Isamoltane hemifumarate 

Isamoltane hemifumarate is a selective antagonist of 5-HT_1B receptor, with an IC₅₀ of 39 nM for inhibits the binding of [¹²⁵I]ICYP to 5-HT_1B 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].

Isamoltane exhibits 27-fold selectivity for the 5-HT_1B receptor over 5-HT_1A (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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

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].
