Abstract
The complexity of the blood-brain barrier (BBB) and neurovascular unit (NVU) was and still is a challenge to bridge. A highly selective, restrictive and dynamic barrier, formed at the interface of blood and brain, the BBB is a "gatekeeper" and guardian of brain homeostasis and it also acts as a "sensor" of pathological events in blood and brain. The majority of brain and cerebrovascular pathologies are associated with BBB dysfunction, where changes at the BBB can lead to or support disease development. Thus, an ultimate goal of BBB research is to develop competent and highly translational models to understand mechanisms of BBB/NVU pathology and enable discovery and development of therapeutic strategies to improve vascular health and for the efficient delivery of drugs. This review article focuses on the progress being made to model BBB injury in cerebrovascular diseases in vitro.

The Use of Natural Agents to Counteract Telomere Shortening: Effects of a Multi-Component Extract of Astragalus mongholicus Bunge and Danazol. Biomedicines 2020; 8:biomedicines8020031. [PMID: 32059353 PMCID: PMC7168059 DOI: 10.3390/biomedicines8020031] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2019] [Revised: 02/06/2020] [Accepted: 02/07/2020] [Indexed: 12/16/2022] Open
Abstract
A link between telomere shortening and oxidative stress was found in aging people and patients with cancer or inflammatory diseases. Extracts of Astragalus spp. are known to stimulate telomerase activity, thereby compensating telomere shortening. We characterized a multi-component hydroethanolic root extract (HRE) of Astragalus mongholicus Bunge and assessed its effects on telomeres compared to those of danazol. Astragalosides I to IV, flavonoids, amino acids and sugars were detected in the HRE. Samples of peripheral blood lymphocytes with short telomeres from 18 healthy donors (mean age 63.5 years; range 32–86 years) were exposed to a single dose of 1 µg/mL HRE or danazol for three days. Telomere length and telomerase expression were then measured. Significant elongation of telomeres associated to a less toxicity was observed in lymphocytes from 13/18 donors following HRE treatment (0.54 kb (0.15–2.06 kb)) and in those from 9/18 donors after danazol treatment (0.95 kb (0.06–2.06 kb)). The rate of cells with short telomeres (<3 kb) decreased in lymphocytes from all donors after exposure to either HRE or danazol, telomere elongation being telomerase-dependent. These findings suggest that the HRE could be used for the management of age-related diseases.

Comparative pharmacokinetic study on three formulations of Astragali Radix by an LC-MS/MS method for determination of formononetin in human plasma. Biomed Chromatogr 2019; 33:e4563. [PMID: 31025385 DOI: 10.1002/bmc.4563] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2019] [Revised: 04/01/2019] [Accepted: 04/17/2019] [Indexed: 12/11/2022]
Abstract
Astragali Radix (AR) is a widely used traditional Chinese medicine for healing the cardiovascular, liver and immune systems. Recently, superfine pulverizing technology has been applied to developing novel formulations to improve bioavailability of the active constituents in herbs, such as ultrafine granular powder of AR. In this study, a universal and sensitive quantitative method based on LC-MS/MS was employed for determining formononetin, the main flavonoid in AR, in human plasma for comparative pharmacokinetics of three oral formulations of AR. Formononetin and IS (quercetin) were extracted by ethyl acetate from human plasma and were separated on a C18 column with a mobile phase consisting of acetonitrile and 0.1% formic acid. Positive-ion electrospray-ionization mode was applied in mass spectrometric detection. The quantitative method was validated with regards to selectivity, linearity, accuracy and precision, matrix effect, extraction recovery and stability, and was applied to comparing the pharmacokinetics of ultrafine granular powder (UGP), ultrafine powder (UP) and traditional decoction pieces (TDP) of AR after oral administration. The peak concentration and areas under the concentration-time curve of formononetin in UGP and UP were significantly higher than those of TDP. UGP and UP could significantly improve the bioavailability of AR in human compared with TDP after oral administration.

