Nat Prod Res 2024; 38:3481-3487. [PMID: 37647092 DOI: 10.1080/14786419.2023.2252153] [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: 05/06/2023] [Revised: 08/10/2023] [Accepted: 08/22/2023] [Indexed: 09/01/2023]
Abstract
Extracts from leaves and stems of Thymelaea tartonraira (L.) All. growing in Tunisia were characterised for the presence of flavonoids and phenolic acids by LC-ESI-MS analysis. Twelve flavonoids and ten phenolic acids were detected for the first time in the aerial parts of this plant species, the most abundant compounds being gallic acid, kaempferol, catechin, chlorogenic acid, naringenin and acacetin. The extracts were subjected to in vitro antileishmanial, antifungal and cytotoxic assays, showing promising antileishmanial activity for the E6 dichloromethane extract from the stems (IC50 values of 1.12 ± 0.50 and 5.41 ± 1.84 µg/mL on L. donovani axenic and intramacrophagic amastigotes, respectively) at the level of the reference drug miltefosine for axenic model. No antifungal activity was observed against Candida albicans (CAAL) and Aspergillus fumigatus (ASFU) strains, with the exception of the E6 dichloromethane extract (IC50 value of 25.28 ± 4.89 µg/mL on CAAL93 strain). Low toxicity was also highlighted against macrophages Raw 264.7 cells. These promising results point out Thymelaea tartonraira (L.) All. extracts as a valuable source of new natural products to combat leishmaniasis.

Abstract
An efficient green approach for the trapping of in situ generated ortho-and para-quinone methide intermediates by imidazoles and pyrazoles has been developed. A wide range of quinone methide precursors based on simple phenols are compatible with the experimental protocol under mild thermal conditions. This methodology was demonstrated to be suitable for the synthesis of methylene-linked benzopyrone-azole hybrids using naturally occurring coumarin and chromone Mannich bases. In most cases, the products were isolated in good to excellent yields without chromatographic purification. In vitro studies showed that some of the synthesized compounds exhibit inhibitory activity towards α-glucosidase.

Cornulacin: a new isoflavone from Cornulaca monacantha and its isolation, structure elucidation and cytotoxicity through EGFR-mediated apoptosis. RSC Med Chem 2024:d4md00524d.

Abstract
Chemical investigation of the methanolic extract of Cornulaca monacantha (Amaranthaceae), an annual wild herb collected from North Sinai, Egypt, yielded a new isoflavone cornulacin 1 and five known compounds: N-trans-feruloyltyramine 2, N-trans-feruloyl-3'-methoxytyramine 3, N-trans-caffeoyl tyramine 4, Cannabisin F 5 and (2aS, 3aS) lyciumamide D 6. Using MTT assay, the isolated compounds were evaluated for their in vitro cytotoxicity against pancreatic (Panc1) and ovarian (A2780) cancer cell lines. Compounds 1, 2, 3, and 4 exhibited promising cytotoxic activity against the tested cells, among which compound 1 (IC50 of 2.1 ± 0.21 μM) was the most active one against A2780 cells, whereas compound 2 (IC50 of 3.4 ± 0.11 μM) was the most effective compound against Panc1 cells. Accordingly, compound 1 was further investigated for its apoptotic induction in A2780 cancer cells using Annexin V/PI staining. Compound 1 significantly stimulated apoptotic ovarian A2780 cancer cells by 45.9-fold and arrested cell proliferation in the S-phase. Such activity was mediated through the upregulation of proapoptotic genes Bax; P53; and caspase 3, 8, and 9 besides the downregulation of the Bcl-2 gene, the anti-apoptotic one. Furthermore, molecular docking investigation demonstrated the strong binding affinity of compound 1 with EGFR active sites, which validated its experimental EGFR enzyme inhibition activity.

MARINE ENVIRONMENTAL RESEARCH 2023; 186:105927.

