Benzodiazepine analogues L365,260 and L364,718 as gastrin and pancreatic CCK receptor antagonists.
|
154 |
2473653
|
We examined the ability of the recently described 3-(benzoylamino)benzodiazepine analogue L365,260 and the 3-(acylamino)benzodiazepine analogue L364,718 to distinguish gastrin from pancreatic cholecystokinin (CCK) receptors.
|
155 |
2473653
|
Each analogue inhibited CCK-stimulated amylase release, gastrin-17-I-stimulated smooth muscle contraction, binding of 125I-Bolton-Hunter-cholecystokinin octapeptide (125I-BH-CCK-8) to pancreatic CCK receptors, and binding of 125I-gastrin-17-I to gastrin receptors on pancreatic acini.
|
156 |
2473653
|
L365,260 and L364,718 did not inhibit binding of radiolabeled vasoactive intestinal peptide, secretin, bombesin, substance P, or N-methylscopolamine to pancreatic acini.
|
157 |
2473653
|
These results demonstrate that, in contrast to other gastrin-CCK receptor antagonists described, L365,260 is a selective gastrin receptor antagonist having an 80-fold higher affinity for gastrin than pancreatic CCK receptor, whereas L364,718 has a 125-fold higher affinity for pancreatic CCK receptors.
|
158 |

This study examined the expression of the sensory neuropeptides, calcitonin gene-related peptide (CGRP) and substance P (SP), in the lumbar 4 and 5 dorsal root ganglion (DRG) and spinal cord of spontaneously diabetic BB rats and non-diabetic controls using quantitative immunohistochemical analysis.

|
In our study we have used morphological and radio-immunological methods for the investigation of calcitonin gene-related peptide (CGRP) and substance P in cervical dorsal root ganglia (DRGs) in mice after administration of taxol or cisplatin and in spontaneously diabetic animals (db/db mice).
|
211 |

|
Application of 10 mg/kg NGF caused a significant elevation in peptide-immunoreactivity in control animals and in taxol-treated mice, i.e., statistically significant increase in peptide concentrations and in the number of substance P- and CGRP-immunoreactive DRG-neurons, suggesting a recruitment of additional peptide cells.
|
212 |
7536686
|
In diabetic animals a restoration in CGRP-content was observed under NGF-treatment; however, in this model the quantitative parameters did not demonstrate further elevation above control levels.

Tiapride dose-dependently attenuated the biphasic nociceptive responses induced by s.c. injection of formalin to the hindpaw of mice, and its activity on the first (ED50 = 110 mg/kg p.o.) and the second (ED50 = 32.0 mg/kg p.o.) phases paralleled that on the nociceptive response to intrathecal injection of substance P (ED50 = 190 mg/kg p.o.) and somatostatin (ED50 = 56.0 mg/kg p.o.), respectively.
|
218 |
7562555
|
The effects of tiapride (100 mg/kg p.o.) on both phases of the formalin test in normal mice were abolished by pretreatment with p-chlorophenylalanine (800 x 2 mg/kg p.o.), a 5-hydroxytryptamine (5-HT) depletor, or pindolol (1 mg/kg i.p.), a 5-HT1 antagonist, but were scarcely affected by 3-tropanyl-indole-3-carboxylate, a 5-HT3 antagonist.

Recently it has been established that both a gastrin-releasing peptide (GRP) receptor and a neuromedin B (NMB) receptor mediate the actions of bombesin-related peptides in mammals.
|
220 |
7562561
|
Five different classes of peptides that function as GRP receptor antagonists have been identified; however, it is unknown whether similar strategies will yield antagonists for the closely related NMB receptor.
|
221 |
7562561
|
In the present study we have used either native cells possessing only one bombesin (Bn) receptor subtype or cells stably transfected with one subtype to determine whether using the strategies that were used successfully for GRP receptors would allow NMB receptor antagonists to be identified.
|
222 |
7562561
|
[DPhe12]Bn analogs; des Met14 amides, esters and alkylamides; psi 13-14 Bn pseudopeptides; and D-amino acid-substituted analogs of substance P (SP) or SP(4-11) were all synthesized and each functioned as a GRP receptor antagonist.
|
223 |
7562561
|
All of these antagonists had low affinity for the NMB receptor.
|
224 |
7562561
|
Application of similar strategies to NMB by formation of [DPhe8]NMB, [psi 9-10]NMB pseudopeptides, des-Met10 NMB amides, alkylamide or esters did not result in any potent NMB receptor antagonists.
|
225 |
7562561
|
D-Amino acid SP and SP(4-11) analogs were weakly selective NMB receptor antagonists.
|
226 |
7562561
|
No COOH-terminal fragments of NMB or GRP functioned as a GRP or NMB receptor antagonist.
|
227 |
7562561
|
These results demonstrate that none of the known strategies used to prepare peptide GRP receptor antagonists are successful at the NMB receptor, suggesting that a different strategy will be needed for this peptide, such as the formation of somatostatin octapeptide or D-amino acid-substituted substance P analogs.
|
228 |
7562561
|
These results suggest that even though there is a close homology between GRP and NMB and their receptors, their structure-function relations are markedly different.

