Angiotensin Amide: The octapeptide amide of bovine angiotensin II used to increase blood pressure by vasoconstriction.Angiotensin II: An octapeptide that is a potent but labile vasoconstrictor. It is produced from angiotensin I after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME. The amino acid in position 5 varies in different species. To block VASOCONSTRICTION and HYPERTENSION effect of angiotensin II, patients are often treated with ACE INHIBITORS or with ANGIOTENSIN II TYPE 1 RECEPTOR BLOCKERS.Amides: Organic compounds containing the -CO-NH2 radical. Amides are derived from acids by replacement of -OH by -NH2 or from ammonia by the replacement of H by an acyl group. (From Grant & Hackh's Chemical Dictionary, 5th ed)Receptor, Angiotensin, Type 1: An angiotensin receptor subtype that is expressed at high levels in a variety of adult tissues including the CARDIOVASCULAR SYSTEM, the KIDNEY, the ENDOCRINE SYSTEM and the NERVOUS SYSTEM. Activation of the type 1 angiotensin receptor causes VASOCONSTRICTION and sodium retention.Receptors, Angiotensin: Cell surface proteins that bind ANGIOTENSINS and trigger intracellular changes influencing the behavior of cells.Receptor, Angiotensin, Type 2: An angiotensin receptor subtype that is expressed at high levels in fetal tissues. Many effects of the angiotensin type 2 receptor such as VASODILATION and sodium loss are the opposite of that of the ANGIOTENSIN TYPE 1 RECEPTOR.Angiotensin I: A decapeptide that is cleaved from precursor angiotensinogen by RENIN. Angiotensin I has limited biological activity. It is converted to angiotensin II, a potent vasoconstrictor, after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME.Angiotensin Receptor Antagonists: Agents that antagonize ANGIOTENSIN RECEPTORS. Many drugs in this class specifically target the ANGIOTENSIN TYPE 1 RECEPTOR.Angiotensin II Type 1 Receptor Blockers: Agents that antagonize ANGIOTENSIN II TYPE 1 RECEPTOR. Included are ANGIOTENSIN II analogs such as SARALASIN and biphenylimidazoles such as LOSARTAN. Some are used as ANTIHYPERTENSIVE AGENTS.Angiotensin III: A heptapeptide formed from ANGIOTENSIN II after the removal of an amino acid at the N-terminal by AMINOPEPTIDASE A. Angiotensin III has the same efficacy as ANGIOTENSIN II in promoting ALDOSTERONE secretion and modifying renal blood flow, but less vasopressor activity (about 40%).Losartan: An antagonist of ANGIOTENSIN TYPE 1 RECEPTOR with antihypertensive activity due to the reduced pressor effect of ANGIOTENSIN II.Tetrazoles

Immunologic production of antiangiotensin. I. Preparation of angiotensin-protein complex antigen. (1/13)

Angiotensin II was coupled with bovine gamma-globulin (BGG) through the following series of reactions. See PDF for Structure By determinations of the aromatic amine and tyrosine contents of p-aminobenzoylangiotensin II, the number of p-aminobenzoyl residues introduced per molecule of angiotensin II was calculated. Absorption spectra (between 250 and 500 mmicro) of BGG complexes of p-aminobenzoylangiotensin II and six different para substituted aromatic amines were compared. Specific activities (dog units/millimicromole) of the different intermediate products were determined. Presence of a terminal, free amino group does not appear to be an absolute requirement for the biological activity of angiotensin II, since substitution of a p-aminobenzoyl radical in this group yields a product with 40 to 50 per cent of the activity of the parent compound. Angiotensin I, on the other hand, is completely inactivated under identical circumstances. Possible implication of this finding has been discussed.  (+info)

Immunologic production of antiangiotensin. II. Production and detection of antiangiotensin. (2/13)

