Abstract There is an unmet need in severe asthma where approximately 40% of patients exhibit poor -agonist responsiveness, suffer daily symptoms and show frequent exacerbations. 2+ Antagonists of the Ca -activated-Cl¯ channel, TMEM16A, offers a new mechanism to bronchodilate airways and block the multiple contractiles operating in severe disease. -
Folic Acid Antagonists: Antimicrobial and Immunomodulating Mechanisms and Applications
International Journal of Molecular Sciences Review Folic Acid Antagonists: Antimicrobial and Immunomodulating Mechanisms and Applications Daniel Fernández-Villa 1, Maria Rosa Aguilar 1,2 and Luis Rojo 1,2,* 1 Instituto de Ciencia y Tecnología de Polímeros, Consejo Superior de Investigaciones Científicas, CSIC, 28006 Madrid, Spain; [email protected] (D.F.-V.); [email protected] (M.R.A.) 2 Consorcio Centro de Investigación Biomédica en Red de Bioingeniería, Biomateriales y Nanomedicina, 28029 Madrid, Spain * Correspondence: [email protected]; Tel.: +34-915-622-900 Received: 18 September 2019; Accepted: 7 October 2019; Published: 9 October 2019 Abstract: Bacterial, protozoan and other microbial infections share an accelerated metabolic rate. In order to ensure a proper functioning of cell replication and proteins and nucleic acids synthesis processes, folate metabolism rate is also increased in these cases. For this reason, folic acid antagonists have been used since their discovery to treat different kinds of microbial infections, taking advantage of this metabolic difference when compared with human cells. However, resistances to these compounds have emerged since then and only combined therapies are currently used in clinic. In addition, some of these compounds have been found to have an immunomodulatory behavior that allows clinicians using them as anti-inflammatory or immunosuppressive drugs. Therefore, the aim of this review is to provide an updated state-of-the-art on the use of antifolates as antibacterial and immunomodulating agents in the clinical setting, as well as to present their action mechanisms and currently investigated biomedical applications. Keywords: folic acid antagonists; antifolates; antibiotics; antibacterials; immunomodulation; sulfonamides; antimalarial 1. -

Only benzimidazoles are currently used in mass drug administration, with many instances of reduced activity. Terpenes are a class of compounds with anthelmintic activity. Thymol, a natural monoterpene phenol, was used to help eradicate hookworms in the U.S. South circa 1910. However, the use of terpenes as anthelmintics was discontinued because of adverse side effects associated with high doses and premature stomach absorption. Furthermore, the dose–response activity of specific terpenes against STNs has been understudied. Here we used hollow, porous yeast particles (YPs) to efficiently encapsulate (>95%) high levels of terpenes (52% w/w) and evaluated their anthelmintic activity on hookworms (Ancylostoma ceylanicum), a rodent parasite (Nippostrongylus brasiliensis), and whipworm (Trichuris muris). We identified YP–terpenes that were effective against all three parasites. -

The purpose of this review is a comparative analysis of the pharmacological potential of these natural products. According to PASS (Prediction of Activity Spectra for Substances) estimates, they are more likely to exhibit antiprotozoal and antitumor properties. Some of them are now widely used in clinical medicine. All polycyclic endoperoxides presented in this article demonstrate antiprotozoal activity and can be divided into three groups. The third group includes endoperoxides, which show weak antiprotozoal activity with a reliability of up to 70%, and this group includes only 1.1% of metabolites. The second group includes the largest number of endoperoxides, Citation: Dembitsky, V.M.; which are 65% and show average antiprotozoal activity with a confidence level of 70 to 90%. Lastly, Ermolenko, E.; Savidov, N.; the third group includes endoperoxides, which are 33.9% and show strong antiprotozoal activity with Gloriozova, T.A.; Poroikov, V.V. -