These results suggest that a negative control system, which is mediated by delta-opioid receptors and links substance P with somatostatin-mediated nociceptive transmission, may inhibit the formalin-induced second-phase of the nociceptive response in diabetic mice.

This study investigates the ability of two chimeric galanin analogs, [# 1-galantide = (M-15) = [galanin (1-13)-substance P(5-11)] and #2-M-35[galanin(1-13)bradykinin (2-9)], which were recently reported to function as galanin-receptor antagonists in the CNS, to interact with galanin receptors on rat jejunal muscle strips or dispersed smooth muscle cells from guinea pig stomach.
|
250 |
7689105

The effect of inhibiting nitric oxide synthase (N omega-nitro-L-arginine) on plasma extravasation induced by intravenously administered substance P, [pGlu5,Me-Phe8,Sar9]substance P-(5-11) or prostaglandin E2 was examined.
|
255 |
7694865
|
These results suggest that (i) substance P is involved in the diabetes-induced chronic hyperalgesia, and (ii) NK1 receptor antagonists merit to be studied more extensively in relation with this pathological condition.

258 |
7769988
|
Rats with streptozotocin-diabetes showed an increase in NGF mRNA in the iris (P < 0.01) which was corrected by insulin treatment.
|
259 |
7769988
|
There was also an increase in the levels of mRNA for the substance P precursor, preprotachykinin (PPT), in the trigeminal ganglion of these animals, despite there being no change in GAP-43 mRNA.
|
260 |
7769988
|
There was a dose-dependent increase in both gamma-PPT and GAP-43 mRNA in the trigeminal ganglia of NGF-treated diabetic rats.

Binding of 125I-BH-SP was saturable, reversible, time- and temperature-dependent and was inhibited by several SP-related peptides with relative potencies of SP = physalaemin (IC50:0.19 nM) > SP methyl ester (SP-ME) (IC50:3.3 nM) > eledoisin (IC50:6.1 nM) > neurokinin A (NKA) (IC50: 65 nM) > neurokinin B (NKB) (IC50:80 nM).

|
Phospholipase C activating agents (carbachol, CCK-8), adenylate cyclase activating agents (secretin, VIP), TPA and the calcium ionophore, A23187, all inhibited the binding of 125I-BH-SP and it was due to inhibition of ligand internalization with no change in surface bound parameters.

|
In conclusion, the present study demonstrates that chief cells possess a NK1 subtype of tachykinin receptor, occupation of the low affinity sites of this receptor cause calcium mobilization and pepsinogen secretion, and that binding to this receptor is regulated by agents that activate phospholipase C, adenylate cyclase, protein kinase C and calcium mobilization.

In diabetics, there was an early length-dependent dysfunction of small-diameter sensory fibres, with depletion of skin NGF and the sensory neuropeptide substance P.
|
289 |

In rodent models of diabetes there are expression deficits in nerve growth factor (NGF) and in its high-affinity receptor, trkA, leading to decreased retrograde axonal transport of NGF and decreased support of NGF-dependent sensory neurons, with reduced expression of their neuropeptides, substance P and calcitonin gene-related peptide (CGRP).
|
293 |
8730785
|
Treatment of diabetic rats with intensive insulin normalized these deficits and treatment with exogenous NGF caused dose-related increases, giving levels of NGF and neuropeptides which were greater than those of controls.

8738148
|
This study was designed to measure expression of messenger RNA (mRNA) coding for NGF and its receptors, trkA and p75NGFR, during nerve regeneration and degeneration in rats with streptozotocin-induced diabetes; mRNA coding for preprotachykinin A (the substance P precursor), whose expression is stimulated by NGF, and mRNA for growth-associated protein-43 (GAP-43) were also measured in blots from L4 + L5 (pooled unilaterally) dorsal root ganglia.