The parenteral administration of benzoylangiotensin II-azo-BGG to rabbits produced an antiserum with antiangiotensin activity. Antiangiotensin inhibited the biological action of p-aminobenzoylangiotensin II, valine(5)-angiotensin II (free acid form), isoleucine(5)-angiotensin II and valine(5)-angiotensin II (amide form), but it was totally inert towards angiotensin 1. Antiangiotensin activity was distinguished from that of serum angiotensinase by the following observations: (a) an angiotensinase-free gamma-globulin fraction contained antiangiotensin, (b) angiotensinase inactivated angiotensin II (both the amide and free acid forms) and angiotensin I in contrast to the remarkable specificity for angiotensin II exhibited by antiangiotensin. Serological demonstration of antiangiotensin included: (a) a comparison of its precipitin reaction with the angiotensin BGG complex with the reaction with BGG alone, (b) the partial inhibition of the precipitin reaction with the angiotensin BGG complex by angiotensin II, (c) a precipitin reaction with a different angiotensin II protein complex (cat serum). Angiotensin II administered parenterally as the free polypeptide was not antigenic.  (+info)

Some pharmacological actions of synthetic analogues of angiotensinamide. (3/13)

In order to evaluate the importance of some structural features of asparagyl(1)-Valyl(5)-angiotensin II (angiotensinamide) for its pharmacological actions, the relative potencies of angiotensinamide and five peptide analogues were studied on the blood pressure of the rat, the isolated rat uterus and the isolated guinea-pig ileum. All the modifications of the angiotensinamide structure that were studied led to a decrease of potency which, however, was not the same on all three preparations. The importance of the guanido group, the phenolic group and the length of the peptide chain for the pharmacological activities of these peptides is discussed.  (+info)

Actions of some peptides on bronchial muscle. (4/13)

The decapeptide kallidin-10, substance P and angiotensin increased the resistance of guinea-pig lungs to inflation; lysine- or arginine-vasopressin and oxytocin were inactive. Acetylsalicylate antagonized this action of kallidin-10, as it does that of bradykinin, but it failed to antagonize substance P or angiotensin. Bradykinin also increased resistance to inflation of rabbit lungs and, to a lesser extent, rat lungs. It caused a relatively slow contraction of guinea-pig tracheal and bronchial muscle in vitro, but it did not contract isolated rabbit, dog or human bronchus. The relative potencies of different substances on different bronchial test preparations, and also in different species, were not parallel.  (+info)

Pharmacological actions of pepsitensin. (5/13)

In confirmation of the results of Croxatto and his co-workers, plasma proteins incubated with pepsin yielded a substance (pepsitensin) with pressor activity. Euglobulin gave a much higher yield than the other plasma protein fractions. Incubation for 4 hr at pH 4 gave high yields of pressor activity (pepsitensin) but no antidiuretic activity; incubation of euglobulin for 4 hr at pH 2.5 yielded extracts with antidiuretic as well as pressor activity. Incubation for 8 to 11 hr at pH 2.5 produced the highest yield of both activities. Further incubation, at the same pH, up to 20 hr caused a rapid decline in the pressor activity of the extracts, but the antidiuretic activity was much more resistant to destruction by pepsin. Pepsitensin was found to be very soluble in water and poorly soluble in organic solvents. It is not inactivated by thioglycollate. In blood pressure assays some animals did not respond to pepsitensin, and nephrectomized (17 to 24 hr) rats were found to be more suitable preparations. Pepsitensin was shown to exert pressor effect by direct action on the blood vessels. Its pressor action could be differentiated from that of tyramine, dimethylphenylpiperazine, nicotine, noradrenaline and Pitressin but not from that of angiotensin. The isolated guinea-pig ileum and the rat uterus were equally sensitive to angiotensin and pepsitensin. In paper chromatograms, in the solvent system butanol-acetic acid-water, the R(F) of pepsitensin was very similar to that of angiotensin.  (+info)

Stimulation of intestinal nervous elements by angiotensin. (6/13)

