Cassiaside C Inhibits M1 Polarization of Macrophages by Downregulating Glycolysis
Int J Mol Sci 2022 Feb 1;23(3):1696.PMID:35163619DOI:10.3390/ijms23031696.
Classically activated M1 macrophages reprogram their metabolism towards enhanced glycolysis to obtain energy and produce pro-inflammatory cytokines after activation by mammalian target of rapamycin complex 1 (mTORC1) and hypoxia-inducible factor (HIF)-1α. Thus, a strategy that constrains M1 polarization of macrophages via downregulation of glycolysis is essential for treating chronic inflammatory diseases. Cassiae semen has pharmacological activity against various inflammatory diseases. However, it is unclear whether specific compounds within Cassia seeds affect M1 polarization of macrophages. Here, we investigated whether Cassiaside C napthopyrone from Cassiae semen inhibits M1 polarization by downregulating glycolysis. We found that Cassiaside C reduced expression of inducible nitric oxide synthase and cyclooxygenase-2 and the phosphorylation of nuclear factor kappa B, all of which are upregulated in lipopolysaccharide (LPS)/interferon (IFN)-γ-treated Raw264.7 cells and peritoneal macrophages. Moreover, Cassiaside C-treated macrophages showed marked suppression of LPS/IFN-γ-induced HIF-1α, pyruvate dehydrogenase kinase 1, and lactate dehydrogenase A expression, along with downregulation of the phosphoinositide 3-kinases (PI3K)/AKT/mTORC1 signaling pathway. Consequently, Cassiaside C attenuated enhanced glycolysis and lactate production, but rescued diminished oxidative phosphorylation, in M1 polarized macrophages. Thus, Cassiaside C dampens M1 polarization of macrophages by downregulating glycolysis, which could be exploited as a therapeutic strategy for chronic inflammatory conditions.
Total synthesis of the antiallergic naphtho-alpha-pyrone tetraglucoside, Cassiaside C(2), isolated from cassia seeds
J Org Chem 2003 Aug 8;68(16):6309-13.PMID:12895065DOI:10.1021/jo034223u.
Toralactone 9-O-beta-d-glucopyranosyl-(1-->6)-beta-d-glucopyranosyl-(1-->3)-beta-d-glucopyranosyl-(1-->6)-beta-d-glucopyranoside (1, Cassiaside C(2)), isolated from Cassia obtusifolia L. and showing strong antiallergic activity, was concisely synthesized employing glycosyl trifluoroacetimidates as glycosylation agents. The unique naphtho-alpha-pyrone structure of toralactone (5) was constructed by condensation of orsellinate 8 with pyrone 9 in the presence of LDA as developed by Staunton and co-workers. The naphthol of toralactone showed minimal reactivity as an acceptor and was screened with various glycosyl donors. It is finally concluded that sacrifice of an excess amount of the trifluoroacetimidate or trichloroacetimidate donors (6f/6g, 6.0 equiv) in the presence of a catalytic amount of TMSOTf (0.05 and 0.3 equiv, respectively) afforded excellent yields of the coupling product, which was otherwise only a minor product under a variety of conditions examined.
[UPLC-MS~n analysis and certification evaluation of main chemical composition in naphthopyrone reference extract of Cassiae Semen]
Zhongguo Zhong Yao Za Zhi 2019 May;44(10):2102-2109.PMID:31355568DOI:10.19540/j.cnki.cjcmm.20190222.008.
The main chemical constituents of naphthopyrone reference extract( NRE) with definite content and relatively fixed chemical composition were analyzed and determined. Ultra-high performance liquid chromatography-LTQ-Orbitrap XL mass spectrometry and high performance liquid chromatography were used to systematically study NRE from the aspects of main chemical components and determination. The results showed that the chemical composition of naphthopyrone reference extract of Cassiae Semen was relatively fixed,and seven naphthalopyranones were identified. Cassiaside B_2,Cassiaside C_2,rubrofusarin-6-O-β-D-gentiobioside and Cassiaside C were the main chemical constituents of NRE,of which the determination and uncertainty results were( 11. 40+ 0. 26) %,( 11. 68+0. 24) %,( 16. 60+0. 22) %,( 28. 8+0. 48) %,respectively. This study contributed to the accurate evaluation of NRE and the foundation for the application of NRE in the quality control of Cassiae Semen,and provided a new idea for the replacement of single chemical reference substance by the reference extract of traditional Chinese medicine.
[Study on naphthopyrone reference extract and application on assay of Semen Cassiae]
Zhongguo Zhong Yao Za Zhi 2017 Sep;42(17):3385-3390.PMID:29192451DOI:10.19540/j.cnki.cjcmm.20170728.003.
