Administering a drug specifically to where it is intended to act is no easy task, since all organisms have evolved highly efficient mechanisms to rid themselves of unwanted, 'foreign' molecules. Knowledge about the abundance and specificity of the transporter molecules mediating the drug elimination can thus make the difference between ineffective and successful drug therapy. This is why the action of drug transporters is a key concern in antimicrobial therapy, cancer and many other diseases targeted by drugs. This is the first reference handbook to provide a comprehensive overview of the topic, systematically characterizing all known transporters involved in drug elimination and resistance. Combining recent knowledge on all known classes of drug carriers, from microbes to man, it begins with a look at human and mammalian transporters. This is followed by microbial, fungal and parasitic transporters with special attention given to transport across those physiological barriers relevant for drug uptake, distribution and excretion. The result is a key resource that lays the foundations for understanding and investigating the molecular mechanisms for multidrug resistance in cancer cells, microbial resistance to antibiotics and pharmacokinetics in general.Ecker, Gerhard is the author of 'Transporters as Drug Carriers: Structure, Function, Substrates (Methods and Principles in Medicinal Chemistry)', published 2009 under ISBN 9783527316618 and ISBN 3527316612.