The stimulation of nervous elements in the intestine by the polypeptide angiotensin has been examined. Comparisons between nicotine, a neurotropic agent, acetylcholine which exerts principally a musculotropic action and angiotensin have been made by examining their interactions with hexamethonium and the anticholinesterase 1,5-di-(p-N-allyl-N-methylaminophenyl)pentan-3-one dibromide in both the rabbit and guinea-pig ileum. The effect of atropine on the responses of the guinea-pig ileum and botulinum toxin on the responses of the rabbit ileum to angiotensin was also tested. The results show that angiotensin causes most of its contractile response in both the guinea-pig and rabbit ileum by an indirect action, through the stimulation of nervous tissue.  (+info)

Home blood pressure monitoring in diabetes. (7/13)

Forty three children with diabetes were recruited to evaluate home blood pressure monitoring using an electronic oscillometric sphygmomanometer (Philips HP5330). This device was found to be simple to use and reliable. It fulfilled the accuracy criteria of the American Association for the Advancement of Medical Instrumentation for both systolic and diastolic blood pressure and those of the British Hypertension Society for systolic blood pressure. Thirty eight children successfully measured their own blood pressure at home and taught other family members to do the same. The results indicate that home blood pressure monitoring is of value in the management of diabetic children.  (+info)

The stainability of neural elements is determined during the various stages of tissue preparation which precede impregnation.. The hypothesis (Romanes, 1950) that variations in the physiological state of the neurones at the time of fixation might influence the stain was examined. Feeding and anaesthesia did not influence the staining of gastric nerve fibres under the conditions of the experiments.. A study was made of fixing fluids for Bodian staining. A picric-acetic-alcohol mixture and alcoholic Bouin were convenient and effective, each being superior to formaldehyde-acetic-alcohol. For overnight fixation formaldehyde solution neutralized with calcium carbonate was satisfactory, but where prolonged fixation is permissible formaldehyde neutralized with excess of magnesium carbonate gave superior results.. Attention was drawn to the probability that the final stain could be improved by pretreatment of mounted sections before silvering. Dewaxed sections were treated individually with 27 ...

The examination of synthetic valyl-5-angiotensin II-amide in the conscious dog revealed the following:. 1. Both the arterial and the central venous pressure responses exhibit tachyplylaxis when high doses of angiotensin II are administered, althoug not when medium or low doses are given. Cross-tachyphylaxis can be demonstrated between renin and angiotensin II but not between either of these and norepinephrine. These results suggest that tachyphylaxis to renin is due to tachyphylaxis to angiotensin.. 2. Angiotensin II and norepinephrine provoke a dose-dependent increase in central venous pressure. The threshold dose is about 10 times higher than that necessary for the effect on arterial pressure. In doses eliciting the same increase of arterial blood pressure, norepinephrine is about twice as active on the venous pressure as angiotensin II.. 3. Anesthesia and atropinization both reduce or abolish the effect of angiotensin II as well as that of norepinephrine on the venous pressure, indicating the ...

β-Methylphenethylamine (β-Me-PEA, BMPEA), or 1-amino-2-phenylpropane, is an organic compound of the phenethylamine class, and a positional isomer of the drug amphetamine, with which it shares some properties. In particular, both amphetamine and β-methylphenethylamine are human TAAR1 agonists. In appearance, it is a colorless or yellowish liquid. Relatively little information has been published about this substance. Hartung and Munch reported that it had good antihypotensive (pressor) activity in experimental animals, and that it was orally active. The MLD (minimum lethal dose) for the HCl salt was given as 500 mg/kg (rat, s.c.) and 50 mg/kg (rabbit, i.v.). A study by Graham and co-workers at the Upjohn Co., comparing a large number of β-methylphenethylamines substituted on the benzene ring showed that β-methylphenethylamine itself had 1/700 x the pressor activity of epinephrine, corresponding to ~ 1/3 the potency of amphetamine. The β-methyl compound also had ~ 2 x the broncho-dilating ...

