Foxglove (Digitalis purpurea L.) leaves are frequently confused with borage (Borago officinalis L.), which is traditionally used as a food ingredient. Due to the presence of the cardiac glycosides, mostly digitoxin, foxglove leaves are poisonous to human and may be fatal if ingested. A 55-year-old Caucasian woman complaining weakness, fatigue, nausea, and vomiting was admitted to the Emergency Department.

  • Natural and Synthetic Saponins As Vaccine Adjuvants
    Review Natural and Synthetic Saponins as Vaccine Adjuvants Pengfei Wang Department of Chemistry, University of Alabama at Birmingham, Birmingham, AL 35294, USA; [email protected] Abstract: Saponin adjuvants have been extensively studied for their use in veterinary and human vaccines. Among them, QS-21 stands out owing to its unique profile of immunostimulating activity, inducing a balanced Th1/Th2 immunity, which is valuable to a broad scope of applications in com- bating various microbial pathogens, cancers, and other diseases. It has recently been approved for use in human vaccines as a key component of combination adjuvants, e.g., AS01b in Shingrix® for herpes zoster. Despite its usefulness in research and clinic, the cellular and molecular mechanisms of QS-21 and other saponin adjuvants are poorly understood. Extensive efforts have been devoted to studies for understanding the mechanisms of QS-21 in different formulations and in different combi- nations with other adjuvants, and to medicinal chemistry studies for gaining mechanistic insights and development of practical alternatives to QS-21 that can circumvent its inherent drawbacks. In this review, we briefly summarize the current understandings of the mechanism underlying QS-21’s adjuvanticity and the encouraging results from recent structure-activity-relationship (SAR) studies. Keywords: adjuvant; saponin; mechanism; SAR; QS-21; VSA-1; VSA-2 1. Introduction Traditional vaccines are whole-organism-based, using live attenuated or inactivated Citation: Wang, P. Natural and viruses or bacteria. These vaccines are quite reactogenic due to the presence of numerous Synthetic Saponins as Vaccine pathogen-associated-molecular-patterns (PAMPs) that are responsible for activation, and Adjuvants.

  • Mechanistic Investigation of Interactions Between Steroidal
    Article pubs.acs.org/JPCB Mechanistic Investigation of Interactions between Steroidal Saponin Digitonin and Cell Membrane Models Nataliya Frenkel,†,‡,# Ali Makky,†,#,⊥ Ikhwan Resmala Sudji,§ Michael Wink,*,§ and Motomu Tanaka*,†,‡,∥ † § Physical Chemistry of Biosystems, Institute of Physical Chemistry and Institute of Pharmacy and Molecular Biotechnology, Heidelberg University, D69120 Heidelberg, Germany ‡ Institute for Toxicology and Genetics, Karlsruhe Institute for Technology, D76021, Karlsruhe, Germany ∥ Institute for Integrated Cell-Material Sciences (WPI iCeMS), Kyoto University, 606-8501 Kyoto, Japan ABSTRACT: Digitonin is an amphiphilic steroidal saponin, a class of natural products that can bind to cholesterol and lyse cells. Despite the known cell membrane lysis activity, it remains unclear how it interacts with cell membranes. In the present work, the interaction mechanism between digitonin and cell membrane models has quantitatively been investigated using a combination of physical techniques. It has been demonstrated that digitonin molecules bind specifically to cholesterol in the membrane, resulting in the formation of cholesterol−digitonin complexes on the membrane surface by removing cholesterol from the membrane core. Changes in the mass density and the film mechanics caused by the digitonin were determined by using quartz crystal microbalance with dissipation (QCM-D), and the combination of X-ray reflectivity (XRR) and dual polarization interferometry (DPI) yielded the hydration level of the cholesterol−digitonin complexes.

  • Digitalis Therapy in Patients with Congestive Heart Failure
    Volume 3, Issue 2, July – August 2010; Article 016 ISSN 0976 – 044X DIGITALIS THERAPY IN PATIENTS WITH CONGESTIVE HEART FAILURE Dr. B. Anil Reddy Maheshwara College of Pharmacy, Department of Pharmaceutical sciences, Hyderabad, Andhra Pradesh. Email: [email protected] ABSTRACT Herbal Medicine, sometimes referred to as Herbalism or Botanical Medicine, is the use of herbs for their therapeutic or medicinal value. An herb is a plant or plant part valued for its medicinal, aromatic or savory qualities. Herb plants produce and contain a variety of chemical substances that act upon the body. The term digitalis or digitalis compounds are all used to refer to the entire group of inotropic (or drugs that increase myocaridal contractility). All glycosides have a shared structure of: an aglycone ring structure. The aglycone ring is where the pharmacological activity is found. The main use of Digitalis Purpurea today is as a effective way of treating congestive heart failure. As a group they are classified as cardiac inotropes. Cardiac, of course, refers to the heart. An inotrope is a substance that has a direct effect on muscle contraction. Positive inotropism is an increase in the speed and strength of muscle contraction, while negative inotropism is the opposite. Digitalis has a positive inotropic effect on the heart muscle. During the early 20th century, the drug was introduced as treatment of atrial fibrillation. Only subsequently was the value of digitalis for the treatment of congestive heart failure (CHF) established. Keywords: Digitalis, Congestive heart failure, Therapy. INTRODUCTION treatise entitled, "The Foxglove and an Account of its Medical Properties, with Practical Remarks on Dropsy." Herbal medicine is the oldest form of healthcare known to His explanations of the effects of foxglove on the heart mankind.