Abstract
Microplastic pollution of the ocean has received extensive attention as plastic pollution increases globally, but the potential ecological risks caused by microplastic interactions with trace metals still require further research. In this study, Apostichopus japonicus was used to explore the individual and combined toxicities of cadmium (Cd) and microplastics and their effects on growth, Cd tissue accumulation, digestive enzymes, and gut microbes. The body weight gain and specific growth rate of animals exposed to a combination of high concentrations of Cd and microplastics decreased. The addition of high concentrations of cadmium to the diet led to an increase in cadmium content in the respiratory tree, digestive tract and body wall. Amylase, lipase and trypsin decreased to different degrees in the group treated with high concentrations of Cd/microplastics. Firmicutes were significantly reduced across multiple treatment groups, with the order Lactobacillales being the most significantly affected. Cd is the pollutant causing the greatest negative impact, but the presence of microplastics undoubtedly increases its toxicity.

New Specific α-Glucosidase Inhibitor Flavonoid from Thymelaea tartonraira Leaves: Structure Elucidation, Biological and Molecular Docking Studies. Chem Biodivers 2023; 20:e202200944. [PMID: 36757004 DOI: 10.1002/cbdv.202200944] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 02/01/2023] [Accepted: 02/01/2023] [Indexed: 02/10/2023]
Abstract
The phytochemical investigation of Thymelaea tartonraira leaves led to the isolation and characterization of six compounds, including one new flavonoid glycoside identified as hypolaetin 8-O-β-D-galactopyranoside (4) along with five known compounds, daphnoretin (1), triumbelletin (2), genkwanin (3), tiliroside (5) and yuankanin (6). Their structures were established based on spectroscopic methods, such as UV, IR, NMR, and HR-ESI-MS. Triumbelletin (2) and tiliroside (5) were isolated for the first time from T. tartonraira leaves. The antioxidant property of all isolated compounds was tested based on DPPH, FRAP and total antioxidant capacity assays. Compound 4 displayed an antioxidant potency more interesting than vitamin C with an IC50 =15.00±0.50 μg/ml, followed by compound 5. Furthermore, the both compounds 4 and 5 were tested for their α-amylase inhibitory activity in-vitro. Compound 4 displayed higher potency to inhibit α-amylase, with an IC50 =46.49±2.32 μg/ml, than compound 5, with an IC50 =184.2±9.2 μg/ml, while the reference compound acarbose presented the highest potency to inhibit α-amylase with an IC50 =0.44±0.022 μg/ml. Compound 4 displayed a strong inhibitory ability of α-glucosidase activity approximately twice more than the reference compound, acarbose, with IC50 values of 60.00±3.00 and 125.00±6.25 μg/ml, respectively. Thus, compound 4 exhibited a specific inhibitory activity for α-glucosidase. The molecular docking studies have supported our findings and suggested that compound 4 has been involved in various binding interactions within the active site of both enzymes α-amylase and α-glucosidase.

Abstract
Aeonium is a genus of succulents belonging to the Crassulaceae family. Their importance in traditional medicine has stimulated both pharmacological and chemical research. In this study, we optimized extraction, separation, and analytical conditions using a high performance liquid chromatographic method coupled with electrospray ionization mass spectrometry by the negative mode (HPLC-ESI-MS) in order to, for the first time, determine thirty-four compounds from Aeonium arboreum leaves. Twenty-one of them are assigned among which are sixteen flavonoids and five phenolic acids. FRAP, TAC, DPPH, and ABTS•+ radical scavenging were used to evaluate antioxidant activity. The obtained IC50 values ranged from 0.031 to 0.043 mg.mL−1 for DPPH and between 0.048 and 0.09 mg·mL−1 for ABTS•+. Antimicrobial activity was also assessed. The obtained minimum inhibitory concentrations (MIC) of these extracts ranged from 12.5 to 50 µg·mL−1 against Micrococcus luteus, Listeria ivanovii, Staphylococcus aureus, Salmonella enterica, Escherichia coli, Pseudomonas aeruginosa, Aspergillus niger, and Fusarium oxysporum, and from 25 to 50 µg·mL−1 against Candida albicans. Therefore, these extracts can be considered as a potential source of biological active compounds.
