  • Toxicological Profile for 2-Butanone Released for Public Comment in May 2019
    Toxicological Profile for 2-Butanone October 2020 2-BUTANONE ii DISCLAIMER Use of trade names is for identification only and does not imply endorsement by the Agency for Toxic Substances and Disease Registry, the Public Health Service, or the U.S. Department of Health and Human Services. 2-BUTANONE iii FOREWORD This toxicological profile is prepared in accordance with guidelines* developed by the Agency for Toxic Substances and Disease Registry (ATSDR) and the Environmental Protection Agency (EPA). The original guidelines were published in the Federal Register on April 17, 1987. Each profile will be revised and republished as necessary. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for these toxic substances described therein. Each peer-reviewed profile identifies and reviews the key literature that describes a substance's toxicologic properties. Other pertinent literature is also presented, but is described in less detail than the key studies. The profile is not intended to be an exhaustive document; however, more comprehensive sources of specialty information are referenced. The focus of the profiles is on health and toxicologic information; therefore, each toxicological profile begins with a relevance to public health discussion which would allow a public health professional to make a real-time determination of whether the presence of a particular substance in the environment poses a potential threat to human health. The adequacy of information to determine a substance's

Currently, the etiology of these pathological features is not clearly understood and, therefore, no curative treatment is available. Since the 1990s, hydrogen sulfide (H2S) has been described as the third gasotransmitter with plethoric regulatory functions in cardiovascular tissues, especially in pulmonary circulation. Alteration in H2S biogenesis has been associated with the hallmarks of PH. H2S is also involved in pulmonary vascular cell homeostasis via the regulation of hypoxia response and mitochondrial bioenergetics, which are critical phenomena affected during the development of PH. In addition, H2S modulates + ATP-sensitive K channel (KATP) activity, and is associated with PA relaxation. In vitro or in vivo H2S supplementation exerts antioxidative and anti-inflammatory properties, and reduces PA remodeling. Altogether, current findings suggest that H2S promotes protective effects against PH, and could be a relevant target for a new therapeutic strategy, using attractive H2S-releasing molecules.

  • Folk Medicine, Phytochemistry and Pharmacological Application of Piper Marginatum
    Revista Brasileira de Farmacognosia 26 (2016) 767–779 ww w.elsevier.com/locate/bjp Review Folk medicine, phytochemistry and pharmacological application of Piper marginatum ∗ Jennifer Brú, Juan David Guzman Departamento de Química y Biología, División de Ciencias Básicas, Universidad del Norte, Barranquilla, Colombia a b s t r a c t a r t i c l e i n f o Article history: Piper marginatum Jacq., Piperaceae, is a widely distributed Neotropical species abundant in the Caribbean, Received 16 February 2016 exhibiting a characteristic winged petiole and a heart-shaped leaf, its two vegetative landmarks for rapid Accepted 31 March 2016 identification. The species has been employed by traditional indigenous cultures for its reputed medicinal properties. The plant is most frequently employed by local healers in Central America, the Antilles and Keywords: South America, for alleviating gastrointestinal ailments, administered as a decoction or infusion for its Piper marginatum tonic, diuretic and carminative effects. These beneficial properties may be attributed to the presence of Piperaceae various phytochemicals within P. marginatum, with most of the studies focusing on the essential oil of Folk medicine the plant. Monoterpenoids, sesquiterpenoids and phenylpropanoids of a varied chemical structure have Phytochemistry Pharmacology been identified in the essential oil, while phenylalkanoids, aristolactams, amides and flavonoids have been Biological applications purified by chromatographic techniques from the extracts. The biological and pharmacological exami- nation of P. marginatum showed that the plant may be a valuable source of mosquitocidal, antifungal, antitumoral and hemostatic agents. Future bioguided research may yield biologically relevant molecules useful in medicine or agriculture. © 2016 Sociedade Brasileira de Farmacognosia.
