Metabolic profiles of Fufang Xiling Jiedu capsule in rats by ultra-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry.

Fufang Xiling Jiedu capsule (FXJC), a traditional Chinese medicine that evolved from "Yinqiao Powder", is widely used for the treatment of cold and influenza. However, due to a lack of in vivo metabolism research, the chemical components responsible for the therapeutic effects still remain unclear. Hence, this study aimed to describe the metabolic profiles of the FXJC in rat plasma, urine, and feces.

Muscone suppresses myocardial ischemia damage by regulating PI3K/Akt signaling pathway.

Muscone is the main active compound of Moschus. In this paper, the cardioprotective effect of Muscone on acute myocardial ischemia (AMI) rats and its potential mechanisms were investigated. AMI rat models were established to evaluate the protective effect and antioxidative function of Muscone on the hearts.

Cardioprotective Effects of Tetrahydropalmatine on Acute Myocardial Infarction in Rats.

Tetrahydropalmatine (THP) is an active component of . The current study investigates the possible cardioprotective effects of tetrahydropalmatine in acute myocardial ischemia (AMI) rats. The anterior descending coronary artery of SD rats was ligated to establish an AMI model.

Anti-pandemic influenza A (H1N1) virus potential of Xilingjiedu capsule in vitro.

This study is aimed to investigate the effect of Xilingjiedu capsule (XLC), one of a preparation of traditional Chinese medicine, on influenza A (H1N1) virus as well as its preliminary mechanism. The median cell mortality (TC) to A549 cells and half effective inhibition concentration (IC) of influenza A (H1N1) virus of XLC were determined by MTT assay. Reed-Muench method was used to calculated the 50% tissue culture infective dose (TCID) of H1N1 virus to A549 cells.

Investigating the Pharmacological Mechanisms of SheXiang XinTongNing Against Coronary Heart Disease Based on Network Pharmacology and Experimental Evaluation.

SheXiang XinTongNing (XTN), which is composed of six traditional Chinese herbs, is a commercially available Chinese patent medicine that has been widely used as the treatment of coronary heart disease (CHD). Its mechanisms against coronary heart disease, however, remain largely unknown. This study aimed to investigate the pharmacological mechanisms of XTN against CHD via network pharmacology and experimental evaluation.

The rapid identification of chemical constituents in Fufang Xiling Jiedu capsule, a modern Chinese medicine, by ultra-performance liquid chromatography coupled with quadrupole-time-of-flight tandem mass spectrometry and data mining strategy.

Fufang Xiling Jiedu capsule is an effective Chinese medicine widely used for the treatment of cold and influenza. However, its chemical constituents had not been determined, which entailed a huge obstacle to further pharmacological studies, clinical-safe medication administration, and quality evaluation. To identify the chemical constituents in Fufang Xiling Jiedu capsule, an efficient and systematic approach using ultra-high-performance liquid chromatography coupled with a quadrupole time-of-flight mass spectrometry in conjunction with a data mining strategy was adopted in this study.

Chinese Medicine , Containing , and , Protects from Myocardial Ischemia Injury via Angiogenesis.

The Chinese patent medicine (SXXTN) is a clinical medication for coronary heart disease (CHD) and angina pectoris. This study aimed to investigate pharmacological effects of SXXTN and elucidate the role in angiogenesis on human umbilical vein endothelial cells (HUVECs) and acute myocardial ischemia (AMI) rats. We prepared SXXTN to treat the cells to reveal their effects on oxidative stress-damaged cell viability, as well as cell proliferation, migration, and tube formation processes.

Cytotoxic epimeric ginsenosides from the flower buds of Panax ginseng.

Three pairs of ginsenoside epimers, including three new compounds (2, 3 and 5), were isolated from the flower buds of Panax ginseng. The structures of the isolated compounds were elucidated on the basis of considerable spectroscopic analyses and comparison with the reported data. All six compounds were evaluated for their cytotoxicties against three human cancer cell lines, HL-60, MGC80-3 and Hep-G2.

[Chemical constituents of liquid culture of symbiotic Chaetomium globosum ML-4 of oyster and their in vitro antitumor activity].

Isolation and purification of chemical constituents of liquid culture of symbiotic Chaetomium globosum ML-4 of oyster was performed through silica gel column chromatography, gel filtration over Sephadex LH-20, preparative TLC and HPLC. Five compounds were obtained and their structures were determined as chaetoglobosin V(1), chaetoglobosin Vb(2), tyrosol(3), 5-methyluracil(4)and uracil(5), respectively, based on HR-MS and NMR data and comparison with literatures. In vitro cytotoxicity of compounds against human hepatocellular carcinoma cell line SMMC-7721 were measured byMTT method, and results showed that compound 1 could obviously inhibit the proliferation of SMMC-7721 cells with an IC₅₀ value of 60.

The Blood-Brain Barrier Permeability of Lignans and Malabaricones from the Seeds of Myristica fragrans in the MDCK-pHaMDR Cell Monolayer Model.

The blood-brain barrier (BBB) permeability of twelve lignans and three phenolic malabaricones from the seeds of Myristica fragrans (nutmeg) were studied with the MDCK-pHaMDR cell monolayer model. The samples were measured by high-performance liquid chromatography and the apparent permeability coefficients (Papp) were calculated. Among the fifteen test compounds, benzonfuran-type, dibenzylbutane-type and arylnaphthalene-type lignans showed poor to moderate permeabilities with Papp values at 10(-8)-10(-6) cm/s; those of 8-O-4'-neolignan and tetrahydrofuran-lignan were at 10(-6)-10(-5) cm/s, meaning that their permeabilities are moderate to high; the permeabilities of malabaricones were poor as their Papp values were at 10(-8)-10(-7) cm/s.

New neolignans from the seeds of Myristica fragrans that inhibit nitric oxide production.

Five new 8-O-4' type neolignans, named myrifralignan A-E (1-5), together with five known analogues (6-10), were isolated from the seeds of Myristica fragrans Houtt. Their chemical structures were determined using several spectroscopic methods. Compounds 3-10 exhibited potent inhibitory activity against the production of nitric oxide (NO) in the RAW264.

New inhibitors of nitric oxide production from the seeds of Myristica fragrans.

Six dihydrobenzofuran type neolignans were isolated from the dried ripe seeds of Myristica fragrans Houtt. (family: Myristicaceae) and their chemical structures were identified as licarin B (1), 3'-methoxylicarin B (2), myrisfrageal A (3), isodihydrocainatidin (4), dehydrodiisoeugenol (5), and myrisfrageal B (6), respectively, on the basis of spectroscopic data analyses. Among them, compounds 3 and 6 are new compounds.
