BIOPHARMACEUTICALS BIOCHEMISTRY AND BIOTECHNOLOGY

Advances in our understanding of the molecular principles underlining both health and disease has revealed the existence of many regulatory polypeptides of significant medical potential. The fact that such polypeptides are produced naturally within the body only in minute quantities initially precluded their large-scale medical application. The development in the 1970s of the twin techniques of genetic engineering and hybridoma technology marked the birth of the modern biotech era. These techniques facilitate the large-scale production of virtually any protein, and proteins of medical interest produced by these methodologies have been coined ‘biopharmaceuticals’. More recent developments in biomedical research highlights the clinical potential of nucleic acid-based therapeutic agents. Gene therapy and anti-sense technology are likely to become a medical reality within a decade. The term ‘biopharmaceutical’ now also incorporates the polynucleotide sequences utilized for such purposes.
