Foreword
The idea to publish a comprehensive overview of a number of receptor/enzyme systems and selectivity of compounds has been discussed for many years in our department. The rate at which research is advancing is so rapid that we all are regularly confronted with questions such as ‘How many receptors do actually exist?’, ‘Where are these receptors located?’ or ‘What compounds should I use?’ for those topics where we are not experts. As researchers we like to use accepted standards as well as optimal tools for our experiments. However, finding the right literature is frequently a tedious and long-winded job. Therefore we thought that a volume like this may save time and improve the quality of our work. So, this edition is intended for those colleagues who do not have time to spend many hours in the library and who do not want to wait several days for a literature search and selection of relevant information. This has been done for you by the experts in the fields! We are aware that this volume is certainly not complete. Our most difficult task has been that of selection. However, we think that we have covered such a wide range that the majority of readers will be satisfied. We are greatly indebted to all the authors who contributed to this volume and we are proud to have the support of such a distinguished group of highly qualified researchers from industry and university. Finally, we would like to thank the publishers for their cooperation and understanding during the preparation of this volume. February 1991

a-Adrenergic receptors J. C. McGrath, C. M. Brown and V. G. Wilson Institute of Physiology, University of Glasgow, Glasgow G13 8QQ, UK
SUBCLASSIFICATION On a functional basis a-adrenoceptors can be defined as receptors at which adrena¬ line and noradrenaline are agonists, phentolamine is an antagonist (pA2 7-9)and propranolol is not an antagonist (pA28) is the ubiquitous definition for al5 but is now well supported by other high-affinity, selective antagonist/ligands; within dj, 5-methyl urapidil separates a high-affinity site (pA2~9) from a low-affinity site (pA2>7.5) with several supporters; within the same d! subset, affinities for prazosin and yohimbine divide the set into two alternative subsets, djH and d1L (high and low), which do not correspond to d1A and d1B. Similarly d2 can be defined by affinity for yohimbine (pA2>7) (or its stereoisomer rauwolscine) with high-affinity supporters (and after exclusion of 5-hydroxytryptamine (5-HT) sites); within this d2 subset (binding only), prazosin separates a moderate-affinity site (pKj—7.0-7.5) and a very low-affinity site (pKt^6) with several supporters. Neither yohimbines nor imidazoline ligands bind exclusively to adrenoceptors, necessitating a broad spread of ligands in characterization studies. Molecular cloning demonstrates the existence of 3 ‘d-adrenergic receptor’ genes. These receptors have been designated oq, d2-C4 and d2-C10. The d! receptor is

a-Adrenergic receptors
[Ch. 1
coupled by a PTX(=pertussis toxin)-resistant G-protein to phospholipase C (primar¬ ily); a2-C4 and a2-C10 are coupled by a PTX-sensitive G-protein to inhibit adenylyl cyclase (primarily) and to phospholipase C. Correlation with functional subclassifi¬ cation is incomplete; a2-C10 corresponding to a2A; a! to a1A [1-3]; classification of aC4 remains to be seen. 4
LOCALIZATION Most tissues contain more than one receptor type but homogeneous exceptions to this allow clarity of definition and purification. In general ax are less common than a2 on peripheral nerves and a2-mediated smooth muscle contraction is less easy to demonstrate under standard in vitro conditions than is dj. This allows simple bioassay of agonists and antagonists for the two major subtypes at post (aj) and pre (a2) junctional sites, e.g. both in vitro and in vivo (pithed model) for rat anococcygeus (post a\), atria (chronotropic (pre a2)) and vas deferens (pre a2); similarly post a2 can be assayed on pithed rat/rabbit blood pressure or isolated rabbit ear vein [4-9].

