Abstract
Two new sesquiterpenoids, homalolides C - D (1‒2), were co-isolated from the rhizomes of Homalomena pendula (Blume) Bakh.f collected in Vietnam with five known ones, aromadendrane-4α,10α-diol (3), bullatantriol (4), 1β,4β,6α-trihydroxy-eudesmane (5), 1β,4β,6β-trihydroxyeudesmane (6), and 1β,4β,7α-trihydroxy-eudesmane (7). The structures and relative configuration of new compounds were elucidated by 1 D-/2D-NMR, IR, UV and HRESIMS analyses, and by comparisons to the reported data in the literature. Homalolide C presented an unprecedented skeleton with the 4/8 bicyclic system. All isolates did not exhibit appreciable inhibitory effects on LPS-induced NO production in the RAW 264.7 macrophage cell line and on the growth of human lung cancer cell line (SK-LU-1).

[PMID: 37421692 DOI: 10.1016/j.bioorg.2023.106707] [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: 12/04/2022] [Revised: 06/12/2023] [Accepted: 06/26/2023] [Indexed: 07/10/2023]
Abstract
Phytochemical study of Magnolia grandiflora led to the isolation of 39 sesquiterpenoids, including 15 new compounds (1-15). Compounds 1 and 2 are discovered to be the first 13-norgermacrane type sesquiterpenoids in natural products. Compound 15 is a rare 5,6-seco-guaiane type sesquiterpene and its possible biogenic precursor is presumed to be compound 20. Subsequent structural modification for compound 28 led to 21 derivatives, among which 15 derivatives were new compounds. All compounds were tested for the inhibitory effects on three tumor cell lines, and 17 compounds were active with the IC50 values ranging from 1.91 ± 0.39 μM to 12.29 ± 1.68 μM. The structure-activity relationships implied that an α, β-unsaturated lactone group was an important active group for the cytotoxicity. Two most active compounds (19 and 29) with low toxicity on normal human liver cell line were selected for further mechanism study. Compound 29 could induce apoptosis on Colo320DM cells through influencing the key apoptotic related proteins, such as PARP, Cleaved PARP, cleaved Caspase-3, and pro-Caspase 3. In addition, compound 19 with the best cytotoxic activity on HEL cells also could induce the apoptosis in dose- and time-dependent manners. In summary, our investigation implied that compounds 19 and 29 are two new potential anti-cancer candidates for ongoing study in the future.

Abstract
Sixteen sesquiterpenoids including two new ones, homalolides A - B (1‒2), were firstly isolated from the methanolic extract of the rhizomes of Homalomena pendula collected in Vietnam. The structures and relative stereochemistry of new compounds were elucidated by 1D-/2D-NMR, IR, UV and HRESIMS analyses. The GCMS experiment demonstrated that homalolide A (1) is an artifact due to the methylation during methanolic extraction process. All isolates (1‒16) were tested for their inhibitory activities against lipopolysaccharide-induced nitric oxide production in the RAW 264.7 macrophage cell line. Compounds 1, 3, 6‒8, 10‒12 displayed moderate inhibitory effect on NO production with IC50 values ranging from 35.41 to 64.06 μM.

Abstract
Nine previously undescribed sesquiterpenoids, named magnograndins A-I, as well as fourteen known ones, were obtained from the 70% acetone extract of the leaves of Magnolia grandiflora. Their structures were ascertained based on the spectroscopic evidences. The assignment of the relative configuration of magnograndin A was further confirmed by single-crystal X-ray diffraction analysis. 1β,10α-Epoxyparthenolide, parthenolide, and micheliolide exhibited potent cytotoxic activity against MDA-MB-468, AGS, HCT116, Hela, and MDA-MB-231 human cancer cell lines with IC50 values ranging from 1.76 to 16.11 μM. 1β,10α-Epoxyparthenolide and micheliolide potently inhibited NF-κB transcriptional activity with IC50 of 13.92 and 8.95 μM, respectively. The expression levels of NF-κB downstream protein p65 and XIAP were clearly down-regulated in 1β,10α-epoxyparthenolide and micheliolide treated cells, which demonstrated the inhibition of NF-κB signaling pathway.

Abstract
The composition of the volatile compounds isolated by simultaneous distillation-extraction (SDE) and headspace-solid phase microextraction (SPME) from flowers of Magnolia grandiflora growing in Cuba was investigated by GC/FID and GC/MS. Sixty-seven and thirty-four components were obtained by SDE and SPME, respectively. β-Pinene (10.5%), geraniol (7.4%) and germacrene D (6.2%) were the main constituents of the volatile oil isolated by SDE, while (E)-β-ocimene (24.6%), geraniol (18.9%), β-elemene (11.2%) and germacrene D (9.9%) were the most abundant in the headspace of the flowers, respectively.

Abstract
The ethanolic extracts from 30 plant species were tested for their nematicidal activity against nematodes Bursaphelenchus xylophilus (Steiner & Buhrer) Nickle and Panagrellus redivivus (L.) Goodey. The leaf extract of Magnolia grandiflora L. exhibited the strongest nematicidal activity against both nematodes, causing 73 and 100% mortality respectively within 48 h at 5 mg mL(-1). A new nematicidal sesquiterpene was obtained from the leaves of M. grandiflora. The compound was determined to be 4,5-epoxy-1(10)E,11(13)-germacradien-12,6-olide, based on spectroscopic methods including 2D NMR techniques. The median lethal concentrations (LC50) of the compound against B. xylophilus and P. redivivus were 71 and 46 mg L(-1) respectively at 48 h. This is the first report of Magnoliaceae species with nematicidal activity.
