Effects of monosodium glutamate-induced obesity in spontaneously hypertensive rats vs. Wistar Kyoto rats: serum leptin and blood flow to brown adipose tissue. (1/90)

We compared the effects of hypothalamic obesity induced by neonatal monosodium glutamate (MSG) treatment between spontaneously hypertensive rats (SHR) and normotensive Wistar Kyoto rats (WKY). Newborn WKY and SHR were injected intraperitoneally with 4 mg/kg body weight of MSG daily for 5 days. At 6 months of age, the obesity of SHR was more advanced than that of WKY, but at 14 months of age the severity of obesity was similar between the two strains. Hypertriglyceridemia was enhanced in MSG-treated SHR as compared with MSG-treated WKY. Systolic blood pressure measured by the tail-cuff method was consistently lower in MSG-treated SHR than in control SHR, whereas blood pressure was not affected by neonatal MSG treatment in WKY. Food restriction reduced body weight more in control SHR than in control WKY, with the former also showing enhanced ketogenesis. Neonatal MSG treatment abolished the accelerated reduction of body weight in SHR. Serum leptin concentration was markedly increased in MSG-treated obese rats, though no differences were seen between WKY and SHR in the control or MSG-treated groups. Serum leptin was closely correlated with both Lee obese index and mesenteric fat weight over the strain. Blood flow in interscapular brown adipose tissue (BAT) measured by Laser Doppler flowmetry was significantly increased in response to beta3-adrenoceptor agonist BRL26830A in both the control and MSG-treated rats. However, the response of blood flow was not affected by MSG treatment or strain difference. The present study demonstrated some strain differences in response to neonatal MSG treatment between WKY and SHR. These differences could not be explained by the difference in serum leptin level or beta3-adrenergic reactivity in BAT.  (+info)

CCAAT/enhancer-binding protein alpha is required for transcription of the beta 3-adrenergic receptor gene during adipogenesis. (2/90)

The beta(3)-adrenergic receptor (beta(3)AR) is expressed predominantly in adipocytes, and it plays a major role in regulating lipolysis and adaptive thermogenesis. Its expression in a variety of adipocyte cell models is preceded by the appearance of CCAAT/enhancer-binding protein alpha (C/EBP alpha), which has been shown to regulate a number of other adipocyte-specific genes. Importantly, it has been demonstrated that several adipocyte cell lines that fail to express C/EBP alpha exhibit reduced insulin sensitivity, despite an apparent adipogenic phenotype. Here we show that transcription and function of the beta(3)AR correlates with C/EBP alpha expression in these adipocyte models. A 5.13-kilobase pair fragment of the mouse beta(3)AR promoter was isolated and sequenced. This fragment conferred a 50-fold increase in luciferase reporter gene expression in adipocytes. Two putative C/EBP binding sites exist at -3306 to -3298 and at -1462 to -1454, but only the more distal site is functional. Oligonucleotides corresponding to both the wild-type and mutated -3306 element were inserted upstream of a thymidine kinase luciferase construct. When cotransfected in fibroblasts with a C/EBP alpha expression vector, reporter gene expression increased 3-fold only in the wild-type constructs. The same mutation, when placed into the intact 5.13-kilobase pair promoter, reduced promoter activity in adipocytes from 50-fold to <10-fold. Electrophoretic mobility shift analysis demonstrated that the site at -3306 generated a specific protein-oligonucleotide complex that was supershifted by C/EBP alpha antibody, while a probe corresponding to a putative site at -1462 did not. These results define C/EBP alpha as a key transcriptional regulator of the mouse beta(3)AR gene during adipogenesis.  (+info)

(+/-)-Pindolol acts as a partial agonist at atypical beta-adrenoceptors in the guinea pig duodenum. (3/90)

