Abstract:

Daphnauranins C–E (compounds 1–3), two sesquiterpenoids and one monoterpenoid were isolated from the roots of Daphne aurantiaca Diels. Daphnauranin C is a 9-O-13 etherified and hydroperoxy-substituted guaiane sesquiterpenoid, daphnauranin D is a guaiane sesquiterpenoid ketal, and daphnauranin E is a monoterpenoid lactone. Their structures were elucidated by comprehensive analyses of MS, 1D NMR, and 2D NMR spectroscopic data. In an anti-feeding activities test, daphnauranins C–E showed activity against male fruit fly with anti-feeding indexes (AI) up to 39.1, 39.2, and 27.8% respectively, at 1 mM.

Abstract:

Two new guaiane derivatives (1 and 2) along with six known sesquiterpenoids (3-8) were isolated from the gorgonian Menella woodin. Their structures were elucidated by ID and 2D NMR and HRESIMS data as well as by comparison of their spectra with those in the literature. Relative configurations of asymmetric centers in 1 and 2 were suggested on the basis of NOESY and ID NOE correlations, absolute stereochemistry of these compounds was proposed in result of comparison of calculated (for both enatiomers) and experimental ECD. Some suggestions were made regarding a biosynthesis of guaiane sesquiterpenoids in this species. All the compounds were firstly isolated from M woodin.

Abstract:

This study investigated the protective effects of guaiane-type sesquiterpenoids isolated from Dendranthema morifolium (Ramat.) S. Kitam ﬂowers on lipopolysaccharide (LPS)-induced injury in H9c2 cardiomyocyte. Cell viability was determined by thiazolyl blue tetrazolium bromide (MTT). The content of released tumor necrosis factor alpha (TNF- α) and interleukin 6 (IL-6) was evaluated by enzyme-linked immunosorbent assay. The levels of lactate dehydrogenase (LDH) and creatine phosphate kinase (CK) were measured by using commercial available kits. The protein expression levels of pelF2 α, GRP78, Bax, caspase-3, caspase-9, Bcl-2, LC3-II, and p62 were measured by in-cell Western. Flow cytometry was used to detect H9c2 cardiomyocyte apoptosis. Compounds 5, 7, 1, 8, and 2 exhibited the effects of cardioprotection and activity sequence enhancement. The levels of IL-6, TNF- α, LDH, CK, pelF2 α, GRP78, Bax, caspase-3, caspase-9, p62, and H9c2 cardiomyocyte apoptosis were increased in LPS-treated H9c2 cardiomyocyte, while those of Bcl-2 and LC3-II were decreased. These effects could be effectively reversed by compounds 5, 7, 1, 8, and 2. Results demonstrated that the guaiane-type sesquiterpenoids could prevent LPS-induced injury in cardiomyocyte by decreasing endoplasmic reticulum (ER) stress, apoptosis, and autophagy as well as downregulating the inflammatory mediators. In addition, the active groups of guaiane-type sesquiterpenoids might be the angelate at C-8 and the exocyclic double bond at C-11.

Abstract:

Retusone A (1), a new sesquiterpene dimer consisting of two guaiane-type sesquiterpenoids, and oleodaphnal (2) were isolated from heartwood of Wikstroemia retusa (Thymelaeaceae). The planar structure of 1 was elucidated on the basis of HRESIMS and NMR spectroscopic data, and the relative stereochemistry was established by X-ray diffraction analysis. The absolute configuration of 1 was determined by electronic circular dichroism. Compound 1 suppressed luciferase reporter gene expression driven by the HBO1 (histone acetyltransferase binding to ORC1) gene promoter in human breast cancer MCF7 cells. Compound 1 also decreased the expression of endogenous HBO1 mRNA and protein, and inhibited proliferation of the cells. These results suggest that retusone A (1), which has a unique dimeric sesquiterpenoid structure with inhibitory activity against HBO1 expression, may contribute to the development of a novel therapeutic candidate for the treatment of breast cancer.

The structures of the new metabolites were elucidated by spectroscopic analysis, including one-dimensional (1D) and two-dimensional (2D) Nuclear Magnetic Resonance (NMR) and high-resolution electrospray ionization mass spectrometry (HR-ESIMS). The antimicrobial properties of 1–9 were screened against seven different pathogenic microbes, and compounds 1–3 showed a potent antifungal activity.

