During the last decade physical and chemical methods have improved rapidly - a fact which allowed the mode of action of antibiotics to be studied - and many biochemically-oriented scientists have devoted their research to the following questions: 1. What is the metabolic pathway that is inhibited selectively, and what are the target molecules within a sensitive cell? 2. What are the relationships between the chemical structure of an antibiotic and the physicochemical properties of the sensitive mole cule(s)? 3. Why and how far is the action selective? 4. Is it possible to correlate the interaction with the target mole cule(s) with the particular biological activities observed? This monograph deals with those antibiotics which interfere with the biosynthesis of nucleic acids. The idea was to provide an insight into how to investigate the preceding questions experimentally and to solve as yet unresolved problems rather than to give a review of the current state of knowledge. Although the biochemistry of nucleic acid synthesis is known in general, the precise molecular mechanisms by which deoxyribonucleic acid is replicated or transcribed has still to be clarified. For this reason it is not yet possible to describe the molecular mechanisms by which the inhibitors of nucleic acid and protein synthesis exhibit their effects. The fact that the inhibitors of nucleic acid and protein synthesis themselves served as useful tools to obtain an insight into the mechanisms of replication, transcription and translation was one of the most exciting discoveries in this field.

This textbook builds on the success of the earlier edition, offering alternative strategies for discovering new antibiotics. It discusses how the various types of antibiotics and related drugs work to cure infections. Then it delves into the very serious matter of how bacteria are becoming resistant to these antibiotics. It also covers the global action plan on antimicrobial resistance from the World Health Organization and discusses several Antibiotic Stewardship Programs adopted by agencies at local levels. Appropriate for a one-semester course at either the graduate or advanced undergraduate level, the book is self-contained and written in accessible language. It includes all necessary background biochemistry material and a discussion of the latest developments in the field of antibiotics. Original research works are frequently cited and experimental procedures and interpretation of results are emphasized.

The rationale for the design of structural analogues of a normal metabolite is that such compounds may interfere in the utilization or function of the metabolite. A compound which is effective in this respect may be called an antimetabolite. To be successful in chemotherapy of bacterial, viral, or tumor growth, an antimetabolite should adversely affect some vital metabolic reactions in the parasite or parasitic tissue without seriously endangering the host tissue. If a metabolic process of the offending growth is different from that of the host, it is likely that the metabolism or activity of a compound, structurally related to a metabolite involved in that process, will also be different in these cells. Such differences are useful for devising effective drugs with selective actions. Sulfanilamide, a structural analogue of para aminobenzoic acid, interferes with the utilization of this metabolite in the synthesis of folic acid, an essential factor for growth. Bacteria synthesize their own folic acid and are incapable of utilizing exogenously available folic acid. However, the situation is exactly opposite in the animal host. That is, animal tissues cannot synthesize folic acid and are absolutely dependent upon exogenous sources. These differences in metabolism make possible the use of sulfanilamide as a selective inhibitor of growth. Other antibacterial or antiparasitic drugs, such as penicillin (BURCHALL, FERONE and HITCHINGS, 1965) and inhibitors of dihydrofolate reductase (HITCHINGS and BURCHALL, 1965; HITCHINGS, 1964; BURCHALL and HITCHINGS, 1965) have analogous desirable selective toxicity effects.
