Nantenine and papaverine differentially modify synaptosomal membrane enzymes
(Urban & Fischer Verlag, 2000-07-01)
Papaverine (1-[(3,4-Dimethoxyphenyl) methyl]-6,7-dimethoxyisoquinoline) and nantenine (O-methyldomesticine) are chemically related isoquinoline alkaloids displaying similar dose-dependent sedative or convulsant effects, ...
Differential modulation of phospholipase D and phosphatidate phosphohydrolase during aging in rat cerebral cortex synaptosomes
(Pergamon-Elsevier Science Ltd, 2002-04-01)
Phosphatidylcholine (PC) hydrolysis generates two important second messengers: phosphatidic acid (PA) and diacylglycerol (DAG). Phospholipase D (PLD) and phosphatidate phosphohydrolase (PAPase) are involved in their ...
Kinetics of Na+, K+-ATPase inhibition by an endogenous modulator (II- A)
(Springer/Plenum Publishers, 2000-02)
We have previously reported the isolation by gel filtration and anionic exchange HPLC of two brain Na+, K+-ATPase inhibitors, II-A and II-E, and kinetics of enzyme interaction with the latter. In the present study we ...
Neurotensin inhibits neuronal Na+, K+-ATPase activity through high affinity peptide receptor
(Elsevier Science Inc, 2000)
Aging Modifies the Enzymatic Activities Involved in 2-Arachidonoylglycerol Metabolism
(Wiley, 2013-03)
One of the principal monoacylglycerol (MAG) species in animal tissues is 2-arachidonoylglycerol (2-AG), and the diacylglycerol lipase (DAGL) pathway is the most important 2-AG biosynthetic pathway proposed to date. ...
The administration of levocabastine, a NTS2 receptor antagonist, modifies Na+, K+-ATPase properties
(Springer, 2016-06)
Neurotensin behaves as a neuromodulator or as a neurotransmitter interacting with NTS1 and NTS2 receptors. Neurotensin in vitro inhibits synaptosomal membrane Na+, K+-ATPase activity. This effect is prevented by administration ...
High affinity receptors but not low affinity receptors for neurotensin are involved in neuronal Na/K-ATPase inhibition by the peptide
(Research Trends, 2013-07)
Neurotensin acts as a neuromodulator or as a neurotransmitter that binds to a group of receptors. Two of the receptors, namely NTS1 and NTS2, bind to neurotensin with high affinity and low affinity, respectively. Neurotensin ...
Na+, K+-ATPase response to neurotensin is altered by streptozotocin administration
(Research Trends, 2013-09)
Neurotensin is a basic tridecapeptide which can act as a neuromodulator or a neurotransmitter and binds to a group of receptors. Neurotensin is able to inhibit Na+, K+-ATPase activity, an effect blocked by the presence of ...
Kinectics of Na+, K+-ATPase inhibition by calcitonin and neurotensin
(Research Trends, 2014-01)
The kinetics of interactions between the peptides calcitonin or neurotensin, and synaptosomal membrane Na+, K+-ATPase activity was characterized in this study. Calcitonin is a 32-amino acid peptide produced by the thyroid ...