Abstract:

Two new guaiane sesquiterpenes, aquisinenoids A and B (1 and 2), two new eudesmane-type sesquiterpenoids, aquisinenoids C and D (3 and 4), one new cucurbitacin, aquisinenoid E (5), and five known cucurbitacins (6–10) were isolated from agarwood of Aquilaria sinensis. The structures of these new compounds, including their absolute configurations, were characterized by spectroscopic and computational methods. The biological evaluation showed that compounds 3 and 9 had an anti-cancer effect on most of the cancer cells at 5 μM, especially in human breast cancer cells. Interestingly, the new compound 3 exhibited more sensitivity on cancer cells than normal cells, highlighting its potential as a novel anti-cancer agent. Mechanically, compound 3 treatment increased the ROS generation and triggered apoptosis of human breast cancer cells.

Abstract:

Alisma orientale (Sam.) Juzep. (Alismataceae) is a traditional and famous Chinese medicinal herb. Its rhizomes, which possess versatile bioactivities, are commonly used to treat oliguria, edema, gonorrhea with turbid urine, leukorrhea, diarrhea and dizziness. Approximately 120 compounds have been isolated from A. orientale. Terpenoids have been identified as A. orientale’s characteristic constituents, which include protostane triterpenoids and guaiane sesquiterpenoids. The traditional medical uses of A. orientale in TCM have been evaluated in modern pharmacological studies, which have shown that A. orientale and its active constituents exhibit a wide range of bioactivities, such as diuretic, anti-urolithiatic, antinephritic, anti-atherosclerotic, immunomodulatory, and hepatoprotective activities. The medicinal potential of A. orientale makes it an ideal candidate for new drug development. Further studies are still required to identify its bioactive constituents, and elucidate the structure–activity relationship and detailed mechanisms of action. Additionally, the use of the other medicinal parts of A. orientale may reduce resource waste and afford novel secondary metabolites.

Abstract:

Jungia sellowii (Asteraceae) is a shrub that grows in Southern Brazil and polar extract of its leaves presents anti-inflammatory properties. Cyperane, guaiane, nortrixane, and trixane sesquiterpene types were reported as the main metabolites in Jungia species. This work aims to describe the isolation and identification of sesquiterpenes in the leaves of J. sellowii using liquid–liquid partition and centrifugal partition chromatography. Thus, the crude extract of fresh leaves of J. sellowii was partitioned with hexane, dichloromethane, ethyl acetate and butanol, respectively. The butanol fraction was then subjected to a selected ternary system optimized for the CPC (centrifugal partition chromatography): ethyl acetate–ethanol–water (9:2:10, v/v/v). The separation was carried out isocratically at a flow rate of 25 mL/min at 1200 rpm, affording seven fractions A to G. TLC of fractions B, C and F displayed a single spot corresponding to three new glycosylated sesquiterpenoids. Their structures were established by using spectroscopic data in comparison to those reported in the literature. Furthermore, the isolates were evaluated for their leishmanicidal and cytotoxic effects. No cytotoxic effect was observed against the three cancer cell lines (HL60, JURKAT and REH), but compound 1 showed a weak antiprotozoal activity. Liquid–liquid partition and CPC turned to be a versatile technique of glycoside purification which is environmentally friendly and requires a limited amount of organic solvents.

Abstract:

A new guaiane-type sesquiterpenoid, 10β- O-methyl-1αH,5αH-guaia-6-en-4β-ol (1) along with two known compounds, 10- O -methyl alismoxide (2) and alismoxide (3) were isolated from a population of Bornean soft coral Xenia stellifera. The structure of this metabolite was elucidated based on spectroscopic data such as NMR and HRESIMS. These compounds were evaluated for their biological activity against adult T-cell leukemia cell line.

Abstract:

Secoatractylohexone A (1), an unprecedented secoguaiane lactone glycoside featuring 6/7 cores and dihydroxy-9-guaine-3-one 11-O-β-d-glucopyranoside (2), a 9,10-unsaturated guaiene-type glycoside possessing an uncommon scaffold, were isolated from the water-soluble portion of the ethanolic extract of Atractylodes lancea rhizomes together with five known compounds (3–7). The structures of 1 and 2 were elucidated on the basis of extensive spectroscopic data and application of the CD technique. The potential biological activities of secoatractylohexone A were predicted by network pharmacology in silico, the result of which indicated that secoatractylohexone A may be used to treat type II diabetes.
