  • Chemistry, Spectroscopic Characteristics and Biological Activity of Natural Occurring Cardiac Glycosides
    IOSR Journal of Biotechnology and Biochemistry (IOSR-JBB) ISSN: 2455-264X, Volume 2, Issue 6 Part: II (Sep. – Oct. 2016), PP 20-35 www.iosrjournals.org Chemistry, spectroscopic characteristics and biological activity of natural occurring cardiac glycosides Marzough Aziz DagerAlbalawi1* 1 Department of Chemistry, University college- Alwajh, University of Tabuk, Saudi Arabia Abstract:Cardiac glycosides are organic compounds containing two types namely Cardenolide and Bufadienolide. Cardiac glycosides are found in a diverse group of plants including Digitalis purpurea and Digitalis lanata (foxgloves), Nerium oleander (oleander),Thevetiaperuviana (yellow oleander), Convallariamajalis (lily of the valley), Urgineamaritima and Urgineaindica (squill), Strophanthusgratus (ouabain),Apocynumcannabinum (dogbane), and Cheiranthuscheiri (wallflower). In addition, the venom gland of cane toad (Bufomarinus) contains large quantities of a purported aphrodisiac substance that has resulted in cardiac glycoside poisoning.Therapeutic use of herbal cardiac glycosides continues to be a source of toxicity today. Recently, D.lanata was mistakenly substituted for plantain in herbal products marketed to cleanse the bowel; human toxicity resulted. Cardiac glycosides have been also found in Asian herbal products and have been a source of human toxicity.The most important use of Cardiac glycosides is its affects in treatment of cardiac failure and anticancer agent for several types of cancer. The therapeutic benefits of digitalis were first described by William Withering in 1785. Initially, digitalis was used to treat dropsy, which is an old term for edema. Subsequent investigations found that digitalis was most useful for edema that was caused by a weakened heart. Digitalis compounds have historically been used in the treatment of chronic heart failure owing to their cardiotonic effect.

  • Role of NRF2 in Lung Cancer
    cells Review Role of NRF2 in Lung Cancer Miriam Sánchez-Ortega, Ana Clara Carrera and Antonio Garrido * Department of Immunology and Oncology, Centro Nacional de Biotecnología, Consejo Superior de Investigaciones Científicas (CSIC), Universidad Autónoma de Madrid, Cantoblanco, E-28049 Madrid, Spain; [email protected] (M.S.-O.); [email protected] (A.C.C.) * Correspondence: [email protected] Abstract: The gene expression program induced by NRF2 transcription factor plays a critical role in cell defense responses against a broad variety of cellular stresses, most importantly oxidative stress. NRF2 stability is fine-tuned regulated by KEAP1, which drives its degradation in the absence of oxidative stress. In the context of cancer, NRF2 cytoprotective functions were initially linked to anti-oncogenic properties. However, in the last few decades, growing evidence indicates that NRF2 acts as a tumor driver, inducing metastasis and resistance to chemotherapy. Constitutive activation of NRF2 has been found to be frequent in several tumors, including some lung cancer sub-types and it has been associated to the maintenance of a malignant cell phenotype. This apparently contradictory effect of the NRF2/KEAP1 signaling pathway in cancer (cell protection against cancer versus pro- tumoral properties) has generated a great controversy about its functions in this disease. In this review, we will describe the molecular mechanism regulating this signaling pathway in physiological conditions and summarize the most important findings related to the role of NRF2/KEAP1 in lung cancer. The focus will be placed on NRF2 activation mechanisms, the implication of those in lung cancer progression and current therapeutic strategies directed at blocking NRF2 action.

  • Plant Ingestion: Foxglove Toxinology Scott Phillips
    Plant ingestion: foxglove toxinology Scott Phillips On our planet, there are over 1 million scientifically-named plants (only a third of which are assigned species names). And there are 7.5 billion potential consumers of these plants! Throughout the world, poisoning information centers report plant ingestion as a common exposure. In 2015, The American Association of Poison Control Centers (AAPCC) reported over 45,000 plant exposures. Counted among the top ten are cardiac glycosides (digitalis, convallarin, ouabain, oleandrin, bufadienolide, and more). Cardiac glycoside plants contain multiple and diverse glycosides. As early as the 16th century, scientists suspected Foxglove’s beneficial medical effects, although it wasn’t until January 1785 that Erasmus Darwin (Charles Darwin’s grandfather) submitted to the College of Physicians in London An Account of the Successful Use of Foxglove in Some Dropsies and in Pulmonary Consumption, and later that same year, Willian Withering published the classic text An Account of the Foxglove and some of its Medical Uses. According to anecdote, Withering substantiated his theory about the medical benefits of Foxglove after procuring a tea recipe from Mother Hutton, an herbalist physician from Shropshire, England, whose name and image pharmaceutical manufacturer Parke-Davis used nearly 150 years later in a marketing campaign. Regardless of the wellspring, Withering’s description of treating a patient with dropsy whose weak irregular pulse became regular and more forceful after receiving Foxglove started scientists down the path of using digitalis for the treatment of dropsy, Figure 1. Typical North kidney disease and other cardiac ailments. Despite American habitat of Foxglove use as a remedy for over 200 years, most recently digitalis preparations have fallen out of favor clinically because, even with adequate digitalization, heart rates did not differ between treated and untreated patients.

