Alprenolol: One of the ADRENERGIC BETA-ANTAGONISTS used as an antihypertensive, anti-anginal, and anti-arrhythmic agent.Amino Alcohols: Compounds possessing both a hydroxyl (-OH) and an amino group (-NH2).Sympatholytics: Drugs that inhibit the actions of the sympathetic nervous system by any mechanism. The most common of these are the ADRENERGIC ANTAGONISTS and drugs that deplete norepinephrine or reduce the release of transmitters from adrenergic postganglionic terminals (see ADRENERGIC AGENTS). Drugs that act in the central nervous system to reduce sympathetic activity (e.g., centrally acting alpha-2 adrenergic agonists, see ADRENERGIC ALPHA-AGONISTS) are included here.Adrenergic beta-Antagonists: Drugs that bind to but do not activate beta-adrenergic receptors thereby blocking the actions of beta-adrenergic agonists. Adrenergic beta-antagonists are used for treatment of hypertension, cardiac arrhythmias, angina pectoris, glaucoma, migraine headaches, and anxiety.Pindolol: A moderately lipophilic beta blocker (ADRENERGIC BETA-ANTAGONISTS). It is non-cardioselective and has intrinsic sympathomimetic actions, but little membrane-stabilizing activity. (From Martindale, The Extra Pharmocopoeia, 30th ed, p638)Practolol: A beta-1 adrenergic antagonist that has been used in the emergency treatment of CARDIAC ARRYTHMIAS.Propranolol: A widely used non-cardioselective beta-adrenergic antagonist. Propranolol has been used for MYOCARDIAL INFARCTION; ARRHYTHMIA; ANGINA PECTORIS; HYPERTENSION; HYPERTHYROIDISM; MIGRAINE; PHEOCHROMOCYTOMA; and ANXIETY but adverse effects instigate replacement by newer drugs.Pentaerythritol Tetranitrate: A vasodilator with general properties similar to NITROGLYCERIN but with a more prolonged duration of action. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1025)Receptors, Adrenergic: Cell-surface proteins that bind epinephrine and/or norepinephrine with high affinity and trigger intracellular changes. The two major classes of adrenergic receptors, alpha and beta, were originally discriminated based on their cellular actions but now are distinguished by their relative affinity for characteristic synthetic ligands. Adrenergic receptors may also be classified according to the subtypes of G-proteins with which they bind; this scheme does not respect the alpha-beta distinction.Receptors, Adrenergic, beta: One of two major pharmacologically defined classes of adrenergic receptors. The beta adrenergic receptors play an important role in regulating CARDIAC MUSCLE contraction, SMOOTH MUSCLE relaxation, and GLYCOGENOLYSIS.Isoproterenol: Isopropyl analog of EPINEPHRINE; beta-sympathomimetic that acts on the heart, bronchi, skeletal muscle, alimentary tract, etc. It is used mainly as bronchodilator and heart stimulant.Oxprenolol: A beta-adrenergic antagonist used in the treatment of hypertension, angina pectoris, arrhythmias, and anxiety.Adrenergic Uptake Inhibitors: Drugs that block the transport of adrenergic transmitters into axon terminals or into storage vesicles within terminals. The tricyclic antidepressants (ANTIDEPRESSIVE AGENTS, TRICYCLIC) and amphetamines are among the therapeutically important drugs that may act via inhibition of adrenergic transport. Many of these drugs also block transport of serotonin.Propanolamines: AMINO ALCOHOLS containing the propanolamine (NH2CH2CHOHCH2) group and its derivatives.Dihydroalprenolol: Hydrogenated alprenolol derivative where the extra hydrogens are often tritiated. This radiolabeled form of ALPRENOLOL, a beta-adrenergic blocker, is used to label the beta-adrenergic receptor for isolation and study.NADP Transhydrogenase, B-Specific: A NADP transhydrogenase subtype found in certain types of BACTERIA. This transhydrogenase uses a mechanism that transfers hydrogen to the B side of the NAD(+) or NADP(+) ring structure.Epinephrine: The active sympathomimetic hormone from the ADRENAL MEDULLA. It stimulates both the alpha- and beta- adrenergic systems, causes systemic VASOCONSTRICTION and gastrointestinal relaxation, stimulates the HEART, and dilates BRONCHI and cerebral vessels. It is used in ASTHMA and CARDIAC FAILURE and to delay absorption of local ANESTHETICS.Pentosan Sulfuric Polyester: A sulfated pentosyl polysaccharide with heparin-like properties.Adrenergic beta-2 Receptor Antagonists: Drugs that bind to and block the activation of ADRENERGIC BETA-2 RECEPTORS.Anura: An order of the class Amphibia, which includes several families of frogs and toads. They are characterized by well developed hind limbs adapted for jumping, fused head and trunk and webbed toes. The term "toad" is ambiguous and is properly applied only to the family Bufonidae.Receptors, Adrenergic, beta-2: A subclass of beta-adrenergic receptors (RECEPTORS, ADRENERGIC, BETA). The adrenergic beta-2 receptors are more sensitive to EPINEPHRINE than to NOREPINEPHRINE and have a high affinity for the agonist TERBUTALINE. They are widespread, with clinically important roles in SKELETAL MUSCLE; LIVER; and vascular, bronchial, gastrointestinal, and genitourinary SMOOTH MUSCLE.Adenylosuccinate Lyase: An enzyme that, in the course of purine ribonucleotide biosynthesis, catalyzes the conversion of 5'-phosphoribosyl-4-(N-succinocarboxamide)-5-aminoimidazole to 5'-phosphoribosyl-4-carboxamide-5-aminoimidazole and the conversion of adenylosuccinic acid to AMP. EC 4.3.2.2.Respiratory Physiological Phenomena: Physiological processes and properties of the RESPIRATORY SYSTEM as a whole or of any of its parts.Anesthesia, Intravenous: Process of administering an anesthetic through injection directly into the bloodstream.Catecholamines: A general class of ortho-dihydroxyphenylalkylamines derived from tyrosine.Norepinephrine: Precursor of epinephrine that is secreted by the adrenal medulla and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers and of the diffuse projection system in the brain arising from the locus ceruleus. It is also found in plants and is used pharmacologically as a sympathomimetic.

