Ciproxifan, a histamine H3 receptor antagonist, reversibly inhibits monoamine oxidase A and B
Ciproxifan is a well-investigated histamine H3 receptor (H3R) inverse agonist/antagonist, showing an exclusively high species-specific affinity at rodent compared to human H3R. It is well studied as reference compound for H3R in rodent models for neurological diseases connected with neurotransmitter dysregulation, e.g. attention deficit hyperactivity disorder or Alzheimer's disease. In a screen...
متن کاملEffect of cadmium and zinc ethanolamine complexes on rat brain monoamine oxidase-B activity in vitro.
Monoamine oxidase-B (MAO-B) from rat brain was inhibited strongly by the prepared cadmium and zinc ethanolamine complexes obtained from their sulphate and chloride salts. The inhibition of MAO-B by these complexes was time-dependent and fully reversible after dilution and sedimentation. In vitro, the cadmium ethanolamine complexes were more potent at inhibiting MAO-B than the zinc complexes. Th...
متن کاملStudies on monoamine oxidase. (Report XXV). Effects of alcohols on beef liver mitochondrial monoamine oxidase.
The effects of alcohols on MAO activity in beef and rat liver mitochondria were studied. MAO activity was determined manometrically using tyramine (1× 10-2 M) as substrate and expressed as O2 uptake in 60 min. At concentrations of 0.1 to 10%, methanol and ethanol increased MAO activity in both beef and rat liver mitochondria. Activation of MAO by ethanol was reversib...
متن کاملThioperamide, antagonist of histamine H3 receptors, increases brain production of kynurenic acid
Brain histamine plays the role of neuromodulator and neurotransmitter in a variety of physiological and pathological processes. Kynurenic acid (KYNA) is an antagonist of the glycine site within the N-methyl-D-aspartate (NMDA) receptor complex, and of nicotinic α7 receptors in the brain of mammals. Here, we report that thioperamide, H3 receptor antagonist/inverse agonist is capable of increasing...
متن کاملInhibition of monoamine oxidase by stilbenes from Rheum palmatum
Seven stilbenes and one catechin were bioactivity-guidedly isolated from the rhizomes of Rheum palmatem. Their structures were identified as piceatannol(1), resveratrol(2), piceid(3), rhapontigenin(4), piceatannol-3'-O-β-D-glucopyranoside(5), rhaponticin(6), catechin(7) and desoxyrhapontigenin(8). Anti-monoamine oxidase (MAO) activities of compounds 1–8 were tested. Compounds 1 and 8 showed sig...