Effects of astragalus injection on different stages of early hepatocarcinogenesis in a two-stage hepatocarcinogenesis model using rats. J Toxicol Pathol 2019; 32:155-164. [PMID: 31402807 PMCID: PMC6682553 DOI: 10.1293/tox.2019-0006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2019] [Accepted: 03/12/2019] [Indexed: 12/18/2022] Open
Abstract
To clarify the suppressive effects of astragalus injection (AI) on different stages of
early hepatocarcinogenesis induced by weak promotion, SD rats initiated with a single
intraperitoneal (i.p.) injection of N-diethylnitrosamine (DEN) at 200
mg/kg body weight and promoted with 0.5% piperonyl butoxide (PBO) in diet were repeatedly
administered AI at 5 ml/kg body weight/day in the early postinitiation (EPI) or late
postinitiation (LPI) period for 2 or 8 weeks, respectively. The number and area of
glutathione S-transferase placental form (GST-P)-immunoreactive
(+) foci tended to increase in the DEN+PBO group compared with the DEN-alone
group. Among the PBO-promoted groups, number and area of GST-P+ foci did not
visibly change in the DEN+PBO+AI-EPI group compared with the DEN+PBO group. In contrast,
number and area of GST-P+ foci tended to decrease in the DEN+PBO+AI-LPI group
compared with the DEN+PBO group. Number of Ki67+ cells was increased in the
DEN+PBO group compared with the DEN-alone group and was decreased in both AI-administered
groups compared with the DEN+PBO group. Gene expression analysis revealed that the
DEN+PBO+AI-LPI group showed increased transcript levels of Ccne1,
Cdkn1b, Rb1, Bax,
Bcl2, Casp3, and Casp9 compared with
the DEN+PBO group; however, the DEN+PBO+AI-EPI group did not show changes in the
transcript levels of any genes examined compared with the DEN+PBO. These results suggest
that AI administration during the LPI period caused weak suppression of
hepatocarcinogenesis under weak promotion with a low PBO dose by the mechanism involving
facilitation of cell cycle suppression causing G1/S arrest and apoptosis via the
mitochondrial pathway. In addition, the results suggest that AI administration during the
EPI period has no effect on weakly promoted hepatocarcinogenesis.

Abstract
Radix Astragali (RA) is one of the most widely used Chinese herbs prescribed in many Chinese formulas to reinforce 'Qi' and treat vital energy deficiency. This study combined fingerprinting with quantitative analysis multi-components by a single marker (QAMS) to improve the quality control standard for RA on the basis of existing quality control methods of traditional Chinese medicinal materials. UPLC-ESI-TOF-MS technique was used to evaluate the quality of RA by fingerprinting and QAMS. Using the anti-inflammatory, anti-oxidation and anti-anoxic activities to screen characteristic components of RA, the calycosin-7-O-β-d-glucoside (CG), ononin, astragaloside IV, astragaloside II, calycosin and astrageloside I significantly inhibited ear edema in mice, the calycosin and CG had good antioxidant activity and the astragaloside I had a significant anti-hypoxia activity. Astragaloside I, astragaloside II, astragaloside IV, ononin, calycosin and CG had significant pharmacological actions. These components were comprehensively used as the indicative components for the quality control of RA. Astragaloside I was used as the internal standard of the relative correction factors of CG (13.45), ononin (0.51), calycosin (12.08), astragaloside IV (0.73) and astragaloside II (0.81). Astragaloside I and CG were used as internal standards of the relative correction factors of the flavonoids and saponins of ononin (1.11), calycosin (0.04), astragaloside IV (0.73) and astragaloside II (0.81). The study combined fingerprinting with QAMS to improve the quality control standard for RA.

Abstract
Astragali Radix (AR), a Chinese materia medica (CMM) known as Huangqi, is an important medicine prescribed in herbal composite formulae (Fufang) by Traditional Chinese medicine (TCM) practitioners for thousands of years. According to the literature, AR is suggested for patients suffering from “Qi”- and “Blood”-deficiencies, and its clinical effects are reported to be related to anti-cancer cell proliferation, anti-oxidation, relief of complications in cardiovascular diseases, etc. The underlying cell signaling pathways involved in the regulation of these various diseases are presented here to support the mechanisms of action of AR. There are two botanical sources recorded in China Pharmacopoeia (CP, 2015): Astragalus membranaceus (Fisch.) Bge. Var. mongohlicus, (Bge.) Hsiao, and Astragalus membranaceus (Fisch.) Bge. (Fam. Leguminosae), whose extracts of dried roots are processed via homogenization-assisted negative pressure cavitation extraction. Geographic factors and extraction methods have impacts on the pharmaceutical and chemical profiles of AR. Therefore, the levels of the major bioactive constituents of AR, including polysaccharides, saponins, and flavonoids, may not be consistent in different batches of extract, and the pharmaceutical efficacy of these bioactive ingredients may vary depending on the source. Therefore, the present review mainly focuses on the consistency of the available sources of AR and extracts and on the investigation of the biological functions and mechanisms of action of AR and of its major bioactive constituents. Furthermore, it will also include a discussion of the most popular AR composite formulae to further elucidate their chemical and biological profiles and understand the pharmaceutical value of AR.

Abstract
Aging is a process characterized by accumulating degenerative damages, resulting in the death of an organism ultimately. The main goal of aging research is to develop therapies that delay age-related diseases in human. Since signaling pathways in aging of Caenorhabditis elegans (C. elegans), fruit flies and mice are evolutionarily conserved, compounds extending lifespan of them by intervening pathways of aging may be useful in treating age-related diseases in human. Natural products have special resource advantage and with few side effect. Recently, many compounds or extracts from natural products slowing aging and extending lifespan have been reported. Here we summarized these compounds or extracts and their mechanisms in increasing longevity of C. elegans or other species, and the prospect in developing anti-aging medicine from natural products.