2 P-Adrenergic receptors Martin C. Michel Department of Medicine, University of Essen, 4300 Essen 1, Germany
SUBCLASSIFICATION Historically P-adrenergic receptors have been classified into a P! and a p2 subtype, which are distinguished by the agonist order of potency isoproterenol> adrenaline-noradrenaline for pr and isoproterenol>adrenaline>noradrenaline for p2-adrenergic receptors [1], This subclassification was confirmed by the deve¬ lopment of highly subtype-selective antagonists; today the most selective antagonists available are bisoprolol and CGP 20,712A (P^ and ICI 118,551 (p2). The two receptor subtypes have beeen cloned in various species including man and the genomic counterparts of these cDNAs are located on separate human chromosomes [2]. Additionally, it has been found that the P-adrenergic receptors mediating lipolysis and gut motility are atypical (e.g. have very low affinity for standard antagonists such as propranolol) and a third cDNA has been cloned which encodes a P-adrenergic receptor sharing many similarities with the pharmacologically defined atypical p-adrenergic receptors [3,4]. Besides full agonists and pure antagonists, compounds with various degrees of intrinsic efficacy at P-adrenergic receptors have been identified. Those with a relatively high intrinsic efficacy are usually termed partial agonists whereas those with a small intrinsic efficacy are frequently called antagonists with intrinsic sympath¬ omimetic activity (ISA) [5].
LOCATION AND FUNCTION Whereas the original subclassificattion of P-adrenergic receptors assumed a high degree of tissue specificity, it is now clear that pr and p2-adrenergic receptors coexist in most tissues whereby one subtype usually dominates. Cardiac P-adrenergic receptors are predominantly of the P] subtype (^70% in atria and 80% in ventricles of the human heart) and mediate positive inotropic,

chronotropic, dromotropic and bathmotropic effects; p2-adrenergic receptors have been convincingly demonstrated in the heart of nearly all species including man but their physiological role is only poorly understood. p2-Adrenergic receptors are involved in the positive chronotropic effects of p-agonists in right atria from rats, guinea-pigs, cats, dogs and humans, but not in those of rabbits. Additionally, in the human heart p2-adrenergic receptors may be involved in positive inotropic effects of some P-agonists [6,7]. Vascular P-adrenergic receptors mediate vasodilation and are mainly of the p2 subtype, although pradrenergic receptors may prevail in some vascular beds (e.g. some coronary arteries) [8]. Renal P-adrenergic receptors are mainly of the Pi subtype. Some renal P-receptors are found in the juxtaglomerular zone and enhance renin release (most species via pr but in rabbit via p2-receptors), but the majority of renal P-adrenergic receptors are located on tubular cells; the function of tubular P-adrenergic receptors is still unclear [9]. Pulmonary P-adrenergic receptors mediate bronchorelaxation and in most spe¬ cies including man are mainly of the p2 subtype but are of the P, subtype in rabbits [10]. It should be noted that some of the p2-receptors found in lung homogenates are not derived from bronchial smooth muscle but rather from macrophages and other leucocytes (see below). Hepatic P-adrenergic receptors are predominantly of the p2 subtype and mediate glycogenolysis and gluconeogenesis [8]. Skeletal muscle also contains P-adrenergic receptors which are mainly of the p2 subtype and are involved in the regulation of cell metabolism [8]. Leucocytes and other blood cells contain a homogeneous population of P2-adrenergic receptors (in mammals) which generally mediate inhibition of the function of the respective leucocyte type such as inhibition of enzyme release, cytokine production, antibody generation and proliferation [11], Adipocytes and smooth muscle cells of the gut contain various types of p-adrenergic receptors but the subtype mediating lipolysis and gut motility appears to be atypical, i.e. neither pj nor p2. Presynaptic P-adrenergic receptors are mainly of the p2 subtype and facilitate transmitter release; evidence for presynaptic prreceptors has been presented in some model systems. In the brain postsynaptic p-adrenergic receptors exist and are believed to be involved in the regulation of various physiological processes. Additionally, it should be mentioned that p2-adrenergic receptors can mediate insulin release and hypokalaemia. SOURCES A. B. C. D. E. F.