London, Sep 14 (IANS) Researchers have extracted an active pharmaceutical substance from the leaves of a common ornamental plant - coralberry - which could provide hope for people with asthma. The findings, led by researchers at the University of Bonn in Germany and asthma specialists from the UK, showed that the leaves of the coralberry contain a substance with the cryptic name "FR900359".. The extracts when used in mice almost inhibited the characteristic contraction of the airways. Further, the study found that "FR900359" is very effective at preventing the bronchial muscles from contracting. Asthmatics regularly suffer from these pronounced contractions preventing adequate ventilation of the lungs. The resulting shortness of breath can be life-threatening.. The compound in the coralberry leaves relieves these spasms and is supposedly more effective and has a more prolonged action than the most common asthma drug salbutamol, the researchers noted in the paper published in the journal Science ...

In a previous study, we demonstrated that administration of CGRP can reverse the hypertension induced by L-NAME during pregnancy but not during the postpartum period. The results of the present study provide evidence that endogenous CGRP is also playing a hemodynamic role in this model of experimental preeclampsia. The CGRP8-37-induced increase of the already elevated MAP in the L-NAME-treated rats on days 19 to 21 of pregnancy indicates that in this setting, CGRP is acting as a compensatory vasodilator in an attempt to buffer the elevated BP. Interestingly, the pressor effect of the CGRP antagonist was attenuated on postpartum day 1, which is consistent with what we observed in our earlier studies using exogenously administered CGRP.. In light of the rapid onset of the hypertensive effect of CGRP8-37 in the L-NAME-treated pregnant rats, and because the antagonist probably does not penetrate the central nervous system, it is likely that the pressor activity of CGRP8-37 seen in these experiments ...

1. Competitive or non-competitive inhibition of the myotropic and pressor response of angiotensin II is dependent on the nature of the substituent in position 8 of the antagonist peptide analogue. Substituents in other positions of the molecule, particularly position 1, contribute greatly to the potency of these antagonists.. 2. As is evidenced after adrenalectomy or after blockade with phentolamine and phenoxybenzamine, the initial pressor activity observed with all the antagonistic peptides is partially due to the release of catecholamines and partially to a direct myotropic effect.. 3. [Sar1, Thr8]angiotensin II has been found to possess the lowest agonist to antagonist ratio of all antagonists tested.. 4. [Des-Asp1, Ile8]angiotensin II selectively and specifically inhibits the release of aldosterone from adrenal cortex. Thus, unlike angiotensin II, this heptapeptide has pronounced organ specificity, suggesting that the heptapeptide (angiotensin III) is the aldosterone-releasing ...

Participants will be followed for 60 days. ...
We endeavour to identify the structural determinants of peptide analogues and their cognate GPCRs involved in LiSS which will assist in the development of signal-selective ligands/drugs, directed at different clinical endpoints with improved therapeutic outcomes and reduced side-effects. When activated, GPCRs can also interact with different G proteins or other GPCR-interacting proteins (GIPs) at the intracellular side to mediate different pharmacological actions. We have shown that binding of different peptides to the same receptor can stabilise different receptor shapes that preferentially activate different pharmacological actions which we termed "ligand-induced selective signalling". G protein-coupled receptors (GPCRs) constitute the largest superfamily of cell surface signalling proteins which are characterised by the architecture of 7-transmembrane domains. GPCRs play a pivotal role in mediating signal transduction of endogenous ligands, such as neurotransmitters and hormones, from the ...

The world stands on the edge of an historic public health success with the imminent eradication of dracunculiasis (guinea-worm disease) and polio. Since the World Health Assembly called for the eradication of dracunculiasis in 1986 and poliomyelitis in 1988, astonishing progress has been made. In 2016, only 25 human cases of dracunculiasis were reported from three countries, transmission of wild poliovirus was found in only three countries, and 37 cases of polio were reported worldwide. In addition to these achievements, there has been progress in the elimination of the little-known disease podoconiosis (endemic non-filarial elephantiasis). Essential to Alu-equivalent family elimination effort is the need to understand the geography of the disease to identify potentially at-risk areas and set a benchmark for evaluating elimination efforts. The global burden of podoconiosis is not at present clearly defined, although available estimates suggest that globally there are 4 million people with ...
