[PMID: 37797453 DOI: 10.1016/j.bioorg.2023.106845] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 09/02/2023] [Accepted: 09/05/2023] [Indexed: 10/07/2023]
Abstract
Blapspirooxindoles A-C (1-3), three novel spirooxindole alkaloids with a unique spiro[chromane-4,3'-indoline]-2,2'-dione motif, blapcumaranons A and B (4 and 5), two new 2-cumaranon derivatives, blapoxindoles A-J (6-15), ten new oxindole alkaloid derivatives, along with one known compound (16), were isolated from the whole bodies of Blaps japanensis. Their structures including absolute configurations were determined by using spectroscopic, X-ray crystallographic, and computational methods. Compounds 1-11 and 13 exist as racemic mixtures in nature, and their (-)- and (+)-antipodes were separated by chiral HPLC. Biological evaluations of these compounds were determined with multiple assays including anti-tumor, anti-inflammatory, and renal protection activities in vitro. Several compounds displayed effective activity in one or more assays.

Qian XL, Meng D, Liu H, Liu CH, Zhou P, Yang YH, Wang JP, Xiao H, Ding ZT. Proliferation Inhibitory Activity of Quinones from Blaps rynchopetera Defense Secretion on Colorectal Tumor Cells. Chin J Integr Med 2023:10.1007/s11655-023-3696-y. [PMID: 37071326 DOI: 10.1007/s11655-023-3696-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/22/2022] [Indexed: 04/19/2023]
Abstract
OBJECTIVE To explore the proliferation inhibitory effect of quinones from Blaps rynchopetera defense secretion on colorectal tumor cell lines. METHODS Human colorectal cancer cell HT-29, human colorectal adenocarcinoma cell Caco-2 and normal human colon epithelial cell CCD841 were chosen for the evaluation of inhibitory activity of the main quinones of B. rynchopetera defense secretion, including methyl p-benzoquinone (MBQ), ethyl p-benzoquinone (EBQ), and methyl hydroquinone (MHQ), through methyl thiazolyl tetrazolium assay. The tumor-related factors, cell cycles, related gene expressions and protein levels were detected by enzyme-linked immunosorbent assy, flow cytometry, RT-polymerase chain reaction and Western blot, respectively. RESULTS MBQ, EBQ, and MHQ could significantly inhibit the proliferation of Caco-2, with half maximal inhibitory concentration (IC50) values of 7.04 ± 0.88, 10.92 ± 0.32, 9.35 ± 0.83, HT-29, with IC50 values of 14.90 ± 2.71, 20.50 ± 6.37, 13.90 ± 1.30, and CCD841, with IC50 values of 11.40 ± 0.68, 7.02 ± 0.44 and 7.83 ± 0.05 µg/mL, respectively. Tested quinones can reduce the expression of tumor-related factors tumor necrosis factor α, interleukin (IL)-10, and IL-6 in HT-29 cells, selectively promote apoptosis, and regulate the cell cycle which can reduce the proportion of cells in the G1 phase and increase the proportion of the S phase. Meanwhile, tested quinones could up-regulate mRNA and protein expression of GSK-3β and APC, while down-regulate that of β-catenin, Frizzled1, c-Myc, and CyclinD1 in the Wnt/β-catenin pathway of HT-29 cells. CONCLUSION Quinones from B. rynchopetera defense secretion could inhibit the proliferation of colorectal tumor cells and reduce the expression of related factors, which would be functioned by regulating cell cycle, selectively promoting apoptosis, and affecting Wnt/β-catenin pathway-related mRNA and protein expressions.

Fitoterapia 2023; 164:105386. [PMID: 36473538 DOI: 10.1016/j.fitote.2022.105386] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 11/29/2022] [Accepted: 12/02/2022] [Indexed: 12/12/2022]
Abstract
Blaps rynchopetera Fairmaire is a medicinal insect of Yi-nationality medicine used for a long time in Yunnan, China. In the present study, a new blapsimidazolium A (1), together with twelve known N-containing compounds (2-13), were isolated from this insect. The structures were elucidated by extensive spectroscopic analyses (1D and 2D NMR, HR-MS) and comparisons with the reported literature. Blapsimidazolium A was identified as racemic mixture by optical rotation and chiral analysis. Blapsimidazolium A (1) has a unique architecture containing an imidazolium carboxylate moiety. The results of molecular docking showed that blapsimidazolium A bound well to IL-1β, IL-6 and iNOS. The racemates of (±)-blapsimidazolium A (1) exerted anti-inflammatory activity in LPS-stimulated THP-1 cells by significantly decreasing the production of the proinflammatory cytokines IL-1β, IL-6 and iNOS. This is the first report describing the anti-inflammatory activity of this type imidazolium carboxylate derivative.

Abstract
The edible Blaps rynchopetera Fairmaire is widely used for its various medicinal effects. From its ethyl acetate fraction, three new hydroxytyrosol dimers, rynchopeterine H (1), rynchopeterine I (2) and trans-2-(3,4-dihydroxy-phenyl)-3-hydroxy-7-(2-hydroxyethyl)-1,4-benzdioxane (3), together with four known similar dimers were obtained by chromatography of silica gel and Sephadex LH-20. Their structures were identified by HRESIMS, 1D and 2D NMR spectra analysis. Compounds 1-4 were obtained as a mixture, and cytotoxicity screening for HepG2, Caco-2, U251, AGS, B16 and Bel-7402 cell lines showed that the mixture of compounds 1-4 exhibited significantly selective cytotoxicity and good inhibitory activity on the proliferation of mouse melanoma cells (B16) with an IC50 value of 27.37 μg·mL−1.