[PMID: 26805467 DOI: 10.1016/j.jep.2016.01.031] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/13/2015] [Revised: 01/08/2016] [Accepted: 01/20/2016] [Indexed: 06/05/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Astragali radix ("Huang Qi" in Chinese, HQ) is a well-known traditional Chinese herbal medicine that possesses various biological functions. Astragaloside IV (AS-IV), calycosin (CS), and formononetin (FMNT) are the three main bioactive compounds of HQ that are responsible for its pharmacological activities and therapeutic efficacy. AIM OF THE STUDY This study aims to investigate the effects of HQ, AS-IV, CS, and FMNT on major human drug-metabolizing enzymes (DMEs), including CYP3A4, CYP2B6, CYP2E1, UGT1A, UGT1A6, SULT1A1, and SULT1A3, as well as efflux transporters (ETs), including P-gp, MRP2, BCRP, MRP1, and MRP3, by using HepG2 cell line. Results would provide beneficial information for the proper clinical application of HQ. MATERIALS AND METHODS HepG2 cells were treated with HQ, AS-IV, CS, and FMNT for 96h. Cell viability was examined by MTT assay. The protein and mRNA levels of DMEs and ETs were measured using Western blot and real-time PCR, respectively. RESULTS Compared with the control group, HQ considerably increased the expression levels of CYP3A4, CYP2B6, CYP2E1, UGT1A, P-gp, MRP2, BCRP, and MRP3 in a dose-dependent manner. Inversely, HQ significantly decreased the protein levels of UGT1A6, SULT1A1, and MRP1. Exposure to AS-IV induced the protein levels of UGT1A, P-gp, MRP1, and MRP3, but produced inhibitory effects on CYP3A4, CYP2B6, and BCRP. The expression levels of CYP3A4, UGT1A, SULT1A1, P-gp, MRP2, and MRP3 were remarkably increased in the CS-treated cells, whereas the protein levels of SULT1A3 and BCRP were decreased. FMNT treatment induced the protein levels towards CYP3A4, CYP2B6, UGT1A, P-gp, MRP1, MRP2, and MRP3, but inhibited the expression of CYP2E1, SULT1A1, and SULT1A3. CONCLUSIONS HQ and its main bioactive compounds, including AS-IV, CS, and FMNT significantly regulated the expression of the major DMEs and ETs. HQ produced stronger regulations (induction or inhibition) on DMEs and ETs than AS-IV, CS, or FMNT alone. The results indicate that potential drug-drug interactions might exist when the tested drugs, specifically HQ, are co-administered with other substrate drugs that are metabolized or transported via the studied DMEs or ETs. This study provides beneficial information for appropriate use of HQ for clinical therapy.

Study of pharmacokinetic profiles and characteristics of active components and their metabolites in rat plasma following oral administration of the water extract of Astragali radix using UPLC-MS/MS. JOURNAL OF ETHNOPHARMACOLOGY 2015; 169:183-194.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Astragali radix is one of the well-known traditional Chinese herbal medicine, and possesses various biological functions, such as hepatoprotective and anticancer. In present study, to investigate the metabolism and pharmacokinetics of the major constituents of A. radix, a sensitive ultra-performance liquid chromatography-electrospray ionization-mass spectrometry (UPLC-MS/MS) method with shorter chromatographic running time was developed and validated for simultaneous quantification of formononetin, ononin, calycosin, calycosin-7-β-glucoside, astragaloside IV and their glucuronide metabolites in rat plasma after oral administration of water extract of A. radix at two different doses. MATERIALS AND METHODS The chromatographic separation was achieved on a C18 column with gradient elution by using a mixture of 0.1% formic acid aqueous solution and acetonitrile as the mobile phase at a flow rate of 0.3mL/min. A tandem mass spectrometric detection was conducted using multiple-reaction monitoring (MRM) via electrospray ionization (ESI) source in positive ionization mode. Samples were pre-treated by a single-step protein precipitation with methanol, and erlotinib was used as internal standard (IS). RESULTS The current UPLC-MS/MS assay was validated for linearity, intra-day and inter-day precisions, accuracy, extraction recovery, matrix effects and stability. The lowest limit of quantifications (LLOQ) were 1ng/mL for all analytes. After oral administration, the plasma concentrations of the glucuronides, especially calycosin-3'-glucuronide, were much higher than the parent compounds. The mean half-life (t1/2) was between 1 and 5h, and the metabolites were eliminated faster than the parent constituents. The median (range) time to reach maximum plasma concentration (Tmax) was between 0.5 and 1h. CONCLUSIONS This is the first study of the pharmacokinetic study of bioactive compounds and their glucuronides in male rat plasma after oral administration of water extract of A. radix. The results demonstrated the biotransformation between the bioactive isoflavonoids and their glucuronides was extensive in rats and provided a significant basis for better understanding the absorption and metabolism mechanism of A. radix. Furthermore, this study could suggest that future studies should focus on the metabolites and biotransformation between the bioactive constituents when conducting a drug efficacy study.