Identification of cardiac beta-adrenergic receptors by (minus) [3H]alprenolol binding. (1/127)

(Minus) [3-H] alprenolol, a potent beta-adrenergic antagonist, was used to identify binding sites in a fraction of canine cyocardium. Beta adrenergic agonists and antagonists compete for these binding sites in a manner which directly parallels their known affinity for the cardiac beta-adrenergic receptor. Thus, binding was highly stereo-specific, with the (minus) isomers of beta-adrenergic agonists or antagonists being at least two orders of magnitude more potent than were the (plus) isomers in competing for these sites. The order of potency for inhibition of binding by beta-adrenergic agonists was (minus) isoproterenol greater than (minus) epinephrine greater than (minus) norepinephrine. The dissociation constant (KD) of (minus) alprenolol for the beta-adrenergic receptors was 7-11 nM as determined independently by direct binding studies or by inhibition of isoproterenol-stimulated adenylate cyclase [ATP pyrophosphate-lyase (cyclizing), EC 4.6.1.1]. The beta-adrenergic antagonist (minus) propranolol also had high affinity for the binding sites (KD equals 12 nM). The physiologically inactive catechol-containing compounds pyrocatechol and (plus or minus) dihydroxymandelic acid, as well as the metabolite (plus or minus) normetanephrine, and the alpha-adrenergic antagonist phentolamine did not compete for the binding sites at a concentration of 160 muM. Binding was rapid (t1/2 less than 30 sec) and was rapidly reversible (t1/2 less than 15 sec). The binding sites were saturable and bound 0.35 pmol of (minus) [3-H] alprenolol per mg of membrane protein. These characteristics suggest that these binding sites represent the cardiac beta-adrenergic receptors.  (+info)

