Zheng X, Li L, Liu Z, Zou H, Zhou X. Study on the quality evaluation of the leaves of Croton tiglium from different regions based on quality markers. PHYTOCHEMICAL ANALYSIS : PCA 2024; 35:817-824. [PMID: 38279571 DOI: 10.1002/pca.3330] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 01/08/2024] [Accepted: 01/09/2024] [Indexed: 01/28/2024]
Abstract
METHODOLOGY The chemical constituents of LCT were identified and quantified using high-performance liquid chromatography with a diode array detector. A characteristic fingerprint was then established and combined with multivariate statistical analysis of 16 common peaks and eight diterpenoids to identify the quality markers. INTRODUCTION The leaves of Croton tiglium (LCT) have long been used in folk and ethnic medicine in China. Owing to the various regions, the chemical composition and content of LCT may differ, and hence, the quality of medicinal materials may be different. However, quality standards have not yet been established, although some studies have been conducted on their composition. OBJECTIVES To quantitatively compare the chemical constituents of LCT from different areas and establish a quality evaluation of LCT based on quality markers. RESULTS Eight quality markers selected based on 16 common peaks and three quality markers selected based on eight diterpenoids can distinguish LCT from three regions. The diterpenoids, including 12-O-acetylphorbol-13-(2-methylbutyrate) (3), 12-O-tiglyl-4-deoxy-4α-phorbol-13-acetate (6), and 12-O-(2-methyl)butyrylphorbol-13-tiglate (8), can be used as potential quality markers for the quality evaluation of LCT. CONCLUSION Diterpenoids are highly efficient markers for quality evaluation. This study provides robust identification data and lays the foundation for formulating quality standards for LCT.

[PMID: 38257314 PMCID: PMC10818740 DOI: 10.3390/molecules29020401] [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: 11/26/2023] [Revised: 12/30/2023] [Accepted: 01/10/2024] [Indexed: 01/24/2024] Open
Abstract
The leaves of C. tiglium have been comprehensively researched for their structurally novel bioactive natural compounds, especially those with anti-schistosomiasis liver fibrosis activity, because ethyl acetate extract, which can be extracted from the leaves of C. tiglium, has good anti-schistosomiasis liver fibrosis effects. One new tigliane-type diterpene, 20-acetyl-13-O-(2-metyl)butyryl-phorbol (1), and nine known (2-10) analogues were isolated from the leaves of C. tiglium. Their structures were elucidated on the basis of spectroscopic analysis and ECD analysis. All diterpenoids had a stronger insecticidal effect on schistosomula, and compounds 2, 4, and 10 had good anti-liver-fibrosis effects. Furthermore, compared with the model group, compound 2 significantly downregulated the protein and mRNA expression of COL-I, COL-III, α-SMA, and TGF-β1 on TGF-β1-induced liver fibrosis in LX-2 cells. Meanwhile, compound 2 also regulated the expression of TGF-β/Smad-pathway-related proteins. The results suggest that diterpenoids from C. tiglium may serve as potential schistosomula-killing and anti-liver-fibrosis agents in the future.

Abstract
Diterpenes represent a wider class of isoprenoids, with more than 18,000 isolated compounds, and are present in plants, fungi, bacteria, and animals in both terrestrial and marine environments. Here, we report on the fully characterised structures of 251 new diterpenes, isolated from higher plants and published from 2017, which are shown to have antitumoral activity. An overview on the most active compounds, showing IC50 < 20 μM, is provided for diterpenes of different classes. The most active compounds were extracted from 29 different plant families; particularly, Euphorbiaceae (69 compounds) and Lamiaceae (54 compounds) were the richest sources of active compounds. A better activity than the positive control was obtained with 33 compounds against the A549 cell line, 28 compounds against the MCF-7 cell line, 9 compounds against the HepG2 cell line, 8 compounds against the Hep3B cell line, 19 compounds against the SMMC-7721 cell line, 9 compounds against the HL-60 cell line, 24 compounds against the SW480 cell line, and 19 compounds against HeLa.