Abstract
This review of simple indolizidine and quinolizidine alkaloids (i.e., those in which the parent bicyclic systems are in general not embedded in polycyclic arrays) is an update of the previous coverage in Volume 55 of this series (2001). The present survey covers the literature from mid-1999 to the end of 2013; and in addition to aspects of the isolation, characterization, and biological activity of the alkaloids, much emphasis is placed on their total synthesis. A brief introduction to the topic is followed by an overview of relevant alkaloids from fungal and microbial sources, among them slaframine, cyclizidine, Steptomyces metabolites, and the pantocins. The important iminosugar alkaloids lentiginosine, steviamine, swainsonine, castanospermine, and related hydroxyindolizidines are dealt with in the subsequent section. The fourth and fifth sections cover metabolites from terrestrial plants. Pertinent plant alkaloids bearing alkyl, functionalized alkyl or alkenyl substituents include dendroprimine, anibamine, simple alkaloids belonging to the genera Prosopis, Elaeocarpus, Lycopodium, and Poranthera, and bicyclic alkaloids of the lupin family. Plant alkaloids bearing aryl or heteroaryl substituents include ipalbidine and analogs, secophenanthroindolizidine and secophenanthroquinolizidine alkaloids (among them septicine, julandine, and analogs), ficuseptine, lasubines, and other simple quinolizidines of the Lythraceae, the simple furyl-substituted Nuphar alkaloids, and a mixed quinolizidine-quinazoline alkaloid. The penultimate section of the review deals with the sizable group of simple indolizidine and quinolizidine alkaloids isolated from, or detected in, ants, mites, and terrestrial amphibians, and includes an overview of the "dietary hypothesis" for the origin of the amphibian metabolites. The final section surveys relevant alkaloids from marine sources, and includes clathryimines and analogs, stellettamides, the clavepictines and pictamine, and bis(quinolizidine) alkaloids.

The role of polyphenols in the modulation of sirtuins and other pathways involved in Alzheimer's disease. Ageing Res Rev 2013; 12:867-83. [PMID: 23831960 DOI: 10.1016/j.arr.2013.06.003] [Citation(s) in RCA: 84] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2013] [Revised: 06/18/2013] [Accepted: 06/25/2013] [Indexed: 02/08/2023]
Abstract
Alzheimer's disease (AD) is characterised by extracellular amyloid deposits, neurofibrillary tangles, synaptic loss, inflammation and extensive oxidative stress. Polyphenols, which include resveratrol, epigallocatechin gallate and curcumin, have gained considerable interest for their ability to reduce these hallmarks of disease and their potential to slow down cognitive decline. Although their antioxidant and free radical scavenging properties are well established, more recently polyphenols have been shown to produce other important effects including anti-amyloidogenic activity, cell signalling modulation, effects on telomere length and modulation of the sirtuin proteins. Brain accessible polyphenols with multiple effects on pathways involved in neurodegeneration and ageing may therefore prove efficacious in the treatment of age-related diseases such as AD, although the evidence for this so far is limited. This review aims to explore the known effects of polyphenols from various natural and synthetic sources on brain ageing and neurodegeneration, and to examine their multiple mechanisms of action, with an emphasis on the role that the sirtuin pathway may play and the implications this may have for the treatment of AD.

Abstract
In mammals, maintenance of the linear chromosome ends (or telomeres) involves faithful replication of genetic materials and protection against DNA damage signals, to ensure genome stability and integrity. These tasks are carried out by the telomerase holoenzyme and a unique nucleoprotein structure in which an array of telomere-associated proteins bind to telomeric DNA to form special protein/DNA complexes. The telomerase complex, which is comprised of telomeric reverse transcriptase (TERT), telomeric RNA component (TERC), and other assistant factors, is responsible for adding telomeric repeats to the ends of chromosomes. Without proper telomere maintenance, telomere length will shorten with successive round of DNA replication due to the so-called end replication problem. Aberrant regulation of telomeric proteins and/or telomerase may lead to abnormalities that can result in diseases such as dyskeratosis congenita (DC) and cancers. Understanding the mechanisms that regulate telomere homeostasis and the factors that contribute to telomere dysfunction should aid us in developing diagnostic and therapeutic tools for these diseases.