Catecholamine-induced subsensitivity of adenylate cyclase associated with loss of beta-adrenergic receptor binding sites. (2/127)

Injection of frogs with beta-adrenergic catecholamines for 1-24 hr produces marked subsensitivity of the erythrocyte membrane adenylate cyclase [ATP pyrophosphate-lyase (cyclizing); EC 4.6.1.1.] to in vitro stimulation by isoproterenol. The subsensitization is specific for catecholamine stimulation, since basal and fluoride-stimulated enzyme activity are unaffected. Maximum isoproterenol-stimulated adenylate cyclase activity declines by 75% in the isoproterenol-treated animals (P less than 0.001). The concentration of isoproterenol causing one-half maximal activation of adenylate cyclase, however, is unaltered. (-)[3H]Alprenolol, a potent competitive beta-adrenergic antagonist, was used to study directly the beta-adrenergic receptor binding sites in the erythrocyte membranes from control and subsensitized animals. A highly significant (P less than 0.005) 60% fall in the number of the beta-adrenergic receptor binding sites ("specific"(-)[3H]alprenolol binding sites) in the treated animals was found. The binding affinity of the sites was not markedly altered. These data suggest that beta-adrenergic catecholamines are able to regulate catecholamine sensitivity of tissues in vivo, by regulating the properties of the beta-adrenergic receptor binding sites.  (+info)

Rapid changes in rat pineal beta-adrenergic receptor: alterations in l-(3H)alprenolol binding and adenylate cyclase. (3/127)

The properties of the beta-adrenergic receptor which regulates adenylate cyclase [ATP pyrophosphate-lyase (cyclizing)8 EC 4.6.1.1] in the pineal gland are similar to the properties of the sites which specifically bind l-[3H]alprenolol, a potent beta-adrenergic antagonist. Stimulation of the beta-adrenergic receptor results in a 30-fold increase in the activity of N-acetyltransferase (= arylamine acetyltransferase; acetyl CoA:arylamine N-acetyltransferase, EC 2.3.1.5), an enzyme involved in the synthesis of thepineal hormone melatonin. In the normal diurnal light-dark cycle there is greater physiological stimulation of the beta-adrenergic receptor in the pineal during the night than during the day. Pineals from rats kept in constant light for 24 hr possess more hormone-sensitive adenylate cyclase and specifically bind more l-[3H]alprenolol than do pineals from rats kept in the dark overnight. When rats, exposed to light for 24 hr, are treated with the beat-adrenergic agonist isoproterenol, there is a rapid loss of both hormone-sensitive adenylate cyclase activity and specific l-[3H]alprenolol binding sites. There is no change in the affinity of adenylate cyclase for isoproterenol or for its substrate, ATP. Similarly, although there are fewer binding sites, there is no change in the affinity of the remaining sites for either agonist or antagonist. Inhibition of protein synthesis with cycloheximide does not affect the loss of either adenylate cyclase activity or specific binding sites. The data suggest that stimulation of the beta-adrenergic receptor causes a rapid decrease in the number of available receptors and in hormone-sensitive adenylate cyclase activity; conversely, lack of stimulation causes an increase in these parameters. It is suggested that these changes contribute to the phenomena of super- and subsensitivity in the pineal gland by regulating the capacity of the pineal to synthesize cyclic AMP in response to beta-adrenergic stimulation.  (+info)

Involvement of beta1- and beta2- but not beta3-adrenoceptor activation in adrenergic PYY secretion from the isolated colon. (4/127)