KEYWORDS: Bufadienolides, pharmacology, Bufo skin-secretions, toxins. INTRODUCTION Amphibians started trolling the landmasses of earth about 363 million-years-ago, with Acanthostega and Ichthyostega probably being the earliest of known amphibians (Evans[20] et al 1998). Fossil records elucidate that ancestors of modern amphibians like Frogs, Toads, Caecilians and Salamanders probably evolved about 200 million years ago during the Triassic period.

  • Quo Vadis Cardiac Glycoside Research?
    toxins Review Quo vadis Cardiac Glycoside Research? Jiˇrí Bejˇcek 1, Michal Jurášek 2 , VojtˇechSpiwok 1 and Silvie Rimpelová 1,* 1 Department of Biochemistry and Microbiology, University of Chemistry and Technology Prague, Technická 5, Prague 6, Czech Republic; [email protected] (J.B.); [email protected] (V.S.) 2 Department of Chemistry of Natural Compounds, University of Chemistry and Technology Prague, Technická 3, Prague 6, Czech Republic; [email protected] * Correspondence: [email protected]; Tel.: +420-220-444-360 Abstract: AbstractCardiac glycosides (CGs), toxins well-known for numerous human and cattle poisoning, are natural compounds, the biosynthesis of which occurs in various plants and animals as a self-protective mechanism to prevent grazing and predation. Interestingly, some insect species can take advantage of the CG’s toxicity and by absorbing them, they are also protected from predation. The mechanism of action of CG’s toxicity is inhibition of Na+/K+-ATPase (the sodium-potassium pump, NKA), which disrupts the ionic homeostasis leading to elevated Ca2+ concentration resulting in cell death. Thus, NKA serves as a molecular target for CGs (although it is not the only one) and even though CGs are toxic for humans and some animals, they can also be used as remedies for various diseases, such as cardiovascular ones, and possibly cancer. Although the anticancer mechanism of CGs has not been fully elucidated, yet, it is thought to be connected with the second role of NKA being a receptor that can induce several cell signaling cascades and even serve as a growth factor and, thus, inhibit cancer cell proliferation at low nontoxic concentrations.

  • Bufadienolides and Their Medicinal Utility: a Review
    International Journal of Pharmacy and Pharmaceutical Sciences Academic Sciences ISSN- 0975-1491 Vol 5, Issue 4, 2013 Review Article BUFADIENOLIDES AND THEIR MEDICINAL UTILITY: A REVIEW *ANJOO KAMBOJ, AARTI RATHOUR, MANDEEP KAUR Chandigarh College of Pharmacy, Landran, Mohali (Pb), India. Email: [email protected] Received: 09 Jul 2013, Revised and Accepted: 14 Aug 2013 ABSTRACT Bufadienolides are a type of cardiac glycoside originally isolated from the traditional Chinese drug Chan’Su which increases the contractile force of the heart by inhibiting the enzyme Na+/K+–ATPase. They also show toxic activities to livestock. They are widely used in traditional remedies for the treatment of several ailments, such as infections, rheumatism, inflammation, disorders associated with the central nervous system, as antineoplastic and anticancer component. Structural changes in functionality could significantly alter their cytotoxic activities. The novel oxy-functionalized derivatives of bufalin obtained could provide new platforms for combinatorial synthesis and other further investigations for the development of new bufadienolides antitumor drugs. In this review, naturally occurring bufadienolides which are isolated from both plant and animal sources are reviewed and compiled with respect to their structural changes and medicinal utility. Keywords: Bufadienolides, Cell growth inhibitory activity, Antitumor drugs, Cardenolides, Bufalin. INTRODUCTION dysfunction. Bufadienolides are a new type of natural steroids with potent antitumor activities, originally isolated from the traditional Bufadienolides are C-24 steroids; its characteristic structural feature Chinese drug Chan’Su [2-4]. They have been reported to exhibit is a doubly unsaturated six membered lactone ring having a 2- significant inhibitory activities against human myeloid leukemia pyrone group attached at the C-17β position of the cells (K562, U937, ML1, HL60), human hepatoma cells (SMMC7221), perhydrophenanthrene nucleus.