Enteric neuropeptides in streptozotocin-diabetic rats; effects of insulin and aldose reductase inhibition.
|
297 |
8738309
|
The aim of the present study was to determine whether diabetes-induced changes in the distribution of enteric neuropeptides, could be prevented in 12-week streptozotocin-diabetic rats, by rigorous control of glycaemia, using daily adminstration of insulin, or an aldose reductase inhibitor (ponalrestat).
|
298 |
8738309
|
The pattern of distribution of nerve fibres and cell bodies, containing immunoreactive vasoactive intestinal polypeptide (VIP), galanin (GAL), calcitonin gene-related peptide (CGRP) and substance P was examined in the myenteric plexus of ileum from control, untreated diabetic, insulin-treated diabetic and aldose reductase inhibitor-treated diabetic rats.
|
299 |
8738309
|
The increase in VIP- and GAL-like immunoreactivity, seen in the myenteric plexus of untreated diabetic rat ileum, was not present in the myenteric plexus of ileum from insulin- and aldose reductase inhibitor-treated diabetic rats.
|
300 |
8738309
|
This was prevented by insulin treatment, but aldose reductase inhibitor treatment had no effect.
|
301 |
8738309
|
Generally, the similarity of effect of ponalrestat and insulin on VIP and galanin expression in this study supports a primary effect of insulin via glycaemic control.
|
302 |
8738309
|
The dissimilarity of the effect of the two treatments on CGRP expression may imply a neurotrophic effect of insulin, although there are certainly consequences of hyperglycaemia other than exaggerated flux through the polyol pathway.

Somatostatin (SOM), calcitenin gene-related peptide (CGRP), and substance P (SP) are neuropeptides that modulate pain responses transmitted by primary sensory afferents, the cell bodies of which are located in the dorsal root ganglion (DRG).

Effect of streptozotocin-diabetes on knee joint inflammation-induced changes in substance P and nerve growth factor in the rat.
|
318 |
9013783
|
After 24 weeks of streptozotocin-diabetes, there was a non-significant reduction in gamma-preprotachykinin mRNA expression whilst substance P levels in dorsal root ganglia, sciatic nerve and synovium and nerve growth factor levels in the sciatic nerve were significantly decreased.
|
319 |
9013783
|
Substance P levels were unaltered compared to non-arthritic diabetic rats whilst nerve growth factor levels were significantly increased in synovium and sciatic nerve suggesting an uncoupling of substance P from nerve growth factor control in the inflammatory response in diabetic rats.
|
320 |
9013783

Deficits in gamma-preprotachykinin mRNA expression and substance P and the altered levels of nerve growth factor indicate sensory neuronal dysfunction may play a major role in this abnormal response.

In rodent models of diabetes, there are expression deficits in nerve growth factor (NGF) and in mRNA for its high-affinity receptor, trkA, leading to decreased retrograde axonal transport of NGF and decreased support of NGF-dependent sensory neurons, with reduced expression of their neuropeptides, substance P and calcitonin gene-related peptide (CGRP).
|
338 |
9285498
|
Treatment of diabetic rats with intensive insulin normalized these deficits, and treatment with exogenous NGF caused dose-related increases, giving levels of NGF and neuropeptides that were greater than those of controls.
|
339 |
9285498
|
In regenerating nerves after experimental crush injury, expression of NGF in the nerve trunk is increased in diabetes to a greater extent than in controls, but this is offset by a greater reduction in the neuronal expression of trkA in dorsal root ganglia of diabetic rats.

Ability of various bombesin receptor agonists and antagonists to alter intracellular signaling of the human orphan receptor BRS-3.
|
342 |
9593699
|
Bombesin (Bn) receptor subtype 3 (BRS-3) is an orphan receptor that is a predicted member of the heptahelical G-protein receptor family and so named because it shares a 50% amino acid homology with receptors for the mammalian bombesin-like peptides neuromedin B (NMB) and gastrin-releasing peptide.

[D-Phe6,beta-Ala11,Phe13,Nle14]Bn-(6-14) stimulated a 2-3-fold increase in [Ca2+]i, a 3-fold increase in tyrosine phosphorylation of p125(FAK) with an EC50 of 0.2-0.7 nM, but failed to either stimulate increases in cyclic AMP or inhibit forskolin-stimulated increases.
|
344 |
9593699
|
No high affinity Bn receptor antagonists had high affinity for the hBRS-3 receptor, although two low affinity antagonists for gastrin-releasing peptide and NMB receptors, [D-Arg1,D-Trp7,9, Leu11]substance P and [D-Pro4,D-Trp7,9,10]substance P-(4-11), inhibited hBRS-3 receptor activation.
|
345 |
9593699
|
The NMB receptor-specific antagonist D-Nal,Cys,Tyr,D-Trp,Lys,Val, Cys,Nal-NH2 inhibited hBRS-3 receptor activation in a competitive fashion (Ki = 0.5 microM).
|
346 |
9593699
|
Stimulation of p125(FAK) tyrosine phosphorylation by hBRS-3 activation was not inhibited by the protein kinase C inhibitor, GF109203X, or thapsigargin, alone or in combination.
|
347 |
9593699
|
These results show that hBRS-3 receptor activation increases phospholipase C activity, which causes generation of inositol phosphates and changes in [Ca2+]i and is also coupled to tyrosine kinase activation, but is not coupled to adenylate cyclase activation or inhibition. hBRS-3 receptor activation results in tyrosine phosphorylation of p125(FAK), and it is not dependent on activation of either limb of the phospholipase C cascade.