Methodologically and operationally, both approaches do propose a very promising future for the development of pharmacological research, with closer links to the highly productive area of outcomes- oriented epidemiology and with the most advanced sector of basic sciences. It seems specifically important that the two areas could be developed in close interaction, possibly within the same department(s), to assure a productive interplay of competences in the collaboration with clinical care, as well as in the training of the new generations of pharmacologists, pharmacists, clinicians. PL-02 BASIC PERIPHERAL MOLECULAR COMPONENTS OF INFLAMMATORY PAIN H Ferreira School of Medicine of Ribeirão Preto. Department of Pharmacology, Campus USP, Ribeirão Preto, SP. Brazil. email: [email protected] When non steroidal anti-inflammatory drugs mechanism of action was discovered, I proposed that their analgesic effect resulted from the prevention of the nociceptor sensitization by prostaglandins. Thus, pain in an inflammatory process results from an action of mechanical, thermal or chemical stimuli upon sensitized nociceptors (hiperalgesia, hypernociception-HPr). -

Type IA Topoisomerases As Targets for Infectious Disease Treatments
microorganisms Review Type IA Topoisomerases as Targets for Infectious Disease Treatments Ahmed Seddek 1,2 , Thirunavukkarasu Annamalai 1 and Yuk-Ching Tse-Dinh 1,2,* 1 Department of Chemistry and Biochemistry, Florida International University, Miami, FL 33199, USA; asedd001@fiu.edu (A.S.); athiruna@fiu.edu (T.A.) 2 Biomolecular Sciences Institute, Florida International University, Miami, FL 33199, USA * Correspondence: ytsedinh@fiu.edu; Tel.: +1-305-348-4956 Abstract: Infectious diseases are one of the main causes of death all over the world, with antimi- crobial resistance presenting a great challenge. New antibiotics need to be developed to provide therapeutic treatment options, requiring novel drug targets to be identified and pursued. DNA topoi- somerases control the topology of DNA via DNA cleavage–rejoining coupled to DNA strand passage. The change in DNA topological features must be controlled in vital processes including DNA repli- cation, transcription, and DNA repair. Type IIA topoisomerases are well established targets for antibiotics. In this review, type IA topoisomerases in bacteria are discussed as potential targets for new antibiotics. In certain bacterial pathogens, topoisomerase I is the only type IA topoisomerase present, which makes it a valuable antibiotic target. This review will summarize recent attempts that have been made to identify inhibitors of bacterial topoisomerase I as potential leads for antibiotics and use of these inhibitors as molecular probes in cellular studies. Crystal structures of inhibitor–enzyme complexes and more in-depth knowledge of their mechanisms of actions will help to establish the structure–activity relationship of potential drug leads and develop potent and selective therapeutics that can aid in combating the drug resistant bacterial infections that threaten public health. -
Marine Pharmacology in 1999: Compounds with Antibacterial
Comparative Biochemistry and Physiology Part C 132 (2002) 315–339 Review Marine pharmacology in 1999: compounds with antibacterial, anticoagulant, antifungal, anthelmintic, anti-inflammatory, antiplatelet, antiprotozoal and antiviral activities affecting the cardiovascular, endocrine, immune and nervous systems, and other miscellaneous mechanisms of action Alejandro M.S. Mayera, *, Mark T. Hamannb aDepartment of Pharmacology, Chicago College of Osteopathic Medicine, Midwestern University, 555 31st Street, Downers Grove, IL 60515, USA bSchool of Pharmacy, The University of Mississippi, Faser Hall University, MS 38677, USA Received 28 November 2001; received in revised form 30 May 2002; accepted 31 May 2002 Abstract This review, a sequel to the 1998 review, classifies 63 peer-reviewed articles on the basis of the reported preclinical pharmacological properties of marine chemicals derived from a diverse group of marine animals, algae, fungi and bacteria. In all, 21 marine chemicals demonstrated anthelmintic, antibacterial, anticoagulant, antifungal, antimalarial, antiplatelet, antituberculosis or antiviral activities. An additional 23 compounds had significant effects on the cardiovascular, sympathomimetic or the nervous system, as well as possessed anti-inflammatory, immunosuppressant or fibrinolytic effects. Finally, 22 marine compounds were reported to act on a variety of molecular targets, and thus could potentially contribute to several pharmacological classes. Thus, during 1999 pharmacological research with marine chemicals continued
