Metabolites, enzymes, and metabolite analogues
The smallest change in the chemical constitution of a selectively toxic agent often makes an enormous change in its biological activity, and many examples of this have been given in Chapter 7. The present chapter deals in greater detail with one of these cases of high specificity, namely that arising from a close resemblance between a normal substrate of an enzyme and an agent which inhibits it. Alternatively, the resemblance may be between the agent and a coenzyme. The products of the substrates can be referred to collectively as metabolites.