The agonistic and antagonistic effects of (+/-)-pindolol (1-(1H-indol-4-yloxy)-3-[(1-methylethyl)amino]-2-propanol) were estimated to clarify whether (+/-)-pindolol acts as a partial agonist on atypical beta-adrenoceptors in the guinea pig duodenum. (+/-)-Pindolol induced concentration-dependent relaxation with a pD2 value of 5.10 +/- 0.03 and an intrinsic activity of 0.83 +/- 0.03. However, the relaxations to (+/-)-pindolol were not antagonized by the non-selective beta1- and beta2-adrenoceptor antagonist (+/-)-propranolol (1 microM). In the presence of (+/-)-propranolol (1 microM), the non-selective beta1-, beta2- and beta3-adrenoceptor antagonist (+/-)-bupranolol (30 microM) induced a rightward shift of the concentration-response curves for (+/-)-pindolol (apparent pA2 = 5.41 +/- 0.06). In the presence of (+/-)-propranolol, (+/-)-pindolol (10 microM) weakly but significantly antagonized the relaxant effects to catecholamines ((-)-isoprenaline, (-)-noradrenaline and (-)-adrenaline), a selective beta3-adrenoceptor agonist BRL37344 ((R*,R*)-(+/-)-4-[2-[(2-(3-chlorophenyl)-2-hydroxyethyl) amino]propyl]phenoxyacetic acid sodium salt) and a non-conventional partial beta3-adrenoceptor agonist (+/-)-CGP12177A([4-[3-[(1,1-dimethylethyl)amino]-2-hydroxypropoxy]-1,3-dihydro-2H -benzimidazol-2-one] hydrochloride). These results demonstrate that (+/-)-pindolol possesses both agonistic and antagonistic effects on atypical beta-adrenoceptors in the guinea pig duodenum.  (+info)

Beta(3)-adrenoceptor agonist-induced increases in lipolysis, metabolic rate, facial flushing, and reflex tachycardia in anesthetized rhesus monkeys. (4/90)

The effects of two beta(3)-adrenergic receptor agonists, (R)-4-[4-(3-cyclopentylpropyl)-4,5-dihydro-5-oxo-1H-tetrazol-1-yl]-N-[4-[2-[[2-hy droxy-2-(3-pyridinyl)ethyl]amino]ethyl]phenyl]benzenesulfonamide and (R)-N-[4-[2-[[2-hydroxy-2-(3-pyridinyl)- ethyl]amino]ethyl]phenyl]-1-(4-octylthiazol-2-yl)-5-indolinesulfonamide, on indices of metabolic and cardiovascular function were studied in anesthetized rhesus monkeys. Both compounds are potent and specific agonists at human and rhesus beta(3)-adrenergic receptors. Intravenous administration of either compound produced dose-dependent lipolysis, increase in metabolic rate, peripheral vasodilatation, and tachycardia with no effects on mean arterial pressure. The increase in heart rate in response to either compound was biphasic with an initial rapid component coincident with the evoked peripheral vasodilatation and a second more slowly developing phase contemporaneous with the evoked increase in metabolic rate. Because both compounds exhibited weak binding to and activation of rhesus beta(1)-adrenergic receptors in vitro, it was hypothesized that the increase in heart rate may be reflexogenic in origin and proximally mediated via release of endogenous norepinephrine acting at cardiac beta(1)-adrenergic receptors. This hypothesis was confirmed by determining that beta(3)-adrenergic receptor agonist-evoked tachycardia was attenuated in the presence of propranolol and in ganglion-blocked animals, under which conditions there was no reduction in the evoked vasodilatation, lipolysis, or increase in metabolic rate. It is not certain whether the beta(3)-adrenergic receptor-evoked vasodilatation is a direct effect of compounds at beta(3)-adrenergic receptors in the peripheral vasculature or is secondary to the release or generation of an endogenous vasodilator. Peripheral vasodilatation in response to beta(3)-adrenergic receptor agonist administration was not attenuated in animals administered mepyramine, indomethacin, or calcitonin gene-related peptide(8-37). These findings are consistent with a direct vasodilator effect of beta(3)-adrenergic receptor agonists.  (+info)

Upregulation of beta(3)-adrenoceptors and altered contractile response to inotropic amines in human failing myocardium. (5/90)

