Biosynthetic studies, facilitated by the use of modern  analytical techniques, have allowed researchers to purify,  identify, and handle the enzymes responsible for the complex series  of steps leading to natural compounds – an important source  of leads for drugs and therapeutics. With recent advances, chemists  frequently use biosynthetic approaches to biologically interesting  compounds. Many natural products, some with potent pharmacological  activity and of paramount practical importance, are based on  heterocyclic frameworks.
  
  Offering a guide for the development of new drugs based on these  important compounds, this book describes biosynthetic methods to  synthesize heterocyclic compounds. After an introduction discussing  synthetic pathways to illustrate the basics of biosynthesis, the  authors explain natural products in chemistry and their formation  along with important analytical methods and techniques for working  with heterocycles – including isotopic labelling, enzymes and  mutants, and pathway identification. Subsequent chapters describe  heterocycle biosynthesis starting from natural products, with  particular attention to bioactive molecules.
  
  Chemical researchers using this book come away with a number of  benefits, including: 
  •   Coverage of methods and techniques: isotopic  labelling, enzymes and mutants, and pathway identification
  •   A thorough resource of information  specifically on heterocyclic natural products and their practical  biosynthetic relevance
  •   Explanation of the role of natural products  in chemistry and their formation
  •   Discussion of gene cluster identification and  the use of biogenetic engineering in pharmaceutical application
