Ciproxifan, a histamine H3 receptor antagonist, reversibly inhibits monoamine oxidase A and B

Abstract: 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 screening for potential monoamine oxidase A and B inhibition ciproxifan showed efficacy on both enzyme isoforms. Further cha… Show more

“…Inhibition of H3R with inverse agonists/ antagonists elevates the levels of neurotransmitters,s uch as acetylcholine (ACh), 5-HT,d opamine,o rn orepinephrine,i n the central nervous system. [11] Although compounds with multipotent profiles,c ombining H3R affinity with cholinesterase (ChE) inhibition, [12,13] antioxidant capacity, [14] or most recently with MAOinhibition, [15] have been reported, [16] MDLs that are able to simultaneously modulate H3R, MAO, and ChE have not been described to date.S uch am ultipotent profile might constitute an innovative therapeutic approach for new molecules targeting neurodegenerative diseases with multiple causes. [10] Thus the procognitive use of H3R antagonists/inverse agonists for the treatment of neurodegenerative diseases is being investigated.…”

“…Die Inhibierung von H3R durch inverse Agonisten/Antagonisten führt zum Anstieg verschiedener Neurotransmitter wie Acetylcholin (ACh), 5-HT,D opamin oder Norepinephrin im zentralen Nervensystem. [11] Obwohl Substanzen mit multipotenten Wirkprofilen wie H3R-Affinitätk ombiniert mit Cholinesterase(ChE)-Inhibition [12,13] und antioxidativer Kapazität [14] oder, erst kürzlich, MAO-Inhibition [15] bereits beschrieben wurden (siehe die Übersicht in Lit. [10] Folglich wird das prokognitive Potenzial von verschiedenen inversen H3R-Agonisten/Antagonisten fürn eurodegenerative Erkrankungen breit untersucht.…”

“…Im Vergleich zum dualpotenten H3R/MAO-Liganden Ciproxifan [15] ist Contilisant ein verbesserter MAO-Inhibitor mit irreversiblen Bindungsmodus.Z usätzlich zeigt Contilisant (1 mg kg À1 )e ine Verbesserung der kognitiven Eigenschaften in LPS-geschädigten Mäusen. Vond ieser kleinen Substanzserie zeigte Contilisant insgesamt die besten Multitarget-Eigenschaften in nanomolaren Konzentrationsbereichen mit zu-sätzlichen und ausgeglichenen Eigenschaften bezüglich Permeation, antioxidativer und neuroprotektiver Kapazität.…”