BACKGROUND: Contrary to beta(1)- and beta(2)-adrenoceptors, beta(3)-adrenoceptors mediate a negative inotropic effect in human ventricular muscle. To assess their functional role in heart failure, our purpose was to compare the expression and contractile effect of beta(3)-adrenoceptors in nonfailing and failing human hearts. METHODS AND RESULTS: We analyzed left ventricular samples from 29 failing (16 ischemic and 13 dilated cardiomyopathic) hearts (ejection fraction 18.6+/-2%) and 25 nonfailing (including 12 innervated) explanted hearts (ejection fraction 64.2+/-3%). beta(3)-Adrenoceptor proteins were identified by immunohistochemistry in ventricular cardiomyocytes from nonfailing and failing hearts. Contrary to beta(1)-adrenoceptor mRNA, Western blot analysis of beta(3)-adrenoceptor proteins showed a 2- to 3-fold increase in failing compared with nonfailing hearts. A similar increase was observed for Galpha(i-2) proteins that couple beta(3)-adrenoceptors to their negative inotropic effect. Contractile tension was measured in electrically stimulated myocardial samples ex vivo. In failing hearts, the positive inotropic effect of the nonspecific amine isoprenaline was reduced by 75% compared with that observed in nonfailing hearts. By contrast, the negative inotropic effect of beta(3)-preferential agonists was only mildly reduced. CONCLUSIONS: Opposite changes occur in beta(1)- and beta(3)-adrenoceptor abundance in the failing left ventricle, with an imbalance between their inotropic influences that may underlie the functional degradation of the human failing heart.  (+info)

Beta 3-adrenergic agonist up-regulates uncoupling proteins 2 and 3 in skeletal muscle of the mouse. (6/90)

Chronic stimulation of the beta3-adrenergic receptor (AR) in obese animals resulted in a reduced adiposity associated with an increased expression of thermogenic uncoupling protein (UCP)1 in adipose tissues. In this study, the mRNA expression of newly cloned UCP isoforms (UCP2 and UCP3) were examined in obese yellow KK and C57BL control mice. UCP2 mRNA was found in all tissues examined, with higher levels in adipose tissues and skeletal muscle of the obese mice. UCP3 mRNA was expressed in skeletal muscle, heart and brown adipose tissue similarly in the two mouse strains. Daily injection of a selective beta3-adrenergic agonist, CL316,243 (0.1 mg/kg), for 10 days resulted in a marked reduction of white fat pad weight and 1.8-4.8-fold increase in the mRNA levels of UCP2 and UCP3 in skeletal muscle of obese mice. No noticeable change in the UCP2 and 3 mRNA levels was found in brown and white adipose tissues. It was also found that CL316,243 injection produced a marked and sustained elevation of the plasma free fatty acid level. These results, together with our previous findings of the fatty acid-induced UCP expression in a myocyte cell line in vitro, suggest that the beta3-AR agonist-induced UCP expression in skeletal muscle may be mediated through the elevated plasma free fatty acids. It was also suggested that anti-obesity effect of beta3-AR agonists is attributable to increased thermogenesis not only by UCP1 but also by UCP2 and UCP3.  (+info)

beta-Adrenergic activation of p38 MAP kinase in adipocytes: cAMP induction of the uncoupling protein 1 (UCP1) gene requires p38 MAP kinase. (7/90)

Because of increasing evidence that G protein-coupled receptors activate multiple signaling pathways, it becomes important to determine the coordination of these pathways and their physiological significance. Here we show that the beta(3)-adrenergic receptor (beta(3)AR) stimulates p38 mitogen-activated protein kinase (p38 MAPK) via PKA in adipocytes and that cAMP-dependent transcription of the mitochondrial uncoupling protein 1 (UCP1) promoter by beta(3)AR requires p38 MAPK. The selective beta(3)AR agonist CL316,243 (CL) stimulates phosphorylation of MAP kinase kinase 3/6 and p38 MAPK in a time- and dose-dependent manner in both white and brown adipocytes. Isoproterenol and forskolin mimicked the effect of CL on p38 MAPK. In all cases activation was blocked by the specific p38 MAPK inhibitor SB202190 (SB; 1-10 microm). The involvement of PKA in beta(3)AR-dependent p38 MAPK activation was confirmed by the ability of the PKA inhibitors H89 (20 microm) and (R(p))-cAMP-S (1 mm) to block phosphorylation of p38 MAPK. Treatment of primary brown adipocytes with CL or forskolin induced the expression of UCP1 mRNA levels (6.8- +/- 0.8-fold), and this response was eliminated by PKA inhibitors and SB202190. A similar stimulation of a 3.7-kilobase UCP1 promoter by CL and forskolin was also completely inhibited by PKA inhibitors and SB202190, indicating that these effects on UCP1 expression are transcriptional. Moreover, the PKA-dependent transactivation of the UCP1 promoter, as well as its sensitivity to SB202190, was fully reproduced by a 220-nucleotide enhancer element from the UCP1 gene. We similarly observed that increased phosphorylation of ATF-2 by CL was sensitive to both H89 and SB202190, while phosphorylation of cAMP-response element-binding protein was inhibited only by H89. Together, these studies illustrate that p38 MAPK is an important downstream target of the beta-adrenergic/cAMP/PKA signaling pathway in adipocytes, and one of the functional consequences of this cascade is stimulation of UCP1 gene expression in brown adipocytes.  (+info)