The secretion of PYY by endocrine L cells of the terminal gut is under the control of nutrients, the autonomic nervous system and hormones. Catecholamines, and the non-specific beta-adrenergic agonist isoproterenol induce PYY secretion from rat isolated colon or ileum. Because beta3-adrenergic receptors now appear to mediate many of the effects of catecholamines in the gastrointestinal tract, we investigated the involvement of beta1-, beta2-, and beta3-adrenoceptor stimulation in PYY secretion from the isolated, vascularly perfused rat colon. Infusion of 10(-6) M isoproterenol induced a transient increase in PYY secretion (from 36+/-4 to 87+/-20 fmol/2 min; n=7, P<0.05), that was abolished by a previous infusion of the beta1- and beta2-adrenergic blocker (and partial beta3-agonist) alprenolol (10(-6) M). The beta1-adrenergic agonist dobutamine and the beta-2 agonist terbutaline also (both at 10(-5) M) significantly stimulated PYY secretion, from 29+/-1 to 79+/-12 fmol/2 min and from 19+/-1 to 73+/-13 fmol/2 min respectively (n=7, P<0.05). Neither of the beta3-adrenergic agonists tested (BRL 37 344 (10(-5), 10(-6) M) and SR 58 611A (10(-6) M)) significantly stimulated PYY secretion, thus confirming the exclusive involvement of beta1- and beta2-receptors in beta-adrenergic agonist induced hormone secretion.  (+info)

Pharmacological analysis of dopamine action on the isolated dog atrium. (5/127)

The isolated right atrium of the dog was perfused with arterial blood introduced from a carotid artery of a support dog. The selective injection of dopamine, tyramine and norepinephrine into the cannulated sinus node artery induced dose-relatedly positive chronotropic and inotropic effects. However, for an equal increase in sinus rate, dopamine caused less increase in tension development than norepinephrine. Tyramine caused least increase in contractility. Effects induced by dopamine were not blocked by treatment with tetrodotoxin which blocked those induced by nicotine. Desmethylimipramine treatment significantly suppressed dopamine-induced effects and completely blocked tyramine-induced ones but rather enhanced norepinephrine-induced ones. Alprenolol inhibited effects of dopamine, tyramine and norepinephrine. From these results, it is concluded that positive chronotropic and inotropic effects of dopamine are partly due to tyramine-like effect which causes the release of norepinephrine from sympathetic storage sites.  (+info)

Maltodextrin-based proniosomes. (6/127)

Niosomes are nonionic surfactant vesicles that have potential applications in the delivery of hydrophobic or amphiphilic drugs. Our lab developed proniosomes, a dry formulation using a sorbitol carrier coated with nonionic surfactant, which can be used to produce niosomes within minutes by the addition of hot water followed by agitation. The sorbitol carrier in the original proniosomes was soluble in the solvent used to deposit surfactant, so preparation was tedious and the dissolved sorbitol interfered with the encapsulation of one model drug. A novel method is reported here for rapid preparation of proniosomes with a wide range of surfactant loading. A slurry method has been developed to produce proniosomes using maltodextrin as the carrier. The time required to produce proniosomes by this simple method is independent of the ratio of surfactant solution to carrier material and appears to be scalable. The flexibility of the proniosome preparation method would allow for the optimization of drug encapsulation in the final formulation based on the type and amount of maltodextrin. This formulation of proniosomes is a practical and simple method of producing niosomes at the point of use for drug delivery.  (+info)

Effect of chronic beta-adrenergic receptor blockade in congestive cardiomyopathy. (7/127)

Adrenergic beta-blocking agents were given to 7 patients with advanced congestive cardiomyopathy who had tachycardia at rest (98 plus or minus 13 beats/min). The patients were on beta-adrenergic receptor blockade for 2 to 12 months (average 5-4 months). One patient was given alprenolol 50 mg twice daily and the other patients were given practolol 50 to 400 mg twice daily. Virus infection had occurred in 6 of the patients before the onset of symptoms of cardiac disease. All patients were in a steady state or were progressively deteriorating at the start of beta-adrenergic receptor blockade. Conventional treatment with digitalis and diuretics was unaltered or reduced during treatment with beta-blocking agents. An improvement was seen in their clinical condition shortly after administration of the drugs. Continued treatment resulted in an increase in physical working capacity and a reduction of heart size. Noninvasive investigations including phonocardiogram, carotid pulse curve, apex cardiogram, and echocardiogram showed improved ventricular function in all cases. The present study indicates that adrenergic beta-blocking agents can improve heart function in at lease some patients with congestive cardiomyopathy. Furthermore, it is suggested that increased catecholamine activity may be an important factor for the development of this disease, as has been shown in animal experiments.  (+info)

