Zhang ZY, Li Y, Yu JH, Zhao JX, Yue JM. Lauinoids A-X: Labdane-type diterpenoids with anti-inflammatory activity from Croton laui. PHYTOCHEMISTRY 2024; 223:114138. [PMID: 38762154 DOI: 10.1016/j.phytochem.2024.114138] [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: 01/10/2024] [Revised: 05/08/2024] [Accepted: 05/12/2024] [Indexed: 05/20/2024]
Abstract
Croton laui (Euphorbiaceae) is a traditional medicinal plant used by the Li ethnic group in China to treat headaches, stomachaches, and diphtheria. To understand the pharmacological basis of its medicinal use, an extensive investigation of the ethanolic extract of the bark of C. laui was performed. After repeated chromatography, twenty-four undescribed labdane-type diterpenoids, lauinoids A-X (1-24), and five known analogs (25-29) were isolated. Their structures and absolute configurations were established using a combination of spectroscopic analyses, electronic circular dichroism, nuclear magnetic resonance calculations, and single-crystal X-ray diffraction. Among them, compounds 1-3 exhibited an 11(12 → 13)-abeo-16-nor-labdane skeleton, which originated putatively from 9 through a plausible pathway that involves a semipinacol rearrangement process. Compounds 11 and 12 belong to the rare class of 14,15-dinor-labdane diterpenoids. Compounds 18 and 28 exhibited substantial inhibitory effects by suppressing lipopolysaccharide-induced NO production in RAW 264.7 macrophages, with IC50 values of 3.37 ± 0.23 and 5.82 ± 0.28 μM, respectively. This study has greatly expanded the chemical diversity of labdane diterpenoids from C. laui and will guide future research on this ethnomedicinal plant.

[PMID: 34000366 DOI: 10.1016/j.jep.2021.114206] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Revised: 05/02/2021] [Accepted: 05/11/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Genus Sapium, belonging to Euphorbiaceae family, has a wide distribution in Asia and in temperate and tropical regions of Africa and America. The various parts of Sapium species have been used in traditional Chinese herbal medicine for the treatment of edema, skin-related diseases, bacterial infections, cancers, diabetes, and other ailments. AIM OF THE STUDY A comprehensive and updated review on the phytochemistry, pharmacology, and traditional medicinal uses of Sapium has been summarized and discussed to facilitate further exploitation of the therapeutic values of Sapium species. MATERIALS AND METHODS The relevant information of Sapium species was collected by scientific search engines including Elsevier, Google Scholar, Scifinder, and CNKI (China national knowledge infrastructure), and Master's dissertations and Summon from Shandong University Library. RESULTS Phytochemical studies revealed that approximately 259 compounds including terpenoids, phenylpropanoids, flavonoids, tannins, steroids, alkaloids, etc. have been isolated and identified from Sapium species, among which terpenoids, phenylpropanoids and tannins are the main constituents. Pharmacological in vitro and in vivo studies revealed that the extracts and pure compounds possessed significant antibacterial, antiinflammatory, antioxidant, antihypertensive effects, cytotoxicity, antidiabetic, molluscicidal effects. Terpenoids, phenylpropanoids, tannins, flavonoids, and alkaloids may be responsible for these activities. CONCLUSIONS The traditional uses, phytochemistry, and pharmacology described in this article demonstrated that the plants of Sapium genus possess many different types of compounds exhibiting wide range of biological activities, and they have high medicinal value and potential in the treatment of a variety of diseases. Detailed phytochemical studies have been conducted on only twelve species in the literature. More wide-ranging studies are still needed to explore this genus. Most of the existing bioactivity-related studies were implemented on crude extracts. More in-depth studies are necessary to reveal the links between the traditional uses and bioactivity in the future.