Dual action of octopamine on glucose transport into adipocytes: inhibition via beta3-adrenoceptor activation and stimulation via oxidation by amine oxidases. (8/90)

Octopamine, which is closely related to norepinephrine, acts as a neurotransmitter in invertebrates and is a trace amine with undefined properties in vertebrates. The octopaminergic receptors identified in insects are targets of various pesticides but are absent in vertebrates. We have established that octopamine stimulates fat cell lipolysis in mammals via activation of beta3-adrenoceptors (ARs), whereas this amine has been described elsewhere as an alpha2-AR agonist and as a substrate for monoamine oxidase (MAO) or semicarbazide-sensitive amine oxidase (SSAO). Because we have recently reported that amine oxidase substrates promote glucose transport in rat and human adipocytes, the in vitro octopamine effects on lipolysis and glucose uptake were reassessed by using adipocytes from beta3-AR-deficient mice. The lipolytic effect and the counter-regulation of insulin action on glucose transport provoked by 0.1 to 1 mM octopamine or by 1 microM beta3-AR agonists found in control animals disappeared in adipocytes from beta3-AR-deficient mice. This revealed an insulin-like effect of octopamine on glucose uptake, which was dependent on its oxidation by MAO or SSAO, as was the case for tyramine and benzylamine, devoid of beta3-adrenergic agonism. Similarly, octopamine promoted glucose transport in human adipocytes and exhibited a weaker lipolytic stimulation than in rodent adipocytes. These findings indicate that, besides its lipolytic activity, octopamine exerts, at millimolar dose, dual effect on glucose transport in adipocytes: counteracting insulin action via beta3-AR activation and stimulating basal transport via its oxidation by MAO or SSAO.  (+info)

Phospholipids and lipid second messengers mediate mitogenic signal transduction and oncogenesis, but there have been few successful examples of small molecules that affect biologically important phospholipid metabolism. Here we investigated the actions of a previously described antitumor agent, 4-(benzyl-(2-[(2,5-diphenyloxazole-4-carbonyl)amino]ethyl)carbamoyl) -2-decanoylaminobutyric acid (SC-ααδ9), which has antisignaling properties, on phospholipases. Although SC-ααδ9 had been shown to be a potent and selective inhibitor of the Cdc25 family of dual-specificity phosphatases, many of its cellular effects are not readily reconciled with phosphatase inhibition. Molecular modeling studies suggested that SC-ααδ9 shared several structural features with membrane phospholipids. Enzyme inhibition studies in vitro revealed that SC-ααδ9 was a potent inhibitor of phospholipase C (PLC; IC50 = 25 μM) but did not inhibit phospholipase D activity at concentrations up to 100 μM.

MN-221 is a novel, highly selective ß2-adrenergic receptor agonist being developed for the treatment of exacerbations of asthma/COPD. We licensed MN-221 from Kissei Pharmaceutical Co., Ltd. Preclinical studies conducted in vitro and in vivo showed MN-221 to be highly selective for the ß2-adrenergic receptor. In these studies, the ß1-adrenergic receptor stimulating activity of MN-221 was less than that of other ß2-adrenergic receptor agonists in isolated rat atrium and in vivo cardiac function tests in rats, dogs and sheep, thereby suggesting that MN-221 may stimulate the heart less than older, less selective ß2-adrenergic receptor agonists. In addition, in vitro studies also suggested that MN-221 may act as only a partial ß1-adrenergic receptor agonist in cardiac tissue, while acting as a full ß2-adrenergic receptor in lung tissue. We believe that this improved receptor binding and functional selectivity may result in fewer cardiovascular side effects than are commonly observed with other ...