Identification of beta-adrenergic receptors in human lymphocytes by (-) (3H) alprenolol binding. (8/127)

Human lymphocytes are known to posessess a catecholamine-responsive adenylate cyclase which has typical beta-adrenergic specificity. To identify directly and to quantitate these beta-adenergic receptors in human lymphocytes, (-) [3H] alprenolol, a potent beta-adrenergic antagonist, was used to label binding sites in homogenates of human mononuclear leukocytes. Binding of (-) [3H] alprenolol to these sites demonstrated the kinetics, affinity, and stereospecificity expected of binding to adenylate cyclase-coupled beta-adrenergic receptors. Binding was rapid (t1/2 less than 30 s) and rapidly reversible (t1/2 less than 3 min) at 37 degrees C. Binding was a saturable process with 75 +/- 12 fmol (-) [3H] alprenolol bound/mg protein (mean +/- SEM) at saturation, corresponding to about 2,000 sites/cell. Half-maximal saturation occurred at 10 nM (-) [3H] alprenolol, which provides an estimate of the dissociation constant of (-) [3H] alprenolol for the beta-adrenergic receptor. The beta-adrenergic antagonist, (-) propranolol, potently competed for the binding sites, causing half-maximal inhibition of binding at 9 nM. beta-Adrenergic agonists also competed for the binding sites. The order of potency was (-) isoproterenol greater than (-) epinephrine greater than (-)-norepinephrine which agreed with the order of potency of these agents in stimulating leukocyte adenylate cyclase. Dissociation constants computed from binding experiments were virtually identical to those obtained from adenylate cyclase activation studies. Marked stereospecificity was observed for both binding and activation of adenylate cyclase. (-)Stereoisomers of beta-adrenergic agonists and antagonists were 9- to 300-fold more potent than their corresponding (+) stereoisomers. Structurally related compounds devoid of beta-adrenergic activity such as dopamine, dihydroxymandelic acid, normetanephrine, pyrocatechol, and phentolamine did not effectively compete for the binding sites. (-) [3H] alprenolol binding to human mononuclear leukocyte preparations was almost entirely accounted for by binding to small lymphocytes, the predominant cell type in the preparations. No binding was detectable to human erythrocytes. These results demonstrate the feasibility of using direct binding methods to study beta-adrenergic receptors in a human tissue. They also provide an experimental approach to the study of states of altered sensitivity to catecholamines at the receptor level in man.  (+info)

Seven healthy volunteers showing a fourteenfold range in steady-state plasma concentrations on oral alprenolol (200 mg b.i.d.) were investigated by administration of 5 mg of the drug intravenously and then 50, 100, 150, and 200 mg as single oral doses. The rank order for individual steady-state plasma concentrations was the same as that for the relative bioavailability of the 200 mg dose. The area under the plasma concentration-time curve showed a nonlinear increase with the dose. As the relative availability was a good predictor of steady state while clearance after intravenous administration was not, it was concluded that differences in first-pass elimination markedly contribute to the interindividual variability in steady state plasma concentrations. After pentobarbital treatment, the area under the plasma concentration curve of the 200 mg dose was decreased to 32% and 59% of the pretreatment values in two subjects, but there was no change in the plasma half-life of alprenolol. This indicates

We have demonstrated previously a postnatal peak for the beta adrenergic receptor in the heart and detected the appearance of a beta adrenergic receptor before an (-)-isoproterenol inducible increase in heart rate. The present study examined 1) agonist displaceable [3H] dihydroalprenolol (DHA) binding in the neonatal and adult mouse heart and 2) adenylate cyclase in fetal, neonatal and adult mouse heart. 3[H]DHA binding displaceable by (-)-isoproterenol gave a similar Ki from 1 day neonate through adult. Similar to the result found for antagonist displacement binding, there was a dramatic increase in the agonist displaceable [3H] DHA binding postnatally. The maximum was achieved in 2 weeks and then gradually declined to adult level. Cyclase activity (basal, (-)-isoproterenol- and NaF- stimulated) paralleled beta adrenergic receptor increases before birth. However, no early postnatal peak was present. In the 13 day fetal mouse heart, there is no (-)-isoproterenol increase in heart rate, but beta ...

