Protective effect of phenylpropionamides in the seed of Cannabis Sativa L. on Parkinson's disease through autophagy.

Parkinson's disease (PD) is the second most common neurodegenerative disease in the world. As one of the major degradation pathways, autophagy plays a pivotal role in maintaining the effective turnover of proteins and damaged organelles in cells. Lewy bodies composed of α-synuclein (α-syn) abnormally aggregated in the substantia nigra are important pathological features of PD, and autophagy dysfunction is considered to be an important factor leading to abnormal aggregation of α-syn. Phenylpropionamides (PHS) in the seed of Cannabis sativa L. have a protective effect on neuroinflammation and antioxidant activity. However, the therapeutic role of PHS in PD is unclear. In this study, the seeds of Cannabis sativa L. were extracted under reflux with 60% EtOH-H2O, and the 60% EtOH-H2O elution fraction was identified as PHS with the UPLC-QTOF-MS. The 1-methyl-4-phenyl-1,2,3,6-tetrahydro-pyridine (MPTP)-induced PD model in C57BL/6 J mice was used for behavioral and pharmacodynamic experiments. Behavioral symptoms were improved, Nissl-stained and TH-positive neurons in the substantia nigra were significantly increased in PHS-treated MPTP-induced PD model mice. Compared with the model group, PHS treatment reduced the expression level of α-syn, and the expression of TH increased significantly by western blotting, compared with the model group, the PHS group suppressed Caspase 3 and Bax expression and promoted Bcl-2 expression and levels of p62 decreased significantly, the ratio of LC3-II/I and p-mTOR/mTOR in the PHS group had a downward trend, suggesting that the therapeutic effect of PHS on MPTP-induced PD model mice may be triggered by the regulation of autophagy.

ETHNOPHARMACOLOGICAL RELEVANCE: Dichroa febrifuga Lour., a toxic but extensively used traditional Chinese medicine with a remarkable effect, is commonly called "Changshan" in China. It has been used to treat malaria and many other parasitic diseases. AIM OF THE REVIEW: The study aims to provide a current overview of the progress in the research on traditional use, phytochemistry, pharmacological activities, toxicology, and methods of toxicity reduction of D. febrifuga. Additionally, further research directions and development prospects for the plant were put forward. MATERIALS AND METHODS: The article uses "Dichroa febrifuga Lour." "D. febrifuga" as the keyword and all relevant information on D. febrifuga was collected from electronic searches (Elsevier, PubMed, ACS, CNKI, Google Scholar, and Baidu Scholar), doctoral and master's dissertations and classic books about Chinese herbs. RESULTS: 30 chemical compounds, including alkaloids, terpenoids, flavonoids and other kinds, were isolated and identified from D. febrifuga. Modern pharmacological studies have shown that these components have a variety of pharmacological activities, including anti-malarial activities, anti-inflammatory activities, anti-tumor activities, anti-parasitic activities and anti-oomycete activities. Meanwhile, alkaloids, as the material basis of its efficacy, are also the source of its toxicity. It can cause multiple organ damage, including liver, kidney and heart, and cause adverse reactions such as nausea and vomiting, abdominal pain and diarrhea. In the current study, the toxicity can be reduced by modifying the structure of the compound, processing and changing the dosage forms. CONCLUSIONS: There are few studies on the chemical constituents of D. febrifuga, so the components and their structure characterization contained in it can become the focus of future research. In view of the toxicity of D. febrifuga, there are many methods to reduce it, but the safety and rationality of these methods need further study.

Revealing the "Yin-Jing" mystery veil of Platycodon grandiflorum by potentiating therapeutic effects and lung-oriented guidance property.