Abstract
Crotonianoids A-C (1-3), three unusual tigliane diterpenoids, were isolated from the seeds of Croton tiglium. Compound 1 is a 13,14:13,15-diseco-tigliane featuring a unique spiro[bicyclo[5.3.0]decane-2,5'-2'(3'H,4'H)-furanone] core; 2 is a 13,15-seco-tigliane incorporating a rare peroxide bridge between C-13 and C-15; and 3 is the first example of a phorbol ester with a 10R-configuration. Their structures were determined by spectroscopic, computational, and X-ray diffraction methods. Compounds 1 and 2 markedly inhibited the growth and survival of prostate cancer cell C4-2B at micromolar concentrations and induced cell apoptosis. Mechanistic study revealed that 1 and 2 could suppress androgen receptor (AR) signaling pathway by promoting the degradation of AR protein.

Abstract
Schedule E1 is an important part of Drugs and Cosmetics Act (Government of India) that comprises the list of poisonous drugs from plant, animal and mineral origins to be consumed under medical supervision. Ayurveda, the world's oldest medicinal system has a list of drugs represented in schedule E1 that are used since thousands of years. This review reports the anti-cancer activities of fifteen toxic ayurvedic drugs from plant origin represented in Drugs and Cosmetics Act, 1940. The information was collected from the various authentic sources, compiled and summarised. The plant extracts, formulations, phytoconstituents and other preparations of these drugs have shown effective activities against mammary carcinoma, neuroblastoma, non-small cell lung carcinoma, lymphocytic leukaemia, colorectal adenocarcinoma, Ehrlich ascites carcinoma, prostate adenocarcinoma, glioblastoma asterocytoma and other malignancies. They have various mechanisms of action including Bax upregulation, Bcl2 downregulation, induction of cell cycle arrest at S phase, G2/M phase, inhibition of vascular endothelial growth factors, inhibition of Akt/mTOR signalling etc. Certain traditional ayurvedic preparations containing these plants are reported beneficial and the possibilities of these drugs as the alternative and adjuvant therapeutic agents in the current cancer care have been discussed. The studies suggest that these drugs could be utilised in future for the critical care of malignancies.

Antibacterial and cytotoxic prenylated dihydrochalcones from Eriosema montanum. Fitoterapia 2021; 149:104809. [PMID: 33359421 DOI: 10.1016/j.fitote.2020.104809] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Revised: 12/17/2020] [Accepted: 12/17/2020] [Indexed: 12/17/2022]
Abstract
Two new prenylated dihydrochalcones (1,2) and eighteen known secondary metabolites (3-20) were isolated from the CH2Cl2-MeOH (1:1) extracts of the roots, the stem bark and the leaves of Eriosema montanum Baker f. (Leguminosae). The structures of the isolated compounds were characterized by NMR, IR, and UV spectroscopic and mass spectrometric analyses. The structures of compounds 5, 10, 11 and 13 were confirmed by single crystal X-ray diffraction. The antibacterial activity of the crude extracts and the isolated constituents were established against Gram-positive and Gram-negative bacteria. Among the tested compounds, 1-4 and 10 showed strong activity against the Gram-positive bacterium Bacillus subtilis with minimum inhibitory concentration (MIC) ranging from 3.1 to 8.9 μM, as did the leaf crude extract with an MIC of 3.0 μg/mL. None of the crude extracts nor the isolated compounds were active against Escherichia coli. Compounds 1, 3 and 4 showed higher cytotoxicity, evaluated against the human breast cancer cell line MCF-7, with EC50 of 7.0, 18.0 and 18.0 μM, respectively. These findings contribute to the phytochemical understanding of the genus Eriosema, and highlight the pharmaceutical potential of prenylated dihydrochalcones.