Untreated streptozotocin-diabetic (7 weeks duration) rats showed reductions (all p < 0.01; percentages in brackets) in motor and sensory nerve conduction velocity (MNCV; 14%, SNCV; 17%) and in sciatic nerve contents of nerve growth factor (NGF; 57%), substance P (SP; 53%) and neuropeptide Y (NPY; 39%).
|
350 |
9686927

These changes occurred in the entire myelinated population of sensory nerves and were not restricted to nociceptive nerve fibers. (2) The NGF effect on neurotransmitters of the sensory, nociceptive system was reflected by increased CGRP and substance P content in the DRG and in the dorsal horn of the spinal cord.
|
353 |

|
No change of trkA receptor immunostaining was seen in DRGs of diabetic rats; however, a reduction of trkA immunoreactivity of DRG neurons was noted after long-term NGF treatment of healthy controls.

|
383 |
10368989
|
In conclusion, the pattern of distribution and density of NPY, SP and VIP in the pancreas of STZ-induced diabetic rats with SPTG is similar to that observed in normal pancreas, but the expression of CGRP and CCK-8 seemed to have increased as a result of transplantation and or diabetes.

The dose-dependent prevention of nerve conduction slowing by TX 14(A) was accompanied by preservation of axonal caliber and sodium-potassium ATPase activity, while prevention of thermal hypoalgesia was associated with attenuation of the decline in nerve substance P levels.
|
386 |
10395015
|
Furthermore, this thermal allodynia and hyperalgesia in diabetic mice may be due to the enhanced release of substance P followed by activation of protein kinase C in the spinal cord.

Angiotensin-converting enzyme (ACE) inhibitors, widely and successfully used in the treatment of hypertension, may also provide renal protection independent of blood pressure reduction; however, their relatively nonspecific mode of action in blocking an early metabolic step entails major clinical disadvantages, such as accumulation of bradykinin and substance P, that may cause the characteristic ACE-inhibitor side effects of persistent dry cough and, more rarely, angioneurotic edema.
|
425 |

|
Angiotensin II antagonists or receptor blockers, a new class of antihypertensive agent, selectively antagonize the AT1 receptor subtype and, because of greater specificity, do not give rise to the side effects associated with ACE inhibitors.

|
Both angiotensin-converting enzyme (ACE) inhibitors and AT-1 receptor antagonists reduce the effects of angiotensin II, however they may have different clinical effects.
|
440 |
12437489
|
This is because the ACE inhibitors, but not the AT-1 receptor antagonists, increase the levels of substance P, bradykinin and tissue plasminogen activator.
|
441 |
12437489
|
The AT-1 receptor antagonists, but not the ACE inhibitors, are capable of inhibiting the effects of angiotensin II produced by enzymes other than ACE.

The neuroendocrine peptides known to regulate gastrointestinal motility, namely secretin, gastric inhibitory peptide (GIP), motilin, somatostatin, peptide YY (PYY), substance P, vasoactive intestinal polypeptide (VIP) and galanin, were measured in tissue extracts of different segments of the gut by radioimmunoassay.
|
469 |
12602781

|
Duodenal GIP and VIP, and colonic somatostatin and VIP levels were lower in obese diabetic mice than controls.
|
472 |
12602781
|
Whereas the high concentrations of antral VIP and galanin and the low level of colonic PYY in diabetic NOD mice may contribute to the development of diarrhea in NOD mice, the decreased levels of duodenal and colonic VIP and colonic somatostatin in obese diabetic mice may account for the constipation encountered in these animals.
|
473 |
12602782
|
Whereas the contents of peptide YY (PYY) and somatostatin were higher in obese diabetic mice, the contents of substance P and VIP were lower.
|
474 |

15093698
|
In the present study on 18 GK rats and 21 control Wistar rats, the occurrence of the sensory neuropeptides substance P (SP) and calcitonin gene-related peptide (CGRP), and the autonomic neuropeptide Y (NPY) was analysed in bone and joints, dorsal root ganglia and lumbar spinal cord by immunohistochemistry and radioimmunoassay (RIA).

|
While SP, CGRP and NPY in periosteum, cortical bone and synovium was confined to neuronal tissue, the bone marrow in addition exhibited an abundance of NPY-positive megakaryocytes.
|
481 |

|
Given the suggested anabolic role of NPY and CGRP on bone, neuropeptidergic deficit in diabetes may prove to be an important factor underlying the development of regional osteopenia.
