, ellagic acid, cinnamic acid, and phenanthrene) and flavonoids data confirmed the presence of apeginin, rudin, diosmin, and quercilin at high concentrations of 141.26, 11.42, 121.75, and 145.28. mg/g, respectively. The crude extract of Enteromorpha intestinalis exhibited cytotoxicity toward hepatocellular carcinoma cells (HepG-2 cell line) using an MTT assay with concentration range between 2 and 500 µg/mL for 48 h with IC50 = 40.02 ± 3.94 µg/mL. Evidently, the Enteromorpha intestinalis extract had Hepatoprotective activity with IC50 = 447.31 ± 14.59 μg/mL. The IC50 activity of a crude methanol extract of Enteromorpha intestinalis was compared with that of an antioxidant drug (Torolox). The value (98.82 ± 1.30 μg/mL) was recorded close to Torolox (62.4 ± 0.70 μg/mL). This extract also possessed moderate antibacterial activity with inhibition zones ranging between 10 mm against Pseudomonas aeruginosa to 16 mm against Escherichia coli. Green seaweed, along with other types of seaweed, has received significant attention in recent years. Despite their potential benefits, green seaweeds are underutilized in many parts of the world. Extensive studies on different green seaweed isolates and extracts are necessary.

[PMID: 38513575 DOI: 10.1016/j.intimp.2024.111897] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Revised: 03/05/2024] [Accepted: 03/16/2024] [Indexed: 03/23/2024]
Abstract
BACKGROUND Esculin, a main active ingredient from Cortex fraxini, possesses biological activities such as anti-thrombosis, anti-inflammatory, and anti-oxidation effects. However, the effects of Esculin on septic cardiomyopathy remains unclear. This study aimed to explore the protective properties and mechanisms of Esculin in countering sepsis-induced cardiac trauma and dysfunction. METHODS AND RESULTS In lipopolysaccharide (LPS)-induced mice model, Esculin could obviously improve heart injury and function. Esculin treatment also significantly reduced the production of inflammatory and apoptotic cells, the release of inflammatory cytokines, and the expression of oxidative stress-associated and apoptosis-associated markers in hearts compared to LPS injection alone. These results were consistent with those of in vitro experiments based on neonatal rat cardiomyocytes. Database analysis and molecular docking suggested that TLR4 was targeted by Esculin, as shown by stable hydrogen bonds formed between Esculin with VAL-308, ASN-307, CYS-280, CYS-304 and ASP-281 of TLR4. Esculin reversed LPS-induced upregulation of TLR4 and phosphorylation of NF-κB p65 in cardiomyocytes. The plasmid overexpressing TLR4 abolished the protective properties of Esculin in vitro. CONCLUSION We concluded that Esculin could alleviate LPS-induced septic cardiomyopathy via binding to TLR4 to attenuate cardiomyocyte inflammation, oxidative stress and apoptosis.

Abstract
In addition to hemostasis and thrombosis, blood platelets are involved in various processes such as inflammation, infection, immunobiology, cancer metastasis, wound repair and angiogenesis. Platelets' hemostatic and non-hemostatic functions are mediated by the expression of various membrane receptors and the release of proteins, ions and other mediators. Therefore, specific activities of platelets responsible for the non-hemostatic disease are to be inhibited while leaving the platelet's hemostatic function unaffected. Platelets' anti-aggregatory property has been used as a primary criterion for antiplatelet drugs/bioactives; however, their non-hemostatic activities are not well known. This review describes the hemostatic and non-hemostatic function of human blood platelets and the modulatory effects of bioactive food components. PRACTICAL APPLICATIONS: In this review, we have discussed the antiplatelet effects of several food components. These bioactive compounds inhibit both hemostatic and non-hemostatic pathways involving blood platelet. Platelets have emerged as critical biological factors of normal and pathologic vascular healing and other diseases such as cancers and inflammatory and immune disorders. The challenge for therapeutic intervention in these disorders will be to find drugs and bioactive compounds that preferentially block specific sites implicated in emerging roles of platelets' complicated contribution to inflammation, tumour growth, or other disorders while leaving at least some of their hemostatic function intact.

Abstract
In this research, Fe3O4@SiO2@KCC-1@MPTMS@CuII as a new cockscomb flower-like mesoporous nanocomposite was prepared and characterized by various techniques including Fourier transform infrared (FT-IR) spectroscopy, powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), SEM-based energy-dispersive X-ray (EDX) spectroscopy, inductively coupled plasma-optical emission spectrometry (ICP-OES), thermogravimetric analysis/differential thermal analysis (TGA/DTA), vibrating sample magnetometry (VSM), UV-Vis spectroscopy, and Brunauer-Emmett-Teller (BET) and Barrett-Joyner-Halenda (BJH) analyses. The as-prepared Fe3O4@SiO2@KCC-1@MPTMS@CuII mesoporous nanocomposite exhibited satisfactory catalytic activity in the reduction and reductive acetylation of nitroarenes in a water medium and solvent-free one-pot synthesis of some coumarin compounds including 3,3'-(arylmethylene)bis(4-hydroxy-2H-chromen-2-ones) (namely, bis-coumarins) (3a-n) and 2-amino-4-aryl-7,7-dimethyl-5-oxo-5,6,7,8-tetrahydro-4H-chromene-3-carbonitriles (6a-n) along with acceptable turnover numbers (TONs) and turnover frequencies (TOFs). Furthermore, the mentioned CuII-containing mesoporous nanocatalyst was conveniently recovered by a magnet from reaction environments and reused for at least seven cycles without any significant loss in activity, which confirms its good stability.

[PMID: 35164411 PMCID: PMC8839657 DOI: 10.3390/molecules27031146] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 02/04/2022] [Accepted: 02/05/2022] [Indexed: 12/28/2022]
Abstract
Flavonoids are compounds with a benzopyranic structure that exhibits multiple pharmacological activities. They are known for their venotonic activity, but their mechanism of action remains unclear. It is thought that, as this mechanism is mediated by prostaglandins, these compounds may interfere with the arachidonic acid (AA) cascade. These assays are designed to measure the antiplatelet aggregation capacity of quercetin, rutin, diosmetin, diosmin, and hidrosmin, as well as to evaluate a potential structure−activity ratio. In this paper, several studies on platelet aggregation at different concentrations (from 0.33 mM to 1.5 mM) of different flavone compounds are conducted, measuring platelet aggregation by impedance aggregometry, and the cyclooxygenase (COX) activity by metabolites generated, including the activity of the pure recombinant enzyme in the presence of these polyphenols. The results obtained showed that quercetin and diosmetin aglycones have a greater antiplatelet effect and inhibit the COX enzyme activity to a greater extent than their heterosides; however, the fact that greater inhibition of the pure recombinant enzyme was achieved by heterosides suggests that these compounds may have difficulty in crossing biological membranes. In any case, in view of the results obtained, it can be concluded that flavonoids could be useful as coadjuvants in the treatment of cardiovascular pathologies.
