Pharmacokinetics study of asperosaponin VI and its metabolites Cauloside A, HN saponin F and hederagenin
J Nat Med 2014 Jul;68(3):488-97.PMID:24615060DOI:10.1007/s11418-014-0821-4.
This experiment's with aim was to study the pharmacokinetics of asperosaponin VI and its three metabolites (Cauloside A, HN saponin F and hederagenin) via a sensitive high performance liquid chromatography connected with electrospray ionization triple quadrupole mass spectrum (HPLC-ESI-MS/MS). Chromatographic separation was achieved on a reverse phase C18 column with a gradient mobile phase of CH3CN-water with 0.1 % HCOOH at a flow rate of 0.3 mL/min. Sample analysis was simultaneously performed with a multiple reaction monitoring mode using target determination ions at m/z 927.5 → 603.4 for asperosaponin VI, m/z 811.1 → 603.4 for Cauloside A, m/z 649.4 → 603.4 for HN saponin F, m/z 71.4 → 393.3 for hederagenin and m/z 307.0 → 161.1 for warfarin as the internal standard. The calibration curve was linear at the range of 0.25-500 ng/mL, and the lower limit of quantification was 0.25 ng/mL for each compound. While the precisely intra-assay and inter-assay variabilities were <9.5 and 7.8 %, respectively; accuracy was determined at the concentrations of 5, 25, 100 ng/mL for all the analytes with the relative standard deviation (%) no more than 15.0 %. Consequently, the validated method could be successfully and precisely applied to the pharmacokinetic study of asperosaponin VI and its metabolites. As a result, the pharmacokinetic parameters of Cauloside A, HN saponin F and hederagenin such as T max were obtained at 9.33 ± 2.49, 7.33 ± 0.47 and 12.33 ± 2.36 h, respectively.
A Network Pharmacology-Based Study on the Anti-Lung Cancer Effect of Dipsaci Radix
Evid Based Complement Alternat Med 2020 Apr 27;2020:7424061.PMID:32419823DOI:10.1155/2020/7424061.
Objective: Dipsaci Radix (DR) has been used to treat fracture and osteoporosis. Recent reports have shown that myeloid cells from bone marrow can promote the proliferation of lung cancer. However, the action and mechanism of DR has not been well defined in lung cancer. The aim of the present study was to define molecular mechanisms of DR as a potential therapeutic approach to treat lung cancer. Methods: Active compounds of DR with oral bioavailability ≥30% and drug-likeness index ≥0.18 were obtained from the traditional Chinese medicine systems pharmacology database and analysis platform. The potential target genes of the active compounds and bone were identified by PharmMapper and GeneCards, respectively. The compound-target network and protein-protein interaction network were built by Cytoscape software and Search Tool for the Retrieval of Interacting Genes webserver, respectively. GO analysis and pathway enrichment analysis were performed using R software. Results: Our study demonstrated that DR had 6 active compounds, including gentisin, sitosterol, Sylvestroside III, 3,5-Di-O-caffeoylquinic acid, Cauloside A, and japonine. There were 254 target genes related to these active compounds as well as to bone. SRC, AKT1, and GRB2 were the top 3 hub genes. Metabolisms and signaling pathways associated with these hub genes were significantly enriched. Conclusions: This study indicated that DR could exhibit the anti-lung cancer effect by affecting multiple targets and multiple pathways. It reflects the traditional Chinese medicine characterized by multicomponents and multitargets. DR could be considered as a candidate for clinical anticancer therapy by regulating bone physiological functions.
Spectrum-Effect Relationships between Fingerprints of Caulophyllum robustum Maxim and Inhabited Pro-Inflammation Cytokine Effects
Molecules 2017 Oct 26;22(11):1826.PMID:29072610DOI:10.3390/molecules22111826.