A quality control method of Semen Cassiae was established by using naphthopyrone reference extract(NRE). Meanwhile, the feasibility about NRE replacing single component reference in quality control of traditional Chinese medicine was explored. After NRE of Semen Cassiae being prepared by chromatographic separation technology, we determined the three main components, cassiaside B2, rubrofusarin-6-O-β-D-gentiobioside and Cassiaside C. In the meantime, an HPLC analytical method, based on the NRE as standard substance, was developed to determinate the contents of three main components in Semen Cassiae. T-test was used for comparison of the determination results of the two methods(single chemical component and NRE as reference substances, respectively), and the T-test result demonstrated that there was no significant difference between the two methods. The results developed scientific basis for the application of NRE of Semen Cassia in the quality control, which could be applied for the quality control of traditional Chinese medicine using reference extract substituting single chemical reference, and provide a new research model for the quality control of Chinese medicine.
Screening of hypolipidemic active components in Jiang-Zhi-Ning and its preliminary mechanism research based on "active contribution value" study
J Ethnopharmacol 2021 May 23;272:113926.PMID:33596472DOI:10.1016/j.jep.2021.113926.
Ethnopharmacological relevance: Jiang-Zhi-Ning (JZN) is a traditional Chinese medicine formula, which has the effect of lowering blood lipid level and softening blood vessels. It is clinically used in the treatment of hyperlipidemia with significant curative effect. Aim of the study: This study aims to screen the active components of JZN that are responsible for its blood lipids lowering effect and lay the foundation for elucidating pharmacodynamic material basis of the hypolipidemic effect of the formula. Materials and methods: The hyperlipidemia model was used to evaluate the efficacy of the JZN effective extraction with the TC and TG of rat plasma as evaluation index. Then the established ultra-high performance liquid chromatography coupled with electrospray ionization-quadrupole-time of flight-mass spectrometry (UPLC-ESI-Q-TOF-MSn) method was utilized to analyze the components of JZN effective extraction and the absorbed components in rat plasma, the potential active components were screened by using the combined analysis results of in vivo and in vitro component identification. Then an established ultra-high performance liquid chromatography-triple quadrupole mass spectrometry (UPLC-QqQ-MSn) method was used to determine the content of potential active components and its natural ratio in JZN effective extraction, and a potential active components combination (PACC) was formed accordingly. Then a HepG2 cell hyperlipidemia model induced by sodium oleate was used to study the hypolipidemic activity of PACC by detecting the content of TG level in the model. Meanwhile, the real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to conduct preliminary research on its hypolipidemic mechanism. Then combined with the concept of "combination index" in the "median-effect principle", to calculate the half inhibitory concentration (IC50) values of PACC and each monomer component on inhibiting the TG level in the cell model. Subsequently, the "activity contribution study" was carried out, and the components with the sum of the "activity contribution value" of 85% were finally selected as the hypolipidemic active components of JZN. Results: The pharmacodynamics results showed that JZN effective extraction has displayed a good hypolipidemic effect. 45 components were identified in vitro, 108 components were identified from rat plasma, and 17 potential active components were screened out. The content determination result showed that the ratio of each potential active components in PACC as following: Cassiaside C: rubrofusarin-6-O-gentiobioside: aurantio-obtusin-6-O-glucoside: hyperoside: isoquercitrin: quercetin-3-O-glucuronide: (E)-2,3,5,4'-tetrahydroxystilbene-2-O-glucoside: rutin: emodin-8-O-glucoside: astragalin: armepavine: N-nornuciferine: coclaurine: O-nornuciferine: nuciferine: N-norarmepavine: higenamine = 3.30: 16.06: 9.15: 23.94: 98.40: 417.45: 189.68: 8.62: 1.28: 5: 3.51: 14.57: 1.06: 1.35: 1: 5.64: 6.06, and the activity study results showed that it has displayed a good hypolipidemic activity. Finally, the hypolipidemic active components screened out by the "activity contribution study" were: quercetin-3-O-glucuronide, (E)-2,3,5,4'-tetrahydroxystilbene-2-O-glucoside, isoquercitrin, O-nornuciferine, hyperoside and rubrofusarin-6-O-gentiobioside. Conclusions: A scientific and rational approach of screening the hypolipidemic active ingredients of JZN has been developed in the current study. In addition, the research revealed the blood lipid lowering mechanism of those ingredients, which provide a solid basis for further elucidating the hypolipidemic pharmacodynamic material basis and action mechanism of JZN.
