Dihydro-β-agarofuran-type sesquiterpenoids from the seeds of Tripterygium wilfordii (Thunder God Vine) and evaluation of their anti-osteoclastogenesis and immunosuppressive activities. Bioorg Chem 2023; 141:106886. [PMID: 37778191 DOI: 10.1016/j.bioorg.2023.106886] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2023] [Revised: 09/11/2023] [Accepted: 09/24/2023] [Indexed: 10/03/2023]
Abstract
Extensive phytochemical investigation of the seeds of Tripterygium wilfordii led to the identification of 54 polyesterified dihydro-β-agarofuran-type sesquiterpenoids, including 27 previously undescribed ones, named Tripwilin I-XXVII (1-27). Comprehensive spectroscopic and single-crystal X-ray diffraction analyses, along with electronic circular dichroism (ECD) calculations were used for the structural elucidation of the new compounds. Biological assay revealed that 37 compounds among the isolates exhibited significant inhibition against osteoclastogenesis induced by receptor activator of nuclear factor-κB ligand (RANKL) at 10 µM. Further investigation indicated that Triptogelin C-3 (54), with the most potent osteoclastogenesis inhibitory activity, regulated the osteoclast marker genes (MMP-9, c-Fos, CTSK, and TRAP) and proteins in a dose-dependent manner in vitro. Besides, celaforin D-1 (28), 1α,6β,15-triacetoxy-8α,9α-dibenzoyloxy-2α-hydroxydihydro-β-agarofuran (34), triptogelin A-2 (37), and chiapen D (49) showed moderate suppressive effects on the proliferation of T and B lymphocytes with IC50 values ranging between 8.1 ± 0.8 and 19.0 ± 0.9 μM.

Simultaneous determination of periplocin, periplocymarin, periplogenin, periplocoside M and periplocoside N of Cortex Periplocae in rat plasma and its application to a pharmacokinetic study. Biomed Chromatogr 2021; 36:e5283. [PMID: 34816469 DOI: 10.1002/bmc.5283] [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: 07/27/2021] [Revised: 10/28/2021] [Accepted: 11/08/2021] [Indexed: 11/09/2022]
Abstract
A sensitive and specific ultra-performance liquid chromatographic-tandem mass spectrometric method was developed and validated to simultaneously determine periplocin, periplocymarin (PM), periplogenin (PG), periplocoside M (PSM) and periplocoside N (PSN) in rat plasma. Acetonitrile was employed to precipitate plasma with appropriate sensitivity and acceptable matrix effects. Chromatographic separation was performed using a Waters HSS T3 column with a gradient elution using water and acetonitrile both containing 0.1% formic acid and 0.1 mm ammonium formate within 8 min. Detection was performed in positive ionization mode using multiple reaction monitoring. The method was fully validated in terms of selectivity, linearity, accuracy, precision, recovery, matrix effects and stability. Using this method, the concentrations of periplocin, PM, PG, PSM and PSN were established after oral administration of Cortex Periplocae extract to rats, and the pharmacokinetic characteristics of periplocin, PM, PG, PSM and PSN were assessed. Generally, PM, PG, PSM and PSN were eliminated slowly and their half-lives were all >8 h. In addition, the systemic exposure of PSM showed significant differences between genders with more than 10 times higher area under the concentration-time curve in female rats than in male rats. The findings of this study provide useful information for further research on Cortex Periplocae.
