PHYTOCHEMISTRY 2023; 214:113821. [PMID: 37567352 DOI: 10.1016/j.phytochem.2023.113821] [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: 05/05/2023] [Revised: 08/03/2023] [Accepted: 08/07/2023] [Indexed: 08/13/2023]
Abstract
Ten previously unreported eremophilane lactones (parasalbolides A-J), including three pairs of C-10 epimers (parasalbolides A and G, B and H, and F and I, respectively), were isolated and identified from the whole plant of Parasenecio albus. Their structures were established on the basis of the HRESIMS and NMR spectroscopic analyses, combined with the comparison of the ECD spectra. The absolute configuration of parasalbolide A was confirmed by single-crystal X-ray diffraction using Cu Kα radiation. Parasalbolides A-J represent the first examples of 1,2,10-trioxygenated eremophila-7(11),8-dien-12,8-olides. The cytotoxic and immunosuppressive activities of selected isolates were evaluated and the (10S)-eremophilane lactones (parasalbolides A, B, and F) showed more potent activities than the (10R)-ones (parasalbolides G, H, and I).

Abstract
1H and 13C Nuclear Magnetic Resonance (NMR) signals and specific rotations of eremophilane sesquiterpenoids are cumulated as a series of review articles. In the first chapter of this review, 332 bicyclic eremophilanes, namely with no furan or lactone rings (except for epoxides), without 3-OR functionality (except for hydroxy, acetoxy, and carbonyl) are listed in tables. These data may help chemists working in the area of natural products chemistry as well as synthetic scientists.

Abstract
More than 100 Ligularia species and those of several related genera (Cremanthodium, Cacalia, Senecio, and others) in the plant family Senecioneae grow in East Asia. For many years, researchers have studied the chemical constituents of these plants, and terpenoids, flavonoids, sterols, alkaloids, and aromatic compounds have been isolated. Among these, in particular, numerous sesquiterpenoids were reported. In this contribution, relevant chemical studies are described mainly from literature reports appearing since 2000, inclusive of investigations performed by the present authors, on the diversity in secondary metabolites of Ligularia growing in the Hengduan Mountains area of China, focusing on eremophilane sesquiterpenoids and other metabolites. Terpenoids and aromatic compounds (totaling 1049), both new and known, are listed. Genetic studies and synthesis investigations are also reviewed briefly.

Abstract
This report illustrated isolation and identification of 42 compounds comprising five (spicatainoids A-E) undescribed eremophilanolide type sesquiterpenoids and one undescribed nor-eremophilane (spicatainoid F) from Ligularia subspicata.. Among all the isolated new compounds, 4 is reported as the first enantiomeric form of novel eremophilanolide type sesquiterpenoid. Comprehensive analysis of HRESIMS, 1D/2D NMR, experimental circular dichroism (CD), calculated ECD analysis, and X-ray crystallographic (XRD) analysis validated the complete configuration and confirmation of these isolated compounds. All the isolated compounds were tested for the anti-inflammatory potential by measuring the amount of nitric oxide production. Among the tested compounds, 4 was the most effective with 90% NO-inhibition activity. Compounds 1, 2, 3, 9, 10 18, 29, 34, 35 exhibited moderate inhibitory effects against the production of NO, while other compounds displayed no activity even at the concentration of 50 μM. Additionally, compounds 1, 3 and 4 presented moderate anti-inflammatory activity by inhibiting the release of pro-inflammatory cytokines (TNF-α, IL-1β, and IL-6) in LPS-stimulated N9 cells. The IC50 values of compounds 1, 3 and 4 were calculated 39.6 ± 2.7, 42.5 ± 3.8 and 27.60 ± 1.9 μΜ.