Abstract
Chemical fractionation of the ethanolic extract generated from the twigs and leaves of Sapium discolor led to the isolation and identification of four new macrocyclic diterpenoids including three members of the rare casbane family, sapidisins A-C (1-3), and an analog of the cembrane class, sapidisin D (4), a new 3,4-seco ent-kaurane diterpenoid (5), and 18 known phenolic compounds. Their structures were elucidated by comprehensive spectroscopic analyses especially 1D NMR (1)H-(1)H couplings and 2D NMR ROESY data. The discovery of 1-4 from S. discolor provides a clue for further study on the biogenetic evolution of the widely existent tigliane-type diterpenoids in the Sapium species.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Several species from the genus Sapium possess a broad range of medicinal properties and they have been used as traditional medicines by indigenous groups in several regions such as Malaysia, Africa, Southern China and Bolivia. Most of the species reported to possess therapeutic effects which are used for the treatment of skin-related diseases such as eczema and dermatitis, but they may also be used for overstrain, lumbago, constipation and hernia. Species of this genus are also used to treat wounds and snake bites. In addition, the saps/latex of Sapium glandulosum, Sapium indicum and Sapium sebiferum have/has toxic effects and are used as bird and fish poisons. This review discusses the current knowledge of the medicinal uses, phytochemistry, biological activities and toxicities of species from the genus Sapium to reveal their therapeutic potentials and gaps offering opportunities for future research. MATERIALS AND METHODS This review is based on a literature study of scientific journals and books from libraries and electronic sources, such as ScienceDirect, PubMed and ACS. RESULTS As many as 65 compounds are included in this review. They belong to different classes of compounds including flavonoids, terpenoids and several other types of compounds, such as alkaloids, phenolic acids and amides. The pharmacological studies revealed that various types of preparations, extracts and single compounds of species from this genus exhibited a broad spectrum of biological activities including antioxidant, antimicrobial, anti-inflammatory and cytotoxic activities. However, Sapium glandulosum, Sapium indicum and Sapium sebiferum were reported to possess toxic effects and Sapium sebiferum was found to contain phorbol esters acting as a tumor-promoting agent. CONCLUSION The genus Sapium consists of 23 accepted (high confidence) species. However, only very few of species have been phytochemically and pharmacologically studied. There is great potential to discover new chemical constituents from this genus because only a few species have been phytochemically investigated thus far. Only 27 compounds of 65 identified compounds have been studied for their biological activities. Several extracts and single compounds from this genus were reported to exhibit interesting biological activities such as antimicrobial, antioxidant and cytotoxic effects. Furthermore, the toxicity studies of some phorbol esters suggested that the compounds acted as potential tumor-promoting agents by stimulating protein kinase C. This is an interesting fact in which a plant with medicinal properties also possesses toxic effects as well. Therefore, more clinical studies on the toxicity of the extracts of the plants and the compounds isolated from this genus are also crucial to ensure their safety and to assess their eligibility for use as sources for modern medicines.

Abstract
Three tigliane-type diterpenoids named excoecafolins A-C and two daphnane-type diterpenoids named excoecafolins D and E, together with 13 known compounds, were isolated from the EtOAc extract of Excoecaria acerifolia Didr. Their structures were elucidated through the analysis of the spectroscopic data. The anti-HIV-1 activity evaluation of five of these compounds showed that four possessed moderate anti-HIV-1 activities with EC50 0.258, 0.036, 0.046, and 0.978 μM, SI >1,836.9, 431.1, 298.7, and >503.7, respectively. Additionally, the chemotaxonomic issue of the affinity correlation between Thymelaeceae and Euphorbiaceae is discussed based on the isolates.

Abstract
This review describes the major discoveries of structurally diverse and/or biologically significant compounds from plant resources in China, mainly from the traditional Chinese medicines (TCMs) since the establishment of our research group in 1999. In the past decade, a large array of biologically significant and novel structures has been identified from plant resources (or TCM) in our laboratory. The structural modification of several biologically important compounds led to more than 400 derivatives, some of which exhibited significantly improved activities and provided opportunities to elucidate the structure-activity relationship of the related compound class. These findings are important for drug discovery and help us understand the biological basis for the traditional applications of these plants in TCM.
