By J. H. Exton (auth.), Dr. John W. Kebabian, Professor Dr. James A. Nathanson (eds.)

Cyclic nucleotides are in detail all in favour of the results of both stimulation or blockade of receptors; for that reason, an figuring out of the biochemistry of cyclic nucleotides must be very important for pharmacologists. Pharmacology is a technological know-how that between different issues investigates chemicals that impact the body structure of cells, tissues and organs. usually pharmacologists account for the impression of low concentrations of a drug upon a tissue through invoking the presence of a receptor upon the skin of the mobile. conventional pharmacologists excelled at picking out and classifying the houses of receptors. A. J. CLARK'S monograph within the past sequence of the instruction manual of Experimental Pharmacology (CLARK 1937) summarized the maths underlying the conventional pharmacological strategy in the direction of receptors. through its nature, although, vintage pharmacology supplied little precious information regarding the intracellular occasions taking place by reason of occupying a receptor; for instance, ALQUIST (1948) pointed out the beta-adrenocep­ tor, yet he didn't offer any perception into how stimulation of the receptor produces tissue-specific physiological responses. the invention of cyclic AMP by means of RALL and SUTHERLAND (see RALL, Vol. I) ended in biochemical investigations of many alternative receptors (including ALQUIST'S beta-adrenoceptor) that percentage a cyclic nucleotide as a standard consider the biochemical mechanisms that translate the occupancy of receptors into physiological results. Ten years in the past, within the creation to their monograph on cyclic nucleotides, ROBISON et al. (1971) commented at the speedy progress of curiosity in cyclic nucleotides over the previous years.
