    Appendix In this Appendix biographical sketches are compiled of many scientists who have made notable contributions to the development of peptide chemistry up to its present state. We have tried to consider names mainly connected with important events during the earlier periods of peptide history, but could not include all authors mentioned in the text of this book.

  • Reflections on the Historiography of Molecular Biology
    Reflections on the Historiography of Molecular Biology HORACE FREELAND JUDSON SURELY the time has come to stop applying the word revolution to the rise of new scientific research programmes. Our century has seen many upheavals in scientific ideas--so many and so varied that the notion of scientific revolution has been stretched out of shape and can no longer be made to cover the processes of change characteristic of most sciences these past hundred years. By general consent, two great research pro- grammes arising in this century stand om from the others. The first, of course, was the one in physics that began at the turn of the century with quantum theory and relativity and ran through the working out, by about 1930, of quantum mechanics in its relativistic form. The trans- formation in physics appears to be thoroughly documented. Memoirs and biographies of the physicists have been written. Interviewswith survivors have been recorded and transcribed. The history has been told at every level of detail and difficulty. The second great programme is the one in biology that had its origins in the mid-1930s and that by 1970 had reached, if not a conclusion, a kind of cadence--a pause to regroup. This is the transformation that created molecular biology and latter-day biochemistry. The writing of its history has only recently started and is beset with problems. Accounting for the rise of molecular biology began with brief, partial, fugitive essays by participants. Biographies have been written of two, of the less understood figures in the science, who died even as the field was ripening, Oswald Avery and Rosalind Franklin; other scientists have wri:tten their memoirs.

  • Stapled Peptides—A Useful Improvement for Peptide-Based Drugs
    molecules Review Stapled Peptides—A Useful Improvement for Peptide-Based Drugs Mattia Moiola, Misal G. Memeo and Paolo Quadrelli * Department of Chemistry, University of Pavia, Viale Taramelli 12, 27100 Pavia, Italy; [email protected] (M.M.); [email protected] (M.G.M.) * Correspondence: [email protected]; Tel.: +39-0382-987315 Received: 30 July 2019; Accepted: 1 October 2019; Published: 10 October 2019 Abstract: Peptide-based drugs, despite being relegated as niche pharmaceuticals for years, are now capturing more and more attention from the scientific community. The main problem for these kinds of pharmacological compounds was the low degree of cellular uptake, which relegates the application of peptide-drugs to extracellular targets. In recent years, many new techniques have been developed in order to bypass the intrinsic problem of this kind of pharmaceuticals. One of these features is the use of stapled peptides. Stapled peptides consist of peptide chains that bring an external brace that force the peptide structure into an a-helical one. The cross-link is obtained by the linkage of the side chains of opportune-modified amino acids posed at the right distance inside the peptide chain. In this account, we report the main stapling methodologies currently employed or under development and the synthetic pathways involved in the amino acid modifications. Moreover, we report the results of two comparative studies upon different kinds of stapled-peptides, evaluating the properties given from each typology of staple to the target peptide and discussing the best choices for the use of this feature in peptide-drug synthesis. Keywords: stapled peptide; structurally constrained peptide; cellular uptake; helicity; peptide drugs 1.

  • Amino Acids-The Molecular Building Blocks of Life
    Understanding the structure-property relationships of amino acids-the molecular building blocks of life Aravindhan Ganesan Dissertation submitted in fulfillment of requirements for the degree of Doctor of Philosophy Environmental and Biotechnology Centre Faculty of Life & Social Sciences Swinburne University of Technology Victoria, Australia 2013 ©2013 Aravindhan Ganesan Abstract Amino acids are significant molecular building blocks of proteins. Only 20 natural amino acids, whose structures differ in their side chain ‘R-’ groups, control the structures, functions and selectivity of almost all the proteins in biology. The structure-properties of the amino acids must be revealed, in order to understand the methodical behind the nature’s choices in using them as ‘building blocks’. There are several molecular level details of the amino acids, which are still unknown or limitedly known. In this project, the electronic structures, properties and dynamics of the aliphatic and the aromatic amino acids under isolated and defined environmental conditions are studied quantum mechanically. A rich tool chest of ab initio and density functional theory (DFT) methods has been employed. The impacts of alkyl side chain groups on the structure-properties of the aliphatic amino acids are revealed in the gas phase. A number of properties including geometries, molecular dipole moments, ionization energies and spectra, charge re-distributions, vibrational spectra (IR and Raman), vibrational optical activity spectra (VOA), molecular orbitals and momentum spectra are investigated. Dual space analyses (DSA) has been employed as an efficient analytical tool to understand the electronic structures of the amino acids in both the coordinate space and momentum space. Our quantum chemical calculations are validated against the synchrotron-sourced and other experiments, whenever possible.

Bourses DAAD FMSH What could the ‘longue durée’ mean for the history of modern sciences? Mathias Grote N°98 | june 2015 Fernand Braudel’s concept of the longue durée is easy at hands when historians of science take into view extended periods of time. But what is exactly meant when we speak of a longue durée history of an object, instrument, concept or research field? Here, a revised meaning of the concept is proposed, which takes into account the historical observer and the background, which in the case of recent science is provided mostly by developmental narratives. Thus, a perceived longue durée could refer to historical episodes marked by continuity in the sense of a “contemporary of the non- contemporary” (Gleichzeitigkeit des Ungleichzeitigen, R. Koselleck).

  • By Gunther Hirschfelder, Manuel Trummer There Is Scarcely An
    by Gunther Hirschfelder, Manuel Trummer There is scarcely an aspect of daily cultural practice which illustrates the processes of transformation in European culture as clearly as daily nutrition. Indeed, securing the latter was essential for the daily fight for survival right up to the mid-19th century, with large sections of the population frequently being confronted with harvest failures and food shortages resulting from wars, extreme weather, pests, fire, changes in the agrarian order, and population growth. Consequently, food and drink were central both in daily life and in the celebration of feasts, and provided an opportunity for social differentiation. The hope for better nutrition was the pri- mary impetus for many migration processes and a canvas onto which desires were projected. The "Land of Cockaigne" motif, which can be traced from the Frenchman Fabliau de Coquaignes in the 13th century to Erich Kästner's (1899–1974) children's book "Der 35. Mai oder Konrad reitet in die Südsee" (1931), is a classic example of this. TABLE OF CONTENTS 1. Introduction 2. The End of Medieval Cuisine? 3.