Abstract
Two new lindenane sesquiterpenes were obtained from the roots of Lindera myrrha. These compounds were structurally elucidated by HRMS data, extensive NMR analyses, and comparison between experimental and theoretical 13C-NMR data. Myrrhalindenane A is the first monomeric seco-d lindenane displaying a non-rearranged, cyclohexanic C-ring. Myrrhalindenane B is the second occurrence of an angular lindenane-sesquiterpene related to a C6-C7 lactonization.

Abstract
Twenty-two new sesquiterpenoids with four skeletal types and 15 known analogues were isolated from the whole plants of Ligularia rumicifolia. The structures of the isolates were elucidated based on comprehensive spectroscopic data analysis. Compound 1 is a C14 nor-sesquiterpenoid featuring a 6/6/6 tricyclic skeleton with a 9,13-ether bridge. The absolute configuration of 2 was established through single-crystal X-ray diffraction data. Compounds 13-16 exhibited in vitro antiproliferative activity against the four human tumor cell lines A-549, HGC-27, HeLa, and MV4-11. Specifically, compounds 13 and 16 showed antiproliferative activity against the MV4-11 cell line with IC50 values of 0.5 ± 0.2 and 1.1 ± 0.5 μM, respectively.

Abstract
Four samples of Ligularia virgaurea collected in China afforded three new eremophilane sesquiterpenoids, one new norsesquiterpenoid, and two new dinorsesquiterpenoids as well as 28 known compounds. All the four samples belonged to the ligularol type (L type), one of the five chemotypes we have described for this species. The configuration of the previously reported eremophila-7(11),9-dien-12,8-olide is revised to be H-8α. The absolute configuration of ethyl 8-oxoeremophila-7(11),9-dien-12-oate was established to be 4 S,5 R by a DFT calculation.

Abstract
The terpenoid constituents of Ligularia virgaurea (30 samples), Ligularia pleurocaulis (8 samples), Ligularia dictyoneura (8 samples), Ligularia brassicoides (5 samples), Ligularia lingiana (1 sample), and Ligularia liatroides (1 sample)(all belonging to section Senecillis of Ligularia, Asteraceae and collected in Yunnan, Sichuan, Qinghai, and Gansu provinces, China), from which 220 compounds were isolated, including 113 novel ones, are reviewed. Five chemotypes were identified in L. virgaurea based on their chemical constituents, while three clades were detected from the base sequences. Although intra-specific diversity was found in L. virgaurea, more samples were needed of other species in order to reach a definite conclusion. Inter-specific diversity was also examined in section Senecillis but was restricted due to the scarcity of samples. Synthetic studies on chiral natural products to determine their absolute configurations, especially those of riccardiphenols A and B as well as crispatanolide, which were all isolated from the liverwort, are briefly reviewed.

Abstract
Seven eremophilane-type sesquiterpene glucosides, alticolosides A-G, have been isolated from aerial parts of the endemic Far Eastern species Ligularia alticola Worosch. (Family Asteraceae) along with two known compounds, monoterpenoid glycoside (4S)-α-terpineol 8-O-β-D-glucopyranoside and norditerpenoid glycoside 7(8)-dihydro-β-ionone 3-O-β-D-glucopyranoside. Alticoloside D was identified with the earlier known 8-O-(β-D-glucopyranosyl)-2-oxo-eremophila-1(10),8,11-triene, but the stereostructure of the latter was revised on the basis of ROESY and CD data. All the glycosides are derivatives of new eremophilane-type aglycones, differing from known eremophilanes in details of planar and/or stereo structures except for the aglycone of alticoloside E.

Abstract
Ligularia vellerea and L. melanothyrsa have been found to share chemical characteristics based on geography. In one chemotype (Shangrila type), the major components were either 15-oxygenated furanoeremophilanes or eremophilanolides; and in another (Luguhu type), either 1-angeloyloxyfuranoeremophilanes or corresponding lactones. The two L. vellerea samples were found to have experienced hybridization with either L. cyathiceps or L. kanaitzensis; however, compounds typical of L. vellerea alone were isolated from them.