The potency of p-adrenergic agonists can vary by 3-4 orders of magnitude among model systems and functional responses measured due to the enormous variability in post-receptor amplification mecha¬ nisms. Thus, this table gives affinities as determined from binding studies only. If classification of a certain functional response solely based on agonists is necessary, the order of potency of several such agonists should be used rather than their absolute potency. Based on the above affinities at p-adrenoceptor subtypes and other criteria, propanolol and CGP 12,177 are the non-selective antagonist of choice, with CGP 12,177 offering the additional advantage of great hydrophilicity; CGP 20,712A (in vitro) and bisoprolol (in vivo) are the prselective antagonists and ICI 118,551 is the p2-selective antagonist of choice because of their outstanding subtype selectivity. ICI 118,551 cannot be used in humans because of recent evidence that it may be carcinogenic.

3 Nicotinic receptors Ignaz Wessler Department of Pharmacology, University of Mainz, Obere Zahlbacher Str. 67, 6500 Mainz, Germany
SUBCLASSIFICATION The nicotine receptor (nAChR) is an allosteric protein shifting between multiple conformational states very rapidly. The nAChR consists of two to four different subunits (a, P, y, 5, e) and contains distinct functional domains (competitive agonist¬ binding sites, non-competitive ligand-binding sites, ion channel, immunogenic sites, phosphorylation sites). Although a complete cDNA sequencing of the subunits has been performed for some species (Torpedo californica, Torpedo marmorata, mouse, ox), the concept of subtypes of nAChR is only poorly developed. Cloning studies suggest at least five subtypes of nAChR, but a distinct classification of nAChR subtypes differing in their molecular, structural and pharmacological properties is, so far, not available. The only differentiation of nAChR subtypes which is widely accepted is the classic distinction between ganglionic (neuronal) and muscular nAChR. This concept, however, does not take into account the different molecular, electrophysiological and pharmacological properties of nAChR observed in differ¬ ent tissues. The following paragraphs briefly summarize evidence in favour of a heterogeneity of both muscular and neuronal nAChR. Muscular nAChR (electric organ and skeletal muscle) Both electric organ and muscular nAChR are composed of four different subunits (a, P, y, e or 6) and form the same quaternary structure (pentamer with four transmem¬ brane segments). Structural dissimilarities, however, have also been found, particu¬ larly in the competitive binding region of electric organ and skeletal muscle nAChR. Moreover, in skeletal muscles two different subtypes of nAChR containing different subunits are synthesized. The e-subunit, detected in calf, bovine and rat skeletal muscles, is supposed to replace the y-subunit during the formation of neuromuscular contact. Some evidence indicates that the y-containing nAChR corresponds to the extrasynaptically localized muscular nAChR.

