Biopharmaceuticals: Design and Modification of Biomacromolecules

Course content

Besides an introduction to the concepts and methods that are relevant for investigating and understanding the physicochemical and pharmacological properties of macromolecules the course focuses on the design, discovery and applicability of biopharmaceutical drugs, primarily those based on peptides or proteins.

Furthermore, this course will form the basis for studies on optimization of pharmaceutical properties of peptides, proteins and nucleic acids in relation to preclinial and clinical drug development. Finally, drug leads derived from these classes of macromolecules (e.g. peptidomimetics a oligonucleotide analogues) will be discussed.

These subjects will be introduced via lectures (based on book chapters and comprehensive reviews and articles), while the class sessions will comprise student presentations and discussion of selected scientific articles in order to facilitate an in-depth understanding of both theoretical and practical aspects of biopharmaceutical drug research. In addition, some class sessions will comprise theoretical execises on the basic elements of the course (e.g. peptide synthesis and protein modification). Also, the course comprises three practical exercises in a chemical synthesis lab. These exercises illustrate basic solid-phase peptide synthesis methodology and protein modification. For each excercise a laboratory notebook should be kept in order to facilitate writing of mandatory reports, which also include answering specific questions and interpretation of analytical results (LC-MS, MALDI, and ELISA).


The most relevant compound classes and their applications are briefly outlined below:

  • Peptide- and protein-based drugs, inculding modified peptide and proteins (primary content of the course).
  • Introduction to antibodies and therapeutic relevance.
  • Introduction to oligonucleotides for gene therapy and antisense siRNA as putative biopharmaceutical drugs.
  • Introduction to vaccines.

 


Methods and concepts:

  • Importance of structure for pharmacological activity and suitable drug properties: charge, solubility, stability and delivery. 
  • Primary sequence and folding into secondary and tertiary structures and methods for manipulating these.
  • Principles of solid-phase peptide synthesis (incl. combinatorial and parallel approaches) and optimization. Advanced peptide chemistry including selection of linkers, coupling reagents and protecting groups.
  • Protein biosynthesis and modification: post-translational and chemical transformations.
  • Genetic and protein engineering as a discovery and production tool for biological protein and peptide expression and modification.
  • Practical manual solid-phase peptide synthesis and simple modification of proteins.
  • Chemical protein synthesis and semisynthesis

Learning outcome

The purpose of this course is to provide students with theoretical knowledge on biopharmaceutical drug discovery as a central part of contemporary and future interdisciplinary drug discovery efforts in academia as well as in the biotech and pharmaceutical industry. The focus will primarily be on peptides and proteins as they currently constitute the most important class of biopharmaceuticals.
An additional aim is to introduce students to methodologies related to chemical synthesis, biological expression, and modification of biopharmaceuticals with a focus on their applications in drug discovery and development.

At the end of the course, students are expected to be able to:

Knowledge

  • comprehend the steps involved in biopharmaceutical drug discovery
  • understand aspects of chemical peptide synthesis relevant for biopharmaceutical drug discovery
  • understand post-translational peptide/protein modifications
  • understand methods used in chemical peptide and protein modification
  • understand the concept of unnatural amino acid mutagenesis
  • appreciate of the potential of novel types of biopharmaceuticals (e.g. nucleic acids and analogs thereof) in sufficient detail to follow future scientific developments
