Book Description
Since its inception the research area of platelet pharmacology has always been a vigorous one and it is a characteristic that new approaches to the understanding of platelet function are rapidly and thoroughly investigated. The intensity of this activity is attri butable, probably, to an appreciation by research workers in the field that a satisfactory therapeutic control of platelet function has yet to be realized. Also that if and when this problem of con trolling platelet function is achieved the benefits to clinical medicine will be immense since platelets are known to be involved in a multiplicity of events coupled within the haemostatic mechanisms and inflammatory responses. Aberrations in the behaviour of plate lets is part of the aetiology of atherosclerosis, myocardial and cerebral infarction and thrombosis. At this point in time, research in platelet function is in a particularly rapid state of flux. The recent findings of research workers active in the field and also workers investigating mechan isms of stimulus response coupling in other cells, have provided interesting insights into the generality of mechanisms involved in the function of responsive cells. One may itemize these developments as the area of cell receptor/ligand interaction, induction of cell ular response by protein phosphorylation and calcium flux. The mech anism of these latter events occurs through the activity of phospho lipase generating transient intermediates. These intermediates may act as ionophores or enzyme activators or may, in the case of eico sanoids, reinforce and make irreversible the cellular response.

Book Description
This, the 148th volume of the Handbook of Experimental Pharmacology series, focuses on the very core of pharmacology, namely receptor theory. It is fitting that the originator of receptor pharmacology, A. J. CLARK, authored the fourth volume of this series 63 years ago. In that volume CLARK further developed his version of receptor theory first described four years earlier in his classic book The Mode of Action of Drugs. An examination of the topics covered in volume 4 reveals a striking similarity to the topics covered in this present volume; pharmacologists today are still as interested in unlocking the secrets of dose-response relationships to reveal the biological and che mical basis of drug action as they were over half a century ago. Sections in that 1937 volume such as "Curves relating exposure to drugs with biological effects" and "Implications of monomolecular theory" show Clark's keen insight into the essential questions that required answers to move pharma cology forward. With the advent of molecular biological cloning of human receptors has come a transformation of receptor pharmacology. Thus the expression of human receptors into surrogate host cells helped unlock secrets of receptor mechanisms and stimulus-transduction pathways. To a large extent, this elim inates the leap of faith required to apply receptor activity of drugs tested on animal receptor systems to the human therapeutic arena. However, a new leap of faith concerning the veracity of the effects found in recombinant systems with respect to natural ones is now required.

Book Description
This successful guide assists scientists trained in molecular biology and related fields who now need to know the basic theories, principles and practical applications of pharmacology. This latest edition continues the tradition of better preparing researchers in the basics of pharmacology. With expanded hands-on exercises and the addition of Pharmacokinetics coverage, new human interest material including historical facts in pharmacology and a new section on therapeutics that will help readers identify with diseases and drug treatments.The ideal book for researchers in drug discovery who have seen their role shift from "individual" to "team player" where that team includes chemists, biologists, and others with strong, but varied, science backgrounds who must now work together toward their common pharmacology goal. At GlaxoSmithKline, a pharmaceuticals world-leader, Terry Kenakin regularly teaches a course for their research scientists and has drawn on his experience to create a pharmacology primer.*New - Latest coverage of the chemistry of drugs including expanded coverage of the pharmacokinetic discussion of druglike properties -- Increases reader understanding of necessary ADME (Absorption, Distribution, Metabolism, and Excretion) properties and increases the rate of drug approval and acceptance. *Context - Unique discussions on various drug discovery teams and the role of the chemist on those teams -- Promotes the understanding of these expanding roles and responsibilities and how to maximize the effective contributions of each matrix team member. *Real-world learning - There are hands-on exercises, with extensive answers, utilizing real data on structure activity relationships; utilization of pharmacological principles to make general statements about how changes in structure lead to changes in drug activity. + hands on exercises with extensive answers on Pharmacokinetics -- Stengthens practical application and understanding of core concepts and principles.*Study sections are organized with ASPET (American Society for Pharmacology and Experimental Therapeutics)and other international organizations -- Ensures that learning follows professional industry standards.