Neuronal nAChR Neuronal nAChR differ from muscular nAChR with respect to their molecular, structural, electrophysiological and pharmacological properties, but some homolo¬ gies are also evidence (a-bungarotoxin binding sites in the brain and skeletal muscle). Neuronal nAChR appear to be composed of two different subunits (a2_4,p) only, but the exact subunit stoichiometry is unknown. Channel properties of neuronal nAChR differ from those of muscular nAChR (smaller conductance in neuronal than in muscular nAChR). At least three different subtypes of neuronal nAChR have been proposed on the basis of distinct molecular properties. The nAChR localized on cell bodies (soma of neurons in the central nervous system or ganglia in the peripheral nervous system) may be regarded as one subtype (function generally not blocked by a-bungarotoxin). A second type of neuronal nAChR is localized presynaptically, either in the peripheral nervous system at terminals of motoneurons (blockable by a-bungarotoxin) or in the central nervous system at terminals that release acetylcholine, dopamine, y-aminobutyric acid (GABA), noradrenaline or 5-hydroxytryptamine (5-HT). Evidence supporting the existence of these latter nAChR has been found in functional studies or in binding studies after respective lesion experiments. A further population of neuronal nAChR mediating depolarizaton is localized on non-myelinated nerve membranes (nodes of Ranvier, sensory nerve terminals, mammalian C-fibres, postganglionic sympathetic neurons). These nAChR, however, are pharmacologically less well characterized and probably do not represent a uniform population. For instance, it has been shown that depolarization of sympathetic neurons is blocked by hexamethonium (acting prefer¬ entially at neuronal nAChR), whereas depolarization of the pre-terminal part of motor nerves (last node of Ranvier) can be induced by decamethonium (acting preferentially at muscular nAChR). Neuronal nAChR differ also between different species (amphibians, avians, insects, mammals). Effects of agonists and antagonists at nAChR An approximate classification for agonists to mediate various biological events exists only for two actions: a preferential action at ganglia (carbachol, l,l-dimethyl-4phenylpiperazinium, lobeline, nicotine, tetramethylammonium) or at skeletal muscles (decamethonium, suxamethonium). The effects at ganglia appear to be more rapidly extinguished by desensitization than the effects at skeletal muscles. The antagonists hexamethonium, mecamylamine, neosurugatoxin, pentolinium and trimethapan are preferentially acting at ganglionic nAChR, whereas the non-depolar¬ izing muscle relaxants (alcuronium, atracurium, gallamine, pancuronium, pipecuronium, stercuronium, vecuronium) and benzoquinonium are preferentially acting at muscular nAChR. Vecuronium, however, has recently been shown to block catecho¬ lamine secretion from cultured adrenal medullary cells and neuromuscular trans¬ mission with a similar potency. Moreover, tubocurarine and dihydro-(3-erythroidine appear to have similar potencies at ganglionic and muscular nAChR. a-Neurotoxins (a-bungarotoxin, erabutoxin-b, siamensis toxin, etc.) are regarded to block exclusi¬ vely the muscular nAChR. a-Bungarotoxin, however, shows a specific binding at ganglia, the adrenal medulla and the brain, but this toxin blocks neither ganglionic transmission, nor catecholamine secretion, nor acetylcholine release from

autonomic neurons. Nevertheless, a-bungarotoxin (but not erabutoxin-b or siammensis toxin) has been shown to block some effects mediated by stimulation of neuronal nAChR (nicotinic autofacilitation of acetylcholine release from motoneur¬ ons, repetitive firing of motoneurons or of inhibitory interneurons in the rat cerebellum). K-Bungarotoxin, another a-toxin, has been reported to act as a specific antagonist at neuronal nAChR in the central and peripheral nervous system. The a-toxins bind-more or less-irreversibly to their binding sites.
LOCALIZATION The highest density of nAChR (a-bungarotoxin binding) is found in the electric organ of Torpedo californica or Torpedo marmorata (roughly 1000-fold higher than at skeletal muscles). Muscular nAChR are imbedded in the postsynaptic membrane of endplates of skeletal muscles, roughly 50 nm distant to the presynaptic membrane. Endplates are placed just in the middle of skeletal muscle fibres. Some few muscular nAChR are also present at the non-innervated part of the muscular membrane. Neuronal nAChR (peripheral nervous system) are localized at ganglia, adrenal medulla, motoneurons (terminal and axon) and non-myelinated nerve membranes. Neuronal nAChR (central nervous system) are localized at distinct areas within the brain and spinal cord. High-density binding of nicotine (rat) is found in the cerebral cortex (layers I and III/IV), substantia nigra, thalamus, superior colliculus and striatum, whereas low-level nicotine binding occurs in the hypothalamus, cerebellum and spinal cord. Nicotine binding in the spinal cord is mainly found in laminae II—III of the dorsal horn. Nicotine binding occurs also in the retina, optic nerve and optic tract. High-affinity binding for nicotine or acetylcholine shows only a small overlap (cerebral cortex (layer I) and superior colliculus) with a-bungarotoxin binding. High-density a-bungarotoxin binding occurs in the cerebral cortex (layer VI), hypothalamus, hippocampus and inferior colliculus. nAChR mediating hyper¬ polarization have also been found on cultured astrocytes.