We previously reported that Asn312 of the beta 2-adrenergic receptor and Asn385 in the homologous position in the 5-hydroxytryptamine1A receptor are important for binding to a class of beta-adrenergic receptor antagonists including propranolol and alprenolol. We proposed that the asparagine may be forming a hydrogen bond with the phenoxy oxygen common to these ligands. To further test this hypothesis we made alanine, threonine, phenylalanine, and glutamine substitutions at position 312 in the beta 2-adrenergic receptor. We observed that substitution with amino acids that permit formation of hydrogen bonds (threonine and glutamine) supported binding to aryloxyalkylamines, whereas substitution with amino acids that cannot form hydrogen bonds (alanine and phenylalanine) did not permit binding to these compounds. We were surprised to find that two of these substitutions led to an increase in affinity for alpha-adrenergic ligands. Substitution with glutamine and threonine at position 312 led to a ...

0214]2-adrenergic receptor numbers were measured in asthmatic mice as follows. Asthmatic mice (ovalbumin-challenged) were treated as follows: Ctrl, no drug treatment with methacholine challenge; salbutamol, a short-acting β2 agonist; carvedilol, a β1, β2 non-selective inverse agonist with α1-adrenergic antagonist activity; nadolol, a highly specific, hydrophilic β1, β2 non-selective inverse agonist; and alprenolol, a β-adrenergic antagonist. Drug treatments were either a single treatment 15 minutes prior to methacholine challenge or ongoing for 28 days (salbutamol was delivered continuously via a subcutaneous osmotic minipump and alprenolol, carvedilol, and nadolol were in animal chow). Mice were sacrificed and lung membranes were isolated as follows. Frozen lung tissue was homogenized in an ice-cold buffer containing 0.32 M sucrose and 25 mM Tris (pH 7.4) using a polytron (Pro 200, Pro Scientific, Inc.). The homogenate was centrifuged at 1000×g for 10 min at 4° C. The resulting ...
Published 8-2-1998; Reaffirmed 5-1-2006). Auditory Integration Training and Facilitated Communication for Autism. Abstract. This statement reviews the basis for two new therapies for autismauditory integration training and facilitative communication. Both therapies seek to improve communication skills. Currently available information does not support the claims of proponents that these treatments are efficacious. Their use does not appear warranted at this time, except within research protocols.. Introduction. Auditory integration training (AIT) is a treatment for autism that was originally developed by Guy Berard in France in the 1960s and introduced into the United States in 1991. It has since become increasingly popular with parents of autistic children. The publication of a book1 in 1991 that described the use of AIT in "curing" a child with autism after a 10-hour intervention program generated extensive interest, particularly among parents of autistic children who were frustrated by the ...

