Biological Activity
[Description]:
Isamoltane hemifumarate is a selective antagonist of 5-HT1B receptor, with an IC50 of 39 nM for inhibits the binding of [125I]ICYP to 5-HT1B recognition sites in rat brain membranes. Isamoltane hemifumarate is also a β-adrenoceptor ligand, with an IC50 of 8.4 nM. Isamoltane hemifumarate shows anxiolytic activity[1].

[Target]
β-adrenoceptor:8.4 nM (IC50)
5-HT1B Receptor:39 nM (IC50)
[In Vitro]
Isamoltane exhibits 27-fold selectivity for the 5-HT1B receptor over 5-HT1A (IC50=1070 nM) in rat brain membranes[1]. Isamoltane (0.01-10 µM) increases the [3H]-overflow elicited by electrical stimulation in a concentration-dependent manner in rat cortical slices[1].
[In Vivo]
Isamoltane (0.3-30 mg/kg; i.p) does not alter the accumulation of 5-HTP in the rat hippocampus, and increases 5-HT synthesis in cortical tissue. Isamoltane reduces 5-HTP accumulation in the striatum[1]. Animal Model: Male Sprague-Dawley rats (200-300 g)[1] Dosage: 0.3, 1, 3, 10, 30 mg/kg Administration: I.p. Result: 38% reduction of 5-HTP accumulation was found with 30 mg/ kg in the striatum. Did not alter the accumulation of 5-HTP in the hippocampus. Increased 5-HT synthesis at 0.3, 1 and 3 mg/kg in cortical tissue.