Caulophyllum robustum Maxim (CRM) is a Chinese folk medicine with significant effect on treatment of rheumatoid arthritis (RA). This study was designed to explore the spectrum-effect relationships between high-performance liquid chromatography (HPLC) fingerprints and the anti-inflammatory effects of CRM. Seventeen common peaks were detected by fingerprint similarity evaluation software. Among them, 15 peaks were identified by Liquid Chromatography-Mass Spectrometry (LC-MS). Pharmacodynamics experiments were conducted in collagen-induced arthritis (CIA) mice to obtain the anti-inflammatory effects of different batches of CRM with four pro-inflammation cytokines (TNF-α, IL-β, IL-6, and IL-17) as indicators. These cytokines were suppressed at different levels according to the different batches of CRM treatment. The spectrum-effect relationships between chemical fingerprints and the pro-inflammation effects of CRM were established by multiple linear regression (MLR) and gray relational analysis (GRA). The spectrum-effect relationships revealed that the alkaloids (N-methylcytisine, magnoflorine), saponins (leiyemudanoside C, leiyemudanoside D, leiyemudanoside G, leiyemudanoside B, cauloside H, leonticin D, cauloside G, cauloside D, cauloside B, cauloside C, and Cauloside A), sapogenins (oleanolic acid), β-sitosterols, and unknown compounds (X3, X17) together showed anti-inflammatory efficacy. The results also showed that the correlation between saponins and inflammatory factors was significantly closer than that of alkaloids, and saponins linked with less sugar may have higher inhibition effect on pro-inflammatory cytokines in CIA mice. This work provided a general model of the combination of HPLC and anti-inflammatory effects to study the spectrum-effect relationships of CRM, which can be used to discover the active substance and to control the quality of this treatment.
Antifungal activity of sterols and dipsacus saponins isolated from Dipsacus asper roots against phytopathogenic fungi
Pestic Biochem Physiol 2017 Sep;141:103-108.PMID:28911735DOI:10.1016/j.pestbp.2016.12.006.
The in vivo antifungal activity of crude extracts of Dipsacus asper roots was evaluated against the phytopathogenic fungi Botrytis cinerea, Colletotrichum coccodes, Blumeria graminis f. sp. hordei, Magnaporthe grisea, Phytophthora infestans, Puccinia recondita and Rhizoctonia solani using a whole-plant assay method. Ethyl acetate and acetone extracts, at 1000μg/mL, suppressed the development of tomato gray mold (TGM) and tomato late blight (TLB) by 90%. Through bioassay-guided isolation, five antifungal substances were isolated from the D. asper roots and identified as β-sitosterol (1), campesterol (2), stigmasterol (3), Cauloside A (4) and a novel dipsacus saponin, named colchiside (3-O-β-d-xylopyranosyl-23-O-β-d-glucopyranosyl-28-O-β-d-(6-O-acetyl)-glucopyranosyl hederagenin) (5). Of those, Cauloside A (4) displayed the greatest antifungal efficacy against rice blast, TGM and TLB. Colchiside (5) moderately suppressed the development of TLB, but exhibited little effect against the other diseases. The synergistic effects of the isolated compounds against TLB were also assessed. Synergistic and additive interactions were observed between several of the sterol compounds. This study indicated that the crude extracts of, and bioactive substances from, the roots of D. asper suppress TGM and TLB. In addition, Cauloside A (4) and colchiside (5) could be used as antifungal lead compounds.
Analytical methods for determination of magnoflorine and saponins from roots of Caulophyllum thalictroides (L.) Michx. using UPLC, HPLC and HPTLC
J Pharm Biomed Anal 2011 Dec 15;56(5):895-903.PMID:21872415DOI:10.1016/j.jpba.2011.07.028.
Analytical methods including HPLC, UPLC and HPTLC are presented for the determination of major alkaloid and triterpene saponins from the roots of Caulophyllum thalictroides (L.) Michx. (blue cohosh) and dietary supplements claiming to contain blue cohosh. A separation by LC was achieved using a reversed phase column, PDA with ELS detection, and ammonium acetate/acetonitrile gradient as the mobile phase. Owing to their low UV absorption, the triterpene saponins were detected by evaporative light scattering. The eight triterpene saponins (cauloside H, leonticin D, cauloside G, cauloside D, cauloside B, cauloside C, Cauloside A and saponin PE) and the alkaloid magnoflorine could be separated within 35 min using HPLC method and within 8.0 min using UPLC method with detection limits of 10 μg/mL for saponins and 1 μg/mL for magnoflorine. The detection wavelength was 320 nm for magnoflorine and ELS detection was used for the eight saponins. The methods were also successfully applied to analyze different dietary supplements. For the products claiming to contain blue cohosh, there was a significant variability in the amounts of triterpene saponins detected. Calculations based on the analysis results for dietary supplements showed that maximum daily intake of alkaloid and saponins vary with the form (solids/liquids) and recommended doses according to the products label. Intakes varied from 0.57 to 15.8 mg/day for magnoflorine and from 5.97 to 302.4 mg/day for total saponins. LC-mass spectrometry coupled with electrospray ionization (ESI) method is described for the identification and confirmation of nine compounds in plant samples and dietary products. A HPTLC method was also developed for the fast chemical fingerprint analysis of C. thalictroides samples.