To more fully characterize the alterations in myocardial adrenergic and cholinergic receptors induced by the diabetic state, we investigated the binding characteristics of (-) [3H] dihydroalprenolol to beta adrenergic receptors (bAR), [3H] prazosin to alpha adrenergic receptors (aAR), and [3H] quinuclidinyl-benzilate to muscarinic cholinergic receptors (MCR) in myocardial membranes derived from rats 8 wk after treatment with streptozotocin. We also studied an equal number of animals from three control groups: free-eating nondi-abetics, pair-weighted nondiabetics, and streptozoto-cin-treated animals treated daily with insulin.. Diabetic hearts demonstrated 27% fewer bAR (P , 0.01) and 31% fewer aAR (P , 0.01) than free-eating controls, without changes in MCR, and without changes in antagonist affinity, agonist affinity, or agonist slope factor (pseudo-Hill coefficient) for any class of receptors. Food restriction had no effect on receptor characteristics, and treatment of diabetic rats with ...
Treatment of rats with chemical carcinogens, including 2-acetylaminofluorene (2-AAF), leads to a strong increase in the hepatic catecholamine-sensitive adenylate cyclase activity. The present study was undertaken to investigate the mechanism for the development of this increase. We report that hepatocytes isolated from rats which had been fed 2-AAF (0.025% w/w) for 8-12 weeks had an increased number of β-adrenoceptors, as determined by [3H]dihydroalprenolol binding to whole cells and [125I]iodocyanopindolol binding to washed particles. For both ligands the number of binding sites was about 4-fold higher in hepatocytes from 2-AAF-treated rats than in those from controls. The adenylate cyclase activity of the carcinogen-fed animals showed both a general increase manifested in the basal level (2-fold) and in the activities obtained by stimulation with guanine nucleotides (2-3-fold), cholera toxin (1.5-fold), and glucagon (1.3-fold) and a selective, larger increase in the β-adrenoceptor-linked ...
Studies conducted in our laboratory have demonstrated that activated immune cells produce a soluble inhibitor(s) of cardiac myocyte contractile and cyclic AMP (cAMP) responses to beta-adrenergic stimulation. To examine the mechanism of this effect, metabolic assays were conducted on cultured rat cardiac myocytes incubated in the presence and absence of supernatants harvested from rat activated splenocyte cultures. Intracellular cAMP accumulation in response to isoproterenol was inhibited by up to 74% in a dose-dependent fashion by conditioned media containing soluble cytokines from activated immune cells. By use of myocyte cultures in which contaminating nonmyocyte proliferation was inhibited by nonlethal irradiation, this phenomenon was shown to be independent of mitogenic effects. Isobutylmethylxanthine, a phosphodiesterase inhibitor, did not ablate cytokine-induced inhibition of cAMP accumulation. Parameters of beta-adrenergic receptor binding and affinity were also unaffected. cAMP ...
Long-term administration of imipramine caused a decrease in serotonin2 receptor binding in rat brain cerebral cortex, an effect that was abolished by ovariectomy. In contrast, ovariectomy had no effect on imipramine-induced decreases in hippocampal serotonin or in cerebral cortical and hippocampal beta-adrenergic receptor binding. Administration of estradiol or progesterone separately or in combination reestablished the effect of imipramine treatment on cortical serotonin2 receptors. These results suggest that ovarian steroids may play an important, but subtle, role in the neurochemical and perhaps clinical response to this drug. ...
The structure-activity relationships were determined for adrenergic compounds which either activated or blocked the activation of a partially purified adenyl cyclase isolated from frog erythrocytes. The results suggested that the presence of a β-hydroxyl group was essential for activity and that the potency of agonists as well as antagonists increased with the size of the substituent group of the amino nitrogen. In addition to the requirements for receptor affinity, compounds with intrinsic activity (agonists) had to have either OH or CH2OH substituents in both the m- and p-positions of the benzene ring. Since these structural requirements agreed well with those reported for intact tissue preparations, utilization of this relatively simple, cell-free preparation of adenyl cyclase may be a useful method for studying compounds with beta-adrenengic activity and for further defining the chemical nature of a beta-adrenergic receptor.. ...
The effects of dietary fats consisting of different fatty acids on lipolytic activity and body fat accumulation were studied in rats. Sprague-Dawley male rats were meal-fed an isoenergetic diet based on either beef tallow or safflower oil for 8 weeks. Lipolytic activities in epididymal and subcutaneous adipose tissues were lower in the beef tallow diet group than in the safflower oil diet group. Body fat accumulation was greater in rats fed the beef tallow diet versus the safflower oil diet. Norepinephrine (NE) turnover rates used as an index of sympathetic activities in adipose tissues were lower in the beef tallow diet group. beta-Adrenergic receptor binding was determined with [3H]dihydroalprenolol. Binding affinities of beta-receptors in adipose tissues were significantly lower in the beef tallow diet group. Membrane fluidities of adipose tissues were also lower in the beef tallow diet group. Membrane fluidities were correlated with the affinities of the beta-receptor. We believe from these ...
Chlordimeform (N(4-chloro-o-tolyl)-N, N-dimethylformamidine; CDM) is a formamidine insecticide/acaricide whose major active metabolite is its N-monomethyl analog, desmethylchlordimeform, (DCDM). While their pesticidal action in invertebrates appears to be related to activation of octopamine receptors, their mechanism of action in mammals has not been established. Because of similarities between octopamine and adrenergic receptors and suggestions of CDM and DCDM action on adrenoceptors, the in vitro interactions of CDM and DCDM with adrenoceptors were studied. In mouse brain membrane preparations CDM inhibited the binding of [3H]-clonidine to alpha2- adrenoceptors and of [3H]-WB4101 to alpha1-adrenoceptors with IC50 values of 18.2 and 87 μM, respectively. DCDM was a much more potent inhibitor, with IC50 values toward alpha2−, and alpha1-adrenoceptors of 44 nM and 1 μM, respectively. Both compounds were only weak inhibitors of the binding of [3H]-dihydroalprenolol to beta-adrenoceptors and of [3H]