  • Investigation of Glycosyltransferases from Oat
    Investigation of glycosyltransferases from oat Thomas LOUVEAU A thesis submitted to the University of East Anglia for the degree of Doctor of Philosophy University of East Anglia John Innes Centre Norwich, the United Kingdoms © October 2013 © This copy of the thesis has been supplied on condition that anyone who consults it is understood to recognise that its copyright rests with the author and that use of any information derived there-from must be in accordance with current UK Copyright Law. In addition, any quotation or extract must include full attribution. I Abstract Plants produce a diversity of secondary metabolites crucial for their survival into specific ecological niches. Many of these compounds are glycosides generated by the action of family one UDP-dependant glycosyltransferases (UGTs). Glycosylated products of UGTs are known to be essential for reproductive fitness, defence against pathogens, and signalling; UGTs also have a role in the detoxification of xenobiotics. To date, little is known about monocot UGTs compare to their dicot counterparts, despite their potential role in defence and modification of health-promoting component of cereals essential to human diet. This thesis focuses on identification and functional investigation of UGTs expressed in in the diploid oat species Avena strigosa. Chapters 1 and 2 consist of the General Introduction and Material and Methods, respectively. In chapter 3, a systematic analysis of root-expressed UGTs was carried out using transcriptomic and proteomic approaches. A subset of UGTs was then selected for biochemical analysis. Of particular interest were candidates for glycosylation of avenacin, an antimicrobial triterpenoid glycoside that protects oat against fungi infection.

  • Evidence for a Cardenolide Carrier in Oncopeltus Fasciatus
    Evidence for a Cardenolide Carrier in Oncopeltus fasciatus (Dallas) (Insecta: Hemiptera) Andreas Detzel and Michael Wink Universität Heidelberg, Institut für Pharmazeutische Biologie, Im Neuenheimer Feld 364, D-69120 Heidelberg, Bundesrepublik Deutschland Z. Naturforsch. 50c, 127-134 (1995); received October 10/November 18, 1994 Oncopeltus fasciatus, Chemical Defence, Cardenolide Sequestration, Carrier-Mediated Uptake, Cardenolide Carrier Oncopeltus fasciatus (Hemiptera) is morphologically and physiologically adapted to seques­ ter cardiac glycosides for its chemical defence against predators. As a prerequisite for carde­ nolide utilization this bug has to take up and store the dietary cardenolides. Using isolated midguts it could be shown experimentally that the resorption of [ 3H]digoxin is time-, and temperature- dependent. The hydrogen ion concentration for uptake is optimal between pH 5.5 and 7 and an activation energy of 45 to 49 kJ/mol can be derived from an Arrhenius plot. Uptake can be inhibited competitively by the polar cardiac glycoside convallatoxin. Sulf- hydryl group reagents (N-ethylmaleimide), membrane destabilizing compounds and respira­ tory chain inhibitors reduce digoxin resorption, as do inhibitors of sugar transport (e.g., phlo- ridzin). The experimental data thus provide evidence for a cardenolide carrier in midgut cells of O. fasciatus.

It could be shown experimentally that car- metabolites, such as alkaloids, terpenoids and denolide-rich milkweed bugs may become dis­ glycosides, many of which serve as antiherbivoral tasteful for predators (Scudder et al., 1986) similar or antimicrobial defence compounds (Wink, 1988; to the situation in cardenolide-storing monarch Harborne, 1993; Bernays and Chapman, 1994).

  • High-Throughput Screening Identifies Cardiac
    Cancer Therapy: Preclinical High-Throughput Screening Identifies Cardiac Glycosides as Potent Inhibitors of HumanTissue Kallikrein Expression: Implications for Cancer Therapies Ioannis Prassas,1, 2 Miltiadis Paliouras,1, 2 Alessandro Datti,3 and Eleftherios P. Diamandis1, 2 Abstract Purpose: Human tissue kallikreins (KLK) comprise a subgroup of15homologous secreted serine proteases. Primarily known for their clinical use as cancer biomarkers (e.g., PSA), KLKs have recently been directly implicated in cancer-related processes, including invasion, angiogenesis, and tumor growth regulation. Therefore, the identification of compounds that would modulate expression of KLKs might be of considerable therapeutic value. Experimental Design: A cell-based high-throughput screening (HTS) of three small molecule libraries (f4,500 compounds) was undertaken; KLK expression in the breast cancer cell line MDA-MB-468 was assessed with sensitive ELISAs. Results: The initial screening resulted in 66 ‘‘putative hits’’ that decreased KLK5 expression by at least 50% over control. Secondary screening and mini-dose-response assays resulted in 21 ‘‘validated hits.’’ These 21 compounds were clustered in only three distinct functional families and were further analyzed in vitro to determine their effectiveness (IC50s). Hits that failed to show dose-responsiveness or interfered with the viability of the cells were excluded. Multiple members of the cardiac glycoside family were found to be novel inhibitors of KLK expression, acting at low concentrations (10-50 nmol/L). Furthermore, members of the same family induced marked decreases in c-MYC and c-FOS expression, in a dose-dependent manner that correlated the KLK inhibition, suggesting a transcriptional mechanism of regulation of KLK expression. Conclusions: We conclude that cardiac glycosides can dramatically suppress the transcription of KLKs and that these effects may be linked to proto-oncogene (c-myc/fos) expression.