ETHNIC PHARMACOLOGICAL RELEVANCE: "Yin-Jing" medicine (YJM) has been widely used by both ancient and modern Chinese medicine practitioners during long-term clinical practice. However, it remains unclear how to best guide other medicines to the targeted organs in a traditional Chinese medicine (TCM) prescription. Here, in an attempt to explain the scientific connotation of the YJM property (YJMP) attributed to a basic TCM theory, Platycodon grandiflorum (PG) was chosen as a case study to reveal the mystery of YJMP theory. AIM OF THE STUDY: The main purpose of this study is to employ modern chemical and molecular biology methods to confirm the "Yin-Jing" effect of PG, and further clarify its material basis and related possible mechanism. MATERIALS AND METHODS: The ammonia-induced lung injury rat model was utilized to determine the optimal dosage of traditional prescription Hui Yan Zhu Yu decoction (HYZYD) using Wright Giemsa staining, HE staining, Masson staining, and TUNEL analysis. With the same way, PG was confirmed to have potentiating therapeutic effect (PTE) by comparison with HYZYD and [HYZYD-PG]. TMT proteomics was used to reveal the "Yin-Jing" mechanism of action. Western blot assay (WB) was employed for verification of differentially expressed proteins. Additionally, four non-crossing fragmentations (Fr. A-D) were characterized by RPLC/SEC-ELSD and HILIC-ESI--Q-OT-IT-MS techniques. The PTE and guidance property assays were utilized to evaluate "Yin-Jing" functions by a compatible combination of hydroxysafflor yellow A (HYA) using qPCR, FCM, WB, HPLC, high content cell imaging (HCI) and high-resolution live-cell imaging (HRLCI) techniques. RESULTS: The HYZYD-M (medium dose group) significantly improved the lung injury level in a pneumonia model of rats. PG enhanced the therapeutic effect of HYZYD ascribed to Yin-Jing PTE functions. TMT proteomics revealed a category of differentially expressed proteins ascribed to Golgi-ER between HYZYD and [HYZYD-PG]. Fr. C (i.e., saponins) and Fr. D (i.e., lipids) were determined as therapeutic fragmentations via the LPS-induced A549 cell injury model; however, Fr. B (fructooligosaccharides and small Mw fructans) had no therapeutic effect. Further compatibility PTE assays confirmed Fr. B significantly improved efficiency by a combination of HYA. The guidance assays showed Fr. B could significantly increase the uptake and distribution of HYA into lung cells and tissues. HCI assays showed that Fr. B increased uptake of HYA accompanied by significant activation of Golgi-ER. Unlike Fr. B, HRLCI showed that Fr. A, C and D were not only unobvious activations of Golgi-ER but also insignificant facilitation of colocalizations between HYA and Golgi-ER. CONCLUSIONS: Fr. B is believed to be a key YJMP material basis of PG attributed to Yin-Jing PTE with characteristic of lung-oriented guidance property, whereas another abound Fr. C was determined to have synergistic effects rather than Yin-Jing material basis.

Insight of "Yin-Jing" medical property ofLigusticum chuanxiong Hort. via pharmacokinetics and tissue distributions by ultra-performance liquid chromatography-triple quadrupole mass spectrometry.

ETHNOPHARMACOLOGICAL RELEVANCE: Ligusticum chuanxiong Hort. (Chuanxiong, LC), as an important traditional Chinese medicine (TCM), can not only be used as a monarch herb but also be used as a classic "Yin-Jing" () medicine in compound prescriptions, e.g., Buyang Huanwu Decoction (BHD). Although LC has the effect of guiding components into the brain in BHD, there is still a lack of scientific evidence on this "Yin-Jing" effects. Herein, we used pharmacokinetics and tissue distributions to investigate "Yin-Jing" effects of LC. To simplify the study, four major constituents in BHD, i.e., Calycosin (CA), astragaloside IV (AI), paeoniflorin (PA), and amygdalin (AM) were combined to form a simple compound (abbreviated as CAPA here) to replace the original BHD in this paper. The Yin-Jing medical property of LC was confirmed by the compatibility of CAPA with LC or its different fractions (Fr. A âˆ¼ Fr. F). AIM OF THE STUDY: To explore the "Yin-Jing" medical property of LC via pharmacokinetics and tissue distributions by ultra-performance liquid chromatography-triple quadrupole mass spectrometry (UPLC-QQQ-MS). MATERIALS AND METHODS: The contents of CA, AI, PA, and AM were simultaneously determined by the established and validated UPLC-QQQ-MS method in different rat tissues and plasma after administration of CAPA with the combination of LC or Fr. A âˆ¼ Fr. F. The pharmacokinetic parameters, e.g., Tmax, Cmax, AUC0-t and MRT0-t, were calculated to evaluate the efficiency of "Yin-Jing". RESULTS: The Cmax and AUC0-t of CA, AI, PA, and AM were remarkably increased in rat brain tissues compared with those of the control group after compatibility of LC. This demonstrated that LC has the Yin-Jing effects on brain tissues. Additionally, Fr. B or Fr. C might be the material basis by specifically studying the distributions of CA, AI, PA, and AM in brain tissue based on mutual compatibility. The effects of Fr. B and Fr. C on distributions of these constituents in other tissues or plasma was also studied to verify the effects of Yin-Jing of LC. The results showed that the same upward trend is found in heart, liver and plasma, but the intensity is insignificant as that in brain tissue. Furthermore, the Cmax and AUC0-t of some analytes in the rat spleen, lung, and kidney were significantly decreased compared with the control group (P < 0.05 or 0.01). CONCLUSIONS: LC has the function of Yin-Jing, especially guiding the components into the brain tissue. Moreover, Fr. B and Fr. C is suggested to be the pharmacodynamic material basis for the effect of Yin-Jing of LC. These finding explained that it was recommended to add LC into some prescriptions for treating cardiovascular and cerebrovascular diseases caused by Qi deficiency and blood stasis. This has laid a certain foundation for the research on the Yin-Jing efficacy of LC to better clarify the theory of TCM and guide the clinical application of Yin-Jing drugs.