Although β1-blockers have been perioperatively used to reduce the cardiac disorders associated with general anesthesia, little is known about the mechanistic characteristics of ultra-short-acting highly selective β1-blocker landiolol. We studied its membrane-interacting property in comparison with other selective and nonselective β1-blockers. Biomimetic membranes prepared with phospholipids and cholesterol of varying compositions were treated with β1-selective landiolol and esmolol and nonselective propranolol and alprenolol at 0.5-200 µM. The membrane interactivity and the antioxidant activity were determined by measuring fluorescence polarization and by peroxidizing membrane lipids with peroxynitrite, respectively. Nonselective β1-blockers, but not selective ones, intensively acted on 1,2-dipalmitoylphosphatidylcholine liposomal membranes and cardiomyocyte-mimetic membranes to increase the membrane fluidity. Landiolol and its inactive metabolite distinctively decreased the fluidity of 1,2
Observations have been made on the role of a divalent cation (calcium ion) during OsO4 fixation of nuclei of frog erythrocytes, mainly after isolation from cells. The volume of the nucleus depends partly on the molecular interaction of charged macromolecules, is controlled by the ionic strength of the medium, and hence may be used as a guide in attempts to preserve structure. When the isolation and fixation media contain 0.01 M calcium at pH 6.3 the volume changes, in the light microscope, during processing are small. When the fixative does not contain these ions, reversible volume changes occur during fixation and dehydration. The chromatin of nuclei processed with minimal volume change appears, in the electron microscope, to contain fine dots and lines about 20 to 40 A in diameter, relatively close together. The chromatin structure of nuclei in which volume changes have occurred consists of dense irregularly shaped patches, relatively far apart, and ranging in diameter from about 200 A down to ...

Adrenergic beta-blocking agents were given to 7 patients with advanced congestive cardiomyopathy who had tachycardia at rest (98 plus or minus 13 beats/min). The patients were on beta-adrenergic receptor blockade for 2 to 12 months (average 5-4 months). One patient was given alprenolol 50 mg twice daily and the other patients were given practolol 50 to 400 mg twice daily. Virus infection had occurred in 6 of the patients before the onset of symptoms of cardiac disease. All patients were in a steady state or were progressively deteriorating at the start of beta-adrenergic receptor blockade. Conventional treatment with digitalis and diuretics was unaltered or reduced during treatment with beta-blocking agents. An improvement was seen in their clinical condition shortly after administration of the drugs. Continued treatment resulted in an increase in physical working capacity and a reduction of heart size. Noninvasive investigations including phonocardiogram, carotid pulse curve, apex cardiogram, ...