Bladder relaxation - Prostate Cancer | Medscape. Flotrol promotes bladder contol for overactive bladders. Dont let your bladder dictate your schedule - take control with the Flotrol Natural Bladder Support supplement.
Antimuscarinic drugs form the mainstay of medical treatment for Overactive bladder Syndrome (OAB). With a proven efficacy but poor tolerability, other treatment modalities have been sought. Recent concerns regarding cumulative anticholinergic load and risk of dementia have provided further impetus to find novel OAB treatments. β3-adrenoceptor (β3-AR) agonists improve OAB symptoms by relaxing bladder tissue. As such, the search is underway to develop β3-AR agonist drugs for the treatment of OAB. Areas covered: The authors discuss studies on the only approved β3-AR agonist, mirabegron, followed by reports on β3-AR agonists in development, namely ritobegron and solabegron ...

This in vitro study was performed to assess the corneal damage potential by means of the BCOP assay using fresh bovine corneae. After a first opacity measurement of the fresh bovine corneae (t0), the 20% (w/v) suspension in saline of the test item , the positive, and the negative controls were applied to corneae and incubated for 240 minutes at 32± 1 °C. After the incubation phase the test item, the positive, and the negative controls were each rinsed from the corneae andopacity was measured again (t240). After the opacity measurements permeability of the corneae was determined by measuring spectrophotometrically the transfer of sodium fluorescein after incubation in a horizontal position for 90 minutes at 32 ± 1 °C. With the negative control (saline) neither an increase of opacity nor permeability of the corneae could be observed (mean IVIS = 0.75). The positive control (10% (w/v) Benzalkonium chloride in saline) showed clear opacity and distinctive permeability of the corneae (mean IVIS = ...

TY - JOUR. T1 - α-Adrenergic receptor agonists, but not antagonists, alter the tail-flick latency when microinjected into the rostral ventromedial medulla of the lightly anesthetized rat. AU - Haws, C. M.. AU - Heinricher, Mary. AU - Fields, H. L.. PY - 1990/11/19. Y1 - 1990/11/19. N2 - The present experiments, part of an ongoing study designed to characterise the role norepinephrine (NE) in regulating the activity of putative nociceptive modulatory neurons in the rostral ventromedial medulla (RVM), assessed the effects of α-adrenergic receptor-selective agents on the nociceptive threshold (as measured by the tail-flick withdrawal response on noxious heat). These microinjection studies were carried out in the barbiturate-anesthetized rat, a preparation which is favourable for acute neurophysiological studies. The data obtained demonstrate that, as observed by others in the awake animal, activation of α2-adrenergic receptors in the RVM produces hypoalgesia. However, unlike in the awake animal, ...

Quinoline derivatives have diverse biological activities including anticancer activity. On the other hand, many sulfonamide derivatives exhibited good cytotoxic activity. Hybrids of both moieties may present novel anticancer agents. Chloroquinoline incorporating a biologically active benzene-sulfonamide moieties 5-21 and diarylsulfone derivatives 22 and 23 were prepared using (E)-1-(4-((E)-7-chloro-1-methylquinolin-4(1H)-ylideneamino)phenyl)-3-(dimethyl-amino)prop-2-en-1-one 4 as strategic starting material. The structure of the newly synthesized compounds were confirmed by elemental analyses and spectral data. Compound 4 was confirmed by X-ray crystallographic analysis. The prepared compounds were evaluated for their anticancer activity against Lung, HeLa, Colorectal and breast cancer cell lines. Compounds 2, 4, 7, 11, 14 and 17 showed better or comparable activity to 2′, 7′-dichlorofluorescein (DCF) as reference drug. Molecular docking of the active compounds on the active site of PI3K enzyme was