UHPLC-Orbitrap-Fusion-TMS-Based Metabolomics Study of Phenylpropionamides in the Seed of Cannabis sativa L. against Alzheimer's Disease.

Phenylpropionamides in the seed of Cannabis sativa L. (PHS) have a protective effect on neuroinflammation and antioxidant activity. In this study, the UHPLC-Orbitrap-fusion-TMS-based metabolomics approach was used to analyze the serum samples and identify potential biomarkers in Streptozotocin (STZ) induced Alzheimer's disease (AD) rats. The results revealed that primary bile acid biosynthesis and taurine and hypotaurine metabolism were significantly correlated with STZ-induced AD rats. In addition, the key enzymes in these two pathways were verified at the protein level. The levels of cysteine dioxygenase type I (CDO1), cysteine sulfinic acid decarboxylase (CSAD), cysteamine (2-aminoethanethiol) dioxygenase (ADO), 7α-hydroxylase (CYP7A1), and sterol 12α-hydroxylase (CYP8B1) were the key enzymes affecting the two pathways in AD rats compared with the control group (CON). Furthermore, after a high-dose group of phenylpropionamides in the seed of Cannabis sativa L. (PHS-H) was administrated, the levels of CDO1, CSAD, CYP7A1, and CYP8B1 were all callback. These findings demonstrate for the first time that the anti-AD effect of PHS is associated with the regulation of primary bile acid biosynthesis and taurine and hypotaurine metabolism in STZ-induced AD rats.

New chromones from the roots of Saposhnikovia divaricata (Turcz.) Schischk with anti-inflammatory activity.

Fifteen new chromones, sadivamones A-E (1-5), cimifugin monoacetate (6), sadivamones F-N (7-15), together with fifteen known chromones (16-30), were isolated from the ethyl acetate portions of 70% ethanol extract of Saposhnikovia divaricata (Turcz.) Schischk roots. The structures of the isolates were determined using 1D/2D NMR data and electron circular dichroism (ECD) calculations. Meanwhile, LPS induced RAW264.7 inflammatory cell model was used to determine the potential anti-inflammatory activity of all the isolated compounds in vitro. The results showed that compounds 2, 8, 12-13, 18, 20-22, 24, and 27 significantly inhibited the production of lipopolysaccharide (LPS)-induced NO in macrophages. To determine the signaling pathways involved in the suppression of NO production by compounds 8, 12 and 13, we investigated ERK and c-Jun N-terminal protein kinase (JNK) expression by western blot analysis. Further mechanistic studies demonstrated that compounds 12 and 13 inhibited the phosphorylation of ERK and the activation of ERK and JNK signaling in RAW264.7 cells via MAPK signaling pathways. Taken together, compounds 12 and 13 may be valuable candidates for the treatment of inflammatory diseases.

ETHNOPHARMACOLOGICAL RELEVANCE: The lateral root of Aconitum carmichaelii Debeaux. (also known as Fuzi in Chinese) is a toxic Chinese medicine but widely used in clinical practice with remarkable effects. It is specifically used to treat cardiovascular diseases, rheumatoid arthritis, and other diseases, in Korea, Japan, and India. AIM OF THIS REVIEW: This study aimed to summarize and discuss the effects of drug processing on toxicity, chemical composition, and pharmacology of the lateral root of Aconitum carmichaelii Debeaux. This review could provide feasible insights for further studies. MATERIALS AND METHODS: Relevant information on phytochemistry, pharmacology, and toxicology of Fuzi was collected through published materials and electronic databases, including the Chinese Pharmacopoeia, Flora of China, Web of Science, PubMed, Baidu Scholar, Google Scholar, and CNKI. RESULTS: More than 100 chemical compounds, including alkaloids, flavonoids, and polysaccharides were revealed. Modern pharmacological studies show that these chemical components have good effects on anti-inflammatory, anti-tumor, anti-aging, treatment of cardiovascular diseases, and improving immunity. Di-ester alkaloids are the main source of Fuzi toxicity. Increasing studies have shown that Fuzi can induce multiple organ damage, especially cardiotoxicity and neurotoxicity. At present, most of the Fuzi used in clinical practice are processed. The processing affects the chemical structure, pharmacology, and toxicology of Fuzi. Moreover, different processing methods have different effects on Fuzi. CONCLUSIONS: This review analyzed the effects of Fuzi processing methods on its toxicity and efficiency. The lateral roots of aconite are the known medicinal part of Fuzi; however, the aerial parts of aconite are understudied and require further research to expand its medicinal potential. Processing and compatibility are the primary means to reduce Fuzi toxicity. Nevertheless, establishing a reasonable unified safe dose range requires further discussion.
