[PMID: 39260588 DOI: 10.1016/j.phytochem.2024.114272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Revised: 08/29/2024] [Accepted: 09/05/2024] [Indexed: 09/13/2024]
Abstract
Phytochemical investigation of the whole plants of Helleborus niger L. (Ranunculaceae) resulted in the isolation of five undescribed compounds, including one bufadienolide (1), two bufadienolide rhamnosides (2 and 3), and two ecdysteroids (12 and 13), along with eight known compounds (4-11). The chemical structures of 1-3, 12, and 13 were determined by spectroscopic studies, including 2D NMR, and chromatographic and spectroscopic analyses of the hydrolyzed products. Compounds 1-13 were evaluated for their cytotoxic activity against HL-60 human leukemia cells, A549 human lung adenocarcinoma cells, SBC-3 human small-cell lung cancer cells, and TIG-3 human normal diploid lung cells. Compounds 1-12 showed cytotoxic activity against HL-60, A549, and SBC-3 cells, with IC50 values ranging from 0.0016 to 6.1 μM. Bufadienolide rhamnoside 2 exhibited potent cell proliferation inhibitory activity against SBC-3 cells after 24-48 h of treatment and apoptosis-inducing activity in SBC-3 cells via an intrinsic pathway after 72 h of treatment. The JFCR39 panel screening of 2 suggests that the molecular target of 2 is Na+,K+-ATPase.

Abstract
The genus Helleborus belongs to the Ranunculaceae family, distributed in southeastern Europe and western Asia. In folk medicine, it is commonly used as an anti-inflammatory and analgesic medicine for rheumatoid arthritis and bruises. Through reviewing recent articles, it was found that two hundred and twenty-six compounds have been isolated and identified from the genus Helleborus. These compounds include steroids, flavonoids, phenylpropanoids, lignans, anthraquinones, phenolics and others. Among them, the main chemical constituents are steroids. Pharmacological studies show Helleborus has anti-cancer, immunomodulatory, anti-inflammatory, analgesic, anti-hyperglycaemic, antioxidant and antibacterial properties. This article reviews the botany, phytochemistry, pharmacological effects and clinical applications of the genus Helleborus. Hopefully, it will provide a reference for in-depth research and exploitation of the genus Helleborus.

Steroidal saponins from the roots of Paris verticillata and their anti-proliferative and anti-inflammatory activities. PHYTOCHEMISTRY 2024; 218:113941.

Abstract
Thirteen previously undescribed steroidal saponins, named parisverticilloside A-M (1-13) and twenty known steroidal saponins (14-33) were isolated from ethanol extract of the roots of Paris verticillata. Their structures were identified by a series of spectroscopic methods, including 1D and 2D NMR, HR-ESI-MS, optical rotatory dispersion and chemical processes. The anti-proliferative activities of all compounds against LN229, HepG2, MDA-MB-231 and 4T1 cell lines were evaluated using the CCK8 assay with cisplatin or capecitabine as the positive control. The anti-inflammatory activities of all compounds were measured by inhibition of LPS-induced NO release from BV2 cell lines, with dexamethasone as the positive control.

Structure Elucidation of 16 Undescribed Steroidal Glycosides from the Underground Parts of Agapanthus africanus and Apoptosis-Inducing Activity in Small-Cell Lung Cancer Cell. ACS OMEGA 2023; 8:2808-2830.

Abstract
To explore new candidates for anticancer agents from natural products, the underground parts of Agapanthus africanus, commonly used as an ornamental plant, were investigated phytochemically. As a result, 16 undescribed steroidal glycosides (1-16) were obtained, and their structures were determined mainly by NMR spectroscopic analysis and chemical transformations. The cytotoxic activities of the isolated compounds (1-16) against SBC-3 human small-cell lung cancer cells, A549 human adenocarcinoma cells, and HL-60 human promyelocytic leukemia cells were evaluated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2-tetrazolium bromide (MTT) assay. Compound 1, a bisdesmosidic furostanol glycoside, and 10, a bisdesmosidic spirostanol glycoside, were cytotoxic to all three cell lines with IC50 values ranging from 1.2 to 13 μM. As 1 exhibited the most potent cytotoxicity against SBC-3 cells among the isolated compounds, its apoptosis-inducing activity toward SBC-3 cells was examined. Compound 1 arrested SBC-3 cells at the G2/M phase of the cell cycle and effectively induced apoptosis via an intrinsic pathway accompanied by the dissipation of membrane potential and morphological changes in mitochondria.

JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY 2021; 69:14568-14579.

Abstract
Twelve steroidal glycosides (1-12) were isolated from the aerial parts of Avena sativa L. (Poaceae). Among the isolated compounds, 1 was directly isolated from the plant for the first time, and 2-6 were new steroidal glycosides. The structures of 1-6 were determined by analysis of their spectroscopic data, chemical transformations, and chromatographic and spectroscopic analyses of the hydrolyzed products. Compounds 5 and 6 were novel steroidal glycosides with a B-ring contracted skeleton (B-nor steroid). Compounds 1, 9, 11, and 12 were cytotoxic to HL-60 human promyelocytic leukemia cells, MIA PaCa-2 human pancreatic carcinoma cells, and A549 human lung adenocarcinoma cells with IC50 values ranging from 0.79 to 13.5 μM. HL-60 cells treated with 1 exhibited apoptotic characteristics, namely, condensed nuclear chromatin, accumulation of sub-G1 cells, and activation of caspase-3. Additionally, the loss of the mitochondrial membrane potential and the release of cytochrome c into the cytoplasm in 1-treated HL-60 cells suggested that 1 induced apoptosis through a mitochondrial-dependent apoptotic pathway.
